Title: Time-division multidirectional multiplex communication system capable of using message area in radio burst signals divided into a plurality of areas
Inventor: KIMURA ATSUSHI
IPC: H04Q11/04
Filed: 1995-08-28
Granted: 1999-12-14
Abstract: A master station and at least one slave stations are connected by radio channels, and each slave station transmits data to the master station by time division multiple access.  First means equally divides a prescribed area, which is defined in a burst signal for use in transmission from each slave station to the master station and intended for arrangement of message signals sent from at least one terminal connected to the slave station, into at least two sub-areas, and arranges a message signal in each sub-area.  Second means generates a burst signal, in which at least a control signal and a channel quality monitoring signal are arranged, in the area peripheral to each sub-area in which a message signal is arranged.  Here the prescribed area in the burst signal is an area corresponding to a data quantity of 64 kbps in transmission speed.  The data quantity of the message signal arranged in that area corresponds to data of 32 kbps, 16 kbps or 8 kbps in transmission speed.
Patent CA-2162168-C (CA)
Title: Opto-electric-mechanical device or filter, process for making, and sensors made therefrom
Inventor: GUCKEL HENRY
IPC: H01L31/00
Filed: 1994-05-25
Granted: 2005-03-22
Abstract: This invention relates to devices and their applications which employ a resonant semiconductor member whose vibratory motion is coupled to the radiant energy cast onto a photovoltaic energy conversion device. It also relates to such devices whose vibratory behaviour is otherwise affected and which affect can be read optically. Optical methods are used to drive die microbeam, sense the microbeam vibrations and, if certain conditions are met, produce self-oscillation with no intervening electro-optical components, thus eliminating the need for piezoresistors, drive electrodes, electrical contacts and any metallurgy for electrical interconnection. A resonant microstructure member of one electrical type (p or n) is formed over a wafer, this member extending substantially or fully over a cavity or other space in the wafer. At a location in a wall or floor of the cavity is a region of opposite type (p or n) material. The interface between the two types is a p-n junction and is the best known form of a photovoltaic structure. The flexible member and the opposite type region should be substantially in the path of the driving radiant energy. The devices of this invention act as opto-electro-mechanically coupled photodiodes-causing the flexible member to be attracted electrostatically to the opposite type region by the incident driving light. The close proximity of the flexible member to the substrate or to an integrated cover or top cap forms a Fabry-Perot interferometer capable of producing large intensity modulations of the reflected light with small displacements of the member. A preferred form would have the vibratory member located within an evacuated capsule. The top cap would seal the member off on one side, and the wafer on which it was mounted or formed would seal the other. Applications as pressure sensor, accelerometer, acoustic ranger apparatus and temperature sensitive apparatus.

Abstract: A multicolor optical image-generating device comprised of an array of grating light valves (GLVs) organized to form light-modulating pixel units for spatially modulating incident rays of light. The pixel units are comprised of three subpixel components each including a plurality of elongated, equally spaced apart reflective grating elements arranged parallel to each other with their light-reflective surfaces also parallel to each other. Each subpixel component includes means for supporting the grating elements in relation to one another, and means for moving alternate elements relative to the other elements and between a first configuration wherein the component acts to reflect incident rays of light as a plane mirror, and a second configuration wherein the component diffracts the incident rays of light as they are reflected from the grating elements. The three subpixel components of each pixel unit are designed such that when red, green and blue light sources are trained on the array, colored light diffracted by particular subpixel components operating in the second configuration will be directed through a viewing aperture, and light simply reflected from particular subpixel components operating in the first configuration will not be directed through the viewing aperture.
