Abstract: A system and method for sensing an edge of a region includes at least one distance sensor configured to detect a plurality of distances of objects along a plurality of adjacent scan lines. A controller is in communication with the at least one distance sensor and is configured to determine a location of an edge of a region within the plurality of adjacent scan lines. The controller includes a comparator module configured to compare values corresponding to the detected plurality of distances, and an identification module configured to identify the location of the edge of the region according to the compared values. In one example, the values corresponding to the detected plurality of distances include couplets of standard deviations that are analyzed and selected to identify the location of the edge.

Abstract: Methods, systems, and computer-readable media for a service for managing quantum computing resources are disclosed. A task management service receives a description of a task specified by a client. From a pool of computing resources of a provider network, the service selects a quantum computing resource for implementation of the task. The quantum computing resource comprises a plurality of quantum bits. The service causes the quantum computing resource to run a quantum algorithm associated with the task. The service receives one or more results of the quantum algorithm from the quantum computing resource.

Abstract: A folding tablet arm attachment mounted on a metal folding chair which has a ganging feature includes an elongated rectilinear tubular attachment member which has longitudinally spaced apart female keyhole openings formed in a sidewall thereof and internally reinforced for mating coupling engagement with male ganging studs mounted in cantilever position on a rectilinear siderail of the chair whereby the folding tablet arm attachment is positioned and supported on the chair. Fastening tabs carried by the attaching member and disposed in overlying engagement with the chair siderail are fastened to the siderail and releasably secure the tablet arm attachment to the chair to provide a firm working or writing surface for a person seated on the chair.
