Abstract: Systems and methods for providing a mobility service are described. A method for providing a mobility service includes receiving a request from a user. The request includes a mobility device to assist the user and at least one logistical factor. Logistical factors may include timing, an origin, or a destination. The method also includes scheduling the mobility device and a companion vehicle for the user based, at least in part on, the at least one logistical factor. The companion vehicle provides the user transportation on at least a portion of a route between the origin and the destination. The method also includes generating data based on providing the user transportation. The generated data includes one or more of request data associated with the request, user data associated with the progress of the user on the route, mobility device data associated with the mobility device, and companion vehicle data associated with the companion vehicle.

Abstract: A particleboard web member interconnects a pair of wood chord members by means of glued tongue and groove joints to form an I-beam or roof truss. A pair of grooves in each chord member receives a pair of parallel tongues on the web member. The grooves are inclined from top to bottom to bend the tongues out of parallelism and form self-locking dovetail-type joints which hold the members together in assembled relation without the use of external clamps while the glue is setting.

Abstract: The leading ends of a tongued web member and a pair of grooved chord members are moved longitudinally against stops, with the trailing ends of the chord members spread apart in divergent relation. A pair of opposed pistons presses the leading ends of the chord members toward the opposite side edges of the web member, forcing the tongues on the web member into the grooves of the chord members, which grooves have previously been coated with glue. Then the stops and pistons are retracted and the three members, thus joined together at their leading ends, are advanced between a pair of rubber tired drive wheels, meanwhile allowing the divergent trailing ends of the chord members to swing toward each other as the members progress through the drive wheels. The drive wheels are power driven to feed the assembled beam through sizing rollers which progressively squeeze the chord members toward each other as may be necessary to produce a beam of predetermined width dimension.

Abstract: Plywood web members interconnect a pair of chord members by means of glued tongue and groove joints. There are two layers of said web members in face to face relation wherein tongues on the adjacent face veneers occupy a common intermediate groove in each chord member. Tongues on the outer face veneers are bent outward by splayed outer grooves in each chord member to form a self-locking dovetail type joint which holds the members together in assembled relation without external clamps while the glue is setting.

Abstract: The joint comprises a pair of parallel tongues of uniform thickness on an edge of one member which are pressed into grooves of uniform width in another member. The grooves are inclined from top to bottom relative to each other, bending the tongues out of parallelism and thereby locking them in the grooves to form a self-locking joint equivalent to a dovetail joint. Such tongues on the top and bottom edges of a vertical member are pressed into longitudinal grooves in elongated top and bottom chord members to form an I-beam or truss section. The tongues may be formed on the edge of a board or they may comprise the opposite face sheets on a plywood panel. Also, the joint members may be metal.

Abstract: A truss to be tested is laid on its side on a table having an upstanding flange along one side. A load cell is interposed between one end of the bottom chord of the truss and the table flange and a block is interposed between the opposite end of the bottom chord and the table flange. A flattened flexible tube is disposed on edge along a similar flange on the opposite side of the table. Blocks are inserted between the flexible tube and the top chord of the truss to simulate a uniform snow load when the tube is inflated. One-half the total load is measured directly by the load cell and the deflection of the center of the bottom chord is measured by a scale on the table. If the deflection remains within an allowable amount so as not to close a limit switch within a prescribed loading interval, a timer actuates a rubber stamp to mark the truss as having passed the test.
