  • Patent number: 5086289
    Abstract: A U-turn signaling attachment useful with the turn signal stalk of a motor vehicle includes a frame conformed for engagement to the stalk and a lever pivoted on one end of the frame. A cam edge is fixed to the lever to oppose one end of a push rod which, at its other end, oppposes a double lobed surface attached to the steering column. The cam edge, at its center position, is chamfered transversely to clear the push rod during fore and aft motion.

  • Patent number: 5041828
    Abstract: A photographic traffic monitoring device comprises a sensor responding to passing vehicles, for example, an induction loop imbedded in the road for monitoring traffic lights or a Doppler radar. From a signal evaluation it is determined whether a detected vehicle has violated a traffic regulation, e.g. exceeded the allowed maximum speed limit. When such a violation takes place, a camera is automatically released and the monitored vehicle is photographed. In order to collect data for statistical purposes about traffic events obtained with such devices, a memory function is provided. This function records events detected by the device, events which are not restricted to violations of traffic regulations.

  • Patent number: 5021780
    Abstract: A system for alerting passengers, particularly school children, that the particular bus they are to board is approaching. The passengers have a receiver which senses the particular signal transmitted by the approaching bus. The passengers listen for and/or watch for a visual indication that the bus is now at the location on its route where preparations should be made for boarding. The bus carries a transmitter which sends out a specific signal identifying that bus. The signal is derived from data which was entered into a signal generator in the transmitter relating to the particular school district, the route to be traveled by the bus, and the number of the bus. Each residence where the school children are waiting has a receiver which will activate an indicating device only when the specific bus identification signal is received.

  • Patent number: 5001476
    Abstract: A system for warning the pilot of a tactical aircraft in a tactical maneuver such as a dive of the point at which recovery must be immediately initiated to prevent the aircraft from descending below a minimum desired altitude monitors the altitude, descent rate and pitch angle of the aircraft, and issues a voice warning when recovery must be initiated. The system also provides warnings of dangerous flight conditions during non-tactical or common route segments of a flight such as the take-off, landing and cruise segments of a flight. Circuitry responsive to the arming of the weapons of the aircraft enables the tactical warning portion of the system and disables certain functions of the non-tactical portion of the system that may cause false warnings to be generated during tactical maneuvers.

  • Patent number: 4937559
    Abstract: An air conditioner drain blockage alarm system which is designed for application to both horizontally and vertically-mounted heating and air conditioning units, which alarm includes in a preferred embodiment, both a normally open drain line liquid level switch and a normally closed drain pan liquid level switch for sensing blockage of a drain line in both the drain line itself and in the condensate drain pan which collects condensate from the air conditioning unit. In addition to the drain line and drain pan liquid level switches, the system is characterized by an alarm which audibly indicates a high water condition in either the condensate drain pan or the drain line and a manual override switch for manually silencing the alarm. In a preferred embodiment, the system is wired through the existing thermostat in the heating and air conditioning unit to facilitate deactivating the air conditioning system by the drain pan liquid level switch when the condensate drain pan is subject to overflow.

  • Patent number: 4905235
    Abstract: In a TDMA system comprising a plurality of earth stations communicable with one another by the use of a plurality of carrier waves through a transponder of a satellite which has an available electric power level, bursts carried by the carrier waves are individually and flexibly controlled in accordance with a burst time plan so that selected ones of the carrier waves have on the satellite a total electric power level which does not exceed the available electric power level at any time. The bursts therefore may have different power levels in dependency upon scales of the earth stations, traffics carried by the bursts, and receiving conditions at the earth conditions. The selected carrier waves can be transmitted or received by frequency hopping. Such control of the power level is carried out in each earth station by the use of a combination of an attenuator (67) and an attenuation control circuit (71) operated in accordance with the burst time plan.

  • Patent number: 4839628
    Abstract: A paging receiver includes a nonvolatile memory which is readable for controlling the operation of the paging device and is capable of being partitioned into a plurality of regions. A protect means is also included for allowing modification to a selected region of the nonvolatile memory in response to an unlock signal. In a first embodiment, the unlock signal is externally applied to the paging receiver. In a second embodiment, the unlock signal is generated when a predetermined coded signal stored in the paging receiver matches a received coded signal. In a third embodiment, the protect means further includes a switch means to permit the selected region of memory to be modified while preventing other regions of memory to be modified.

  • Patent number: 4837554
    Abstract: In a preferred embodiment, there is provided a combination of circuitries and signaling lights all fed through a brake-actuation switch in electrical circuit series, such that none of the signaling lights are operative except when the brake is applied. There are two basic signaling light circuitries and lights. The first is operative when a motion indicator switch registers that the automobile is in motion, thereby closing circuit, causing those lights to be lighted or flashing. There is a separate second circuit and lights which become activated when there is no motion, i.e. when motion has terminated if the brake is still being applied. The motion switch has the alternative positions and is preferably connected to the speedometer or other conventional motion-indicator not requiring any newly manufactured motion switch.

  • Patent number: 4835515
    Abstract: This invention relates to a signal warning light device designed to be mounted on the roof of an emergency vehicle. Normally this device, in use, would appear to be a frame holding a line of lights across the top of the vehicle. However, at the scene of an emergency, under control of the driver, bars pivoted at the two ends of the frame would be automatically swiveled upward. When raised fully, the bars would appear vertical and with its vertical array of lights woudl provide approaching drivers with an advanced warning. By limiting the movement of one bar to an acute angle and not fully raising the other bar the effect of a pointing arrow or spear head would be obtained. Thus by selectively controlling the bars to be raised, traffic could be directed to proceed left or right or if the both bars were raised partially, signals to stop, slow as well as right and left may be given. Sequential flashing of the bar mounted lights would emphasize the message when directed toward the "point".

  • Patent number: 4814752
    Abstract: A washer-type machine containment pedestal tray having sensor-shutoff device for removing power from the washing machine. The invention provides a pedestal for mounting a washing machine thereon and further, that is capable of containing overflow water should the machine malfunction. The collection of water in the containment pedestal tray actuates a float which in turn trips an electrical switch to remove operative power from the washing machine motor, thus stopping the overflow. Adjunct means are also used on the switch for sounding an audible alarm to operating personnel.
