Inventor: CISTERNINO FRANCESCO
IPC: H04L7/00
Filed: 1998-12-15
Granted: 2002-02-12
Abstract: The circuit includes an electro-optical mixer, such as an electro-optical Mach-Zehnder modulator,  with non-linear behaviour.   The modulator receives as  input an optical signal at the frequency to be divided, in addition to  an  electric  signal  at  a  given  frequency,  usually corresponding to the frequency deriving from such division. The  output  optical  signal  from  modulator  exhibits  a modulation spectrum containing the frequency difference between the  frequency to be divided and at  least  one harmonic of the frequency of the above electric signal. After having been converted into an electric signal, the output signal of the mixer is subjected to a filtering action to extract the above frequency difference component. This latter one is then used both as electrical signal for the mixing, and as output signal from the divider.   The preferred application is to OTDM systems,  to extract a synchronism signal at tributary signal frequency.

Title: Separator for fuel cell, fuel cell incorporating the same, and method of production of the same
Inventor: YOSHIMURA JOJI
IPC: H01M8/10
Filed: 1999-05-04
Granted: 2004-08-24
Abstract: An inexpensive and corrosion resistant metal-made gas separator includes a base formed by joining formed stainless steel base sheets face to face. The base carries on each of opposite surfaces thereof a first coating layer formed by plating with tin. The base is also coated with a second coating layer of a thermal expansion graphite. When incorporated into a fuel cell, the separator contacts gas diffusion electrodes that are formed from a carbon material similar to the carbon material of the second coating layer, so that the contact resistance is reduced. The first coating layer is formed after a passive state coating is removed from the stainless steel surface, so that an increase in the internal resistance of the separator caused by the passive state coating is substantially prevented.

Patent CA-2291403-C (CA)

IPC: G09G5/393
Filed: 1999-12-02
Granted: 2006-06-06
Abstract: A module is interposed between a multitasking operating system and the device driver for a graphics adapter including a frame buffer with a linear aperture for continuous, asynchronous data transfers. The interposed module may selectively intercept all graphics device driver function requests or simply pass such requests to the device driver, and provides a mechanism for generating graphics output in the frame buffer without utilizing graphics accelerator hardware on the graphics adapter. The interposed module is aware of the start and stop of asynchronous data transfers to the frame buffer. When asynchronous data transfers are started, the interposed module invokes the graphics adapter device driver to obtain access to the frame buffer linear aperture and sets its own internal state to active. While active, the interposed module intercepts all graphics device driver requests and employs its own mechanism to generate graphics output in the frame buffer responsive to such requests, without utilizing the graphics accelerator hardware. Since the graphics accelerator hardware is not utilized, the frame buffer linear aperture always remains enabled. While inactive, the interposed module simply passes all graphics device driver requests to the device driver. The interposed module is preferably implemented in accordance with the GRADD architecture model, with the mechanism for generating graphics output being provided by the VMAN and SOFTDRAW libraries.

Abstract: A position detector is provided for detecting the relative movement of first and second members which are mounted for relative movement along a measuring path. One of the members comprises a magnetic fie ld generator for generating a magnetic field and the other member comprises first and second conductors which are inductively coupled t o said magnetic field generator. The arrangement of the first and second conductors and the magnetic field generator is such that the outp ut signals are generated in a first and second receive circuits whose position varies with the relative movement between the two members. In addition to carrying information relating to the relative position between the two members, the signals induced in the receive circuit s also comprise information defining the relative orientation of the two movable members, and by suitable processing of the received signa ls the relative orientation of the two members can also be determined. In a preferred form of the invention, the system operates to define the relative position and orientation of the two movable members in first and second directions from which the relative orientation o f the two members in a plane containing the two directions can be determined. The signals induced in the receive circuits can also be processed to give an indication of the gap between the two circuits and to provide an indication of the full relative orientation of the two members.

Granted: 2005-10-18
Abstract: A method of serialization including establishing a parameter along a length of the train between a node on one of the cars and one end of the train. The presence or absence of the parameter at each node is determined and the parameter is removed. The sequence is repeated for each node on the train. Finally, serialization of the cars is determined as a function of the number of either determined presences or absences of the parameter for each node. The parameter can be established by providing at the individual node, one at a time, an electric load across an electric line running through the length of the train and measuring an electrical property, either current or voltage, at each node. The same process is used to determine the orientation of a car. The operability of each node is determined by counting the presence and then the absence of a parameter along the whole train.
