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： 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.

摘要： A light clock measures time by having a light pulse source initiating a light pulse which travels a preset distance in an open or closed loop. A counter is increased incrementally upon detection of the light pulse by a light pulse detector. Each increment is a time interval, which is determined by the preset distance divided by the speed of the light pulse. If the loop is an open loop, another light pulse may be initiated upon detection of the previous light pulse. If the loop is a closed loop, no further light pulse initiation beyond the initial light pulse is required, but, when necessary, a light pulse amplifier is used to amplify the light pulse for the next cycle around the closed loop in the light pulse transmission device.
摘要翻译：光时钟通过使光脉冲源启动在开环或闭环中行进预设距离的光脉冲来测量时间。通过光脉冲检测器检测到光脉冲时，计数器逐渐增加。每个增量是由预设距离除以光脉冲速度确定的时间间隔。如果回路是开环，则可以在检测到先前的光脉冲之后启动另一个光脉冲。如果回路是闭环，则不需要超出初始光脉冲的进一步的光脉冲启动，但是当需要时，使用光脉冲放大器来放大光脉冲传输中闭环周围的下一个周期的光脉冲设备。

摘要： An electronic timing generator with the output defined by a particular relationship with the phase angle of a periodic input signal. Each period of the input signal is divided into a plurality of ''time slices'' uniquely identified by a numerical value. Each time slice number is applied as a context or address to a storage circuit (34) and the corresponding data retrieved from the storage circuit (34) is used to produce the corresponding output signals through a latching circuit (46). Each context may have associated with it one retrieval step or several retrieval steps. The storage circuit (34) permits the entry of an image input from a second input source (24) that may be a sophisticated programmable computer or simply a plurality of manually operable switches. Or the second source may be merely an image permanently stored in the memory.
