  • Publication number: 20190263413
    Abstract: A controller is provided for a vehicle having front and rear axles, each axle having two wheels, and first and second propulsion units. The controller controls the first and second propulsion units to generate a combined torque with reference to a total requested torque. The controller is configured to: receive a torque request signal; receive traction signals indicating available traction at at least one wheel; determine a traction torque range defined by a maximum and minimum torque for at least one of the at least first or second propulsion units in dependence on one or more of the traction signals; determine a proposed distribution of torque between each of the at least first and second propulsion units with reference to the total requested torque; and determine a proposed torque to be generated by each of the at least first and second propulsion units in dependence on the proposed distribution of torque.

  • Publication number: 20190230136
    Abstract: Systems and methods presented herein provide for real time communications between service provider subscribers. In one embodiment, a web server is operable to provide a network-to-network interface (NNI) with a plurality of service providers, to communicate with the service providers through WebRTC links, and to retrieve contact information of subscribers to the service providers over the WebRTC links. The web server also includes a database operable to store the contact information of the subscribers. The web server is also operable to process a connection request from a first of the subscribers to connect with a second of the subscribers, to retrieve the second subscriber's contact information from the database, to push a notification message to a device of the second subscriber using the second subscriber's contact information (e.g., a user identity), and to establish a WebRTC connection between first and second subscribers when the second subscriber accepts the connection.

  • Publication number: 20190223761
    Abstract: A method and apparatus for non-invasive assessment of lung inhomogeneity by accurate high temporal resolution measurement of respiratory gas flows at the mouth during steady state breathing and inert gas wash-in or wash-out and using these measurements to fit a mathematical model of the inhomogeneous lung. The model of the lung is based on modelling the lung as plural alveolar compartments each having an identical volume at functional residual capacity, but varying in its fractional share of total lung compliance, total pulmonary vascular conductance and total anatomical deadspace. A bivariate log-normal distribution of the lung compliance and pulmonary vascular conductance is used, together with a normal distribution of deadspace fraction.

  • Publication number: 20190167342
    Abstract: An electrosurgical forceps instrument in which an energy conveying structure for efficiently transferring electromagnetic energy (e.g. microwave energy and/or radiofrequency energy) from a coaxial cable to electrodes on the forceps jaws is incorporated into a compact jaw opening structure. The jaw opening structure may be dimensioned to be suitable for insertion down the instrument channel of a endoscope or other scoping device. Alternatively, the device may be configured as a laparoscopic device or be used in open procedures. The instrument may be used as a tool to perform new minimally invasive surgical techniques such as Natural Orifice Transluminal Endosurgery (NOTES) or the like.

  • Patent number: 10173136
    Abstract: Methods and systems described in this disclosure are directed at gamification. In some embodiments, the present disclosure relates to methods and systems for tracking actions taken by a user at predetermined gaming levels in a gaming application, the gaming application also facilitating users to interact with the gaming application in the form of questions and answers relating to topics in the military and armed forces. If the user is unable to provide a minimum number of correct responses to the questions presented, the gaming application displays actions that are to be performed by the user to continue playing the game. In some embodiments, a game is paused temporarily by a pause signal sent to the gaming application. The game resumes when a resume signal is sent to activate the gaming application.

  • Publication number: 20180311853
    Abstract: A high-speed food article slicing machine with a slicing station, a moveable frame supporting a food article feed mechanism frame, a food article gate, and a safety guard system for detecting an intrusion into the machine. Food articles are loaded onto a lift tray and raised to a staging position where food articles are in contact with a food article gate. The lift tray is located in line with the food article feed paths such that lateral shifting of food articles into the feed paths is not needed. Food article grippers, individually driven along feed paths by an overhead conveyor, move food articles over the food article gate towards the slicing station. The food article gate functions to assist in removal of food article end portions. The slicing machines utilizes a horizontally radiating laser intrusion detector to shut down systems when an unwanted intrusion is sensed.

  • Patent number: 9441493
    Abstract: A fixture having a foot clamp for clamping a foot of an aerofoil and a tip clamp for clamping a tip of the aerofoil is provided with an array of supports between the foot clamp and the tip clamp. Each support within the array is independently addressable to one of the aerofoil flanks when the aerofoil is secured to the fixture. The support is driven by pneumatics till it contacts the aerofoil when it is locked by an alternative mechanism.

  • Patent number: 8973516
    Abstract: The audible alarm device comprises a coupling assembly, a chamber assembly and an air horn assembly, releasably separable from each other. The coupling assembly and the chamber assembly are movable by squeezing action so that in one relative position pressurized air from an air inlet in the coupling assembly is allowed through a valve assembly into an interior chamber in the chamber assembly, the air driving a bi-stable piston into repeated contact with a percussion diaphragm, producing a below surface audible sound. An exhaust passage permits air to pass from the interior chamber to the surrounding environment. When the coupling assembly and the chamber assembly are moved by diver action to a second relative position, the exhaust passage is blocked, forcing air in the interior chamber to exhaust to the air horn assembly, which produces an audible sound above the water surface.
