Patent CA-2210142-C (CA)
Inventor: GRONVALL DANIEL
IPC: A61B5/145
Filed: 1996-11-13
Granted: 2005-11-01
Abstract: A reusable accessory for a sensor (201) (such as a pulse oximeter (200) or a plethysmograph) that allows close conformance between the sensor heads (205, 206) and the patient tissue to be measured. The accessory thus provides both a key advantage of adherent sensors (i.e. close tissue-sensor conformance) and a key advantage of rigid structure sensors (reusability). The accessory provides a structure for mounting the sensor heads (205, 206), whereby the sensor heads (205, 206) can pivot about their respective points of attachment to the mounting structure within first and second voids, respectively, thereby allowing the sensors to closely conform to the patient tissue. In one embodiment, the mounting structure includes a spring (209, 210) containing two coils, and two frames surrounding the voids and connected to the coils, each frame having an end shaped to fit a portion of a sensor head (205, 206) and onto which a sensor head (205, 206) is mounted. Another aspect of the present invention concerns the use of flexible sleeves (204a, 204b) to cover the sensor heads (205, 206) when mounted on a reusable accessory. The sleeves (204a, 204b) can be replaced or cleaned between patient applications, thereby reducing the risk of cross contamination between patients, and reduce the amount of shunted light. Yet another aspect of the present invention involves sensory accessories providing light shields that reduce shunting for non-flat site applications and yet do not interfere with sensor-tissue conformance in flat site applications.

Title: Detection method for the transmitter identification information signal in the null symbol of a dab stream
Inventor: GRASSLE JURGEN
IPC: H04H60/50
Filed: 1998-09-04
Granted: 2008-08-19
Abstract: A DAB stream starts with a so-called null symbol for the receiver synchroniza- tion carrying a transmitter identification information, i.e. TII, signal. Each transmitter in the single frequency network is assigned a main id and a sub id for unique identification. This identification is mapped to a certain pattern with 16/8/4/2 set carrier pairs in the spectrum of the null symbol according to the DAB modes I-IV. Based on mode II which has 384 valid carriers a so called comb block is defined. For modes I and IV this block is repeated 4 and 2 times, respectively. For mode III only a half block is available. This pattern is transmitted every 2nd DAB frame in the null symbol. To detect the set carriers the steps of differential demodulation of TII pairs in-cluded in the spectrum (S1(.omega.)) of every second null symbol of the incoming DAB stream (S1, S2, S3) to respectively obtain a demodulated null symbol, correction of carrier phases of the demodulated null symbol spectrum (S4), de-termination of a threshold. (S7), and decision if a carrier is set or not by com-paring the carrier level to the determined threshold (56) are performed.

Abstract: In the case of a method and of a device for automatically extracting milk, long milk hoses having a large internal diameter are used, which permit an optimum mode of operation in combination with the highest possible flows of milk. In addition, the flow cross-section of the milk discharge sys-tem of the milking unit is controlled during the relief cy-cle at a predetermined point in dependence upon the pressure prevailing below the teat or in dependence upon the milk to be discharged. In this way, cows having different flows of milk can be milked in the best possible manner with the aid of only one kind of long milk hose.

Title: Apparatus and method for three-dimensional contouring
Inventor: HALLSTROM CHARLES A
IPC: E01C19/00
Filed: 1998-10-30
Granted: 2009-07-14
Abstract: A contouring device and method for contouring three-dimensionally curved surfaces includes an elongated contouring assembly that is supported at opposite ends by a pair of fluid cylinders. The fluid cylinders are controlled to raise and lower the ends of the contouring assembly independently of each other, thereby allowing the contouring assembly to create a three-dimensionally curved surface as it passes over an area to be contoured. The control of one of the fluid cylinders is based on a comparison of the measured position of a first end of the contouring assembly with a profile of the surface to be leveled that is stored in a computer memory. The measurement of the position of the first end of the contouring assembly is achieved by a tracking device which tracks the position of a target positioned on the first end of the contouring assembly and which determines the three dimensional position of the target. A proximity sensor measures the position of the second end of the contouring assembly from a surface and outputs a control signal that adjusts the height of the second end of the contouring assembly to follow the surface. Alternatively, a second target positioned on the second contouring assembly end is tracked by a second tracking device to determine the three--dimensional position of the second end. The contouring assembly preferably has a plow, rotating auger, and a vibratory screed positioned adjacent and parallel to one another in an orientation transverse to the direction of motion of the contouring assembly. The plow, rotating auger, and vibratory screed are all pivotable about an axis parallel to their longitudinal direction. A pivot or tilting controller controls the tilting of the plow, rotating auger, and vibratory screed to follow the slope of the profile stored in computer memory.

Abstract: This invention is directed to a multi-layer laminated shingle, wherein each shingle layer comprises granule and bituminous coated web, with the layers laminated together and with the butt zone of the base layer disposed against a bottom surface of the tab zone of the secondary layer and with the tab zone of the base layer disposed against the bottom surface of the butt zone of the secondary layer. The shingle lends itself to having tabs spaced by voids. Because the tabs in the base layer are inverted, the base layer's butt zone is visible through voids in the tabs of the secondary layer.      The method of making the shingle lends itself to complementally cutting out the tabs of two side-by-side shingles from a given line. Enhanced nailing area is provided, and stacking of shingles for packaging is facilitated.
