    摘要: A technique for delivering communications services to a large number of users employing relatively inexpensive, widely available handsets. More particularly, the technique utilizes a network apparatus that supports individual access to a community of users and supports access to a wireless communications system (e.g., any well-known Code Division Multiple Access (CDMA) wireless network). That is, the communications hub functions similar to a communications switch with a number users employing inexpensive handsets (e.g., well-known 900 MHz cordless telephones) on one side and the functionality of a mobile terminal, and CDMA interconnection, on the other side. Therefore, the users (i.e., subscribers) employ relatively inexpensive, widely available handsets, in conjunction with the network apparatus, to access a wireless communications network and the associated communications services offered from the wireless service provider.

    摘要: A biological/chemical detector is disclosed that is capable of manipulating liquids, such as reagent droplets, without relying on microchannels. In a first embodiment, fluid flow is passed through the detector, thus causing particles wholly or partially containing an illustrative chemical compound or biological species to be collected on the tips of nanostructures in the detector. A droplet of liquid is moved across the tips of the nanostructures, thus absorbing the particles into the liquid. The droplet is caused to penetrate the nanostructures in a desired location, thus causing the chemical compound or biological species in said liquid droplet to come into contact with, for example, a reagent. In another embodiment, a fluid flow is passed through the nanostructured surfaces of the detector such that the chemical compound and/or biological species are deposited between the nanoposts of a desired pixel. A droplet of liquid is moved across the surface to that desired pixel and is caused to penetrate the nanostructures of the pixel, thus contacting a reagent.
