Title: System and method for reading a magnetic tape
Inventor: BORDYNUIK JOHN WILLIAM
IPC: G11B5/627
Filed: 2011-11-08
Abstract: A system for reading a magnetic tape is provided. The system comprises a magnetoresistive head, a tape controller, an analog-to-digital converter and a processing unit. The tape transport controller controls a movement of a magnetic tape with respect to the magnetoresistive head. The analog-to-digital converter generates a signal upon receiving an analog signal read by the magnetoresistive head on the magnetic tape. The processing unit identifies a magnetic flux transition in the signal to detect a bit from the signal from the signal based on the identified magnetic flux transition. Identification of the magnetic flux transition in the signal includes analyzing voltage wave forms of the signal. A method and a computer readable storage medium for reading a magnetic tape are also disclosed.

Title: Identifying matching canonical documents in response to a visual query
Inventor: PETROU DAVID
IPC: G06V30/262
Filed: 2011-12-01
Abstract: A server system receives a visual query from a client system. The visual query is an image containing text such as a picture of a document. At the receiving server or another server, optical character recognition (OCR) is performed on the visual query to produce text recognition data representing textual characters. Each character in a contiguous region of the visual query is individually scored according to its quality. The quality score of a respective character is influenced by the quality scores of neighboring or nearby characters. Using the scores, one or more high quality strings of characters are identified. Each high quality string has a plurality of high quality characters. A canonical source document matching the visual query that contains the one or more high quality textual strings is identified and retrieved. Then at least a portion of the canonical document is sent to the client system.
Patent CA-2820159-A1 (CA)
Inventor: WOODS TIMOTHY JOHN
IPC: F16H33/00
Filed: 2013-07-04
Abstract: This apparatus provides perpetual motion in virtually any medium without the need of fuel, or expensive parts. Two rings-one 'Earth ring' within, and one 'sun ring' without-surround a set of engaging inter-wheels. The rings may be comprised of chain, in which case the inter-wheels are sprockets; or may be geared, in which case the inter-wheels are spur gears.  Where a hubbed earth wheel is used instead of an earth ring, that wheel is fixed to the support frame via an earth shaft. Also, at least one of the inter-wheels is fixed to a support frame via its/their respective shaft/s. (In which case ancillary support wheels must be used to keep the rings aligned.) At least one further inter-wheel, called a moon wheel, is connected from its shaft to the center earth shaft via direct connect arms, or to star shafts via an 'arms and cradles' linkage system. The moon shaft/s also carry/ies very large 'orbiter' wheels that have orbiter walls fixed to their perimeters and are facing toward the middle and each other. A pair of comet wheels is fixed, one wheel at each end, to a comet shaft. The comet shaft is most distal from the center shaft, and from the moon shaft, such that the comet wheels it carries are touching the most distant reach of the inner comet walls. The comet shaft is connected directly to the fixed center shaft via 'center legs'; or is linked to two fixed star shafts via a 'star legs and cradle' system. When the legs of the comet shaft are forced one way or the other, the comet wheels press against the orbiter walls and cause it to rotate, always at a constant distance from the center of the machine; and the other moon wheels must follow. The fixed-place star wheels serve as immediate feedback regulators, owing to the presence of the earth and sun rings, thereby keeping the moon elements in place. Power may be drawn from either/any of the fixed-place star shafts through means of sprocket chain, belting, etc. as the resulting drag on the system is constant on both the earth and sun rings. Where there is a direct linkage from moon shaft and comet shaft to the center shaft a configuration is called TYPE I. Where the moon shaft and comet shaft are connected to fixed star shafts via arms/legs and cradles, such configurations are classed TYPE II. A  third type, TYPE III, occurs where a hybrid motor is formed using direct arms and linked legs, or direct legs and linked arms. The use of the Type II design allows there to be a void within the machine, owing to the presence of suspension arms on each side of the motor, to swing "cradles"  carrying moon shafts and comet shafts according to the direction of exerted force. This walk-through, or 'woom' feature may be useful within a vehicle's fuselage, hull or shell. The cycling continues 'perpetually', until force is removed from the comet leg levers.

Title: Mobile postural screening method and system
Inventor: FERRANTELLI JOSEPH R
IPC: A61B5/103
Filed: 2011-12-23
Abstract: A mobile, hand-held communication device with a display screen and a camera is programmed to perform a postural screening method. An image of a patient is acquired on the display screen having an array of pixels. A pixel to distance ratio of the displayed image is determined. A postural displacement of the patient in the displayed image is calculated using the determined ratio. A gyroscope, accelerometer and/or a level of the device is used to level the camera before capturing the image with the camera. Reference lines are overlaid on the display screen and the image to enable alignment of the image. A reference line on the display screen is used for normalizing a known distance in the aligned image to a reference distance of a known number of pixels on the screen for determining the ratio.

IPC: E21B43/08
Filed: 2014-06-03
Abstract: Cylindrical screens and screen assemblies for use with perforated base pipe or casing for sand control in wellbores have generally longitudinally extending slots punched in the screen. The outer surface of the screen material is deformed below the inner surface causing apertures to form along the longitudinal edges of the slot. The slots are generally longitudinally aligned with the longitudinal axis of the cylindrical screens whether butt-welded or spiral-rolled and welded by determining the angle at which the slots need to be punched to result in such alignment. End caps which connect between the screen and the casing extend over the ends of the cylindrical screen and are welded thereto to minimize sand entry. At least one of the end caps may include an expansion joint to permit relative expansion and contraction between the screen and the casing particularly when used in thermal recovery operations.
