Other embodiments may be disclosed and/or claimed.

Abstract: Some embodiments may include at least one sensor to collect at least a portion of data driving a perception system of a working machine or driving autonomously or semi-autonomously control of actuators of the working machine; a housing defining an environmentally isolated cavity containing the at least one sensor, the housing comprising: a signal-permeable material having an interior surface and an exterior surface, the interior surface defining part of the environmentally isolated cavity; and a body to passively divert water and/or debris away from the exterior surface of the signal-permeable material, at least part the exterior surface of the signal-permeable material inset with respect to a part of the body; and one or more devices to actively generate a barrier over part of the exterior surface of the signal-permeable material, wherein the actively generated barrier repeals particulate from at least part of the exterior surface of the signal-permeable material.

Abstract: An access control system is provided to prevent the surreptitious granting of access to privacy related functionality on an electronic device. Software-based events to grant access to device functionality can be validated by confirming that the software event corresponds with a hardware input event. This validation prevents the spoofing of a user interface input that may be used to fraudulently grant access to specific functionality.

Abstract: A shooting rest, components thereof, and associated methods. The shooting rest includes a frame, a forward firearm support connected to the frame, and a rear firearm support connected to the frame. The rear firearm support includes a stop configured to limit rearward movement of the firearm with respect to the frame when the firearm is fired. A liquid tank is supported by the frame and is configured to hold liquid to increase the effective mass of the shooting rest to reduce recoil felt by a shooter when the firearm is fired.

Abstract: Provided is a technique for determining a context of an image and an object depicted by the image based on the context. A trained context classification model may determine a context of an image, and a trained object recognition model may determine an object depicted by the image based on the image and the context. Provided is also a technique for determining an object depicted within an image based on an input location of an input detected by a display screen. An object depicted within an image may be detected based on a distance in feature space between an image feature vector of an image and a feature vector of the object, and a distance in pixel-space between an input location of an input and location of the object within the image.

Abstract: Provided are mechanisms that allow selective compliance in robot joints.

Abstract: A system for monitoring at least one projectile during flight. The system includes a radar apparatus, a trigger, and a processor. The radar apparatus transmits a radar signal that includes a base radar frequency signal with a frequency shift. The radar signal has a signal profile in a direction of a chosen target and reflects off the projectile(s) traveling through the signal profile toward the target. The radar apparatus receives at least one reflected signal from the projectile(s). The trigger is operably coupled to the radar apparatus to automatically initiate operation of the radar apparatus. The processor collects data from the radar apparatus and calculates velocity of the projectile(s) based thereon. The present disclosure further provides a method of monitoring the projectile(s) during flight with the system. The present disclosure further provides a chronograph system with a housing, aiming device with a peep sight, and a trigger.
