Abstract: A system, method, and program product for determining an approximate position of a global positioning system (GPS) receiver of a global positioning receiver connected to a computer. The computer compares obtained image data of landmarks with a database of known landmarks to determine an approximate position of the GPS receiver at a specified time. The computer converts and transmits an error signal.

Abstract: An apparatus, system, and method are disclosed for controlling an electronic display. An activity module receives a brightness restore signal and sets a brightness level of an electronic display to a default brightness level in response to the brightness restore signal. A brightness decay module dims the brightness level of the electronic display from the default brightness level to an intermediate brightness level at a first dimming rate. The intermediate brightness level is selected from one or more intermediate brightness levels. A plateau module maintains the brightness level of the electronic display at the intermediate brightness level for a predefined period of time. A minimum brightness module dims the brightness level of the electronic display from an intermediate brightness level to a minimum brightness level at a second dimming rate.

Abstract: A system and method are disclosed for detecting and interpreting touch input to a touch-sensitive display screen, while identifying and excluding activity not intended as touch input. A positional sensor is used to obtain positional information of a touch to the display screen using a finger or stylus. Intended touch input is verified by sensing vibration, displacement, or other movement caused by an impulse to the display screen to verify that the activity is intended as touch input. Intended touch input is further verified by timing signals from the positional sensor and the impulse sensor to determine that these two signals likely resulted from intended touch input, and not from separate or unrelated activity not intended as touch input.

Abstract: Two levels of liquid crystal material and upper, center and lower transparent members are sandwiched to form a stacked display. Segment electrodes, which are disposed on opposite sides of the center transparent member, are controllable to selectively display information in one of the two levels while the other level is caused to remain transparent. By applying different waveforms to the levels, one level can be energized while the other is held inactive.

Abstract: A rapid start oscillator latch circuit for avoiding long start up time while maintaining minimum operating power for a crystal oscillator in an electronic watch. The oscillator is operated at a relatively high gain immediately after power is applied and until the oscillator is running, after which the oscillator is caused to operate under the normally preferred conditions. A power up pulse sets a latch and the latch is reset by either a pulse from the prescaler or a manual input. When the latch is set, the oscillator circuit is modified for quick start-up. After the oscillator is running, it activates the prescaler, and after several cycles of clock inputs to the prescaler, an output from the prescaler or a manual input resets the latch and the oscillator is returned to its normal operating condition.
