Patent CA-2335156-A1 (CA)
Inventor: SQUARCIA STEPHANIE R
IPC: A61M5/142
Filed: 1999-06-18
Abstract: A drive connector for elastomerically coupling a drive shaft to a driven shaft.  An elastomeric coupling (42) includes openings (74, 80) on opposite ends that are . generally "D"-shaped forming an interference fit with correspondingly shaped ends of the drive shaft and the driven shaft. A web (98) extends transversely within the interior of the elastomeric coupling, limiting the distance that the drive shaft and driven shaft are inserted within the openings of the coupling. The coupling includes a rib (72) that runs longitudinally along its outer length. A sleeve (86) having a groove (90) corresponding in size and shape to the rib is slipped over the coupling and is connected to the driven shaft. The sleeve includes a rigid interior element that is overmolded with an elastomeric material. A cam bearing (48) is fitted over a cam surface (96) on the sleeve (86) and provides a force in one direction, urging a plunger (58) to displace an elastomeric membrane (20) in a pumping cassette (10), forcing medicinal fluid to flow through the pumping cassette. The elastomeric membrane provides the restoring force to the plunger, so that a loop formed on the upper portion of the plunger and disposed around the cam bearing does not receive any force from the cam bearing to move the plunger away from the pump cassette. The elastomeric coupling and sleeve form a relatively compact assembly for coupling the drive shaft to the driven shaft and accommodate minor misalignment between the center lines of the drive shaft and the driven shaft.

Title: Method of and apparatus for time synchronization in a communication system
Inventor: MOERDER KARL E
IPC: H04B7/212
Filed: 1999-07-21
Abstract: Time alignment of a signal from a remote unit (40) at a hub station (20) of a multiple access system is achieved based upon an initial time indication received from the hub station (20) at the remote unit (40) via a satellite (30). The remote unit (40) transmits a signal to the satellite (30), monitor s for a retransmission of the signal from the satellite (30) and measures the time difference between the outgoing and incoming signals. The remote unit (40), then, uses the time difference to more finely adjust the time alignmen t. Alternatively, the remote unit (40) transmits a first signal advanced with respect to an on-time estimate to the hub station (20) and receives a responsive energy indication from the hub station (20). The remote unit (40)  transmits a second signal delayed with respect to the on-time estimate to th e hub station (20) and receives a responsive energy indication from the hub station (20). The remote unit (40) compares the two energy indications and adjusts the on-time estimate. In another embodiment, the remote unit (40') receives a compensated time indication from the hub station (20'). The remot e unit (40') compares the time indication with the time at which the indicatio n was actually received based upon a local, accurate time reference. The remot e unit (40') sets atransmission timer equal to the current time indicated by the local reference advanced by the difference between the time indication a nd the time which the time indication was received.
