Inventor: Chung Chun Wan
IPC: H04N5/232
Filed: 2015-11-17
Abstract: A time-of-flight camera system is described. The time-of-flight camera system includes an illuminator to illuminate a region within the time-of-flight camera system's field of view. The time-of-flight camera system includes an image sensor to receive optical signals from the illumination for determining depth profile information within the field of view using time-of-flight measurement techniques. The image sensor has circuitry to determine one or more regions within the field of view where a received optical signal from the illuminating was weak. The illuminator is also to re-illuminate the one or more regions with stronger light than the one or more regions received during the illuminating. Each of the one or more regions being smaller than the region. The image sensor is also to receive optical signals from the re-illumination for determining depth profile information within the one or more regions.

Title: Vector interleaving in a data processing apparatus
Inventor: MBOU EYOLE
IPC: G06F9/30
Filed: 2017-07-20
Abstract: A microprocessor includes a vector instruction that performs an operation (see operations 38, 36, 42 or 40) on selected input data pairs taken from a first and a second source register (30 and 32) and stores a result data vector in a destination register 34. Result data which originate respectively from the first source register and the second source register are interleaved i.e. they are stored in alternating positions in the destination register. The operation may be an arithmetic, logical or shift operation. The vector interleaving instruction may further specify predicate bits which may be used to selectively suppress input bits (fig 5B). A further arrangement concerns a data processing operation where input data are taken from diagonally adjacent elements of a first and second source registers (fig 6). Such vector instructions may be used to accelerate polynomial multiplication, for example a carry-less multiplication (e.g. the Karatsuba approach, fig 7).

The system may determine whether water is covering the lens or a users hand touching the lens to unlock the boot by determining whether the capacitance signal measured by the ITO coating is above a threshold level for a period of time. The system may determine whether the obstruction is condensation or ice and hence heat the coating for different periods of time 522, 526. The heater may be run when the engine of the vehicle is off. When the system is in a detecting state 504 (i.e. a user input or obstruction), it may prevent the heater from running.

Abstract: A method of and apparatus for indicating a visible skin condition requiring medical attention comprises the provision of (i) a probe 201 with a plurality of electrodes, a strobing circuit and a monitoring circuit, alongside (ii) a data processing system 202. A reference region 203 of skin that does not include the said skin condition is identified and the probe 201 is deployed against this region to produce reference data 213 from reference output signals 212.

Title: Method of using a blockchain
Inventor: CRAIG STEVEN WRIGHT
IPC: G06Q50/18
Filed: 2019-03-04
Abstract: A blockchain is used to evidence that a first party agrees to a statement or document, such as a deed, will or other legal document. A second party or witness receives confirmation that the first party or signatory agrees to the document, e.g. orally by video or mobile phone call. The witness receives information from the signatory, but this information is withheld until after the signatory has generated a cryptographic signature and provided their confirmation of agreement. Once the information is available to the witness, the witness attests to receipt of the signatory’s confirmation by generating a cryptographic signature based on the previously withheld information. Each of the parties’ cryptographic signatures is included in at least one blockchain transaction, and each transaction is propagated to the blockchain network nodes upon meeting a validation condition. The validation condition requires that each party’s cryptographic signature is included in at least one transaction and that the witness’ signature was generated by signing the withheld information. The transaction locking and unlocking scripts guarantee that the witness cannot provide their signature and attest to the signatory’s agreement until after the signatory has provided both their cryptographic signature and confirmed their agreement with the document.
