Abstract: An indexed sequence of bits in a buffer is allocated for tracking a battery charging state. The indexed sequence of bits has a first number of bits. A battery voltage of a rechargeable battery is sampled at a sampling rate. For each sampled battery voltage, the battery voltage is compared with a voltage threshold. A next bit position in the indexed sequence of bits is identified. In accordance with a determination that a comparison result is true, a predefined first value is added to the next bit position. A second number of bits that are filled with the predefined first value is determined. A ratio between the second number and the first number is also determined. In accordance with a determination that the ratio exceeds a threshold step-down ratio, a battery charge voltage is stepped down. The rechargeable battery is charged to a step-down voltage.

Abstract: A local computing device of a vehicle receives a stream of sensor data from one or sensors of the vehicle. If a remote computing device is estimated to process the stream of sensor data and provide driving instructions within a maximum acceptable wait time, then the local computing device sends a request to the remote computing device to process the stream of sensor data and provide driving instructions. If the processing is estimated to meet or exceed the maximum acceptable wait time, then the local computing device uses a locally executed neural network to determine driving instructions. The driving instructions received either from the remote computing or from the local neural network are sent to an autonomous driving system of the vehicle. Offloading processing the sensor data to the remote computing device may result in the local computing device consuming less energy.

Abstract: The present document describes methods and systems for battery authentication. In aspects, the battery includes an identifier (ID) resistor integrated into the battery label and having at least one exposed resistor contact. The location of the resistor contact can be used for mechanical keying for identification of the battery. The ID resistor has a resistance value that corresponds to a type of the battery. To detect the ID resistor, a device can have electrical contacts (e.g., pogo pins) that are exposed in a battery housing and that electrically connect to the resistor contact(s) of the battery. The device can use a lookup table to identify the type of the battery based on the resistance value of the ID resistor. Such identification of the type of the battery enables authentication of the battery to the device and initiation of one or more functions based on whether the battery is valid.

Abstract: Various examples are directed to systems and methods for directing a field-of-view of a first sensor positioned on an autonomous vehicle. In one example, at least one processor selects a goal location on at least one travel way in an environment of the autonomous vehicle. The selecting of the goal location is based at least in part on map data describing at least one travel way in an environment of the autonomous vehicle and pose data describing a position of the autonomous vehicle in the environment. The at least one processor determines a field-of-view position to direct the first sensor towards the goal location based at least in part on the sensor position data. The at least one processor sends a field-of-view command to the first sensor. The field-of-view command modifies the field-of-view of the first sensor based on the field-of-view position.

Abstract: The present document describes techniques for extending battery life after long-term and high-temperature storage. These techniques delay charging of a battery to detect battery conditions and determine whether the battery was exposed to high temperatures while in an idle or low-power state for a long period of time. These techniques include a methodology to relax and refresh an anode surface of the battery, after high-temperature storage, through distinct and tailored discharges prior to beginning a normal charge profile. These techniques can be applied to a wide range of chemistry platforms, which may have kinetic (Li-ion) limitations, to extend the longevity of the battery by reducing lithium plating and capacity degradation caused by long-term, high-temperature storage.
