Title: Cache memory exchange protocol
Inventor: SMELSER DONALD
IPC: G06F12/08
Filed: 1991-05-14
Granted: 1995-11-21
Abstract: A cache memory exchange protocol that utilizes an exchange memory access request is provided.  A cache controller issues the exchange request over a system bus to a main memory in response to a cache miss if the cache location is dirty.  Upon receiving the request, the main memory decodes the request and fetches a block of information desired by the CPU.  While the main memory is fetching, the controller transfers a dirty cache block of information over the system bus and stores the dirty block in a temporary register located in the main memory.  The block of information desired by the CPU is thereafter trans-ferred by the main memory to the CPU via the system bus.  The dirty cache block residing in the temporary register is then stored in the main memory storage elements.

Title: Insertion/extraction mechanism for blind pluggable modules
Inventor: FERCHAU JOERG U
IPC: H01R13/629
Filed: 1990-01-10
Granted: 1992-07-14
Abstract: (57) Abstract An insertion/extraction mechanism (2) is used to cause blind mateable electrical connectors (10) on an electrical module (4) to engage and disengage mating electrical connectors (12) in a housing (6) by forcing the module (4) to and from its fully in-serted position within the housing (6). The mechanism includes a U-shaped handle (14) pivotally mounted to the module at its ends through elastomeric sleeves (30). The sleeves (30) are each mounted in a mounting hole (32) in the module (4) and each has a central bore (38) within which mounting shaft (40), extending from the handle, is housed. Each end of the handle (14) has a camming surface (54) which engages a pivot pin (16) carried by the housing as the handle (14) is pivoted while inserting the mo-dule (4) into and withdrawing the module from the housing. This engagement of the camming surfaces (54) and the pivot pins (16) causes the handle ends and the associated mounting shafts to push radially against the elastomeric sleeves (30) as the handle is pivoted during insertion and extraction. The elastomeric sleeves (30) both support the mounting shafts and provide the desired biasing force to help keep the module (4) fully inserted within the housing (6).

Title: Two-phase brushless dc motor controller
Inventor: KRUSE DAVID L
IPC: H02P6/08
Filed: 1992-05-27
Granted: 2001-02-27
Abstract: Control circuits for operating a two-phase brushless do motor from a do power source are described. Control of the motor is optimized by detecting induced back EMS of the two phases to sense rotor phase position. It is common knowledge that the voltage developed across the terminals of a permanent magnet motor can be represented by a winding resistance, a winding inductance and a generated back EMF. In two-phase brushless do and permanent magnet stepping motors, the induced back EMFs of the two phases are displaced from each other by 90 electrical degrees. Thus, by detecting the back EMFs of the two phases, an accurate relative position of rotor-to-stator can be determined at any rotor position. Commutation of the motor phases and closed loop control of the motor and load is achieved by accurately sensing the back EMFs of the two phases. Also, phase position of the permanent magnet rotor poles is detected by integrating the sensed back EMFs of the two phases to produce quadrature sinewaves the magnitudes of which are constant relative, to rotor speed.
