摘要： A digital time interpolation system and method for quantizing the time-difference between two digital signals. The present invention measures the time-difference between consecutive zero crossings of a user signal and a reference oscillator (316). The present invention outputs interpolator data, which represents this time-difference in digital form. The present invention includes a quadrature hybrid (305), a synchronizer (304), track-and-holds (T&Hs) (306), analog-to-digital converters (ADC) (308), an encoding circuit (312), and a boundary detector (310). The present invention also includes a system for deskewing the recorded coarse time count and the fine time value. According to the present invention, the reference oscillator (316) is a continuous, two-phase signal having a unique pair of output values at any given instant of its period. By using this reference oscillator (316), the present invention accelerates conversion. The present invention uses a novel boundary detection scheme. By using this boundary detection scheme, the present invention avoids the timing errors which are traditionally introduced by measuring synchronizer outputs directly.

摘要： An improved system for providing ensemble time from an ensemble of oscillators is provided. In the system, a more complete ensemble definition permits a more accurate ensemble time to be calculated. The system takes into account at least weighted time and weighted frequency aspects or weighted time and weighted frequency aging aspects of each oscillator in the ensemble. Preferably, the system takes into account all of the weighted time aspects, weighted frequency aspect, and weighted frequency aging aspects for each oscillator in the ensemble. The weights with respect to each clock can be chosen to be either zero or any positive value such that the sum of the weights for each aspect sum to one. The system can be implemented using a Kalman approach.

摘要： An equivalent time pseudorandom sampling system samples a repetitive waveform within each of several narrow acquisition windows bounding repetitive sections of the waveform in order to obtain equivalent time sample data characterizing the shape of the waveform included within the acquisition windows. The period between successive triggering events is measured and sampling is delayed following an initiating triggering event by delay time adjusted according to the measured period so as to maximize the probability that sampling will occur within an acquisition window. The time difference between samples and subsequent triggering event is measured with high accuracy and resolution utilizing a time interval measurement system based on a dual vernier interpolation.

摘要： A method and apparatus for measuring an elapsed time from a starting signal to an ending signal in a time-to-digital converter. Primarily, the invention calculates an amount of complete cycles from the starting signal to a starting edge of a next clock cycle or the next Nth clock cycle (N is a natural number great than one) after the clock cycle corresponding to the ending signal. The amount is multiplied by a cycle time of the coarse clock to obtain a coarse time value. A time residue is calculated from the ending signal to the starting edge. Finally, the time residue is subtracted from the coarse time value to obtain a required time.

摘要： Portable device for time measurement that counts with the basic functions of time and date, alarm, Timer, Stopwatch, Fixed Interval Timer function, as well as a Variable Interval Timer function. This Variable Interval Timer function allows the user to program multiple different workout or rest intervals, each with a different established time, and without limitation to an amount of fixed and unalterable workout and rest rounds. The user is able to program intervals in order to increase or decrease the workout or rest time. In the same way the user may decide to create intervals of different exercises, some of them for a short time and some of them for a longer time, as well as the rest time. Finally, the user may program the watch to alert them that a change of interval is coming using several different alarms for the different intervals.

摘要： A method and apparatus for real time clock brownout detection. A low power real time clock (RTC) operates continuously to keep time in a global positioning system (GPS) receiver while some receiver components are powered down. In various embodiments, a brownout detector circuit detects a loss of RTC clock cycles. If a loss of RTC clock cycles exceeds a predetermined threshold such that the RTC is not reliable for GPS navigation, an RTC status signal so indicates.

摘要： A real time clock that operates an oscillator within a predetermined range by employing a constant current source. The remaining real time clock logic can be operated at a voltage that is relative to the constant current. Power consumption of the oscillator can be controlled by limiting the current from the constant current source. The outputs of the oscillator can be input into a signal detector. A clocking signal can be produced by the signal detector based on the oscillator signals. The current provided by the first current source is limited to provide low power operation of the oscillator. Optionally, the signal detector can employ a differential amplifier. The differential amplifier receives the oscillator outputs, and provides a clocking signal based on the oscillator outputs.

摘要： Power is conserved in a Global Positioning System (GPS) receiver by shutting down selected components during periods when the GPS receiver is not actively calculating the GPS receiver location. A low power time keeping circuit accurately preserves GPS time when the selected components are deactivated. When the selected components are turned on in response to a wake-up command, time provided from the low power time keeping circuit, corrected for actual operating temperatures, and data from the GPS clock temperature/frequency table, are used to recalibrate time from a GPS oscillator. Positions of the GPS satellites are then estimated such that the real GPS time is quickly determined from the received satellite signals. Once real GPS time is determined from the detected satellite signals, the selected components are deactivated. The process described above is repeated such that accurate GPS time is maintained by the low power time keeping circuit.
