Abstract: A light detection and ranging system can consists of an optical emitter and optical detector each connected to a controller. An isolator may be coupled to the optical emitter and be constructed of photonic crystals that exhibit a high group index to allow broadband operation with a reduced physical length.

Abstract: A recording head comprises a write pole extending to an air-bearing surface. A near-field transducer is positioned proximate a first side of the write pole in a down-track direction. A heatsink structure is proximate the near-field transducer and positioned between the near-field transducer and the write pole. The heatsink structure extends beyond the near-field transducer in a cross-track direction and extends in a direction normal to the air-bearing surface.

Abstract: A data storage ecosystem that includes a series of devices of increasing size, designed to look and work together as a family, with at least one of the devices being a data storage device having a first consumer-accessible connector and a second high speed connector. The data storage ecosystem also includes a rack-mounted docking unit having a third high speed interfacing connector configured to couple to the second high speed connector of the data storage device when the data storage device is inserted into the rack-mounted docking unit.

Abstract: A data storage system can utilize one or more data storage devices that employ a solid-state non-volatile read destructive memory consisting of ferroelectric memory cells. A leveling strategy can be generated by a wear module connected to the memory with the leveling strategy prescribing a plurality of memory cell operating parameters associated with different amounts of cell wear. The wear module may monitor activity of a memory cell and detect an amount of wear in the memory cell as a result of the monitored activity, which can prompt changing a default set of operating parameters for the memory cell to a first stage of operating parameters, as prescribed by the leveling strategy, in response to the detected amount of wear.

Abstract: A non-volatile memory (NVM) is formed of memory cells each having multiple ferroelectric memory elements (FMEs). Each FME stores data in relation to an electrical polarity of a recording layer formed of ferroelectric or anti-ferroelectric material. Each multi-FME memory cell is coupled to a set of external control lines activated by a control circuit in a selected order to perform program and/or read operations upon the FMEs. The FMEs may share a nominally identical construction or may have different constructions. Data are programmed and written responsive to the respective program/read responses of the FMEs. Constructions can include ferroelectric tunneling junctions (FTJs), ferroelectric random access memory (FeRAM), and ferroelectric field effect transistors (FeFETs). The NVM may form a portion of a data storage device, such as a solid-state drive (SSD).

Abstract: Systems and methods are disclosed for synchronous writing of a grain patterned medium. The systems and methods can be implemented within a data storage device having a grain patterned medium. Further, a calibration process to determine a count of bits between servo wedges can be implemented in manufacturing, within the data storage device, or both. In some examples, the data storage device, during operation, can utilize the count of bits to perform synchronous writing, determine write errors, or both. Further, the servo wedge of the grain patterned medium may be patterned with a same or similar grain pattern as the data area that follows the servo wedge. Such a data storage device can implement a single clock for reading a servo wedge and writing a data area.

Abstract: Use of computational storage drives (CSDs) in a machine learning pipeline. The CSD may include a machine learning coprocessor capable of natively executing a machine learning model on raw data stored locally at the CSD. In turn, one or more lower order machine learning operations may be executed at a CSD in response to a read/transform command issued by a host. In turn, the CSD may return transformed data comprising data or metadata that is an output of the lower order machine learning operations. This approach may allow for application of a machine learning model locally to input data stored on the CSD having the machine learning coprocessor. This may avoid network bandwidth associated with traditional read and write operations for input and output data from a machine learning pipeline. Moreover, use of CSDs may provide highly parallelized processing using CSDs for application of machine learning operations at the edge of a network.

Abstract: Technology disclosed herein provides an object tracking multi-camera system including a plurality of cameras to capture images of one or more objects and one or more pattern recognition modules, each of the pattern recognition modules configured to identify an object in a video frame using pattern recognition and assigning a tracking number to the identified object, collect a plurality of object frames related to the identified object and associating the plurality of object frames to the assigned tracking number, compare a newly obtained object frame with the plurality of object frames related to the identified object to determine if the newly obtained object frame is related to the identified object, and in response to the comparison determine that facial recognition does not need to be performed on the newly obtained object frame.

Abstract: Apparatus and method for device and data authentication in a computer network, such as but not limited to an IoT (Internet of Things) network. In some embodiments, a trust hub device is coupled to an interconnectivity device. The trust hub device includes a controller and non-volatile memory (NVM), and may be a network capable data storage device. The interconnectivity device is configured as an Internet of Things (IoT) or Operational Technology (OT) device, and includes a controller and a sensor. Data from the sensor are transferred from the interconnectivity device to the trust hub device. The trust hub device proceeds to attest a provenance of the data from the sensor to a remote entity associated with the interconnectivity device. The trust hub device includes a firewall to the external network, establishes a root of trust for the local interconnectivity device, and performs enrollment and signing services for the interconnectivity device.
