Title: Method and apparatus for enhancing a hibernate and resume process using user space synchronization
Inventor: PRESTON JOHN B
IPC: G06F9/44
Filed: 2013-03-04
Abstract: Before hibernating a computing device (102), system software components (116) are notified of an upcoming hibernation process. The notifications are conveyed through an application program interface (API) (114). At least a portion of the system software components (116) can perform one or more pre-hibernation activities to place that system software component (116) in a ready-to-resume state. Each system software component indicates when it is ready for hibernation. Responsive to receiving the indication from each of the system software components (116), the hibernation process can complete. The completed hibernation process creates a snapshot (122) in nonvolatile memory. The snapshot (122) saves state information (124) for each of the system software components (116). The state information (124) is for the ready-to-resume state of the system software components (116). The computing device (102) can be restored after hibernation using a resume process (130), which reads the state (124) information from the snapshot (122).

Title: Modulated Flame Gas Flow Rates In Flame-Based Detectors
Inventor: FOGWILL MICHAEL
IPC: G01N30/68
Filed: 2014-10-06
Abstract: A method for maintaining flame characteristics in a flame-based detector, the method comprising: providing a chromatographic system 1000 having a mobile phase flow stream in fluid communication with the flame-based detector1060 and upstream of the detector. The mobile phase flow stream entering the flame-based detector has an adjustable mass flow rate. The method also includes determining a mass flow rate of a non-combustion portion of the mobile phase flow stream entering the flame-based detector; and adjusting a mass flow rate of a combustion gas entering the flame-based detector in response to the mass flow rate of the non-combustion portion of the flow stream entering the detector to maintain the flame characteristics. The combustion gas is adjusted with respect to the determined mass flow rate of the non-combustion portion of the flow stream. Further methods for maintaining flame characteristics in a flame-based detector are also disclosed. Advantageously the methods substantially eliminate and/or reduce variability in the flame-based detector response when performing density gradient separations.

Patent GB-2536279-A (GB)
Title: Transmission for energy storage device
Inventor: DANIEL RICHARD JONES
IPC: F16H3/097
Filed: 2015-03-12
Abstract: A transmission, for an energy storage and recovery system, comprises a variable slip transmission 9 and a clutch 5 arranged in series to transmit drive while slipping. The variable slip transmission 9 and clutch 5 transmits torque from an energy storage device, e.g. flywheel 1, and an energy source and/or sink, such as drivetrain coupling 7. A level of torque transmitted through a slipping clutch 5 is dependent on a clutch force but is independent of clutch slip speed. Preferably the clutch 5 is provided by a plurality of clutches connected in parallel in a range extender (11, fig 2). When drive is transferred between clutches in parallel, the clutch forces of both clutches are controlled to maintain a total torque transmitted by the clutches. This reduces torque fluctuations at the energy source/sink 7 during clutch transfer. Where there are two slipping clutches in series, one clutch is controlled to provide the required torque and the other clutch is controlled in response to a clutch slip speed. This controls a speed of rotation of a mass between the clutches.

Title: Speaker-adaptive speech recognition
Inventor: RAMA DODDIPATLA
IPC: G10L15/16
Filed: 2016-01-18
Abstract: A test-speaker-specific automatic speech recognition (ASR) system uses training data spoken by the test speaker to train an adaptive model. The first stage comprises an input network component (eg. 3 layers of neurons in a Deep Neural Network DNN, 18 fig. 3) and a respective training-speaker-specific (TSS) adaptive component (typically comprising fewer than 10% of the input network neurons and often referred to as a bottleneck layer, 19 fig. 3) which act as a feature extractor, these being trained and output (21, fig. 3) generically, ie. without speaker-specific adaptation. The derived features are then input to a second stage comprising an input network, a TSS, and a speaker-adaptive output component 4 (eg. 3 more layers of neurons as in 22, fig.3). In one embodiment a first pass trains a speaker-independent DNN 2 to generically recognise tri-phones 5 which are converted to simple phones 6 in order to train the TSS (specific) bottleneck layer 7 which inputs to an ASR engine 8 also fed by a trained TSS DNN, and the model periodically updated 9. Thus each speaker has their own bottleneck layer (19i in fig. 5).

Title: Intelligent cash drawer unit or cash register and methods of operation therefor
Inventor: MARK BERNHARDT
IPC: G07G1/00
Filed: 2017-09-13
Abstract: An intelligent cash drawer unit or cash register operable to process signals from load cells beneath note/coin cups when the drawer is open. It then determines the weight and value of cash in the cups, in order to allow a float to be added, or a lift to be made, stepwise, whilst the drawer remains open. The float or lift mode can be entered through receiving a signal indicative of user input. A sensor can detect whether the drawer is open or closed. A threshold weight for each of the cash cups in the cash drawer can be stored in memory, representing the weight that it is allowable to add or remove in a single step or action, and a comparison of the added/removed weight to the threshold weight causes a validation or error signal to be output. Readings from each of the cash holding cups can be stored together with the time when it is detected that the reading is stable. If a stable reading is not collected before the drawer is closed, a stable reading can be stored from when the drawer is closed. An audible alert can be generated to confirm the float or lift mode.

IPC: H03K17/16
Filed: 2018-04-20
Abstract: A power conversion circuit 100 comprises first and second semiconductor switches 102, 104, and a drive circuit 114 configured to create a period of operational overlap for the first and second switches. The drive circuit sets a gate voltage of the first switch to an intermediate value VInt above a threshold voltage VThreshold of the first switch during turn-ON and turn-OFF operations of the second switch. A method of operating first and second semiconductor devices (Fig.4) comprises reducing a gate voltage of the first device to an intermediate value above a threshold voltage while the second device is OFF, turning OFF the first device after the second device is ON, increasing the gate voltage of the first device to the intermediate value while the second device is ON, and fully turning ON the first device after the second device is OFF. The semiconductor switches may be metal oxide semiconductor field effect transistors (MOSFETs) comprising a wide band gap (WBG) material, e.g. Silicon Carbide, SiC. These devices are susceptible to high frequency oscillations, or ringing, during switching, and it is desirable to minimize ringing to avoid inducing electromagnetic interference (EMI) noise to surrounding circuitry. The power conversion circuit may be used in power converters and inverters, or power modules that may be included in electric vehicles.
