  • Patent number: 5471492
    Abstract: A broadband matching network closely matches the output impedance of a broadband amplifier to the input impedance of a laser over a broad frequency band to facilitate efficient transfer of power therebetween. As a result, the broadband amplifier does not have to generate high output power levels that cause intermodulation distortion. The matching network includes a pair of matching transformers having toroidal cores and a filter circuit.

  • Patent number: 5463689
    Abstract: An off-premises method and apparatus for the interdiction of unauthorized channels of a broadband cable television signal includes common circuitry for adjusting the amplitude and equalization levels of the broadband CATV signals and one or more subscriber modules for generating jamming signals of different frequencies which are used to interdict one or more unauthorized channels. Each subscriber module is associated with a subscriber and is programmable and addressable to adjust the jamming parameters of that subscriber independently of other subscribers. Each subscriber module circuit comprises a plurality of latches, each of which is associated with one of a plurality of digital to analog converters. Each of the digital to analog converters drives one or more frequency agile oscillators with its analog output to generate the jamming signals.

  • Patent number: 5446992
    Abstract: A rodent bait station for the eradication of rats, mice and other rodents and vermin, which is safe for use around children, pets and other non-target species. The bait station includes an outer housing and an inner housing slidably movable with respect to the outer housing. The inner housing is movable between open, closed, and extended positions. When the inner housing is in the extended position, poisonous bait can be loaded into the bait station. When the inner housing is in the open position, rodents can access the poisonous bait located in the bait station. When the inner housing is in the closed position, the poisonous bait is substantially sealed within the bait station. The inner housing automatically moves from the open position to the closed position in response to being lifted off a supporting surface, thereby preventing the exposure of the poisonous bait to non-target species.

  • Patent number: 5444867
    Abstract: An adapter unit for adaptively supplying a portable radio unit with electric power is disclosed. When the portable radio unit being not powered by a rechargeable battery attached thereto or being not in a communication state is connected to the adapter unit, the first power supply circuit of the adapter unit supplies the rechargeable battery or the portable radio unit with power. When the portable radio unit being in the communication state is connected to the adapter unit, the second power supply circuit of the adapter unit supplies the portable radio unit through the rechargeable battery with power. Power supply capacity of the second power supply circuit is larger than that of the first power supply circuit.

  • Patent number: 5444736
    Abstract: A radio communication apparatus comprises a detecting circuit for detecting a change of a received frequency of a radio communication channel during a communication and outputting a digital detection signal, a pulse width modulating circuit, and a smoothing circuit. The pulse width modulating circuit pulse-width modulates a pulse signal having a predetermined frequency in accordance with the digital detection signal output from the detecting circuit. The smoothing circuit smoothes the pulse-width modulated circuit output from the pulse width modulating circuit and generates an analog control signal. A transmission local oscillating frequency is controlled in accordance with the analog control signal.

  • Patent number: 5444449
    Abstract: A satellite system facilitates communications between earth stations and both geostationary satellites and non-geostationary satellites in an orbit at a lower altitude than that of said the geostationary satellites by preventing the non-geostationary satellite from transmitting signals that might possibly interfere with signals transmitted by the geostationary satellites. The non-geostationary satellite includes position acquisition subsystem for determining the position, and in particular the latitude, of the non-geostationary satellite relative to the surface of the earth. A data processor determines a forbidden band of locations on the surface of the earth all possible geostationary satellites and the non-geostationary satellite, at its determined position, are separated by less than a specified minimum discrimination angle.

  • Patent number: 5442375
    Abstract: A window for use in a monochrome LCD or gas plasma display is provided with a "Color Finder" button for identifying each of 16 (or 64) colors to be displayed. By activating a button in the window, the indicated gray scale for that color is temporarily inverted so that it oscillates between its current value and its most opposite value. This technique "flashes" the associated shade of gray on the screen, thereby informing the user that the color is in use on the screen and pinpointing just where the color is being displayed. Consequently, this invention allows the computer user to limit gray scale adjustments only to those that are needed.

  • Patent number: 5440179
    Abstract: AS uninterruptible power supply (UPS) is disclosed in which AC line power is used to charge back-up battery and to operate a load during a stand-by mode of operation of the UPS. In the back-up mode of operation when AC line power is not available, the battery is used to supply power to the load. The UPS is implemented with only one inexpensive high frequency transformer and a single bi-directional power converter. Thus, the UPS of the present invention is lower in cost and complexity than such UPSs known in the prior art.

  • Patent number: 5439312
    Abstract: A method and apparatus for applying a traffic stripe having improved reflectivity includes a vehicle having an apparatus for applying the traffic stripe, an applying assembly for dispersing a reflective material over the traffic stripe, another applying apparatus for applying a releasing agent, and a deformation apparatus disposed rearward thereof for forming interval grooves in the traffic stripe. The application of the releasing agent directly onto the traffic stripe or onto the deformation apparatus prevents the freshly applied traffic stripe from lifting off the road surface and adhering to the deformation apparatus.

  • Patent number: 5434074
    Abstract: A herpes virus proteinase has been found to be encoded by a member of a family of four nested genes in simian cytomegalovirus. Another member of the nested genes encodes the assembly protein precursor, which is a substrate for the proteinase. Homologous genes are found in other herpes viruses. Cleavage sites recognized by the proteinase are identified in cytomegalovirus and are found to be highly conserved in other herpes viruses. Substrates, inhibitors, assay kits, and methods of assaying are provided which rely on the proteinase and its activity.

  • Patent number: 5430731
    Abstract: In a radio tele-communication system of this invention, at least one radio frequency is shared by a plurality of base stations and a plurality of mobile stations, a signal transmitted at the radio frequency has a time frame constituted by a plurality of time-divisionally multiplexed time slots, and time intervals for detecting timing shifts are set between the plurality of time slots. In at least either the base stations or mobile stations, a communication timing shift in a time slot currently used for communication is detected from a reception state in one of the time intervals for detecting timing shifts, and the communication timing of the corresponding time slot is corrected in cooperation with a station, with which communication is performed, on the basis of the communication timing shift detection result.
