Latest Patents
One of Khashayar's latest patents involves keyboard testing methods and apparatus. This invention provides an IBM PC compatible keyboard that does not access the keyboard LEDs upon power-up until it receives a command from the host computer. During the Basic Assurance Test (BAT) performed by the keyboard controller on power-up, the LEDs remain off until a host command is received. Upon receiving a Reset command, the controller activates the LEDs and performs a BAT with the LEDs on, ensuring compatibility with IBM PCs. Additionally, the invention features a non-destructive test of the controller RAM during BATs, checking for both 'stuck-at-1' and 'stuck-at-0' conditions. The controller also determines the state of the keyboard LEDs without reading a hardware port, using flags in the controller memory to track the LED state.
