Abstract: An acceleration switch array having at least two acceleration switches. Each acceleration switch includes a substrate, an anchor attached to the substrate, an electrically conductive mass disposed around the anchor and secured to the anchor by a spring assembly which permits movement of the mass relative to the anchor, and a plurality of electrical contacts positioned at circumferentially spaced positions around and outwardly from the mass. These electrical contacts are aligned along at least one orthogonal axis. A resistor array is electrically connected between the electric contacts of each acceleration switch for each orthogonal axis so that, upon contact between the mass and any of the electrical contacts, an electrical resistance is presented at an output terminal that is unique for each electrical contact for each acceleration switch.

Abstract: The invention is the method and timing sequence for a Reader and\or Writing of RFID Tags (Radio Frequency Identification device), utilizing the various functional components of a single System on a Chip (SoC) as a hardware platform. Extended functions are possible from this baseline function that can cover the full function of an RFID Reader/Writer. The baseline function of this invention is “reading” (interrogating) and “writing” (loading) the EPC code from a passive RFID or active RFID tag by utilization of existing SoC hardware functions (microprocessor, memory and direct multi-port memory controller, and radio transmitter) and small amount of external circuitry (backscatter detector) along with in depth knowledge of the RFID protocol and timing to implement communications protocol. The end benefit is a much simpler hardware platform, much less cost and much less physical space for an RFID Reader/Writer.

Abstract: A learning aid and tutor for school subjects. Comprised of a main-unit which accepts a media for recorded information for a learning activity. The learning activity is both entering the subject matter into the information media, note taking, and using that information media to support a multiple-choice mock-test. The media is customized by and for the user, to subject currently of interest to the user. This media has an answer-to-question correlation function which allows random presentation of information for repeated use. The main-unit has a means for selecting the question in reference to this media and a means for the user to select the corresponding answer in reference to this media. The main-unit has a means for indicating to the user the correctness and incorrectness of their answer selections.
