A lighting assembly for an interior rearview mirror assembly of a vehicle includes an illumination source, a reflective element and a lens. The illumination source is operable to radiate radiation including visible radiation and infrared radiation. The radiation from the illumination source impinges on the reflective element. The reflective element reflects reflected radiation toward the lens. The reflective element is adapted to at least partially transmit the infrared radiation so that reduced reflection of the infrared radiation occurs toward the lens. The lens may include an optical element which functions to substantially transmit the visible radiation through the optical element and the lens while at least partially reflecting the infrared radiation generally away from the lens.

Appliances with brushless motors

A portable electric appliance (1, 23) such as a hand held hair dryer uses a brushless electric motor (13, 25) in combination with a secondary fan assembly (14) and / or an air scoop (24) to redirect air toward the motor (13, 25), to maintain a cool operating temperature. The appliance includes a control circuit (50, 80, 94, 102, 110) for controlling the brushless motor (13, 25) and other appliance features. The control circuit and the coil windings (21) of the brushless electric motor are designed to run the appliance at a relatively low current to accommodate a higher operating voltage, thereby operating at a low wattage for reducing extraneous or waste heat. This facilitates placement of the control circuit in a small, portable appliance, and may enhance operation of the appliance in certain modes such as a hair dryer “cool shot.”

Method and device for safe and controlled delivery of ammonia from a solid ammonia storage medium

Solid metal ammine complexes are applied for safe and high-density storage of ammonia to be released for use as reducing agent in selective catalytic reduction of NOx in exhaust gases. The compositional formula of the metal ammine complexes is M(NH3)nXz, where MZ+ represents one or more metal ions capable of binding ammonia, X represents one or more anions, n is the coordination number (from 2 to 12), and z the valency of the metal ion (and thus the total number of compensating anion charges). Ammonia is released by generating a reduced gas-phase pressure of ammonia inside the container, which is below the equilibrium desorption pressure of ammonia at the operating temperature of the storage material thus enabling the unit to be operated is a safe manner with lower operating temperature and pressure.

Diaphragm valve for high-temperature precursor supply in atomic layer deposition

A diaphragm valve includes a heating body that thermally contacts a valve body of the valve and extends proximal to a diaphragm of the valve opposite a valve passage through which medium flows. The heating body forms a thermally conductive pathway between the valve body and the diaphragm that facilitates maintaining an operating temperature at the diaphragm. When used in an atomic layer deposition (ALD) system, the diaphragm valve inhibits condensation or freezing of high-temperature ALD precursor gases in the valve passage. A plunger including thermally insulating features preferably extends through a central opening in the heating body to operably couple a valve actuator to the diaphragm. In some embodiments, a thermally resistive member may be interposed between the valve passage and the actuator for attenuating heat transfer between the valve passage and the actuator.

Fluid treatment process and apparatus

A water treatment process whereby heat is used and recaptured to pasteurize water and or sewage effluent. Contaminated waters are partially treatable utilizing bacterial and chemical processes; however some bacteria (e.g. Cryptosporidium and Giardia) are resistant to chemicals. The present process raises the temperature of the water to a desired pasteurization temperature and for a corresponding required length of time to destroy pathogens and viruses. A heat exchanger is employed to use the waste heat from the pasteurization tank to pre-heat the fluid entering the tank. After the initial heating of the tank, the pre-heating reduces the required heat to maintain the temperature of the tank. Make-up heat increases the temperature within a small temperature range. The make-up heat may be waste heat from a separate process.

Light emitting assembly and method thereof

A mount connects a light emitting device, such as a laser diode assembly, to an optical bench. The mount may include a thermoelectrical module coupled to a sub-element of a heat exchanger extending through an opening formed in the optical bench. The thermoelectrical module acts as a heat sink to draw heat outwardly from the laser diode and cool the same. The heat sink enables the laser diode to transmit heat thereto such that substantially all of the heat generated by the laser diode sinks to the heat exchanger. As such, the laser diode transfers virtually no heat to the optical bench so the optical bench is free of deflections or distortions resultant from the heat generated during generation of the laser beam.

A method and apparatus for controlling the electrical power applied to an electrically driven oxygen separation device having one or more composite membrane elements to separate oxygen from an oxygen containing feed. The composite membrane elements have a resistance increasing during the operation thereof that would act to reduce oxygen output if applied voltage were held constant.

Once this level is obtained, the electrical potential difference is maintained at a constant level and the electric current being drawn and the oxygen output is allowed to decay to a predetermined low level after which the element or elements are replaced.
