Title: Psychoacoustics for improved audio reproduction and speaker protection
Inventor: Ziad Ramez Hatab
IPC: H04R3/00
Filed: 2016-06-24
Abstract: Psychoacoustic models may be applied to audio signals being reproduced by an audio speaker to reduce input signal energy applied to the audio transducer. Using the psychoacoustic model, the input signal energy may be reduced in a manner that has little or no discernible effect on the quality of the audio being reproduced by the transducer. The psychoacoustic model selects energy to be reduced from the audio signal based, in part, on human auditory perceptions and/or speaker reproduction capability. The modification of energy levels in audio signals may be used to provide speaker protection functionality. For example, modified audio signals produced through the allocation of compensation coefficients may reduce excursion and displacement in a speaker; control temperature in a speaker; and/or reduce power in a speaker.

Title: Image down-scaling with pixel sets selected via blue noise sampling
Inventor: LI-YI WEI
IPC: G06T3/40
Filed: 2018-10-25
Abstract: A blue noise sampling operation identifies source pixels from an input image defining respective pixel sets. Each pixel set is associated with a respective weight matrix 322 and 324 for a down-scaling operation. The blue noise sampling operation causes an overlap region between first and second pixel sets. The computing device assigns overlap pixels 332 and 334 in the overlap region to the first weight matrix based on the overlap pixel being closer to the first source pixel 302. The second weight matrix is modified to exclude the overlap pixels from a portion of the down-scaling operation involving the second weight matrix. The down-scaling operation is performed on the input image by combining the first pixel set into a first target pixel with the first weight matrix and combining the second pixel set into a second target with the modified second weight matrix.

Title: Composite mould and related aspects
Inventor: KIREN PASSI
IPC: B29C70/74
Filed: 2019-04-24
Abstract: A composite mould comprises at least two separable mould layers which, when aligned, form one or more recesses for retaining a liquid moulding substance 8. The moulding substance 8 may escape between the aligned layers as pressure builds such as during moulding-substance solidification. The mould may be used to apply a design pattern to a flexible material or fabric using a silicone base moulding-substance. A gap 30 may be created between the layers if pressure rises above a threshold, which is less than the pressure at which moulding substance can escape between the mould surface and a substrate onto which the material is being moulded. This prevents escape of moulding substance onto the substrate resulting in a better-defined design pattern. At least one adjacent mould surface of the layers may have a surface roughness which facilitates the moulding-substance escape. The moulding substance may include additional components such as electronic (such as sensors) or decorative components or engagement parts of a fastener, which are retained in a three-dimensional design sheet moulded using the mould. The mould may be used to apply a design to protective, sports or dance clothing or to produce a sensor surface material for parts of a robot.
