Title: Stepped thickness change in dome-shaped diaphragms for loudspeakers or microphones
Inventor: ROUSSEAU MARTIAL ANDRA ROBERT
IPC: G10K13/00
Filed: 2012-09-18
Abstract: The diaphragm (I 4, fig 4) for a loudspeaker drive unit or for a microphone comprises a rigid. dome-shaped member having a thickness that varies from a first thicker thickness at a first location 30 at the periphery of the dome-shaped member to a second thinner thickness at a second location 40, nearer to the centre of the dome-shaped member. There is a step-wise change in thickness at a location 36 (50, fig 2) between the first location and the second location. The diaphragm may be a two-piece construction, or a one-piece construction. Having greater thickness at the periphery of the dome-shaped member may improve stiffness of the diaphragm and may allow for an increased. break-up frequency . Having thinner material elsewhere in the dome-shaped member may allow the mass of the diaphragm to be kept low and may result in better acoustic sensitivity.

Title: Synchronous Conference System with aggregation of temporally proximate messages
Inventor: CASTELLUCCI ANTONIO
IPC: H04L12/58
Filed: 2013-01-22
Abstract: Synchronous conference systems (aka instant messaging (IM) or internet/text chat (eg. IRC)) transmit messages substantially instantaneously across networks. A message sender may produce a flurry of short messages (IM2-4, IM5-6 and IM7-10) on a subject in rapid succession (see Fig. 2). The recipient may be inconvenienced by having to digest all the messages in order to understand the senders overall intent. They may also prepare and/or send responses that are superseded by further messages from the sender. The invention proposes combining messages separated by short time intervals into aggregate messages (AM2-4, AM5-6 and AM7-10) that are delivered to the recipient en-masse. The merging of messages can also be applied to multiple streams (see Fig. 5).

Title: Method of and apparatus for displaying an output surface in data processing systems
Inventor: CROXFORD DAREN
IPC: G09G5/393
Filed: 2014-04-17
Abstract: A compositing display controller 20 provides an output frame 23 to a display for display by sending respective output surface regions 21, 21a that together form the output frame. Each respective region 24 of the output surface is generated from a respective region or regions of one or more input surfaces, to the display. When a new version of an output surface region is generated, the display controller determines whether the output surface region is unlikely to change or has been unchanged for a period, and if it has, then stores the generated output surface region in a frame buffer 22. Then, for the subsequent frame, checks are performed to see if the output surface region could have changed. If there is no change the stored version of the output surface region is reused, but if there is a change in the output surface region, the output surface region is regenerated. The display controller can provide a hybrid window compositing system that selects between frame buffer composition and direct composition which reduces bandwidth.

Inventor: FRANCK DENOUAL
IPC: H04N19/36
Filed: 2015-06-16
Abstract: The invention relates to a method for obtaining media data and metadata from an encapsulated bit-stream resulting from the encapsulation of one or more bit-streams, the media data of each of the one or more bit-streams being organized into one or more layers, each layer comprising timed samples or sub-samples. A data structure is obtained for referencing metadata including at least one definition of at least one group of timed samples of the media data. At least one operating point descriptor is obtained for each of the one or more bit-streams, the at least one operating point descriptor providing metadata related to descriptive information enabling timed samples belonging to a group of timed samples defined in metadata referenced by the data structure to be independently decoded. Each operating point descriptor associated with one group of timed samples defines the descriptive information of the timed samples belonging to the group. The invention makes it possible to dynamically set descriptors for operation points, provide an efficient data organization and track description scheme suitable for especially for handling spatial tiles, scalable layers and multiple views in Layered HEVC for multi-layer video streams and therefore ensure that the result of the ISO BMFF parsing is more efficient and adapted to Layered HEVC.

Title: Aligning multi-view scans
Inventor: NATHAN A CARR
IPC: H04N7/18
Filed: 2015-07-23
Abstract: The invention relates to alignment techniques that automatically align multiple scans or images of an object obtained from different perspectives (different camera angles). The claimed method first forms an alignment of a plurality of scans 402,404 of an object obtained from different perspectives by recognizing keypoint features within the plurality of scans; assigning error values to potential matches between said keypoint features; and, matching keypoint features using the error values to produce the alignment. An error is then associated with combining this alignment with additional keypoint features (e.g. from another scan, 406), and the method determines whether to accept or reject the alignment based upon comparison of the computed error to a threshold, in order to prune potential alignments. Thus instead of relying solely on errors in local feature matching between a pair of scans to identify a best possible alignment, additional alignment or merging possibilities are also considered. The method could produce a global 3D model 408 of the object using the accepted partial alignment.

Title: Vector predication instruction
Inventor: THOMAS CHRISTOPHER GROCUTT
IPC: G06F9/30
Filed: 2016-03-23
Abstract: An apparatus supports vector instructions for which multiple lanes of processing are performed on respective data elements of a vector value. In response to a vector predication instruction, such as VPT, processing circuitry sets control information, such as a vector predicate register (Figure 8), based on the outcome of a number of element comparison operations each for determining whether a corresponding element passes or fails a test condition, such as greater than. The control information controls processing of a predetermined number of subsequent vector instructions after the vector predication instruction. The predetermined number is hardwired or identified by the vector predication instruction. For one of the subsequent vector instructions, such as VMLA, an operation for a given portion of a given lane of vector processing is masked based on the outcome indicated by the control information for a corresponding data element. This may facilitate vectorised loops.
