Title: Memory synchronization filter
Inventor: Jonathan beard
IPC: G06F12/0868
Filed: 2016-12-07
Abstract: Data synchronization between memories of a data processing system is achieved by transferring the data blocks from a first memory to a second memory, forming a hash list from addresses of data blocks that are written to the second memory or modified in the second memory. The hash list may be to identify a set of data blocks that are possibly written to or modified. Data blocks that are possibly modified may be written back from the second memory to the first memory in response to a synchronization event. The hash list may be updated by computing, in hardware or software, hash functions of an address of the transferred or modified data block to determine bit positions to be set. The hash list may be queried by computing hash functions of an address to determine bit positions, and checking bits in the hash list at those bit positions.

Title: Systems and methods for coordinating rendering of a remote audio stream by binaural hearing devices
Inventor: GEORG DICKMANN
IPC: H04R25/00
Filed: 2018-12-14
Abstract: The binaural hearing system includes first and second hearing devices wirelessly coupled by way of a binaural communication link. The first hearing device determines that a signal quality measure of a wireless signal transmitted by a remote audio source is greater than an upper threshold level. In response both hearing devices enter a binaural wireless audio rendering mode in which they render a remote audio stream from the remote audio source to a user. While operating in the binaural wireless audio rendering mode, if both hearing devices determine that a signal quality measure of the remote audio stream drops below a lower threshold level both hearing devices will exit the binaural wireless audio rendering mode. Thus the two hearing devices exit the binaural mode synchronously.

Title: Container
Inventor: PAUL MALCOLM
IPC: B65D43/02
Filed: 2020-08-28
Abstract: A container 10 has a base 20 and a lid 30, a ridge (60, fig. 4) extending around the periphery of the base and projecting upwardly, and a downwardly facing channel (70, fig. 5) extending peripherally around the lid. The ridge and channel are mutually engageable to provide closing of the container. In one independent claim, the lid has a skirt (80, fig. 4) extending downwardly around the inside of the channel and inside the ridge when the lid is closed. The skirt extends at least as far downwardly as the ridge does upwardly. In another independent claim, the ridge extends upwardly from its base and has a wedge-shaped cross section that is narrower at the base (64) and wider at the peak (66). The channel has a wedge-shaped cross-section defining a wider ceiling at the top and a narrower open mouth at the bottom. The channel can deform to enable the mouth to open to pass over the peak of the ridge and, thereafter, to provide a closing force pulling the channel downwardly on the ridge.
