摘要:
A method for enabling a system to enhance the accuracy of a location estimate modifies weights in a weight matrix associated with receiver station measurements in parallel with successive refinements of the location estimate. In a typical location estimation scenario, several receiving stations simultaneously derive measurements of a signal from the emitter. Any one of these measurements is in general some function of the emitter location and the receiving station location. The aggregate of these measurements is often in excess of the minimum number of measurements required to provide an estimate of the emitter location. Where such an excess exists, the method proceeds by modifying the weights associated with the measurements in parallel with successive refinements of the location estimate. The method can be implemented over various cellular protocols with a consistent and significant enhancement in the accuracy of location estimates.
摘要:
A star block copolymer and a thermoplastic elastomer including plurality of the star block copolymers and a method of making both is taught. The star block copolymers of the present invention include a core component having either a styrene oligomer or α-methyl styrene oligomer, wherein arms emanate from the core component and the arms are poly(isobutylene-block-styrene) diblock copolymers.
摘要:
The present invention relates to the production of copolymer networks, or co-networks, and to methods for preparing copolymer or co-networks. Furthermore, the present invention relates to products and/or films made from the copolymer and/or co-networks produced in accordance with the synthesis methods of the present invention. Additionally, the present invention relates to crosslinked copolymer and/or co-networks comprising at least one hydrophilic segment and at least one hydrophobic segment. In one embodiment, the hydrophilic segments include at least one poly(vinyl alcohol) (e.g., a poly(vinyl alcohol) modified with acryl amide groups) and the hydrophobic segments include at least one polysiloxane having at least one terminal —OH group (e.g., polydimethylsiloxane (PDMS)). In another embodiment, the copolymer and/or co-networks of the present invention are optically clear and highly oxophilic.
