Abstract: A microbial detection apparatus is provided. The apparatus includes a parabolic reflector. A light source is configured to direct a beam of light toward the focal point of the parabolic reflector. A fluid flow tube passes through the focal point of the parabolic reflector, such that the light beam path and the flow tube intersect at the focal point of the parabola. The fluid flow tube is configured to contain a flow of fluid. A first detector is included for detecting fluorescence light emitted from microbes within the fluid passing through the flow tube. A second detector is included for detecting Mie scattered light from particles within the fluid passing through the flow tube.

Abstract: The present invention includes a method to update a first key maintained at one or more client devices and automatically updates a second key maintained at one or more wireless network access points to match the first key to allow the client devices to access the wireless network.

Abstract: Picture frames and display devices that use a layer of a dichroic optical material placed between two transparent substrates to control an optical transmission at different locations across the layer by applying control voltages at the different locations to display digital images.

Abstract: A signalling switch for use in information protocol telephony is provided, which can initiate, sustain, and terminate a plurality of discrete voice and data calls simultaneously. A plurality of cards are mounted on a computer bus, where the first card is a single board computer whose function is to act as the operations and maintenance control card for the switch. A non-system card functions as a message transport controller card; and there is at least one further non-system card which functions as a master application controller card. Local bus communication among the non-system cards is provided by a local bus found on the message transport controller card. Telephone routing information protocol software is resident in the switch, and the switch communicates externally via Ethernet interfaces.

Abstract: A system and method for timely maintaining or establishing an R-P connection after a mobile station (MS) roams from the control of an old base station controller (BSC) to that of a new BSC is provided. The process may be initiated during a registration process of the MS, during an origination process, or during a termination process. A Mobile Service Center (MSC), Visitor's Location Register (VLR), or the MS may be used to store the packet data call status information including point to point protocol (PPP) session status information and configuration information about an old BSC including its related cells and PDSNs. In some cases, this information may also be transferred to the new BSC through a BSC to BSC connection.

Abstract: Disclosed is an apparatus and method whereby a direct base station to base station communication link is used to bypass message transmissions to an MSC in establishing a soft handoff. By using a standardized protocol for both traffic and signaling messages flowing directly from base station to base station, communications with foreign manufacturers base station equipment may be readily accomplished.
