The connecting member has first end with a shape configured to mate with the first and second slots to permit the first end to slide into the first and second slots such that the connecting member extends out of the first slot and the second slot through openings in the first outer face and the second outer face.

Abstract: Systems and methods relating to magnetomicrometry and magnetic-target-based mechanomyography are provided. A method of detecting muscle activation, includes with a magnetic field sensor, detecting lateral vibration of a target implanted at a muscle or a tendon and estimating a level of muscle activation based on the detected lateral vibration. The target comprises a magnetic material.

Abstract: A security device can be provided to selectively restrict or prevent the opening of a sliding door, sliding window, or other sliding panel or other closure. For example, the security device can include a base plate that selectively engages a barricade member (or lock rail). While the barricade member is engaged with the base plate (in a locked state), the barricade member and base plate cooperate to restrict or prevent the sliding door, window, panel or other closure from moving to an open position (or moving out of a closed position). The barricade member can be moved relative to the base plate (to an unlocked state) to allow unrestricted movement of the sliding door, window, panel or other closure. The security device can include stop members that may restrict or prevent complete removal of the barricade member from the base plate.

The sensor assembly is configured to detect removal of the door-locking member from the slot of the storage container.

Abstract: A window cover may include a cover body, a mounting feature, a first roll-up-securing feature, a second roll-up-securing feature, a pull-strap, and a weight. The cover body can be moved between a rolled-up position and a deployed position. The mounting feature may be secured to a first side of the cover body and can attach the cover body above a window. The first roll-up-securing feature is secured to a second side of the cover body. The second roll-up-securing feature is secured to the first side of the cover body and is configured to engage the first roll-up-securing feature to retain the cover body in the rolled-up position. The pull-strap may be attached to the first side of the cover body and is accessible when the cover body is in the rolled-up position.

Abstract: A door security device can include a door member mounted to a swinging door, and a connector. The door member can include a slot having openings in at least one end and in an outer face. An end of a first leg of the connector can have a shape configured to mate with the first slot to permit the first leg to slide into the first slot such that the first leg extends out of the first slot through an opening in the outer face of the door member and such that a distal end of the second leg interferes with a surface of a door frame to prevent rotation of the swinging door relative to the door frame.

Abstract: The disclosed embodiment generate a 3D representation of a 2D scene depicted to two dimensional video. The 3D representation includes individual 3D media elements representing objects included in the 2D scene. 3D void segments within the 2D scene are identified based on an aggregation of the individual 3D media elements. The 3D void segments are prioritized for insertion of additional 3D media elements within the 3D void spaces based on a variety of factors including lighting present at the 3D void segment, a distance of the 3D void segment from a center of the 2D scene, a size of the 3D void segment, and a time duration the 3D void segment is present in the 2D scene. A new 3D media element in these selected for insertion into the 2D scene based on the priorities of the 3D void segments.

Abstract: A downhole drilling apparatus may comprise a rotatable body with fixed cutting elements protruding from an exterior thereof. To form a subterranean borehole, the fixed cutting elements, spaced at a constant radius from a rotational axis of the body, may degrade an earthen formation as the body rotates. The body may also have a rotatable cutting element protruding from its exterior. To remove material from an interior wall of the borehole, the rotatable cutting element may be positioned in a first rotational orientation wherein it extends radially beyond the constant radius of the fixed cutting elements. An amount of material being removed may be altered by rotating the rotatable cutting element into a second rotational orientation wherein it remains radially within the constant radius.
