Surround Sound Driver Architecture with Multiple Sound Cards. 1994. US Patent 5,630,175 (PDF) – May 13, 1997, Surround Sound System. Canadian Patent 2,132,763 – March 30, 1999.
A stereo computer system with resources to produce and record surround sound channels. Such surround sound channels are played or recorded using an audio card added to the computer system, which audio card controls additional speakers and/or microphones. Software for redirecting instructions from existing stereo application programs and sending these instructions to the existing audio device driver and the additional audio device driver is provided. Resources for processing the digital audio data for either extracting surround sound channels from two channel data provided by the application, or for encoding two sets of two channel audio data recorded by the two audio cards is also included.

Dual Mode Collimated Communications Transceiver. 1996. Canadian Patent 2,194,024. – January 30, 2001.
The invention provides an optical communications system having a dual mode of operation. It includes a communications module having an optically active portion with a wide-angle view; a light collimator; and a connector connecting the communications module and the light collimator to permit the module and collimator to be selectively positioned in a collimated or non-collimated position. When it is in the collimated position, the communications module is positioned at the focal point of the collimator, and, when in a non-collimated position the communications module is positioned away from the focal point of the collimator; so that the communications system has a narrow field of view when operated in the collimated position, and has a wide field of view when operated in the non-collimated position.

Multi-simulator Co-simulation. 1999. US Patent 6,560,572 (PDF) – May 6, 2003.
A mixed-mode simulator for simulating a circuit containing an event-driven device with a plurality of pins. The mixed-mode simulator has a circuit simulator for simulating at least an analog portion of the circuit. The circuit simulator has a user-defined device modeling feature. The mixed-mode simulator has an event-driven device simulator and an interface between the circuit simulator and the event-driven device simulator. The interface has a parameter passing portion for receiving values from and returning values to the circuit simulator through the user-defined device modeling feature. The interface has a timing portion for instructing the event-driven simulator to run a simulation of the device based on the values for a given time period. The interface has a response reading portion for reading values of the pins at the end of the time period. Values are returned to the circuit simulator through the parameter passing portion and the user-defined modeling feature.
