Title: Method and circuit arrangement for assuring the bit synchronization of a data block in a receiver
IPC: H04L7/033
Filed: 1987-08-05
Abstract: For synchronizing a data block in a receiver, there are transmitted consecutively and prior to the data block: a first bit sequence of alternating "0" and "1" levels for determining the bit clock and a second bit sequence for determining the block synchronization by correlation. In known methods of determining the bit clock, the phase range of the individual bits of the received digital signal is divided into sub-intervals and the phase position of the bit clock is determined on account of the number of edges in these sub-intervals. In order to avoid fading and phase jitter having a detrimental effect on the bit synchronism, more specifically when transmitting through radio transmission links, N-phase-shifted clocks having the same clock frequency are generated in the receiver by means of which the first bit sequence is sampled. The clock for which the number of sample-value changes of the first bit sequence is established as having a predeterminable minimum value during a predeterminable time-interval is utilized as the phase synchronous bit clock.

Patent EP-0311768-A3 (EP)
IPC: G01N33/487
Filed: 1988-08-12
Abstract: There is provided a novel method of testing for the 
presence of an analyte in a fluid suspected of containing 
the same. In this method, in the presence of the analyte, 
a substance capable of modifying certain characteristics 
of the substrate is bound to the substrate and the change

     While the method may be modified for carrying out 
quantitative differential analyses, it eliminates the need 
for washing analyte from the substrate which is 
characteristic of prior art methods.

Title: Mri qd rf coil having diode switched detuning circuit producing reduced artifact
IPC: H01F7/20
Filed: 1988-08-20
Abstract: A detuning/decoupling arrangement for a Magnetic Resonance Imaging (MRI) system quadrature RF coil arrangement (of the typing using the nuclear magnetic resonance, or NMR, phenomenon) uses switching diodes to selectively connect and disconnect portions of a segmented RF coil in response to a DC control signal. The DC control signal selectively forward biases and reverse biases the switching diodes. The DC control current flows through the RF coil itself, through the diodes, and then through the center conductor of a semi-rigid transmission line disposed in proximity to the RF coil. Because the DC current flowing through the transmission line is equal and opposite to the DC current flowing through the RF coil, the net magnetic field generated by the DC current flow is approximately zero -- eliminating artifacts in the MRI image that would otherwise be generated due to continuous DC current flowing whenever the coil is being used to transmit or receive RF.

Patent EP-0279678-A3 (EP)
IPC: H03H9/42
Filed: 1988-02-18
Abstract: A surface wave acoustic delay line is formed 
of a set of electrode assemblies [24,26] disposed on 
the surface of a block of crystalline material [12] 
propagative of a surface acoustic wave. In each of 
the assemblies, the electrodes are arranged in an 
interdigitated pattern. Reflected waves are cancelled 
by the construction of an additional electrode in each 
of an electrode assembly, the additional electrode 
extending only one-half the distance of the other 
electrodes and being spaced from an adjacent electrode 
by one-quarter wavelength. This introduces a 180° 
phase shift between portions of reflected waves which 
then cancel to remove the reflection. Also, in the 
case of closely spaced electrode assemblies, 
additional electrodes, equal in shape and size to the 
electrodes of the assemblies, are introduced between 
the assemblies in the form of a grid which propagates 
surface waves without reflection.
