摘要： A system for detecting the position of a person in a pool (2), comprises a transmitter positioned in the pool (2), a receiver (20) for receiving the signal from the transmitter (16a-16f) and generating a stimulus, with the receiver (20) being positioned on the person. The pool (2) may contain a lap lane (4) and a series of transmitters (18a-18f) traverses the center of the lap lane. The receiver (20) may comprise a disc member with a suction means for attaching to a person. In another embodiment, the transmitter and the receiver are configured as a single unit (42). A method of detecting the position of the swimmer within a pool includes placing the person within the lap lane (6) and allowing the person to advance within the lap lane (6). A signal is transmitted from a transmitter (16) and the signal is received. In response to the received signal, a first tactile stimulus is generated which is felt by the person. This tactile stimulus indicates to the person that he/she is on course. In the event that the tactile stimulus is no longer sensed, the method may further comprise altering the course that the person is transverse within the lap lane (6). The signal from the transmitter (16a-16f) located on the bottom of the pool (2) continues to transmit a signal which in turn said signal is received once the receiver is positioned above the transmitter (16).

摘要： The present invention provides a method and apparatus for utilizing magnetoresistance devices for the measurement of weak magnetic fields. An oscillating excitation magnetic field is applied to a magnetoresistive (MR) sensing element such that the MR element is driven into one or both of two antiparallel saturation states. The amplitude of the excitation field is large enough to reverse the magnetization of the soft layer during each cycle. In one embodiment, the MR element is provided with a current, and a voltage proportional to the resistance is measured. Components of the voltage signal at multiples of the excitation frequency are then proportional to the environmental magnetic field. In one embodiment, an MR element having a resistance-versus-field transfer function that is symmetric (e.g., an anisotropic MR element) is used; while in another embodiment, an MR element having a resistance-versus-field transfer function that is asymmetric (e.g., a spin-valve MR element) is used. Various apparatus and methods for measuring the amount of time spent in one or both saturated states versus the unsaturated or transition states are described. In one embodiment, the magentic excitation field is generated using a current strip deposited onto the top of the other device layers, so that the entire device can be produced on a single chip. In one embodiment, a 'flexible' magnetoresistive structure includes a 'flexible' ferromagnetic layer having a hard-magnetization-portion layer, and a soft-magnetization-portion layer, thus providing a smooth magnetic transition when this bilayer switches. One embodiment includes s supporting data-read head structure that positions the flexible magnetoresistive (MR) sensing element to sense a magnetic field in a data storage device such as a magnetic-disk drive.

摘要： A solid state compass uses arrays of Hall effect devices for indicating direction. The Hall effect devices (H1, H2) in an array are arranged in parallel and electrically coupled in series, the outputs of this array of the Hall effect devices are amplified by difference amplifier (OP1). The difference amplifier's outputs are fed to a polarity recovery circuit (OP2, OP3) to recover its original voltage polarity for the correct sensing of the polarity of the magnetic field. The output signals from the polarity recovery circuits are then processed by the largest voltage sensing circuit (T1, T2) to sense the largest possible magnitude of the amplified signals. This signal is then stored to a buffer (L1) controlled by a logic control circuit (I1, I2, I3, I4, I5), which is also used to reset the largest voltage sensing circuit. The buffer output is used by display driver and display element (D1, LED) for indicating the sensed direction. Additional arrays of Hall effect devices can be configured to improve directional resolution.
