Abstract: A system and method for locating objects such as people, pets, and personal articles is described. A transceiver is attached to the person, animal, or item to be tracked and a handheld locator device is employed to transmit a locator signal containing an address code to the transceiver. Upon receipt of a signal, the transceiver compares the address code contained in the locator signal with an address code stored in the transceiver. If the two codes are same, the transceiver sends a return signal back to the locator device. The locator device uses this return signal to determine the distance and/or direction of the transceiver from the user's location. The system allows a user to select from a multiple number of items to locate and allows multiple users to search for different articles within the same general area without interference.

Abstract: Fully dense composite accurate tooling is manufactured by casting but without the requirement of subsequent machining. The tooling so provided by the invention comprises injection mold halves for mating engagement to form a mold for injecting multiple near net shapes using either thermoset or thermoplastic materials. A known vacuum casting technique used for producing parts has been modified to make tooling according to the invention. A master pattern of the near net shape or a model of the actual core and cavity of the desired mold is used to create a silicone rubber mold (SRM). Once the SRM is completed, the 3-part material (catalyst, resin and composite) is weighed to the required volume to cast into the SRM, then placed (along with the SRM) into the vacuum casting system which reaches a level of 28 inches Hg of vacuum. The 3-part composite material is thoroughly mixed for approximately 20 minutes in about 28 inches Hg of vacuum.

Abstract: A self-adapting interface assembly on a data processor allows communication with a variety of other data processing devices operating under different communication protocols. The assembly comprises an input and output signal translating module installed between the data processor input/output port and a cable terminated by simple adaptor modules for coupling to various types of data processing devices. The adaptor can sense the type of device and send to the translating module an identifying bit stream. The translating module uses the device identification to programmatically change the configuration of data receivers and drivers and control signal buffers in order to assure exchange of data between the data processor and the device connected to the adaptor module regardless of their respective electrical interface characteristics.

Abstract: In the operation of a network of data processing units, a method and apparatus for transferring information between units in a multi-processor environment at high throughput rates.The high throughput rates are achieved by concurrent send/receive direct-memory-access transfers between buffer memories associated with each unit. The invention provides for direct-memory-access (DMA) transfers between a buffer memory and the data port of the sending unit and direct-memory-access transfers between this data port and the buffer memory of the receiving unit; thus eliminating shared-memory resource allocation, memory access arbitration and other programmed operations which normally require execution of several instructions by each unit's processor for each transfer.

Abstract: A thermocouple simulator system which is capable of generating a voltage equivalent to the EMF output of a thermocouple of a selected type at a specified sensing junction temperature. The system includes a keyboard which allows an operator to specify a sensing junction temperature, voltage, thermocouple type, reference junction temperature, and whether a pair of output terminals of the system perform as thermocouple alloy or copper. Using an operation program, a microprocessor calculates the thermocouple EMF using a stored temperature versus EMF polynomial function of the selected thermocouple type. The microprocessor then causes a voltage simulating the calculated EMF to be applied to the output terminals utilizing a reference voltage source, digital-to-analog converter (DAC), and output amplifier.
