Abstract: ABSTRACT         A test jig for measuring the static characteristics of 3-terminal microwave active components has mechanical supports for two dielectric substrates. Two terminals of the components under test are separately connected to electrical circuits constructed on the dielectric substrates. The test jig can be adapted to the size and shape of the casing of the component under test,  and allows it to be submitted to thermal tests without mechanical stresses due to expansion. The  electrical  circuits  constructed  on  the  dielectric substrates ensure circuit stability thus avoiding spurious oscillations during static characteristic measurements.

Abstract: Abstract A system and method  for generating  2n test patterns is disclosed.  The system utilizes a linear feedback shift register (LFSR) to generate a sequence of 2n-1 test patterns.   In addition, the system includes  apparatus  external  to the  shift register which generates a 2nth test pattern.   A switching circuit is employed to insert the 2nth test pattern into the sequence of test patterns. Therefore, a 2n test pattern sequence is generated. The test pattern sequence produced is pseudo-random in nature.   The system further includes an output for providing a test pattern; such output could be used for the testing of a VLSI sub-system such as ROM.  A method utilizing the techniques embodied in the system is also disclosed.

Abstract: A single international standard integrated services digital network (ISDN), basic rate interface (BRI) is arranged so that either a data terminal and two voice terminals, three voice terminals, or four voice terminals can be operated simultaneously through the interface. Code converters, associated with the voice terminals and with a central office switch, convert eight-bit voice sample code from either the voice terminals or the central office switch to four-bit voice sample code in the interface to enable the bit streams of two voice terminals to be merged for transmission through a single B-channel at the interface. When two voice terminals are operated simultaneously through one B-channel, each of those terminals positions four-bit coded voice samples in a different sub B-channel of the B-channel and stuffs four bits in the other sub B-channel. Four-bit coded voice samples from the sub B-channels are converted to voice samples in the voice terminals and to eight-bit codes voice samples in the central office switch.

Title: High signal to noise ratio amplitude detector
Inventor: HERLEIKSON EARL C
IPC: H03D1/10
Filed: 1989-09-07
Granted: 1991-07-30
Abstract: High Signal To Noise Ratio Amplitude Detector Abstract A low noise floor amplitude detector circuit utilizes a pair of semiconductor diodes connected between a radio frequency signal source and a terminating device that biases the diode at a conduction angle selected for maximum signal to noise ratio in the detector circuit.          Optimum bias conditions and a low signal to noise ratio is achieved by using a conduction angle at each diode of 1.656 radians (approximately 67 degrees). This also results in matching of the radio frequency load impedance of the amplitude detector to the radio frequency impedance of a signal source.

Title: Optical fibre monitoring
Inventor: LEWIS JOHN D

Filed: 1989-09-27
Granted: 1992-08-18
Abstract: ABSTRACT       A "clip-on" device for detecting whether or not an optical fibre is carrying a light signal includes bending means for controllably causing a portion of a fibre to be subjected to a gradually increasing amount of deformation and a first detector for detecting light escaping from the bent fibre.  A second detector detects when the fibre has been subjected to a predetermined maximum amount of deformation.  If light is detected by the first detector a signal is sent to a control unit which stops the bending means from further increasing the amount of fibre deformation and gives a first output indication.  If the second detector detects that fibre deformation has reached the predetermined maximum amount and no light signal has been received, a signal is sent to the control unit which stops the bending means from further increasing the amount of fibre deformation and gives a second output indication.  Preferably, the bending means is in the form of a frustom of a cone which has in its curved surface a helically extending groove and which can be helically driven about its axis.          The leading end of an optical fibre is initially disposed in the groove at the larger end of the mandrel and the mandrel is rotatably driven about its axis.
