Patent CA-2168174-A1 (CA)
Inventor: MOCHIZUKI TAKASHI
IPC: H04N19/423
Filed: 1996-01-26
Abstract: In a Hadamard transform coding/decoding method and apparatus, transform coefficients which are obtained through an Hadamard transform operation in an Hadamard transformer 3 are subjected to a bit extract (delete) operation in a bit delete unit 4 to extract 1 bit from the least significant bits of the transform coefficients, 4 bits from the second least significant bits and 7 bits from the third least significant bits and then the extracted bits are output as supplement information Ysup.      In addition, the transform coefficients whose first, second and third least significant bits are deleted, are output from the bit delete unit 4. A bit restoring unit 7 supplements the first, second and third least significant bits of all the transform coefficients on the basis of the 1-bit information, 4-bit information and 7-bit information per block of the supplement information Ysup, which represent the first, second and third least significant bits of the transform coefficients, thereby restoring the transform coefficients. The restored transform coefficients are output to an Hadamard inverse transformer 8 to obtain an image signal.

Title: Method and apparatus for connecting a node to a wireless network using a standard protocol
Inventor: GLEENSON BRYAN J
IPC: H04L29/08
Filed: 1994-10-04
Abstract: Standard protocols, such as those commonly used on LAN networks, are used to connect nodes (104, 106, 108 and 110) to an enterprise network (102) via a wide area wireless network (100). Within the appropriate protocol stacks, the standard protocols are optimized by filtering some packets, eliminating and reducing the size of data packets. The optimized data packets can be transmitted over the wireless WAN, increasing WAN efficiency. The optimization is accomplished by inserting an additional optimization layer (610) into the stack between the existing layers. The optimization layer accepts the normal protocol signals generated by the surrounding layers and generates outputs which mimic protocol layers which the surrounding layers expect. Consequently, the optimization layer operates transparently with respect to the existing protocol stack layers.

Patent CA-2194810-A1 (CA)
Inventor: RUSH JONATHAN EDWARD
IPC: B24B39/00
Filed: 1997-01-10
Abstract: A  thermoformed  cup  or  plate  rim  burnishing apparatus preferably including a plurality of threaded screws, wherein the threaded screws guide and convey a stack  of  thermoformed  cups  or  plates  through  the thermoformed cup or plate rim burnishing apparatus.  The rim burnishing apparatus also includes a heating device for  applying  heat  to  the  rims  on  the  stacked thermoformed cups  or  plates  passing  through  the  rim burnishing apparatus, wherein the threaded screws retain the rims in close proximity to the heating device.   As the threaded screws rotate, the stack of cups or plates are  also rotated as  the threaded screws  advance  the stack  of  cups  or  plates  through  the  rim burnishing apparatus,  so that the entire diameter of the rims on the cups or plates pass by the heating device.   As the portion of the rim of each cup or plate passes adjacent to the heating device,  the rim is heated to a soft moldable  state.    Thereafter,  the  rotating  threaded screws  burnish  the  now  soft  cup  or  plate  rim  by frictionally  rubbing  against  the  cup  or  plate  rim. Additionally,  a heating device may be employed which could generate enough heat to polish the cup or plate rims as they are transported past the heating device via the threaded screws.

Title: A method and apparatus for dynamically determining an operating state of a motor vehicle
Inventor: ASHRAFI BEHROUZ
IPC: B60G17/0195
Filed: 1997-04-22
Abstract: A system for dynamically determining an operating state of a motor vehicle for input to a controller employed to control dynamics of the motor vehicle includes sensors for measuring predetermined vehicle operating state. The system also includes a device for predicting a value for the predetermined operating state, which can then be used to determine a correction factor for the measured operating state signal. This correction factor is proportional to the erroneous component of the measured vehicle operating state. Together, measured operating state and the correction signal are used to obtain a compensated operating state signal. This is particularly useful for reducing the effects of sensor drift and DC offset.

Title: Vertebral instrumentation rod
Inventor: GAYET LOUIS ETIENNE
IPC: A61B17/70
Filed: 1995-11-28
Abstract: This rod comprises a first cylindrical part, being a lumbosacral part (6), which is rigid in all directions, a second part, being a dorsal part (7), which is rigid in a frontal plane, in order to prevent scoliosis, and flexible in a sagittal plane, and a dorsolumbar transition zone (8) connecting the lumbar and dorsal parts and profiled in a progressive manner so that its thickness in the sagittal plane diminishes progressively and its width in the frontal plane increases progressively: this profile is such that the second moment of area of the transition zone remains substantially constant over its entire length. The profile, thus defined, of the transition zone has the aim of avoiding, to a great extent, the risks of breaking due to the fatigue in this zone, resulting from the various movements of the patient in a chair, in particular the flexion/extension movements in a sagittal plane, promoted by the rectangular profile of the dorsal part of the rod.

Abstract: An attenuator capable of controllably attenuating at least two wavelengths of light is configured to have an optical waveguide section having at least two Bragg gratings disposed therein in series. The Bragg gratings have a sloped reflectivity response within a predetermined wavelength range. The sloped response is a function of refractive index variations within each of the grating elements. By compressing or expanding at least one of the gratings, the periodicity is modified so as to shift its central wavelength within a predetermined wavelength range.
