  • Patent number: 6073121
    Abstract: A method which improves check fraud prevention systems both in printing and verifying checks at their entry points. The method operates by printing on each issued check, a line of encrypted machine-only readable symbols such as a bar-code that contains all the information printed on the check, using a special, key-selectable encryption algorithm. When a check is presented to a bank teller or a cashier, a required, modified reader/decoder device connected to a computer, will read the line of encrypted data and identify a fraudulent check for rejection. The method requires primarily computer software additions and changes. Expensive replacement of existing equipment is avoided.

  • Patent number: 5992187
    Abstract: A shaft retainer device that comprises three major components: a barrel shaped housing, a leverable gripping assembly which is located inside the housing along its central axis, and a key lock in one end of the housing. When the device is locked, the gripping assembly radially grips any grooved shaft that has been inserted in the housing preventing shaft withdrawal. When unlocked by a key, the gripping assembly is spread apart, releasing its radial grip on the groove of any grooved shaft that has been previously inserted in the device. The shaft retainer will work equally well with any shaft that has a raised ridge or a stepped edge around its circumference, and can accommodate a range of shaft diameters. The device is small, light weight and economical to produce.

  • Patent number: 5894926
    Abstract: A modification of an earlier invention by this inventor for a non-spiilable liquid toothpaste dispenser, to simplify its construction and make replacement liquid toothpaste cartridges more available. The dispenser stands upright for normal use, but can be used in any orientation. It is made of rigid plastic and comprises a case, a cap, a cartridge containing liquid toothpaste, a case stand and a tooth floss holder. Inside the case top is a novel sliding valve that utilizes semicircular doors at its top. In use, a toothbrush head is pushed through a flanged hole in the top of the case, through the valve semicircular doors and into the liquid toothpaste. When the toothbrush is withdrawn, excess toothpaste is wiped off by the doors which return to their normal closed position to seal off liquid flows A plug which fits tightly in the case top entry flange, is provided in the cap to ensure no liquid leakage when the dispenser is packed. The liquid cartridge is simple and inexpensive to replace.

  • Patent number: 5686854
    Abstract: A driver circuit for high frequency transistor type switches, comprising two sections; a positive (+) drive and a negative (-) drive, both sections being supplied with a high frequency signal by a square wave oscillator source. The sections are connected in parallel to a control generated input drive signal. In the negative drive section, the input drive signal is first inverted before being processed. Each section contains precise circuits for routing a high frequency carrier signal, for increasing input drive signal power gain, for providing independent positive and negative slope control, for providing exceptionally high voltage and noise isolation to avoid transmission of harmful voltages or noise, and for delivering a positive or negative drive signal to the gate/emitter of an external transistor under drive. The invention is characterized by its high voltage and noise isolation, using few components and being small in size.

  • Patent number: 5561595
    Abstract: A three-phase ac power inverter incorporating circuits which operate to correct input power factor to near unity when connected to an ac input rectifier, while also reducing input harmonic distortion. The inverter includes a dc capacitor connected between buses, and three, four-pole inverter H-configuration bridges which output ac phases A, B and C. The cross-bar of each H-bridge is made up of an L-C filter. The inverter bridge switches, switching in an output Pulse Width Modulation mode for generating three phase sine waves, also serve to pump resonant energy between the L-C filter in each bridge and the dc capacitor. Phase A, B and C inverter bridges are pumped at the same carrier frequency, providing a continuous feed to the dc capacitor and the input rectifier. In effect, this action extends the conduction angle of the input rectifier, resulting in the input power factor being corrected to near unity. The pumping action through the L-C filters also filters and reduces the input harmonic distortion.

  • Patent number: 5548207
    Abstract: A missing phase detector circuit which monitors the ac three-phase output voltages of power equipment or sources and produces an output signal in the event a missing ac phase is detected. The circuit reduces the monitored phase voltages to low values and produces an ac ripple voltage waveform where each ripple represents a phase. An analyzer circuit examines the ac ripple voltage waveform for its zero crossings and produces a pulsed dc waveform where the width of the pulses is normally small. If any of the pulses is found to be wide, indicating a missing phase, a positive high signal is output by an AND gate. This output signal may be used to initiate illumination of a "Missing Phase" indicator or it may be used for equipment control purposes. Provision is made to prevent a false output signal when there is no input power. The circuit is not sensitive to frequency, power factor or unbalanced loads.

  • Patent number: 5505681
    Abstract: A device for athletic exercise by pulling at a resisting force. The device consists of a small cylindrical enclosure containing a number of constant force, circular wound spring assemblies, having a pulley molded to the enclosure, and having a force selector assembly connected to the enclosure which also serves to hold the device in any fixed location. A cord is wound around the pulley during assembly and its free end is attached to a pull-handle. A person uses the force selector by manually moving a spring-loaded adjustment knob through slots in the selector assembly to a slot which corresponds to the desired force level. This action causes a spring-engagement rod inside the selector assembly to engage the number of spring assemblies that will produce the selected resisting force when a person pulls at the pull handle. The device is small and light in weight. Provision is made for attachment of the device to any suitable restraining object or static equipment.
