Title: Generating, transmitting and receiving object detection metadata
Inventor: SINGER DAVID WILLIAM
IPC: G06F17/30
Filed: 2011-06-13
Abstract: A perimeter (105) around a detected object, such as face (103), in a video frame 1309 is generated in a first coordinate system. The perimeter is converted from the first coordinate system into a second coordinate system having the same aspect ratio as the first coordinate system. A first metadata entry includes dimensions of the image data in the second coordinate system. A second metadata entry provides a location and dimensions of the converted perimeter in the second coordinate system. Additional metadata can indicate matching objects between frames, position of an object relative to other objects in a frame, a probability that an object is correctly detected, and a total number of objects detected across multiple frames of image data. Claims are also included for the transmitting and receiving of the generated metadata.

Title: Rolling Mill Temperature Control
Inventor: LITTLER DAVID JAMES
IPC: B21B27/08
Filed: 2012-05-19
Abstract: For controlling the temperature of the working rolls and hence the flatness of the material during the rolling of aluminium strip or foil, the system consists of a set of internally cooled work rolls 3 , and a means 7 to externally heat these rolls by induction heating. The rolls are internally cooled by means of circulation of cooling medium 6.

Title: Reducing inter-cell interference for base stations employing power boosted virtual carrier transmissions
Inventor: WAKABAYASHI HIDEJI
IPC: H04L5/00
Filed: 2013-01-16
Abstract: Downlink communications from a base station (BS) in a wireless telecommunications system to terminal devices are made using a plurality of OFDM sub-carriers spanning a system frequency bandwidth. The BS supports communications with a first type of terminal device on a host carrier using OFDM sub-carriers distributed across the system frequency bandwidth and supports communications with a second type of terminal device on a restricted bandwidth carrier using OFDM sub-carriers distributed across a restricted frequency bandwidth which is smaller than and within the system frequency bandwidth (Virtual Carriers, VC). The BS receives from a further (neighbour) BS an indication of a transmission characteristic to be used by the further BS for transmissions to the second type of terminal device using a reduced bandwidth carrier associated with the further BS. The BS selects a transmission characteristic for its own transmissions to be made to the second type of terminal device using the restricted bandwidth carrier in a manner that takes account of the indication of the transmission characteristic received from the further BS. The BS then conveys an indication of the transmission characteristic from the BS to at least one other (neighbouring) BS. Thus, the respective BSs exchange information regarding their restricted bandwidth carrier transmissions to help them coordinate their respective transmissions with a view to reducing inter-cell interference.

Title: Authorisation of a visiting wireless communication unit by transferring personal data to an authorised wireless communication unit
Inventor: KILGOUR CHRISTOPHER EDWARD JOHN
IPC: H04W4/80
Filed: 2013-02-27
Abstract: When a new or visiting wireless communication unit requests authorisation to access a small cell, such as a Femto cell, then an authorised wireless communication unit (for example a master unit) receives and accepts the visiting wireless communication unit's request. It then performs a physical contact-enabled or contactless vicinity-based data transfer (this may include bumping the units together, near field communication (NFC), Bluetooth(RTM), Infra-Red (IRDA) or other short range wireless technology) of subscriber data from the visiting wireless communication unit. The master wireless device may then authorise the visiting wireless communication unit at the wireless communication unit to access the network. This removes the need for an owner of the Femto cell to manually update the whitelist or the closed subscriber group (CSG) access list to add the visiting wireless device.

Title: Color image sampling and reconstruction
Inventor: TAY HIOK NAM
IPC: G06T3/40
Filed: 2011-09-25
Abstract: An image capture apparatus that includes an array of color filters for green, red, and magenta colors arranged over a semiconductor substrate in the manner of a primary color Bayer pattern except a magenta color replaces the blue color. Light passing through the magenta color filter is integrated separately in a magenta pixel for a shallow photodiode signal and a deep photodiode signal in a first photodiode and a deeper second photodiode in the substrate, respectively. A mezzanine photodiode may be disposed between the first and second photodiodes and held at a fixed voltage level or reset multiple times during charge integration. A red pixel value for the magenta pixel is a function of the deep photodiode signal and an adjacent red pixel's red pixel signal. A minimum exists in its derivative with respect to the former at a value of the former that varies with the latter.
