Abstract: A computer readable media, a method, and a system registering a third party application providing an available communication system between a local user and a remote user identity, storing information related to the available communication system in a first database, obtaining contact information for the remote user identity from the third party application, determining a communication type for the third party application, pairing the remote user identity with a contact, and updating a graphical representation of contact information.

Abstract: An amusement device comprises six rigid bodies permanently connected via six pivots in a closed loop, each body containing a track segment or track segments bearing game pieces movable in the track segments. Axes of the pivots form a symmetrical pattern around a line of symmetry, and as a consequence, the pivots allow the rigid bodies to be reoriented by a player, so as to align different track segments end to end. Game pieces can then be moved from one track segment to another. The object of play is to arrange game pieces in a specific pattern among the six bodies.

Abstract: A mobile aerial device, which also has deployable outriggers, has sensors for the outrigger-supported weight, sensors for boom azimuth, elevation and extension, and sensors for other boom conditions. An on-board digital computer is programmed with load tables for the device. The various sensor signals and load table data are computer-processed to determine the approach of tipping or overload conditions. When operating near a dangerous obstacle which it is desired to avoid, the boom is initially caused to assume certain preparatory positions relative to the obstacle and data are computer-generated which extrapolate from these positions a region in space which represents a prohibitively close approach of the boom to the obstacle. The foregoing information is used to alert the operator to the approach of a dangerous condition and also to prevent the crane from performing movements which could cause tipping or which would encroach upon the prohibited region.

Abstract: A non-rigid bone fracture fixator comprising first and second bone pins for connection either side of a bone fracture and primary and secondary supports clamped to the bone pins by respective fixed and guide clamps. The second support and the guide clamps are connected slidably to the primary support such that the supports may execute a controlled degree of movement with respect to one another. A compression spring is arranged to bias apart the supports longitudinally of a fixated limb. In use the fixator is applied to the limb with the fracture in slight compression. Exercise of the limb then produces varying degrees of fracture compression stimulating bone callus formation and rapid healing. The fixator may include actuating means to provide passive fracture exercise for immobilized patients.

Abstract: A post-fracture bone immobilization splint for unilateral fixation comprises a rigid bar on which are slidably mounted at least four pin clamps. Each pin clamp is fixable to the bar and is provided with a pin to engage a part of the fractured bone. The pin is supported in two holes diametrically located in a hollow cylindrical portion of the pin clamp, the diameter of the holes being larger than the pin diameter such that the pin can be adjusted slidingly as well as azimuthally within a limited range of zenith angles. The annular gap surrounding the pin is sealed by surrounding moveable washers which are spaced apart within cylindrical portion by a plastic tube through which the pin passes. The remainder of the hollow portion is filled with small ball bearings that are compressible by a threaded plug. The pin is positioned as desired and the threaded plug is then rotated to compress the ball bearings which deform the plastic tube and thereby grip the pin.

Abstract: A reel for use upon a cylindrical support on plaster jacket bedframes incorates a ratchetless anti-reverse mechanism which is readily disengageable and which permits continuous adjustment of the position of the reel upon the bedframe. The anti-reverse mechanism comprises a close wound helical spring which has a free diameter less than the diameter of the cylindrical support. The spring is mounted on the cylindrical support and attached by one of its ends to a spool rotatably mounted on the cylindrical support.

Abstract: A power assisted wheelchair has a pair of larger ground wheels with handwheels mounted thereon and a pair of smaller castor wheels carrying motors drivably coupled therewith. The handwheels are rotatable relative to their ground wheels against a spring bias and operate the castor wheel motors on the corresponding sides of the chair through respective switch mechanisms. Variations of this arrangement are possible to suit different ground wheel configurations, the motors can be energized in increasing manner, the motors can be disconnected when the castors turn rearwardly, and the motors can drive through freewheel mechanisms.
