Abstract: A commercial-transaction weighing instrument (110) subject to W&M legal controls, configured with a weighing platform (12), at least one load cell (16), a controller (120) with weight-processing (122) and communications (124) modules, and software to be implemented on a general-purpose computer with display and data entry capabilities. The general-purpose computer itself is not subject to legal controls. The weight-processing module receives data from the at least one load cell and generates output data in the nature of weight and legally-required weighment information. The communications module receives the output data of the weight-processing module and further transmits the data to a general-purpose computer (136). Software implemented on the general-purpose computer has program code for establishing encrypted bidirectional communication with the communications module and to operate as the primary display device for the weighing instrument.

Abstract: A shredding assembly for a grinder pump includes a stationary shredding ring mounted to an inlet of the pump, and a cutting device rotatable about an axial direction and fixed to a shaft of the pump. The shredding ring includes a top face, a bottom face, and a central opening extending from the top face to the bottom face and delimited in a radial direction by an inner periphery. Slots extending in the axial direction are formed in the inner periphery. The cutting device is positioned in the central opening of the shredding ring, and includes a front face and a back face. The front face includes a plurality of first cutting members extending in the axial direction and facing the slots. The back face includes a second cutting member projecting beyond the central opening with respect to the radial direction.

Abstract: A system and method for assisting a party (e.g., a freight carrier) in determining whether dimensional weight or actual weight should be used for shipping particular freight. A weighing device may be associated with a forklift, and may also include a DIM comparator in association with the forklift. The DIM comparator may have an input and a display of information, and may also include a CPU unit for storing and processing data. The DIM comparator may allow an operator to input various data through selectable menus and tables. The DIM comparator then determines a theoretical dimensional weight of the freight and compares it to the actual weight as measured by the weighing device associated with the forklift. This comparison is then displayed to the operator and a prompt is provided if a dimensional weight should be determined.

Abstract: An improved methof of producing an interference based computer generated hologram (CGH), where the angle dependent and angle independent components of light emanating from point sources of light on a virtual 3D object are calculated separately. This allows the angle independent components to be calculated only once per point source of light, but enables the angle dependent components to be calculated on a each point source of light to each CGH pixel basis. This method reduces the number of calculations required to produce a CGH, thus reducing computational load, but fully retains the image quality of the 3D image.
