摘要： With an apparatus according to the invention it is possible to detect an object's velocity transverse to the direction of propagation of an interacting field. Such transverse movement is detected by applying a field that oscillates spatially in the transverse direction. The method used in the apparatus is applicable where wave energy is used to sense or detect an object by its scattering properties when using either sound waves or electro-magnetic waves. The movement can be detected according to the field properties. The field represented by the sampling pulse must feature a spatial oscillation in the directions, where the velocity components are of interest. Such a transversely oscillating field is e.g. generated by using apodization on individual transducer elements and a special focusing scheme. The apparatus uses waves of either sound or electro-magnetic radiation. The temporal characteristics are determined by the setup of the emitter (1). The spatial characteristics are determined by the transmitter array configuration (3) and the receiver array configuration (5) and the respective beam formers (2) and (6a, 6b, 6c). The transmit array consists of N elements and the receive array consists of M elements. The transmit beam former and the receive beam former are configured to obtain the spatially oscillating field. The signal received from the interacting objects (4) is processed by the velocity estimator processor (7) for calculation of the velocity vector components by estimating the shift in position as a function of time and the velocity is derived herefrom.

摘要： In order to transmit data supplied by a rotational speed sensor in the form of an alternating signal (ES) along with additional data (ZD) via a signal line (3), a sequence of electrical pulses (P) of a given duration is derived from the alternating signal. The intervals or interpulse periods of said sequence contain information on rotational speed. Additional data (ZD) is transmitted in the interpulse periods, wherein transmission of additional data (ZD; Bto to Bt7) is synchronized by the individual rotating signal sensor pulses (P). Preferably, the method is employed for active sensors (1), whereby the sensor pulses (P) and the additional data (ZD) are transmitted in the form of electric signals (Bto to Bt7). During standstill, when no sensor pulses (P) occur, transmission of additional data is triggered by auxiliary synchronization pulses (Sy2).

摘要： A remote targeting apparatus and method comprising surrounding a projectile target with a sensor array, computing projectile impact data, transmitting the data, receiving the data at a controller; and displaying information corresponding to the data. RF transmission/reception is performed, most preferably at a frequency of between approximately 902 and 928 MHz, with the controller having RF Faraday cage shielding and collision avoidance being employed to permit multiple sensor arrays to operate in a vicinity of one another. Projectile impact locations within twelve inches of the center of the projectile target are calculated to an average RMS accurancy of less than approximately fifty thousandths of an inch, directly in an orthogonal Cartesian coordinate system. Velocity is also determined via an additional sensor at a predetermined distance from the sensor array which measures a difference in time between the projectile passing the additional sensor and the sensor array. The preferred sensor array has at least two pairs of acoustical sensors, with an additional acoustical transducer orthogonal to the two pairs.

摘要： An accelerometer is fabricated by forming a proofmass (294, 295, 544) and at least one associated hinge (296, 522) in a silicon substrate (12, 112) by ion implantation and the formation of anoxide support layer (40, 42, 44) below the proofmass, subsequently integrally bonding two complementary proofmass (294, 295) and substrate structures (112) together, and then removing the oxide support layer (272) to leave the proofmass (294, 295) supported by the hinge (296) within the body of silicon material. The proofmass (300) may be electrically connected to a lead (174) extending through an etched recess (178) in one of the substrates; and the proofmass (294, 295, 300) may be electrically isolated or separated from the substrates (112) by an oxide layer (272) and by a change in conductivity type of the semiconductor material where the hinge (296) is structurally mounted to the substrates.
