To provide another way to exit and/or enter an elevated structure may include alternative access devices. For example, some of the windows on the upper floors of a building may be equipped with devices to allow occupants of those floors to exit and/or enter the building via the window. The devices may be integrated with the building. The alternative access devices also may be used for other applications. For example, the devices may provide access to a structure that is a considerable distance from the ground, such as a tree house or other play structure. The invented access device includes a chute mounted at the top to a pivotal frame mounted, for example near a window or other elevated opening, the chute having a connected or independently deployable step ladder therein and optionally spaced apart support members such as circular, rectangular or oval hoops therearound. The rungs of the step ladder provide a standoff for the webbed material of the chute. Stowage can be in a stowage receptacle mounted to an exterior portion of an elevated structure and deployment can be semi-automatic, reliable and smooth. In accordance with one embodiment of the invention, the access/escape device is hidden within and behind a box-like receptacle on an exterior wall of the building below a window sill. The receptacle generally includes aesthetic elements which closely correspond to aesthetic elements of the structure, rending the receptacle visually unobtrusive and relatively hidden upon casual observation.

Read disturbs in phase change memories may be reduced by progressively reducing the read pulse falling edges. This may reduce the possibility of quenching and inadvertent amorphization of at least a portion of the bit. As a result, in some embodiments, read disturbs may be reduced.

A cable exit trough defining an insert aperture for receiving a modular cable management inserts. The modular insert providing an additional cable management device such as a curved guidewall. The cable management device may alternatively be fixed to the cable exit trough. Removable snap-mounted flanges may also be included in the exit trough. The exit trough may also include an exit cover having a cover plate and a pivot plate hingedly mounted thereto for easy access to the trough.

An information handling system includes a buck converter, having a synchronous switch, to supply power to an electrical load. A first inductor is placed in series with the synchronous switch, and a second inductor is inductively coupled to the first inductor. A switched path recovers energy stored in the first inductor, via the second inductor, when the synchronous switch is open.

The present invention is directed to a system, a module, and an apparatus and method for forming a microelectronic memory device. In one embodiment, a system includes a processor and a controller coupled to the processor with at least one memory module coupled to the controller, the module including a pair of memory devices oppositely positioned on respective surfaces of a substrate and interconnected by members extending through the substrate that couple terminals of the devices, the terminals being selected to include a group of terminals that are configured to communicate functionally compatible signals.

A memory device is operable in either a high mode or a low speed mode. In either mode 32 bits of data from each of two memory arrays are prefetched into respective sets of 32 flip-flops. In the high-speed mode, the prefetched data bits are transferred in parallel to 4 parallel-to-serial converters, which transform the parallel data bits to a burst of 8 serial data bits and apply the burst to a respective one of 4 data bus terminals. In the low speed mode, two sets of prefetched data bits are transferred in parallel to 8 parallel-to-serial converters, which transform the parallel data bits to a burst of 8 serial data bits and apply the burst to a respective one of 8 data bus terminals.
摘要:
A memory system couples command, address or write data signals from a memory controller to a memory device and read data signals from the memory device to the memory controller. A respective strobe generator circuit in each of the memory controller and the memory device each generates an in-phase strobe signal and a quadrature strobe signal. Command, address or write data signals stored in respective output latches in the memory controller are clocked by the in-phase signals from the internal strobe generator circuit. These command, address or write data signals are latched into input latches in the memory device by the quadrature strobe signal coupled from the memory controller to the memory device. In substantially the same manner, read data signals are coupled from the memory device to the memory controller using the in-phase and quadrature strobe signals generated by the internal strobe generator circuit.
摘要:
A partitionable computer system and method of operating the same is disclosed. The partitionable computer system has a state machine, a processor, and a device controller. The state machine can be configured to monitor the status of a partition of the partitionable computer system. The information provided by the state machine can be used to provide security within the partitionable computing system.
摘要:
A method of managing access to a healthcare information system of a healthcare establishment communications network. The method comprises receiving data regarding a wirelessly detectable tag associated with a clinician; determining whether the clinician is positioned relative to a terminal of the healthcare establishment communications network such that a proximity condition is satisfied based at least in part on the data regarding the wirelessly detectable tag; responsive to the proximity condition being satisfied, providing an opportunity for authentication of the clinician; and responsive to successful authentication of the clinician, establishing a session for the clinician between the terminal and the healthcare information system. The ability to detect proximity of clinician facilitates the process by which the clinician may access the healthcare information system, while the requirement for authentication of the clinician minimizes the risk of data being made available to an unauthorized party.
