Additionally, the method comprises determining, by at least one processor, a location of the passive transponder(s) based on the response signal(s). Further, the method comprises determining, by the processor(s), whether the passive transponder(s) is located within a threshold distance away from machinery by using the location of the passive transponder(s).

Abstract: A signaling device that provides for passive radar detection. An incoming radar signal is reflected back outward away from the device with increased power. The incoming radar signal can also power a harmonic transceiver and generate a harmonic signal that is transmitted outward away from the device. The signaling device can also include one or more powered components to further transmit an outgoing signal.

The method includes moving a probe at least partially through the bore in a first lineal direction about the bore axis while simultaneously rotating the probe about the bore axis. The probe includes a contact element contacting the surface of the bore at a plurality of first contact points as the probe moves in the first lineal direction.

Abstract: Provided is cutting tool. The tool, in certain examples, includes a drill body that defines a drill axis, and a tool window formed in the drill body. The tool also includes a drill bit extending from the drill body, and a material reworking attachment (“MRA”) coupled to the drill body and storable within the tool window. The MRA is extendable from a stored position into either a surface-finishing position or a material-removal position. The MRA includes a first chamfering blade, a second chamfering blade, and a finishing surface interposed between the chamfering blades. The tool also includes a position manager to detect a position of the cutting tool with reference to a workpiece, and an actuator to transition the MRA from the stored position to the material-removal position, followed by a transition to the surface-finishing position, and followed by a transition to material-removal position.

Abstract: An apparatus for locational aiming of an overhead directional service unit includes a body including a first end configured to be matingly engaged with a housing assembly of the overhead directional service unit and a second end longitudinally opposed to the first end. A light source is disposed within the body and operable to project a light beam from the second end in a direction defined by a longitudinal axis of the body. With the first end matingly engaged with the housing assembly, pivotal movement of the body about a pivot axis relative to a mounting assembly of the overhead directional service unit applies a leverage force to the housing assembly to pivotally reposition the housing assembly relative to the mounting assembly so that the housing assembly is directionally aimed toward a target location visually indicated by the light beam.

Abstract: A method and system for displaying an image on a liquid crystal display (LCD) that may reduce power consumption. The method and system can include calculating a luminance for pixels in an image in a LCD based upon a light spread function and brightness values of light emitting diodes (LEDs). The method and system can also include changing a brightness of an LED based upon a consideration of the gray value of the pixels and the distance of the pixels from a dominant LED. The method and system can further set the brightness of the LED units to a brightness substantially greater than or equal to a gray value of each pixel of the image.
