  • Patent number: 5966051
    Abstract: A non-linear power amplifier for amplifying a constant envelope phase modulation component of a modulation signal and combining an amplitude envelope component of the modulation signal into the amplified constant envelope phase modulation component and method for performing the same. The power amplifier receives a constant envelope phase modulation signal and transmits the signal through a pair of amplifier stages which are impedance matched together. The first amplifier stage has a fixed gain which drives an impedance load and, in turn, the second amplifier stage. A variable resistance device is connected between a base of an amplifying transistor in the second amplifier stage and electrical ground for variably controlling the gain of the second amplifier stage by variably controlling the base-to-ground resistance of the amplifying transistor in the second amplifier stage.

  • Patent number: 5964619
    Abstract: The electrical connector may include a housing, a contact, a secondary lock, a grommet, a backplate, a bolt, a contact removal tool, and a splash guard. The housing includes openings which receive the contacts. The grommets are positioned in cavities at the rear of the housing. The housing and backplate are designed so that the grommets are subjected to compressive forces in order to enhance the sealing characteristic of the grommets. As the contact is inserted, a locking tab engages an opening in the contact and prevents the contact from being removed from the housing. The secondary locks will increase the retention of the contact in the electrical connector. In addition, the secondary lock may include a feature which permits the partial insertion and retention of the secondary lock prior to insertion of the contact. The secondary lock also assures that the contacts have been properly inserted.

  • Patent number: 5966376
    Abstract: A method and apparatus for carrying out synchronous co-division multiple access (SCDMA) communication of multiple channels of digital data over a shared transmission media such as a cable television system coaxial cable, a fiber optic or copper conductor telephone link, terrestial microwave, satellite link, local or wide area network, wireless including cellur network or some combination of these media using suitable interface circuitry. The system includes modems at remote units and a central unit to receive time division multiplexed digital data arranged into timeslots or channels and uses orthogonal codes to encode each channel of multiple data and spread the energy of each channel data over a frame of data transmitted in the code domain. Spreading the data this way makes the system less susceptible to impulse noise.

  • Patent number: 5966212
    Abstract: A system includes multiple optical Fourier transform cells which simultaneously scan a device under test. The illuminated area for each Fourier transform cell is small to provide high resolution, while the number of cells is large to cover a relatively wide area and keep inspection speed high. The advantages of optical computing performed by Fourier transform optics also keeps the inspection speed high because illuminated areas are large when compared to the resolution and Fourier transforms are linear shift invariant so that optical measurements can be performed during scanning. In one embodiment, Fourier transform cells are offset from each other perpendicular to the scan direction by less that the width of an illuminated area. This provides complete coverage during scanning of a device under test. Because the illumination for the Fourier transform is collimated, the system is insensitive to focusing errors due to fluctuations in working distance.

  • Patent number: 5966202
    Abstract: Blades pivotally attached together linked to push rods and inserted into an illumination energy or flux. The blades extend longitudinally along the length of a rectangular illumination field or slit used to image a reticle onto a photosensitive substrate. The push rods are coupled to a flexure or link pivotally connected to each end of a substantially rectangular blade. The corners of the rectangular blades have a radius providing a smooth transition between blades. A frame holds the push rods in place as the blades are moved into and out of the illumination energy or flux. The push rods may be adjusted by a screw or other equivalent devices or methods. The lateral or sideways forces resulting from the movement of the blades is compensated for by the flexures or links resulting in less stress being placed on the blades. Slots placed at pivot points in the blades may also be used to facilitate movement of the blades.

  • Patent number: 5964730
    Abstract: A polymeric heat shrinkable tubular sheath for mounting about a balloon on a dilatation catheter by heat treating at a temperature which does not detrimentally effect the properties of the balloon to shrink the sheath onto the balloon. The tubular sheath is preferably heated to a temperature above body temperature, e.g. 40<100.degree. C., preferably less than 85.degree. C., to heat shrink the sheath onto the balloon. A presently preferred polymeric material is a copolymer of ethylene(75%) and methyl acrylate (25%). The heat shrinkable sheath has an inner lumen with minimum dimensions large enough to facilitate the advancement of the sheath over the exterior of a dilatation balloon without the need for a great deal of manual manipulation by the physician or other operator prior to heat shrinking.

  • Patent number: 5961092
    Abstract: A telescopic mast is provided for deployably mounting a satellite dish to a vehicle. The telescopic mast preferably is secured to a rear surface of a truck cab or other vehicle. The satellite dish is deployable via extension of the telescopic mast. The telescopic mast includes a base tube secured to the back of the vehicle and a shaft telescopically mounted within the base tube. The shaft has a dish carrier portion adapted to carry the satellite dish. The shaft is telescopically movable between a first position wherein the dish carrier portion is higher than a roof of the vehicle, and a second position wherein the dish carrier portion is lower than the roof of the vehicle to thereby protect the dish carrier portion from exposure to wind generated by movement of the vehicle to protect the dish carrier portion from road debris. A releasable locking device selectively prevents telescopic extension and retraction of the shaft with respect to the base tube.

  • Patent number: 5963776
    Abstract: A projectile, such as a bullet, is made by combining two different metals in proportions calculated to achieve a desired density, without using lead. A base constituent, made of a material having density greater than lead, is combined with a binder constituent having less density. The binder constituent is malleable and ductile metallic base material that forms projectile shapes when subjected to a consolidation force, such as compression. The metal constituents can be selected, rationed, and consolidated to achieve desired frangibility characteristics.
