Accounting Policies [Abstract]

Basis Of Presentation And Use Of Estimates [Policy Text Block]

Basis of Presentation and Use of Estimates

The 

accompanying 

consolidated 

financial 

statements 

include 

our 

accounts 

and 

those 

of 

our 

wholly 

owned 

subsidiaries. 

All 

significant 

intercompany 

accounts 

and 

transactions 

have 

been 

eliminated 

upon 

consolidation. 

The 

preparation 

of 

financial 

statements 

in 

conformity 

with 

accounting 

principles 

generally 

accepted 

in 

the 

United 

States 

of 

America 

(“U.S. 

GAAP”) 

requires 

us 

to 

make 

estimates 

and 

assumptions 

that 

affect 

the 

reported 

amounts 

of 

assets 

and 

liabilities 

and 

disclosure 

of 

contingent 

assets 

and 

liabilities 

at 

the 

date 

of 

the 

financial 

statements 

and 

the 

reported 

amounts 

of 

revenues 

and 

expenses 

during 

the 

reporting 

period. 

Actual 

results 

could 

differ 

from 

those 

estimates. 

Certain 

of 

our 

accounts, 

including 

inventories, 

long 

lived 

assets, 

goodwill, 

identifiable 

intangibles 

and 

deferred 

tax 

assets 

and 

liabilities 

including 

related 

valuation 

allowances, 

are 

particularly 

impacted 

by 

estimates. 

In 

the 

opinion 

of 

management, 

the 

accompanying 

unaudited 

consolidated 

financial 

statements 

include 

all 

adjustments 

(consisting 

only 

of 

normal 

recurring 

adjustments) 

necessary 

to 

present 

fairly 

the 

financial 

position, 

results 

of 

operations, 

and 

changes 

in 

cash 

flows 

for 

the 

interim 

periods 

presented. 

Certain 

footnote 

information 

has 

been 

condensed 

or 

omitted 

from 

these 

consolidated 

financial 

statements. 

Therefore, 

these 

consolidated 

financial 

statements 

should 

be 

read 

in 

conjunction 

with 

the 

consolidated 

financial 

statements 

and 

accompanying 

footnotes 

included 

in 

our 

Annual 

Report 

on 

Form 

10 

K 

for 

the 

year 

ended 

December 

31, 

2015 

filed 

with 

the 

Securities 

and 

Exchange 

Commission 

on 

March 

29, 

2016 

(the 

"2015 

Form 

10 

K").

Reclassification, Policy [Policy Text Block]

Reclassification

Certain 

prior 

period 

amounts 

have 

been 

reclassified 

to 

be 

comparable 

with 

the 

current 

period's 

presentation.

Inventory, Policy [Policy Text Block]

Inventories

Inventories 

are 

valued 

at 

cost 

on 

a 

first 

in, 

first 

out 

basis, 

not 

in 

excess 

of 

market 

value. 

Cash 

flows 

from 

the 

sale 

of 

inventories 

are 

recorded 

in 

operating 

cash 

flows. 

On 

a 

quarterly 

basis, 

we 

review 

our 

inventories 

and 

record 

excess 

and 

obsolete 

inventory 

charges 

based 

upon 

our 

established 

objective 

excess 

and 

obsolete 

inventory 

criteria. 

These 

criteria 

identify 

material 

that 

has 

not 

been 

used 

in 

a 

work 

order 

during 

the 

prior 

twelve 

months 

and 

the 

quantity 

of 

material 

on 

hand 

that 

is 

greater 

than 

the 

average 

annual 

usage 

of 

that 

material 

over 

the 

prior 

three 

years. 

In 

certain 

cases, 

additional 

excess 

and 

obsolete 

inventory 

charges 

are 

recorded 

based 

upon 

current 

market 

conditions, 

anticipated 

product 

life 

cycles, 

new 

product 

introductions 

and 

expected 

future 

use 

of 

the 

inventory. 

The 

excess 

and 

obsolete 

inventory 

charges 

we 

record 

establish 

a 

new 

cost 

basis 

for 

the 

related 

inventories. 

We 

incurred 

excess 

and 

obsolete 

inventory 

charges 

of 

$69 

and 

$51 

for 

the 

three 

months 

ended 

March 

31, 

2016 

and 

2015, 

respectively.

