  • Patent number: 7501770
    Abstract: A laser beam, which scans a display screen comprised of an array of picture elements. Each picture element is further comprised of a photocell connected to an LED in the presence of an electric field. The laser's intensity and or duration on selected photocells produces the desired intensity of LED illumination for that pixel. The photocells convert photons from the laser into a current flow, which is accelerated and amplified by the presence of the electric field. With quantum efficiency significantly greater than one, it is possible to create a RGB color display screen activated by a scanning laser. LEDs may be arranged in an alternating pattern of red, green, and blue to form the color display. The LED may also be monolithic in construction, coated with an alternating pattern of red, green, and blue phosphors to form the color display.

  • Patent number: 7397431
    Abstract: Antennae in which the corresponding radiative element contains at least one multilevel structure formed by a set of similar geometric elements (polygons or polyhedrons) electromagnetically coupled and grouped such that in the structure of the antenna can be identified each of the basic component elements. The design is such that it provides two important advantages: the antenna may operate simultaneously in several frequencies, and/or its size can be substantially reduced. Thus, a multiband radioelectric behavior is achieved, that is, a similar behavior for different frequency bands.

  • Patent number: 7394438
    Abstract: A wireless communication device coupled to a wave antenna that provides greater increased durability and impedance matching. The wave antenna is a conductor that is bent in alternating sections to form peaks and valleys. The wireless communication device is coupled to the wave antenna to provide wireless communication with other communication devices, such as an interrogation reader. The wireless communication device and wave antenna may be placed on objects, goods, or other articles of manufacture that are subject to forces such that the wave antenna may be stretched or compressed during the manufacture and/or use of such object, good or article of manufacture. The wave antenna, because of its bent structure, is capable of stretching and compressing more easily than other structures, reducing the wireless communication device's susceptibility to damage or breaks that might render the wireless communication device coupled to the wave antenna unable to properly communicate information wirelessly.

  • Patent number: 7355559
    Abstract: A planar small antenna and a small strip radiator are provided which have increased bandwidth. The small strip radiator has a main strip pattern and a plurality of convoluted strip patterns terminating the main strip pattern at each end. The plurality of convoluted strip patterns are arranged in mirror-symmetrical arrangement with reference to the longitudinal axis of the main strip such that one pair of convoluted strip patterns is convoluted clockwise while another pair is convoluted counterclockwise. As a result, an electrically small antenna radiator requires less metal or conductive material than conventional radiators, and also can operate without adversely affecting the radiation characteristics of the antenna.
