Patent CA-2427889-A1 (CA)
Inventor: VOON GERARD G V
IPC: F03G7/10
Filed: 2003-04-22
Abstract: A new technology for energy (power, electricity) generation.      This design uses gravity, leverage, shifting water (or other ) weights inside stacks of specially shaped tanks. All the tanks will be secured probably by rails (clamps) to a rotating chain(s) that spins turbines that use magnets to generate power. The shape of the chains will have a height that is higher than its width. The height will depend on the appropriate scale.      The scale will depend on kilo watt hours of electricity needed.      Since the design is thin and tall, it can be placed side by side to yield multiple energy generations units in a set.      Additionally, this technology can be used and easily installed on any planet from Earth, Mars to Jupiter.

Title: Bit rate reduction in audio encoders by exploiting inharmonicity effectsand auditory temporal masking
Inventor: LAHDILI HASSAN
IPC: G10L25/90
Filed: 2003-08-27
Abstract: The present invention relates to a method for encoding an audio signal. In a first embodiment a model relating to temporal masking of sound provided to a human ear is provided. A temporal masking index is determined in dependence upon a received audio signal and the model using a forward and a backward masking function. Using a psychoacoustic model a masking threshold is determined in dependence upon the temporal masking index. Finally, the audio signal is encoded in dependence upon the masking threshold. The method has been implemented using the MPEG- 1 psychoacoustic model 2. Semiformal listening test showed that using the method for encoding an audio signal according to the present invention the subjective high quality of the decoded compressed sounds has been maintained while the bit rate was reduced by approximately 10%. In a second embodiment, the inharmonic structure of audio signals is modeled and incorporated into the MPEG-1 psychoacoustic model 2. In the model, the relationship between the spectral components of the input audio signal is considered and an inharmonicity index is defined and incorporated into the MPEG-1 psychoacoustic model 2. Informal listening tests have shown that the bit rate required for transparent coding of inharmonic (multi-tonal) audio material can be reduced by 10% if the modified psychoacoustic model 2 is used in the MPEG 1 Layer II encoder.

Title: Method of analyzing and controlling the uniformity of tires
Inventor: CHANG LOH-YI
IPC: G01M17/02
Filed: 2001-06-01
Abstract: A method of controlling uniformity during tire manufacture includes the steps of selecting a target attribute and assigning a target value thereto, measuring the target attribute in a subject tire at a first rotational speed approximating highway speed and measuring in the subject tire indicator attributes a second rotational speed lower than the first rotational speed.  The indicator attributes are condensed via a multivariate process to determine which attributes are the most strongly related to the target attribute. Next a plurality of predictors for the target attribute is determined, each predictor having components including at least one indicator attribute. From the plurality of predictors, at least one best predictor is selected. The measurements for the indicator attributes making up the selected predictor are compared to limit values for the indicator attributes, and, responsive to the comparison, the tire manufacturing process may be controlled to correct any deviation between the measured attribute and the limit value for at least an additional subject tire. Production tires are measured for the components of the selected predictor at the second rotational speed, and a value for the target uniformity attribute is predicted based on the selected predictor for the additional subject tire. The predicted value is compared to the target value to allow for sorting or grading the tires.

Title: Method and integrated circuit for tuning an lc resonator and electrical apparatus comprising an lc resonator
Inventor: PLATZ RAINER
IPC: H01Q/
Filed: 2003-11-05
Abstract: For tuning an LC resonator (2) which particularly comprises a miniaturised antenna coil (L A), a variable capacitance (C T) is connected in parallel to the LC resonator (2). At manufacturing time, a maximum resonance frequency of the LC resonator (2) is measured when the variable capacitance (C T) is set to its minimum value, a minimum resonance frequency of the LC resonator (2) is measured when the variable capacitance (C T) is set to its maximum value, and coded values of the measured maximum and minimum resonance frequencies are stored in non-volatile memories (F min, F max). At operations time, a binary tuning code (B) is computed as a linear interpolation between the stored values of the minimum and maximum resonance frequencies for a target resonance frequency (f t). The LC resonator (2) is tuned to the target resonance frequency (f t) by selectively connecting separate binary weighted capacitors (C n-1, ..., C2, C1, C0) of the variable capacitance(C  T)in parallel to the LC resonator (2) in accordance with the value of the computed binary tuning code (B).

Title: Infusion device and driving mechanism for same
Inventor: GRAY JOHN F
IPC: A61M5/142
Filed: 2002-09-04
Abstract: A drive mechanism for delivery of infusion medium a coil capable of being electrically activated to provide an electromagnetic field. The coil surrounds a piston channel extending in an axial direction. The piston channel provides a passage for communication of infusion medium to an outlet chamber located at one end of the piston channel. An armature is located adjacent the coil, on one side of the axial channel. The armature is moveable toward a forward position, in response to the electromagnetic field produced by activation of the coil. A piston is located within the piston channel and is moveable axially within the channel to a forward position, in response to movement of the armature to its forward position. The armature and piston are moved toward a retracted position, when the coil is not energized. In the retracted position of the piston, a piston chamber is formed between the piston and a valve member and is filled with infusion medium. As the piston is moved to its forward position, the piston chamber volume is reduced and pressure within the piston chamber increases to a point where the pressure moves the valve member into an open position. When the valve member is in the open position, medium from the piston chamber is discharged into an outlet chamber located on the opposite side of the coil relative to the armature. An outlet is provided in flow communication with the outlet chamber, for discharging infusion medium from the outlet chamber.

Title: Substrate with membrane seam plates fixed thereon for precise placement of seam plates on roof decking assemblies
Inventor: SCHMIDT DANIEL T
IPC: E04D3/36
Filed: 2004-03-22
Abstract: A seam plate implement assembly comprises a substrate having a longitudinal extent and upon which a plurality of seam plates are fixedly disposed at predetermined uniformly spaced longitudinal positions which correspond to the transverse spacing defined between the crest portions of an underlying corrugated roof decking substructure. In this manner, when a particular one of the membrane plates is fixedly secured to one of the crest portions of the underlying corrugated roof decking substructure by suitable threaded fasteners, the remaining membrane plates will be automatically properly aligned with the other crest portions of the underlying corrugated roof decking substructure so as to automatically ensure proper and secure fixation of the seam plates upon the roof decking assembly. When the seam plate or membrane plate implement assembly is used with a non-corrugated roof decking substructure, the seam plates are disposed at predeterminedly spaced locations upon the substrate so as to provide the environmental membranes with sufficient uplifting force resistance. The substrate may have a C-shaped or V-shaped cross-sectional configuration for enveloping each one of the seam plates, or may comprise a mesh member through which prong members of the seam plates are extended and folded so as to secure the seam plates upon the substrate.
