Abstract: Systems and methods are described to identify motion events on a sloped surface, such as a mountainside, using transmitted and received radio frequency (RF) chirps. A one-dimensional array of receive antennas can be digitally beamformed to determine azimuth information of received reflected chirps. Elevation information can be determined based on time-of-flight measurements of received reflected chirps and known distances to locations on the sloped surface. Motion events may be characterized by deviations in return power levels and/or return phase shifts. The systems and methods may, for example, be used to provide real-time detection of avalanches and/or landslides.

The disk assembly further includes a hanger spindle supported relative to the distal end of the disk hanger for rotation about a first axis of rotation, and a blade spindle supported relative to the hanger spindle, with the blade spindle being rotatable about a second axis of rotation oriented non-parallel relative to the first axis of rotation. Additionally, the disk assembly includes a blade coupled to the blade spindle for rotation therewith about the second axis of rotation. Moreover, the disk assembly is configured such that rotation of the hanger spindle relative to the disk hanger about the first axis of rotation results in an adjustment of both an angle-of-engagement and a camber angle of the blade.

Abstract: A battery combiner having three power ports for interfacing with a DC power load and with two DC power batteries or other DC power sources. A conductive path interconnects the three power ports. A switching circuit includes a switch for each of the DC power battery ports with each switch operable by a controller to direct current flow between one battery and the DC power load while isolating the other battery from the other conductive path. Sensors corresponding with each power port sense voltage and/or current from each of the external devices. Data ports corresponding with each power port allow communication between the controller and smart external devices connected to the power ports. The battery combiner is operable to power the DC power load with one battery source until the battery source is depleted and to switch to the other battery source to power the load without interruption.
