Title: Convertible skateboard/scooter
Inventor: OGIE SAMUEL
IPC: A63C17/26
Filed: 2000-02-23
Abstract: The convertible skateboard/scooter of the invention includes a base board with wheels coupled to a lower side of the base board. A handle is hinged to the base board and is movable between a first position in which the device can be used as a conventional skateboard, and a second position in which the device can be used as a conventional scooter. In the skateboard configuration, the handle is located adjacent a side surface of the device to provide a top surface that is unobstructed by the handle and upon which a user can stand while skateboarding. A parental lock can be located in the handle to lock the handle at either one of the first and second positions and to prevent the conversion of the device between the skateboard and scooter configurations by a child. An indent in the rear of the base permits the handle to be used for carrying the device when in the skateboard configuration.

Filed: 1997-11-03
Abstract: A drive assembly (22) for a pulley (26) comprises a first pulley (26) having a cable (20) passing around part of the pulley circumference. Three relatively small pulleys (30, 32, 34) are mounted on the assembly body (24) and a belt (36) extends around the pulleys. The belt (36) is driven and two of the small pulleys (30, 34) are located on a chord of the first pulley (26) such that tension in the belt (36) tends to bias the belt (36) to bear against the cable (20) as it passes around a portion of the circumference of the first pulley (26) located between the two small pulleys (30, 34).      In a further embodiment, a convex support surface (70; 86) is formed by a belt (62) or rollers (92), rather than by the pulley (26).      In another embodiment an assembly (150) may be used to drive a ground engaging wheel (164) of an aircraft or vehicle, rather than a pulley wheel (26).

Abstract: A disk-like piezoelectric crystal element having an axis of maximum strain sensitivity has a pair of electrodes sputter deposited on opposite faces. A pair of annular resilient spacers are disposed one over each electrode on the piezoelectric element and a cover is disposed over each spacer to form an air gap respectively between the cover and the electrode and forms a transducer subassembly. A torsion member to be subjected to an applied torque has an area prepared, preferably recessed and the subassembly disposed in the recess with the axis of maximum strain sensitivity oriented at about 45° to the torque axis. The subassembly has electrical leads attached and is potted in the recess with strain transmitting potting compound such as epoxy. The electrical leads are coupled to an external oscillator circuit via a rotary variable capacitive coupling.

Patent CA-2351192-A1 (CA)
Title: Fault-tolerant networking
Inventor: LI LING
IPC: H04L69/40
Filed: 1999-10-07
Abstract: Methods and apparatus for implementation of fault-tolerant networks provide a network fault-tolerance manager for detecting failures and manipulating a node to communicate with an active channel. Failure detection incorporates one or more methods, including message pair and link pulse detection. Failure recovery includes switching all node data communications to a stand-by channel or switching just those nodes detecting a failure. Communication between nodes provides the distributed detection, with detecting nodes reporting failures to their network fault-tolerance manager and the network fault-tolerance manager broadcasting the failure recovery to all nodes. The network fault-tolerance manager is middleware, residing with each node in a logical hierarchy above a physical layer of a network and below a transport layer of the network. The approach is particularly suited to Ethernet LANs and capable of using commercial off-the-shelf network components.
