IPC: H04L1/18
Filed: 1998-11-03
Granted: 2012-03-20
Abstract: In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.

Abstract: A method of obtaining superabrasive grinding performance from tools employing less expensive, non-superabrasive conventional abrasive grain involves operating the conventional abrasive tool at ultra high tangential contact speed, (that is at least about 125 m/s). Such ultra high operating speeds can be achieved with segmental abrasive grinding wheels having segments formed from vitreous or resin bonded particles of aluminum oxide, silicon oxide, iron oxide, molybdenum oxide, vanadium oxide, tungsten carbide, silicon carbide and the like. The abrasive segments can be cemented to the con of the tool with an adhesive such as epoxy cement. Abrasive segments can be made to a significantly greater depth than traditional superabrasive-bearing segments, and consequently, should provide long life as well as high performance. Additionally, conventional abrasive segments are easier to true and dress and to make into intricate profiles for grinding complex shaped work pieces.

Granted: 2008-11-25
Abstract: An inflation device (5) for an inflatable article (such a life jacket), includes a housing (8) for holding a container of pressurised fluid (6), a displacement means (12) including a piercing means (15) displaceable so as to penetrate the container (6) and allow the release of said pressurised fluid, and actuation means (23, 27, 28, 29) having engaging co-operating elements (17, 25) which engage to retain the displacement means (12) in an unactuated configuration. The actuation means (23, 27, 28, 29) release the displacement means (12) both through the presence of water or by manual operation. The co-operating elements (17, 25) are substantially radially arranged. The line along which the displacement means (12) acts may be coaxial with the radii of the co-operating elements (17, 25). One of the co-operating elements (17) is capable of inward radial movement, and the actuation means (27, 28, 29) operates to prevent that co-operating element's (17) radially inward movement. Similarly, one of the co-operating elements (25) is capable of outward radial movement, and also prevented by the actuating means (23). When the actuation means (23, 27, 28, 29) is triggered (by water or by the manual release), the movement of one of the co-operating elements (17, 25) causes the displacement means (12, 15) to pierce the container.

Granted: 2009-05-12
Abstract: A vehicle monitoring and notification system (42) includes a route handler (52), a schedule monitor (56), and a communication handler (92). The schedule monitor (56) determines when users should receive notification messages based on data that indicates when vehicles are expected to arrive at certain locations. The route handler (52) communicates with vehicle control units (61) on board vehicles to determine whether and how much any of the vehicles are off schedule. If any of the vehicles are off schedule, the route handler (52) updates the data monitor by the schedule monitor (56) to change when the schedule monitor (56) determines that notification messages should be received by the users. Once the schedule monitor (56) determines that a user should receive a notification message, the schedule monitor (56) transmits a notification request to the communication handler (92). The communication handler (92) then establishes communication with a communication device (99) associated with the user and transmits a notification message to the user.  Therefore, the user is warned of an impending arrival of a vehicle at a particular location.
