Abstract: In one embodiment, a safety system for playing vehicle monitored content in a vehicle while minimizing driver distraction is provided. When the driver selects a camera, such as a rear view camera, vehicle monitored content stream from the camera is displayed on a display in the vehicle. While the driver drives the vehicle, the eye-gaze of the driver is monitored. When the eye-gaze of the driver shows that the driver is looking at the display, a timer is started. The timer runs when the driver looks at the display. When the eye-gaze of the driver shows that the driver has looked at the road continuously for more than a threshold amount of time, the time associated with the vehicle monitored content is reset back to its initial value. If the timer runs out, indicating that the driver has been watching the vehicle monitored content too much without also looking at the road, the vehicle monitored content is stopped and the driver is prevented from watching the vehicle monitored content for some period of time.

Abstract: System, methods, and other embodiments described herein relate to improving observations of a surrounding environment using a light detection and ranging (LiDAR) device in the presence of highly reflective surfaces. In one embodiment, a method includes, in response to determining that a first point cloud includes an observation of an obscuring object that is highly reflective: i) emitting a scanning light beam at a scanning intensity that is different from an initial intensity of an initial light beam used to acquire the first point cloud, and ii) dynamically controlling the LiDAR device to acquire a second point cloud that omits the obscuring object. The method includes generating a composite point cloud from the first point cloud and the second point cloud that improves an observation of the surrounding environment using the LiDAR device by mitigating interference from the obscuring object.

Abstract: A sparse acoustic absorber includes a periodic array of spaced apart unit cells, generally having a lateral fill factor less than 0.5. Each unit cell includes a pair of joined, and inverted, Helmholtz resonators, having neck portions that point in opposite directions. This structure enables ambient fluid, such as air, to pass through the absorber. The absorber predominantly absorbs acoustic waves having a resonant frequency when such waves are incident on the absorber in one direction, and predominantly reflect such waves when they are incident on the absorber in the opposite direction. Dual-function sound suppression systems incorporate such an absorber into a porous substrate, such as a wire mesh, that enables fluid to pass and alternatively absorbs or reflects sound.

Abstract: The present disclosure relates to generating reference signals for distance and directional elements in power systems. For example, an intelligent electronic device (IED) may receive A-phase, B-phase, and C-phase electrical measurements of a power system. The IED may transform the A-phase, B-phase, and C-phase measurements to a d-component, a q-component, and a 0-component. The IED may include an adaptive notch filter that reduces or eliminates a double frequency component that may be present when step changes of frequency and/or amplitude occur and/or when the A-phase, B-phase, and C-phase measurements have different amplitudes. By reducing the double frequency component, the IED may generate a more accurate ? which may allow for more accurately tracking changes to the polarizing source. Further, the IED may separately add inertia to the estimated angular frequency used in generating a reference signal.

Abstract: A portable lifting jack has a drivable mechanism operating a jack shaft formed of telescoping lifting screws. A microprocessor controls power to selectively turn electric motor to drive the operating mechanism. An in-line current draw sensor senses electric load of the motor and communicates this to the microprocessor.

A potentiometer connected to the operating mechanism senses extended position of the telescoping lifting screws and communicates this position to the microprocessor, which is programmed to derive when snug contact is achieved with an encountered mechanical load and to pause operation of the electric motor. In a synchronized array of jacks, all are paused to await further operator input, which may be coordinated through a remote control.

Abstract: A generator system includes a generator including terminals, a generator circuit breaker coupled to the terminals and that couples and decouples the generator from a power grid, multiple sensors, and a controller that operates the generator system. The controller determines whether an active power is less than a reverse active power threshold and whether one or more turbine valves are closed, and determines that a breaker failure has occurred based on the active power being less than the reverse active power threshold and the one or more turbine valves being closed. If the active power remains less than the reverse active power and the turbine valves remain closed after a threshold time period after the trip command, and if a reactive power is less than a reverse reactive power threshold, then a breaker failure has occurred. In response, the controller may transmit another trip command to the generator circuit breaker to initiate the breaker failure protection.
