Patent GB-956103-A (GB)
Abstract: 956,103. Capacitors. SIEMENS & HALSKE A.G. Sept. 18, 1962 [Sept. 18, 1961], No. 35434/62. Heading H1M. In a method of making a ceramic barrier layer capacitor, which involves the usual steps of applying a silver layer 2 to a surface of a ceramic plate 1 and heating the combination so that a barrier layer 4 is formed between them, a coating 5 of a metal which exhibits oxidation-preventive or reducing action at the heating temperature is applied before the heating step to the second surface of the plate. A suitable ceramic plate material is barium titanate, and the oxidation-preventive metal is preferably aluminium, though titanium or a magnesium-aluminium alloy are also suitable. After the heating process more of the metal may be sprayed or rubbed on to the surface, and a coating 3 of silver or copper is thereafter sprayed or brushed on to complete the capacitor. Leads 6 are thereafter soldered to the electrode surfaces. The effect of the oxidation-preventive layer is to prevent the formation of a barrier layer at the silver-ceramic interface and thereby increase the capacity of the capacitor.

Inventor: KIM CHUN-SUB
IPC: H03B1/04
Filed: 1996-05-09
Abstract: A play-back/recording modulator-demodulator for a high-fidelity video play-back/recording system is disclosed. The modulator has a voltage-controlled oscillator (150); a voltage-current inverter (170); and a variable bandwidth band-pass filter (110) to derive a sine wave modulated output. The play-back demodulator has the voltage-controlled oscillator (150); the band-pass filter (110); an amplitude limiter (120); a phase-sensitive detector (130); and a loop filter (140). In the record mode, the record signal modulates the square wave output of VCO (150) and the modulated signal is filtered by the filter (110) whose bandwidth is adjusted by a current control signal related to the REC input signal. The limiter (120), detector (130) and loop filter (140) are disabled during recording. During playback, VCO (150) output is isolated via switch (160).

Title: Analogue to digital converter system
Inventor: RING STEVEN RICHARD
IPC: H03M1/12
Filed: 1996-11-29
Abstract: An analogue to digital converter system includes an analogue to digital converter 14 for sampling the symbols at predetermined sample timings and a feedback loop for adjusting the sample timings. The feedback loop includes an eye opening detector 16 which includes a deviation detector for determining a deviation of a digitized symbol sample value with respect to a mean sample value. Preferably, a variance measurement calculator calculates the variance of these deviations.

Title: AC voltage compensator
Inventor: HAU KING KUEN
IPC: H02J3/18
Filed: 1997-04-15
Abstract: A voltage compensator capable of stabilizing the voltage of an AC power supply includes an isolation transformer 14 and has its input 11 connected to the AC supply. The voltage at the output 12 of the compensator is monitored by an electronic circuit to detect any deviation from a nominal value, say 220 volts AC, by predetermined limits, say plus and minus 1 percent of the nominal, and the switch pattern of a transformer network 15 connected to the primary side of the transformer 14 is altered if necessary in such a way as to keep the output voltage within the predetermined limits. The output voltage of network 15 is variable in equal steps. The finest possible control of the compensator output voltage is achieved for a minimum number of switches and transformer windings. A high power rating of the compensator can be achieved with switches of relatively lower power-handling capacities.

Title: Method of Orienting an Antenna
Inventor: EDWARDS KEITH RUSSELL
IPC: H01Q3/08
Filed: 1997-07-17
Abstract: A method of installing a fixed wireless access subscriber antenna employs an antenna for receiving signals from a radio communications base station, support means to orient the antenna in elevation and azimuth and control and analysis means to provide data relating to the signal strength received from the antenna in elevation and azimuth. The control and analysis means is connected to a subscriber transceiver electronics and employs said electronics for signal reception whereby a survey of radio signals can be conducted to enable correct orientation of a subscriber antenna with respect to a suitable base station with which communications can be conducted. The method comprises determining the receive characteristic signals of all relevant radio communications base stations in the area upon rotation and elevation of the antenna about its mount and analysing the data whereby an optimum position and orientation for the subscriber antenna can be determined. By configuring the antenna mount prior to attachment on the structure, then the time required to deploy fixed wireless access subscriber equipment is much reduced.

IPC: A61B10/02
Filed: 1999-03-19
Abstract: A bone marrow biopsy needle assembly comprises a cannula 3 having at least one recess 11, 12 along its length.

Title: Portable radio information terminal and data transmitting/receiving system
Inventor: KATSUKI MASAHIRO
IPC: H04L12/28
Filed: 1999-04-23
Abstract: In a portable radio information terminal 7, if both the present level of the battery capacity and the level of received signal strength are above respective thresholds at which data communication is possible, the portable terminal 7 sends a data transmission/reception possible or enabling signal via a base station 6 to a supervising servers in an information network centre 1. If the battery level is below the data communication threshold, the terminal 7 sends a data transmission/reception impossible or disabling signal to the server 5. The terminal 7 also sends the impossible/disabling signal if the received signal strength is below the data communication threshold. A display (19. Fig.2) on the terminal may indicate whether data communication is possible or impossible. Data is not sent from the centre 1 to the portable terminal 7 unless the server 5 has received the data transmission/ reception possible signal from terminal 7. This avoids having to re-transmit data from the centre 1 in circumstances where the terminal 7 would initially not be able to receive it. The terminal 7 may send a specified time signal when data communication is to be made within a specified time, checking of battery level and received signal strength, and the resultant sending of the data transmission/reception possible signal or impossible signal, then being done when a specified time acceptance signal is received by terminal 7 from the centre 1 or when the specified time signal has been sent from the terminal 7 for a certain number of times without a specified time acceptance signal being received from the centre 1 (Figs.8-10).

Title: Configuring grade of service for mobile based on historical patterns of movement or environmental factors
Inventor: ROBINSON WILLIAM NEIL
IPC: H04W28/16
Filed: 1999-10-27
Abstract: Method and system for utilising resources of a mobile telecommunications network comprising monitoring historical 30 or environmental 39, 40, 41 data associated with a mobile terminal 38, its users or environment and at the time service is required, configuring the grade of service in accordance with said monitored data. The historical data may be historical patterns of movement of the user (figure 1) and the environmental data may relate to events that may possibly affect user's movement, e.g. traffic 39, weather 40 , public holidays 41, data relating to population movement. Real time data may also be used. The grade of service available to a mobile 38 user will vary depending on the cell being used, the physical environment, base station efficiency etc. and thus the grade of service offered when a user first registers for service may not be available or appropriate when the user moves into other cells. The invention aims to provide a more appropriate grade of service by taking into account the mobile's set patterns of movement or other factors that may affect movement.
