Patent GB-2328813-A (GB)
Title: RF zero IF direct converter system
Inventor: MANKU TAJINDER
IPC: H03D7/00
Filed: 1997-08-28
Abstract: In a RF direct down-converter system, the RF signal is split into two arms 11,12 with each arm having a mixer M1,M2. Each mixer has two inputs namely a phase modulated local oscillator signal and the RF information signal. The phase modulated local oscillator signal between each arm differs by a 90 degrees phase shift providing phase quadrature signals to the mixers M1,M2. The output of the mixers is subtracted and the output of the subtractor is mixed with the phase modulation signal. A low pass filter then removes the unwanted signals. The RF carrier signal contains digital and/or analogue information. The system may be used in cellular communications.

Title: Cable communication system and method for management
Inventor: CORRIGAN RICHARD J
IPC: H04N7/173
Filed: 1997-03-13
Abstract: A cable communication system (100) where a control unit (110) sends operation parameter to subscriber units (130) and the subscriber units (130) respond by modifying the method of communication. Also, the subscriber units (130) send messages which includes information on the subscriber unit (130) and the capabilities of the subscriber unit (130). Furthermore, the control unit (110) efficiently manages the system (100) by monitoring the capabilities and instructing the subscriber units (130) on how to communicate on the system (100). Such management allows for the migration of subscriber units (170) from one service area (140) to another (190) without the disruption of service. In addition, initialization of subscriber units (130) may be accomplished over the cable and does not require an operator at the subscriber location.
Patent GB-2320788-A (GB)
Title: Low tyre warning system
Inventor: RHODE DOUGLAS SCOTT
IPC: B60C23/06
Filed: 1997-12-22
Abstract: A system and method that monitors four wheel sensors of an automotive vehicle to determined changes in the effective rolling radii of any wheel and a low pressure tyre condition. Certain vehicle operating conditions, such as excessive or very low speeds, braking, and turns, are determined from the sensor outputs and are used to prevent erroneous detection of changes in effective rolling radii. Data from the sensors that is determined to be acceptable is accumulated over time as displacement values for each wheel. When the displacement values exceed a predetermined value, a metric function is used to compare differences detected in accumulated displacement values for the front pair of wheels and for the rear pair of wheels. If the difference between compared pairs of wheels is excessive, as compared with a predetermined baseline metric value, a low tyre condition is detected. Further accumulation of instances where the metric indicates a detected condition, provides confidence that the condition actually exists and a warning is provided to the vehicle operator. Resetting of the system and the baseline metric is performed when the low tyre condition is corrected or when the tyres are checked and properly inflated.

Title: Circuit arrangement for a three-phase alternator for a motor vehicle
Inventor: BLUMEL ROLAND
IPC: H02K3/28
Filed: 1998-07-29
Abstract: The alternator has two half windings 1, 2 which are wound in the same sense and have the same connections (both star, or delta, or zigzag) and are connected to respective rectifiers 15, 16, so that the windings 1, 2 are effectively in parallel, and each output 3, 4, 5 of winding 1 is connected by two switching devices 12, 14 or 10, 13 or 9, 11 to two outputs 7, 8 or 6, 8 or 6, 7 respectively of the other winding 2 so that when the switching devices are turned on phases of winding 1 are connected in series with phases of the winding 2. The switches 9-14 may be turned on when the vehicle engine speed is below a specific speed. By turning on one or some, but not all, of the switches 9-14 various intermediate configurations with some phases of windings 1,2 in series and other(s) in parallel may be obtained. By using these intermediate configurations, a gradual transition may be effected between full parallel connection at high speeds and full series connection at low speeds. The alternator may alternatively be operated permanently at one of the intermediate configurations, with no changeover between configurations. In alternative arrangements, individual switches 9-14 are replaced by diodes, so that one or more parts of the windings 1, 2 are permanently in series, or all of the switches are replaced by diodes so that all of parts of windings 1, 2 are permanently in series. The switches 9-14 may be thyristors or MOSFETs. Alternatively, the switches 9-14 are bidirectional and the bridge rectifiers 15, 16 are replaced by MOSFETs.
