摘要:
A system for controlling sand has an expandable screen an an inner string to isolate the sand screen allowing for drilling fluids to be circulated to the bottom of the drilling assembly, before returning up the annulus in normal fashion. Both ends of the expandable screen are mount on an inner string. The inner string is integral with the internals of the bottomhole drilling assembly, allowing for retrieval thereof, including a pilot bit. Upon retrieval an isolation valve will close and seal thus providing sand control integrity in the well. Release from the sand screen will be by pumping a ball down the string and engaging this in a catcher to slim the sliding sleeve open, giving hydraulic access to the liner hanger and engaging slips in the previous casing. Further pressure will release the ball into a catcher, restoring communication through the drill string.

A flexible manufacturing line and manufacturing process employs an overhead gantry system to transfer fixtured workpieces between machining stations served by the gantry system. The machining stations include CNC machines, turret cells, and/or dedicated machines which receive the fixtured workpieces through top-entry openings. The invention provides flexibility and adaptability to variation, improved maintenance of reference position on the fixture during manufacture, improved accessibility to machining stations during operation, and increased safety.

A modem to select a data transfer protocol based at least in part on conditions of the computing environment in which the modem is implemented. The modem includes means for monitoring the system processing load and selecting modem technologies and bit rates which are appropriate for current and anticipated system loading. The modem can determine system loading from measurements of microprocessor utilization in various execution contexts and can select a technology and bit rate which meets modem data transfer requirements while minimizing utilization during peak system loading.

The present disclosure includes, systems, methods, and devices provided for transporting produce from at least one row of plants to a distribution location in a field including a frame for carrying the picked produce from the at least one row of plants, at least three wheels coupled to the frame, at least one motor coupled to at least one of the wheels, a power unit connected to the frame, at least one proximity sensor coupled to both the front side and back side of the frame to identify movement of the human, and a control unit connected to the frame and coupled between the motor, at least one sensor, and the power unit to autonomously move the transport when the sensors identify a predefined condition in the field.
摘要:
The present invention relates to a control arrangement for controlling an atmosphere generating device, comprising a control device (102) having a control surface (110), and a control object (104, 106) adapted to be freely-positioned onto the control surface, the control object comprising identification means (116), wherein the control device comprises a control unit (114) adapted to identify the control object, to receive relative positioning information from the control surface relating to the positioning of the control object, and to output control data corresponding to the placement information for controlling the atmosphere generating device. By means of the invention it is provided an intuitive user interface in which the user is provided with a flexible solution in which not only repositioning of the control object onto the surface of the control device influence the atmosphere, but also the identity of the control object.

The present invention relates to a control device for providing a recommendation for at least one physical environment for an activity and for providing a recommendation for at least one activity in a physical environment. Such a control device is suitable for users working in flexible office environments and can thus be used for easily locating spaces that suit the users' needs for the current work task. Using historical data mined from embedded sensors in the offices in conjunction with a user's preferences as to how he likes a location to be, a suitability rating can be generated in real time. This enables users to find locations that can suit not only their tangible needs (i.e. luminaires, furniture, equipment, windows etc.) but also their intangible and personal needs (i.e. temperature, light level, busyness, noise levels, humidity, activity etc.).

In certain embodiments, a system is provided for measuring page-specific user feedback concerning each of a plurality of particular web pages. A user-selectable element is viewable on and solicits page-specific user feedback concerning each such web page upon initial display of the web page, the element appearing identically and behaving consistently on each such web page. Software associated with the element is operable to receive the feedback concerning the web page for reporting, the feedback comprising one or more page-specific subjective ratings of the web page and one or more associated page-specific open-ended comments concerning the web page, the feedback allowing an interested party to access page-specific subjective ratings and associated page-specific open-ended comments across the plurality of web pages to identify one or more web pages for which the feedback is notable.
摘要:
An apparatus and a method for discriminating between tachycardias of physiological origin, and those of pathological origin having similar atrial and ventricular rates, are disclosed. The apparatus includes two sensing electrodes for registering the electrograms from the atrium and the ventricle of the heart. There is further included a signal processing element for determining the times of atrial and ventricular events, and an algorithm for classifying the heart rhythm. The algorithm includes a means for discriminating between different types of heart rhythms having overlapping ventricular rates and having similar atrial and ventricular rates. The method utilizes an analysis of the relationships between successive atrial and ventricular intervals (i.e., atrial-atrial (AA), ventricular-ventricular (VV) and atrial-ventricular (AV) intervals) in discriminating between such heart rhythms.
