  • Patent number: 8103475
    Abstract: An apparatus for testing connections in a system has a plurality of inputs each adapted to couple to a test point in the system under test and a switching module. The switching module includes a first output selectively coupled to receive a first group of one or more of the inputs and a set of outputs corresponding in number to the plurality of inputs, each being selectively coupled to receive a corresponding one of the plurality of inputs. The apparatus may also include a meter coupled to the first switching module output and an array of nodes coupled to the set of switching module outputs, where each node couples a signal to a row sense line and a column sense line.

  • Patent number: 6351674
    Abstract: A non-invasive method of treating, controlling or preventing medical, psychiatric or neurological disorders is provided using transcutaneous electrical stimulation. A plurality of stimulation frequency parameters are used ranging from a relatively high frequency, for example about 40,000 Hertz, to a relatively low frequency, for example about 250 Hertz. The entirety of frequency parameters may be administered at each of a plurality of stimulation intensity levels. In particular, stimulating may begin at a first highest frequency parameter and a first lowest intensity parameter with the stimulation frequency parameter incrementally decreasing to the lowest frequency parameter. Then the frequency parameter is returned to the highest frequency parameter, and the intensity parameter increased to a next higher intensity parameter, and again stimulating through the plurality of frequency parameters from the highest frequency to the lowest frequency.

  • Patent number: 5097305
    Abstract: An integrating photosensor includes an NPN phototransistor having its collector connected to a source of positive voltage, a P-channel MOS transistor having its gate connected to row-select line, its source connected to the emitter of the phototransistor, and its drain connected to a column sense line. The NPN phototransistor has an intrinsic base-collector capacitance. An integrating sense amplifier according to the present invention includes an amplifying element having an inverting input and a non-inverting input. The non-inverting input is connected to a source of reference voltage the inverting input is connected to a sense line. A P-channel balance transistor is connected between the inverting input and the output of the amplifying element and a capacitor is also connected between the inverting input and output of the amplifying element. An exponential feedback element is connected between the output and the inverting input of the amplifying element.
