Abstract: An optical element retainer includes a ring body defined about a central axis. The ring body includes an inner diametric surface, an outer diametric surface opposed to the inner diametric surface, a first annular axial surface, and a plurality of flexures extending from a second annular axial surface opposite the first annular axial surface.

Abstract: An imaging system includes a focal plane array including an array of pixels. An isothermal diaphragm covers a first portion of the pixels along a periphery of the array and exposing an imaging portion of the pixels. A controller is operatively connected to the focal plane array to read sensor data from the focal plane array, wherein the sensor data includes image data from the imaging portion of the pixels and non-uniformity data from the first portion of the pixels. The controller is operatively connected to the focal plane array to enhance the image data based on the non-uniformity data.

Abstract: A tube retainer can include a body configured to abut a face of a tube, a plurality of flexure flanges extending radially outwardly from the body and configured to flex relative to the body to provide a retaining force to the body when installed in a housing assembly around the tube, and a plurality of flexure legs axially extending from the body from a tube contact side of the body. At least a portion of the plurality of legs can include an inner diameter that is less than an outer diameter of the tube to provide a centering force to the tube.

Abstract: An adjustable butt stock adapter assembly may provide for vertical and rotational adjustment. A serrated plate may be positioned between an adapter with grooves for establishing a rotational position with the serrated plate, and a butt plate having serrations for establishing a vertical relationship with the serrated plate. The serrated plate may be operatively attached to a spring collar mounted in the adapter, such that pulling the serrated plate away from the collar and adapter overcomes the spring force and allows for adjustment of the rotational position. The butt plate may connect to the serrated plate through an engagement mechanism, such that disengaging the engagement mechanism allows for adjustment of the vertical position.

Abstract: Base units, systems and methods for wireless energy transfer are described. A wireless energy transfer system according to some examples includes a transmitter of wireless energy located within a communication device, such as a mobile phone, or attached to the communication device and a distance separated receiver located within an electronic wearable device other than the communication device, wherein the receiver is configured to receive wireless energy from the transmitter and convert the wireless energy into electrical power, which may be used to power the electronic wearable device.

Abstract: The present invention generally relates to integrating electronic components into an electro-active frame for driving electro-active focusing lenses. This is accomplished in a cosmetically pleasing manner that allows a platform of frame systems to be built from a single electronic module. Specifically, the present invention discloses controlling an electro-active lens in a deliberate, hands free manner that gives the user control of the electro-active lens.

Abstract: An agricultural combine with a plurality of grain tanks and an unloader system for unloading grain harvested by the combine. The unloader system has an unloader tube, a sensor and a controller. The unloader tube includes an interior passageway with a conveyor inside the interior passageway for moving the grain through the unloader tube and at least two discharge assemblies on the unloader tube for discharging grain traveling through the unloader tube to one of the plurality of grain tanks. The sensor is used for sensing an attribute of the grain that is to be unloaded through the unloader tube. The controller is operatively connected to and in communication with the unloader system and sensor so as to discharge the grain from the unloader tube through one of the at least two discharge assemblies based upon the attribute detected by the sensor.
