Patent CA-2594935-A1 (CA)
Inventor: SEHGAL ARUN
IPC: G01R11/00
Filed: 2007-07-26
Abstract: A solution for providing various types of encoder-receiver-transmitter (ERT) devices for use in corresponding types of automatic meter reading (AMR) systems that receive standard consumption messages (SCMs) from ERT devices. According to one aspect, the solution includes maintaining a set of records that associate each issued serial number with a corresponding configured ERT type. A new first ERT device of a first type is configured with a serial number in accordance with the set of records. The first ERT  device may have a common serial number with another ERT device of a different type; but the first ERT device may not have a common serial number with any other ERT  device of the first type.

Abstract: Compartmentalized chips of at least two chemically similar crystallizable thermoplastic polymers each having a different intrinsic viscosity placed in separate zones are disclosed. These compartmentalized chips exhibit thermal characteristics that are different from the traditional technique of homogeneously combining the two materials into the chip. These compartmentalized chips in their amorphous, crystalline and solid phase polymerized forms exhibit a longer crystallization half time than the homogeneous mixture, thus permitting faster injection cycle times when compared to an equivalent homogenous mixture.

Abstract: The invention comprises methods for the photolithographic patterning of features in a photo-curable polymer composition coated onto a plastic substrate. In one embodiment of this invention, the plastic substrate is coated with a reflective film such as a metallic barrier. In another embodiment, the plastic substrate is coated or co-extruded with a polymer barrier layer containing an additive that absorbs the photo-curing radiation.  In yet another embodiment the plastic substrate contains an intrinsic additive that absorbs the photo-curing radiation. Combinations of these embodiments are also within the scope of this invention. The methods of the present invention may be advantageously applied to the fabrication of optical waveguides comprising a photo-curable polymer supported on a plastic substrate, but are applicable to the fabrication of any device or object comprising a photo-curable polymer supported on a plastic substrate.

Title: Multi-stage vector quantization apparatus and method for speech encoding
Inventor: MORII TOSHIYUKI
IPC: G10L19/12
Filed: 1998-10-22
Abstract: A CELP speech coder/decoder capable of accepting a quantization algorithm in a quantizing section using a multi-stage predictive vector quantization method. The vector quantization of a target is carried out in the multistage predictive vector quantization. The target is obtained and is further vector-quantized. A vector of a first target vector is predicted by a predicting section. The searching section carries out the decoding of the vector using decoded vectors from vector codebooks based on the codes for codevector A and codevector B. The amplitude is obtained from the amplifer storing section and past-decoded vectors stored in the state storing section. The apparatus and method reduce the coded distortion. The apparatus may be employed in speech coding and/or decoding for music, images, or in cellular phones.

Abstract: An apparatus for determining the density of insulation in a cavity of a structure includes a sensor that is held in a substantially fixed position relative to the insulation for sensing the force of the insulation against the sensor. The force is used to determine the density of the insulation, which, in turn, is used to determine the thermal resistance or R-value of the insulation. The apparatus may include a fixture for supporting the sensor and holding the sensor in the substantially fixed position. A method for determining the density of loose-fill, blown-in-place insulation comprises the step of providing a structure with a cavity having a known depth. The cavity is filled with insulation. A sensor is held in a substantially fixed position relative to the insulation to measure force exerted on the sensor by the insulation. The measured force is used to determine the density of the insulation. The thermal resistance of the insulation is determined from the known cavity depth and insulation density.

Inventor: TAKEUCHI TOSHI
IPC: C07K16/00
Filed: 2006-04-26
Abstract: A method for generating human IgG1 antibodies with enhanced Fc effector function is disclosed. In practicing the method, an IgG1 Fc look-through mutagenesis (LTM) coding library directed at four receptor-contact regions of the Fc CH2 portion of in human IgG1 Fc is expressed in a system in which the mutated Fc fragments are displayed on the surfaces of the expression cells.  The fragments are then screened for altered binding affinity to a selected Fc receptor or other Fc-binding protein. The selected mutations may be used, in turn, to guide the selection of multiple substitutions in the construction of a walk-through mutation (WTM) library, for generating additional Fc fragment mutations with desired binding properties. The antibodies so produced have a variety of therapeutic and diagnostic applications.

Title: Brake flush accelerator
Inventor: PETTY JON A
IPC: G05G1/48
Filed: 2006-11-15
Abstract: A Brake Flush Accelerator (BFA) selectively depresses a brake pedal while the master cylinder reservoir is under pressure from a brake flush machine, forcing fluid through the system at a very rapid rate. The BFA also provides a thorough flush as internal hydraulic pressure from the master cylinder can be used to exert force to remove contaminates from the brake system. The BFA  exposes the low/no pressure area of the master cylinder to fluid flow from the pressurized master cylinder. When the brake pedal is depressed, a port in the master cylinder is opened which exposes the low/no pressure area of the master cylinder to fluid flow from the pressurized master cylinder reservoir. The BFA  receives its pneumatic power from an air compressor or is easily adapted to a car tire. The BFA can be powered directly from the brake flush machine or attached to a vehicle's battery.

Abstract: A spectrophotometer has a first photodetector (24) and a second photodetector (25) which is displaced spatially from the first photodetector in the direction of increasing wavelength in the spectrum. At any given time the second photodetector receives light at a wavelength which is substantially greater than that being received simultaneously by the first photodetector at that time. The first photodetector has a first range of wavelengths over which it is operable and a first upper operating limit, and the second photodetector has a second range of wavelengths over which it is operable and a second upper operating limit, the second range overlapping the first range and the second upper operating limit being greater than the first upper operating limit. Thus the range of operation is extended, and data in two different ranges is processed simultaneously. The spectrophotometer comprises a housing (1) containing a light source (11), a monochromator (15, 16, 18) and the photodetectors, there being a fibre optic connected to a probe (2) for transmitting light from the light source to a sample to be analysed and receiving light from the sample. Optical components are mounted to a chassis (26) of the housing rigidly, the chassis being connected to the housing by shock absorbing mounts (28, 29). The light source is mounted to the housing by means of an adjuster (24) providing for adjustment laterally with respect to the optical axis of the light source.
