  • Publication number: 20090288890
    Abstract: A Solar Car that is safer and far more ecologically benign than any automobile on the road today. All of its solar panels would serve a secondary purpose besides providing power. As a thin vehicle whose chasis was no wider than forty five inches, it would need an electrical system less than ninety seven volts. Connected in series, the four or five solar panels contemplated in this patent would provide most of the power. To make sure that one could use their vehicle regularly, there would also be a supplemental plug in capacity.

  • Publication number: 20070099608
    Abstract: A system and method for wireless network planning utilizing raster data, stored and manipulated in raster data planes (204-212) and vector data (522) stored and manipulated in vector data planes (528-532). The invention increases the accuracy of network planning by simultaneously utilizing vector data planes (528-532) and raster data planes (204-212) to perform computations using vector features contained within map pixels (604). The disclosed method makes it possible to perform accurate computations such as propagation loss to vector points (602) contained within map pixels (604). Accuracy is further increased because other characteristics such as received power, elevation, and best server can be computed to the vector features rather than processing them with traditional raster resolutions.

  • Publication number: 20060077345
    Abstract: An ophthalmoscope has illuminating optics (10) for projecting a beam of light into an eye under examination and imaging optics (14) for creating an image of said eye for viewing by a user. The imaging optics comprises an objective lens system (16) and an eye piece lens system (20). Two corneal reflex stops (138 and 148) are positioned one on either side of the corneal image formed by the objective lens system. The stops block reflections from the cornea of the eye under examination over a range of distances of the ophthalmoscope from the eye. The use of the two corneal reflex stops results in the precise positioning of the ophthalmoscope relative to the eye under examination not being critical to the blocking of the corneal reflex.

  • Publication number: 20060000459
    Abstract: A flow control valve is provided. According to one aspect of this disclosure, the flow control valve includes a valve element and a support element. The valve element is configured to deflect responsive to a change in pressure difference across the valve element. The support element cooperates with the valve element to present an effective flow-through area that changes as the valve element deflects. The amount of relative engagement between the valve element and the support element changes as the valve element deflects. External vibration causes the valve element to vibrate to reduce stiction or ice buildup.

  • Patent number: 6901598
    Abstract: The present invention relates to a method and apparatus for dynamically positioning the objective lens in an optical disk drive to maintain focus despite loss of perpendicularity between the light beam and the information layer of the optical disk. Loss of perpendicularity may occur as a result of any number of factors, including irregularities in the manufacture of the disk, manufacturing tolerances and assembly of the disk drive components, bearing defect frequencies, shock and vibration. Failure to maintain perpendicularity may interference with the ability of the optical pick up unit of the drive to accurately read and write. The tilt focus mechanism of the present invention utilizes a rotary actuator that positions the objective lens in three dimensions relative to the surface of the optical disk.

  • Patent number: 6650089
    Abstract: A capacity gauge is provided that measures a selected battery capacity of a plurality of batteries in a multiple battery system. A capacity gauge and a battery current sense resistor reside on the end equipment, while the battery pack contains minimal information associated with the battery pack. Control circuits provide for proper pack selection and pack connection timing, as well as capacity gauge synchronization. Power up/down circuits provide power to control logic, the selection circuits and capacity gauge at power up, power down and battery pack removal. The system is powered by a selected battery pack after the battery pack selection is executed, and the selected battery pack monitored by the capacity gauge.

  • Patent number: 6632310
    Abstract: The present invention relates to a laminated actuator assembly and the method for making the actuator assembly. The actuator assembly is intended for use in miniature personal electronic devices, but could be used in any type of disk drive. The actuator is primarily constructed from strong, stiff, lightweight composite materials. The upper and lower planar elements of the actuator assembly, each comprising multiple composite layers, include a forward portion and a rearward portion. A flexure member, typically positioned between the layers of composite material, allows the forward portion of each planar element to pivot in unison relative to the rear portion of each planar element. In this manner, the position of an optical pick up unit or other read/write device positioned at the distal end of the actuator assembly can be adjusted relative to the surface of a data disk. The composite and flexure planar elements are formed in arrays of multiple component pieces with aligned registration members.

  • Patent number: 6487417
    Abstract: A method, executed on a simulation system (20), characterizes propagation of a radiofrequency signal (56) in a three-dimensional environment (52). The method includes forming a database (42) of propagation paths (54) of the radiofrequency signal (56) transmitted from a transmitter (58) at a fixed location (66) in the three-dimensional environment (52). The propagation paths (54) are represented by a plurality of line segments (120, 122) in the database (42). Local line segments (188) are selected from the plurality of line segments (120, 122) to establish a subset (47) of the propagation paths (54). The subset (47) includes those propagation paths (54) each having one of the local line segments (188) proximate a location (182) of a receiver (72) in the environment (52). Distinct multipath components (246) representing distinct wavefronts of the radiofrequency signal (56) are subsequently identified from the subset (47) of the propagation paths (54).
