A touch system comprises overlapping coordinate input sub-regions defining a generally contiguous input surface. Each coordinate input sub-region generates pointer coordinate data in response to pointer contacts thereon. When a pointer contact is made on a region of a coordinate input sub-region that overlaps with an adjacent coordinate input sub-region, each overlapping coordinate input sub-region processes acquired images to derive pointer data and triangulates the position of the pointer using the derived pointer data. Thereafter, the triangulated positions generated by the overlapping coordinate input sub-regions are processed in accordance with defined logic thereby to determine the position of the pointer contact relative to the touch surface.

A closed-loop transmitting antenna diversity method, and a base station and mobile station apparatus therefore in a next generation mobile telecommunications system, the closed-loop transmitting antenna diversity method having a plurality of antennas in a mobile telecommunications system, including the steps of (a) measuring the changed amount per unit time of the phase difference between antennas for each of the plurality of antennas which are used in a base station; (b) transmitting the result of measuring as feedback information for adjusting transmitting antenna diversity; (c) receiving and interpreting feedback information in the base station; (d) calculating the weighted value of array antennas for each antenna, using the interpreted feedback information; and (e) multiplying data which is to be transmitted from the base station to a mobile station by the array antenna weighted value, and outputting the result through a corresponding antenna. Here, the changed amount per unit time of the phase difference between antennas is obtained by subtracting the previous phase difference between antennas which the base station knows from the phase difference between antennas which is calculated by a current mobile station.

Devices and methods for registering, dynamically referencing, and navigating an anatomical region of interest of a patient are provided using a tracked Kirschner wire (K-wire), where the K-wire includes a position-indicating element.

A system and method for assessing the severity of medication errors associated with intravenous administration is provided. A harm index database includes harm index values for various parameters of medication administration. A medication administration device may access this database and assess the overall harm index for particular errors in order to provide appropriate alerts based on the severity of the error. Further, assessment of the harm index value may be used retrospectively to provide reports of event logs that include an overall harm index value associated with each alert.

Described herein is a method and system for marker-less three-dimensional modelling, fitting and tracking of a skeletal representation of an object in a three-dimensional point cloud. In particular, it concerns the tracking of a human user skeletal representation with respect to time. The method comprises inputting a three-dimensional point cloud derived from a depth map; predetermining a set of control points representing the skeleton of the user, determining a start-up skeleton pose, obtaining an orthographic representation of the user 3D point cloud projected onto a grid by sampling the 3D point cloud with a predetermined static size, determining a set of curvature centres points approximating central axes of main parts of the user, determining the torso plane, and refining and / or defining the principal direction of the body. The method comprises then the step of performing iterative local and global fittings of the set of control points onto the user 3D point cloud and the associated data such as the curvature centre points, using topological and geometric constraints so that to track skeleton posture along the time. Stabilising the skeleton pose; resolving ambiguities; and providing a suitable output are then the last steps of a preferred embodiment of the invention.

Methods and associated systems are disclosed for POS devices and associated monitoring and diagnostic applications. POS peripherals in a POS device include data memory for storing device configuration and status information. A diagnostic application installed in the POS device monitors and diagnoses the POS device. The diagnostic application monitors the interactions between hardware in the POS device and applications that interface with the hardware. The diagnostic applications analyze these interactions, the configuration and status information and any logs it creates to provide diagnostic information. The POS device also includes several interfaces to access the diagnostic application.

The present invention provides a system and method for enabling prospects to contact sponsoring advertisers on the telephone directly from an Internet-based advertisement with just a single-click and provides the ability to track from which Internet location (URL) these telephone calls are generated, thereby enabling a more convenient and efficient telephone call measured, Internet based pay-for-performance advertising platform.
