Other Commitments, Description			In April 2013, we entered into an agreement with an Eco-System Partner (the "Agreement"), whereby we will receive $10 million of cash proceeds to assist us in increasing our production capacity. The Agreement requires us to have the capability to produce at least 1 million sensor units per month (as defined in the Agreement) by April 2014. Upon achieving the minimum production capability and meeting the required quality standards specified in the Agreement, we will record non-recurring engineering revenue for the total amount of cash proceeds received. As of June 30, 2013, we have received $5 million, which is recorded as deferred revenue in the accompanying balance sheet. Upon achieving the deliverables of the Agreement, we will pay a commission to the Eco-System Partner of 10%, on revenue derived from the sales of UniBoss sensors directly to the Eco-System Partner or to those of the Eco-System Partner's manufacturing partners that use the Eco-System Partner's Preferred Price and Capacity License Agreement.The commission amount is capped at $18.5 million.
