Abstract: This disclosure provides techniques hierarchical address virtualization within a memory controller and configurable block device allocation. By performing address translation only at select hierarchical levels, a memory controller can be designed to have predictable I/O latency, with brief or otherwise negligible logical-to-physical address translation time. In one embodiment, address transition may be implemented entirely with logical gates and look-up tables of a memory controller integrated circuit, without requiring processor cycles. The disclosed virtualization scheme also provides for flexibility in customizing the configuration of virtual storage devices, to present nearly any desired configuration to a host or client.

Abstract: A two-terminal electrical protective device operates by harvesting energy from a small but non-zero voltage drop across a closed solid-state switch. From a default, open-circuit state, the device is remotely triggered by an AC signal to enter the desired conductive state. Power scavenged by an energy harvesting circuit while the device is in the conductive state, powers a gate drive circuit to hold the device in the conductive state for as long as current flows. When current stops, the device returns to the default open-circuit state.

In one example, a method includes receiving a first sequence of images associated with a scene and captured during continuous rotation of an image sensor. Each image of the first sequence has a portion that overlaps with another image of the first sequence. The method further includes generating a first panoramic image. The generating includes processing a second sequence of images based on a point-spread function to mitigate blur associated with the continuous rotation to obtain a deblurred sequence of images, and processing the deblurred sequence based on a noise power spectral density to obtain a denoised sequence of images. The point-spread function is associated with the image sensor's rotation speed. The second sequence is based on the first sequence. The first panoramic image is based on the denoised sequence.

Abstract: A cache memory subsystem includes a virtually-indexed virtually-tagged first-level data cache (L1D) and a physically-indexed physically-tagged second-level set-associative cache (L2). Each L2 entry is uniquely identified by a set index and a way number. The cache memory subsystem has an inclusive allocation policy. When a snoop request that specifies a physical memory line address hits in an entry in the L2, the cache memory subsystem forwards the snoop request to the L1D but substitutes a physical address proxy (PAP) for the physical memory line address. The PAP specifies the way number and the set index of the hit entry in the L2. To process the forwarded snoop request, the L1D uses N bits of the PAP to select S sets and uses the remaining PAP bits (diminutive PAP) for comparison with a diminutive PAP stored in each valid entry of the S selected sets.

Abstract: An actuator-controlled strike comprising a housing disposable within a doorframe and including a cavity for a spring latch and a dead latch of a mortise-type lockset. A keeper is pivotably mounted within the chamber to engage the spring latch. A pivotably mounted kicker cooperates with the keeper. A pivotably mounted dead latch release is supported by the keeper when the spring latch is within the strike. The keeper is released by the actuator and rotates into a position to ramp the spring latch out of the strike, also allowing the dead latch release to release the dead latch into the cavity, allowing the spring latch to be ramped out of the strike. Pivoting the keeper causes the kicker to urge the spring latch onto an exit ramp on a face of the keeper. The dead latch release can be installed in a plurality of different locations in the housing.
