  • Patent number: 4313161
    Abstract: A system is provided that includes a plurality of processors connected to a shared storage via an asynchronous storage interface that includes various interface logic and a ring counter that performs polling of the processors for access to the shared storage. The ring utilizes a "lookahead" feature that bypasses stages in the ring to speed up responses to request signals from the processor. The logic uses the clock from the particular processor accessing the shared memory at any point in time.

  • Patent number: 4310751
    Abstract: A microfilm indexing machine for automatically generating an index for a roll of microfilm. The indexing machine can be utilized in combination with either a microfilmer equipped with blip or image count capability to generate an index while the microfilm is being created, or with a microfilm reader to generate an index for an existing roll of microfilm. The indexing machine is a microprocessor based unit that is programmed to respond to the count signals produced by the image marker on a microfilmer or the blip sensors on a microfilm reader. The microprocessor is programmed to process the count signals and automatically update the contents of one or more counters. Document identifications are made via a keyboard and are printed on a paper tape.

  • Patent number: 4310881
    Abstract: In a conditional transfer control circuit (10) for a controller (11) arranged for fetching instructions from a sequence of addresses wherein a list of instructions is stored, there is a circuit (25) for producing a first signal (C) representing a true or false condition resulting from executing an instruction in the list of instructions and a circuit (IRO) for producing applying a second signal (on lead 32 or 72) indicating whether control is determined by the first signal being true or by the first signal being false. An EXCLUSIVE NOR (or EXCLUSIVE OR) gate (30 or 70), responsive to the first and second signals, produces a condition transfer signal (on lead 18) that causes the controller to fetch a next subsequent instruction from an address other than the next subsequent address in the sequence of addresses wherein the list of instructions is stored.

  • Patent number: 4309598
    Abstract: A digital display updated by inputs from a manual control having a plurality of tactile detents. A counter is loaded with a predetermined number and then decremented at a fixed rate until the number reaches one. The fixed rate is either the program cycle time of a microprocessor embodiment or the clock time of a circuit embodiment. Whenever a detent of the control is detected, the then current value of the counter is added to or subtracted from the display and the counter is again loaded with the predetermined number.

  • Patent number: 4309599
    Abstract: The invention relates to an electronic device for measuring the time interval between the occurrence of any two successive ones of a plurality of similar events, specifically, the time interval between footsteps in jogging, running or walking, or the leg or arm motion associated with bicycling, rowing, swimming, cross-country skiing or the like, and for providing bio-feedback information to a user in the form of an alarm signal when: the measured interval is less than a predetermined low limit; the measured interval is greater than a predetermined high limit. The device includes a transducer for producing a signal at the detection of the occurrence of each event. The signals are fed to both a timing circuit and a detection circuit. The timing circuit measures the time interval between two successive events, and the detection circuit determines if the measured interval is between the high and low limits. If it is not, a signal is fed to an output circuit which then provides an audible alarm.

  • Patent number: 4303851
    Abstract: The perimeter of an area is scanned along two adjacent paths which define spacially resolved gates through which objects and people must pass to enter and leave the area. As the gates are scanned, the presence of objects and people are detected. A complete scan produces a gate signature which includes information indicative of the presence and location of objects and people in each gate during the scan. Successive signatures are compared in sequence as scans are made in order to determine changes caused by movement of objects and people in or out of the area. From this comparison an up/down counter is controlled to maintain a dynamic count of the number of objects or people in the area following each scan of the gates. The counter counts up as objects and people enter the area and counts down as they leave.

  • Patent number: 4301360
    Abstract: A time interval meter for measuring extremely short time intervals includes a timing circuit operable at a fast predetermined rate over the time interval between first and second events, and operable at a slow predetermined rate which is precisely scaled to the first rate over a time interval between the occurrence of the second event and the upper limit of a predetermined timing window. During the slow ramp period, clock pulses are counted to provide a count which is proportional to that portion of the predetermined timing window occupied by the slow ramp interval. The fast ramp time interval may then be readily attained by subtracting the slow ramp interval from the total time of the timing window. The circuit includes a control circuit, a timing circuit including a capacitor and a pair of selectable constant current sources, and a counter.

  • Patent number: 4298790
    Abstract: Reflected energy density signal as a function of distance in pulse counts determined from a side of stacked sheets is used to calculate sheet pulse counts. A working pulse range is determined from the nominal thickness range of the stacked sheets and thereafter pulse values within the working pulse range are selected. The calculated sheet pulse counts and selected pulse values are compared and acted on to develop a pair of sheet counts for each selected pulse value. The pair of sheet counts occurring at least 10 consecutive times is considered the number of sheets in the stack.
