Title: Method for controlling hydraulic system for construction machine
Inventor: LEE SANG-HEE
IPC: F15B13/043
Filed: 2012-07-16
Abstract: Disclosed is a method for controlling a hydraulic system for minimizing a loss of pressure by expanding the open area of a joining spool if a work device such as a boom or the like operates autonomously. The present invention provides a method for controlling a hydraulic system, comprising: a first step for detecting pilot signals according to the operations of operation levers for first and second working devices by first and second pressure-sensing devices and respectively transmitting the pilot signals to a controller; a second step for determining whether the operation lever for the first working device operates autonomously; a third step for supplying second signal pressure by an electronic proportional valve to a joining spool in order to expand the open area of the joining spool with respect to the same operation pressure of the operation lever for the first working device and discharging the operation oil discharged from a second hydraulic pump, in proportion to the operation amount of the operation lever for the first working device, when the operation lever for the first working device operates more than a set section if the first working device operates alone due to the independent operation of the operation lever for the first working device; and a fourth step for supplying the second signal pressure by the electronic proportional valve to the joining spool so as to be proportional to the operation amount of the operation lever for the first working device and divisionally supplying the working oil discharged from the second hydraulic pump to the first and second working devices, if the first and second working devices operate in combination due to the simultaneous operations of the operation levers for the first and second working devices.

Title: Secure biometric authentication
Inventor: STEINAR PEDERSEN
IPC: G06F21/32
Filed: 2015-10-14
Abstract: Authenticating a user where a fingerprint 4 of the user is scanned at a fingerprint sensor 2 and received at the same time and the same sensor is a user-specific code comprising drawing a pattern of one or more lines by swiping a finger on a portion of the fingerprint sensor. The direction along a longitudinal axis of a users finger when depositing the fingerprint is determined and the direction is used to define the orientation of a first axis of an X-Y conditional coordinate system 5 where direction of the Y-axis of the conditional coordinate system 5 can be established as parallel to the movement of the users finger 9. The line gestures are further guided by a virtual, rectangular frame on the sensor surface where the vertical sides of the frame are aligned with the defined Y-axis and the horizontal sides are aligned with the defined X-axis of the coordinate system. The virtual frame serves as a codification frame for translating drawing patterns into number or letter codes.

Title: Inertial navigation system
Inventor: JOHN KEITH SHEARD
IPC: G05D1/10
Filed: 2015-12-07
Abstract: An inertial measurement system for a spinning projectile comprises a roll gyro oriented parallel to the spin axis of the projectile, the gyro arranged with two other gyros to define a 3-dimensional coordinate system. A controller computes a current projectile attitude comprising roll, pitch and yaw angles from the outputs of the gyros; calculates a roll angle error based on the difference between the computed the expected pitch and yaw angles; provides the roll angle error as an input to a Kalman filter that outputs a roll angle correction and a roll rate scale factor correction; and applies 280 the corrections to the output of the roll gyro. The Kalman filter models roll angle error as a function of roll rate and one or more wind variables. The system provides improved calibration of the roll axis rate gyro scale factor, e.g. in the inertial measurement unit of a rolling projectile. An Euler angle filter estimates the roll angle error without the use of the Kalman filter; this is then provided as an input to the Kalman filter which can then operate in a stable manner. The system can estimate and correct for crosswind effects that would otherwise significantly degrade performance.

Title: Directional drilling system and methods
Inventor: BHARGAV GAJJI
IPC: E21B7/06
Filed: 2013-12-30
Abstract: A directional drilling steering system is configured to direct a tubular sleeve arranged at the bottom of a drill string adjacent the drill bit at a selected tilt angle with respect to the longitudinal axis of the uphole drill string and at a selected azimuth. Tilt angle can be achieved by axial movement of one or more pistons in engagement with the downhole tubular sleeve. Azimuth can be achieved by axial movement of the pistons or by rotation of the drill string. The movement of the downhole sleeve along the deviated path causes movement of the drill bit shaft and the drill bit coupled thereto.
