An output of an oscillation circuit is inputted to a frequency dividing circuit, and through the signals divided by the frequency dividing signal circuit 104, an interrupt signal circuit 104 starts to operate to generate an interrupt signal to a CPU. The CPU reads the data programmed in a ROM and performs various arithmetic operations. A flag management circuit outputs a determination flag for collectively determining either a plurality of conditional branch operations or a portion of the branch...

A time-error-compensating apparatus and method corrects errors in a real-time clock caused by temperature fluctuations or other external influences. The apparatus includes a frequency counting unit which counts a high-frequency clock signal and a low-frequency clock signal, and a time compensating unit which computes a clock count compensation value based on a comparison of the count values of of the low-frequency and high-frequency clock signals. Correcting time using a high-frequency clock is ...

A time correction system has a timepiece with pointers for displaying the time, and a correction instruction device. The correction instruction device has a timing section for timing reference time data, a time input section for inputting pointed time data corresponding to the time indicated by the pointers, a comparison section for comparing the reference time data and the pointed time data, and a communication section for outputting a correction instruction signal based on the results of this ...

A simple electronic horological device, termed a time cell, is presented with associated methods, systems, and computer program products. A time cell has an insulated, charge storage element that receives an electrostatic charge through its insulating medium, i.e. it is programmed. Over time, the charge storage element then loses the electrostatic charge through its insulating medium. Given the reduction of the electric potential of the programmed charge storage element at a substantially known ...

The timing system for GPS has a week counter that recycles at intervals of about 20 years. The first recycling will occur on Aug. 22, 1999, producing a time ambiguity in GPS signals. The invention employs a count of leap seconds to resolve the ambiguity and extends the useability of GPS in its present format by more than a century.

A low power consumption timing device using an oscillator and chained CMOS flip-flop devices providing all time-dependent functions, with an audible and/or visual alarm which signals after a predetermined elapsed time and continues until deliberately reset especially useful for repetitively timed events such as reminders for taking medication at fixed intervals. When reset the elapsed timer begins the next timed interval. A minor circuit revision, makes possible an automatic reset of the timer m...
