Abstract: A number of wave correction filters are disclosed which respond to power surges or spikes outside the intended frequency and/or voltage for a load device. The circuits respond to such undesired frequencies and voltage levels by sensing and separating them from the desired voltage and frequencies and connecting the energy from such undesired voltages and/or frequencies to resistors where it is dissipated as heat. In this way, the resulting energy is prevented from distorting the input voltage to the load device. It is also retained in the filter and prevented from traveling through a ground connection to pollute other related circuits.

Abstract: The invention provides a helical antenna to broadcast a signal from an input line. The antenna includes a base plate and a dielectric rod mounted on the base plate. A conductive helix, surrounds the dielectric rod, and the rod has a pitch angle of at least 12 degrees. A matching network is connected to the conductive helix, to match an impedance of the conductive helix with an impedance of the signal.

Abstract: A parallel fed colinear dipole array antenna for broadcasting and receiving a signal of a selected wavelength. The antenna comprises a plurality of elongate dipole antennas attached end-to-end in a linear array. A power divider divides and transmits a signal in parallel to each of the dipole antennas. The linear spacing of the dipoles is correlated with the dimensions of the dipoles and the selected wavelength, such that the signals of the dipole antennas interfere with each other when broadcast, so as to focus signals which propagate substantially perpendicularly to the linear array, and to diminish other signals.

Abstract: A waveform correction filter is connected into an alternating current power line to absorb and remove various forms of power pollution, including high-frequency spikes, surges and other forms of high-frequency oscillations, such as those which result from switching inductive loads on and off. The waveform correction filter of the invention includes a fuse and a coaxial amorphous toroidal inductor connected between a power line and neutral with a low-pass filter connected in series with the fuse and coaxial amorphous toroidal inductor. The filter includes a capacitor, a varistor connected in parallel with said capacitor, and a magnetic core inductor connected in series with each other and in parallel with the capacitor and said varistor. A lamp may be connected in series with the resistor and the magnetic core inductor or across the resistor. Various arrangements are shown for connecting a plurality of the waveform correction filters into single phase or three-phase Wine or delta circuits.

Abstract: A method of extending discharge lamp life includes slowing electrode deterioration by powering the discharge lamp so that a lamp arc current having a reduced crest factor results, either by retrofitting an existing discharge lamp system with a waveform conditioning module, by powering the discharge lamp with a ballast producing a squarewave-type waveform, or by slowing deterioration of an emissive coating on a discharge lamp electrode by such means as preheating the electrode prior to use in order to bond the emissive coating on the electrode. A discharge lamp system includes a discharge lamp and components operatively coupled to the discharge lamp for supplying a lamp arc current to the discharge lamp that has a reduced crest factor and controlled lamp watt loading, such as a ballast configured to supply a lamp arc current with a waveform that is substantially a squarewave or an existing ballast retrofitted with waveform conditioning circuitry that causes the lamp arc current to have a reduced crest factor.

Abstract: A timing control circuit for use in automatically and intermittently operating electrical appliances, such as lamps, for security purposes in homes, offices and other buildings. The circuit is adapted to plug into a conventional wall socket and to receive conventional two-prong plugs of electrical appliances. When enabled, the circuit intermittently applies power from the wall socket to a connected electrical appliance so that the appliance is turned on and off automatically over some period of time. The circuit includes manually operable switches to enable a user to select the intermittency or on-off pattern of operation of the appliance and the period of time over which such pattern is developed. Controlling turn-on and turn-off of lamps, radios, or the like gives the appearance of occupancy of a dwelling and therefore discourages would be burglars and prowlers.

Abstract: A wearable heart rate monitor includes a wrist cuff or strap suitable for being placed about the wrist of a person, a display housing mounted on the wrist cuff, a pressure transducer element also mounted on the wrist cuff at a position to cover the radial artery when the wrist cuff is placed about the wrist, and logic circuitry disposed in the display housing for producing an indication of the pulse rate of the individual wearing the wrist cuff. The pressure transducer element detects expansion and contraction of the radial artery and applies a signal to the logic circuitry which then produces a visual display of the pulse rate.

Abstract: A solid state timer device useable for security purposes in homes, offices and other buildings. The device is engineered to plug into a conventional wall socket and to receive the inlet plugs of appliances such as lamps and radios. The device is programmed to connect intermittently, in the desired sequence and for desired periods, power from the wall plug to the electrical appliance in question so that the same will go on and off automatically over a period of time and then will remain off for another period of time before resuming the said subsequence of operation. Such switching of lamps and radios on and off, for example, will create the illusion of occupancy and is intended to discourage would-be burglars and prowlers.
