A digital timing system for sports competitions in which a large number of participants progress independently and simultaneously on the same track between a starting line and a finish line. This system comprises a starting time memory, a finish time memory, and a register which permits the temporary storing of the times of a predetermined number of events happening nearly simultaneously. The time is furnished by means of an oscillator and decade counters of which the multiplexed output is applied to the register where the information is entered. This information is shortly thereafter transferred to the starting time memory or to the finish time memory, as the case may be. A subtractor unit subtracts the recorded starting time of a selected participant from the real time when it is desired to display the lapsing time of the participant. At the final, the final track time is displayed. A console with local display allows the operator to obtain all the registered information for every participant, and means is provided for emptying the register by transferring the starting times and the final times to their respective memories. Data processing means is provided for applying handicap or other averaging curves to the results, and suitable print-out means produce written records of the results right at the end of the competition.
The electronic chronometry device (D) comprises an acquisition cell (2) arranged to receive time data (6) coming from at least one time events measurement sensor (8), a storing unit (9) for storing said time data (6), and a processing unit (4) of said time data (6) and associated with said acquisition cell (2). This device is characterized in that said storing unit (9) is associated with an interface (1) which is arranged so as to allow said processing unit (4) to access said storing unit (9) and to read certain of said time data (6) stored in said storing unit (9) without allowing modification of said storing unit (9) by said processing unit (4).
An electronic wristwatch with a printer has a printing head which is arranged inside a wristwatch case with a recording paper loading portion and which performs printing on the recording paper. The printing head is moved by an operation member, and a displacement thereof is detected by a detecting portion. A print control circuit controls printing of the printing head in accordance with a speed corresponding to the displacement detected by the detecting portion.
An electronic device capable of counting down to an integral time point has an integral time point selector for setting an integral time point. A timer serves for recording the current time. A synchronous calculating unit serves for reading the integral time point from the integral time point selector and reading the current time from the timer. The time interval from the current time to the integral time point is calculated as a counting down time period. A counter serves for reading the counting down time interval from the synchronous calculating unit and starting to count down.
An evaluation unit accurately measures the elapsed time between two events. The two events mark the start and stop points of a switching device, such as a motor-operated valve, as it is switching between a first state and a second state. This elapsed time, when compared to a base-line elapsed time or a previously measured elapsed time, provides an indication as to whether the performance of the device has degraded to the point where maintenance or replacement of the switching devices required. The unit includes electro-optical means for individually sensing the occurrence of each event, logic means for selecting the occurrence of either event as the starting or stopping point for the time measurement, and a timing circuit for performing and displaying the time measurement. In one embodiment, the unit includes a microprocessor that processes and stores the time measurements for subsequent retrievel by an external central processor, which processor is programmed to analyze the timing data and generate reports that specify performance criteria associated with the switching device under evaluation.
An athletic training device includes a main control unit coupled to one or more finish line units via a communication link. The main control unit arranged to provide a pre-race start signal and a race start signal simulating an actual race event starting condition. The main control unit further arranged to time the race events, to determine reaction times and to measure weather and/or atmospheric conditions and to store all these as training statistics.
