    摘要: Broadband energy incident on a transducer having partially or fully reflective surfaces separated by a gap which is greater than the coherence length of the broadband energy but smaller than one-half a coherence length of a band of energy within said broadband energy causes a portion of the spectral content of the broadband energy corresponding to a coherence length greater than twice the gap length to exhibit interference effects while the average power of the broadband energy remains unaffected. Splitting energy reflected from the transducer into two beams which are filtered at preferably similar center frequencies but with different pass bands yields beams which are radically different in sensitivity to changes in gap length. Analyzing the beams to derive a ratio of powers (since source intensity and fiber attenuation in a common fiber are thus self-cancelling) allows high accuracy and high resolution absolute measurement of temperature, pressure or strain. Effects of any of these physical parameters which are not of interest in a measurement can be fully compensated or made arbitrarily insignificant in a simple transducer structure of extremely small size. Use of broadband energy permits measurement over greater lengths of optical fiber.

    摘要: A nutrition tracking system comprises a nutrition tracking server, a plurality of weight-based food offering terminals, and one or more nutrition and meal information inquiry terminals. Multiple weight-based food offering terminals may be equipped on a food service cart. Each weight-based food offering terminal may be initialized to offer a type of food. The weight-based food offering terminal automatically measures the weight of food taken by a customer or for a customer, calculates the cost of food, and shows the weight and the cost on the display in real time. When the food is paid, the weight-based food offering terminal automatically reports the vending information to the nutrition tracking server. The nutrition tracking server maintains a database for customer meal information and a database for customer nutrition information. Customers may inquire their meal history and nutrition information using the nutrition and meal information inquiry terminals.

    摘要: An authentication server may be adapted to (a) authenticate an authentication peer seeking to establish communications via a first network access node; (b) retrieve user profile information associated with the authentication peer; and/or (c) send the user profile information to a network gateway node that facilitates communication services for the authentication peer. A PMIP network node may be adapted to (a) provide wireless network connectivity to an authentication peer via a first network access node; (b) provide a PMIP key to both ends of a PMIP tunnel between the first network access node and a PMIP network node used to provide communications to the authentication peer; (c) provide the PMIP key to a first authenticator associated the first network access node; (d) receive a request at the PMIP network node from a requesting entity to reroute communications for the authentication peer; and/or (e) verify whether the requesting entity knows the PMIP key.

    摘要: A method or system for managing demand-based multicast services in a wireless communications system (WCS) capable of both unicast and multicast signaling may include providing content requested by a mobile entity in an area of the WCS via a unicast session, determining that a concurrent demand level for the content exceeds a defined threshold for the area of the WCS, and initiating a multicast session for the content in the area of the WCS, in response to determining the concurrent demand level has exceeded the threshold. The method or system may include more detailed operations or aspects for measuring the concurrent demand level, transitioning signaling between unicast and multicast modes, communicating between network components, or related functions.
