Abstract: A memory chip having a system for controlling sensing time of a data sense amplifier (DSA). A global control is adapted for initiating data access to the memory blocks. A wire path coupling the global control to each memory block is utilized by each memory block as a part of transmitting path for receiving a block enable signal sent from the global control. Specifically, a memory block includes a wired-NOR circuit adapted to send a DSA enable signal to the DSA in response to being selected by a block enable signal. In contrast to a simple delay circuit that only controls the DSA roughly, this wired-NOR circuit tracks internal read signal, and controls the DSA tightly. The time from the activation of the block enable signal by the global control to the enabling of the DSA stays approximately the same irrespective of the memory block's location in the memory chip. Block location independence of DSA sensing time allows tighter memory cycle.

Abstract: A method is provided for retrofitting an existing dead-bolt assembly with an electrically operated actuator (12, 112, 212, 312, 800). The electrically operated actuator automatically operates the dead-bolt assembly while preserving manual operation of the lock. The actuator assembly has rotating means for rotation of the drive bar (18), which in turn extends or retracts the bolt (14) of the lock. The rotating means may be a lever (28, 128, 238, 328, 438, 818) attached to the drive bar (18) that is pivotable about the axis of rotation of the drive bar (18). The actuator assembly has driving means that forces the rotating means to rotate. The driving means is responsive to an electrical signal, which, for example, may be initiated from a remote-controlled transmitter (502, 602). The driving means may include a motor (20, 120, 220) for rotating a rod (22, 122, 222, 322) that in turn operates an assembly that rotates or drives the rotating means.

Abstract: DRAM with column slices improves circuit redundancy. Slices have global column length, and memory is divided in groups with size of redundancy columns having slices. Failure detected among slices of corresponding storage is replaced by corresponding redundancy column slice, such that column redundancy division is in vertical column direction. Column includes global data line shared by column slices and multiple blocks. Redundant column is added to memory array, and redundant control circuits or comparator are proximate to data sense amplifiers. Defective column address are provided to controller through non-volatile memory, or laser-blown or electrically-programmable fuses. When column address is presented, incoming address is compared with stored address, such that select data is output on redundant data line when equal addresses (i.e., hit detect), or normal data is output when unequal addresses (i.e., "miss" detected).

Abstract: A zone cabling termination cabinet of fire-resistant metal, provides a non-plenum enclosed space, close to the work station it serves, recessed into the plenum above a suspended ceiling, for housing communications cable connections and switching, without the need to use high-cost plenum fire-rated materials. The cabinet has an equipment mounting plate removably mounted on the interior surface of an access door, which when closed is flush with the bottom wall of the cabinet, which in turn is flush with the suspended false ceiling. The exposed lower surface of the door is clad with fire resistant ceiling tile material, the utility thereof being two-fold: the cladding makes the cabinet more fire resistant, and visually it blends with the rest of the ceiling, is inconspicuous and not readily detected by the unsuspecting eye, thus providing some measure of security from unauthorized meddling.

Abstract: A key safe having an outer housing for housing a key, a releasable mounting assembly, a releasable opening assembly, an electronic code entry pad, and activation circuitry is disclosed. Alternatively, the outer housing is for housing not a key, but a lever for opening a lock directly. The releasable mounting assembly releasably mounts the outer housing to a mounting surface so that the outer housing may be completely removed from the mounting surface when the releasable mounting assembly is released. The releasable opening assembly permits access to the interior region of the outer housing when the releasable mounting assembly is not released by permitting the outer housing to be moved from a closed position to an open position when the releasable opening assembly is released. The electronic code entry pad is positioned in one or more of the outer housing walls and is exposed to the exterior of the outer housing so that the code entry pad is accessible to a user for entry of a key code.

Abstract: A telephone answering device (TAD) which includes a means of intelligently organizing voice messages, associated entered codes such as personal IDs and home telephone numbers, and information stored in the memory of the TAD. These codes or numbers are decoded by means of the caller entering DTMF signals into the telephone which are recognized, recorded and processed by the TAD. When processed with codes and personal information previously entered into the device's memory, the TAD displays the identity of the callers for each message, thus providing a menu of choices, i.e., a list of callers. This enables the user to access messages in a selective manner based on the identity of the caller. The need to listen to the actual voice messages to determine the caller's identity and the need to listen to the messages sequentially or chronologically is obviated, saving both time and effort.
