  • Patent number: 11696643
    Abstract: Stabilizer for a piece of furniture, such as a dresser or television, includes an elongate preferably rigid portion having opposed ends, two plates each having an inner major surface and an outer planar surface on a side opposite the inner major surface, a respective hinge that pivotally connects each end of the elongate portion to the inner major surface of a respective plate, and attachment structure arranged at least partly on the outer planar surface of each plate for attaching the plate to the piece of furniture or to a vertical support surface behind the piece of furniture. When the stabilizer is attached to the piece of furniture at a location above the location at which the stabilizer is attached to the vertical support surface and the stabilizer is in a vertical orientation, the stabilizer provides resistance to tipping of the piece of furniture away from the vertical support surface.

  • Patent number: 11391349
    Abstract: A compact angular actuator allows for angular displacement between a first section and a second section. The first section comprises a cam that is circular in cross section and has a wedge-shaped face. The second section comprises two or more constraint components that are in contact with the face of the cam. A hinge joins the first section and the second section in proximity with one another. As the cam is rotated about an axis that is perpendicular to and extends through a center of the circular cross section, the position on the face that the constraint components are in contact with changes. As a result, a force is imparted between the first section and the second section, changing the angular displacement between the two. The actuator fits within a compact volume and allows for precise controlled angular displacement, while allowing that displacement to be maintained without power consumption.

    Abstract: A multi-axis gimbal has each axis defined by a respective spherical shell driven by a flat, compact motor attached to the driven shell and to a next outer shell (or to an external mounting platform, in the case of the outermost shell). The shells rotate about respective axes. In one configuration, the outermost shell is referred to as the “azimuth” shell because in use it rotates about a vertical axis. The next inner shell is an elevation shell that rotates about a first horizontal axis that is orthogonal to the axis of the camera or other sensor payload. An optional third shell can be used to provide “roll” motion, such as rotating a camera about its axis to obtain a particular rotational orientation with respect to a target.
