Abstract: Disclosed herein are methods and devices for assaying and concentrating analytes in a fluid sample using dielectrophoresis. As disclosed, the methods and devices utilize substrates having a plurality of pores through which analytes can be selectively prevented from passing, or inhibited, on application of an appropriate electric field waveform. The pores of the substrate produce nonuniform electric field having local extrema located near the pores. These nonuniform fields drive dielectrophoresis, which produces the inhibition. Arrangements of electrodes and porous substrates support continuous, bulk, multi-dimensional, and staged selective concentration.

Abstract: A prefabricated multi-layered flexible product which can be used as a liner for an outer shell or as a stand-alone product. A substrate fabric material is placed in parallel with a synthetic film membrane to form a two ply laminate, and with outer substrate fabric material(s) to form multi-ply laminates. A thermoplastic film is strategically placed in between the layers to enhance bonding. The laminate(s) and/or separate sheets of above materials are assembled by using a radio frequency welding process and then out into two or three dimensional forms, which in their bonded state form either a prefabricated component liner or a prefabricated stand-alone product. The form may be a glove, sock, shirt, boot/shoe, hat, jacket, pant, etc.

Abstract: There is disclosed a method and apparatus for making bladders filled with a high viscosity fluid or gel. An elastic film is placed over a cavity formed in a first mold half and vacuum drawn into the shape of the cavity. A quantity of fluid is then deposited on the first film in the cavity and the first film and fluid are overlaid with a second film. The second mold half is placed in register with the first mold half to mate opposed sealing surfaces along an outer perimeter of the cavity. The vacuum is released to expel air from the cavity between the first and second films through channels corresponding to transverse grooves formed in the sealing surface of the first mold half. The first and second films are then welded at the sealing surfaces to form a sealed bladder filled with the fluid, and the fluid-filled bladder is removed from the mold halves.

Abstract: Load driver system (10) preferably uses a microprocessor controller (20) to generate write/read signals and command signals received by a circuit at write/read and command/status input terminals (16, 17). The circuit (15) responds to the input signals and controls a semiconductor switch (11) that controls the operative state of a load (14). The circuit (15) includes a load shorted high detector (28), a load shorted low detector (29) and a load open detector (30) which are used to detect various faults and provide a predetermined sequence of logic states at the command/status input terminal (17) during read cycles implemented by the controller (20). Thus one input line (terminal 17) is used to both send commands to the semiconductor switch (11) and receive a sequence of logic states indicative of various fault modes. This permits the controller to determine which of several types of faults, if any, has occurred, while minimizing the number of controller-circuit interconnections.

Abstract: A dispenser which can deliver precise small amounts of a liquid is disclosed. The dispenser is particularly suited to applying reagents in a biological test such as an immunoassay. It includes a reservoir chamber linked to a dispense chamber via a check valve, the two chambers preferably being in the form of syringes. An outlet line leading from the dispense chamber to a nozzle includes a delay check valve (preferably a ball inside a cylindrical chamber) which allows continuous outward flow, but shuts off flow in the reverse direction after allowing a predetermined volume to pass. The process of refilling the dispense chamber from the reservoir chamber creates reverse flow in the nozzle and causes a hanging drop of liquid at the tip of the nozzle to be withdrawn.
