Inventor: GIBSON GARNET FREDERIC RANDALL
IPC: G11C8/16
Filed: 1996-05-15
Abstract: A multi-port RAM (random access memory) including  an  array of RAM cells.  Each RAM cell has a core cell with a single-ended, pseudo-differential write access port and differential, indirect access read ports.  The architecture  of the features of the multi-port RAM allows direct scaling of thenumber of write and read access ports to any practical limit with no adverse effects on cell stability margins and therefore data integrity.  Also, disclosed is a  design detail for an innovative time multiplexed read port architecture implemented as part of a high-speed 9-port time slot interchange random access memory.  It provides a practical, high-speed, low-power and area efficient read port structure to allow eight random access reads per clock cycle. Because all timing is internally generated from a single rising clock transitionof a system clock signal, no special control or clocking is required externally to the memory.

Title: Clutch control for roller shades
Inventor: RUDE EDWARD T
IPC: E06B9/60
Filed: 1995-05-01
Abstract: A spring clutch mechanism (5) for the operation of roller shades (1) and other rollable items. This clutch mech-anism (5) is designed to release for rais-ing the shade (1) so as to minimize effort. Whereas prior art clutch mechanisms for roller shades are intended not to slip, or to slip only to save themselves, in this case, lowering of the shade is accom-plished by overriding the clutch, caus-ing it to slip. The clutch (5) can be adapted easily to accommodate known shade (1) weights. The inventive de-sign provides superior operating charac-teristics and, because the clutch (5) can be built with as few as two parts, much lower cost.
