Abstract: Novel techniques for end-to-end file storage replication and security between file systems in different cloud infrastructure regions are disclosed herein. In one embodiment, a file storage service generates deltas between snapshots in a source file system, and transfers the deltas and associated data through a high-throughput object storage to recreate a new snapshot in a target file system located in a different region during disaster recovery. The file storage service utilizes novel techniques to achieve scalable, reliable, and restartable end-to-end replication. Novel techniques are also described to ensure a secure transfer of information and consistency during the end-to-end replication.

Abstract: Large, kitchen island cutting board on locking wheels, that provides a safe and proficient food preparation working device for cooks of all skill levels. This invention incorporates a base unit that said device and components reside in and on as described herein. Cutting board height of invention is adjustable, a stand and handle for said cutting board is attached. The cutting board has attached to it stainless-steel deep-dish food pans in folding brackets to hold food items to be prepared and or debris deposited into for disposal. A light fixture above cutting area for convenience and safety is attached to the base unit of the invention.

Abstract: Footwear providing auditory effects based on kinetic events and other sensed conditions includes a power source, an electronic controller coupled to the power source, memory coupled to the controller and operable to store an audio program, an output device coupled to the controller, where the output device includes a speaker, and a sensor coupled to the controller, the sensor being operable to sense a sensed condition comprising a pressure, force, stress, deformation, velocity, acceleration, shock or temperature, or a combination thereof.

Abstract: A low latency metadata subsystem for file systems in low latency (LL) mode in a distributed file storage service (DFSS). An LL server (LLS) may receive metadata requests from an access node of the DFSS. For read operations, the LLS may check a local cache of metadata and, for cache hits, retrieve the metadata from the cache. For cache misses, the metadata may be fetched from the storage subsystem of the DFSS and cached. For write operations, the LLS may write entries into a journal for the file system and notify the access node after the journal entries are committed to the journal; the journal entries are asynchronously committed in the storage subsystem. The access node may communicate with the storage subsystem to perform data reads and writes for the LL file system.

Abstract: Portable headphones system having a headphones set, a portable media device, and a remote control. The headphones set is adapted to directly mount the portable media device such that a digital audio signal is received directly by a digital audio amplifier of the headphones set. The remote control is adapted to receive song and playlist data from the portable media player and to display this information to the user. The user can issue commands to the portable media player and to the headphones set using the remote control.

Abstract: A personal communication system has first and second portable communication devices, each device including a display, a wireless transceiver, a memory having a plurality of stored audio files, a means to select one of the audio files, the audio file selection means being operable to permit a user to select one of the audio files, and an audio speaker. The wireless transceiver of the first device is operable to transmit a signal identifying an audio file selected by the user and the wireless transceiver of the second device is operable to receive the signal, and, upon receipt of the signal, to play the selected audio file on the audio speaker of the second device. The memory includes one or more attributes for each stored audio file, the attributes comprising a sequence attribute, a message type attribute or a target gender attribute.

Abstract: A sensor positioning aid includes a concavely curved transparent dish having a shape congruent with a lower surface of a sensor, and locating means on the dish for establishing external reference positions in relation to the dish. The locating means preferably includes a rim around the dish and markings on the dish. The positioning aid is placed at a selected location on the head, and the sensor is aligned to the head by aligning it to the rim of the positioning aid. The positioning aid is removed, and the head translated in relation to the sensor to place it closely adjacent to the sensor, without reorienting the sensor. The placement aid is removed and measurements are taken using the sensor. If necessary, the sensor is thereafter reoriented by reference to the markings.
