Microbial transfer by surface contact in cleanrooms

Experiments were carried out to ascertain the proportion of microbes that would be transferred from a contaminated surface to a receiving surface in a cleanroom. To simulate transfers, microbe-carrying particles (MCPs) were sampled from the skin onto donating sterile surfaces, which were latex gloves, stainless steel and clothing fabric. A contact was made between these surfaces and a sterile receiving surface of stainless steel, and the proportion of MCPs transferred ascertained. The proportion of MCPs transferred, i.e. the transfer coefficient, was 0.19 for gloves, 0.10 for stainless steel, and 0.06 for clothing fabric. These transfer coefficients would vary in different conditions and the reasons are discussed

Using Pinch Gloves(TM) for both Natural and Abstract Interaction Techniques in Virtual Environments

Usable three-dimensional (3D) interaction techniques are difficult to design, implement, and evaluate. One reason for this is a poor understanding of the advantages and disadvantages of the wide range of 3D input devices, and of the mapping between input devices and interaction techniques. We present an analysis of Pinch Gloves™ and their use as input devices for virtual environments (VEs). We have developed a number of novel and usable interaction techniques for VEs using the gloves, including a menu system, a technique for text input, and a two-handed navigation technique. User studies have indicated the usability and utility of these techniques

Convoluted fabric for full-pressure gloves

Fabric, made of nylon ripstop coated with Neoprene, provides expansive and contractive mobility along posterior surface of glove fingers allowing maximum digital dexterity and tactility

Double gloves reduce contamination of dry box atmosphere

Pair of encased low permeability hand gloves between which an inert gas circulates reduces dry box contamination. This innovation is applicable to dry boxes using radioactive and alkali metal compounds, submicron powders, and liquid metals
