Abstract: Techniques are described for maintaining contextual data to support content-related actions. In an example, a system stories second content at a source. The source is associated with first content. The system sends, to a device, an object that indicates the first content. From the device at a first time, the system receives first data indicating a first request for the second content and including source information that indicates the source. From the device at a second time, the system receives second data indicating a second request for the second content, the second data including the source information, the first data and the second data received at a frequency indicated by the object. The system determines that the requests are associated with the first content based on the source information included in the received data, and stores third data indicating a presentation of the first content by the device.

Abstract: An object recognition determination produced by a perception system from data received from a ranging sensor system can be verified. A certificate can be produced that includes data for points of readings from the ranging sensor system. The points can have been segmented, by the perception system, into point sets that correspond to objects in an environment of a cyber-physical system. The certificate can also include lists of pairs of points in a point set and a velocity of the point set. A test of information in the certificate can be performed. Based on a result of the test: a rectification can be made to the perception system or the ranging sensor system or a communication can be transmitted to a control signal production module configured to produce, in response to the communication, a control signal to be transmitted to an actuator system configured to control the cyber-physical system.

Abstract: A dental tool includes: a hand piece; an endodontic hand file; a stopper, wherein the stopper comprises a first hole for receiving a portion of the endodontic hand file; and a mechanical motion module that imparts mechanical motion to the endodontic hand file. A dental system includes: a hand piece; an endodontic file; and a stopper comprising at least two holes, wherein a first hole receives a portion of the endodontic file, and wherein a second hole receives a portion of a first tube for delivering a liquid to the endodontic file. The dental system can further include a second tube partially contained in a third hole of the stopper for suctioning liquids from a patient's mouth. The dental system can also further include a mechanical motion module.

Abstract: An optical imaging system including a laser alignment system for targeting and aligning optical imaging operations. The system includes a laser configured to project two intersecting lines along an axis that inersects the optical imager at the optimal imaging distance. The lines preferably extend perpendicularly to each other and are dimensioned to correspond to the length and width of the target when the optical imager is at an optical distance from the target. A user may properly align the optical imager by viewing the lines projected onto the target and adjusting the optic imager accordingly to quickly and easily ensure proper imaging of the target.
