Abstract: A sander includes a housing defining a front end and a rear end relative to a direction of travel of the sander on a work surface, an actuator, and a battery platform. The housing supports a motor and has a grip disposed over the motor adjacent the front end and a handle positioned at or adjacent the rear end. The housing further supports a belt drive assembly configured to rotatably support a belt and having a belt plate extending a long a first plane. The actuator is supported by the handle. The battery platform is at least partially supported by and located above the handle. The battery platform defines a battery pack receptacle configured to support a battery pack. The battery platform is oriented along a second plane orientated at an acute angle relative to the first plane.

Abstract: Illustrative embodiments are directed to methods, apparatus and computer program products for segmentation of X-ray tomography images via multiple reconstructions. A computed tomography scan of an object is received. The computed tomography scan is processed to generate an absorption reconstruction and a phase reconstruction from the computed tomography scan. First and second sets of seeds within the phase reconstruction are labeled as corresponding to a first phase by thresholding below a first threshold and corresponding to a second phase by thresholding above a second threshold, respectively. The absorption reconstruction is segmented automatically using an algorithm based on the first set of seeds, the second set of seeds and the absorption reconstruction. A final segmentation is produced based on a combination of the absorption reconstruction and the phase reconstruction.

Abstract: A grill cover that fits over or is positioned over high frequency acoustical regions and low frequency acoustical regions of a playback device. A portion of the grill cover that fits over or is positioned over a high frequency acoustical region has small area openings and a portion of the grill over a low frequency acoustical region has large area openings. In portions of the grill cover between the portions over high and low frequency acoustical regions, the openings may have an intermediate area to visually blur the differences between the portions of the grill covers. To further blur the differences, the differently sized openings may be interleaved.

Abstract: A method of promoting growth in a photosynthetic organism comprising treating the photosynthetic organism with a metal complex or a precursor thereof, wherein the metal complex comprises a metal selected from the group consisting of zinc (Zn), cobalt (Co), copper (Cu), nickel (Ni) and iron (Fe), and a ligand, which is a bidentate or tridentate ligand. Metal complexes and their ligands are also described.

Abstract: A method of adjusting the closing force of a door coupled to a door closer assembly having a bias element. The method includes determining the kinetic energy of the door without using the weight or other dimensions of the door. The determined kinetic energy is used to adjust the closing force of an electro-mechanical door closer that includes a spring and a motor. The door includes the use of one, some of, or all of an accelerometer, an angular position sensor, a time to close, a breaking torque, and a controller to identify values a acceleration, velocity, and/or position of the door. The identified values are provided to the controller, which is configured to calculate the kinetic energy of the door. The calculated kinetic energy is used to determine the closing velocity of the door closure to ensure proper operation of the door at the point of installation.

Abstract: An exemplary method relates to determining an open/closed position of a door. The method generally involves generating, by a multi-axis magnetometer mounted to the door, a plurality of signals relating a magnetic field having a net magnetic flux point, and generating, by a controller and based on the plurality of signals, a current incidence angle defined between the multi-axis magnetometer and the net magnetic flux point. The method further includes comparing the current incidence angle to a known incidence angle, wherein the known incidence angle is defined between the multi-axis magnetometer and the net magnetic flux point when the door is in a known position. The method further includes determining the open/closed position of the door based on the comparison of the current incidence angle to the known incidence angle.
