Abstract: A specimen to be tested for resistance to abrasion is optically scanned prior to abrasion to produce a first array of pixels. The specimen then is abraded under controlled conditions and scanned again after abrasion to produce a second array of pixels. The sections of the two arrays which relate to the specimen are registered to each other. Corresponding pixels for the specimen in each array are compared to produce plurality of values indicating the difference between the pixels. The difference values are used to quantify the abrasion in various defined regions of the specimen. The quantifying employs the difference values to determine an average magnitude, a mean square energy, and an average voltage of the abrasion. A contour map of the specimen is displayed to graphically show the degree of abrasion in the regions.

Abstract: An active noise control system (26) includes a configuration of signal generators (200-204) and corresponding paired adaptive filters (206-210). Each signal generator (200-204) produces a generator output signal containing one or more sinusoidal signal components, with each signal component having a frequency corresponding to a respective one of the noise frequency components. Separate signal generators (200-204) are used to produce those sinusoidal components having frequencies corresponding to noise components that are adjacent with respect to their frequencies. Each adaptive filter (206-210) operates on the generator output signal produced by its corresponding paired signal generator (200-204) in accordance with its filtering characteristics to provide a respective filtered output signal. The filtered output signals from each adaptive filter (206-210) are summed to obtain an output cancelling signal, which drives an actuator (28,32,36) to produce output cancelling waves that are superimposed on the undesirable noise. An error sensor (30,34,38) measures the level of residual noise resulting from the superposition of the cancelling waves on the undesirable noise, and provides an error signal for adapting the characteristics of the adaptive filters (206-210) so as to minimize the level of residual noise.

Abstract: A high pressure discharge lamp includes a resistive fuse (30) for overcurrent protection of its associated ballast, which fuse is connected electrically in series with the discharge vessel (1) of the lamp and continuously dissipates power during lamp operation. The resistive fuse is heated by passage of the operating current through the discharge vessel (1) during lamp operation to a temperature substantially controlled by the operating current. In response to an increase in the operating current to a predetermined overcurrent, the resistive fuse (30) reaches a temperature such that it breaks and disconnects the discharge vessel (1) from its source of electric potential within a predetermined time period. The fuse (30) passes short-term high starting currents and does not disconnect the discharge vessel(1) during each lamp start-up at least until the operating current reaches the predetermined over-current during lamp life.

Abstract: Channel selecting operation of a tuner is controlled by a VTR microprocessor. A broadcasting station code detected by a broadcasting station code detector 4 from an output video signal SV from the tuner is supplied to the VTR microprocessor. To the VTR microprocessor, there are connected a first memory which stores, in advance, data representing the corresponding relationship between broadcasting station codes and VCR+ guide channels, and a second memory which stores data representing the corresponding relationship between channels selectable by the tuner and the VCR+ guide channels. When an automatic setting key on a remote control commander or a key input circuit is pressed, the VTR microprocessor controls the tuner to select channels successively, reads VCR+ guide channels corresponding to the broadcasting station codes detected by the broadcasting station code detector from the first memory, and writes the VCR+ guide channels in the second memory in relation to the channels selected by the tuner.

Abstract: Diversity for direct sequence spread spectrum wireless communication systems is provided by a transmitting technique for communicating a first signal comprising one or more segments to a receiver via a plurality of M antennas (T₁, T₁). The first signal includes one or more signal segments. The technique cmprises forming M copies of the first signal; for a segment of a signal copy, weighting (by 15) each of two or more sub-segments of the segment with a distinct signal (from 17), wherein a sequence of the distinct weighting signals for the segment is distinct from sequences of signals weighting the same segment of one or more other signal copies; and for each of M weighted signal copies U₁(n)..U m (n), transmitting a signal to the receiver using a distinct antenna (T₁, T₁), the transmitted signal being based on the weighted signal copy. Illustratively, the first signal is a spread spectrum signal (by 10,12). Moreover, the process of weighting comprises applying a phase shift to a sub-segment. The invention further provides a receiving technique which comprises, for a copy of a received signal, despreading a segment of the received signal, demodulating a plurality of sub-segments of the despread signal segment, wherein each sub-segment is demodulated with use of one or more estimated communication channel characteristics corresponding to the sub-segment, and forming a summation signal reflecting a summation of a plurality of demodulated sub-segments. The receiving technique further comprises forming a signal reflecting a signal segment value, the formed signal based on one or more summation signals. The step of demodulating may precede the step of despreading in some embodiments.

Abstract: A magnetic tape (21) has three evenly spaced-apart longitudinally-extending servo track areas (40-42). Four equal-sized longitudinally-extending data track areas (45-48) are disposed between said servo track areas (40-42) and between longitudinal edges of the tape (21) and one of said data track areas (45-48). All servo track areas (40-42) are simultaneously sensed for producing one head positioning signal (100). Data tracks are arranged into four groups of tracks (45-48), one-half of the data tracks in each group are concurrently accessed. The data tracks on the tape are arranged in clusters. Each cluster has one track from each of the groups of tracks. Two laterally-adjacent track clusters constitute four data track wraps for serpentine scanning of data tracks. The concurrent track accessing respectively occurs in first and second halves of a data track wrap. Each servo area indicates two lateral positions of the tape to the head (27). The lateral spacing between the lateral positions is equal to about a data track width. This arrangement makes the servo areas field writable.

Abstract: A combined interferometer and refractometer includes two interferometers each of which uses a light beam produced from a common source which are split into measuring component beams and reference component beams. The measuring component beams are directed along parallel paths to an object and are reflected back from reflecting surfaces on the object which is so positioned as to produce a fixed path length difference between the beams. The reflected beams are re-combined with the reference component beams to produce output beams which pass to a detector system which derives an output signal from each. Changes in refractive index are determined from any difference in the two output signals, and the distance moved by the object is determined from any change in either one of the output signals or by summing them and dividing by two. Methods are described whereby the measurements of refractive index or of distance can be made absolute.
