A method is provided for inserting a path instruction during compilation of computer programs for a processor having multiple functional resources. A path instruction is inserted in the order of object code instruction during the reordering of the instructions in response to a simulation of the run-time environment of the target machine to direct that the path of execution for a subsequent object code instruction be in accordance with an optimum path of execution for the object code instruction ...

A method for establishing a spoofing service for a high-level file transfer protocol from a modem. A modem spoofing initiation protocol (MSIP) word containing modem limitations is appended to the initial negotiation frame sent by the host to the receiver. If the receiving modem detects the MSIP word at the end of the negotiation frame, it compares its own limits with the received limits, takes the lower limit as the agreement, then appends the agreement word to the frame sent to acknowledge the ...

A method for dynamically changing the polling process of a single microprocessor within a modem. An additional step is added into the main polling loop that checks the amount of data in the transmit and receive buffers. If one buffer is empty, additional polling cycles are performed to service the other buffer. The number of additional cycles is dependent on how full the buffer is. If both buffers contain data, no change is made in the polling process and both are serviced with equal priority.

The present invention discloses a method and apparatus for conductively transferring heat away from electrical devices located on daughter boards attached to mother boards. The preferred method involves the steps of conductively transferring heat from each electrical device to a conductive layer located within the daughter board, transferring heat from the conductive layer within the daughter board to a conductive structure located on the surface of the daughter board, and transferring heat from...

A utility meter reading and communications system gathers data from utility meters and sends that data to a utility company's central data collection point (host computer) via phone lines. The system places a call on the user's telephone line at a specified time and date and transmits data using dual-tone multifrequency (DTMF) format. The system ensures that users still may use the telephone line by sensing off-hook conditions initiated by a resident's telephone and immediately dropping the line...

Utilization circuits, such as logic chip circuits, are prevented from receiving the initial one or more pulses of a train of clock pulses produced after the master system clock is started, while the pulses of that train occurring thereafter are coupled to the utilization circuit. This prevents the skew usually present between the initial pulses of the train relative to the subsequent train pulses from adversely effecting operation of the utilization circuits. This clock swallowing preferably blo...

Four clusters of 16 CPU's each are each associated with a solid state memory and a main memory. Each CPU is uniquely associated with a channel arbitrator which interconnects the associated CPU to serial ports. Each channel arbitrator is associated with a set of 16 serial channels. Each serial channel is in turn interconnected to a channel adapter which includes software and firmware adapted for interacting with a specific peripheral device. Each channel adapter also has software and firmware whi...

A lumbosacral back support member is releasably secured to the user by a stabilizing belt generally worn over the user's clothes. The stabilizing belt may be inserted into the belt loops on the user's pants, attached to the belt loops, or engaged with the narrow portion of the user's waist. The lumbosacral support member is releasable attached to the stabilizing belt. The user positions the lumbosacral support member around the spine from approximately the sacrum to at least the L3 lumbar verteb...

A method and apparatus for packaging test boards during transport and handling is disclosed. The apparatus is a tray having an outer wall and a bottom surface which at least partially define a protected space; and retaining clips for releasably retaining at least one test board in the protected space. In use, a test board is forced between the clip and bottom surface of the tray, where it is retained through friction.
