Abstract: An actively Q-switched laser induced breakdown spectroscopy (LIBS) probe, utilizing an optical fiber, a pump beam transmitted through the optical fiber, a coupler, and a lens for collimating the pump beam. The actively Q-switched laser, coupled to a sensor which provides information to a computer that controls a high voltage pulser providing a pulse to a Pockels cell located within the laser which can selectively cause the laser to pulse, resulting in high energy pulses and a second lens for focusing the output pulse such that it creates a plasma or spark. The light from the spark is captured and directed back through an optical system to remote equipment for elemental and/or molecular analysis.

Abstract: A system and method for recovering application authentication with an application server by using an exponential back-off procedure via push notifications is discussed herein. The system allows for authentication of a user account after network outages or service disruptions without traffic overload during recovery. A user equipment (UE) receives a failed registration notification after a failed registration attempt of the user account with an application server associated with the application. A push notification includes an instruction that causes the application to switch from an inactive state to a temporary active state. The push notification is sent from a push notification service in response to a push request from a notification server based on a recovery request from the UE due to the failed registration notification. While the application is in the temporary active state, the instruction further causes the application to request registration with the application server.

Abstract: To substantially eliminate torsional freeplay in a robotic tool changer having a ball-lock coupling mechanism, scallop-like features in the form of cross-contact recesses are formed in at least one of, and preferably both of, a bearing race in a tool assembly at the points of contact of rolling members, and in the opposing inner surfaces of bores containing the rolling members in a master assembly. The cross-contact recesses are sized and shaped to receive a rolling member, but have a central void, or channel, perpendicular to the rolling member's motion in torsional freeplay, which does not contact the rolling member. The cross-contact recess contacts the rolling member at contact areas on either side of the central void.
