  • Publication number: 20240087738
    Abstract: A telepresence robot may include a drive system, a control system, an imaging system, and a mapping module. The mapping module may access a plan view map of an area and tags associated with the area. In various embodiments, each tag may include tag coordinates and tag information, which may include a tag annotation. A tag identification system may identify tags within a predetermined range of the current position and the control system may execute an action based on an identified tag whose tag information comprises a telepresence robot action modifier. The telepresence robot may rotate an upper portion independent from a lower portion. A remote terminal may allow an operator to control the telepresence robot using any combination of control methods, including by selecting a destination in a live video feed, by selecting a destination on a plan view map, or by using a joystick or other peripheral device.

  • Publication number: 20220383256
    Abstract: The disclosure herein describes systems and methods for generating a post-vehicular incident report. In some examples, the system includes receiving a notification from a user device indicating the user device has been involved in an incident, obtaining incident data from the user device that includes a timestamp and location data, retrieving third-party incident data corresponding to the timestamp and the location data received in the incident data, generating a timeline of the incident based on the obtained incident data from the user device and the retrieved third-party incident data, the generated timeline including events occurring prior to the incident and events occurring after the incident, generating a report of the incident based on the generated timeline, the obtained incident data, and the retrieved third-party incident data, the report including the timeline, and outputting the generated report to the user device and at least one of a plurality of approved devices.

  • Publication number: 20060020102
    Abstract: This invention relates to a resin composition capable of being thermally cured while minimizing or eliminating voids in the resulting composite, the composition having both a long pot life at low temperatures and a fast curing rate at higher temperatures containing a mixture of (a) a phenol-formaldehyde resole resin, and (b) an etherified hardener, the etherified hardener being prepared from an alkoxylated polyol or a mono epoxy functional diluent.

  • Patent number: 6643448
    Abstract: A method and apparatus is described for stripping the coating of an optical fiber. A fixture having a fiber cleat may be used to secure an optical fiber to enable removal of the protective coating from the fiber along a precise length of the fiber. The length of protective coating removal may be controlled by a strip guide. A stop coupled to the apparatus also controls how much of the coating is removed.
