  • Patent number: 6817569
    Abstract: A guidance seeker system for a projectile includes a plurality of photoconductive sensing elements symmetrically disposed about a central axis of the projectile. When a target is illuminated with a light source, a lens transmits light reflected from the target to one or more of the photoconductive sensing elements. Dependent on which photoconductive sensing element is irradiated, a variance between the line of flight of the projectile and the target is determined. A voltage impulse resulting from irradiation of the photoconductive sensing element triggers actuation of a course corrector, such as a diverter, to nudge the line of flight of the projectile to increase the likelihood of the projectile reaching the desired target. This guidance seeking system is particularly effective when the target is designated with a pulsed laser.

  • Patent number: 6742461
    Abstract: An extensible table with its unextended tabletop formed by leaves that are slidably fixed on the supporting frame of the table. The sliding leaves are moved away from each other to reveal a hidden extension leaf that is raised by momentarily applying an initiating downward force. The extension leaf raises itself to the same level as the sliding leaves are to form an extended tabletop. The extension leaf is moved down to its original level by an applied downward force and allows for the sliding leaves to be slid toward each other to form the unextended tabletop. Latching is accomplished by a latching pin. The first end of the latching pin is in a pin housing. This allows the second end of the latching pin to move in the groove of the grooved block. A spring in the pin housing holds the second end of the pin in the grove.

  • Patent number: 6724489
    Abstract: A system for measuring the spatial dimensions of a three-dimensional object employs a lens and at least two detectors. The combination of which defines two or more object planes. The combination of the lens and the detectors define an optical axis that is normal to the object planes and passes through a focal point of the lens. At least a first and a second photodetector are optically aligned with the object through the lens. The first and second photodetectors or array of detectors are further parallel with the surface but have differing elevations relative to that surface. In addition, the first and second photodetectors are capable of motion relative to said object. Electrical output from the first and from the second photodetectors is provided to a processor that determines a distance of the object from the lens and thereby a height of the object. This system is particularly suited for measuring the spatial dimensions of solder balls mounted to a surface of a ball grid array (BGA) electronic package.

  • Patent number: 6689268
    Abstract: A composite material includes a structural carrier layer and a relatively thin metal foil layer separated by a release layer. The release layer, that may be an admixture of a metal such as nickel or chromium and a non-metal such as chromium oxide, nickel oxide, chromium phosphate or nickel phosphate, provides a peel strength for the metal foil layer from the carrier strip that is typically on the order of 0.1 pound per inch to 2 pounds per inch. This provides sufficient adhesion to prevent premature separation of the metal foil layer from the carrier layer, but easy removal of the carrier layer when desired. Typically, the metal foil layer is subsequently bonded to a dielectric and the carrier layer then removed. The metal foil layer is then imaged into circuit features in the manufacture of printed circuit boards and flexible circuits.

  • Patent number: 6679794
    Abstract: An apparatus (40) is used to implement a method for training a person to accomplish a basketball shot. A lower body positioning member (60) is located in front of a leg area of the person when that person is in a position to attempt the shot. When the person so attempts the shot, the lower body positioning member restrains forward rotation of the person's leading shin. An upper body positioning member (68) is located in front of a torso area of the person. When the person attempts the shot, the upper body positioning member restrains downward rotation of the person's shooting arm. In a repetitive process, the person is provided with a basketball and shoots the basketball at the goal. By this repetitive process the person learns to accomplish the shot without excessive rotation of the lower leg and upper arm.

  • Patent number: 6646507
    Abstract: The main difference between the power booster amplifier according to this invention and state of the art class D amplifiers is in the connection of a load between a power supply and a switching half bridge which is supplied from a bridge capacitor. The switching half bridge operation is controlled by pulse-width modulated control signals. Thereby, it is possible to completely eliminate both input and output filters which are required in state of the art class D amplifiers. It is also possible to achieve several times higher power at the load due to the additional supply from the bridge capacitor for the switching half bridge. The conducted and radiated EMI noise is significantly reduced in comparison with state of the art class D amplifiers. This embodiment provides a low price, small size and low EMI noise level.
