Patent EP-0475050-A2 (EP)
Inventor: BREGMAN MARK F
IPC: G01R31/26
Filed: 1991-07-29
Abstract: A system for testing chips uses a patterned tape having a patterned array of cantilevered contact leads. The tape serves as an interface between the chip under test and a testing unit by providing conductive leads from the I/O terminals on the chip to an off-chip measuring system. The leads on the array may have balls, tips or other shapes on the end to provide contact with the terminals and compensate for height differences. The tape is a single frame or has a series of arrays each positioned around an opening where the chip will be located when a particular pattern is positioned over that chip for test. The pattern on the tape may be the same array or a different array. The tape is indexed to a new pattern when the old one is damaged or no longer needed. Alignment with the chip is by optical sensing and physical pin movement. The tape may have a flap protruding into an aperture and deflectable to provide for planar contact of the leads to the device under test.

Abstract: A method and apparatus for combining NMR response data of a sample from a plurality of closely spaced RF receiver coils of an NMR phased array in the time domain to form a composite NMR image wherein each of the RF receiver coils receives a different respective one of a plurality of NMR response signals, each of which is evoked from a portion of the sample within a field of view of a respective one of the receiver coils. The response signals are conditioned to develop a plurality of data point signals corresponding to the magnitude of each of the respective response signals from each of the receiver coils at successive time intervals. The data point signals are convolved by a time domain representation of a field map of the respective one of the receiver coils generating the corresponding one of the response signals. The convolved signals are combined on a time domain point-by-point basis to produce a time domain representation of the composite NMR image of the sample.

Abstract: A microcellular mobile radio communication system has a central base station (20) and a plurality of radio base stations (2-5) interconnected by a shared optical fiber transmission line (11-12). In the central and radio base stations, electrical radio signals are frequency-converted to frequencies assigned to the radio base stations and then converted into optical signals. In each radio base station, the frequency of the radio signal extracted from the received combined signal is frequency-converted to a frequency to be transmitted from its antenna, with the other signals filtered out. The central base station (20) demodulates (241-244) the received combined signal from the radio base stations into signals for the exchange office (30). The radio signals in different frequency bands assigned to each radio base station can simultaneously be transmitted through the shared optical fiber transmission lines between the radio and central base stations.

Abstract: A method for compressing a digital input signal to provide a compressed output signal in which pre-echo, a common defect of data compressors, is avoided. The digital input signal is divided in time into frames, and into at least one block of data in each frame. The frames include a past frame preceding a present frame. Block floating is applied to the data in the block in each frame. Quantizing bits are adaptively allocated to the data in the block in the present frame in response to the block in the past frame. Finally, the resulting quantized data is added to the compressed output signal. 
     In a first variation, a signal energy or an allowable noise level is determined for the block in each frame. A word length is determined for the block in each frame in response to the determined signal energy or allowable noise level of the block. The quantizing bits are allocated to the data in the block in the present frame in response to the word length for the block in the past frame. 
     In a second variation, a signal energy in the block in each frame is determined, and quantizing bits are adaptively allocated to the data in the block in the present frame in response to an interpolation between the signal energy for the block in the present frame and for the block in the past frame.

Abstract: The disclosure relates to hydrocyclone separators for separating liquids of different densities such as oil and water. The separator has an axially elongated chamber (11), a feed inlet (21) for introducing liquid into the chamber at high velocity in a tangential direction so that the liquid rotates about the axis of the chamber, an overflow outlet (23) for removing the less dense liquid from the chamber, and an underflow outlet (14) for removing the more dense liquid from the chamber. A turbulence shield (18) is positioned between the feed inlet (21) and the axially disposed outlet (23) for isolating the overflow outlet from the effects of turbulence produced by the liquid entering the chamber. In some disclosed embodiments, the chamber is rotated about its axis to produce a centrifugal force which enhances separation of the liquids, and tapered impeller vanes which increase in radial extent away from the feed inlet gradually accelerate rotation of the liquids as they move away from the inlet.

Abstract: A digital communications system with fast facility protection is disclosed. The system includes at least one digital cross-connect (2) which is in bidirectional communication with east and west routes (EAST, WEST) of the network via east and west transmit ports (E O , W O ) and east and west receive ports (E I , W I ). The cross-connect (2) broadcasts a facility over both the east and west routes, and receives the return facility over one of the routes. The cross-connect (2) monitors the error status of the received facility (E I ) for hard error conditions and excessive error rates, by way of a distributed processor (16) in communication with the port (E I ). In the event of an error, the cross-connect blind switches the facility to the inactive port (W I ) by way of a receive-end switch, according to a first embodiment. According to another embodiment, a head-end switch is performed, thus allowing for improved flexibility for port assignment in the cross-connect (2).

Abstract: A fabrication method of a compound semiconductor integrated circuit device, in which the backgating effect and the sidegating effect are restricted thereby to improve its device-isolation characteristics and productivity without using a low-temperature buffer layer. After a crystal-defective layer is formed on a main surface of a compound semiconductor substrate by an ion-implantation technique, an active layer is formed thereon and then a compound semiconductor buffer layer is formed on the buffer layer. Next, a recess for isolation purpose is selectively formed to make device regions through the active layer with extending to the buffer layer by an etching technique. Subsequently, a gate electrode and source and drain electrodes are formed on the active layer and a backgate electrode is formed on the reverse side of the substrate.

The error indication is checked to determine whether it meets a certain criterion and, if so, the element approximation is used as the page definition language representation. Otherwise, one or more further element approximations are developed until an element approximation is obtained that results in an error indication which meets the certain criterion.

Abstract: In video/audio compression, a video signal is separated into luminance and a color difference. The color difference is partially subsampled. An interframe difference is compression-coded by an encoding unit. At that time, particular subsampling information corresponding to a designated reproducing rate is extracted from subsampling information. The particular subsampling information is inserted into compressed video data. On the other hand, in video/audio reproduction, the color difference of the video, which has partially been subsampled, are interpolated by a decoding unit with reference to the subsampling information inserted into the compressed video data.

Abstract: A signal detecting device for detecting a pilot signal component from a modulated digital signal which contains information data and the pilot signal component, comprises an A/D converter (109) for performing analog-to-digital conversion of the modulated digital signal and a restoring circuit (110,114) for restoring the information data by using an output of the A/D converter.

In addition, since an A/D converter identical to the restoring circuit can be used as an A/D converter for detecting the pilot signal, it is possible to realize the detection of the pilot signal by means of a simple circuit construction.
