Abstract: A robot includes a mobile base, a turntable rotatably coupled to the mobile base, a robotic arm operatively coupled to the turntable, and at least one directional sensor. An orientation of the at least one directional sensor is independently controllable. A method of controlling a robotic arm includes controlling a state of a mobile base and controlling a state of a robotic arm coupled to the mobile base, based, at least in part, on the state of the mobile base.

Abstract: A mat includes a mat body defining an upper surface dimensioned for a user to stand on the upper surface. The upper surface is non-planar and includes at least one terrain feature defining the non-planarity. The terrain feature has a size that is on the order of magnitude of the size of the user's foot. Presenting this surface to the user may help remind him or her to move his or her feet to thereby adopt multiple poses, thereby preventing the user from maintaining any single pose for a fatigue-inducing duration.

The shape formed from the first and second sides provides an aerofoil profile of the door. The invention also provides an aircraft landing gear arrangement 100, an aircraft 1000, methods of operating an aircraft and a method of reducing noise.

Abstract: An interface system generates interfaces for visualizing human-machine interactions including piping systems. The interface system receives, as input, parameters describing a first pipe data object and a second pipe data object. The pipe data objects can be diagrams representing physical piping in an industrial system. Using the parameters of the first and second pipe data objects, the system determines whether images of the pipes in the interface will overlap. When the system renders vector graphic images of the first pipe data object and the second pipe data object, the second pipe data object is rendered with markings that provide a visual indication that the two pipes overlap and are not connected. The interface system further enables a user to edit the piping diagram to combine the first and second pipe data objects into a single combined pipe data object and updates the rendered images for display.

Abstract: A desktop includes a first portion, a second portion, and a linkage assembly attached to the first and second portions. The first desktop portion has a first, substantially planar, upper surface, and an edge. The second desktop portion has a second, substantially planar, upper surface, a proximal edge, and a distal edge. The linkage assembly is configured such that the second desktop portion is movable between a first configuration and a second configuration. At the first configuration, the second desktop portion is substantially coplanar with the first desktop portion, and the proximal edge of the second desktop portion is adjacent the edge of the first desktop portion. At the second configuration, the proximal edge of the second desktop portion is beneath the edge of the first desktop portion, and the second desktop portion is not coplanar with the first desktop portion and is not parallel to the first desktop portion.

Abstract: Methods and apparatus for the study of gastrointestinal transit in a human or animal subject. The method being for the study of a subject which has previously ingested a container containing first and second fluids that are detectable and distinguishable by MRI, which method comprises the steps of forming a first magnetic resonance image of at least a portion of the subject's GI tract in which the container is located, wherein the magnetizations of the first and second fluids are in-phase; forming a second magnetic resonance image, coincident with the first image, wherein the magnetizations of the first and second fluids are out-of-phase; and subtracting the second image from the first image, or vice versa, to form a composite image.

Abstract: A multiple stage synthesis gas generation system is disclosed including a high radiant heat flux reactor, a gasifier reactor control system, and a Steam Methane Reformer (SMR) reactor. The SMR reactor is in parallel and cooperates with the high radiant heat flux reactor to produce a high quality syngas mixture for MeOH synthesis. The resultant products from the two reactors may be used for the MeOH synthesis. The SMR provides hydrogen rich syngas to be mixed with the potentially carbon monoxide rich syngas from the high radiant heat flux reactor. The combination of syngas component streams from the two reactors can provide the required hydrogen to carbon monoxide ratio for methanol synthesis. The SMR reactor control system and a gasifier reactor control system interact to produce a high quality syngas mixture for the MeOH synthesis.

Abstract: An electric power generation system may be constructed of multiple similar generator modules arranged between a rotor and a stator. The rotor may be coupled to and/or integrated with a turbine that is configured to rotate in the presence of a fluid stream such as wind or water. Each generator module may have a rotor portion configured to generate a magnetic field having at least one characteristic that changes with respect to the rotational speed of the rotor. Each generator module may further have a stator portion configured to generate an alternating electric current responsive to the magnetic field. The generated electric current may be controlled by the stator portion of the generator module in order to magnetically control the rotational speed of the rotor and the turbine. Separation between the rotor and stator portions of the generator module may be magnetically maintained.
