This Amendment No. 4 to Schedule 13D (this “Amendment”) amends the joint Schedule 13D filed on June 6, 2008 and amended by Amendment No. 1 to Schedule 13D filed on December 23, 2008 and Amendment No. 2 to Schedule 13D filed on May 1, 2009 and Amendment No. 3 to Schedule 13D filed on November 25, 2009 by Benchmark Performance Group, Inc. (“Benchmark”) and E. Wayne Kinsey III (the “Original Schedule 13D”).

Except as provided herein, this Amendment does not modify any of the information previously reported in the Original Schedule 13D. Capitalized terms used herein but not defined have the meanings ascribed to them in the Original Schedule 13D.

Item 1. Security and Issuer.

No modification is made to Item 1 of the Original Schedule 13D.

Item 2. Identity and Background.

No modification is made to Item 2 of the Original Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration.

No modification is made to Item 3 of the Original Schedule 13D.

Item 4. Purpose of Transaction.

The following is added to Item 4 of the Original Schedule 13D by adding the following at the end thereof:

In conjunction with a recapitalization of Benchmark effective on January 21, 2011, Benchmark distributed the 35,000,000 shares of common stock of IET that it owned to Mr. Kinsey. In connection with such recapitalization, Mr. Kinsey retains a significant equity interest in Benchmark and continues to serve as its President and Chief Executive Officer. Benchmark continues to be a party to the Exclusive License and Distributorship Agreement dated June 20, 2007 with IET. Mr. Kinsey has no definitive plans or proposals which relate to or would result in any transaction, event or action enumerated in paragraphs (a) through (j) of Item 4 of Schedule 13D promulgated under the Securities Exchange Act of 1934, as amended. However, Mr. Kinsey is evaluating on an ongoing basis IET’s financial condition, business, operations and prospects, the market price of its common stock, conditions of the securities markets generally, general economic and industry conditions and other factors. In particular, Mr. Kinsey may purchase additional common stock or other securities of IET or may sell or transfer common stock of IET beneficially owned by him from time to time in public or private transactions. Any such transactions may be effected at any time or from time to time subject to any applicable limitations imposed on the sale of IET’s securities by the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder or other applicable law.

Item 5. Interest in Securities of the Issuer:

The information in Item 5 of the Original Schedule 13D is hereby amended in its entirety to read as follows:

	(a)		As of the filing date of this Amendment, as a result of Benchmark’s recapitalization, Benchmark may be deemed to have (i) beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) and (ii) shared power to vote 0 shares of common stock, which represents 0% of the shares of common stock deemed to be outstanding pursuant to Rule 13d-1(j). This percentage of beneficial ownership was calculated by dividing the number of shares beneficially owned by Benchmark as of January 26, 2011 by 105,329,893 shares (the number of outstanding shares of Common Stock of IET as of October 12, 2010, based upon the Issuer’s Report on Form 10-Q filed with the Securities and Exchange Commission on November 15, 2010).

			Mr. Kinsey beneficially owns 35,017,500 shares of common stock which represents approximately 33.2% of the shares of common stock of IET.

	(b)		Mr. Kinsey has sole power to vote and to dispose of the number of shares set forth on the cover page of this Amendment.

			Benchmark has sole power to vote and to dispose of 0 shares of common stock of IET. The Reporting Persons do not have shared power to vote or dispose of any shares of common stock of IET.

	(c)		Except as set forth or incorporated herein, the Reporting Persons have not effected any transaction in the Common Stock during the past 60 days.

	(d)		Not applicable.

(e)

Benchmark ceased to be the beneficial owner of more than five percent of the shares of common stock of IET on January 21, 2011.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

No modification is made to Item 6 of the Original Schedule 13D.

Item 7. Material to be filed as Exhibits.
