摘要: A universal timer system with selectable time base and clock output is operable in several modes, including a plurality of timers interconnected in a sequentially mutually exclusive operation mode. In this mode, a succession of n number of events is counted using n number of timer units. The initial event is counted and timed on unit no. 1, the second on unit no. 2, etc., each unit operating to the mutual exclusion of all others. A group of three displays for each unit provides unique statistical information about each event which is useful to the time study engineer or statistician in computing values such as the number of observations necessary for a specific level of confidence, so that a real time determination of the required duration of study may be made.

摘要: A system for indicating the sweep rate of an oscilloscope time base. A counter is enabled by a sweep gate signal to permit clock pulses having a predetermined repetition rate to be counted during the time a sweep-driving ramp waveform is generated. The count output, which is proportional to the length of a time-base sweep, is decoded to generate specific control signals indicative of the sweep rate thereof. The control signals may then be used by a utilization means to provide a visual readout of the time-base sweep rate or to provide auto ranging for a digital voltmeter scaled in time units for time interval measurements.

摘要: A fully electronic chronometer using a quartz crystal as a frequency standard and displaying mean time by the use of electronically operated digital read-outs. The circuit permits the display of the instant of time at which a switch is operated, while mean time continues to be counted by the circuitry. Other features include conservation of power by display of mean time only upon demand and the provision for control and display remote from the timing circuitry.

摘要: Apparatus is described for effecting an objective measurement of the intensity of pain induced by a nociceptive irritation of one of the paws of a laboratory animal. The degree of pain is manifested by the animal's repetitively lifting the injured (i.e., test) paw. The test paw is normally in contact with a pair of adjacent conductors of a planar conductor array forming the floor of the animal's cage. Such paw is provided with an electroconductive coating on its plantar surface, so that when such paw is irritated each resultant lifting of the paw from the surface breaks the contact between the bus bars. The total time over which the conductively adapted test paw completes the circuit between the bus bars during a prescribed measurement interval is recorded, together with the total number of disconnections of the paw-base contact over such interval.

摘要: A portable self-contained testing apparatus is provided for accurately determining the stopping time of a press after the initiating of a STOP signal. The apparatus includes a detector head, a stationary grid, a synchronizing touch switch, and a control box with a digital readout. The detector head is mounted on the press ram to be movable therewith while the stationary grid member is mounted proximate to the detector to allow the detector to scan the grid lines on the grid as the ram moves. The touch switch is used to initiate the press STOP control signal and provides a signal to the control box to initiate grid count by the detector head whenever the press STOP signal is initiated through the touch switch. The control box has circuitry to convert the grid count signals from the detector head and the press STOP signals from the touch switch to a digital readout of the time required for the press to actually stop after the initiation of the press STOP signal.

摘要: A time of event recorder in which a Gray Code counter is regularly advanced at a predetermined frequency by a crystal controlled oscillator and the outputs from the counter stages are applied to the digit lines of a MATED FILM memory array, such that when an event associated with a given word line of the memory occurs, the counter contents at the time of occurrence of the event are stored in that memory word register. A second array of MATED FILM elements is also provided which has its digit lines energized at a fixed submultiple of the frequency of the crystal controlled oscillator to provide greater accuracy and resolution than is obtainable from the Gray Code counter. The elapsed time between two events may be obtained by reading out two words from the memory and determining the difference in counts associated with the two events under consideration.

摘要: A digital time indication system for displaying the time to the next racing signal of a yacht race. A quartz crystal oscillator provides time reference signals to a frequency divider chain. The divider chain counts down and provides digital signals representing the number of minutes, tens of seconds and seconds to the next starting signal. The divider chain automatically recycles so as to countdown for the next period of preselected length. Switching means are provided to select the desired period from one of several standard yacht racing signal time intervals. Counter preset means are provided to synchronize the counter to a racing signal. Counter decoding is provided to gate an audio frequency signal to an audio amplifier and electromagnetic sound transducer so as to provide an audible beep at a pre-determined rate during the last several seconds preceding the next racing signal. The digital signals from the divider chain are conditioned by signal drivers to control a digital numerical display. The display provides an indication of the time remaining until the next racing signal. Additionally the timing signal derived from the crystal oscillator is also applied to an upcounting chain to provide signals representing the normal time-of-day. Means are provided to select whether the digital display indicates the time-of-day or the time to the next racing signal. Additionally, means are provided to set the time-of-day indication to correspond with a local time standard.

摘要: A chronographic electronic timepiece adapted to display elapsed time wherein the time displayed is rounded off to the nearest half period is provided. Chronographic divider stages adapted to apply signals representative of elapsed time to associated display elements include a binary divider stage adapted to produce elapsed time signal having a period which is the longest time period not displayed by said display elements. A rounding off circuit is provided for advancing the period counted by the binary divider stage in order to advance the count thereof by half a period to effect a rounding off of the time displayed by the display elements.
