Patent CA-2044774-A1 (CA)
Inventor: OGINO TOORU
IPC: H04B7/26
Filed: 1991-06-17
Abstract: A receiver mounted on an automobile telephone or similar mobile station which is included in a cellular mobile radio communication system. The receiver has a high frequency amplifier for amplifying a received input wave, and a mixer for converting the received input wave to an intermediate frequency. The gain of the amplifier or that of the mixer is changed on the basis of the level of the field strength of the received input wave and whether or not the mobile station is communicating with a base station. The receiver enhances the reception sensitivity characteristic at locations where the reception field strength is low or the intermodulation distortion characteristic at locations where the field strength is high and intermodulation distortions occur.

Filed: 1992-02-12
Abstract: A circuit for enabling the raster display of text or line art in one constant color against a background of another constant color or against a continuous-tone picture, or the display of a continuous-tone picture through an arbitrary shape. The circuit has four channels, one each for constant colors, continuous-tone images, image masks, and instructions. The constant colors are stored in the first channel in the form of two 8-bit colors, one for the text or line art and one for the background. Any color pair can be read from this memory, divided into two 8-bit colors, and presented at two inputs of a final multiplexer. The second channel stores continuous tone color pictures and presents this information at a third input of the multiplexer. The third channel receives masks or outlines in the form of bitmaps and the fourth channel receives instructions which may be run-length encoded. These two channels combine their data, which is then used to control the multiplexes.

Abstract: A microcircuit bias-current supply (10) in a wristwatch-pager (12). An FM-radio receiver in a microcircuit paging device operates intermittently with a short on-time and long off-time to reduce power consumption and preserve battery life. The bias-supply circuit (10) distributes predetermined bias currents to a plurality of functional circuit areas (12) of the microcircuit die, the bias currents being disabled during off-time of the receiver such that the current drain of the entire microcircuit is virtually zero, being in the range of nanoamps. The inefficiencies and disadvantages of a series switch power on and off are eliminated by providing a plurality of switched current sources (44a-44n) which perform the dual function of circuit biasing and current switching.

Abstract: Erythrocytes exist in vivo in a continuous cell subset gradient of density, with the youngest cells being the lightest. A blood sample is centrifuged in a transparent tube containing plastic beads which are selected to include groups of beads wherein each group has a different sharply defined specific gravity, and which are distributed within the range of red cell  densities. The  beads form spaced  narrow bands in the erythrocyte layer, which bands form boundries between the different cell subset layers. Measurements of the lengths of the different  cell subset layers  are then made to quantify the red cell subsets in the patient's blood.

Abstract: The invention relates to a shower control valve assembly which includes a casing mountable in a wall with inlets for hot and cold water. A cartridge is insertable into the casing in one of two orientations so that the hot water inlet of the cartridge can be aligned with either one of the casing inlets, depending on which one is the hot water inlet. The casing has two outlets, one for the shower and the other for the tub. There is an integral bypass which takes water from the tub outlet to the shower outlet upon activation of a diverter valve. The cartridge is of the pressure and temperature balancing type, with water of the desired temperature flowing to the tub outlet and then to the tub or shower as desired. Each water inlet in the cartridge includes a check valve which, in one position allows water to enter the cartridge, and in the other position prevents water from leaving the cartridge through the inlet. This feature prevents cross flow of hot and cold water, prevents back flow into the supply pipes and, most significantly, prevents water hammer in the supply pipes.
