  • Patent number: 8120578
    Abstract: A controller for controlling a cursor includes an identifying module for identifying at least one of a first period when a cursor is in motion and a second period when the cursor is not in motion, and a calibrating module for calibrating an input parameter signal using a first hands-off test during the first period and a second hands-off test, different than the first hands-off test, during the second period.

  • Patent number: 6957337
    Abstract: A method and apparatus for authenticating (or identifying) a subject, includes using one or a plurality of biometric measurements for authentication (or identification) without any sharing of the subject's biometric data with a party requesting authentication.

  • Patent number: 5945979
    Abstract: A cursor control apparatus allows switching between at least two modes of cursor position control operation; one of which provides emulation of cursor control keys with a graphic input device. The emulation of cursor keys provides control of cursor location in a digital mode in which the cursor is rendered only at locations corresponding to character areas, fields or cells as opposed to an analog mode in which the cursor may be positioned at higher resolution, either by providing multiple increment inputs to a cursor position controller or by direct application of signals to cursor key inputs of a processor. Enhancements of the digital mode of operation including cursor movement speed control are also provided.

  • Patent number: 5870078
    Abstract: A low-cost circuit processes, with high precision, the output signals of a pointing stick used for controlling a cursor on a computer display screen. A two-stage method of high precision moderate range analog-to-digital (A/D) conversion is combined with a known method of A/D conversion by sweeping a reference voltage across the range of the voltage to be measured at a known rate and noting the time of coincidence. Operational amplifiers of moderate quality are used in an open-loop mode, so that the operational amplifier inputs are high impedance. In order to get sufficient isolation from power supply noise and variations, the analog circuitry is isolated from the supply voltage while measurements are being made.

  • Patent number: 5831593
    Abstract: A battery powered sensing device using an analog sensor has electronic circuitry that maintains sensitivity and calibration of the sensing device during quiescent periods with very little power drain. In one implementation, a joystick is provided with a sensitive analog sensor, such as strain gauges, connected to the shaft of the joystick. The strain gauges are connected in a bridge circuit across which a voltage is applied. Three operational amplifiers are connected to combinations of the strain gauges in the bridge circuit to generate X, Y and Z output voltages corresponding to the combined signals generated by the strain gauges. A microprocessor receives outputs from the sensitive analog sensor and generates a sample signal and performs a recalibration of sampled signals during periods of inactivity.

  • Patent number: 5696535
    Abstract: A threshold discrimination filter circuit compares an amplitude and rate of change of amplitude of an output of a graphic input device such as an isometric joystick including strain gauges and a fixed resistance in a hierarchical voltage divider with threshold reference signals and corrects the output of the graphic input device based on previously stored samples thereof when a selection or deselection action by a user is discriminated. Outputs of the graphic input device are supplied directly to a CPU of a data processing device between masking periods so that graphic manipulations such as dragging can be performed while masking unintended change of specified display location during selection and deselection.
