    Abstract: A balanced radiation concentrating device used to focus radiation from a moving source onto a stationary receiver is disclosed. The primary application of such an invention relates to concentrating the radiation from the sun onto a stationary target. In such an application the device may be termed a “ganged heliostat”, which is an array of mirrors controlled by a common positioning mechanism such that each mirror reflects light from the sun onto a stationary target. The design of the device is greatly simplified in comparison to ganged heliostats of the prior art. One major improvement included in the present invention as compared to devices of the prior art is the balancing feature.

    Abstract: A housing supporting a reflective mirrored element and having an internal support structure. A stationary mounting rod passing through the internal support structure and extending from the housing for attachment to a vehicle support arm. The housing and internal support structure rotate about the mounting rod. A stabilizing unit interconnecting the mounting rod and the internal support structure for resisting rotation of the housing around the mounting rod. The stabilizing unit includes a bushing fixed to the mounting rod engaging a bearing surface of the internal support structure in a sliding friction arrangement, and a clamping member biasing the bushing against the bearing surface to impart a clamping force between the bushing and the bearing surface, so that rotation of the internal support structure about the mounting rod is resisted to reduce mirror shaking caused by vibrations and loose connections between the mounting rod and the internal support structure.

  • Publication number: 20080049365
    Abstract: An electrostatic discharge (ESD) protection circuit uses two N-channel field effect transistors (NFETs) to conduct ESD current from a first to a second supply node. During the ESD event, an ESD detection circuit couples the gates of both NFETs to the first supply node through separate conductive paths. In one novel aspect, an RC trigger circuit includes a capacitance that is charged through a resistance. The resistance involves a P-channel transistor whose gate is coupled to the gate of the second NFET. During a normal power-up condition, the P-channel transistor is conductive, thereby preventing the RC trigger from triggering if the supply voltage VDD were to rise rapidly. In another novel aspect, a novel level-shifting inverter drives the second NFET. The level-shifting inverter uses a pull down resistor to avoid snap-back and also isolates the gate of the second NFET from a capacitively loaded third supply node.

  • Publication number: 20080049372
    Abstract: A base system generates a three-dimensional magnetic flux field using, for example, a uniquely shaped magnetic material and winding arrangements that generate multi-frequency multi-directional fields such that their vector sum is the resultant of a power transference surface that sweeps three-dimensionally within the designated area. When a floating coil or winding arrangement together with the appropriate circuitry is placed in the vicinity of the field, the coupling and induction effect produces a current that flows in the conductor that forms the coil. Power can then be successfully transferred bounded by the resultant field regardless of its orientation or height. With the proliferation of Digital Signal Processing (DSP) technology in the Switched-Mode Power Supplies (SMPS) area, the electromagnetic fields can be controlled independently and therefore adaptive control becomes more feasible. This increases the benefits of three-dimensional magnetic flux generation.

    Abstract: A capacitor comprises m electrode plates that are arranged spaced apart and in parallel, where m is an integer greater than one. Even ones of the m electrode plates comprise x extensions that extend from the first side and that have a first width. Odd ones of the m electrode plates comprise y extensions that extend from the first side and that have a second width that is less than the first width. The x extensions are located between the y extensions when the m electrode plates are arranged in parallel. n first external terminals that are arranged on a first exterior surface of the capacitor.

  • Publication number: 20080049379
    Abstract: A novel lead zirconium titanate (PZT) material having unique properties and application for PZT thin film capacitors and ferroelectric capacitor structures, e.g., FeRAMs, employing such thin film material. The PZT material is scalable, being dimensionally scalable, pulse length scalable and/or E-field scalable in character, and is useful for ferroelectric capacitors over a wide range of thicknesses, e.g., from about 20 nanometers to about 150 nanometers, and a range of lateral dimensions extending to as low as 0.15 ?m. Corresponding capacitor areas (i.e., lateral scaling) in a preferred embodiment are in the range of from about 104 to about 10?2 ?m. The scalable PZT material of the invention may be formed by liquid delivery MOCVD, without PZT film modification techniques such as acceptor doping or use of film modifiers (e.g., Nb, Ta, La, Sr, Ca and the like).

  • Publication number: 20080049384
    Abstract: A cooling device is disclosed for an electrical operating means, which has a surface to be cooled. The cooling device comprises a coolant, a peripheral wall, whose interior defines a volume for the coolant, a fastening for fastening the cooling device to the electrical operating means, and a contact-pressure means. The peripheral wall has a thermally conductive contact wall with a contact face, which is designed for areal contact with the surface to be cooled. The contact-pressure means mechanically prestresses the contact wall in order to produce an areal contact pressure of the contact face against the surface to be cooled when the cooling device is fastened to the electrical operating means.
