Abstract: A motor vehicle time speed recorder that includes a hollow parallelepiped-shaped housing, time apparatus, speed apparatus, graphical time apparatus, and graphical speed apparatus. The hollow parallelepiped-shaped housing has a front with an elongated slot and a side with an aperture. The time apparatus is responsive to the time of day. The time apparatus is disposed in the hollow parallelepiped-shaped housing and generates a time signal, so that the time of day can be monitored. The speed apparatus is responsive to the speed of the motor vehicle. The speed means is disposed in the hollow parallelepiped-shaped housing and receives a speed signal, so that the speed of the vehicle can be monitored. The graphical time apparatus graphically represents the time signal generated by the time apparatus and is disposed in the hollow parallelepiped-shaped housing, so that the time of day can be graphically represented.

Abstract: An improved electronic data recorder for use in a vehicle includes a housing having a pair of connectors. The housing encloses a modular converter, a printer module, a continuous roll of paper, a modular paper advance mechanism, conversion electronics, and memory and computation electronics. Also included in the housing are a driver code input keypad, a clock and date display, and keys for selecting a variety of functions. The data recorder connects to a free end of a rotatable odometer-speedometer cable between a rotating part of a vehicle to which the cable is attached and the vehicle odometer-speedometer. The data recorder also connects to the vehicle battery and ignition switch. The rotational motion of the cable is communicated into the housing of the data recorder by one of the connectors and from there into the modular converter. The converter converts the rotational motion into a plurality of unique electrical signals representative of mileage.

Abstract: Occupancy is monitored at a plurality of locations, such as stores, seats or chairs, hotel beds or rooms, doorway passages, service establishments, or the like, and a record is provided of the time of occupancy. The system has respective occupancy-controlled switches in electric circuits providing occupancy signals at the respective locations. These signals are fed via a transmitting circuit, which suitably selects the recorder channels, to a multi-trace recorder, and in conjunction with a clock, provides a timed record of occupancy on the respective recorder traces associated with the monitored locations. The data may be printed on a moving paper recorder strip or may be in the form of magnetic recordings on the magnetic tape of a tape recorder. Timed recordings of fault disturbances may be similarly obtained.

Abstract: A transient signal processing circuit is disclosed which includes a signal input, an adjustable threshold detector for selecting from the signal input a signal portion having at least a minimum amplitude, a peak value detector connected to the threshold detector for providing an output when the signal portion reaches a maximum amplitude, a monostable multivibrator connected to the peak value detector to introduce a time delay and thereby allow the output to stabilize, a sample and hold circuit connected to the multivibrator to record the value of the maximum amplitude, and a clock connected to the multivibrator to indicate the time at which the maximum amplitude was attained.

Abstract: A system for determining the location of the sinking of a vessel by providing a seaworthy box that is automatically ejected from the vessel at the time of sinking and that has a battery aboard the box for powering a radio transmitter that sends distress signals that enable a rescue vessel to locate the ejected box. The system employs a water-activated release mechanism and a stationary box with which the ejected box mates. When the release mechanism operates the box is ejected and at the same time the radio transmission commences. The release mechanism can also be used to release life savers and life boats. The ejected box has a printing system for registering any faults that may have occurred prior to sinking. The vessel may be provided with fire detectors, for example, and operation of a detector is registered along with the time of detector operation to thus provide a chronological log of all important events.
