A test device suitable for acceleratory oblique water entry of a wedge has a frame, a water tank placed below the frame, an accelerator installed above the frame, an obliquing device connected to the frame, a wedge connected to the obliuqing device and an observation system. The frame is provided with vertical slide rails and a transverse slide rail. The accelerator mainly includes an air cylinder and an air compressor. The wedge is a flexible wedge or a rigid wedge. The observation system includes a pressure sensor, a strain sensor, a velocity sensor, an acceleration sensor and a particle image velocimetry device. The repeatability of the test process can be ensured by controlling the output pressure of the air cylinder.

A remotely actuated vehicle pedal depression apparatus includes a handheld unit operatively coupled to a distal unit. Manual compression of an actuator disposed on the handheld unit effectuates extension of an extendable member forwardly from an anterior member disposed on the distal unit. Distal unit may be positioned in a footwell of an automobile to effectuate depression of a targeted pedal while a user performs observational diagnostics on the automobile without the assistance of another person.

The present application discloses a system and method for accessing vehicle communications bus information outside the bandwidth of a limited CPU without missing critical information. The system and method for accessing vehicle communications bus information outside the bandwidth of a limited CPU generally includes a vehicle interface processor, that processor's interconnect to an application processor and the vehicle interface. The vehicle interface software that vehicle interface processor has running on it and the vehicle interface processor's connection to the vehicle may also be included.

Various implementations described herein are directed to a non-transitory computer readable medium having stored thereon computer-executable instructions which, when executed by a computer, may cause the computer to detect electrical noise corresponding to one or more engines starting or running. The computer may record a first timestamp corresponding to the engines starting or running. The computer may detect that the engines have stopped. The computer may record a second timestamp corresponding to the engines stopping. The computer may also use the first and second timestamps to determine engine runtimes.

Aspects of the present disclosure are generally related to one or more systems, methods, and devices for forecasting the likelihood of locating available parking spaces at various remote locations, and navigating a vehicle to the available parking space. In some examples, aspects of the present disclosure may utilize a variety of data sources (e.g., historical data, surveyed data, and real-time parking availability data) in order to predict the likelihood of locating the available parking space within the confines of an available hours of service (HOS) requirement of a driver of the vehicle.

A system and method preserves raw vibration data for a physical event involving a transport vehicle such as a helicopter, plane, boat, car, or truck. The event may involve unexpected mechanical stresses on the vehicle. The system and method preserves raw vibration data for parts of the transport vehicle, such as from multiple points along the drive train. The preserved raw vibration data includes data from time prior to the physical event. In an embodiment, the system and method continuously detects vibration data, and stores the most recent vibration data in a circular memory buffer. The buffer is continually updated with the most current vibration data. When an event is automatically detected or manually triggered, the most recently saved vibration data is transferred from the buffer to permanent storage, along with vibration data obtained subsequent to the event. This allows for a more thorough post-event analysis.

In one example, a method for resolving sensor conflicts in autonomous vehicles includes monitoring conditions around the autonomous vehicle by analyzing data received from a plurality of sensors, detecting a conflict in the data received from two sensors of the plurality of sensors, sending a first instruction to an auxiliary sensor of the autonomous vehicle that is not one of the plurality of sensors, wherein the first instruction instructs the auxiliary sensor to gather additional data about the conditions around the autonomous vehicle, receiving the additional data from the auxiliary sensor, and making a decision regarding operation of the autonomous vehicle, wherein the decision is based at least in part on the additional data.

A device and a method for detecting faults in an electrical system. The fault detection device includes, a first measuring unit configured to receive a first error value indicative of a fault in a subset of a plurality of components, a communication unit configured to provide information to a user interface, a second measuring unit configured to be electrically connected directly to each of at least two of the plurality of components, and a processing unit connected to and configured to control the first measuring unit, the second measuring unit, and the communication unit. The second measuring unit is configured to, based on the first error value, determine a operational status of each of the components in the subset.
