Abstract: An autonomous vehicle includes a detection system for identifying the presence of authorities or emergency vehicles on a road, such as law enforcement vehicles, fire engines, fire trucks, police officers, first responders, traffic cones, flares, etc. The detection system may include audio and visual detection system dedicated to the detection of authorities. Additionally, systems that correlate the detected authorities and/or any audible or visual instructions given by the authorities to changes in the behavior of the autonomous vehicle. The autonomous vehicle may react to the detected authorities or emergency vehicles by determining a driving related operation to safely operate around the detected authorities or emergency vehicles.

Abstract: Systems, methods, and devices are disclosed for surgical instruments, systems, and methods for preventing skiving of a drilling instrument during a robotic or robot-assisted surgery are disclosed. In one embodiment, a scan of a patient's anatomy can be performed to produce a model of the bone to be drilled into and analysis of the surface can determine if the curvature is such that, if a target trajectory for a bore were followed, skiving of the drilling instrument is likely. If so, an alternate anti-skiving trajectory can be determined. The anti-skiving trajectory of a bore differs from the target trajectory by at least one of entry point, diameter, axis, or depth.

Abstract: The techniques described herein relate to methods and apparatus for firearm safety mechanisms, visual safety indicators, and related techniques. A firearm includes a handle comprising one or more buttons disposed at least partially within a surface of the handle, such that the one or more buttons can be in contact with an operator's hand when the operator grasps the handle; a safety mechanism in mechanical communication with the trigger. The safety mechanism comprises: a first position that blocks actuation of the trigger; and a second position that does not block actuation of the trigger; and at least one processor configured to: upon determining an input code matches a stored code, transmits a signal to the safety mechanism to change the safety mechanism from the first position to the second position so that the firearm can be fired by the operator.

Abstract: A lens assembly for systems such as imaging devices. The lens assembly may include at least five lens elements, where one or more of the lens elements includes positive optical power and one or more of the lenses includes negative optical power. The lens assembly may further include an aperture stop located between the lens elements. In some instances, the lens assembly provides a horizontal field of view that is at least 80 degrees while still including a total track length that is less than or equal to 50 millimeters and a diameter that is less than or equal to 13 millimeters. Additionally, in some instances, the lens assembly may cause all rays which impinge the sensor to be less than or equal to approximately 10 degrees.

Abstract: Methods are provided in which a recording service obtains a multimedia stream along with metadata of an established collaboration session in which at least two participants collaborate via respective user devices. The recording service identifies each of the at least two participants of the established collaboration session based on the metadata and obtains an individual recording privacy control associated with each of the at least two participants based on identifying. The recording service further generates a recording of the established collaboration session restricted by the individual recording privacy control for each of the at least two participants.

Abstract: An online agricultural system manages and optimizes interactions of entities within the system to enable the execution of transaction and the transportation of crop products. The online agricultural system accesses historic and environmental data describing factors that may impact crop product transactions and/or transportation to determine market prices for crop products and crop product transportation. Responsive to receiving a request from an entity, the online agricultural system determines an optimal transaction for the entity, such as a price for selling a crop product, an available crop product for purchase, or a transportation opportunity to transport a crop product.

Abstract: An autonomous vehicle (AV) includes features that allows the AV to comply with applicable regulations and statues for safe operation. An AV may operate in conjunction with an oversight system, such as when coordinating a fleet of autonomous vehicles. One aim of AV technologies is to provide vehicles that can safely navigate towards a destination with limited or no driver assistance. AVs or other types of vehicles carrying goods may be subject to theft and other undesired disturbances. Systems, apparatus, and methods are provided to ensure a chain of custody for cargoes in an AV. Numbered seals are attached to the doors of an AV to detect unauthorized door open operations. Unauthorized vehicle stops are also detected based on position tracking information of the AV. Changes in cargo weight can also be detected.

Abstract: A weight balancing system for a vehicle performs a method of adjusting a weight on a wheel of a vehicle. The system includes a processor of the vehicle and a scale. A wheel of the vehicle is placed on the scale, the wheel having an associated spring seat and associated spring. The scale measures a weight placed on the wheel by the vehicle and communicates the weight to the processor. The processor activates the spring seat to adjust a length of the spring, thereby adjusting the weight placed on the wheel by the vehicle.
