Patent CA-2251629-A1 (CA)
Inventor: WATTS RICHARD P
IPC: G01N35/10
Filed: 1997-04-28
Abstract: A nephelometer and nephelometer/turbidimeter combination of the type useful in automated chemical analyzers is provided. The combination includes a laser for generating a polarized laser beam having an S-wave component and a P-wave component. The beam is split by a beam splitter specially constructed so that a known proportion of one of the two polarized portions of the beam is directed to a reaction container. In the reaction container, a first polarized component of the laser beam is used in a nephelometric chemical analysis. The remainder of the laser beam passes through the beam splitter to a laser control light detector. Before the remainder of the laser beam reaches the laser control light detector, however, the polarized component which is not used in nephelometric chemical analysis is filtered out. The laser control detector uses the non-filtered portion of the laser beam to control the output of the laser. The combination also includes an LED which emits a beam of light at a longer wavelength than that of the laser. Such beam of light is projected through the reaction container to a turbidimeter light detector. A second beam splitter is provided between the reaction container and the turbidimeter light detector to deflect the residual portion of the laser beam away from the laser. This prevents the residual portion of the laser beam from being reflected back into the reaction container.

Patent CA-2256763-A1 (CA)
Inventor: NORSTROEM HANS ERIK
IPC: H01L23/64
Filed: 1997-05-30
Abstract: The quality factor (Q-value) of spiral inductors or coils (305) in IC-circuits is improved by partially removing the semiconducting substrate (301) under the inductor (305) by etching trenches (303), which are refilled with an isolating material. Hence, the losses caused by the substrate (301) are reduced and the quality factor is increased accordingly. The parasitic capacitance to the substrate (301) is also reduced, increasing the resonance frequency of the inductor (305) and extending the useful frequency range of operation of the inductor. Furthermore, by utilizing the uppermost metals of a multi-layer metal structure in the circuit, additional reduction of losses and parasitic capacitance are also achieved. The use of trenches (303) under metal patterns for loss and capacitance reduction is not limited to spiral inductor layouts, and can be used for any metal line, bond pad, etc.

Title: Method and system for allocating costs in a distributed computing network
Inventor: RODEN BARBARA J
IPC: H04L29/06
Filed: 1997-07-11
Abstract: A method and system for providing an end-user with Internet access and allocating a cost associated with that access among the end-user and Internet sites (18) accessed by the end-user. A supervisory program module (58), such as a "JAVA" applet, resides on an originating station (24), such as a personal computer, operated by the end-user. The supervisory program module (58) may be activated by transmitting the supervisory program module to the originating station (24) from an Internet point of presence (22) operated by a local access provider. Alternatively, a trigger may be transmitted from the point of presence (22) to the originating station (24) to activate a supervisory program module (58) already residing on the originating station (24). The supervisory program module (58) monitors the duration of connections with specific Internet sites, and transmits messages to the point of presence (22) indicating the duration of these connections. The local access provider uses the information received in these messages to allocate a cost associated with the access, such as the cost associated with using a telephone network (30), among the end-user and Internet sites accessed by the end-user. Unique keys and time stamps are used as security measures. Unique keys are random identification numbers or codes generated by the point of presence (22). Time stamps are clock readings generated by the originating station, the point of presence, or other network components, are used as security measures.

The drum is rotatable about its longitudinal axis which is inclined downwards the horizontal plane. The drum has a feeding means (9) arranged at the intake end of the drum and adapted to feed material, in the form of suitable fractions of stone material and/or used asphalt, to the drum; feeding means (15, 17) for supplying a binder; a discharge means (13) arranged at the discharge end of the drum and adapted to discharge prepared asphalt paving material from the drum; a drive means (19) for rotating the drum; a burner (11) arranged at the intake end; and a plurality of carrying means (33) arranged in the drum. The carrying means which extend from the intake end of the drum to the discharge end thereof, receive the material from the feeding means and convey it through the drum. Each carrying means comprises a wall portion (35) which is connected to the wall (41) of the drum and which extends inwards from the wall of the drum, and a groove-shaped portion (37) which is connected to the wall portion and which is terminated with a longitudinal free edge (55), which is arranged at a distance from the wall and in front of the wall portion seen in the direction of rotation of the drum. The carrying means are so designed and mutually arranged that the material in a carrying means (57) during one revolution falls over the edge, is caught by the anteriorly situated carrying means (59), seen in the direction of rotation, and is returned to the carrying means which the material initially left via the drum wall portion (61) of the two neighbouring means.

Abstract: A communication system (10) has multiple satellites (20) communicating with ground stations (30) and with base stations (40). The satellites (20) are in non-geosynchronous orbit around the earth (52). A first ground station (30) transmits a data packet to a satellite (20). The data packet includes a sector number which represents an area on the earth (52) where the destination ground station (31) is located. The satellite (20) transmits the data packet to another satellite (20) if the satellite (20) is not serving an area identified by the sector number. This step is repeated until the data packet reaches a most likely satellite (20) that is most likely to be serving the area identified by the sector number. The most likely satellite (20) transmits the data packet to the destination ground station (31) if it is still serving the area identified by the sector number.
