Abstract: A combination of parametric and non-parametric approaches are disclosed for enabling pilot-based SINR estimation, for MIMO systems. The pilot-based SINR estimation embodiments account for preceding applied during either single-stream or multi-stream data transmission. The pilot-based SINR estimation embodiments also account for code reuse interference which arises during multi-stream data transmission when spreading codes are reused on the data channel. Accordingly, mismatches that exist between the data channel and the pilot channel because of preceding and/or code reuse are inherently accounted for by the pilot-based SINR estimation, embodiments disclosed herein.
Patent CA-2770634-A1 (CA)
Inventor: BARMATOV EVGENY
IPC: E21B43/26
Filed: 2010-08-05
Abstract: Solid material required at a subterranean location is supplied from the surface suspended in a carrier liquid and agglomerated below ground by means of a binding liquid. Agglomeration is achieved by arranging that the binding liquid and the particulate solid are similar to each other but opposite to the carrier liquid in hydrophilic/hydrophobic character. The solid and the binding liquid may both be hydrophobic while the carrier liquid is hydrophilic, or vice versa. The solid may be hydrophobically surface modified to render it hydrophobic. The binding liquid may be provided as a precursor which converts to the binding liquid below ground to trigger agglomeration after arrival at the subterranean location. The agglomerates may function as proppant heterogeneously placed in a fracture of a reservoir, or may serve to block an unwanted path of flow. The binding liquid may polymerise after agglomeration so as to stabilise and strengthen the agglomerates.

Patent CA-2787158-A1 (CA)
Inventor: LAMBERT DALE J
IPC: G01V1/36
Filed: 2011-01-19
Abstract: A system and a method for rejecting noise in an underwater sensor cable, such as a towed streamer or an ocean-bottom cable. An adaptive hydrodynamic model of the cable produces an estimated sensor signal from a raw sensor signal from a particle-motion sensor, such as an accelerometer. The estimated sensor signal represents an estimate of the response of the underwater cable to cable motion absent seismic events. A noise-reduced response to particle motion alone is produced by subtracting the estimated sensor signal from the raw sensor signal to reject cable motion and other noise effects in the raw sensor signal. A seismic event detector uses a hydrophone signal from an acceleration-canceling hydrophone to disable the adapting of the hydrodynamic model during seismic events. The hydrophone signal is combined with the response to particle motion by PZ summation to produce a deghosted seismic response signal.

Title: Systems and methods for harvesting, storing, and implanting hair grafts
Inventor: OOSTMAN CLIFFORD A JR
IPC: A61F2/10
Filed: 2008-08-21
Abstract: A system and method for harvesting, storing, and implanting biological units, in particular hair follicular units (FUs). The system is particularly useful to facilitate hair transplant procedures.  FUs are harvested from a body surface, either attached to a patient or in a strip of removed tissue, and shuttled into a cartridge having a plurality of receptacles. The receptacles are open in a distal direction toward a removal tool, but a cover over the proximal ends of the receptacles prevents the FUs from continuing out of the cartridge. The cover is made of a permissible medium, which may be fluid permeable and/or puncturable. One way to shuttle the FUs is to provide a pressure differential, such as by applying suction to the proximal end of a receptacle.  The shuttle subsystem may be incorporated within an overall automated or robotic system, or the shuttle subsystem may form part of a semi-automated or even manual apparatus.
