Revenue from Contract with Customer [Abstract]  
Revenue from Contract with Customer [Text Block] Revenue Recognition and Deferred Revenue
The Company records revenue based on a five-step model in accordance with ASC Topic 606, Revenue From Contracts With Customers (“ASC 606"). The Company's revenue is derived from the sale of products, software, and services identified in contracts. A contract exists when both parties have an approved agreement that creates enforceable rights and obligations, identifies performance obligations and payment terms and has commercial substance. The Company records revenue from these contracts when control of the products or services transfer to the customer. The amount of revenue to be recognized is based upon the consideration, including the impact of any variable consideration, that the Company expects to be entitled to receive in exchange for these products and services.
