Title: Security tag for attachment to an article
Inventor: PAUL KANNAN MICHAEL
IPC: G08B13/24
Filed: 2014-12-12
Abstract: A primary portion of a security tag for attachment to an article comprises a locking mechanism 501 for locking a locking-part of a secondary portion of the security tag and a releasing mechanism 502 for releasing the locking mechanism, a control processor 503 of the primary portion activates the releasing mechanism in response to receiving an external signal, e.g. from a mobile telephone or tablet, and an input device 103, for example a push button, on the primary portion instructs the control processor to initiate the release procedure. As part of the release procedure a visual indicator, e.g. a light, may be activated. A method of releasing a security tag is also claimed. The method includes pressing the input device or interacting with it using a mobile device, the security tag sending a signal to the mobile device which includes data about the article, purchasing the article using the device which then sends a return signal to release the locking mechanism when the item has been purchased.
Patent GB-2523270-A (GB)
Title: Micro-channel plate, method for manufacturing micro-channel plate, and image intensifier
Inventor: NAKAMURA KIMITSUGU
IPC: H01J43/24
Filed: 2013-07-11
Abstract: The present invention is characterized in that an electron emission film (36) formed on the inner wall surface of a channel (32) in a base body (31) and an ion barrier film (37) covering the opening on the side of the front surface (4a) of the base body in the channel are integrally formed in the same film-forming process in a micro-channel plate (4) for an image intensifier. Thereby, the electron emission film and the ion barrier film are continuously formed as a strong film so that the ion barrier film can be formed as a thin film. Further, the residue of an organic film that is formed in the manufacturing process is suppressed, and therefore it is possible to control a reduction in performance of the ion barrier film due to the residual organic film. Thus, the ion feedback from a micro-channel plate is minimized and the operating life of an image intensifier can be sufficiently improved.

Title: Patient care pathway shape analysis
Inventor: POWELL DAVID
IPC: G16H50/20
Filed: 2015-06-19
Abstract: A method includes accessing data related to a series of patient events (e.g. medical procedures, diagnoses or medical test results), and determining whether the data accessed is related to a specific condition. Care pathway data for the condition is generated in response to determining that the accessed data is related to the specific condition. The care pathway data for the condition is stored at a custom extension to a relational database. An aspect of the invention includes generating a care pathway shape as a new custom user-defined type (UDT) extension to the SQL Server database. In yet another aspect, the care pathway data for the condition is generated by linking the one or more patient events related to the treatment of the condition. The linked patient events for the treatment of the condition are represented as a single value, and the single value is a care pathway shape. Identifying an effective pathway for the treatment of a particular condition may potentially lead to the development of standardized care pathways for specific conditions.

Title: Elevator
Inventor: GONG ZHU
IPC: B66B5/16
Filed: 2015-12-29
Abstract: An elevator or lift with a braking unit comprises vertically aligned gear 1 held by a horizontal bracket 6 attached to the elevator, which engages with a vertical rack 2 mounted on the elevator shaft. A wheel 3, also mounted on the bracket engages with the rear, smooth surface of the vertical rack. Vertical brackets 7 extend upwards and downwards from the axis of the gear on both sides. The distal ends of these vertical brackets hold the axes of two smaller gears (4, fig 2) that engage with the larger gear. Springs 8 connect the axes off the smaller gears with the axis of the wheel to the rear of the rack and are held in tension by a pin 9. The pin is mounted on the horizontal bracket and can enter and leave holes in the vertical brackets. When the pin leaves these holes, the springs pull the smaller gears towards the rack so that all three gears are engaged with the rack. The smaller gears will also still be engaged with the larger gear. Consequently, none of the gears are able to revolve and the lift cannot ascend or descend relative to the rack.

Title: Fuel filter with temperature bypass
Inventor: JAMES T D MCHATTIE
IPC: F02M37/36
Filed: 2016-11-02
Abstract: A diesel fuel filtration device 10 comprising a filter body defining a main path wherein is arranged a fine mesh filter 28 and, a secondary path provided with a coarse mesh filter 30 and, a switch devise 18, 20. The switch is adapted to open or close the secondary path as a function of the fuel temperature. When the temperature is below a predetermined threshold flow through the secondary path is enabled. This prevents the fine filter from clogging when fuel begins to wax and solidify at low temperatures. The switch device may utilise the principle of temperature shape memory. The main path may remain open when the secondary path is open. The filtration area of the fine mesh may be larger than that of the coarse mesh. The fine mesh is in the range of 20 to 50 microns (micrometre, µm) and the coarse mesh is no smaller than 100 microns. A diesel fuel pump for an internal combustion engine using a temperature controlled filter arrangement is also disclosed.

Title: SDR-based adaptive noise cancellation (ANC) system
Inventor: DAYONG ZHOU
IPC: G10K11/178
Filed: 2017-08-04
Abstract: Providing adaptive noise cancellation by receiving first input signal ds/ia (downlink signal or internal audio) for reproduction through a transducer; receiving a second input signal err from a reference microphone or an error microphone and updating an algorithm for an adaptive filter 34A based, at least in part, on the first input signal, the second input signal and a feedback signal that is based on the output of the adaptive filter. In a first claimed invention the updating step comprises changing parameters of the algorithm based on a signal-to-disturbance ratio SDR (a signal-to-noise ratio) that is based, at least in part, on the first input signal. In embodiments the adaptive filter represents a secondary path response SE(z). Preferably the secondary path estimate is calculated in the frequency domain and depends on a leakage coefficient and a step size parameter. The step size parameter may be increased if the SDR is high (relative disturbance is low) and decreased if SDR is low (relative disturbance is high). In a second claimed invention the updating step comprises processing at least full band information for the input signal in a frequency domain to generate coefficient values for the algorithm and normalising the step size.
