Patent GB-2449914-A (GB)
Title: Control of constant frequency, current mode, buck-boost converters
Inventor: HAIPLIK HOLGER
IPC: G05F1/62
Filed: 2007-06-07
Abstract: A controller (10) for a constant frequency current-mode buck-boost converter, the converter including an inductor (L), a first switch (SW1, S1) connected between an input terminal (Vin) of the converter and one end of the inductor (L), a diode or a switch (D1, S2), connected between the first end of the inductor and ground, a second diode or switch (D2, S3) connected between a second end of the inductor and an output terminal (Vm,t) of the converter, and a second switch (SW2, S4) coupled between the other end of the inductor and ground. A current sensor is also present for sensing current in the first switch (SW1, S1) as a measure of the inductor (L) current. The controller (10) comprises a feedback circuit for deriving a feedback signal from the output terminal (V0) and a waveform generator (31, 32) for generating buck and boost slope compensation ramps (RMP-BUCK, RMP-BOOST) used for improving stability of operation in both buck and boost operating modes of the converter. Control logic in the controller (10) generates drive signals during every clock period to repeatedly open and close the switches at individual duty cycles determined on the basis of the feedback signal, the sensed current signal and the slope compensation ramps. The buck and boost slope compensation ramps are mutually offset with respect to one another in time, for example by 50% of a clock cycle, and the control logic uses the sensed current signal only while the first switch (SW1, S1) is closed, thus avoiding the need for additional current sensing circuitry.

Title: Torque converter clutch control using learnt valve pressure offset
Inventor: DROMARD PATRICK
IPC: F16H61/14
Filed: 2008-06-27
Abstract: An automatic transmission has a torque converter clutch (TCC) for regulating the slip between an engine speed and the transmission input speed. In order to improve first time shift quality of the transmission, the TTC is controlled using a learnt valve pressure offset which is in terms of a commanded valve bleed solenoid pressure at several line pressure levels. The valve bleed solenoid pressure is measured at a moment when the engine torque starts to increase and after setting a line pressure and checking whether certain test conditions are fulfilled. A default value, which is a sample of transmissions, is overwritten by the learned value minus a calibrated value. The test conditions may include, for example, that a selector lever is in a drive position, first gear is engaged, the transmission output is zero, and a preset minimum transmission temperature is reached. First time shift quality can be improved with a short test which takes place at the end of the vehicle production line. The longer the test time, the better the first time shift quality will be.

Title: Notification of dropped audio in a teleconference call
Inventor: DIETHORN ERIC JOHN
IPC: H04M3/18
Filed: 2009-09-03
Abstract: A method is disclosed that enables a participant in a conference call to monitor, as he is speaking, whether his speech is getting through to the other participants. A teleconference bridge receives audio signals from a group of telecommunications endpoints that are involved in a conference call. The bridge generates audio signals to be transmitted, which are based on one or more of the received audio signals. During the ongoing process of minimizing the presence of acoustic echo, the bridge might exclude one or more of the received audio signals from the transmitted audio signals. When this occurs, particularly when an active talker is being excluded, the bridge transmits an indication to one or more of the endpoints as part of one of the transmitted audio signals. The indication can be audible such as a tone or a voice, visual such as a flashing light, or tactile such as vibration.
Patent GB-2463796-A (GB)
Title: Light fitting
Inventor: COLE ROBERT
IPC: A62C2/24
Filed: 2009-09-28
Abstract: A light fitting 1 has a lamp in a housing 2. The housing 2 has one or more ventilation holes 7. A sealing plate 25 overlies the ventilation holes 7 and is biased towards them by a spring 26. During normal use the plate 25 is separated from the holes 7 by a sacrificial member 24 allowing air flow through the ventilation holes 7. In case of a fire the sacrificial member 24 melts which allows the plate 25 to move towards the holes 7 under the influence of the spring 26, until it covers them. This can prevent ventilation through the holes 7 acting to prevent spread of the fire throughout a building. The sacrificial member 24 may be a eutectic alloy.

Title: A system to detect and quantify locally provided wireless services
Inventor: ARNOLD PETER
IPC: H04W16/20
Filed: 2009-10-26
Abstract: A central registering system gathers and processes information about services provided by short range wireless routers across a dispersed geographical area. The system provides intelligent maps of wireless communications, transactions and other data useful for identifying wireless service areas in locations, providing usage patterns, identifying needs for new services or surpluses, and creating views of the value of these services. This is conducted in an automated way that demonstrates transactions from uniquely identifiable wireless transmitter devices with unique identifiers, and that these have been present in the vicinity of the router. A position detection system, coordinated at a central web server registers the position and provides web based information about where the wireless transmitters have been located, usage patterns, and ascribe values to these services.
