Abstract: A camera tracking system for a virtual television or video studio is provided. The camera tracking system is used to determine the position and/or orientation of recording cameras and comprises emitter devices for emitting electromagnetic radiation. The emitter devices can be mechanically coupled to the recording camera. The camera tracking system further comprises detecting devices for detecting the position of the emitter devices on the basis of the electromagnetic radiation emitted by the emitter devices, each detecting device being able to detect several emitter devices. A computer unit evaluates the electromagnetic radiation detected by the detecting devices and emitted by the emitter device, and determines the position and/or orientation of the emitter devices in relation to the detecting devices.

Abstract: The invention is directed toward a magnetic shield included in a compass-based indicator tool. The indicator tool utilizes a compass to indicate a device setting of an implantable medical device. The implantable medical device may include a target that creates an internal magnetic field for the compass to interact with. External magnetic fields, specifically earth's magnetic field, may interfere with the compass and create an incorrect device setting indication. The magnetic shield blocks the external magnetic fields from influencing the accuracy of the device setting measurement.

Abstract: Method for controlling installation of a head stack assembly in a disc drive. The head stack assembly is aligned in a head stack installation tool. A base deck assembly is advanced to the head stack installation tool, the base deck assembly having a post supporting a tolerance ring. A robotic assembly is dispatched to pick and press the head stack assembly onto the tolerance ring and post while mechanical resistance and distance traveled parameters by the head stack assembly are measured. The installation is aborted or completed in relation to the mechanical resistance encountered and the distance traveled, thus allowing use of minimum and maximum force thresholds with respect to insertion distance and assuring correct installation of the head stack assembly.

Abstract: The present invention provides a method and apparatus for utilizing spin valve magnetoresistance devices for the measurement of weak magnetic fields. The magnetoresistive element consists of a pinned ferromagnetic layer and a soft ferromagnetic layer separated by a thin spacer layer. The pinned layer may be pinned by high intrinsic coercivity, or by a neighboring antiferromagnet or high coercivity ferromagnet layer. An oscillating magnetic field is applied to the device. The amplitude of the excitation field is large enough to reverse the magnetization of the soft layer during each cycle, but small enough that the magnetization direction of the pinned layer is not much affected. In one embodiment, the applied field is applied using a current strip deposited onto the top of the other layers, so that the entire device can be produced on a single chip.

Abstract: Two Sagnac interferometers are mounted on board a ship with their axes in a horizontal plane. The axis of one interferometer is aligned in a fore-aft direction whereas the axis of the other interferometer is aligned athwartship. The output signals of the two interferometers are combined mathematically so as to cancel the effects of the ship's latitude and thus provide an output signal independent of this parameter.

Abstract: In a navigation device for land vehicles the orientation signal which indicates the direction of movement along which the vehicle is moving is measured on the one hand by an electronic compass. A further orientation signal is produced by the variation of the vehicle orientation as determined by wheel sensors. These two orientation signals comprise measuring errors. In order to determine an optimum value for the orientation from said values a digital filter unit is used which comprises low-pass and high-pass filters. The value for the orientation signal measured by the compass is presented to the input of the low-pass filter and the further orientation signal is presented to an input of the high-pass filter. The filter unit further comprises a control unit which generates a filter parameter from received orientation signals and supplies said filter parameter to the low-pass filter and the high-pass filter.
