摘要:
The use of an articulated transformer whose windings do not completely encircle the shaft, and with a small gap in-between being provided so that the mounting structure can be opened and the windings slipped over the shaft before being closed once again to form a tuned transformer resonating at the frequency of an electrical power oscillator connected to transmit electrical power from a first location towards a second location.

The present invention is intended to provide a ultra-precision high sensitivity displacement measuring device which has such a high resolution as to be able to make submicron measurement. According to the invention, there is provided a displacement measuring device with high resolution, comprising: an electromagnetic system (10) which forms a closed loop of magnetic blocks (17,19) and which houses primary coil bundles (11) and secondary coil bundles (13) for forming magnetic fields within said closed loop of magnetic blocks (17,19); plate springs (20) which include displacement input parts (21) and displacement output zones (24) fixed to the cores (14) having the secondary coils wound around them and which act to guide so that the displacement output zones (24) can output the displacement amplified in proportional to the displacement input to the displacement input parts (21); and a supporting mechanism (30) for supporting the displacement input parts (21) of said plate springs (20) so that the displacement may be input only in one axial direction.

A detect ion unit 10, which is disposed in opposite relation to a scale 12, includes a transmission coil 10a and a detection coil 10b. A metal film 10g formed of two opposing metal films is provided between a silicon substrate and the transmission coil 10a, one of the two metal films is connected to a drive circuit 10c, and the other is connected to the transmission coil 10a. The metal film 10g provides the capacitance C of an LC resonance circuit, so that a chip capacitor is made unnecessary. The metal film 10g may be formed of a magnetic material.
摘要:
A system for transmitting data between a rotating system and a stationary system. This system has a patch antenna affixed to the surface of a rotating body. A transmitter splits an RF signal into n identical RF signals. The n RF signals are phase shifted to have phases that are 360 divided by n degrees apart. The RF signals are then sequentially applied to the n patch antennas which broadcast the RF signals. A stationary receive antenna receives broadcast RF signals from one of the n patch antennas at a time. As a first antenna rotates out of range of the receive antenna, second antenna rotates into range. The phase shift between the RF signals broadcast between from the first and second antenna assures that data is not lost as the rotation occurs.

The system of the invention is used in measuring sports metrics at an event or venue. The system includes “n” sensors, “m” repeaters, a base station and an operations terminal. One or more sensors attach to each athlete (and/or the athletes vehicle) at the event or venue to determine a sports metric, e.g., airtime, g's, drop distance, spin, rotation. The information about the sports metric is transmitted to one or more repeaters; and that information is relayed to the base station. The operations terminal provides a user interface, and may further interface with a judging station or TV to provide the sports metric, in near real-time, to judges, viewers and others at the event or venue.
摘要:
A bi-dimensional position sensor that can be advantageously used in the turn system controlled from the steering wheel of a vehicle. The sensor includes a permanent magnet fixed to a control lever so as to move in a plane along first and second directions and to rotate about a third direction orthogonal to the preceding ones. The permanent magnet is movable with respect to an integrated device including a first group of sensor elements arranged spaced along the first direction, a second group of sensor elements arranged spaced along the second direction and a third group of sensor elements detecting the angular position of the permanent magnet. Electronics integrated with the sensor elements generate a code associated with each position which the permanent magnet may assume and generate a control signal corresponding to the desired function.

A rotary position transducer with a cosine and sine attenuating voltage wave output has the substantially linear portions segmented and pieced together from a predetermined set of conditions to form a continuously linearly varying voltage output.
摘要:
A wide-area remote telemetry system which monitors and controls remote devices by means of a information control system. The system uses a plurality of sensor interface modules which constantly monitor devices for triggering events. The sensor interface modules transmit information to at least one data collection module which gathers, process, stores and transmits information to a host system via standard external communication systems. The host module receives, records, processes, and transmits information to the network. The information may then be transmitted to customers or may be accessed by customers as desired.