Goodwill Intangible And Long Lived Assets [Policy Text Block]

Goodwill, Intangible and Long-Lived Assets

We 

account 

for 

goodwill 

and 

intangible 

assets 

in 

accordance 

with 

Accounting 

Standards 

Codification 

("ASC") 

350 

(Intangibles 

Goodwill 

and 

Other). 

Finite 

lived 

intangible 

assets 

are 

amortized 

over 

their 

estimated 

useful 

economic 

life 

and 

are 

carried 

at 

cost 

less 

accumulated 

amortization. 

Goodwill 

is 

assessed 

for 

impairment 

at 

least 

annually 

in 

the 

fourth 

quarter, 

on 

a 

reporting 

unit 

basis, 

or 

more 

frequently 

when 

events 

and 

circumstances 

occur 

indicating 

that 

the 

recorded 

goodwill 

may 

be 

impaired. 

As 

a 

part 

of 

the 

goodwill 

impairment 

assessment, 

we 

have 

the 

option 

to 

perform 

a 

qualitative 

assessment 

to 

determine 

whether 

it 

is 

more 

likely 

than 

not 

that 

the 

fair 

value 

of 

a 

reporting 

unit 

is 

less 

than 

its 

carrying 

amount. 

If 

we 

determine 

this 

is 

the 

case, 

we 

are 

required 

to 

perform 

a 

two 

step 

goodwill 

impairment 

test 

to 

identify 

potential 

goodwill 

impairment 

and 

measure 

the 

amount 

of 

goodwill 

impairment 

loss 

to 

be 

recognized. 

The 

two 

step 

test 

is 

discussed 

below. 

If 

we 

determine 

that 

it 

is 

more 

likely 

than 

not 

that 

the 

fair 

value 

of 

the 

reporting 

unit 

is 

greater 

than 

its 

carrying 

amounts, 

the 

two 

step 

goodwill 

impairment 

test 

is 

not 

required. 

If 

we 

determine 

it 

is 

more 

likely 

than 

not 

that 

the 

fair 

value 

of 

a 

reporting 

unit 

is 

less 

than 

its 

carrying 

amount 

as 

a 

result 

of 

our 

qualitative 

assessment, 

we 

will 

perform 

a 

quantitative 

two 

step 

goodwill 

impairment 

test. 

In 

the 

Step 

I 

test, 

the 

fair 

value 

of 

a 

reporting 

unit 

is 

computed 

and 

compared 

with 

its 

book 

value. 

If 

the 

book 

value 

of 

a 

reporting 

unit 

exceeds 

its 

fair 

value, 

a 

Step 

II 

test 

is 

performed 

in 

which 

the 

implied 

fair 

value 

of 

goodwill 

is 

compared 

with 

the 

carrying 

amount 

of 

goodwill. 

If 

the 

carrying 

amount 

of 

goodwill 

exceeds 

the 

implied 

fair 

value, 

an 

impairment 

loss 

is 

recorded 

in 

an 

amount 

equal 

to 

that 

excess. 

The 

two 

step 

goodwill 

impairment 

assessment 

is 

based 

upon 

a 

combination 

of 

the 

income 

approach, 

which 

estimates 

the 

fair 

value 

of 

our 

reporting 

units 

based 

upon 

a 

discounted 

cash 

flow 

approach, 

and 

the 

market 

approach 

which 

estimates 

the 

fair 

value 

of 

our 

reporting 

units 

based 

upon 

comparable 

market 

multiples. 

This 

fair 

value 

is 

then 

reconciled 

to 

our 

market 

capitalization 

at 

year 

end 

with 

an 

appropriate 

control 

premium. 

The 

determination 

of 

the 

fair 

value 

of 

our 

reporting 

units 

requires 

management 

to 

make 

significant 

estimates 

and 

assumptions 

including 

the 

selection 

of 

appropriate 

peer 

group 

companies, 

control 

premiums, 

discount 

rate, 

terminal 

growth 

rates, 

forecasts 

of 

revenue 

and 

expense 

growth 

rates, 

changes 

in 

working 

capital, 

depreciation, 

amortization 

and 

capital 

expenditures. 

Changes 

in 

assumptions 

concerning 

future 

financial 

results 

or 

other 

underlying 

assumptions 

could 

have 

a 

significant 

impact 

on 

either 

the 

fair 

value 

of 

the 

reporting 

unit 

or 

the 

amount 

of 

the 

goodwill 

impairment 

charge. 

