Patent CA-2286773-C (CA)
Inventor: LUDWIG BARBARA ANN
IPC: D21H27/02
Filed: 1998-04-02
Granted: 2004-07-27
Abstract: A process for high pressure embossing a single ply of paper and the paper produced thereby. The embossing process requires two rolls, a pattern roll (30) and an anvil roll (32). The rolls are loaded together at a pressure of at least 1000 psi at the nip. A single ply of paper is embossed in the nip. The embossments of the paper do not extend outwardly beyond the thickness of the paper to have any out of-plane deformation. The embossments are typically glassined.      The resulting paper has an aesthetically pleasing appearance, without undue loss of tensile strength from the embossing process.

Abstract: A secure internet telecommunications system for transmitting, data has a security module which is positioned between a first computer and a a network. The security module has a cryptographic logic device that encrypts and decrypts data transmitted from the first computer in accordance with known standard encrypting and decrypting protocols. The security module is actuated by the insertion of a cryptographic token bearing a user's cryptographic key information and/or other user information. This token is first enabled to make this information available to the security module. The cryptographic token is preferably a PC card, an IC card or a Smart Card having a contact sensitive graphical user interface. The token captures through the interface a template associated with a user's ideogram signature information and stores this template and other information in memory. The template is then compared with subsequent inputs of this ideogram signature information from the user and verified to enable the cryptographic token to function with the security module. The cryptographic token may have either an independent power source permitting the token to be enabled off line from the security module or alternatively relies on the power supply of the security module. The present invention has advantage in that user information is stored on a token device which must be enabled by a user and temporarily connected with the security module to permit the use of the user information.

Granted: 2005-03-15
Abstract: A method and apparatus are provided for use in a transceiver of a wireless system that enable analog mode operations to be performed using in-phase (I) and quadrature (Q) values. When operating in the analog mode, the apparatus comprises a processor that receives digital I, Q pairs relating to audio or data signals and performs FM  demodulation to generate information content relating to the audio or data signals. When receiving data in the analog mode, the data is in a particular format. In order to decode the data, the processor looks at each bit of the data for five repeats of Radio Link Words (RLWs) and generates and stores a confidence factor associated with each bit. The confidence factor is based on how closely the waveform represents a 1 or a 0 as well as the signal strength. If the waveform has relatively little noise and if the RF signal strength is relatively high, the processor assigns more weight to its determination as to whether the waveform represents a 1 or a 0. Once this process has been performed for each repeat of the current RLW, the processor takes the sum of the confidence factors associated with each bit and compares the sum to a threshold level to determine whether the bit is a 1 or a 0. A  signaling tone detection routine is utilized to distinguish between when data is being received and when signaling tone is being received.

Granted: 2006-03-28
Abstract: A method for manufacturing a drive plate or one-piece torsional vibration damper retainer plate (20) for a torque converter (26) is disclosed. The retainer plate includes an annular periphery (36) curled into a generally C-shaped channel (4b) for retaining at least one spring (56). The method includes the following steps. First, the retainer plate (20) is stamped primarily to form a central plate segment (34), an annular periphery (36), and a hub opening (44). Next, the annular periphery of the retainer plate is pre-curled. The plate is then heat treated to enhanced the physical properties of the retainer plate. The spring is disposed within the pre-curled annular periphery. Finally, the annular periphery of the retainer plate is completely curled into the generally C-shaped channel to substantially surround the spring thereby preventing the spring from being removed from the C-shaped channel of the retainer plate during operation of the retainer plate.

Title: Vortex gas flow interface for electrospray mass spectrometry
Inventor: WELLS GREGORY J
IPC: G01N27/62
Filed: 1999-09-27
Granted: 2004-05-25
Abstract: An apparatus for efficiently removing a carrier liquid from charged liquid drops formed by electrospray ionization prior to introduction of the drops into a mass spectrometer (209). A central capillary tube (210) connects a region of the low pressure vacuum system containing the mass spectrometer (209) with a region at substantially atmospheric pressure, in which ion formation is produced by electrospray ionization. Heated, drying gas flows through a plurality of vortex forming channels (214) symmetrically disposed about the axis of the central capillary tube (210) which provides an entrance to the spectrometer (209). Gas exiting the vortex forming channels (214) enters tangentially to the inside of a vortex drying tube (222) with a small helix angle, causing the gas to swirl around the tube, forming a vortex. The vortex drying gas flows in a direction that is substantially transverse to the axis of the entrance capillary into the mass spectrometer (209). The vortex gas intersects the electrospray, separating undesired large drops from smaller drops by a vortex gas flow which imparts a centrifugal force to the drops. The largest drops are driven to the wall of the drying tube (222) and caused to fragment into smaller drops by evaporation and collision with the wall (222).
