Patent CA-2279750-C (CA)
Inventor: HAMPEL KARL GEORG
IPC: H01Q3/32
Filed: 1999-08-04
Granted: 2002-02-26
Abstract: The invention is a device that provides a phase-tunable antenna feed network that allows beam-steering and beam-width variation with simple actuation, at low cost, and with high rf performance. The device provides a series-feed where signal power splitters and phase-shifters are alternately disposed in series. Each phase-shifter consists of reflection-mode phase-shifter elements that operate in conjunction with an isolation device. This avoids the critical resonance condition between periodically aligned phase-shifters over the entire tuning range, since the isolation devices can easily be matched and/or aligned with non-resonant spacing. The main feed-line interconnections have the same impedance, thereby enabling the utilization of the same phase-shifter design for the entire network. Moreover, a common driving mechanism can be used for the phase-shifters to steer the antenna beam. Splitting the array into two sub-arrays with individual collective driving mechanism further allows beam-width variation by steering the beams of both sub-arrays in opposite directions. The device is further compatible with symmetrical series network designs that have better frequency response. The series feed network preferably uses a phase-shifter for shifting a signal propagating through a transmission line by moving a conductive construct between an active line and a ground plane of the transmission line. The conductive construct capacitively couples with either the active line and/or the ground plane, forming a capacitive shunt that reflects a significant part of the signal. The remaining portion of the signal is reflected at a terminated end of the transmission line, resulting in substantially no signal loss.

Title: A method and an apparatus for plasma treating the surface of substrates
Inventor: KELLER SILVANO
IPC: C23C4/134
Filed: 1999-11-17
Granted: 2006-02-28
Abstract: An apparatus for plasma surface treating of substrates comprises a treatment chamber that can be evacuated as well as two adjoining pre-treatment chambers that can be evacuated as well. Both of the pre-treatment chambers are provided with a plasmatron. While a first substrate is plasma coated in the treatment chamber, a second substrate to be subsequently plasma coated is simultaneously pre-treated in a pretreatment chamber by means of the plasmatron received in that chamber. For this purpose, the second substrate is alternately heated and cleaned, whereby the second substrate, during the cleaning operation, is connected as cathode to create an electric arc between the substrate and the plasmatron. By means of such a method and such an apparatus, the throughput can be substantially increased, while the quality of the coating meets the highest requirements.

Granted: 2005-06-07
Abstract: A receiving device for a mobile station receives signals transmitted from a base station having a time-switched transmission diversity (TSTD) function. In the receiving device, a despreader despreads channel signals which have been transmitted in a TSTD mode of operation. A pilot separator separates a pilot signal from the despread channel signals. A channel estimator generates a channel estimation signal by selecting pilot signals transmitted from a same antenna of a transmitter according to a TSTD pattern of the transmitter. A compensator compensates the channel signals with the channel estimation signal.

Abstract: The invention relates to a router device (200) having a plurality of ingress line interface cards (LICs)(212, 214, 216, 218), a plurality of egress LICs (222, 224, 226, 228)), a backplane (230) and a controller (240). Transmission of signals from the ingress LICs (212, 214, 216, 218) to the controller (240) and likewise the transmission of signals from the controller (240) to each of the ingress LICs (212, 214, 216, 218) and each of the egress LICs (222, 224, 226, 228) takes place across the backplane (230). Each ingress LIC (212, 214, 216, 218) is provided with a dedicated timeslot in which it can send information to the controller (240) via connection (242). Information is sent in a slice within the dedicated timeslot and each egress LIC (222, 224, 226, 228) ignores data sent by a given ingress LIC within the timeslot assigned to said ingress LIC. A similar system is used for transmission of communications from the controller (240) to the LICs. It is thus possible to avoid provision of additional, dedicated communications paths between the LICs (ingress and egress) and the controller (240).
