Application number: 20140271269
Abstract: This disclosure proposes designs for a fan shroud that dissipates thermal energy from a motor using a single, externally-powered fan design. Examples of the proposed fan shroud allow the cooling fluid to achieve maximum velocity at a position at which the fan shroud exposes the flow to cooler ambient air that surrounds the fan shroud/motor assembly. In this configuration, the high-velocity cooling fluid draws the cooler ambient air towards the surface of the motor, which, in turn, increases the thermal capacity of the moving cooling fluid to dissipate more thermal energy from the motor.

Application number: 20140277678
Abstract: Certain examples provide systems, methods, and apparatus for patient care and support. An example three-dimensional printed model of a portion of a patient anatomy is to be formed for the patient based on image data obtained of the patient. The three-dimensional printed model includes an output device to provide an output from the three-dimensional printed model that is perceptible to the patient. The three-dimensional printed model includes a communication device to facilitate exchange of information between the three-dimensional printed model and one or more external systems. The three-dimensional printed model includes a controller to facilitate exchange of information, via the communication device, between the three-dimensional printed model and the one or more external systems. The controller is also to provide feedback to the patient via the output device with respect to a condition affecting the portion of the patient anatomy represented by the three-dimensional printed model via the output device.

Application number: 20140265942
Abstract: An apparatus includes at least one energy source and a drive system coupled to the at least one energy source. The drive system converts electrical power received from the at least one energy source and provides converted electrical power for driving at least one load. The drive system includes a first converter, a second converter, and a first switch module coupled to outputs of the first and second converters. When the apparatus is operating under a first mode, the first switch module is switched to assume a first state to allow a first output electrical power provided from the first converter and a second output electrical power provided from the second converter to be combined for driving a first load with the combined output electrical power.

Application number: 20140268638
Abstract: A light emitting apparatus comprises: an LED-based light source; a spherical, spheroidal, or toroidal diffuser generating a Lambertian light intensity distribution output at any point on the diffuser surface responsive to illumination inside the diffuser; and a base including a base connector. The LED based light source, the diffuser, and the base are secured together as a unitary LED lamp installable in a lighting socket by connecting the base connector with the lighting socket. The diffuser is shaped and arranged respective to the LED based light source in the unitary LED lamp to conform with an isolux surface of the LED based light source. The base is operatively connected with the LED based light source in the unitary LED lamp to electrically power the LED based light source using electrical power received at the base connector.

Application number: 20140259669
Abstract: A system for installing a blade insert between a root portion and a tip portion of a rotor blade of a wind turbine is disclosed. The system may include a root cradle assembly configured to support the root portion of the rotor blade and a tip cradle assembly configured to support the tip portion of the rotor blade. At least one of the tip cradle assembly or the root cradle assembly may be movable relative to the other of the tip cradle assembly or the root cradle assembly to allow the tip portion to be spaced apart from the root portion after the rotor blade has been divided between the root and tip portions. In addition, the system may include an insert cradle assembly configured to support a blade insert for the rotor blade. The insert cradle assembly may be configured to be positioned between the root cradle assembly and the tip cradle assembly so as to position the blade insert between the root portion and the tip portion.

Application number: 20140270059
Abstract: Embodiments of the systems and methods of this disclosure utilize different positions, or poses, of a target object to collect images that can result in high-resolution volumetric models of the target object. In one embodiment, the object poses define a lateral position and an axial position (also “angular orientation”) of the target object relative to components of an imaging system, e.g., the source of the x-ray beam. The imaging system captures an image of the target object in the object poses. Further processing of the image data that relates to the images generates a volumetric model of the target object at higher resolution, or with fewer artifacts, as compared to similar volumetric models that arise from conventional scanning of these large parts.

Patent number: 8839101
Abstract: Aspects of the invention provide a tool for configuring software for an electric meter. A parameters table having values for the electric meter in a platform independent format is created. The table is then merged with to a mapping table that is configured specifically to the particular model of the electric meter to be configured to form a build table that can be executed on the electric meter. The build table is then installed on the electric meter.
