Various safe switching mechanisms are provided for use with electrosurgical instruments which prevent arcing between the high-energy contacts as the high-energy source is activated. The switching mechanisms generally include a pair of high-energy contacts and a pair of activation contacts. An actuator is provided which initially engages the high-energy contacts in advance of engagement of the activation contacts to prevent arcing and subsequently disengages the activation contacts in advance of the high-energy contacts as the energy source is deactivated. A method of switching power to an electrosurgical instrument while avoiding damage to high-energy contacts is also disclosed.

The invention relates to a preparation method and an application of multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric. The multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric is formed by successively arranging and laminating a metal foil reflection layer, a phase change temperature limitation layer, an interval composite membrane heat-insulation layer and a flame-retardant comfortable layer, wherein the metal foil reflection layer has high reflectivity and an enhanced heat-dissipation function; the phase change temperature limitation layer has functions of high energy consumption absorption and evenly-distributed heat conduction; the interval composite membrane heat-insulation layer has the functions of reflection insulation and even distribution of heat; and the flame-retardant comfortable layer has the functions of low-contact heat conduction, heat insulation and comfort. When the front side of the multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric is under the action of open fire and strong heat flow environment, the back side of the multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric can be kept below 50DEG C which is near the safe temperature state of the human skin, and the integral structural form and the mechanical property are stable. The natural thickness of the composite fabric is 5-15mm, the compression thickness of the composite fabric is 3-8mm, and the square meter quality of the composite fabric is 400-1500g / m<2>. The composite fabric is fire-proof heat-insulation material which is totally sealed, stuck and sewn and can be used for individual protection and environment heat insulation in special high-temperature occasions, such as fire control, military, exploration, safe escape and industry and the like.

In many processes used in fabricating semiconductors the wafer is seated on the top surface of a pedestal and heated in a high energy process step, such as plasma etching. The pedestal, chuck or platen may be cooling but the wafer gradually heats until the process can no longer continue. Where large, e.g. 300 mm diameter, wafers are being processed the temperature level across the wafer is difficult to maintain substantially constant. In this system and method the lateral temperature distribution is equalized by a heat sink structure in a chamber immediately under the wafer support on top of the pedestal. A number of spatially distributed wicking posts extend downwardly from a layer of wicking material across the top of the chamber, into a pool of a vaporizable liquid. At hot spots, vaporized liquid is generated and transported to adjacent condensation posts extending up from the liquid. The system thus passively extracts heat to equalize temperatures while recirculating liquid and assuring adequate supply. The free volume above and within the liquid, and the short distances between posts, assure adequate heat transfer rates.

A NIRS sensor device for brain monitoring is small in size, provides reliable attachment to a patient, blocks ambient light, is easy to use, is hygienic, and supports data integration with surgical and monitoring systems. The sensor device is coupled to a remote near infrared light source via a hybrid cable. Since the light source is remotely located, a source adapted for providing high energy, short pulses can easily be used so that there is less chance of interference by superficial non-brain tissues and less interference from ambient light. In addition, the remote location avoids changes in output of local light sources experienced in the prior art during hypothermia procedures (e.g., bandwidth shifts in LEDs as a result of lowered temperature). The higher energy may be achieved by the use of laser diodes as opposed to locally-mounted LEDs typically used in the prior art. The sensor device is a two-piece design comprising a reusable portion containing the photodetector(s) and a disposable portion that receives the light from the reusable portion and bends it to direct the light into the brain.
