Title: Method for causal ordering in a distributed network
Inventor: KOCH RUPPERT ROLF
IPC: G06F9/46
Filed: 1998-09-21
Abstract: A system and method for causal ordering in a distributed network with a minimum amount of delay. In a distributed network having three interconnected nodes, each having synchronized clocks, the second node sends a message to the first node. Before it sends the message, however, the second node attaches a time stamp t2 to the message. To determine when the first node can provide a causally ordered response, the method first determines a minimum message latency f from the third node to the second node. The method then adds the value of the time stamp t2 to the message latency f to calculate a minimum response time t1. On or after the time t1, the first node can provide the causally ordered response.

Inventor: BALDOMERO RICARDO R
IPC: B62K25/08
Filed: 1998-08-25
Abstract: An adjustable fluid damping system (24) for use in a suspension system that undergoes compression and rebound. The fluid damping system (24) permits independent adjustment of compression and rebound damping by providing separate compression and rebound damping circuits. Each circuit has an inlet (42, 52) through which damping fluid flows during damping, and an adjuster that adjusts the degree to which the inlet is open and hence damping through that flow path. The compression and adjusters are selectively and independently coupled to the same adjuster rod (92) via respective compression and rebound couplers (94, 96). The adjuster rod (92) can be coupled to only one of the couplers (94, 96) at a time. Rotation of the adjuster rod (92) by means of an adjuster knob (62), which can be pulled outward or pushed inward to engage one of the compression and rebound couplers (94, 96), causes rotation of the coupler coupled thereto and axial movement of the respective adjuster to modify damping though the associated damping circuit.
