Title: Apparatus and method for asynchronously delivering control elements with a pipe interface
Inventor: BONEVENTO FRANCIS MICHAEL
IPC: G06F5/06
Filed: 1990-09-19
Granted: 1998-03-31
Abstract: A microprocessor system which includes a processor unit with system memory and a separate buffer memory, one or more subsystem adapter units with memory, optional I/O devices which may attach to  the  adapters,  and a bus interface.  The memory in the processor and the memory in the adapters are used by the system as a shared memory which is configured as a distributed FIFO circular queue (a pipe).   Unit to unit asynchronous communication is accomplished by placing control  elements on the pipe which   represent   requests,    replies,    and   status information.  The units send and receive control elements independent of the other units which allows free flowing asynchronous delivery of control  information and data between units.   The shared memory can be organized as pipe pairs between each pair of units to  allow full duplex operation by using one pipe for outbound control elements and the other pipe for inbound control elements. The control elements have standard fixed header fields with variable fields following the fixed header.   The fixed header allows a common interface protocol to be used by different hardware adapters.  The combination of the pipe and the common interface protocol allows many different types of hardware adapters to asynchronously communicate, resulting in higher overall throughput due to lower interrupt overhead.

Granted: 2001-01-30
Abstract: A power lead for a cryostat has high temperature superconducting (HTSC) conductors extending inward toward a pool of liquid cryogen in the cryostat in series with normal conductors extending from the HTSC conductors to outside the cryostat. Tubular shrouds vented to atmosphere direct a flow of cryogen vapor along the HTSC conductors to maintain them superconducting, and along the normal conductors to remove Joule heat and heat leakage along the normal conductors. In one embodiment, a pool of liquid nitrogen maintained within a tubular inner shroud is the principal coolant for the normal conductors. Helium vapor is circulated over the HTSC conductors and is then directed by an outer tubular shroud around the inner tubular shroud to provide additional cooling for the normal conductors. Flexible connectors at one end of each of the HTSC conductors accommodate for individual thermal contractions of these conductors.

Abstract: The devices proposed improve low-frequency sound reproduction in loudspeaker systems using acoustically closed loudspeaker housings. In particular, the devices permit the use of loudspeaker housings with very much smaller dimensional volumes but with large-area loudspeakers. The devices proposed operate utilizing pressure control in closed loudspeaker housings. This pressure control decreases differences between the gas pressure in the interior of the housing and the time-averaged mean gas pressure outside the housing. The control circuit comprises a pressure sensor, a control unit, a power amplifier and an electrodynamic transducer.

Abstract: A surgical staple is used in joining the skin or fascia of a patient, and is especially desired to be used with mesh placed over a cut organ, such as the kidney.      The staple is adapted to be formed about a central anvil and former. The configuration of the staple is such that at initial contact the points of the staple are formed at acute angles to the central portion of the staple. In this fashion, upon forming, a modified "B" shape is derived. This configuration has proven useful to reduce rotation of the staple when emplaced over mesh.
