Abstract: Aspects of the present disclosure are directed to establishing a shared anchor object and common coordinate system amongst multiple extended reality (XR) systems accessing a multiuser XR environment. Virtual objects (including avatars of users accessing the multiuser XR environment via respective XR systems) can be consistently mapped in the XR environment relative to the anchor object. The anchor object can be a virtual object, such as a menu or shape (e.g., a ring), or a physical object, such as a stage computing device positioned in the users' surrounding real-world environments. The users can move the anchor object as rendered on their respective XR systems, which can cause reciprocal movement of their corresponding avatars on other users' XR systems. The users can further move virtual objects relative to the anchor object, which can cause similar movement relative to the anchor object in the XR environment as rendered on the accessing XR systems.

Abstract: An elongate shaft of a medical catheter including a thermoset polymeric tubular member including a skived distal portion. The skived distal portion includes a distally extending trough having a convex surface and a concave surface. A thermoplastic tubular sleeve may be positioned over at least a portion of the skived distal portion of the thermoset polymeric tubular member. In some instances, the thermoplastic tubular sleeve includes a crescent-shaped tubular portion defining a crescent-shaped lumen. The trough of the skived distal portion may extend through the crescent-shaped lumen. The thermoplastic tubular sleeve is thermally bonded to the inner and outer tubular members of a distal section of the elongate shaft at a guidewire port joint.

Abstract: The system supports special needs customer at an airport. A controller processes request, flight and personnel data, generates assignments, and distributes messages. Workstations register available personnel, import/export customer requests and flight information, edit additional customer and flight data, and authorize or overwrite dispatch decisions. Handheld devices provide customer registration, service recording and location registration, and communicate service instructions and activity planning. The controller receives and analyzes data based upon a set of conditions that determine the status of any service request, the location where service is needed, the type of assistance needed, its priority, and the destination of the service. Upon arrival at the destination, or, based upon a set of predetermined conditions, the controller analyzes current conditions, determines the next set of requests and assignments, and provides information needed to support the next assignments.

Abstract: A solid state crossing controller for a railroad crossing signal system with two independent outputs for controlling illumination of lamps in the signal system share a common neutral or return wire, with sensing of a common neutral or return line shared by the two independent outputs to determine any loss of the neutral line. When a failure has been detected in the neutral line, the controller modifies the voltages for the lamps in the signaling system for better illumination of the lamps during the failure condition, such as to the highest voltage available from a battery in the system. Upon detection of the failure in the neutral line, the controller may provide a call or message that there is a failure in the system that is in need of repair. If the failure in the neutral line is intermittent, the controller will resume normal operation after that train, has cleared the crossing. However, a call or message that a failure has occurred in the neutral line is provided.
