  • Publication number: 20110177383
    Abstract: A cell module for a modular battery includes a plurality of positive electrode plates having positive connections extending from the positive electrode plates and having a first end and an opposite second end; a plurality of negative electrode plate having negative connections extending from the negative electrode plates and having a third end and an opposite fourth end, the positive and negative electrode plates alternating and being stacked so that the first and third ends are on a same side of the cell module and the second and fourth ends are on an opposite side; and a separator between the positive and negative electrode plates and covering the second end and the third end. A modular battery and a method are also provided.

  • Patent number: 6879805
    Abstract: A test form comprises a substrate, a chromogenic material applied to at least a top surface portion of the substrate, a removable opaque layer overlaying a portion of the chromogenic material, the chromogenic material being adapted to irreversibly generate a visible change in color to form a desired indicia, upon exposure of the area to an activating agent such as heat to predetermined areas on a bottom portion of the substrate, all without disturbing the opaque layer covering the indicia so produced. The present invention is further directed to a method and system for customizing a test form having a removable opaque layer, by permitting printing under the opaque layer to be concealed until the corresponding opaque layer covering the indicia is removed.

  • Patent number: 6210171
    Abstract: An answer form for use in answering multiple-choice questions is configured to provide immediate feedback to an examinee as to whether a correct response has been made for each question, and if not, permits the examinee to proceed to determine the correct response. The multiple-choice test answer form provides for recording fill or partial credit for any response on the answer form, and is capable of being scored either manually or automatically by apparatus for form scoring. The answer form includes a substrate such as a paper surface upon which is printed a varying number of rows and columns of answer alternatives. The rows correspond to the questions to be answered, and the columns correspond to the number of answer alternatives for each question. Each alternative is covered by an opaque coating that can be rubbed off to reveal whether a particular alternative conceals an indication that the alternative is correct or not. A blank space beneath the opaque coating indicates an incorrect alternative.

  • Patent number: 5715432
    Abstract: A method for developing a network analysis and modeling application program includes the step of interactively selecting and displaying a graphical object. An instantiation of the graphical object is representative of at least a portion of a network. The graphical object is further used in an executable network analysis and modeling application program. The preferred embodiment further includes the step of editing the selection of the graphical object.
