Equity Method Investments and Joint Ventures [Abstract]
Equity Investments	The Company acquired an equity interest in a company in the first quarter of 2018. The Company made a $1.0 million capital contribution during the three months ended March 31, 2018. The Company also contributed certain intellectual property. As of September 29, 2018, the Company owns 12.5% interest in this investment and the carrying value of the Company's investment is $3.9 million. The Company recorded a $0.3 million unrealized loss in the nine months ended September 29, 2018 in this equity investment due to a fluctuation in the foreign exchange rate. The fair value of this equity investment is approximately $3.6 million. The Company acquired an interest in an equity investment by exercising a warrant to acquire up to 15% of the next round of equity offered by a customer as part of the licensing of technology to the customer. The Company used the customer's capital structure, pricing of the shares being offered and 15% from the customer's qualified financing round in determining the value of its equity investment. The Company recorded an unrealized loss of less than $0.1 million in the nine months ended September 29, 2018 in this equity investment due to a change in the Company's estimate of the value of the equity investment based on the observable transaction price at the exercise date of the warrant. The fair value of this equity investment is approximately $1.9 million. The Company adopted the measurement alternative for equity investments without readily determinable fair values (often referred to as cost method investments) on a prospective basis. As a result, these investments will be revalued upon occurrence of an observable price change for similar investments and for impairments. The Company did not have an observable price change for similar investments of its equity investments and recorded no impairments on its equity investments during the three months ended September 29, 2018.
