Title: Guard independent signal mapping
Inventor: WANG MICHAEL MAO
IPC: H04L27/26
Filed: 2007-10-23
Abstract: Systems and methodologies are described that facilitate guard bandwidth independent mapping and de-mapping of bandwidth in a wireless communication system. Broadcast signals can be created as if all bandwidth were available, and guard bandwidth can be initialized over the utilized bandwidth such to puncture the data existing in the guard bandwidth. Upon decoding the broadcast signal, size of the guard bandwidth can be predetermined or estimated allowing a center portion of the signal to be decoded without decoding the guard bandwidth. In this regard, the decoder of the signal need not find exact positions of the guard bandwidth as transforming and decoding the center portion can provide a substantial portion of the signal to interpret the signal.

Patent CA-2676273-A1 (CA)
Title: Leach recovery of minerals from composite carbonate/sulfide ores
Inventor: GEISLER ROBERT A
IPC: C22B19/00
Filed: 2009-08-19
Abstract: Calcium (Ca), manganese (Mn) and magnesium (Mg) carbonate plus lead (Pb) and zinc (Zn) sulphide minerals e.g. in a sandstone host are selectively in situ leached with selected acid e.g. acetic acid to extract Ca, Mn, and Mg. Ferric salts are then employed to extract Pb and Zn. An inter relationship has been identified between pressure, temperature, target depth and leachate concentration such that carbonate leaching is performed in a manner to prevent carbon dioxide gas (CO2) discharge thereby plugging host rock permeability avenues to preclude further leaching. This requires controlling the rate of acetic acid leaching to be in step with availability of solution to dissolve the resulting discharged CO2. Sulphide leaching is subsequently conducted on the carbonate-depleted host. The two resulting leachates are chemically treated to selectively recover extracted minerals as value added industrially ready products. The method is particularly advantageous in preparing the high purity manganese products necessary for lithium ion batteries because it prevents occurrence of very fine metallic particles in the products that happens during conventional mining (such particles preclude battery operation).
