Abstract: A method includes determining an error after attempting to read, via a first read transducer and a second read transducer, a data sector in a first data track. The method further includes calculating a weight ratio associated with the data sector and determining a read offset direction of the data sector based, at least in part, on the calculated weight ratio.

Abstract: Operations are monitored that involve a plurality of servers coupled to a plurality of data storage enclosures via a rack-level, storage networking fabric. The servers are operable to provide data storage services utilizing the data storage enclosures via a network. The data storage enclosures each have one or more data storage devices. The servers and the data storage enclosures are mounted within a data center rack. A failed unit determined that includes a failed one of the servers or a failed one of the data storage devices within a selected one of the data storage enclosures. A replacement is found for the failed unit within the data center rack, and the replacement is established for the failed unit within the data center rack. The establishment of the replacement involves establishing a new connection via the storage networking fabric.

Abstract: Method and apparatus for using light detection and ranging (LiDAR) to assist the visually impaired. In some embodiments, a LiDAR system is affixed to a selected finger of a user and used to emit light pulses within a field of view (FoV) before the user. Reflected pulses are detected to generate a point cloud representation of the FoV. A sensory input is provided to the user that describes the point cloud representation of the FoV. The sensory input may be haptic, auditory or some other form. In some cases, a glove is worn by the user and a separate LiDAR system is affixed to each finger portion of the glove to provide a composite scanning and detection operation. Preconfigured hand gestures by the user can be used to change the operational configuration of the system.

Abstract: An integrated circuit includes a read/write channel and a servo controller. The read/write channel is configured to: determine, in connection with a first path, respective read errors associated with N number of the data sectors; estimate respective offset positions of the N number of the data sectors; and generate a second path based, at least in part, on the respective estimated offset positions. The servo controller is configured to cause adjustment of a position of a read transducer based on the second path.

Abstract: Apparatus and method for enhancing resolution in a light detection and ranging (LiDAR) system. In some embodiments, an emitter is configured to emit a first beam of light pulses over a baseline, first field of view (FoV). Responsive to an activation signal, a controller circuit directs the emitter to concurrently interleave a second beam of light pulses over a second FoV within the first FoV. The first and second beams may be provided at different resolutions and frame rates, and may have pulses with different waveform characteristics to enable decoding using separate detection channels. The interlaced beams provide variable scanning of particular areas of interest within the baseline FoV. The second beam may be activated based on range information obtained from the first beam, or from an external sensor. Separate light sources operative at different wavelengths can be used to generate the first and second beams.

Abstract: A light detection and ranging system can have an avalanche photodiode detector positioned between at least one pair of non-avalanche photodiode detectors with each detector connected to a photon controller. The photon controlled may selectively activate one or more detectors to determine an alignment of photons emitted by one or more emitters.

Abstract: A light detection and ranging system can have a light source coupled to a polygon reflector having a plurality of facets. A controller can be connected to the light source and directed to generate and execute a calibration strategy that alters an orientation of the light source in response to identification of a position of at least one facet of the plurality of facets.

Abstract: A light detection and ranging system can have a light source coupled to a reflector consisting of a waveguide. The waveguide may be tuned to a selected polarization by a controller to block retroreflected photons resulting from a light beam emitted from the reflector. The waveguide polarization can be altered over time by the controller to provide customized blocking of photons.

Abstract: A heat-assisted magnetic recording head includes a near-field transducer (NFT). The NFT includes a plasmonic disk and a near-field oscillator pair. The near-field oscillator pair includes a receiving oscillator and an emitting oscillator. The receiving oscillator is operatively coupled to the plasmonic disk and configured to receive localized surface plasmons from the plasmonic disk and amplify a near field of the localized surface plasmons. The emitting oscillator is configured to receive the near field from the receiving oscillator and emit the near field toward a surface of a magnetic disk.

Abstract: A light detection and ranging system can have a metasurface that continuously extends between a pair of electrical contacts. The metasurface may be separated from an underlying silicon substrate by an air gap with the silicon substate doped with a P-i-N configuration to create electrostatic force that alters a size of the air gap in response to a voltage bias between the pair of electrical contacts.
