Abstract: The present invention is directed to a network attached data storage system. In one embodiment of the invention, the system provides high data density by providing the capability to mount four data storage devices, such as disk drives, in a row that extends across the width of an enclosure that conforms to the 1U specification. In a further embodiment, the system includes a latch that allows a data storage device that is disposed on a carriage to be attached and detached from a receiving bay within a disclosure. The latch includes a sensor that provides an electrical signal which is indicative of when a user is disengaging the latch to remove the data storage device from the enclosure. This signal can be used to prevent any data that is being transferred to or from the data storage device from being lost and/or corrupted during removal of the data storage device.

Abstract: A laptop computer display module for use in a clamshell type laptop computer includes a telescoping rail assembly that enables the display module to be extended upwardly from a keyboard module of the laptop computer when the display module is rotated to an open position. A computer display panel is rotatably mounted to a display support member of the display module adjacent a top margin of the display panel so that the display panel can be manually swung away from the display support member and toward a user of the laptop computer. The invention enables the display panel to be positioned at a comfortable viewing angle without blocking access to the keyboard module for typing and is particularly useful in depth-constrained workspaces such as airline passenger seats, where the display support member must be positioned at an acute angle relative to the keyboard module.

Abstract: An interface layer and method is provided that permits applications, without modification, to operate with any type of meter. The interface comprises an abstraction layer and library or repository of descriptions specific to each meter type. The abstraction layer provides the capability to communicate with any meter through a variety of applications. Upon receiving an application request, the abstraction layer retrieves the description for the particular meter type from the repository and processes the request. In this manner, only one data representation is needed for applications to communicate with a wide variety of meters.

Abstract: In an assembling structure of a vehicle center cluster, plural electrical devices are detachably assembled to a holding member to be removed from an inside of a passenger compartment while the holding member is fixed to a dashboard. Therefore, for example, when a CD deck is removed from the center cluster into the passenger compartment among the electrical devices, only the CD deck can be removed from the holding member into the passenger compartment without removing the other electrical devices, in a fixed state of the holding member to the dashboard. Accordingly, removing operation of the electrical devices can be made simple.

Abstract: An automatically operating interlock prevents connection of an electrical device within a cabinet unless the cabinet door is closed. The interlock is particularly useful for circuit breakers contained within arc-resistant cabinets. The interlock includes a spring-biased locking plate reciprocating between a locked position wherein the locking plate resists movement of the levering-in locking plate, and an unlocked position wherein the locking plate permits movement of the levering-in locking plate. The locking plate is spring-biased towards its locked position, and is pushed from its locked position to its unlocked position when the cabinet door is closed. Access to the hex drive of the levering-in rod is thereby resisted when the cabinet door is open.
