Abstract: A wireless untethered device which may be an integrated circuit chip or printed circuit board having at least one integrated antenna and circuitry operatively associated with the antenna for receipt of energy harvested from space by the antenna. The antenna has an effective area greater than its physical area. A system which receives power from the harvested energy after the energy is processed by the circuitry may also be provided with mismatched impedance between the antenna and a circuit resistance.

Abstract: The present invention is a method for obtaining an electrical signal from a patient that corresponds to a meridian. The present method contemplates locating a dermal area of a patient proximate a meridian. One embodiment of the present invention comprises locating a dermal area by iteratively measuring and comparing the conductivity of a patient's skin until a significant level of conductance is indicated. A probe may then be placed in contact with the dermal area, and actuated to obtain an electrical signal therefrom. The probe tip may be specially designed to apply an appropriate amount of pressure to the dermal area to directly sense a meridian, and configured to avoid erroneous measurements resulting from misalignment of the probe or probe tip.

Abstract: The present invention provides apparatus and an associated method for remotely energizing power storage devices. Energization may preferably be effected through the use of RF energy within frequencies of the wireless fidelity standards. The remote station preferably has at least one antenna having an effective area greater than its physical area. The invention may advantageously be used on wireless fidelity products which are energized by the power storage device.

Abstract: A method of identifying an article of interest includes providing one of a plurality of RF antennas each having a non-linear element which may be a rectifying diode and being resident at a different frequency on the article of interest. One RF antenna is interrogated with RF energy of a first frequency and converts the interrogated RF energy into a reflected energy of a different frequency. The reflected energy is sensed and on the basis of the different frequency determining if a specific antenna is present. The non-linear element may be a diode and is preferably a variable non-linear element. In another embodiment, the reflected RF energy is responsive to a change in ambient physical conditions such as pressure or temperature. Corresponding apparatus is provided.

Abstract: An inherently tuned antenna has a circuit for harvesting energy transmitted in space and includes portions that are structured to provide regenerative feedback into the antenna to produce an inherently tuned antenna which has an effective area substantially greater than its physical area. The inherently tuned antenna includes inherent distributive inductive, inherent distributive capacitive and inherent distributive resistive elements which cause the antenna to resonate responsive to receipt of energy at a particular frequency and to provide feedback to regenerate the antenna. The circuit may be provided on an integrated circuit chip. An associated method is provided.

Abstract: The present invention provides apparatus and an associated method for remotely energizing power storage devices. Energization may preferably be effected through the use of RF energy from a base station, ambient energy or ultra-wide band energy. The remote station preferably has at least one antenna having an effective area greater than its physical area. The system may have an antenna and associated circuitry provided on an electronic chip such as a monolithic chip or on a printed circuit with a suitable substrate.

Abstract: The present invention provides a membrane switch which has a static layer and a flexible membrane layer disposed adjacent to each other with one or more pairs of aligned electrical poles such that the switch may assume an electrically closed position and an electrically open position. A transmitter is integrally provided within the switch, preferably in the static layer and transmits signals responsive to closing of the switch or keystrokes applied thereto. A receiver receives the signals and in cooperation with the microprocessor delivers responsive output to an electronic circuit or system. Direct physical connections between the switch and the circuit or systems are not required.

Abstract: A process for inhibiting corrosion of metal surfaces, such as steel, in a closed system which comprises maintaining in such system a composition containing a major amount of an oleaginous vehicle, such as petroleum hydrocarbon, and minor amounts of an oil-soluble hydrophilic cosolvent, such as a wetting agent, and the reaction product of substantially equimolar proportions of a dicyclohexylamine, such as dicyclohexylamine itself, and a C.sub.7 organic acid, such as heptanoic acid and cyclohexane carboxylic acid, wherein such heptanoic acid is preferably obtained by the oxidation of C.sub.7 aldehydes resulting from the oxonation of C.sub.6 alpha olefins.