Indefinite 

lived 

intangible 

assets 

are 

assessed 

for 

impairment 

at 

least 

annually 

in 

the 

fourth 

quarter, 

or 

more 

frequently 

if 

events 

or 

changes 

in 

circumstances 

indicate 

that 

the 

asset 

might 

be 

impaired. 

As 

a 

part 

of 

the 

impairment 

assessment, 

we 

have 

the 

option 

to 

perform 

a 

qualitative 

assessment 

to 

determine 

whether 

it 

is 

more 

likely 

than 

not 

that 

an 

indefinite 

lived 

intangible 

asset 

is 

impaired. 

If, 

as 

a 

result 

of 

our 

qualitative 

assessment, 

we 

determine 

that 

it 

is 

more 

likely 

than 

not 

that 

the 

fair 

value 

of 

the 

indefinite 

lived 

intangible 

asset 

is 

less 

than 

its 

carrying 

amount, 

the 

quantitative 

impairment 

test 

is 

required. 

Otherwise, 

no 

further 

testing 

is 

required. 

The 

quantitative 

impairment 

test 

consists 

of 

a 

comparison 

of 

the 

fair 

value 

of 

the 

intangible 

asset 

with 

its 

carrying 

amount. 

If 

the 

carrying 

amount 

of 

the 

intangible 

asset 

exceeds 

its 

fair 

value, 

an 

impairment 

loss 

is 

recognized 

in 

an 

amount 

equal 

to 

that 

excess. 

Long 

lived 

assets, 

which 

consist 

of 

finite 

lived 

intangible 

assets 

and 

property 

and 

equipment, 

are 

assessed 

for 

impairment 

whenever 

events 

or 

changes 

in 

business 

circumstances 

indicate 

that 

the 

carrying 

amount 

of 

the 

assets 

may 

not 

be 

fully 

recoverable 

or 

that 

the 

useful 

lives 

of 

these 

assets 

are 

no 

longer 

appropriate. 

Each 

impairment 

test 

is 

based 

on 

a 

comparison 

of 

the 

estimated 

undiscounted 

cash 

flows 

to 

the 

recorded 

value 

of 

the 

asset. 

If 

impairment 

is 

indicated, 

the 

asset 

is 

written 

down 

to 

its 

estimated 

fair 

value. 

The 

cash 

flow 

estimates 

used 

to 

determine 

the 

impairment, 

if 

any, 

contain 

management's 

best 

estimates 

using 

appropriate 

assumptions 

and 

projections 

at 

that 

time.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Stock-Based Compensation

We 

account 

for 

stock 

based 

compensation 

in 

accordance 

with 

ASC 

Topic 

718 

(Compensation 

Stock 

Compensation) 

which 

requires 

that 

employee 

share 

based 

equity 

awards 

be 

accounted 

for 

under 

the 

fair 

value 

method 

and 

requires 

the 

use 

of 

an 

option 

pricing 

model 

for 

estimating 

fair 

value 

of 

stock 

options 

granted, 

which 

is 

then 

amortized 

to 

expense 

over 

the 

service 

periods.

to 

our 

stock

Subsequent Events, Policy [Policy Text Block]

Subsequent Events

We 

have 

made 

an 

assessment 

of 

our 

operations 

and 

determined 

that 

there 

were 

no 

material 

subsequent 

events 

requiring 

adjustment 

to, 

or 

disclosure 

in, 

our 

consolidated 

financial 

statements 

for 

the 

three 

months 

ended 

March 

31, 

2016.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition

We 

recognize 

revenue 

when 

persuasive 

evidence 

of 

an 

arrangement 

exists, 

delivery 

has 

occurred 

or 

services 

have 

been 

rendered, 

the 

price 

is 

fixed 

or 

determinable, 

and 

collection 

of 

the 

related 

receivable 

is 

reasonably 

assured. 

Sales 

of 

our 

products 

are 

made 

through 

our 

sales 

employees, 

third 

party 

sales 

representatives 

and 

distributors. 

There 

are 

no 

differences 

in 

revenue 

recognition 

policies 

based 

on 

the 

sales 

channel. 

We 

do 

not 

provide 

our 

customers 

with 

rights 

of 

return 

or 

exchanges. 

Revenue 

is 

generally 

recognized 

upon 

product 

shipment. 

Our 

customers' 

purchase 

orders 

do 

not 

typically 

contain 

any 

customer 

specific 

acceptance 

criteria, 

other 

than 

that 

the 

product 

performs 

within 

the 

agreed 

upon 

specifications. 

