Abstract: Palm cooling gloves and similar articles are disclosed which may be worn during exercise or when exposed to warm ambient temperatures. Unlike other items related to thermal exchange, the disclosed devices provide for intermittent cooling in order to ultimately increase the overall rate and magnitude of conductive heat loss from the human body. According to an example embodiment, gloves are provided with high thermal conductivity for rapid rates of heat transfer when the palm is to be cooled, and low thermal conductivity when the palm is not to be cooled. During non-cooling periods, a cooling agent is temporarily stored within a compartment located on the back (dorsal aspect) of the glove. The compartment is comprised of materials with a low thermal conductivity so that the cooling agent retains more of its cold, which allows it to be used repeatedly when palm cooling is again needed to rid the body of excess heat.

Abstract: Techniques and systems for maintaining a plasma processing kit consisting of protection and shielding elements without causing damage are introduced. The elements may be made of aluminium, polysilicon and quartz and may be coated with silicon. The surfaces of the elemants show a specified roughness. Precision cleaning and recovery of the contamined kit components of a plasma doping (PLAD) system is used, to extend the life and reusability of the components. The methods described cover the stages of inspection, pre-cleaning, mechanical processing and texturing, post-cleaning, clean-room class cleaning and packaging of the components consisting of quartz, aluminium and/or silicon. Techniques described employ the combination of a variety of means (primarily chemical and mechanical) to achieve the desired levels of cleanliness. The result obtained by methods that include Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and Laser Particle Count affirm the efficacy of these techniques.

Abstract: An analog voltage averaging circuit using active devices increases speed and resolution in analog to digital converters. The analog to digital converters combine the concepts of residue amplification and averaging to simplify the circuit implementation of high order, high speed analog to digital converters.
