Abstract: An optical engine for a LiDAR system comprises an analog detection channel comprising an avalanche photodiode (APD) optically coupled to light receiving optics and bias circuitry coupled to the APD and configured to adjust a bias set point (BSP) of the APD. Sensors sense disparate environmental factors that impact optical engine performance. Memory stores pre-established APD BSP data including a nominal APD BSP and pre-established dependence data characterizing the impact of disparate environmental factors on the nominal APD BSP. A controller generates, using sensor signals, in-field dependence data characterizing the impact the disparate environmental factors currently have on the nominal APD BSP, calculate an updated APD BSP using the in-field and pre-established dependence data, and shift the BSP of the APD from the nominal APD BSP to the updated APD BSP to enhance optical engine performance.

Abstract: A distributed data storage system can have a plurality of data storage devices connected to a host via a network controller. Receipt of a data access request from the host with the network controller can result in passing the data access request to a predetermined data storage device of the plurality of data storage devices with the network controller without processing the data access request. The data access request may then be satisfied with a device controller of the predetermined data storage device.

Abstract: Improving performance in solid state devices (SSDs) by controlling or throttling the depth of the request queue. In one implementation, a method includes monitoring a request queue in a solid state device (an SSD), the request queue comprising a first request and a second request having an actual time interval therebetween, determining a queue depth for the request queue, determining a target interval based on the queue depth and a target queue depth, and responsive to the actual time interval being less than the target interval, delaying acting on the second request until after the target interval.

Abstract: Systems and methods are disclosed for dynamically adjusting parameters used during a read operation to reduce stress on a read head. In certain embodiments, an apparatus may comprise a read head configured to read data stored to a data storage medium, and a control circuit that controls a parameter of the read head influencing the read head's ability to accurately read data. The control circuit may be configured to extend the working lifespan of the read head by monitoring a read performance of the read head, and adjusting the parameter to reduce the read performance when the read performance is greater than a first threshold.

Abstract: A recording head has a near-field transducer proximate a media-facing surface of the recording head. A write pole has a leading edge proximate to and facing the near-field transducer at the media-facing surface. A magnetic shield faces the leading edge of the write pole at the media-facing surface and is magnetically coupled to the write pole. The magnetic shield has a notch centered over the near-field transducer.