We 

test 

all 

products 

manufactured 

as 

part 

of 

our 

quality 

assurance 

process 

to 

determine 

that 

they 

comply 

with 

specifications 

prior 

to 

shipment 

to 

a 

customer. 

To 

the 

extent 

that 

any 

customer 

purchase 

order 

contains 

customer 

specific 

acceptance 

criteria, 

revenue 

recognition 

is 

deferred 

until 

customer 

acceptance. 

In 

addition, 

in 

our 

Thermal 

Products 

and 

Mechanical 

Products 

segments, 

we 

lease 

certain 

of 

our 

equipment 

to 

customers 

under 

non 

cancellable 

operating 

leases. 

These 

leases 

generally 

have 

an 

initial 

term 

of 

six 

months. 

We 

recognize 

revenue 

for 

these 

leases 

on 

a 

straight 

line 

basis 

over 

the 

term 

of 

the 

lease. 

With 

respect 

to 

sales 

tax 

collected 

from 

customers 

and 

remitted 

to 

governmental 

authorities, 

we 

use 

a 

net 

presentation 

in 

our 

consolidated 

statement 

of 

operations. 

As 

a 

result, 

there 

are 

no 

amounts 

included 

in 

either 

our 

net 

revenues 

or 

cost 

of 

revenues 

related 

to 

sales 

tax.

Standard Product Warranty, Policy [Policy Text Block]

Product Warranties

We 

generally 

provide 

product 

warranties 

and 

record 

estimated 

warranty 

expense 

at 

the 

time 

of 

sale 

based 

upon 

historical 

claims 

experience. 

Warranty 

expense 

is 

included 

in 

selling 

expense 

in 

the 

consolidated 

financial 

statements.

Income Tax, Policy [Policy Text Block]

Income Taxes

The 

asset 

and 

liability 

method 

is 

used 

in 

accounting 

for 

income 

taxes. 

Under 

this 

method, 

deferred 

tax 

assets 

and 

liabilities 

are 

recognized 

for 

operating 

loss 

and 

tax 

credit 

carryforwards 

and 

for 

the 

future 

tax 

consequences 

attributable 

to 

differences 

between 

the 

financial 

statement 

carrying 

amounts 

of 

existing 

assets 

and 

liabilities 

and 

their 

respective 

tax 

bases. 

Deferred 

tax 

assets 

and 

liabilities 

are 

measured 

using 

enacted 

tax 

rates 

expected 

to 

apply 

to 

taxable 

income 

in 

the 

years 

in 

which 

those 

temporary 

differences 

are 

expected 

to 

be 

recovered 

or 

settled. 

The 

effect 

on 

deferred 

tax 

assets 

and 

liabilities 

of 

a 

change 

in 

tax 

rates 

is 

recognized 

in 

the 

results 

of 

operations 

in 

the 

period 

that 

includes 

the 

enactment 

date. 

A 

valuation 

allowance 

is 

recorded 

to 

reduce 

the 

carrying 

amounts 

of 

deferred 

tax 

assets 

if 

it 

is 

more 

likely 

than 

not 

that 

such 

assets 

will 

not 

be 

realized.

Earnings Per Share, Policy [Policy Text Block]

Net Earnings Per Common Share

Net 

earnings 

per 

common 

share 

basic 

is 

computed 

by 

dividing 

net 

earnings 

by 

the 

weighted 

average 

number 

of 

common 

shares 

outstanding 

during 

each 

period. 

Net 

earnings 

per 

common 

share 

diluted 

is 

computed 

by 

dividing 

net 

earnings 

by 

the 

weighted 

average 

number 

of 

common 

shares 

and 

common 

share 

equivalents 

outstanding 

during 

each 

period. 

Common 

share 

equivalents 

represent 

unvested 

shares 

of 

restricted 

stock 

and 

stock 

options 

and 

are 

calculated 

using 

the 

treasury 

stock 

method. 

Common 

share 

equivalents 

are 

excluded 

from 

the 

calculation 

if 

their 

effect 

is 

anti 

dilutive. 

