IPC: E05B65/12
Filed: 2000-03-03
Abstract: A modular latch assembly having at least one control element having one path of motion in which a ratchet is moved to an unlatched position and another path of motion in which the ratchet is not so moved, the path of motion taken by the control element dependent upon whether an engagement element is extended into engagement with the control element or retracted from engagement therewith. Preferably, the control element moves the ratchet by contact with a pawl which itself can be engaged with the ratchet.  A manual override can be installed for manually shifting an engagement element into and out of engagement with a control element to place the control element in latched and unlatched states as desired. The latch assembly is preferably provided with a number of different control element positions for receiving control elements therein, each of which is actuatable to move the pawl when in an unlocked slate. The number of control elements selected, their selected positions in the latch assembly, and their connection arrangement to input elements are highly flexible, providing latch adaptability to a large number of applications and latch functionalities. The latch assembly preferably has elements arranged and assembled in layers to increase assembly ease and speed. A highly preferred embodiment of the invention includes an automatic unlocking circuit powered by a backup power source.

Title: Multiprocessor computer architecture incorporating a plurality of memory algorithm processors in the memory subsystem
Inventor: LESKAR PAUL A
IPC: G06F15/80
Filed: 1998-12-03
Abstract: A multiprocessor computer architecture incorporating a plurality of programmable hardware memory algorithm processors ("MAP") in the memory subsystem. The MAP may comprise one or more field programmable gate arrays ("FPGAs") which function to perform identified algorithms in conjunction with, and titly coupled to, a microprocessor and each MAP is globally accessible by all of the system processors for the purpose of executing user definable algorithms. A circuit within the MAP signals when the last operand has completed its flow thereby allowing a given process to be interrupted and thereafter restarted. Through the use of read only memory ("ROM") located adjacent the FPGA, a user program may use a single command to select one of several possible pre-loaded algorithms thereby decreasing system reconfiguration time. A computer system memory structure MAP disclosed herein may function in normal or direct memory access ("DMA") modes of operation and, in the latter mode, one device may feed results directly to another thereby allowing pipelining or parallelizing execution of a user defined algorithm. The system of the present invention also provides a user programmable performance monitoring capability and utilizes parallelizer software to automatically detect parallel regions of user applications containing algorithms that can be executed in the programmable hardware.

Abstract: A mechanical neck rest retraction device with a memory function including a movably supported locking member which is designed to yieldingly be brought into engagement with one of several stop notches of a neck rest rod. A bridge member is designed to be connected to the ends of the two neck rest rods and a detent member biased by a first spring, is movably supported on the bridge member. An elongate actuator adapted to be moved in parallel with the axis of the neck rest rods, which actuator is engaged by an actuating rope which, when actuated, pulls the actuator downwards against a second spring which biases the actuator upwards. A series of detent recesses are on the elongate actuator for the detent member, which recesses extends in the longitudinal direction of the actuator and having a spacing which corresponds to the spacing of the stop notches, the detent member being located between two adjoining detent recesses when the locking member is in engagement with a stop notch. A stationary guide interacts with the actuator such that when the actuator is in an upper position, the detent member is out of engagement with the actuator, but the actuator is moved towards the detent member from a given displacement path onwards, which causes it to engage the next following upper detent recess. An unlocking member is connected to the actuator, which member actuates the locking member for the release of the neck rest rod when the actuator is moved downwards.
