Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
167 words
A processing module comprising: a. at least one processing board comprising a plurality of processing elements each processing element comprising: i. at least one signal receiver for receiving an incoming signal to said processing element; ii. at least one signal transmitter for transmitting an outgoing signal from said processing element; iii. at least one digital micromirror device to provide intraboard and interboard communication with other processing elements; b. at least one computer generated hologram board which, in conjunction with said digital micromirror device, directs said outgoing signal and said incoming signal to and from other processing elements; c. at least one extension board which, in conjunction with said digital micromirror device and said computer generated hologram board, provides interboard communication between said processing element on said processing board and other processing elements on other processing boards; and d. at least one clear spot on said computer generated hologram board which allows said incoming signal and said outgoing signal from said processing element to reach said extension board.
Claim 2
Dependent Claim
167 words
A processing module comprising: a. at least one processing board comprising a plurality of processing elements each processing element comprising: i. at least one signal receiver for receiving an incoming signal to said processing element; ii. at least one signal transmitter for transmitting an outgoing signal from said processing element; iii. at least one digital micromirror device to provide intraboard and interboard communication with other processing elements; b. at least one computer generated hologram board which, in conjunction with said digital micromirror device, directs said outgoing signal and said incoming signal to and from other processing elements; c. at least one extension board which, in conjunction with said digital micromirror device and said computer generated hologram board, provides interboard communication between said processing element on said processing board and other processing elements on other processing boards; and d. at least one clear spot on said computer generated hologram board which allows said incoming signal and said outgoing signal from said processing element to reach said extension board.
