摘要： An electronic horologic instrument, such as an electronic watch or clock, utilizes randomly-generated energy to produce electrical pulses in synchronism with the generated energy. The electrical pulses are counted until a predetermined count is reached. When this occurs, the timekeeping circuitry is stepped by a unit of time such as one second or some other convenient fraction thereof. The electrical pulses produced, although random over a short time period, have an average rate over a long time period that follows well-established statistics, to provide a horologic instrument with an acceptable degree of accuracy.

摘要： Disclosed is a solid state wristwatch incorporating a nuclear timing source. A radioisotope such as Radium 226 decays, producing alpha particles that are detected and converted into electrical pulses of constant frequency. The electrical signals are divided in a CMOS binary chain and used to drive a digital time display of light emitting diodes. The watch is powered by a conventional 3 volt battery.

摘要： A timepiece wherein the frequency standard takes the form of a radioactive source having a prolonged half-life, the alpha particulate emanations from the source being converted into electrical pulses, the pulses then being scaled down to produce low-frequency control pulses at a constant rate, which operate a time indicator.

摘要： A radioactive timekeeping standard constituted by a radioactive source of alpha particles combined with a solid-state radiation detector, the source being in the form of a backing having a planar array of discrete islands of a radioactive isotope, the alpha particles emitted therefrom passing through an apertured mask and impinging on the sensitive surface of a solid-state radiation detector, the geometry of the mask apertures, which are in a matching array, being such as to restrict emanations impinging on the detector surface to substantially normal angles of incidence and in addition preventing particles emanating from any one island from impinging on a neighboring portion of the detector surface associated with another island.

摘要： An absolute time scale clock includes a radioactive isotope and a computer. The computer includes a processor that determines an indication of the current absolute time and a memory that stores a decay constant of the radioactive isotope, a reference time, and an amount of the isotope at the reference time. A energy supply that provides power to the computer. The absolute time scale clock further includes a detector positioned to respond to emissions from the radioactive isotope. The detector generates an indication of the number of emissions over a time interval that varies with the decay rate of the isotope. The processor is responsive to the indication from the detector, the decay constant, the reference time, and the reference amount to determine the indication of current absolute time.