The 

table 

below 

sets 

forth, 

for 

the 

periods 

indicated, 

a 

reconciliation 

of 

weighted 

average 

common 

shares 

outstanding 

basic 

to 

weighted 

average 

common 

shares 

and 

common 

share 

equivalents 

outstanding 

diluted 

and 

the 

average 

number 

of 

potentially 

dilutive 

securities 

that 

were 

excluded 

from 

the 

calculation 

of 

diluted 

earnings 

per 

share 

because 

their 

effect 

was 

anti 

dilutive:

New Accounting Pronouncements, Policy [Policy Text Block]

Effect of Recently Adopted Amendments to Authoritative Accounting Guidance

In November 2015, the Financial Accounting Standards Board (“FASB”) issued amendments to update the current guidance on the balance sheet classification of deferred taxes which is presented in ASC Topic 740 (Income Taxes). The purpose of the amendments is to simplify the presentation of deferred tax assets. This guidance requires deferred tax assets and liabilities, along with related valuation allowances, to be classified as noncurrent on the balance sheet. As a result, each tax jurisdiction will now only have one net noncurrent deferred tax asset or liability. The new guidance does not change the existing requirement that prohibits offsetting deferred tax liabilities from one jurisdiction against deferred tax assets of another jurisdiction. The amendments are effective for us as of January 1, 2017. Early application is permitted. We elected early application of this guidance effective January 1, 2016. The implementation of these amendments did not have a material impact on our consolidated financial statements. Prior period amounts have been reclassified to be consistent with the current period presentation.

In September 2015, the FASB issued amendments to update the current guidance on accounting for measurement period adjustments in a business combination which is presented in ASC Topic 805 (Business Combinations). This guidance requires an entity to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined; record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date; and present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The amendments were effective for us as of January 1, 2016. The implementation of these amendments did not have any impact on our consolidated financial statements.

Effect of Recently Issued Amendments to Authoritative Accounting Guidance

In March 2016, the FASB issued amendments to the current guidance on accounting for stock-based compensation issued to employees which is contained in ASC Topic 718 (Compensation-Stock Compensation). The new guidance simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendments are effective for us as of January 1, 2017. Early adoption is permitted. We do not expect the implementation of these amendments to have a material impact on our consolidated financial statements.

In February 2016, the FASB issued amendments to the current guidance on accounting for lease transactions which is presented in ASC Topic 842 (Leases). The intent of the updated guidance is to increase transparency and comparability among organizations by requiring lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by leases and to disclose key information about leasing arrangements. Under the new guidance, a lessee will be required to record a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The amendments are effective for us as of January 1, 2019. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. We are currently evaluating the impact of the implementation of these amendments on our consolidated financial statements.

In January 2016, the FASB issued amendments to the current guidance on the recognition and measurement of financial assets and financial liabilities which is presented in ASC Topic 825 (Financial Instruments). The intent of the updated guidance is to enhance the reporting model for financial instruments to provide users of financial statements with improved decision-making information. The updated guidance includes amendments to address aspects of recognition, measurement, presentation and disclosure. Changes included in the amendments are the requirement to measure equity investments at fair value, except those accounted for under the equity method of accounting or those that result in the consolidation of an investee, with changes in fair value recognized in net income; the requirement for a qualitative assessment to identify impairment of equity investments without readily determinable fair values; and the requirement for separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or in the accompanying notes to the financial statements. The amendments are effective for us as of January 1, 2018. Early application is permitted. We do not expect the implementation of these amendments to have a material impact on our consolidated financial statements.

In July 2015, the FASB issued amendments to update the current guidance on the subsequent measurement of inventory, which is presented in ASC Topic 330 (Inventory). The purpose of the amendments is to simplify the subsequent measurement of inventory and reduce the number of potential outcomes. It applies to all inventory other than inventory measured using last-in, first-out or the retail inventory method. Current guidance requires an entity to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less a normal profit margin. The updated guidance amends this to require that an entity measure inventory within the scope of the updated guidance at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amendments are effective for us as of January 1, 2017. We do not expect the implementation of these amendments to have a material impact on our consolidated financial statements.

In May 2014, the FASB issued new guidance on the recognition of revenue from contracts with customers. Subsequent to May, 2014, the FASB has issued additional clarifying guidance on certain aspects of this new guidance. This guidance is presented in ASC Topic 606 (Revenue from Contracts with Customers). This new guidance will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. Companies can use either the retrospective or cumulative effect transition method. In August 2015, the FASB deferred the effective date of this new guidance for one additional year. As a result, this new guidance is effective for us on January 1, 2018. Early application is only permitted as of the prior effective date, which in our case would be as of January 1, 2017. We have not yet selected a transition method and we are still evaluating the effect that this guidance will have on our consolidated financial statements and related disclosures.
