Title: Power converter comprising multi-functional current sense pin
Inventor: YOUNG GEORGE
IPC: H02M3/335
Filed: 2012-01-24
Abstract: A power converter controller device is formed as a packaged integrated circuit. The device includes a means for generating a first control signal to control the on time of a regulation switching transistor (control 1 figure 1, 3). A first package pin connects the first control signal ((control 1 figure 1) to the regulation switching transistor in the power converter circuitry. A sense resistor (Rsense, figure 1) is placed in a current path in the power converter circuitry, the current path being conducting when the regulation switching transistor is on and non-conducting otherwise. A second package pin (sense/control 2) is connected to the sense resistor and coupled to circuitry integrated within the controller device to sense a voltage across the sense resistor when the regulation switching transistor is on. The device also includes a means for generating a second control signal (control 2, figure 1) and means for coupling the second control signal to the second package pin when the regulation switching transistor is off. Thus the device has a sensing capability when the switching transistor is on and a control capability when it is off. The control capability is particularly suited to control of a synchronous rectifier within the power converter (see figure 3). Embodiments are also shown in figures 4 and 5 for magnetically and optically coupled synchronously rectified isolated converters.

Title: Curved heated ion transfer optics
Inventor: ZANON STEPHEN
IPC: H01J49/06
Filed: 2012-07-11
Abstract: An ion optics assembly 315 is formed by four quarter-circular profile elements, all of which are attached and aligned to the same reference plate (465, Fig 4). The four elements form a quarter-circular quadrupole ion guide, the quad-electrodes (461-464) receiving electrical potentials to form the field required to focus and maintain ions at the centre of the ion transport channel defined therein. Quarter-circular insulators (466, 468) may be provided to seal the channel from the interior of the mass spectrometer on all sides over its length. A ceramic heater 314 is provided at the entrance to the ion transfer optics to prevent accumulation of ions on the pole electrodes. A thermal break 312 is provided in the quadrupole, so as to enable heating of the inlet poles 313 while the remainder of the quad 311 is maintained at a reduced temperature.

Title: A motor system with a relay disconnecting the start winding at a voltage threshold
Inventor: WEIHRAUCH NIELS CHRISTIAN
IPC: H02P1/42
Filed: 2013-05-28
Abstract: An AC single phase motor-system comprises a rotor driven by a main winding 4 and an auxiliary winding 5 powered through a start capacitor Cs for driving the rotor during start-up. A potential relay 6 controls a relay-switch 7 which deactivates the start capacitor Cs when a control voltage across the relay 7 exceeds a threshold. The relay-switch 7 is located so that when the start capacitor Cs is connected, the control voltage depends on the voltage across the auxiliary winding 5, and when the capacitor Cs is disconnected, the control voltage is independent of the voltage across the auxiliary winding 5. A PTC 20 may be included to temporarily bypass the open relay 7. This prevents unstable switching. The motor system may be used in a compressor for a refrigerator.

Title: L2VPN carried in VLAN at ends of IS-IS MAC-in-MAC tunnel
Inventor: RAMESH DEEPAK
IPC: H04L45/50
Filed: 2013-06-21
Abstract: The invention establishes an L2VPN (virtual private network) between access nodes 102,108 via nodes 104,106 of a core network. An adjacency between access and core nodes is determined. Then, a mapping between a VLAN ID (virtual LAN) and a core network I-SID (service instance identifier) is decided by the access node and forwarded to the core node. It may be transmitted as an IS-IS (intermediate system intermediate system) TLV (type length value) message. The core node may distribute I-SID advertisements to the core network and suitable network paths may be calculated. An L2VPN may be established using the VLAN ID and the I-SID. The VPN may use MAC-in MAC tunnelling across the core network. The core node may prevent routing messages from other core nodes from reaching the access node. The core devices may be backbone edge bridges (BEB).

Title: A control system for operating in an absence mode
Inventor: BUNTING SIMON
IPC: H05B37/02
Filed: 2013-06-28
Abstract: A lighting control system 1 for operating in an absence mode or semi-automatic mode comprises a lighting load 3, a presence detector 5 for detecting a person, the detector having a control module 17 arranged to switch off the lighting load in response to the output of a detector element 15 and a switch 9 actuatable from a closed state to an open state. The switch is in series with the detector such that when the switch is in the open state, the power to the detector is interrupted. The switch is biased into the closed state (for example it is a normally-closed push-button (NCPB) switch). The lighting control system is configured such that when the switch has returned to the closed state after actuation, the status of the lighting load is toggled to the opposite of its status prior to actuation of the switch.

Inventor: GUEDROUDJ ABDELHAMID
IPC: E21B43/12
Filed: 2014-02-04
Abstract: A method of modelling/monitoring production through a production separator train involves determining a scaling factor to convert a measured property of production fluid such that the converted measure property is expressed in terms of it having been passed through a reference separator train and applying said scaling factor to a measured property of said production fluid. The step of determining a scaling factor may comprise creating models of the production separator train and of a reference separator train. These models are then used to determine a property of the production fluid subsequent to it passing through the production separator train, and a property of a production fluid subsequent to it passing through the reference separator train.

Title: Processors, methods, and systems to implement partial register accesses with masked full register accesses
Inventor: GROCHOWSKI EDWARD T
IPC: G06F9/30
Filed: 2014-03-26
Abstract: Processor 400 comprises decoder 420 which maps partial register access (PRA) instructions 403 to masked full register access (MFRA) instructions. PRA instructions 403 indicate source and destination packed data operands which are narrower (e.g. 128-bit) than the operands 423 of MFRA instructions (e.g. 512-bit). Execution unit 409 performs MFRA instructions using packed data operation mask 408. Results of the MFRA operation are stored in a wider destination operand 425 (e.g. 512-bit). Result data elements corresponding to the MFRA operation but not to elements 422 corresponding to the PRA instruction 403 (e.g. bits 512:128) are masked out. Such result data elements may preserve their original value. This way backward compatibility is ensured to support older instructions utilising narrower packed data operands e.g. for SIMD or vector architectures having wider data widths. PRA instructions may specify second source narrower operands and operations on pairs of non corresponding data elements.

Title: Threshold transition detector, RMS measurement and filter
Inventor: MIDDLETON GREGORY
IPC: G01R23/02
Filed: 2014-07-30
Abstract: A threshold transition detector for detecting a transition of an analogue signal across a threshold comprises an analogue to digital convertor (ADC) 404, a digital filter 406 and a comparator 408 arranged to receive the filtered data and switch an output of the comparator to a first state in response to a value of the data exceeding a first threshold (504, figure 5) and switch the output of the comparator to a second state in response to a value of the data being below a second threshold (502, figure 5). The transition detector may be used to sense zero crossings of the waveform from an electrical generator e.g. to measure frequency. Having two thresholds improves the response of the detector to signals with noise or distortion (figure 3). Also disclosed are methods for filtering digital data for display to reduce updating when consecutive values change by less than a predetermined amount and account for large jumps in value more quickly.
