Although THz radiation is naturally emitted by hot objects, the intensity levels are too weak to be considered as a practical THz source for most applications. Photonic crystal structures are used to modify the thermal emission peak associated with the standard Planck blackbody spectral distribution so that the THz region is dramatically enhanced. The photonic crystal core is preferably combined with variable Q defect cavities and a wave guiding and power combining structure so that the radiated THz energy is efficiently collected and directed to an output antenna. Higher THz emissions are realized by embedding a finer (higher frequency) photonic crystal structure within a coarser (lower frequency) structure.

A method combines two digital images, one in the visible range and the other in the infrared range. The combined image provides an intensity band of pixels and shows detected warm objects that are superimposed on the intensity band of pixels. A user of the present invention may (1) view increased detail in the fused image of a scene and (2) have high confidence that an object in the scene is warm or hot. Hot objects collected by the infrared channel, but not visible in the visible channel may also be seen by the viewer in the fused image.

The invention relates to an improved method for producing silica aerogel in pure and flexible sheet form having effective suppression of radiative heat transport at high temperatures and increased thermal insulation property. The suppression of radiative heat transport was achieved by in-situ production of titanium dioxide nanoparticles in very minor concentrations during gelation of silica precursor, with nanoporous surface area more than 300 m<2> / g and acts as an infra red reflecting agent. When aerogel is subjected to heat during hot object insulation, it automatically turns into infra redreflecting material. Said silica aerogel can be incorporated into the inorganic fibre mat matrix individually or into two or more layers with organic sponge sheet placed in between and stitched together to form a sandwich sheet to form highly insulating flexible sheet.

The potholder is a hand protection device with a generally rectangular body having two outer surfaces, at least one layer of flexible insulating material disposed within the body, and two pockets disposed on one of the outer surfaces. The layers of the potholder provide sufficient thickness to reduce the amount of heat radiating through the potholder from the heated object to the hand. Each pocket covers about half the entire area of the potholder and is positioned so that the openings of the pockets face each other. The fingers of a hand are placed in one pocket and the thumb is inserted in the opposite pocket. The pockets retain the potholder on the hand and prevent accidental burns incurred by grazing a hot object. A number of horizontal rows of stitches are sewn between the pockets to form a crease that facilitates the folding of the potholder.

A multi-purpose trivet comprising a base and at least one insulating pad removably coupled to the base. The base comprises a support surface and optionally a peripheral wall, wherein the peripheral wall elevates the base to define an air space. The at least one insulating pad is removably coupled to the base and is adapted to be separately used for gripping and handling hot objects having a temperature of up to 580° F. when removed from the rigid base.

A protective device for use in a high temperature and liquid environment provides a glove integrally formed with a protective member in the thumb webbing region. The protective member is not readily detectable when viewing the outside of the glove. The protective member is cut resistant and constructed to protect a workman's hand as a sharp and hot object passes over the protective member contacting the outer surface of the glove.

A collapsible stand 10 comprises a first support section 12, a second support section 14, and a connecting member 16, the first support section 12 being mounted to one end of the connecting member 16 by a first axle 18 and the second support section 14 being mounted to the other end of the connecting member 16 by a second axle 20, the first and second support sections 12, 14 being pivotable relative to the connecting member 16 and the first support section 12 including two support arms 13. The second support section 14 may include two support arms 15. The stand may fold between a first open configuration (Figure 1), suitable for supporting a pan lid, a second open configuration (Figure 2) and a collapsed configuration (Figure 3), suitable for use as a trivet supporting a pan or like hot object. The stand may include a retractable bolt (22 in Figure 5) that engages with a slot (24 in Figure 5) to lock a support section in position.

The invention discloses a water-cooling backboard heat dissipating device which comprises a water-cooling backboard. A circulation loop is formed by a cooling water unit, a water pump and the water-cooling backboard through a pipeline. The water-cooling backboard comprises a heat exchanger and an air-cooling device on one side of the heat exchanger. After cooling water of the cooling water unit istransferred from a heat exchanger water inlet pipe to the heat exchanger for heat exchange, and the cooling water returns to the cooling water unit by a heat exchanger water outlet pipe. A bypass pipe is arranged between the heat exchanger water inlet pipe and the heat exchanger water outlet pipe, and a flow regulating device is arranged between the heat exchanger water inlet pipe and the bypasspipe. The invention also a control method of the above water-cooling backboard heat dissipating device. Compared with the prior art, the hot air blown by a server is directly recirculated and used after being cooled by the backboard, under the intelligent control of a PLC, the accurate cooling for a hot object can be realized, the efficiency is high, and the energy consumption is low. The specialdesign of an air duct is not needed, air flows directly from the back of the server to the front side, the airflow organization is simple and reasonable, the design and installation are simple, and the energy saving effect of airflow transportation is more remarkable.
