Patent EP-0238041-A3 (EP)
Title: Phase locked loop circuit
IPC: H03L7/091
Filed: 1987-03-17
Abstract: The circuit uses a reference signal ( 
r1) and 
a response control signal ( 
c1) with a preset transition time, and 
comprises a voltage-controlled oscillator (58) to produce a signal ( 
v1) 
variable in phase, a phase detecting 
circuit (10, 12, 14) delivering up (S₃) 
down (54) pulses to a first (16) and a second (32) charge pump 
circuit. Each of the charge pump circuits has three states. A first 
first state to advance the phase of the variable-phase signal, a 
second state to retard the phase of the variable-phase signal, 
and a third state to maintain the phase of the 
variable-phase signal. The circuit further comprises 
a response control circuit (26, 28) responsive to the 
response control signal for maintaining the second charge pump 
circuit in the third state at 
a time subsequent to a phase difference detect period, thereby modifying 
the rate at which the voltage controlled oscillator responds to the 
up down pulses.

Title: Vehicle information device
IPC: G07C5/10
Filed: 1987-08-27
Abstract: A vehicle information apparatus for recording, computation and display of data ascertainable from the driving performance of a motor vehicle. The apparatus includes a transmitter module for providing data concerning a trip, a central unit with internal program and data memories and a display device. The vehicle information apparatus is coupled with the operating mechanism of a radio cassette set for playback of data information stored on an audio data carrier. The transmitted data are separated in a signal input and output stage of the apparatus, stored and displayed. The audio data carrier is repeatedly loaded with topical information and serves particularly for the distribution of instructions prior to the start of a driver's shift in a taxi or transportation vehicle fleet.
Patent EP-0239408-A3 (EP)
IPC: G01B11/30
Filed: 1987-03-26
Abstract: A periodic localized excitation is generated at the surface of 
the sample (22) with an intensity modulated pump laser beam (34). A 
probe laser beam (52) is directed to the surface of the sample (22) 
and changes in the probe beam (52) which are in phase with the 
modulated pump frequency are detected by a photodetector (62) 
connected to a processor (64) also coupled to the modulator (36) of 
the pump beam (34). Periodic changes in the optical reflectivity of 
the surface of the sample (22) induced by the pump beam (34) are 
detected by measuring the corresponding modulations in the reflected 
power of the probe beam (52). Time dependence of the probe beam 
modulated reflectance signal is monitored. An evaluation of defect 
surface states is then made by investigating the time dependence of 
the magnitude and/or phase of this probe beam modulated reflectance 
signal.

Title: Microcomputer capable of quickly processing a branch instruction code
IPC: G06F9/38
Filed: 1989-11-27
Abstract: In a microcomputer for use in combination with a 
memory which memorizes a sequence of instruction codes 
including branch instruction codes and ordinary 
instruction codes, each instruction is prefetched from 
the memory to a bus controller and monitored by a branch 
destination address calculator to detect whether or not 
each instruction code specifies the branch instruction 
code to calculate a branch destination address indicated 
by the branch destination address. Such calculation of 
the branch destination address is carried out before the 
branch instruction code is fed to an execution unit 
through an instruction code memory and executed by the 
execution unit independently of prefetch operation in 
the bus controller. The branch destination address 
calculator comprises a branch instruction detection 
circuit for detecting a branch instruction code and an 
address calculation circuit for calculating the branch 
destination address when the branch instruction code by 
the branch instruction detection circuit.

Patent EP-0336502-A3 (EP)
IPC: H03M3/02
Filed: 1989-03-30
Abstract: In a device for and a method of encoding a first signal 
(f₀), for example a speech parameter such as the pitch, as a function 
of time, to form a second signal, a third signal (k) is derived 
from the first signal, which third signal is a measure of the curvature 
of the first signal as a function of time. The extrema (such as k(t₁) 
in Fig. 1b) in this third signal are determined and the second signal is 
generated in the form of a sequence of information blocks, 
of which one information block contains time 
information corresponding to the instant at which an extremum 
occurs in the third signal.  
     A special encoding method is described, which is 
substantially immune to noise in the first signal.
Patent EP-0344882-A3 (EP)
Title: Low vibration resonant scanning unit for miniature optical display apparatus
IPC: G06K7/10
Filed: 1989-02-24
Abstract: A resonant scanning unit utilizes a "tuning fork" design with a mirror (30) mounted on one arm of the tuning fork and a counterbalance mass (40) mounted on the other arm. A voice coil electromagnetic motor (44, 46) mounted between the arms causes the arms to move in opposite directions. Light generated by a line of LEDs is reflected from the oscillating mirror (30) to generate a raster display. Reaction forces generated by the motions of the mirror (30) and counterbalance mass (40) cancel at the device base (21), reducing vibration. In addition, the inventive structure allows placement of the mirror pivot point away from the center of the mirror which allows display devices constructed with the structure to be reduced in size.

IPC: D06M11/82
Filed: 1989-03-17
Abstract: A flame retardant fibre material is produced by immersing 
vegetable fibre into a first inorganic compound solution 
and then into a second inorganic compound solution. Both 
solutions enter into the gaps between the vegetable 
fibres and contact each other to produce an insoluble and 
incombustible inorganic compound which is deposited on 
the fibres in the gaps therebetween. The thus deposited 
inorganic compound imparts flame retardant properties to 
the vegetable fibre.
