Abstract: An anchor for securing a well tool can include a longitudinally extending central axis, an outwardly extendable grip member, and a mechanical linkage including multiple pivotably connected links. The links pivot relative to each other in a plane laterally offset from the central axis. A method of anchoring a well tool can include flowing a fluid through an anchor connected to the well tool, thereby outwardly extending a grip member into contact with a well surface, and applying a tensile force to the anchor, thereby increasingly biasing the grip member against the well surface and securing the well tool relative to the well surface. A method of anchoring a tubing cutter in a tubular string can include applying a tensile force from an anchor to the tubular string, and cutting the tubular string while the tensile force is applied from the anchor to the tubular string.

Abstract: Secure communication in mobile digital pages is provided. The system receives an electronic document and validates the electronic document for storage in a cache server. The system receives a request for the electronic document and provides it to a viewer component on a client computing device. The viewer component loads the electronic document in an iframe. The viewer component executes a runtime component to receive, via a secure communication channel, a tag from the electronic document. The system receives the tag and selects a data value for transmission to the viewer component. The viewer components provides the data value to cause the runtime component to execute an action with the data value.

Abstract: A device includes an optical assembly and a digital projector. The optical assembly is configured to receive visible scene light at a backside of the optical assembly and to direct the visible scene light on an optical path toward an eyeward side. The optical assembly includes a dimming layer disposed on the optical path. The dimming layer includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. The digital projector is disposed on the eyeward side of the optical assembly and is configured to selectively emit an activation light within the range of light wavelengths to activate a darkening of a region of the dimming layer to dim the visible scene light within the region.

Abstract: The present invention relates to a drum stencil printing system for reliably and automatically printing materials on the inside of a concave surface. The drum stencil printing system includes a pliable drum stencil secured in place by a stencil spring. As the printhead applies radial pressure to the drum stencil, the portion of the stencil in contact with the printhead is deflected to make contact with the container sidewall. When the printhead rotates, the portion of the stencil contacting the container sidewall also rotates to match the nozzle of the printhead. After printing is complete, the printhead retracts, and the pliable stencil is returned to its undeflected position, breaking contact between the stencil and the container, and protecting the printed material from being rubbed or worn off of the container.

Abstract: Toll advertisement messages (TAMs) are broadcast via V2X communication, each of the TAMs indicating geographic locations of lanes of a roadway for which tolls are due and cost information for traversing the lanes of the roadway. A tolling usage message (TUM) is received via the V2X communication, the TUM indicating, to a roadside unit (RSU), information regarding a vehicle entering one of the lanes of the roadway and a unique random account identifier to be used by the RSU to identify the vehicle. A toll receipt message (TRM) is broadcast via the V2X communication, the TRM including the unique random account identifier and indicating, to the vehicle, a final cost charged to the vehicle for access to the one of the lanes of the roadway.

Abstract: Learning to effectively imitate human teleoperators, even in unseen, dynamic environments is a promising path to greater autonomy, enabling robots to steadily acquire complex skills from supervision. Various motion generation techniques are described herein that are rooted in contraction theory and sum-of-squares programming for learning a dynamical systems control policy in the form of a polynomial vector field from a given set of demonstrations. Notably, this vector field is provably optimal for the problem of minimizing imitation loss while providing certain continuous-time guarantees on the induced imitation behavior. Techniques herein generalize to new initial and goal poses of the robot and can adapt in real time to dynamic obstacles during execution, with convergence to teleoperator behavior within a well-defined safety tube.

Abstract: A nesting equipment support pad is disclosed, in particular an outdoor air conditioner compressor pad. The pad comprises a parallelogram upper surface which contacts the compressor and descending side walls from each edge of the parallelogram upper surface. Two side walls include a notch to accommodate a matching notch of another identical support pad when placed in a nesting arrangement. These notched corners are at diagonally opposing corners of each pad permitting the nesting arrangements. Additional, support rib members and protrusions are located within the cavity formed by the four side walls to provide strength and rigidity. These rib members and protrusions are placed in an offset manner to permit the nesting arrangement without interference with the mating pad.

Abstract: A control device for a ceiling fan may have a motor drive circuit configured to control a rotational speed of a motor of the ceiling fan, an occupancy sensing circuit, and a control circuit configured to adjust the rotational speed of the motor in response to a detected occupancy or vacancy condition. The control circuit may process the signals generated by the occupancy sensing circuit to eliminate the effects of vibrations and/or wobbling of the ceiling fan. The control circuit may control the motor drive circuit to adjust the rotational speed of the motor in response to an accelerometer to minimize the magnitude of the wobble of the ceiling fan. The control circuit may be configured to learn a preferred rotational speed for the motor. The control circuit may also be configured to control the rotational speed of the motor to affect a thermal comfort level of an occupant.

Abstract: An erosion resistant composition includes a granular material and a wax including oil in which a weight percent of the oil in the wax is between 0.01-15%. The granular material includes a sand and has a first resistance to flow prior to being coated with the wax. The wax at least partially coats a portion of the granular material to form the erosion resistant composition which has a second resistance to flow after coating that is greater than the first resistance to flow prior to coating. The erosion resistant composition may be used, for example, in golf course bunkers or other landscaping applications. Related methods of making the erosion resistant composition are also described in which the granular material is dried, the wax is heated, and the granular material is blended with the melted wax.
