A computer mouse operation pad and forearm support assembly for providing forearm and wrist support to a user operating a computer mouse on a computer mouse operation pad from a sitting position, the assembly compromising (i) an integrated unit formed by joining a computer mouse operation pad to a forearm support in such a manner that a front region is defined by the computer mouse operation pad, a back region is defined by the forearm support, and a middle region is defined by the natural repose of the wrist of the user when the forearm of the user is resting upon the forearm support while the user is operation the computer mouse on the computer mouse operation pad, and (ii) a clamp for attaching the assembly to a worksurface having top, front and bottom surfaces, the integrated unit attached rotatively to the clamp.

Abstract:
Workstations with the look and feel of millwork but with the flexibility of systems furniture comprise modules constructed from a relatively few number of elements. The modules are based on several basic geometries, and comprise a horizontal work surface, a forward support panel assembly, and end panel assemblies. In addition, each module can be equipped with transactional shelves and various accessories, e. g. pull-out writing shelves and pencil drawers, drawer pedestals, courtesy shelves, lighting, etc. The elements of the modules are constructed from durable materials that are easy to maintain and clean. Certain embodiments of these workstations are particularly well adapted for use in health care settings.

Abstract:
A voltage regulating transformer utilizing a microprocessor and a versatile multipurpose set of hardware modules and software modules it is described. A standard tap changing mechanism is driven in response to an analog control signal to change the output voltage of the transformer in response to digitally sampled values of voltage and current which have been transformed from the time domain to the frequency domain through a software program using Fourier transform techniques. The output current is also transformed and digitally processed to determine the power factor and the direction of power flow through the transformer. By inserting the digital values of the line characteristics to the load, line drop compensation is provided for. The difference in voltage across the input and output transformers is transformed to a digital signal and internally processed to provide an indication of the position of the tap changing mechanism without relying upon mechanical devices. The various software and hardware modules are designed so as to be readily utilizable in other electrical distribution controls.
