Title: On-board weighing system for a vehicle
Inventor: TYHY GARY
IPC: G01G19/12
Filed: 1992-02-12
Granted: 1995-08-22
Abstract: An on-board weigh scale for a vehicle is disclosed. The weigh scale has a transport configuration wherein the weigh scale is substantially protected from damage during transport, and a weighing configuration wherein the weigh scale is in an operative condition for measuring the weight of a material.   The weigh scale includes a support-frame capable of being mounted on a frame of a vehicle; a weigh-frame  mounted  above  the  support-frame,  and  capable of supporting a quantity of a material.  Structural supports are mounted on the support-frame for securely supporting the weigh-frame in the transport configuration.  Hydraulic jacks are used to lift the weigh-frame off of the structural supports when said weigh scale is in transition between the transport and the weighing configurations.   The weight of material is detected by load cells, via load transfer elements which are installed when the weigh scale is in the weighing configuration.  The load transfer elements are removed in the transport configuration, in which condition, the load cells are not subject to any of the weight of the material.  Finally angle sensors are used to detecting the angle of orientation of weigh scale with respect to vertical.  The detected angle is used to determine a calibration signal, thus allowing for compensation of an error in the weight detected by the load cells resulting from an out-of level condition of the weigh scale, thereby facilitating accurate weight measurements.

Title: Multi-media signal processor computer system
Inventor: CARMON DONALD EDWARD
IPC: G06F17/10
Filed: 1992-05-27
Granted: 1999-11-30
Abstract: A multi-media user task ghost, computer is interfaced to a high speed DSP Which provides support functions to the host computer via an interprocessor DMA bus master and controller. Support of multiple dynamic hard real-time signal processing task requirements are met by posting signal processor support task requests from the host processor through the interprocessor DMA controller to the signal processor and its operating system. The signal processor builds data transfer packet request execution lists in a partitioned queue in its own memory and executes internal signal processor tasks invoked by users at the host system by extracting signal sample data from incoming data packets presented by the interprocessor DMA controller in response to its execution of the DMA packet transfer request queues built by the signal processor in the partitioned queue. Processed signal values etc. are extracted from signal processor memory by the DMA interprocessor controller executing the partitioned packet request lists and delivered to the host processor. A very large number of packet transfers in support of numerous user tasks and implementing a very large number of DMA channels is thus made possible while avoiding the need for arbitration between the channels on the part of the signal processor or the host processor.

Granted: 1998-12-29
Abstract: A block of output symbols is generated, using quadrature amplitude modulation, from a block of input bits. The input bits are processed, using one or more redundant codes having a Hamming distance greater than one, to produce digital words which control the in-phase components and digital words which control the quadrature components of the output symbols. A group of bits generated by a single coding step supplies bits for both types of digital word, thereby enabling that coding step to process simultaneously a larger number of bits than would be the case if separate coding were used for producing the two types of word.
