Title: Method and apparatus for controlling stages of a multi-stage circuit
Inventor: BAZARJANI SEYFOLLAH
IPC: H03M3/02
Filed: 2001-10-31
Abstract: A control mechanism that can be used to control a .SIGMA..DELTA. to provide the required level of performance while reducing power consumption. The .SIGMA..DELTA. ADC is designe dwith multiple stage (i.e., loops or sections), and provides improved performance (e.g., higher dynamic range) as more stages are enabled. The control mechanism selectively enables a sufficient number of stages to provide the required performance and disables remaining stages to conserve power. The control mechanism achieves this by measuring one or more characteristics (e.g., signal level) of the ADC input signal through a .SIGMA..DELTA. ADC that is similar to the .SIGMA..DELTA. ADC on the signal path, comparing the measured characteristic(s) to particular threshold level(s), and controlling the stages such that the desired objectives are achieved. In one implementation, the control circuit includes one or more detector stages, a conditioning circuit, and a signal processor. The detector stage(s) receive the input signal and provide a detected signal. The conditioning circuit receives the detected signal and provides conditined samples. The signal processor receives the conditioned samples and provides a control signal that selectively disables zero or more .SIGMA..DELTA. stages in the .SIGMA..DELTA. ADC.

Abstract: L'invention concerne un appareil à écoulement continu amélioré par ultrasons permettant de mocroémulsionner sélectivement de l'eau et d'autres fluides normalement immiscibles dans le combustible de chambres de combustion continue, au niveau dun point d'injection; et son procédé. Ledit appareil comprend un logement d'injecteur qui définit en partie une chambre conçue pour recevoir un liquide sous pression, et des moyens d'application d'énergie ultrasonore à une partie dudit liquide sous pression. Le logement d'injecteur comprend une entrée conçue pour alimenter la chambre en liquide sous pression, et un orifice de sortie défini par les parois d'une extrémité de l'injecteur. L'orifice de sortie est conçu pour recevoir le liquide sous pression provenant de la chambre via une cavité vestibulaire, et pour faire sortir le liquide de l'injecteur sous forme d'une plume émulsifiée, atomisée. Lorsqu'on excite les moyens d'application d'énergie ultrasonore, ces moyens appliquent ladite énergie ultrasonore au liquide sous pression sans faire vibrer mécaniquement l'extrémité de l'injecteur. Le procédé consiste à fournir un liquide sous pression à l'appareil précité, à appliquer l'énergie ultrasonore au liquide sous pression tout en ne faisant pas vibrer mécaniquement l'extrémité de l'injecteur, l'orifice de sortie recevant le liquide sous pression de la chambre, et faire sortir le liquide sous pression de l'orifice de sortie dans l'extrémité de l'injecteur.

Abstract: Briefly, the present invention provides a dynamic channel re-assignment capability between mobile units (70), base stations (10) and sectors (1, 2, 3, 4, 5) within base station coverage areas (20). The wireless devices used in the present invention may include impulse radio communication devices such as, for example ultra-wideband radio (also known as digital pulse wireless) communication devices. Ultra-wideband bandwidth and channel allocation can be effectively managed, even though link quality generally deteriorates near the outer boundary of the base station. By maintaining dual communications with an adjoining base station, the present invention reduces the bit error rate and maintains signal strength (e.g., RF signal strength). This procedure is termed a "soft-handoff".

Inventor: KOCH THOMAS G
IPC: E01H5/06
Filed: 2003-07-10
Abstract: An improved snow plow for use with light and medium duty trucks is disclosed which has a frame which uses an in-line design to eliminate the presence of rotational or torsional force in the frame members of the snow plow, which design provides an improved degree of ground clearance as well. The snow plow frame design supports the swing frame from both the top and the bottom thereof, while also providing an increased level of rigidity and structural integrity. The snow plow frame and the swing frame are thus both located in the same horizontal axis, so that the predominant line of force through each is from the front of the snow plow to the back.

Abstract: A method of depositing a slug of striped food material comprises sucking a plurality of independent flows of different viscous fluid food (different in colour and/or composition) material into a cylinder (7) of a depositor assembly through respective circumferentially-spaced inlets (16) to the cylinder, preventing reverse flow through said inlets, and then urging the resulting charge of material in the cylinder out of the cylinder through a common outlet (9) so as to extrude the charge into a slug. A plurality of supply passages (11, 12, 13, 14) for the different viscous fluid food materi al connects respective reservoirs (2, 3, 4, 5) for the food materials to the respective cylinder inlet ports (16), a piston (15) being reciprocable in th e cylinder, and piston drive means reciprocating the piston. An outlet valve (10') controls flow through the outlet port (9), and inlet valve means (15') controls flow through the inlet ports. The outlet valve can be a one-way val ve (10'), and the inlet valve means can be constituted by an edge (15') on the piston (15) which is so arranged as to uncover the inlet ports (16) as the piston approaches a fully retracted position. Some blending of the adjacent streams where they contact one another in the cylinder can produce intermediate stripes of material inthe deposited slug.
