Abstract: A method of evaluating an all-solid-state battery includes preparing the all-solid-state battery. A charge level of the all-solid-state battery is adjusted to produce a first potential difference between a positive electrode and a negative electrode. The positive electrode or the negative electrode is selected as a reference electrode. After the charge level is adjusted, an operation to insert a conductive rod-shaped member into a stack portion along a direction of stack of the positive electrode and the negative electrode is performed while a second potential difference between the reference electrode and the rod-shaped member is measured. The rod-shaped member is stopped. The all-solid-state battery is evaluated based on a state of the all-solid-state battery after the rod-shaped member is stopped.
Abstract: A system for producing a depth map can include a processor and a memory. The memory can store a neural network. The neural network can include an encoding portion module, a multi-frame feature matching portion module, and a decoding portion module. The encoding portion module can include instructions that, when executed by the processor, cause the processor to encode an image to produce single-frame features. The multi-frame feature matching portion module can include instructions that, when executed by the processor, cause the processor to process the single-frame features to produce information. The decoding portion module can include instructions that, when executed by the processor, cause the processor to decode the information to produce the depth map. A first training dataset, used to train the multi-frame feature matching portion module, can be different from a second training dataset used to train the encoding portion module and the decoding portion module.

Abstract: Systems and methods are provided for variable actuation and release of a vehicle's brake hold mechanism/function. A brake hold device may be implemented as a “tuner” or controller that can connect to and override, e.g., the default functionality of an existing brake hold mechanism of a vehicle. Delays in exiting a brake hold state, repetitive actuation of an accelerator to exit a brake hold state, and other shortcomings associated with the conventional operation of brake hold mechanisms may be avoided by taking into account relevant vehicle operating conditions or environmental/road/traffic conditions.
