Patent CA-2132986-A1 (CA)
Title: Semiconductor optical devices and techniques
Inventor: HOLONYAK NICK JR
IPC: H01S5/00
Filed: 1993-03-26
Abstract: The disclosure is directed to improved techniques and devices employing an aluminum-bearing III-V  semi-conductor material and a native oxide of aluminum that is formed in the semiconductor material. In a form of the disclosure, two linear arrays of end-coupled minicavities, defined by a native oxide of an aluminum-bearing III-V semiconductor material, are arranged side by side to obtain a two dimensional array, with resultant lateral coupling between the linear arrays. The two dimensional array exhibits mode switching and multiple switching in the light power (L) versus current (I) characteristic (L-I) with increasing current. In another form of the disclosure, a stripe laser (1210) is transversely coupled (or side-coupled) with a linear array of end-coupled minicavities (1221-1275). Bistability and switching are demonstrated in the light versus current (L-I) characteristic of a native-oxide-defined structure of this type.
Patent CA-2136364-A1 (CA)
Title: Method of controlling multiple processes using finite state machines
Inventor: SCHELL WILLIAM M
IPC: H04N21/239
Filed: 1994-11-22
Abstract: A method of using finite state machines (FSMs) is disclosed for controlling multiple processes in response to input signals. In an exemplary embodiment, such processes comprise facilities for providing interactive television services and multimedia signals for such services. The FSMs are arranged in a tree-like structure and communicate with each other by event messages of various types. Each FSM has multiple states and permitted state transitions. Transitions occur in response to event messages and/or input signals, and a transition can cause one or more event messages associated with such transition to be sent. At least one terminal FSM is associated with each of the multiple processes and controls thatprocess. Status changes in each process can also cause state transitions in the FSMs. The FSMs are resident in the various processors controlling the multiple processes, which can be situated at different locations.

Patent CA-2141064-A1 (CA)
Title: Remote switched outlet with learning capability
Inventor: QUACH LUAN C
IPC: H02J13/00
Filed: 1995-06-05
Abstract: In controlling a line-powered device or appliance remotely, it is known to have a product that provides the user a transmitter and a receiver as a married pair. The transmitter is necessary to send to the receiver a signal that is coded in either software or hardware format. The receiver, upon receiving the transmitted signal, will perform the decoding process. If the received signal is valid, the receiver will respond by switching or performing any variation to the line voltage characteristic that is applied to the appliance.   In this invention, the user can control the appliance remotely via an inventive device without the need to supply the user a dedicated transmitter. This device is a receiver that has an intelligent learning capability. The user can utilize any of his/her own home entertainment remote control units with his/her choice of command key to program this device. Once programming is completed, the device will and only will respond to the coded signal transmitted by the same key from the same remote control unit that the device has just learned. Hence, the user can assign different command keys to program multiple devices without any concern of interference or false signal recognition. The concept of having the learning feature built into a device to control line-powered appliances remotely without the need for a dedicated transmitter opens up infinite applications to achieve automation for the household (ie, Remote Switched Outlet, Remote Switched Wall-Switch...) regardless to any types of line voltages in the world (i.e., 110VAC, 220VAC...).

Title: Apparatus and method for efficient transfer of data and events between processes and between processes and drivers in a parallel, fault tolerant message based operating system
Inventor: FISHLER LEONARD R
IPC: G06F11/14
Filed: 1996-01-19
Abstract: A parallel, fault-tolerant computer system in which data is transferred between processes in a single CPU by two methods. In a first method, the data is copied each tune it is transferred. In a second method, the data is not copied, but is passed through a shared memory, queueing system. The first method is used to ensure fault-tolerance and linear expandability. The second method is used to minimize the time required for inter-process communication. Use of the shared memory queueing system allows for faster communication between processes executing in a same CPU.

Title: Non-invasive non-spectrophotometric infrared measurement of blood analyte concentrations
Inventor: BLOCK MYRON J
IPC: G01N21/35
Filed: 1995-01-09
Abstract: A new non-invasive non-spectrophotometric method for measuring the blood concentration of ana-lytes such as glucose has been developed. A plurality of broad spectrum filters (30A-30D) transmit distin-guishably coded by choppers (20A-20D) beams of radiation in overlapping portions of the spectrum to the sample. Radiation reflected or transmitted by the sample is detected and decoded. LED's may be used instead of the broad spectrum radiation generating device and the filters. Further, a scanning interfer-ometer cam be used as the illuminating and coding device. In a preferred mode, congruent illumination is utilized. The coded signals are analyzed by anal-ogy to colorimetry and visual processing and can be converted into concentration measurements.
