Abstract: Swim/sporting event timer/counter. A waterproof housing has upwardly projecting digital displays and two spaced ultrasonic receivers. A swimmer wears an ultrasonic transmitter tuned to ultrasonic receivers. by measuring the time differential for the ultrasonic signals from the transmitter to reach the receivers in the housing, the position of the swimmer (i.e., in front of, directly over, or behind the housing), is determined. Laps are identified by determining when the transmitted signal changes from being received by the two receivers by an increasing time differential to being received by a decreasing time differential. Each time the swimmer passes over the housing, the numbers on the display are inverted so that the swimmer may look down into the water and see the time regardless of which direction the swimmer is traveling in the lane or other predetermined course.

Abstract: An electronic integrator for integrating a linear voltage signal utilizes a voltage-to-frequency converter for converting the voltage to input frequency. A binary counter counts pulses of the input frequency. The binary counter generates a first operating frequency which is applied to a scaling circuit and another calibration frequency which has a much higher rate than the operating frequency. Both, however are proportional to the input frequency. The scaling circuit scales the operating frequency to a selected extent to form a counting signal. Using the double pole switch, either the calibration frequency or the counting frequency are applied to a pulse counter which is either used to integrate the input voltage signal by counting up pulses of the scaled counting signal, or the integrator can be calibrated using the calibration frequency which quickly increments the pulse counter.

Abstract: The invention relates to a process for using a binary register with n bistable cells making it possible to determine the ratio of two frequencies and an apparatus for performing the process. This use process consists of supplying to a counting input of the binary register with n bistable cells a first pulse signal S.sub.1 of frequency F.sub.1 and to a shift input of said register a second pulse signal S.sub.2 of frequency F.sub.2 with F.sub.1 >>F.sub.2, the register content being incremented at each pulse of the first signal S.sub.1 and divided by two at each pulse of the second signal S.sub.2, whereby the register content can also be loaded into a buffer register at each pulse of the second signal S.sub.2. The invention more particularly applies frequency discrimination, the determination of an unknown frequency on the basis of a known frequency and to the control of analog display means of the logarithm to base two of the ratio of two frequencies.

Abstract: Sensors in the infeed and output stackers, under control of the microprocessor, monitor the sheets. The apparatus is started automatically by placing sheets in the infeed. A count of the sheets is developed and displayed as the sheets are fed. When the infeed is empty and the output contains sheets, the count is retained. If sheets are removed from the outfeed, the count is retained and is reset only after more sheets are placed in the input. The same rules obtain for batching. The sensors cooperate with singles, holes and doubles detectors and have their gain adjusted depending upon sheet density. Automatic threshold adjustment circuits compensate for dust build-up and component aging. Upon sheet detection, the sensing circuit threshold level is instantaneously shifted to prevent an abrupt change in intensity from the sheet covering the sensor to provide an erroneous indication of the presence of a subsequent sheet or sheets.
