Abstract: Activity specifications of a plurality of activities to be monitored are received. Each activity specification of the activity specifications identifies properties of a corresponding activity of the activities to be monitored.

Abstract: Methods for repairing a coated part with holes extending therethrough are disclosed. In one embodiment, a method comprises receiving a part where a coating on a first side of the part at least partially obstructs a first opening of a hole on the first side of the part. Measured hole data indicative of a position of a second opening of the hole on a second side of the part opposite the first side is then acquired. Based on the measured hole data, the first opening of the hole is cleared of the coating by laser drilling via the second opening of the hole.

Abstract: Embodiments of the present invention may include a biometrically-enabled gun. The biometrically-enabled gun may detect a presence of a user. In response to detecting a presence of a user, a processor may be awoken from a power-saving mode. The processor may query for a presence of a finger of a user. A fingerprint image may be captured. A template of the captured fingerprint image may be generated. A correlation between the template and one or more authorized user templates may be determined. In response to the correlation exceeding a threshold, a processor may cause an actuator may unlock the gun. In response to a lapse of user contact with the gun, a processor may cause the actuator to lock the gun.

Abstract: Systems and methods for evaluating the corrosion risk in operations with equipment for the handling an acid gas-containing solutes, e.g., an amine unit for the removal of acid gases such as H2S, CO2, etc., are provided. Input parameter values corresponding to geometrical parameters of at least an equipment (or a portion of an equipment) susceptible to corrosion risk, operating parameters, fluid dynamic properties, and properties of the solute are received by the system. Based on the input values, the systems and methods derive a minimum pressure above which acid gas flashing occurs given the localized pressure drop, causing corrosion in the identified location. In one embodiment, the systems and methods provide an assessment correlating acid gas loadings with the corrosion risk.

Abstract: A data delivery system is disclosed in this specification. The system implements an authentication process that verifies data recipients using anonymised geospatial references. Verifying information for each user is stored in client accounts. A server system uses the information to process data requests and generate verification tags for data deliveries. The verification tags include an irreversible encoding of a delivery reference for receipt of a data delivery. Recipient client systems implement a compatible encoding process to generate a delivery authentication tag. The encoded authentication tags are compared to corresponding verification tags to validate data deliveries based on the location of the client system.

Abstract: The present invention relates to a method and apparatus for authentication using physical location, in an embodiment as a second factor in an authentication process. The method comprises the steps of obtaining verified location data based on an actual physical location of a verifying party. The actual physical location is anonymized by an anonymising process, in order to conceal the actual physical location. This allows use of the location data whilst protecting the privacy of the verifying party.

Abstract: A multi-function device with a positioning function and a real time positioning engine is disclosed. The device contains also a shared processor used by the positioning function and other functions of the device, such as a mobile radio-communication function. The positioning engine performs in real time the most computational intensive calculations of the positioning function, such as downsampling, Doppler mixing and correlation calculations. Since the received signal need not be stored, the memory requirements of the positioning function are significantly reduced if aiding data is available.
