On September 9, 2010, the Company signed a First Loan Modification Agreement relating to the mortgage note, which reduced the annual interest rate from 6.84% to 5.50% and the monthly payment from $76,280 to $69,000.
	On September 26, 2013, the Company signed a Second Loan Modification Agreement relating to the mortgage note, which extended the maturity date from December 23, 2015 to September 26, 2023. The modification also reduced the annual interest rate from 5.50% to 4.43% through September 26, 2018, at which time the interest rate will be adjusted to a per annum fixed rate equal to the aggregate of the Federal Home Loan Board (FHLB) Five Year Classic Advance Rate plus two hundred forty basis points. The current monthly payment was reduced from $69,000 to $57,997. The mortgage note had an outstanding balance on June 29, 2014 of approximately $7.4 million. All outstanding principal and accrued and unpaid interest will be due and payable on the maturity date.
	Letters of Credit

Net Income (Loss) Per Share	'
	(6) Net Income (Loss) Per Share
	Basic earnings per share (EPS) is computed by dividing net income (loss) available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted EPS is computed using the weighted-average number of common shares and potentially dilutive securities outstanding during the period, using the treasury stock method. Potentially dilutive securities include outstanding stock options and unvested restricted stock units (RSUs). Due to their anti-dilutive effect, approximately 1,208,627 and 1,335,721 securities to purchase common stock were excluded from the calculation of diluted loss per share for the three months ended June 29, 2014 and June 30, 2013, respectively. Due to their anti-dilutive effect, approximately 1,409,895 and 1,335,721 securities to purchase common stock were excluded from the calculation of diluted loss per share for the six months ended June 29, 2014 and June 30, 2013, respectively. However, these potentially dilutive securities could become dilutive in future periods.

Accounting for Stock-Based Compensation	'
	(7) Accounting for Stock-Based Compensation
	Stock Options
	The Company accounts for share-based compensation in accordance with the provisions of SFAS No. 123R, Share-Based Payment (now codified as FASB ASC Topic 718, Compensation-Stock Compensation (“ASC 718”)). This statement establishes standards for accounting for transactions in which an entity exchanges its equity instruments for goods or services. The Company’s stock option compensation expense was $121,011 and $245,991 for the three and six months ended June 29, 2014, respectively and $137,764 and $296,957 for the three and six months ended June 30, 2013, respectively. These amounts do not include expense related to restricted stock awards or the employee stock purchase plan.
	The fair value of each option is estimated on the date of grant using the Black-Scholes option-pricing model. This model incorporates certain assumptions for inputs including a risk-free market interest rate, expected dividend yield of the underlying common stock, expected option life and expected volatility in the market value of the underlying common stock. The Company is also required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. Historical data is used to estimate pre-vesting forfeitures and record stock-based compensation expense only for those awards that are expected to vest. Accordingly, awards ultimately expected to vest have been reduced by an annualized estimated forfeiture rate of 4%.
	Calculation of Fair Value - Assumptions Used:	Six months ended
		June 29, 2014			June 30, 2013
	Expected Volatility		64.88	%		66.84	%
	Expected Life (in years)		4.1			4.21
	Risk-Free Interest Rate		1.26	%		0.79	%
	Expected Dividend Yield		—			—
	Expected volatilities are based on the weighted average historical volatility of the Company’s common stock for the expected life of the option. The Company has significant historical data to help evaluate the expected lives of options in developing its assumption. The risk-free interest rate is based upon quoted market yields for United States Treasury debt securities with a term approximating the expected life of the options. The expected dividend yield is based upon the Company’s history of not issuing dividends and management’s current expectation of the same.
	The following table summarizes the stock option activity during the six months ended June 29, 2014:
		Shares			Weighted-			Average		Aggregate
					Average			Remaining		Intrinsic
					Exercise			Contractual		Value
					Price			Term
	Options

	Exercisable at June 29, 2014		1,020,986		$	5.28			2.74	$	174,458
	The weighted-average grant date fair value of options granted during the six-month periods ended June 29, 2014 and June 30, 2013 were $1.44 and $1.21, respectively. The aggregate fair value of options exercised during the six-month periods ended June 29, 2014 and June 30, 2013 was $720 and $0, respectively.
	As of June 29, 2014, there was $376,273 of total unrecognized compensation cost related to non-vested options granted under the Company’s option plans. That cost is expected to be recognized over a weighted-average period of 1.10 years. The total fair value of options vested during the six-month period ended June 29, 2014 was $282,460.
	Restricted Stock Units
	In April 2014, the Company granted 62,725 restricted stock units to various employees. The fair value of the restricted stock units at the date of the grant was $2.95. The Company recorded compensation expense of $56,039 and $15,599 during the six-month period ended June 29, 2014 and June 30, 2013, respectively, related to restricted stock units. As of June 29, 2014, there was $212,001 of unrecognized compensation costs related to grants of restricted stock units and these grants have a remaining life of 1.30 years.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments	'
	(8) Fair Value of Financial Instruments
	In accordance with the requirements of FASB ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”), the Company groups its financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
		•	Level 1 - Valuation is based upon quoted market price for identical instruments traded in active markets.
		•	Level 2 - Valuation is based on quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.
		•	Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market. Valuation techniques include use of discounted cash flow models and similar techniques.
	In accordance with the requirements of ASC 820, it is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. When available, the Company uses quoted market prices to measure fair value. If market prices are not available, the fair value measurement is based on models that use primarily market based parameters including interest rate yield curves, option volatilities and currency rates. In certain cases, where market rate assumptions are not available, the Company is required to make judgments about assumptions market participants would use to estimate the fair value of a financial instrument. Changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values.
	The carrying amounts of the Company’s cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to their short-term nature. Long-term debt is also reported at carrying value and approximates fair value as the interest rate on the mortgage note payable of 4.43% approximates the current market interest rate.
