    Abstract: Ground wires are shared between a drive-side pulley solenoid valve and a driven-side pulley solenoid valve. Therefore, when a disconnection or short circuit occurs in the shared portion, a drive-side pulley and a driven-side pulley show substantially the same behavior. As a result, changes in the speed ratio ?cvt of a continuously variable transmission are suppressed and changes in vehicle behavior are also suppressed. Therefore, it is possible to suppress the degradation of drivability during the failure of the solenoid valves involved in power transmission.

  • Publication number: 20120158188
    Abstract: A non-polarized electronic condensate overflow switch uses microprocessor-controlled low-resistance MOSFETs to connect and disconnect power to an HVAC system. The condensate overflow switch derives operational power directly from an AC main and does not need an external power supply or a separate, reference ground line, and therefore does not require configuration in a particular polarity. The microprocessor controls the turning on and off of the power MOSFETs as needed when condensate overflow is detected and also provides more efficient sensing of condensate overflow and other operations, thus minimizing the power needed by the condensate overflow switch. Such a non-polarized electronic condensate overflow switch may be installed within a drain pan, in line with an outlet of the drain pan, or at a remote location away from the drain pan.

  • Patent number: 8125108
    Abstract: A control part for causing transmission of a remote control signal from a transmission part according to a resistance of a pressure-sensitive conductive contact part causes periodic transmission of a repetition signal, when the resistance of the pressure-sensitive conductive contact part is kept constant. Thus, when an operating body is continuously held down with a constant force and the resistance of the pressure-sensitive conductive contact part is kept constant, the control part causes periodic transmission of the repetition signal having a smaller number of pulses, at predetermined intervals. With such an operation, a remote control transmitter capable of reducing power consumption is provided.

  • Publication number: 20110278954
    Abstract: An electronic apparatus for conditionally power supplying is provided. In the electronic apparatus, an external connection port is embedded on a surface of a case for electrically connecting to an external device, and includes plural exposed terminals including one power pin. First and second detection electrodes are disposed on the surface of the case and normally maintain in broken-circuit. When the first and the second detection electrodes are in a wetting condition, the first and the second detection electrodes are in short-circuit. A switch is electrically connected to a power module and the power pin. A control module detects that the first and the second detection electrodes are in short-circuit or in broken-circuit, and drives the switch to make the power module output power to the power pin when the first detection electrode and the second detection electrode are in broken-circuit.

    Abstract: In some embodiments, an apparatus includes a radiation source to output radiation after power is supplied. The apparatus also includes a power source to supply power. The apparatus includes an ambient-activated switch electrically coupled between the radiation source and the power source. The ambient-activated switch is to switch to an open position while a value for an ambient characteristic for the ambient-activated switch is at an ambient level for a surface of the Earth. The ambient-activated switch is to switch to a closed position while the value for the ambient characteristic for the ambient-activated switch is at a downhole ambient level, wherein the ambient-activated switch is to electrically couple the power source to the radiation source while in the closed position.

  • Patent number: 7557466
    Abstract: A humidity detection and power cut-off device for electronic equipment is provided. The device is connected between a battery (10) and a motherboard (40) of the electronic equipment and includes an auto protection device (20) and a moisture-triggered device (30). The auto protection device is connected between the battery and the power management module and is used to establish or cut off the connection between the battery and the power management module. The moisture-triggered device is used to detect the immediate ambient humidity and controls the auto protection device. If the moisture-triggered circuit detects that the immediate ambient humidity exceeds a predetermined critical humidity value, the moisture-triggered device outputs a trigger signal to the auto protection device. The trigger signal controls the auto protection circuit to cut off a connection between the battery and the power management module, thus to achieve waterproofing protecting for the electronic equipment.

  • Patent number: 6892751
    Abstract: A building protection system includes a switch, a transmitter, a receiver and a controllable shut-off valve disposed within the inlet line of a utility, such as water or gas, provided to a building. The switch is used to close or open the shut-off valve to stop the flow of the utility into the building. The receiver is proximate the valve, while the transmitter and switch are remote from the valve. In one embodiment, the switch is a manual switch that can be used to generate a valve open or a valve closed signal. The switch and transmitter can be wall-mounted, such as in a garage, or can be integrated into a hand-held device, such as a remote control. In other embodiments, the switch is associated with a condition sensor, such as for sensing a utilities leak or for sensing a temperature outside a certain pre-determined limit value.

  • Patent number: 6688329
    Abstract: A water feeder controller for a boiler monitors a low water cutoff sensor in a boiler and uses a feed timer to feed water to the boiler for a predetermined feed period of time. The feed timer brings the water level in the boiler well above the low water cutoff sensor. The feed timer supplies water to the boiler only if the low water cutoff sensor continues to indicate a low water level for a delay period of time measured by a delay timer. A resettable display indicates the quantity of water supplied by the water feeder to the boiler based on a feed counter incremented during water feeding. A manual feed button allows water to be manually fed to the boiler. The quantity of water manually supplied to the boiler is also shown on the display. The feed timer and delay timer are preferably implemented in software in a microcontroller in the water feeder controller. A lockout loop in the software prevents overfeeding of water to the boiler in the event of a failure of the low water cutoff sensor.
