Title: Circuit and method of handling asynchronous overspeed
Inventor: RENNER ROBERT E
IPC: H04M11/00
Filed: 1991-09-19
Abstract: A CIRCUIT AND METHOD OF HANDLING ASYNCHRONOUS OVERSPEED                  ABSTRACT There is disclosed a circuit which compensates for a data transmission speed difference between a local asyn-chronous terminal and a local data adapter.  A remote asynchronous terminal is connected to a remote data adapter, the local data adapter is connected to the re-mote data adapter through a telephone system.  The local asynchronous terminal transmits local data to the local data adapter, the local data contains a start element a plurality of data elements, and at least one stop ele-ment.  The remote asynchronous terminal receives from the remote data adapter a remote data where the remote data contains the plurality of data elements from the local data.  The circuit includes a local serial interface ar-ranged to receive the local data from the local asyn-chronous terminal and remove the start element and the at least one stop element from the local data leaving only the plurality of data elements.  A local controller re-ceives the plurality of data elements from the local serial interface and replaces the start element.  The local controller next creates a packet using the start element and the plurality of data elements.  A remote controller receives and disassembles the packet.  Next, a data extractor extracts only the plurality of data ele-ments.  A remote serial interface receives the plurality of data elements from data extractor and replaces the start element and adds a shortened stop element to the plurality of data elements to create the remote data. Finally, the remote serial interface transmits the remote data to the remote asynchronous terminal.

Title: Apparatus and method for a synchronous, high speed, packet-switched bus
Inventor: SINDHU PRADEEP S
IPC: G06F13/364
Filed: 1991-12-30
Abstract: A high speed, synchronous, packet-switched inter-chip bus apparatus and method for transferring data between multiple system buses and a cache controller. In the preferred embodiment, the bus connects a cache controller client within the external cache of a processor to a plurality of bus watcher clients, each of which is coupled to a separate system bus. The bus allows the cache controller to provide independent processor-side access to the cache and allows the bus watchers to handle functions related to bus-snooping. An arbiter is employed to allow the bus to be multiplexed between the bus watchers and cache controller . Flow control mechanisms are also employed to ensure that queues receiving packets or arbitration requests over the bus never overflow. A default grantee mechanism is employed to minimize the arbitration latency due to a request for the bus when the bus is idle.

Inventor: PYZIK THOMAS E
IPC: G01F1/06
Filed: 1992-01-06
Abstract: An assembly for accurately and easily positioning and aligning a sensor device relative to a fluid flow stream in a pipe, incorpo-rates a threaded housing which is engageable with a standard  pipe tee-fitting to provide a platform for linearly positioning the sensor relative to the axis of flow.  A sensor unit subassembly is rotatably supported on the platform so that it may be rotated into proper radial alignment with the flow axis while it is supported on the platform at the proper linear position relative to the flow axis. A paddlewheel flowmeter having a single leg supporting the paddlewheel axle in cantilever fashion forms the sensing unit which exploits the improved alignment accuracy of this assembly to avoid build-up of sludge and debris which might affect free rotation of the paddlewheel.   Separate  and independent lock-nuts  fix the housing in position relative to the tee-fitting, and fix the sensor sub-assembly in position relative to the housing.

Title: Universal processing module for programmable radio's
Inventor: THOMPSON DEAN A
IPC: H04L27/01
Filed: 1992-07-08
Abstract: Abstract of the Disclosure The universal signal processing apparatus provides signal processing for radios using generic software modules stored in a nonvolatile memory, a microcomputing device that controls a programmable digital signal processing device, an analog to digital converter and a digital to analog converter. A radio processor communicates with the microcomputing device and requests the type of signal processing required. To provide flexibility, the radio processor and the microcomputing device have their programs stored in an EEPROM. When the radio processor requests a type of signal processing, the microcomputing device retrieves its programming from a designated location within the EEPROM. Based on the retrieved instructions, the microcomputing device programs the digital signal processing device to access specific generic softeware modules. The microcomputing device then controls the signal processing by controlling the analog to digital converter, the digital to analogconverter and the data flow into and out of the digital signal processing device.
