A wireless gateway is provided that connects mobile and remote assets or employees to business enterprise users through multiple wireless networks and the Internet by using web served applications. The central core of the gateway is a location aware business component that sends and receives location based information to and from remote and mobile assets and applies business logic to the location data to enhance and automate business applications run by the enterprise user. This functionality considerably exceeds that of a traditional wireless gateway, which simply manages messages passed through multiple wireless networks but does nothing with the content of the messages. The business logic component provides a common interface and protocol for handling location information and allows applications that follow the protocol to interface with the gateway to take advantage of location information by using location data to trigger events or to tag events, messages, or other data.

This invention relates to a method and device for separating charged particles according to their diffusivities in a separation medium by means of a spatially and temporally varying electric potential. The method is particularly suited to sizing and separating DNA fragments, to generating DNA fragment length polymorphism patterns, and to sequencing DNA through the separation of DNA sequencing reaction products. The method takes advantage of the transport of charged particles subject to an electric potential that is cycled between an off-state (in which the potential is flat) and one or more on-states, in which the potential is preferably spatially periodic with a plurality of eccentrically shaped stationary potential wells. The potential wells are at constant spatial positions in the on-state. Differences in liquid-phase diffusivities lead to charged particle separation. A preferred embodiment of the device is microfabricated. A separation medium fills physically defined separation lanes in the device. Electrodes deposited substantially transverse to the lanes create the required electric potentials. Advantageously, injection ports allow sample loading, and special gating electrodes focus the sample prior to separation. The effects of thermal gradients are minimized by placing the device in contact with a thermal control module, preferably a plurality of Peltier-effect heat transfer devices. The small size of a microfabricated device permits rapid separation in a plurality of separation lanes.

The current landscape for preparative chromatographic RNA purification uses reversed phase HPLC, but this technique presents many issues with process scale up and ion exchange for preparative purification has only been used for short RNAs. The invention provides preparative purification of RNA (e.g., mRNA) using ion (e.g., anion) exchange chromatography that allows for separation of longer RNAs up to 10,000 nucleotides in length via a scalable method. This method avoids problems with current techniques by using low pressure chromatography that is agreeable with existing equipment in cGMP commercial facilities, that uses aqueous-bases solutions as the mobile phase (rather than flammable of greater than 10 mg RNA/mL resin (e.g., using larger pore sorbents, >500 Angstroms, that display greater mRNA binding capacities), and that yields desired RNA salt forms for downstream formulation with no additional manipulation necessary (unlike ion pair reverse phase techniques).

An approach for stabilizing the interactions between a plasma and the generator powering the plasma is provided. Reactive elements disposed between the power generator and plasma operate to modify the apparent impedance characteristics of the plasma such that the trajectory of the plasma load impedance as a function of power is substantially aligned locally with the contours of constant power output in impedance space. In this way, instabilities in the generator and plasma system are avoided because reinforcement or amplification of fluctuations in plasma impedance due to interactions between the generator and the plasma are reduced or eliminated. The reactive elements may be variable in order to align plasma trajectories and generator power contours under a range of process conditions.
