摘要： A detonator for an explosive material is described. The detonator includes a semiconductor bridge, coupled with the explosive material, including thermal feedback mechanism is provided via one or more thermistors. An exemplary mechanism includes a semiconductor bridge with a polysilicon resistor and a pair of thermistors. The two thermistors are disposed to be substantially close to or sandwich the polysilicon resistor. When the temperature surrounding the polysilicon resistor is getting upwards, the temperature surrounding the thermistors is equally going up. When the temperature reaches a critical point, but below the threshold of the polysilicon resistor, the resistance of the thermistors drops suddenly or drastically, causing the current driving up the temperature of the polysilicon resistor to divert through the VOX temp resistors. Subsequently the current going through the polysilicon resistor is reduced, causing the temperature to drop downwards.

摘要： A light converting optical system employing a planar light trapping optical structure illuminated by a source of monochromatic light. The light trapping optical structure includes a photoabsorptive layer including quantum dots. The photoabsorptive layer is configured at a relatively low thickness and located between a broad-area optically transmissive surface configured to reflect light using a total internal reflection and an opposing broad-area reflective surface formed by a thin sheet of material configured to diffusely reflect light. The opposing surfaces confine and redistribute light within the light trapping structure, causing multiple transverse propagation of light through the photoabsorptive layer and enhanced absorption and light conversion. The light trapping optical structure may further incorporate an array of lenses or other optical elements located on a light path between the light source and the photoabsorptive layer.

摘要： A light converting optical system employing a planar light trapping optical structure. The light trapping optical structure includes a monochromatic light source, a light guiding layer, a lenticular lens array incorporating a plurality of linear cylindrical microlenses, a broad-area reflective surface, and a generally planar photoresponsive layer located between the lens array and the reflective surface. The photoresponsive layer is configured at a sufficiently low thickness to transmit at least a portion of incident light without absorption in a single pass. A portion of the unabsorbed light is trapped within the light trapping optical structure and redirected back to the photoresponsive layer.

摘要： The solar desalination and power generating system is a hybrid system combining a Fresnel solar concentrator with a solar desalination still, and further including at least one concentrating photovoltaic cell for simultaneously generating electrical power. The solar still includes an absorber base, at least one sidewall, and a hollow cover. The hollow cover has an inlet port for receiving seawater, which passes through an interior of the hollow cover and exits through at least one outlet port into an open interior region of the solar still. At least one collection duct collects pure water condensate. A vacuum pump selectively lowers the pressure within the open interior region of the solar still. The solar still is suspended above a linear Fresnel reflector array such that the at least one concentrating photovoltaic cell, mounted to a lower surface of the absorber base, is positioned at a focal line thereof.

摘要： A solar concentrator device comprising a solar concentrator element comprising a radiation transmissive surface, a radiation absorptive material and a radiation concentrating/collection point and disposed on the incident radiation side thereof a recapture element for recapturing at least a portion of radiation lost from the concentrator element has improved solar radiation collection efficiency by reintroducing recaptured radiation into the concentrator element or by propagating said recaptured radiation through the recapture element to a radiation concentration point associated with the recapture element. It has been found that planar elements having a grooved or corrugated outer surface make for very good recapture elements for planar concentrator elements.
