Title: Direct current (DC) and/or alternating current (AC) load detection for audio codec
Inventor: SHATAM AGARWAL
IPC: H04R29/00
Filed: 2016-05-13
Abstract: A portable audio device may be configured to measure the load characteristics of headphones. The device may measure DC and/or AC characteristics of the load including impedance. These characteristics may be measured by an audio component, such as an audio codec chip or integrated circuit (IC) controller, and reported to software or firmware. The software or firmware may then take action based on the measured load characteristics. For example, the load characteristics may be compared to a database of headphones and their known load characteristics to determine a particular headphone model or type of headphone attached to the audio output. The processor may then apply an appropriate equalization curve. Load impedance is measured by applying a test current from current-mode DAC-A 312 and comparing 352 that to a reference current generated by applying another test current from DAC-B 332 to a reference resistor 338. A number of impedance-measuring approaches are discussed.

Title: Cleaning of a 3D printed article
Inventor: PAUL PHILLIPS
IPC: F28G9/00
Filed: 2016-06-20
Abstract: A method of cleaning an article 10 comprising internal channels comprises pumping a cleaning fluid through the internal channels containing particles having a different magnetic permeability to the fluid and detecting perturbation of a magnetic field caused by the particles. The magnetic field is preferably generated by means of an inductive coil and perturbation of the magnetic field is preferably detected as a change of voltage across the inductive coil. The method preferably includes filtering particles out of the fluid using a filter 18 after the detection step and passing the clean fluid back to an inlet of a pump 24 used for pumping the fluid. The method may also comprise attaching the article to a fluid circuit 22, placing the article on a stage 20 and vibrating the stage whilst the cleaning fluid is being pumped into and out of the article. The cleaning fluid may be water containing a detergent and an abrasive. The article may be a 3D printed heat exchanger and the particles may be residual particles from the 3D printing process. Also disclosed is an apparatus for implementing the method.

Title: An acoustic device for forming a wall of sound in a fluid
Inventor: JEREMY ROSS NEDWELL
IPC: H04R1/44
Filed: 2016-07-29
Abstract: Walls of sound are useful in water for guiding fish away from areas. Hitherto, systems have used bubbles of water to facilitate the speed of travel of the sound. Those systems have suffered from the ability to maintain a consistent wall of bubbles and have often been inefficient. The acoustic device comprises an acoustic transducer 2 connected to an acoustic waveguide 16, 18. The waveguide comprises one or more projections, whereby sound generated by the transducer travels along the projection or projections to form the wall of sound. The waveguide may comprise compressible projections formed from neoprene and arranged in a fan or frond shape. Alternatively, the projections may be laminar. The projections could be of different lengths. The location, arrangement and lengths of the projections are all suited to the underwater location to maximise the effectiveness of the wall of sound.

Filed: 2016-10-26
Abstract: A plurality of microphones, mounted to an autonomous vehicle, receive audio streams 502, from which audio features are used to detect a direction to 510, and identify a class for 508 the sound source. If the source is classified as a vehicle 512, obstacle avoidance (i.e. steering, acceleration, braking) with respect to the direction of the sound source is invoked 518. The classification may be carried out using a machine learning model (i.e. deep neural network), which outputs a confidence value relating to the determined classification 512. The system may also comprise cameras for identifying potential obstacles, wherein the sound source may be hidden from the field of view of any camera.

Title: Address translation cache
Inventor: ANDREW BROOKFIELD SWAINE
IPC: G06F12/1027
Filed: 2017-07-31
Abstract: An apparatus has an address translation cache (12, 16), e.g. a translation lookaside buffer (TLB), having a number of cache entries (40) for storing address translation data which depends on one or more page table entries of page tables. Control circuitry (50) is responsive to an invalidation request 70 specifying address information to perform an invalidation lookup operation to identify at least one target cache entry to be invalidated. Control circuitry (50) selects one of a number of invalidation lookup modes 72 to use for the invalidation lookup operation 74 in dependence on page size information indicating the page size of the target page table entry. Page size information may be implied by specifying an address range or translation stage. The different lookup modes correspond to different ways of identifying the target cache entry based on the address information. The invalidation request may be a leaf-and-intermediate exclusive range-specifying request that relates to an intermediate page table entry specifying an address of a next level page and a leaf page table entry specifying an address translation mapping. The invalidation request may specify a single address and page size information indicating a page size of a corresponding page table entry.
