Systems and methods are disclosed for providing community-specific content to customers of a merchant's web site. In one embodiment, customers who are electronically referred to the merchant's web site from an affiliate web site, or from one of a group of related affiliate web sites, are automatically assigned to the same community. For example, all customers who enter the merchant's web site from links on golf-related affiliate web sites may be assigned to the community “golf.” Customers may also join or be assigned to communities using other methods. Purchase histories and/or other activity data of the merchant's customers is analyzed periodically to identify specific products or other items that are currently “popular” within the community (e.g., best selling), based upon predefined criteria. This information is provided to members of the community, and possibly to other customers, on the merchant's web site and/or on the web sites of the corresponding affiliates.

A computing device-controlled system is described for the generation of amplitude-modulated pulse-width modulation (AMPWM) signals for use in treating neurological dysfunction via cranial neurostimulation, where the AMPWM signal is specifically designed to minimize the electrical impedance of the tissues of the head. A low-frequency carrier signal is determined for the AMPWM signal by measuring EEG activity at a reference site or sites, generally corresponding with the location of suspected brain dysfunction. Carrier signal frequency is variably related to critical frequency components of the EEG power spectral density, determined from statistical analysis of amplitudes and variability, and dynamically changed as a function of time to prevent entrainment. The AMPWM signal is presented to a subject via a plurality of neurostimulation delivery modes for therapeutic use.

Presented are methods and apparatus for delivering a surgical instrument to a treatment site within the body of a subject, enabling accurate placement of surgical tools in areas not directly visible to a surgeon during a surgical procedure, while reducing or eliminating need for real-time imaging modalities to guide placement of those surgical tools. A treatment tool is guided to a treatment site by placing a guiding element at a reference site within a body of a subject, the reference site having a known spatial relationship to the treatment site, and utilizing a positioning tool to guide a treatment tool to a locus so positioned with respect to that guiding element that the spatial relationship between that guiding element and that locus is substantially similar to the spatial relationship known to exist between the reference site and the treatment site, thereby positioning the treatment tool substantially at the treatment site. Methods and apparatus for treatment of Benign Prostate Hyperplasia are also presented.
