Title: Protecting a MEMS device from excess pressure and shock
Inventor: JENKINS COLIN ROBERT
IPC: B81B3/00
Filed: 2012-11-12
Abstract: A MEMS device, especially a MEMS capacitive microphone, has increased robustness and resilience to acoustic shock. The transducer structure includes a flexible membrane 101 supported between a first volume 109 and a second volume 110. At least one variable vent structure 401 supplements the usual bleed holes 115 and comprises at least one moveable portion which is moveable in response to an excess pressure differential across the moveable portion so as to vary the size of a flow path through the vent structure. The variable vent may be part of the diaphragm 101 or it may lie elsewhere in the device (1101, fig 11). The variable vent 401 is preferably closed in the normal range of pressure differentials but opens at high pressure differentials to provide more rapid equalisation of the air volumes above and below the membrane. The variable vent provides a variable acoustic impedance between the two air volumes. Various vent shapes are discussed

Title: Activation of dormant cells in a wireless communication system
Inventor: CHARBIT GILLES
IPC: H04W24/02
Filed: 2012-12-21
Abstract: A base station causes a dormant cell to transition to an activated state when it receives an indication of a discovery of the cell from a communications device. A measurement report relating to a cell may also cause a transition of the cell to an activated state. Furthermore an indication of scheduled data provided by a base station may cause transition of a dormant cell to an activated state. Cell cycle configuration may also be transmitted between base stations via an X2 interface or to a communications device which uses the cycle for cell discovery. Upon discovery the device may send a cell activation report to a base station during, in some examples, the short active period of the identified cell. The cell may be a new carrier type (NCT) cell, femtocell, secondary cell (Scell), home eNB, CSG cell or remote radio head (RRH).

Patent GB-2510877-A (GB)
Title: Method for cluster management in multiple target tracking
Inventor: PULFORD GRAHAM WILLIAM
IPC: G01S13/72
Filed: 2013-02-17
Abstract: When tracking a large number of targets individually, it is convenient to divide the targets into a number of clusters having a similar target position and maybe velocity. Targets can leave (split from) a subgroup and proceed independently or join (merge with) another cluster. A cluster management method for the automatic generation of sequences of split and merge decisions for a multiple target tracking system comprises a set of input track clusters at time t and a set of output track clusters at time t+1 of arbitrary sizes. All possible pairings between the input and output clusters are evaluated according to a cost function to give a matrix of assignment costs. The cost function accounts for the number of common tracks, the cluster sizes, and whether there is an exact match. The assignment costs are augmented to include the cost of a dummy assignment. A two-dimensional assignment problem (minimization / optimization) based on the matrix of assignment costs is solved to yield a mapping between input and output clusters. The mapping is used to determine the sequence of split and merge decisions that transforms the set of input track clusters into the set of output clusters.

IPC: A47C16/02
Filed: 2013-03-27
Abstract: A wedge-shaped limb support device 501 for alleviating and/or diminishing pressure on, for example a person's foot 504 by elevating an area of the person's leg above a surface while reclining is provided. In an example, the limb support device 501 is configured such that a base of a wedge-shaped body (310, figure 3) has dimensions which are sufficient to permit the body to envelope a patient's lower leg and a wedge angle (106, figure 1) sufficient to raise the patient's heel 505 above the horizontal when the patient is in a supine position. The limb support device is secured in position using straps 502,512. An advantage is that the wedge shaped body (310) is operable to envelope a variety of different sized limbs, for example, lower legs, thereby increasing the usability of the limb support device. A further advantage is that a patient can walk while wearing the limb support device.

Title: System and method for liquid cooling of an engine of a vehicle
Inventor: SUMMERFIELD JANE
IPC: F01P7/16
Filed: 2014-02-04
Abstract: The internal combustion engine cooling system has a radiator 12, primary pump 18, thermostatic valve 19, secondary pump 33 and an auxiliary device 31 such as a transmission system or an electric motor/generator. The radiator has an inlet to receive hot coolant and an outlet fluidly connected sequentially in series with the auxiliary device and secondary pump by an auxiliary conduit 32. The radiator also has a further port fluidly connected to the valve by a multi-directional conduit 17a. The auxiliary conduit intersects the multi-directional conduit at a junction such that the radiator outlet is also fluidly communicated with the valve, the valve being downstream of the auxiliary device and secondary pump. The valve controls a proportion of coolant flowing through the radiator. When coolant in an engine 11 is cold, such as during engine start, the valve prevents coolant from the radiator outlet and further port passing through. Coolant from the outlet thus passes through the auxiliary device to the further port and back to the outlet. Once the engine has warmed-up the valve permits coolant from the radiator outlet and further port to pass. This reverses the direction of coolant flowing in the multi-directional conduit.
