摘要： A portable electric appliance includes a housing, an electrically operable element positioned within the housing, a transmitter adapted to transmit a beam of radiation, and a receiver responsive to the beam of radiation. The transmitter is positioned external to the housing, and the receiver is positioned to receive the beam of radiation. The electrically operable element is de-energized in response to the beam of radiation being blocked or interrupted. A method adapted to disable a portable electric appliance includes transmitting a beam of radiation from a transmitter on the portable electric appliance, receiving the beam of radiation by a receiver on the portable electric appliance, and de-energizing an electrically operable element associated with the portable electric appliance in response to the beam of radiation being blocked or interrupted.

摘要： A portable heater incorporates a housing, heating element, outlet for heat generated by the heating element, and diagnostic testing capabilities that test for defective or abnormal conditions of various safety features and report their status. The features include an object sensing or cover detect function, which operates to disconnect the heater from the primary power source in the event an object is detected that may obstruct the heater outlet, a tilt sensor, which detects whether the heater has been tilted, a fuse, and a positive temperature coefficient (PTC) breaker. The diagnostic testing function preferably receives power directly from the primary source of power to enable the status of the tests to be displayed whenever the heater is plugged in. Light emitting diodes preferably provide backlighting to icons representing the various features to indicate their status to the user.

摘要： An electronic control circuit for use with a heater, a fan, a humidifier, a cooking apparatus, or any device utilizing a power mode switch and a condition sensor, and optionally time-automated switching of modes of operation. The circuit includes a single control switch to switch between operational modes and to select a level of operation. The circuit preferably includes an application-specific integrated circuit, to provide circuit logic. The single control switch, preferably a push-button switch, selects a mode of operation for a household appliance controlling a local environment, e.g., a humidifier or a heater, and the level of operation. The unit operates in the selected operational mode at the selected level, as indicated by either an energized light-emitting diode or a digital display. Operational modes may include a timed mode, a manual mode, and/or automatic mode for regulation of the environmental condition with a sensor included in the circuit.

摘要： A downspout drain filter includes a housing and a filter media. The housing defines an internal cavity, an inlet to the internal cavity along a top of the housing, and an outlet from the internal cavity along a bottom of the housing. The filter media is disposed within the internal cavity. The filter media divides the internal cavity into an upper chamber and a lower chamber. The filter media is configured to trap debris in the upper chamber from fluid flowing downward through the internal cavity. The filter media is permeable such that the fluid flows from the upper chamber to the lower chamber.

摘要： A heating pad controller is provided which varies the duty cycle during which power is applied to a heating pad heating element. In one embodiment according to the present invention, an oscillator circuit is used to vary the off-time of the duty cycle, with the on-time portion being fixed. User control of the off-time is provided by way of a rotary control knob connected to a potentiometer. The potentiometer is part of the oscillator circuit and is used to vary the resistance through which a capacitor in the oscillator circuit charges up. The output of the oscillator circuit is used to control the gate of a silicon controlled rectifier (SCR), which acts as a power switch through which power is applied to the heating element. During power up, the oscillator circuit is overridden and a continuous control signal is applied to the SCR to provide constant power to the heating element to thereby achieve rapid heating. In an alternative embodiment according to the present invention, a digital heating pad controller is provided to vary the duty cycle during which power is applied to a heating pad heating element. User control is provided by way of a number of switches which are used to select one of a number of operating temperatures. Additionally, when the heating pad is first turned on or when the desired temperature setting is increased, continuous power, i.e., 100% duty cycle operation, is initiated in order to rapidly heat the heating pad to the desired temperature. Similarly, when the desired temperature setting is decreased, no power is applied to the heating element, i.e., 0% duty cycle operation.

摘要： A catch basin system includes an upper housing and a lower housing. The upper housing defines an upper region of a first conduit and an upper region of a second conduit. The first and second conduits are aligned along a first axis. The lower housing is removably secured to the upper housing. The lower housing defines a lower region of the of the first conduit, a lower region of the second conduit, a third conduit disposed below the first conduit, a fourth conduit disposed below the second conduit, and a sump disposed between the third and fourth conduits and below the third and fourth conduits. The third and fourth conduits are aligned along a second axis. The first, second, third, and fourth conduits are each in fluid communication with sump.
