Abstract: In an example embodiment, a computing module includes a case, an optical display subsystem coupled to the case, a circuit element assembly, a power cell and an interface connector. The case includes a bottom portion and multiple lateral sidewalls. The case defines an enclosure. The circuit element assembly is positioned within the enclosure and is coupled to the optical display subsystem. The power cell is coupled to the circuit element assembly. The interface connector is defined in the case and includes multiple side openings, multiple bottom openings and multiple connector pads. The side openings are defined in at least one of the lateral sidewalls. The bottom openings are defined in the bottom portion of the case. The connector pads include multiple side pads coupled to the case and in communication with the side openings and multiple bottom pads coupled to the case and in communication with the bottom openings.

Abstract: A one-piece housing holds an image sensing module having a transparent image sensing surface and a document drive roller in close alignment. A cover closely fits around the housing and is positioned in close alignment with respect to the housing. The cover and housing cooperate to define a document entry path in which a plurality of sensors are located: a set of document-skew-detecting sensors and a set of document-insertion-detecting sensors, the sets of sensors acting independently of each other. The number and spacing of the sensors is the set of document-insertion-detecting sensors is such that the narrowest expected document encounters at least one such sensor. The cover and housing also cooperated to define a document scanning path and one or more document exit paths.

Abstract: A coin counting device for simultaneously counting a number of coins, all of which are of a selected denomination. The device includes a hopper, an inclined planar member to receive coins from the hopper, members mounted to prevent coins from rolling down the planar member and to prevent coins from sliding down the planar member atop one another. The device also includes an array of pin members to disperse the coins transversely across the surface of the planar member. Gate means are mounted at the bottom edge of the inclined planar member to count coins as they slide passed.
