Abstract: A mobile device includes an adjustable impedance matching network coupled between a power amplifier and an antenna and has an adjustable impedance element. An impedance sensor is coupled between the power amplifier and adjustable impedance matching network. A processor is configured to a) calculate a corrected antenna load impedance based upon a sensed impedance at inputs of the impedance matching network and a current value of the adjustable impedance element, and b) determine a new value for the adjustable impedance element based upon the corrected antenna load impedance. The processor is also configured to c) set the adjustable impedance element to the new value, and d) sense a new impedance at the inputs and determine if the sensed new impedance is within a threshold value of the power amplifier impedance, and repeat steps a), b), and c) if the sensed new impedance is not within the threshold value.

Abstract: A composite substrate includes first and second substrate layers with a polyurethane foam layer there between. The foam layer preferably penetrates into the first and second substrate layers to form very strong bonds without the need for intervening adhesives. A component of the foam material formulation is natural oil. The resultant composite substrate thereby has excellent load-bearing properties. It can also be manufactured with lower cost capital equipment and a reduced impact on the environment relative to substrates using more conventional foam formulations and bonding processes.

Abstract: The invention describes biological assays in which hydrogen peroxide is used as an oxidizing agent, or wherein hydrogen peroxide is used to oxidize a dye or other intermediate to generate a detectable species. The stability of the hydrogen peroxide in the presence of at least one other enzyme which decomposes hydrogen peroxide is enhanced by the addition of a suitable inhibitor for the enzyme and the inhibitor does not substantially inhibit enzymes used in the assay. When catalase is the enzyme to be inhibited, catalase inhibitors that can be used in the biological systems include hydroxylamine sulfate. The enzyme inhibitor can be incorporated in an integral analytic device.

Abstract: A mechanism used to control the vertical height as well as fore-aft position of a vehicle seat while presenting a minimum height profile when adjusted to minimum vertical elevation. The seat is connected to a pair of rails, one stationary and one reciprocable. A seat is affixed to an attachment bracket which is connected to the reciprocable rail by a vertical height adjuster comprising a vertically oriented screw jack which may be positioned to selectable heights by a motor. The fore-aft relationship of the rails may also be selectively adjusted by a motor driving a horizontally oriented screw jack. Both screw jacks incorporate a screw connected to a helical gear engaged to a worm gear. The worm gear is driven by a remote motor through a flexible drive cable. Both screw jacks present a structure which offers a minimum height profile when the seat is positioned at minimum vertical height.

Abstract: A patient signalling system comprising a touch sensitive capacitive transducer adapted to be conveniently and comfortably placed with a patient afflicted with an illness or paralysis rendering him incapable of producing any significant manual force or dexterity, a flexible electrical cable of appreciable length connected at one end to the transducer, and a circuit located remote from the patient and connected to the other end of the cable for converting a change in capacitance of the transducer when touched by the patient into an electrical signal for causing operation of an appliance such as a signalling or communication device connected to the circuit. The circuit includes an input stage in the form of a high input impedance semiconductor device, a direct coupled a.c. amplifier, a resistive coupled a.c. amplifier, and a d.c. semiconductor switch. The system can include provision for patient electrical isolation and low battery voltage indication.
