  • Patent number: 10745071
    Abstract: A non-backdrivable passive balancing system for a single-axle dynamically balanced robotic device includes a body that includes a distal end and a proximal end, a controller module, and an actuator communicatively coupled to the controller module of the single-axle dynamically balanced robotic device. The actuator receives an engagement signal from the controller module, the engagement signal corresponding to an indication that the dynamically balanced robotic device is stationary, and the actuator causes the linkage to move the body from a disengaged position to an engaged position such that the distal end of the body contacts a ground surface and supports the dynamically balanced robotic device in a substantially upright position.

  • Patent number: 6734230
    Abstract: A procedure for the production of a modified acrylic sheet with high impact resistance, of the type in which a prepolymerization is done of a mix of monomers with a polymer of dissolved dienic monomers. The procedure is done in batches at low temperatures without there being a separation of the polymer of dienic monomers from the rest of the mix. The procedure facilitates obtaining a modified acrylic sheet with high impact resistance whose transmittance is kept after being subjected to an accelerated degradation, and whose impact properties are not reduced more than 50% after said accelerated degradation.
