Patent CA-2346785-A1 (CA)
Inventor: FURUKAWA HIROSHI
IPC: H04J13/00
Filed: 1999-10-22
Abstract: Degradation of the reception quality and reduction in the number of terminals accommodated are prevented even if signal components are received as an interference at different demodulating timings thereof by distortion of the transmission line. A mobile station receiving method is for a downstream line of a CDMA (Code Division Multiple Access) cellular system in which a base station spreads the spectrum of a transmission signal to be transmitted to mobile stations by means of mutually orthogonal spreading codes, and superposes and transmits the spread-spectrum transmission signals synchronously, and the mobile stations receive the transmitted signals subjected to transmission line distortion as a result that the transmitted signals have passed through radio transmission lines of different delay times.  In the method, the signals transmitted and subjected to the distortion are equalized and demodulated by using a filter having characteristics opposite to those of the radio transmission lines.
Patent CA-2347321-A1 (CA)
Inventor: KEPES GEORGE B
IPC: G02B6/44
Filed: 2001-05-10
Abstract: A high-speed binder application device for wrapping binder material about a bundle of buffer tubes that contain optical fibers includes a pair of opposite facing binder heads mounted on a pair of hollow shafts, each shaft being driven in rotation by a concentric drive. Each binder head includes a light-weight synthetic guide drum that dispenses binder material from a reel and onto the bundle of buffer tubes as it is advanced through the hollow shafts. The lightweight and high strength of the synthetic guide drums allows the drums to be rotated at speeds in excess of 4000 RPM. Each drive is concentrically mounted on its respective shaft which reduces or eliminates the shaft bending loads associated with prior belt-driven binder devices, and thus reduces vibrations at higher rotational speeds.

Title: A polysilicon resistor and a method of producing it
Inventor: SMITH ULF
IPC: H01L21/02
Filed: 1999-11-15
Abstract: A resistor has a resistor body (11) of polycrystalline silicon and electric contact regions (23, 15) arranged on and/or in the resistor body (11), so that a resistor part (13) is formed between the contact regions, which gives the resistor its resistance. The material in the resistor body is doped with for example boron to define its resistance. To give the resistor a good long term stability the resistor part (13) is protected by one or more oxide based blocking layers (28, 31) produced from transition metals. These blocking layers can prevent movable kinds of atoms such as hydrogen from reaching the unsaturated bonds in the polysilicon. Such movable kinds of atoms can for example exist in passivation layers (27) located outermost in an integrated electronic circuit in which the resistor is included. The blocking layers can be produced from layers having 30 % titanium and 70 % tungsten, which are oxidized using hydrogen peroxide.

Abstract: A method and apparatus for reducing the strength of interference (e.g., crosstalk noise and/or echo interference) in multicarrier communications.  Carrier subchannels are selected from a plurality of carriers having a range of frequencies. The carrier subchannels are selected by first selecting a first subset of the plurality of carriers, spanning a frequency range having a highest frequency end and a lowest frequency end. Each subchannel in the subset can carry a signal of at least one bit. At least one of the carrier subchannels of the subset for transmitting one or more bits of the digital signals is allocated at one of the ends of the frequency range. Input digital signals are modulated on to the carrier subchannels, are transmitted and received and are demodulated as output digital signals. Carrier subchannels are used in such a way as to reduce or minimize the magnitude of interference phenomena, including near end crosstalk, far end crosstalk, echo, and noise, when transmitting digital signals.

Title: Local area network for distributing data communication, sensing and control signals
Inventor: BINDER YEHUDA
IPC: H04L12/40
Filed: 2000-07-03
Abstract: A network (60) for carrying out control, sensing and data communications, comprising a plurality of nodes (62, 63, 64, 65, 66). Each node may be connected to a payload (49), which comprises sensors, actuators and DTE's. The network is formed using a plurality of independent communication links (61a, 61b, 61c, 61d), each based on electrically-conducting communication media comprising at least two conductors and interconnecting two nodes, in a point-to-point configuration. During network operation, nodes can be dynamically configured as either data-generating nodes, wherein data is generated and transmitted into the network, or as receiver/repeater/router nodes, wherein received data is repeated from a receiver port to all output ports. During normal network operation, the network shifts from state to state. Each state is characterized by assigning a single node as the data-generating node, and configuring all other nodes in the network as repeaters and receivers. The network can be configured in linear or circular topology, or any mixture of both. The nodes and the payloads can each be powered by local power supply or via the network wiring. In the latter case, dedicated wires can be used, or the same conductors may be employed for both power distribution and communication. Network control can be performed external to the network, or by using the network itself as transport for control messages. Shifting from state to state can be done by selecting sequential nodes to be the data-generating node, or by selecting arbitrary nodes to be the data-generating node.

IPC: B01D35/05
Filed: 2002-04-29
Abstract: A rotating brush, mounted on either the outside or the inside of a rotary intake drum, to brush debris from the surface of the drum. The debris is collected in a holding bin located under the brush. The system uses a collector to remove debris from the holding bin when it is filled. In this way, debris is removed completely from the intake, rather than merely brushing it from the drum into the water flow, where it is immediately sucked onto the drum again. The brush rotates the drum as it turns on the surface. This action flicks the debris from the drum into the holding bin. This action automatically removes debris as the drum is working. Other features of the device include a framework for placing and operating the drum and the collection system.
