Abstract: Disclosed is a device adapted to mount to a desk for use with a computer keyboard, a mouse, or a system such as a laptop computer. In one embodiment, the device includes a stationary bracket attachable to the desk, a main housing in sliding engagement with the stationary bracket, and a keyboard support tray connected to the main housing and adapted to support the keyboard or laptop computer. The device further includes a palm rest and an optional mouse support tray. The elevation of the keyboard support tray, palm rest, and mouse support tray may be independently adjusted. The keyboard and mouse support trays may also be independently tilted to achieve a comfortable working configuration. A locking member may also be provided to secure the housing and keyboard support tray in a stored position under the desk to prevent theft or computer system operation by unauthorized persons. An anti-pry feature may also be provided for additional security.

Abstract: Disclosed is a system for positioning a computer mouse relative to a computer keyboard. The system comprises a keyboard support tray having a front portion, a rear portion, and a support surface which is adapted to support the keyboard. The system further comprises a palm rest connected to the front portion of the keyboard support tray. The system further comprises a pointing device positioning member having a support surface, a first end, and a second end. The first end of the pointing device positioning member is slidably disposed upon the wrist rest while the second end is slidably engaged with the rear portion of the keyboard support tray. In operation, the pointing device positioning member may be selectively moved about the wrist rest and the rear portion of the keyboard support tray to thereby position the computer mouse relative to the keyboard.

Abstract: Disclosed is a system for positioning a pointing device such as a computer mouse relative to a computer keyboard. The system comprises a keyboard support tray having a support surface, first and second side walls, and a rear wall. The support surface is adapted to support the keyboard. The system further comprises a palm rest connected to the keyboard support tray. The system further comprises a bracket member having a mounting portion and a channel. The mounting portion of the bracket is adapted to engage with the rear wall of the keyboard support tray. The system further comprises a pointing device positioning member having a support surface, a first end, and a second end. The first end of the pointing device positioning member is slidably disposed upon the palm rest while the second end is slidably engaged within the channel of the bracket. In operation, an operator may slide the pointing device positioning member to any one of a variety positions above the computer keyboard.

Abstract: Disclosed is a device adapted to mount to a desk and for use with a computer keyboard and/or a mouse. In one embodiment, the device comprises a stationary bracket attached to the desk, a main housing attached to the stationary bracket, a keyboard support tray supportably connected to the main housing and adapted to support the keyboard. The device further comprises a palm rest movably connected to the main housing and a first engagement member being operable in a first position wherein the keyboard support tray and the palm rest are substantially movable and a second position wherein the keyboard support tray and the palm rest are substantially fixed. In a second embodiment of the present invention, the device may further comprise a mouse support tray movably connected to the main housing so that the user of the computer system may adjust the position of the mouse support tray for optimal ergonomic use of the mouse.

Abstract: The present invention is directed to various configuration features of a logic array that includes a plurality of individually configurable logic cells arranged in a matrix. These features include reconfiguration logic for reconfiguring logic cells in a selected portion of the matrix using a window-based protocol. The array also includes configuration data storage means for storing configuration data utilizable for configuring the logic elements, wherein each logic element includes a working data storage register, and reset circuitry for modifying the configuration data without modifying the working data. The array further includes read disable circuitry and write disable circuitry for disabling read access and write access, respectively, to the configuration data. The array further includes a comparison protocol mechanism for checking the configuration data against data on the array pins.

Abstract: The present invention provides a configurable logic array that includes a plurality of individually configurable logic cells arranged in a matrix that includes a plurality of horizontal rows of logic cells and a plurality of vertical columns of logic cells. The array further includes at least one horizontally aligned local bus running between adjacent rows of logic cells, the logic cells in the adjacent rows being connectable thereto, and at least one vertically aligned local bus running between adjacent columns of logic cells, the logic cells in the adjacent columns being connectable thereto. The array further includes a dynamic tristate bus driver associated with each logic cell and connectable to the local busses associated with the corresponding logic cell and means for controlling the dynamic tri-state driver through one or more combinations of inputs to the logic cell.

Abstract: A low transistor count programmable bussing resource for a programmable logic array allows the use of the bussing resources as inputs or outputs to a cell in the array and allows connections between different buses without effecting the normal use of the cell. The bussing resource allows efficient routing of signals between cells and is symmetric to allow rotation of logic macros built using combinations of cells and buses.
