Abstract: This disclosure relates to a system that generates data describing physical surroundings of vehicles during operation. Individual vehicles carry sensors configured to generate output signals conveying information related to one or both of the physical surroundings of the vehicles and/or the operation of the vehicles. Based on the generated output signals, the physical surroundings in which the first vehicle is operating are derived, such as, for example, the speeds of different nearby vehicles, and their distances to each other.

Abstract: A surgical instrument includes a body, a shaft, and an end effector. The end effector includes a staple cartridge unit having a housing and an anvil configured to form staples ejected from the housing into tissue. The end effector also includes a cartridge retaining member having an opposed pair of jaws configured to cooperate to grip the housing of the staple cartridge unit. The end effector further includes a deflectable retention member configured to removably secure the housing of the staple cartridge unit to the cartridge retaining member. The deflectable retention member is presented by one of the staple cartridge unit or the cartridge retaining member, and is configured to be deflected relative to a portion of the one of the staple cartridge unit or the cartridge retaining member from an undeflected state to a deflected state by the other of the staple cartridge unit or the cartridge retaining member.

Abstract: A presentation system capable of detecting one or more gestures and contacts on a touch sensitive display. The presentation system can displaying indicia of such contacts, such as when a user writes with a fingertip, and can remove or alter such indicia responsive to other gestures and contacts. The system can accurately distinguish between types of gestures detected, such as between a writing gesture and an erasing gesture, on both large and small touch sensitive displays, thereby obviating the need for a user to make additional selective inputs to transition from one type of gesture to another. The system can determine how long to keep user annotations displayed during a presentation, based on the nature of the gesture used to make the annotations and the context in which they are made.

Abstract: In addition to drilling operations a hard rock drill rig is used to induce seismic energy into subsurface rock formations. In quartz rich rock the seismic energy will partially convert to electrical energy thereby allowing for the prospecting of ore-bearing quartz veins. Seismic energy and electric energy are detected by a sensor array. The electric energy is used to infer the presence of piezoelectric materials in the rock formations, and such materials are mapped using the detected seismic energy and electric energy.
