摘要:
An infrared emitter, which utilizes a photonic bandgap (PBG) structure to produce electromagnetic emissions with a narrow band of wavelengths, includes a semiconductor material layer, a dielectric material layer overlaying the semiconductor material layer, and a metallic material layer having an inner side overlaying the dielectric material layer. The semiconductor material layer is capable of being coupled to an energy source for introducing energy to the semiconductor material layer. An array of holes are defined in the device in a periodic manner, wherein each hole extends at least partially through the metallic material layer. The three material layers are adapted to transfer energy from the semiconductor material layer to the outer side of the metallic material layer and emit electromagnetic energy in a narrow band of wavelengths from the outer side of the metallic material layer.

An electronically-controlled locker system that utilizes distributing processing to control access to, and assignment of, a plurality of lockers in a school, workplace, fitness center, etc. The system uses a plurality of locker control units that control access to a corresponding set of lockers based on user inputs and on user/locker authorization data that is provided from a central administrator workstation. This administrator workstation communicates with a system control unit that is in communication with every locker control unit and which allows cross-communication between locker control units.

The present invention is an apparatus for monitoring the running time and cycle time of electric motors. The apparatus diagnoses fuel consumption and burner functionality in heating plants by measuring elapsed motor running time. Alternatively, the apparatus diagnoses the running and cycle time of refrigeration and air conditioning motors for the purpose of measuring efficiency and predicting failures. The Apparatus has three major components: an inductive sensor device mechanically attached to the motor; a microprocessor device connected by cable to the inductive sensor device that records time and sensor device data and retransmits it; and the central monitoring device. The microprocessor device is connected by telephone to the central monitoring device. Using historical data of fuel deliveries and consumption and the sensor-supplied running time information, the central monitoring device will predict when the fuel tank needs refilling. The data can be used to indicate a failure has occurred. In addition, the central monitoring device is able to monitor a plurality of sensor devices. This data can be used by a fuel company to schedule and optimize fuel deliveries. When used in refrigeration and air conditioning applications, the apparatus monitors the time the compressor motor is running and the time it is idle. This ratio provides the efficiency of the system and advance notice of potential failures and possible refrigerant loss.

Start-up control circuit (152) regulates the output voltage (V.sub.OS) of a power supply circuit (150). Magnetic amplifier control circuit (54) includes magnetic amplifier (42) and error detection circuitry (58, 68, and 70). Start-up control circuit (152) includes sensing circuitry (76 and 184) for generating sensing signals in response to voltage levels (V.sub.CC and V.sub.EE) in error detection circuitry (58, 68, and 70). Sensing signals indicate whether error detection circuitry (58, 68, and 70) voltage levels are sufficient to drive magnetic amplifier control circuit (54). Reset circuitry (190 and 192, and 194) associates with the sensing circuitry (76 and 184) for initially resetting magnetic amplifier (42) to prohibit output voltage (V.sub.OS) from power supply circuit (150) when the sensing signals indicate that voltage levels are insufficient for error detection circuitry to drive magnetic amplifier control circuit (54). Reset circuitry (190 192, and 194) further associates with reset control transistor (76) for controllably decreasing the reset of magnetic amplifier (42). Reset circuitry (190, 192, and 194) further associates with magnetic amplifier control circuit (54) for shifting control of magnetic amplifier (42) to magnetic amplifier control circuit (54) as voltage levels increase sufficiently for the error detection circuitry (58, 68, 70) to drive magnetic amplifier control circuit (54).

A garment hanger has a pair of clamping members. Each clamping member comprises a pair of planer end sections and a central curved section attached to the pair of planer end members. The pair of end sections of a first clamping member will touch a corresponding pair of end sections of a second clamping member and the central curved section of the first and second clamping members form an elongated oval when the pair of clamping members is placed together in a closed position. A locking device is attached to the central curved section of the first and second clamping members. The locking device secures the pair of clamping members together. When pressure is applied to the locking device, the locking device forces opens and separates the pair of clamping members. A hook assembly is attached to the locking device.

Methods and apparatus for providing a tunable absorption-emission band in a wavelength selective device are disclosed. A device for selectively absorbing incident electromagnetic radiation includes an electrically conductive surface layer including an arrangement of multiple surface elements. The surface layer is disposed at a nonzero height above a continuous electrically conductive layer. An electrically isolating intermediate layer defines a first surface that is in communication with the electrically conductive surface layer. The continuous electrically conductive backing layer is provided in communication with a second surface of the electrically isolating intermediate layer. When combined with an infrared source, the wavelength selective device emits infrared radiation in at least one narrow band determined by a resonance of the device. In some embodiments, the device includes a control feature that allows the resonance to be selectively modified. The device has broad applications including gas detection devices and infrared imaging.
