Title: Telecommunications service network
Inventor: WILSON JEFFREY
IPC: H04M3/428
Filed: 1991-07-18
Abstract: In a public telecommunications system, the line 11, 12 between a switching exchange 10 and each telephone terminal A, B, C is divided by a switching interface including a number of interface switches a, b, c. The interface switches a, b, c are connected to a service bank 15 via a multiplexer/distributor 16. A switch device 13 within each interface switch a, b, c can be selectively set to provide connection between the respective terminal A, B, C and either the exchange 10 or the service bank 15. Thus, for example by dialling a specific code, it is possible to obtain direct connection to the service bank 15 without using up the switching capacity of the exchange 10. Call breakthrough from another (non-service) terminal can be provided to interrupt connection to the service bank 15, and in another arrangement, the exchange is capable of distinguishing between service and non-service lines to enable such call breakthrough only during connection to a service line. <IMAGE>

Title: Television startup current regulation using thermistor of degaussing system
Inventor: WU CHUN HSING
IPC: H02M1/00
Filed: 1992-06-24
Abstract: A television receiver has a switched mode power supply controller 60 which produces pulses in a power transformer X1. To power the controller during startup, before the internal power supply has started, a storage capacitor C5 is coupled through a current limiting resistance R2, V1 to a rectified voltage from the AC mains 22 so as to charge the storage capacitor during first polarity phases of the AC mains. The current limiting resistance includes a positive temperature coefficient (PTC) element V1 which increases its impedance as it heats, to reduce power dissipation after initial connection of the television receiver to AC mains. In addition, a diode D7 is coupled in a current path to the storage capacitor to charge the capacitor to the same polarity as during opposite polarity phases of the AC mains. The two paths for charging the capacitor allow a relatively smaller value for the current limiting resistance (R2, V1), which remains coupled to the storage capacitor C5, and provides sufficient power to the controller 60 without undue power dissipation over a wide range of power mains voltages. The PTC element V1 is thermally coupled with the PTC element V2 which is in series with the degaussing coil L3. <IMAGE>

Title: Oxygen measuring system utilising solid electrolyte sensor and pump
Inventor: BENAMMAR MOHIEDDINE BENAMOR
IPC: G01N27/419
Filed: 1992-08-26
Abstract: The system comprises an enclosed volume bounded by a solid electrolyte oxygen pump and a solid electrolyte oxygen sensor, each of which has one electrode in the enclosed volume and the other in the sample gas. A heater maintains the temperature of the sensor at a desired value. The sensor EMF is compared with a separately generated periodically oscillating voltage (SGPOV) and the difference between them is maintained constant by a feedback loop controlling the current to the pump. The resulting periodically oscillating pump current is analysed to determine the oxygen partial pressure and/or concentration of the sample gas. The volume may be closed or a diffusion path comprising one or more small holes may be provided. The system provides a measurement of oxygen partial pressure which is independent of the degree of leakage between the enclosed volume and the sample gas: it can also quantify the degree of leakage. <IMAGE>

Title: Rectifier circuit not using a clock signal
Inventor: KIMURA KATSUJI
IPC: H03D1/18
Filed: 1992-10-05
Abstract: In a first arrangement, an AC input is applied to a differential amplifier 10 connected to a constant current source CS1, the output of amplifier 10 is applied to an amplifier 11 which provides a rectified output and incorporates two differential amplifier transistor pairs M3, M4 and M5, M6 gain controlled by signals 104, 105 which are respectively at DC levels VH, VL when the AC input is positive and VL, VH when the AC input is negative. The signals 104, 105 are changed over by switches S91, S92 controlled by a polarity judgement circuit 8. In a second arrangement, (Figure 4), a first amplifier (28) differentially amplifies the AC input and a first DC signal, (302) a second amplifier (29) differentially amplifies the AC input and a second DC signal (303), and the outputs of amplifiers (28), (29) are connected in antiphase to provide a rectified output. The signals (302), (303) are changed over between (E1), (E2) and (E2), (E1) respectively by switches (S71), (S72) controlled by a comparator (A71) which judges the polarity of the AC input relative to a DC bias (E0) rather than relative to zero. The first and second arrangements may be modified, (Figures 2A, 4A), to give half wave instead of full wave rectification. In a third arrangement, (Figure 3), the AC input is applied to a first 10 amplifier (18) incorporating first and second differential amplifier transistor pairs and first and second constant current sources. The output of amplifier (18) is supplied to a differential output current generating circuit (19) incorporating three current mirror circuits and yielding an output current having a constant DC component and a component varying with the AC input. The DC component is removed in an amplifier (20) which gives a full wave rectified output. Differential amplifiers of the second and third arrangement may each comprise a pair of transistors which have different capacity values. The arrangement may be implemented as an integrated circuit using MOS or bipolar transistors or both. <IMAGE>

Title: Counting people entering and leaving a zone
Inventor: FITTER ANDREW
IPC: G07C9/00
Filed: 1994-03-30
Abstract: A counting device can be used to switch the lighting on when a person enters the room and switches the lighting off when the room is empty. The device has a passive infra-red sensor which emits a pulse whose polarity is dependent on the direction of movement of a person into or out of the room. The pulse is passed to a counter which is incremented or decremented accordingly. The value of the count is representative of the number of persons present in the room. When the count indicates the room is empty the lighting is extinguished. The sensor may comprise two pyroelectric detectors A and B wired in opposed parallel manner and having spaced fields of view through a slit X. Movement of a person in direction Z produces a positive pulse followed by a negative pulse, whiist movement in the opposite direction produces a negative then a positive pulse. Further circuitry detects the polarity of the first pulse of the pair. <IMAGE>
