摘要:
A timer for measuring a time lapsed during an acceleration is disclosed. The timer may include a piezoelectric sensor, an energy storage device and a measurement module. The piezoelectric sensor includes a piezoelectric material for generating an electric potential in response to the acceleration. The energy storage device is electrically coupled to the piezoelectric sensor and is configured for receiving the electric potential generated by the piezoelectric sensor. The measurement module is electrically coupled to the energy storage device. The measurement module measures the electric potential received at the energy storage device and determines the time lapsed during the acceleration based on the electric potential received at the energy storage device.

The present disclosure relates to a measuring device for measuring a fill level of a material in a container based on time of flight principles, including components that serve to generate, transmit and receive a measurement signal and further serve to convert said measurement signal into an analog intermediate frequency signal having an expected signal frequency within a predetermined frequency range, said intermediate frequency signal including information corresponding to the fill level of the material in the container, wherein an analog to digital converter is provided that serves to subsequently sample the intermediate frequency signal, said analog to digital converter employing a sampling frequency less than the expected signal frequency of intermediate frequency signal.
摘要:
Methodologies and constructions of displaying elapsed time on a wristworn device, which include among other things, having at least two display hands one of which that will rotate faster or stop so that they become coincident with each other, then rotate together and then reassume their normal and accurate positions. Such is particularly important with respect to one of the hands that is preferably a seconds hand that might otherwise be displaying seconds of the time of day (“TOD”).

摘要:
To provide a small-sized and thin analog electronic timepiece having a mechanism capable of firmly setting a train wheel for rotating a small second hand. An analog electronic timepiece includes a main plate, bridge members time information indicating wheels rotated with a main plate center as rotation center, a small second wheel rotated with a position other than a center of a movement as rotation center, a hand setting stem, a switching apparatus and a dial. The analog electronic timepiece includes a reset lever constituted to be able to rotate by operating the switching apparatus when the hand setting stem is pulled out to a first stage and a train wheel setting lever constituted to linearly move based on rotation of the reset lever. In a state of pulling out the hand setting stem to the first stage, a train wheel setting lever can set rotation of the small second wheel or other wheel provided to rotate the small second wheel.
摘要:
A time measurement device includes a first motor (1300) for indicating standard time, a second motor (1400) for indicating a chronograph, a generator (1600) which generates driving power for driving the first and second motors by converting mechanical energy into electrical energy, and a zero reset mechanism (1200) for mechanically resetting the chronograph to zero. A compact time measurement device, operable from a low power, is thus provided.
摘要:
A hand display device having a hand driven by a pulse motor in which graduations or symbols representing plural types of functions to be indicated by the hand are arranged so as to display the mutal positions on a dial, and by selecting one of the functions, the hand stays at a position of graduation or symbol corresponding to a selected function for a relatively longer time than that corresponding to unselected function to display functional display selectively.
