Abstract: An image sensor system may include an array of image sensor pixels. A portion of the image sensor array that includes high dynamic range (HDR) content may be oversampled at a higher rate than the rest of the array to generate multiple sub-frames. When reading out the multiple sub-frames, the charge transfer gate pulse may only be partially asserted so that only a part of the full well charge is drained. Partially asserting the charge transfer gate pulse allows drainage of the high light signals without perturbing the low light signals. The last sub-frame should be read out by fully asserting the charge transfer gate pulse to ensure than the entire well charge is drained. Data collected from the multiple sub-frames may be accumulated using digital accumulation circuitry. The rest of the array can be read out at the nominal frame rate.

Abstract: A server allows pairing of a computing device with a companion computing device so that they may automatically connect to one another in the future. Pairing is accomplished by responding to a user request to pair a particular companion device by identifying computing devices associated with a particular user account, and directing those devices to monitor whether they are in range of a proximity signal (such as a BLUETOOTH® signal). A user interface on the companion device displays a list of devices specific to the user that are in proximity to the companion computing device, so that the user can choose a device to pair with the companion computing device.

Abstract: Disclosed are various embodiments related to stacked memory devices, such as DRAMs, SRAMs, EEPROMs, ReRAMs, and CAMs. For example, stack position identifiers (SPIDs) are assigned or otherwise determined, and are used by each memory device to make a number of adjustments. In one embodiment, a self-refresh rate of a DRAM is adjusted based on the SPID of that device. In another embodiment, a latency of a DRAM or SRAM is adjusted based on the SPID. In another embodiment, internal regulation signals are shared with other devices via TSVs. In another embodiment, adjustments to internally regulated signals are made based on the SPID of a particular device. In another embodiment, serially connected signals can be controlled based on a chip SPID (e.g., an even or odd stack position), and whether the signal is an upstream or a downstream type of signal.

Abstract: Snapshot metadata may include a plurality of pages of nodes, including active nodes and free nodes. It may be determined whether a snapshot metadata object is eligible for de-allocation, for example, of one or more of the pages of its snapshot metadata nodes. This determination may be based on a number of free nodes in the snapshot metadata object, for example, in relation to the quantity of nodes that are included in a snapshot metadata page. This determination may be made based on previous usage of the nodes allocated to the snapshot metadata object, for example, the number of active nodes relative to a total size of the snapshot metadata object. For example, a maximum extent of active nodes during one or more periods may be compared to a current extent of active nodes to determine whether the snapshot metadata object is eligible.

Abstract: A host coupled to a storage system accesses secondary storage coupled to the storage system and to the host by determining if direct data access between the storage system and the secondary storage is operational, the host forwarding commands to the storage system to directly access the secondary storage in response to direct data access between the storage system and the secondary storage being operational, and the host generating modified commands to cause the host to directly access the secondary storage in response to direct data access between the storage system and the secondary storage not being operational. The secondary storage may be a cloud storage. The secondary storage may be a tape emulation unit. The host may directly access data of the tape emulation unit by accessing a storage device of the tape emulation unit. Commands on the host may be modified by a drivers layer on the host.
