Abstract: An electronic timepiece has a minute hand, hour hand, chronograph second hand, chronograph minute hand and chronograph hour hand. A first gear train is provided for transmitting the output of a motor to a second wheel of the chronograph second hand. A second gear train is provided for transmitting the rotation of the chronograph second wheel to a minute wheel of the chronograph minute hand, and a third gear train is separately provided from the first gear train and provided for transmitting the rotation of the chronograph second wheel to an hour wheel of the chronograph hour hand.

Abstract: An electronic watch equipped with an analogue type timer which is capable of shifting the timer from the "minute" stepping mode to the "second" stepping mode in the final part of the length of set time.

Abstract: An electronic analog timepiece provides for elapsed and intermediate split time measurement with hands indicating fractions of a second, seconds and minutes. Hands do not move except by a user stop or split command. Then the hands rapidly move to positions indicating elapsed or split time. Alternatively, conventional continuous indications are provided except when the internal battery nears depletion, or intermittent operation of the hand indicating fractional seconds provides warning that the battery nears depletion. A wristwatch type analog display stopwatch using a plurality of step motors to drive the hands is produced.

Abstract: A dual timing event stopwatch incorporates a primary timer triggered by a remote light emission detected by an optical pick-up sensor, and a secondary timer manually triggered by a user-actuated switch. The user may select between a first operating mode wherein both timers are concurrently stopped in their interval counted cycles by a manually operated switch, and a second operating mode wherein the second timer is terminated by the manual switch and the first timer is terminated by a second remote light emission detected by the optical pick-up sensor.

Abstract: A time keeping and recording device is provided, which is particularly suitable for use by lawyers and other professionals to record in an automated fashion the time spent on various activities, together with other information identifying such activities. The preferred embodiment of the invention comprises a stop clock, audio recording means, timer means, and circuit means including switch means, wherein the switch means is operable to reset and start the stop clock, and is operable to stop the stop clock, and wherein either of such operations causes the timer to enable the recorder to operate for a pre-specified time interval, during which a spoken message may be recorded.

Abstract: A digital display arrangement is provided for balanced general timekeeping having centrally-positioned hour digits and two sets of smaller, equal-sized minute digits flanking the hour digits for trailing and leading readout, with hockey stick-shaped display elements positioned below the minute digits and oriented to give graphic symbols of minutes increasing past the present hour and minutes decreasing toward the next hour, respectively. Means are provided for blanking the hour digits and simultaneously energizing a chronograph time display which, because of resulting large spaces uniquely seen only between the chronograph digits, presents substantial visual contrast from, and minimum potential for ambiguity or confusion with, the general timekeeping mode.

Abstract: A drag race reaction timer including a displacement measuring means comprising a roller contained within a housing and a switch operable upon contact with said roller. Circuitry is provided to activate yellow and green lamps simulating the start of a drag race and to determine the time difference between the appearance of the green lamp and displacement of the auto by a predetermined distance. If the auto moves the predetermined distance before the appearance of the green light, a red light is activated.

Abstract: The clock comprises an electronic part including a quartz oscillator controlling a motor. The motor drives, through a wheelwork, both continually running hands and stoppable hands. By means of a manually operated actuator, the stoppable hands can be operatively connected to, or disconnected from, the motor, or reset to zero. With the motor running, the continually running hands can be set to a desired time by means of a hand setting actuator. The crystal-controlled drive provides for high accuracy and the analog indication of the time and of the clocked intervals make reading convenient and fast.

Abstract: There are provided a frequency divider for dividing the frequency of the frequency signal produced by an oscillator, a counter for counting the number of the frequency divided fundamental signal, an input circuit for prestoring a time to be announced in a memory device so as to operate an alarm device, a comparator for comparing the time counted by the counter with a preset time, an input circuit supplied with a message so as to display the message concurrently with the operation of the alarm device, a character memory device for storing the applied message, and a display device for displaying the stored message. The content of the counter is compared with the time to be announced preset in the memory device. When a coincidence holds a buzzer is operated and at the same time a predetermined message preset in the character memory device is displayed on the display device.

Abstract: A stop watch comprising a second hand and a subsecond hand includes manually actuatable switches for producing start, stop and reset instruction signals. A first stepping motor and a first drive controller for the stepping motor drives the second hand, while a second stepping motor and a second drive controller drives the subsecond hand. The second drive controller includes a counter for counting subsecond clock pulses in response to the start signal for effecting the display of the contents of the counter by the subsecond hand in response to the stop signal.
