Patent CA-2612318-A1 (CA)
Inventor: SAMPATH HEMANTH
IPC: H04J99/00
Filed: 2006-06-13
Abstract: Techniques for performing rank prediction in a MIMO system are described. Performance metrics for a plurality of ranks are initially determined. Each rank is indicative of a different number of data streams to send simultaneously via a MIMO channel. The performance metrics may relate to the capacity or signal quality of the MIMO channel or the throughput of data transmission sent via the MIMO channel. Adjustments are applied to the performance metrics for the ranks to obtain adjusted performance metrics. Th e adjustments account for system losses such as losses due to an error correction code used for data transmission, channel estimation errors at a receiver, variation in interference observed by the receiver, variability in transmit power due to power control, and/or other factors. A rank is selecte d for use based on the adjusted performance metrics for the ranks.

Inventor: JACKSON ROGER P
IPC: A61F2/44
Filed: 2006-10-05
Abstract: A spinal fixation device combines an anchor member with an open receiver, such as a polyaxial bone screw or a hook, with a rotatable closure that operably clamps a spinal fixation rod to the anchor member. The anchor member has spaced apart arms forming a rod receiving channel . The arms have arm extensions or tabs connected to main portions of the arms by weakened regions to enable the extensions to be broken off or separated after the rod is clamped. The closure and inner surfaces of the arms and tabs have mating helical, anti-splay, reverse angle guide and advancement structure formed thereon that mechanically cooperate to prevent splaying of the arms and the extensions as the closure is advanced into the rod receiving channel . " The ' increased length of the arms with the extensions enables the rod to be captured at a greater distance from the seat of the channel and allows the rod to be urged toward the seat by helical advancement of the closure into the channel, starting between the extensions. Separation of the break-off extensions results in an implant with a desirable low profile.
