Abstract: A control moment gyroscope system for delivering a target torque to a spacecraft including a rotor assembly having a rotor and a motor to spin the rotor about a rotor axis. A gimbal assembly has a gimbal for supporting the rotor assembly and a gimbal torque motor to rotate the gimbal about a gimbal axis, which is normal to the rotor axis, to generate an output torque. A control system has a sensor for determining the output torque and a processor in communication with the rotor assembly, the gimbal assembly and the sensor. The processor requests the target torque and establishes a feedback control loop to generate a torque error signal based on the output torque for bringing the output torque within a predetermined range of the target torque.
Abstract: A ring compression device including a non-rotatable substrate having a central axis. A plurality of longitudinal pressing members are arranged radially around the central axis in a plane. One end of each of the pressing members points toward the central axis. The pressing members can move toward or away from the central axis in the plane. A rotating body rotates around the central axis and parallel to the plane of the pressing members. A driving mechanism engages with the rotating body and the pressing members such that when the rotating body rotates all the pressing members move toward the central axis and apply force on a periphery of the ring.
Abstract: Featured are methods for fixing adjacent vertebrate of a spine that utilize an implant member, which preferably is arcuate. Preferred methods of the invention for stabilizing adjacent vertebrae of the spine, include forming an aperture in each of the adjacent vertebrae and inserting an implant into the apertures formed in each of the adjacent vertebrae so that the implant extends between the adjacent vertebrae and through the intervertebral space. An alternative method for fixing adjacent vertebrae of a spine includes the step of forming a common channel in and between the adjacent vertebrae and inserting an implant in the channel so as to bridge between the adjacent vertebrae. Also featured are methods for stabilizing adjacent segments of a bone, fixation systems and fixation kits.

Abstract: The present inventor devised, among other things, an exemplary information retrieval system that promises to reduce the execution of overly broad queries. One exemplary system detects overly broad queries and presents users one or more potentially relevant portions of a hierarchical subject matter classification system, instead of executing the query against the targeted database. The system also presents users the option of accessing one or more relevant documents to the query via an interface for the classification system.

Abstract: A gas turbine fuel injector includes a nozzle body having a radially inner wall proximate to an internal air path and a radially outer wall. An insulative gap is defined between the radially inner and outer walls. The inner and outer walls are adapted and configured for relative axial movement at a first interface. An inhibitor ring is disposed proximate a downstream end of the inner wall for discouraging fuel from entering the insulative gap. A second interface is formed between the downstream end of the inner wall and an upstream end of the inhibitor ring to accommodate relative axial movement of the inner and outer walls.

The transparent lid section 26 and the lens 11 are independent of each other, and the lens 11 is aligned with respect to the solid-state image sensor 24 by engaging the transparent lid section 26 with the lens holder 12 by mounting the lens 11 on the transparent lid section 26. Thus, it is possible to provide a solid-state image sensing device having high lens alignment precision with respect to a solid-state image sensor.

Abstract: The present invention relates to a structural object coated with a superhydrophobic nanostructure composite, the structural object being obtained by densely coating a surface of a solid substrate having a desired shape with a nanostructure obtained by combining a polymer having a polyethyleneimine skeleton with silica on the nanometer order, and bonding a hydrophobic group to the surface of the nanostructure, and a process for producing the structural object. The present invention also relates to a structural object coated with a superhydrophobic nanostructure composite, the structural object being obtained by removing the polymer having the polyethyleneimine skeleton from the nanostructure and bonding a hydrophobic group to the surface of the residual nanostructure containing silica as a main constituent component, and a process for producing the structural object. Furthermore, the present invention provides a method of using the structural object as a container for transferring an aqueous solution.

Abstract: This heating blower has a housing 1, a fan 2, a heater 3, and an electrostatic atomizing device 5. The electrostatic atomizing device 5 is provided in the housing 1 and discharges nanometer-size ion mist to the outside. The electrostatic atomizing device 5 comprises a discharging electrode 50, an opposed electrode 52 disposed opposite the discharging electrode 50, a cooling part 53 which cools the discharging electrode 50 to generate moisture from ambient air near the discharging electrode, and a high voltage applying part 55 which applies a high voltage between said discharging electrode and the opposed electrode to atomize water generated near the discharging electrode. Therefore, this heating blower can discharge nanometer-size ion mist to the outside without replenishment of water.
Abstract: Disclosed is a system and a training sequence setting method for performing frame synchronization in a wireless communication system. A received signal is affected by a frequency offset due to an oscillator mismatch between the transmitter and the receiver, which is one of the main causes of performance degradation of frame synchronization. In a prior Constant Amplitude Zero Auto-Correlation (CAZAC) sequence, the larger the frequency offset becomes, the more conspicuously the performance degradation of the frame synchronization occurs. The proposed training is designed to maintain a prior CAZAC property during a differential detection so as to perform a differential detection-based frame synchronization sequence insensitive to the frequency offset. As a result of performance verification, the proposed training sequence indicates that its performance of the frame synchronization is irrespective of the frequency offset, and has a better performance than the prior CAZAC sequence and random sequence.
