Abstract: Autonomous vehicle methods and systems are described herein for communicating with an autonomous or semi-autonomous vehicle to remotely control operation of the vehicle, to detect and remove unauthorized passengers, to deliver loads, to receive registration information for the vehicle, to provide accessibility information to the vehicle, and/or to receive sensor or other environmental data to integrate with an electronic game or other extended reality experience.

Abstract: Methods and systems for obtaining vehicle recall notifications are described herein. A vehicle having one or more autonomous operation features may receive a notification indicating that the vehicle requires a safety recall. The notification may provide identification information for a vehicle part that needs to be replaced. Additionally, the vehicle may determine whether the vehicle part is currently within the vehicle by obtaining a set of identification information for current vehicle parts within the vehicle and comparing the identification information for the vehicle part to the set of identification information for current vehicle parts within the vehicle. In response to determining that the vehicle part is currently within the vehicle, the vehicle may identify a treatment facility for replacing the vehicle part, and cause the vehicle to travel to the identified treatment facility for replacing the vehicle part.

Abstract: A method performed at an analysis server, comprising: identifying data objects used by logic configured to produce alternative outcomes depending on first values of the data objects; obfuscating the data objects to produce obfuscated data objects that are related to, but do not identify, the data objects; sending, to a target device, individual requests for second values of the obfuscated data objects; receiving, from the target device, individual responses to the individual requests, wherein the individual responses include obfuscated second values that are related to but do not identify the second values; and evaluating the logic using the obfuscated second values in place of the first values, and without de-obfuscating the obfuscated second values, to produce one of the alternative outcomes.

Abstract: A dual balance electrode trap having an outer chamber, a droplet dispenser holder removably coupled to the top surface of the outer chamber, and a rod holder having a central opening and four peripheral openings that are sized and shaped to allow four respective quadrupole metal rods to pass therethrough. The droplet dispenser holder has a top surface, a bottom surface, and a through hole that extends from the dispenser holder top surface to the droplet dispenser bottom surface. The through hole has a larger diameter portion adjacent to the top surface and a smaller diameter portion adjacent to the bottom surface, thereby preventing a droplet dispenser distal tip from extending entirely through the hole and contacting electrodes in the DBET. The rod holder is configured to be removably coupled to the quadrupole metal rods so that a location of the rod holder relative to the metal rods is adjustable.

Abstract: The present disclosure relates to optical devices and systems, specifically those related to light detection and ranging (LIDAR) systems. An example device includes a shaft defining a rotational axis. The shaft includes a first material having a first coefficient of thermal expansion. The device also includes a rotatable mirror disposed about the shaft. The rotatable mirror includes a multi-sided structure having an exterior surface and an interior surface. The multi-sided structure includes a second material having a second coefficient of thermal expansion. The second coefficient of thermal expansion is different from the first coefficient of thermal expansion.

Abstract: Example embodiments relate to LIDAR systems with multi-faceted mirrors. An example embodiment includes a LIDAR system. The system includes a multi-faceted mirror that includes a plurality of reflective facets, which rotates about a first rotational axis. The system also includes a light emitter configured to emit a light signal toward one or more regions of a scene. Further, the system includes a light detector configured to detect a reflected light signal. In addition, the system includes an optical window positioned between the multi-faceted mirror and the one or more regions of the scene such that light reflected from one or more of the reflective facets is transmitted through the optical window. The optical window is positioned such that the optical window is non-perpendicular to the direction toward which the light emitted along the optical axis is directed for all angles of the multi-faceted mirror.

Abstract: A high-power electro-optic modulator (EOM) is formed to use specialized electrodes of a material selected to have a CTE that matches the CTE of the modulator's crystal. Providing CTE matching reduces the presence of stress-induced birefringence, which is known to cause unwanted modulation of the propagating optical signal. The specialized electrodes are preferably formed of a CuW metal matrix composite having a W/Cu ratio selected to create the matching CTE value. Advantageously, the CuW-based electrodes also exhibit a thermal conductivity about an order of magnitude greater than conventional electrode material (brass, Kovar) and thus provide additional thermal stability to the EOM's performance.

Abstract: Seals used within lead bores of implantable medical devices for creating a seal to implantable medical leads inserted into the lead bores include a cylinder that engages the lead body. The length of contact of the cylinder to the lead body is at least 0.010? long while average contact pressure is no greater than (10 pounds per inch)/(contact length). Adequate electrical isolation is achieved, even when a debris particle is present between the inner cylinder and the lead body while insertion force remains acceptable.
