Abstract: A charging stand is provided including a body having a first surface, and a bump having a top region and one or more sides. The one or more sides extend between the first surface and the top region. The charging stand further includes one or more base contact pins that are coupled to the body. Each base contact pin has an exposed end disposed at a first distance in a first direction from the first surface. The charging stand further includes a bump contact pin extending from the top region of the bump. The bump contact pin has an exposed end disposed a second distance in the first direction from the first surface, the second distance is greater than the first distance, and the first direction is perpendicular to the first surface.

Abstract: Systems and methods for conformal imaging vibrometry capable of real-time measurements of the dynamic motions of any arbitrary two-dimensional or three-dimensional structure. The systems and methods are able to fully characterize the dynamic behavior of an object of any arbitrary geometry. The test object is illuminated with multiple laser beams whose directions conform to the local normal axis of the surface. The approach enables high-speed vibration imaging of whole-body dynamics of arbitrarily shaped structures in real-time, with no multiplexed data capture or synthesized motion reconstruction, as is currently practiced. By measuring the object's vibrations simultaneously at multiple points, the disclosed systems and methods are able to reproduce the structural behavior under operational conditions, which can then be spectrally decomposed to determine the modal, complex modal and transient nature of the true structural dynamics.

Abstract: A voltage controlled oscillator comprising a substrate and a bilayer graphene transistor formed on the substrate. The transistor has two signal terminals and a gate terminal positioned in between the signal terminals. A voltage controlled PZT or MEMS capacitor is also formed on the substrate. The capacitor is electrically connected to the transistor gate terminal. At least one component is connected to the transistor and capacitor to form a resonant circuit.

Abstract: A digital communication system is disclosed, that allows a display of override content to interrupt a display of ongoing content on one or more display units. Ongoing content, such as advertisements, news, entertainment, or other relevant information, is provided on the display units until an urgent or security-related alert is required, and display of override content becomes necessary. Override content can include information relevant to the security of a passenger or passer-by viewing the display. Override content can relate to security threats such as accidents, major delays, fire, missing children, terrorist activity, or other content deemed adequately pertinent to warrant interrupting the display of ongoing content.

Abstract: An attachment for a percussive tool comprises a plurality of parallel rows of teeth (10) formed along the edges of planar chisel blades (9) arranged to form a shape having rotational symmetry. The attachment is connected to a percussive tool and placed in contact with a wall (12). The tool causes percussive action of the attachment such that the chisel blades (9) form a plurality of parallel grooves (13) and ridges in the wall. The tool and attachment are then rotated through an angle and placed in contact with the wall (12) in a position overlaying the plurality of parallel grooves (13). This breaks up the ridges forming a hole (15) of a substantially uniform depth. The attachment is used to produce square holes suitable for installing wall boxes for light switches or power points.
