  • Patent number: 9734687
    Abstract: A portable control system reminder device is provided that, when plugged into a vehicle accessory receptacle or socket and the vehicle ignition switch is turned on, will charge a capacitor within the device, and when the vehicle ignition switch is turned off, will discharge this capacitor through a signaling device or circuit producing an alarm signal that will remind the parents or the driver of a vehicle that a child or a pet might be inside the vehicle. A voltage regulator preferably is provided to regulate the voltage for the system and with the purpose of reducing the size of the power storage capacitor.

  • Patent number: 4766329
    Abstract: A water pump control system, such as for a boat, including a battery operated main motor-and-pump unit and a backup motor-and-pump unit. A pump turn-on transistor operates a relay to turn on the main motor-and-pump unit when the water level rises to a high level. A touch switch may be used to turn on the pump turn-on transistor independent of the water level. A pump turn-off transistor, which is turned on by the relay, keeps the main motor-and-pump unit on until the water level drops to a low water level. A backup motor-and-pump unit comes on if the main motor-and-pump unit has not come on after the pump turn-on transistor has been turned on.

  • Patent number: 4658095
    Abstract: An intercom system for a building having several occupied units served by the same entrance with a locked door. A control panel at the entrance has several call switches, one for each occupied unit. An individual two-wire line extends between the entrance control panel and a control panel in each occupied unit. A person in the occupied unit, which has been called from the entrance can release the entrance door after talking with the visitor. The system consumes electrical power only when needed.

  • Patent number: 4570040
    Abstract: An electrical switch assembly having a first switch contact member behind a housing panel which has an opening through which the shank of a bolt extends. The bolt shank carries a second switch contact member for engagement with the first switch contact member. An enlarged head on the bolt has a flat rear face for engaging the front of the housing panel around the opening. A rigid washer on the bolt shank is spaced slightly farther from the rear face of the bolt head than the thickness of the panel at the opening, so that normally the shank of the bolt tilts downward inside the housing. This establishes a first position of the second switch contact member, which is on the bolt shank, with respect to the first switch contact member. A person's finger pressing on the bolt head can raise the bolt shank to establish a second position of the second switch contact member.
