Abstract: An optical device is described. In one embodiment, the optical device includes first and second concave diffraction gratings, first and second concentrators, first and second sets of fibers, and an array of optical elements. The first concave diffraction grating reflects light from an input beam into multiple light waves of different wavelengths focused at spatially separate locations. The first concentrator has a first set of light guiding channels to transfer the light waves. The first set of fibers is optically coupled to the first set of light guiding channels. The array of optical elements include s optical elements that have at least one input and at least one output. Such inputs of each optical element in the array is coupled to one of the first set of light guiding channels. The second set of fibers is optically coupled to outputs of optical elements in the array. The second concentrator has a second set of light guiding channels.  Each of the second set of light guiding channels is optically coupled to a distinct fiber in the second set of fibers. The second concave diffraction grating reflects light from the second concentrator into a single light beam focused at an output fiber.

Granted: 2010-10-26
Abstract: A method, apparatus and all natural bait for trap fishing of crustaceans in the form of dried bait cakes having ground fish parts and a binder of a high bloom number gelatin blended in hot water, which gelatin acts as a binding agent for a dry bait with a finished hardness for insertion in a trap bait bag. This bait - when fished in crustacean-bearing waters -- results in a naturally eroding bait which provides a slow release of small fish particles for chumming purposes, while larger re-hydrated fish pieces remain contained in the bait bag.

Title: Methods and apparatus for coordinating channel access to shared parallel data channels
Inventor: WHITEHILL ERIC A
IPC: H04L12/407
Filed: 2000-11-03
Granted: 2010-07-27
Abstract: A network of nodes communicates using plural, shared parallel data channels and a separate reservation channel.  Access to the data channels is coordinated among the nodes by communicating message requests and corresponding replies on the reservation channel. In addition to a primary transmitter/receiver (e.g., a modem), each node includes a secondary receiver that permits each node to continuously monitor the reservation channel. When not engaged in a message transfer on one of the data channels, the primary receiver monitors the reservation channel. If the primary becomes engaged in a message transfer, the secondary receiver is activated and monitors the reservation channel. Use of the secondary receiver avoids loss of channel access information resulting from use of a single receiver for both the reservation and data transfer mechanisms. By transmitting requests for channel access on the reservation channel and continuously monitoring the reservation channel, message collisions are dramatically reduced.

Abstract: Provided is an improved pressure-type flow rate control apparatus that can control the flow rate of a fluid with great precision using an empirical formula. The empirical formula can provide values that closely fit with the actual flow rates of a compressible fluid under non-critical conditions. The improved pressure-type flow rate control apparatus can control the flow rate of fluid passing through an orifice 4 to a target flow rate with accuracy and at a high speed. The empirical formula for the compressible fluid under non-critical conditions (sub-sonic) is expressed as Qc = KP2m(P1 - P2)n and the flow rate of fluid passing through orifice 4 is calculated by:      Qc = KP2m(P1 - P2)n (K is a proportional constant; and m and n are constants) so that the flow rate of fluid passing through the orifice 4 can be controlled to the target flow rate with high precision at a high speed. Also provided is an improved pressure-type flow rate control apparatus in which a pressure ratio P2/P1 = r, obtained from an upstream pressure P1 and a downstream pressure P2 is constantly compared with a critical value rc, and under critical conditions (r <= r c), the flow rate is calculated by Qc = KP1. Under non-critical conditions (r > r c), the flow rate is calculated by Qc =  KP2m(P1 - P2)n, so that the flow rate is controlled to the target flow rate with accuracy at a high speed depending upon the conditions of fluid.

Abstract: La présente invention concerne un procédé pour commander une installation d'énergie éolienne et une installation d'énergie éolienne, permettant notamment de mettre en oeuvre ledit procédé. Les installations d'énergie éolienne sont bien connues de tous depuis longtemps et sont, ces derniers temps, de plus en plus utilisées comme système de production d'énergie écologique. Cependant, la nature fait que ces installations sont exposées aux conditions météorologiques et l'humidité est un des principaux problèmes posés pour ces installations d'énergie éolienne. Les installations d'énergie éolienne et leurs systèmes électriques doivent donc être protégés de cette humidité dans une large mesure. L'objectif de la présente invention est de supprimer ce risque induit par l'humidité. A cette fin, le procédé pour commander une installation d'énergie éolienne selon cette invention est caractérisé en ce qu'il consiste à détecter la température de la génératrice et la température de l'air aux alentours de l'installation d'énergie éolienne, à déterminer la différence de température, puis à chauffer la génératrice lorsque sa température est inférieure à la température de l'air ambiant.
