Abstract: Provided are devices and methods for the collection of bioaerosols (such as viruses, bacteria, and proteins) from the exhaled breath of humans and/or animals, for the purpose of determining, for example, particle size, generation rate, diseases and interventions for particle release.

Abstract: A display system encompasses electrodes that induce a convective flow of a carrier fluid that transports a colorant species that is suspended in the carrier fluid. At least one of the convection flow, speed, and direction of the colorant species is controlled by operation of the electrodes.

Abstract: The hydraulic system safety shut off valve is a safety valve for use immediately downstream from a hydraulic pressure power supply line and before the operational control valves and in subsystems. It includes a velocity fuse having an inlet and an outlet, a surge chamber having an inlet and an outlet, and, a connecting port, which connects the inlet outlet of the velocity fuse to the inlet of the surge chamber, the chamber for accumulation as a delay source for proving between normal operating systems and surges, and such chamber with or without such combination if necessary a return line throttle or means of creating resistance where such resistance is sensed in chamber knowing the critical nature of return line pressure to normal operation, if lost triggers the release of pressure and fluid from such chamber, thereby reducing the differential pressure against spool allowing spool to over come bias moving to close thereby immediately closing off fluid supply to system.

Abstract: An electronic device having an enhanced attachment to a surface mount lamp (106) includes a circuit board (100), at least two conductive pads (102), at least two adhesive pads (104), and the surface mount lamp (106). The conductive pads (102) and the adhesive pads (104) are integrally formed within the circuit board (100). Preferably, each section of the circuit board (100) allotted for one surface mount lamp (106) has two conductive pads (102) and two adhesive pads arranged in a grid-like pattern such that similar pads are in opposing corners of the grid. The surface mount lamp (106) has two electrical leads (108), each protruding from opposing corners of a base (110) of the surface mount lamp (106). These electrical leads (108) are soldered to the conductive pads (102) in the circuit board (100). The unobscured opposing corners (112) of the plastic base (110) are partially melted and adhered to the adhesive pads (104) in the circuit board (100).

Abstract: Cellular polymeric solids are made by mixing an acidulous or acidic polymerizable medium that is polymerizable and/or cross-linkable by a free radical mechanism (e.g. an unsaturated polyester) with an effective amount of two or more acid sensitive mono- or poly-azo compounds containing the group: ##STR1## wherein Y is an acid sensitive group (e.g.

Abstract: Shaped cellular structures formed from media which are polymerizable and/or cross-linkable by free radical initiation to either a thermoplastic or thermosetting solid, process for production of such structures and the composition therefor. Process comprises preparation of composition by mixing an acid sensitive azo compound with an acidulous or acidic polymerizable medium, after which the composition is permitted to foam into a cellular structure of the desired shape.
