Abstract: This invention relates to a data recording and reproduction apparatus, and a method and a system for sending out data for preparing a log file of material codes and a sending time. The video server comprises a storage means utilizing a randomly accessible storage media, and a server controller for controlling the storage means and multiple input and output ports connected to the storage means. The input port includes a multiplexer for inserting the material code to identify video source onto compressed video signals derived from video signals fed to the input ports. Video signals with their material codes superimposed thereon are recorded as video sources on the storage means. A material code is extracted from any video signal that is reproduced, and a log file of the sending data (sending time and data including material code relating to the sent-out material) is generated.

Abstract: A conventional angular rate sensor has a problem that the displacement amplitude of a drive gimbal frame is limited due to the Pulled-in phenomenon where the drive gimbal frame is attached to drive electrodes, thereby decreasing its sensor sensitivity. In an angular rate sensor, a drive frame and a driven frame are separately provided. A bending oscillation of the drive frame is transmitted to the driven frame through link beams, causing the rotational oscillation of the driven frame. The displacement amplitude of a rotational oscillation of the driven frame is not limited to provide high sensor sensitivity.

Abstract: An electrostatic microactuator, known as a “Scratch Drive Actuator” or SDA, is based on a collective set of distributed elementary SDAs of small size that are associated with one another and that integrates a large number so as to allow the addition of the forces generated by each of the SDAs in the collective set. An external mechanical prestress, formed by a homogeneous external pressure in the form of a bias voltage applied at rest to the associated SDAs, is applied to the SDAs to allow a superposition of the forces generated by the associated SDAs. This is done while communicating to an external load the entire driving force emanating from the collective behavior of the SDAs. The electrostatic attraction forces established by the bias voltage are used to calibrate an individualized prestress for each actuator involved in the collective set.

Abstract: An image from a camera is to be recorded and reversion is to be made to an image of an optional scene to reproduce an image of such scene. To this end, a CPU 20 converts image signals at a rate of 90 frames per second from a camera device 10 into parallel signals to output image signals of the usual rate of 30 frames per second. A video server 30 records the image signals from the CCU 20 on a RAID 32. If a pre-set scene is to be reproduced, the image signals are read out from the RAID 32 in the order of the original image signals to output the read-out image signals to outside.

The quadrature RF coil (48) includes a plurality of parallel rung elements (70, 72, 74, 76, 78). A pair of electrical conductive end segments (80, 82) connect the plurality of rung elements. Capacitive elements (CV, CA) interrupt a central rung element and the end segments. Preferably, the capacitive elements (CV, CA) are arranged in a high-pass configuration such that the two highest resonant modes, an odd mode (90) and an even mode (92), are tuned to have peak responsivity to a common imaging frequency. The odd mode (90) is responsive to magnetic fields which are normal to the coil (48), while the even mode is responsive to magnetic fields which are parallel to the coil (48) and perpendicular to the main magnetic field.
