A memory module includes memory devices and a configurable command buffer that selects between alternative command ports for controlling different groupings of the memory devices. Memory systems with memory modules incorporating such a command buffer and memory devices support point-to-point connectivity and efficient interconnect usage for different numbers of modules. The memory devices and modules can be of programmable data widths.

Memory module with configurable command buffer

In one embodiment, a computing system may receive an uncompressed image from a camera. The computing system may generate a compressed image by performing a compression process on the uncompressed image, wherein a decompressed image may be generated as a byproduct during the compression process. The computing system may send the decompressed image to a machine-learning model that was trained using decompressed images. The computing system may generate, by the machine-learning model, an output based on the decompressed image. The computing system may provide operational instructions to a vehicle based on the output.

Low latency image processing using byproduct decompressed images

A memory device or module selects between alternative command ports. Memory systems with memory modules incorporating such memory devices support point-to-point connectivity and efficient interconnect usage for different numbers of modules. The memory devices and modules can be of programmable data widths. Devices on the same module can be configured select different command ports to facilitate memory threading. Modules can likewise be configured to select different command ports for the same purpose.

Memory with alternative command interfaces

In one embodiment, an apparatus includes a volatile memory module configured to store vehicle data, and a refrigeration module coupled to the volatile memory module. The refrigeration module includes one or more chambers containing one or more coolant materials. When the one or more chambers are exposed by an exigent situation associated with a vehicle, the one or more chambers are configured to release the one or more coolant materials to lower a temperature of the volatile memory module.

Black box with volatile memory caching

In one embodiment, a method includes, by a computing device of a first sensor receiving synchronization information from a controller. The synchronization information being generated based on a clock of the controller. The method also includes determining, based on the synchronization information, a first offset between a first clock of the first sensor and the clock of the controller; storing the first offset; and synchronizing, based on the stored first offset and the first clock of the first sensor, a first data capture by the first sensor with a second data capture by a second sensor. The first data capture and the second data capture being requested by the controller.

Systems and methods for synchronizing sensor capture

In one embodiment, a computing system receives sensor data from one or more sensors of a vehicle. The computing system determines a metric associated with the vehicle based on the received sensor data. The computing system determines, based on the metric, a length of a transmission cycle of a communication network of the vehicle. The transmission cycle comprises one or more scheduled time periods dedicated for transmitting data from respective first nodes in the communication network. The computing system configures the communication network of the vehicle based at least in part on the length of the transmission cycle to adjust respective occurrence frequencies of the scheduled time periods over multiple instances of the transmission cycle.

Transmission schedule segmentation and prioritization

In one embodiment, an apparatus includes a volatile memory module configured to store vehicle data; a non-volatile memory module coupled to the volatile memory module; and an energy-storage module configured to provide power to the volatile memory module and the non-volatile memory module during a data transfer between the volatile memory module and the non-volatile memory module. The energy is provided to the non-volatile memory module for writing the vehicle data to non-volatile memory. The apparatus further includes a collision-detector module configured to identify a collision event of the vehicle; and a controller coupled to the energy-storage module and the collision-detector module. The controller is configured to initiate a transfer of the vehicle data stored in the volatile memory module to the non-volatile memory module in response to receiving an indication from the collision-detector module that a collision has occurred.

A disk drive is disclosed comprising a disk media, a head stack assembly (HSA) having a head coupled to its distal end, a microactuator used to provide fine position of the head and a voice coil motor (VCM) configured to actuate the HSA over the disk media, and control circuitry. The control circuitry may be configured to move the HSA in an alternating manner across the disk media while actuating the microactuator. One or more performance characteristics of the microactuator may be measured before and after the actuation of the microactuator, and failure may be detected based on the absolute or relative change of the one or more performance characteristics.

Disk drive detecting crack in microactuator

A head gimbal assembly (HGA) for a disk drive is disclosed. The HGA includes a load beam, a flexure, and a slider attached to the load beam by the flexure. The load beam comprises one or more apertures configured to pass a laser beam at each of at least three non collinear points to measure at least one slider parameter. The method for measuring at least one slider parameter includes positioning the slider over a rotating medium and projecting a laser beam through the one or more apertures in the load beam.
