Abstract: Devices, assemblies, systems, and methods are disclosed for stabilizing a cart. An example cart is a surgical cart having a robotic arm thereon. A stabilizer system may be part of or used with the cart to stabilize the cart at a location. The stabilizer system may include a stabilizer and an actuator. The stabilizer may have a foot and a biaser configured to bias the foot to a retracted position and contribute to an amount of force applied to a floor supporting the cart when the foot is in a deployed position. The actuator acts on the stabilizer to overcome a bias force biasing the stabilizer to the retracted position and cause feet of the stabilizer to contact the floor. Once the feet of the stabilizer contact the floor, a spring of the biaser causes the foot to apply a predetermined force amount to the floor.

The translatable shaft includes a body that extends at least from a pen-interfacing portion in the pen-receiving cavity to a switch-interfacing portion thereof.

Abstract: Photoactive compounds are disclosed. The disclosed compounds can exhibit molecular structural elements tending to increase the evaporability of the compounds, such as by including geometric core disruption by use of conformationally restricted side groups instead of freely rotatable side groups or use of indandione moieties instead of dicyanomethyleneindanone moieties. The disclosed photoactive compounds include those with an imine-bridging linking moiety, which can shift the optical properties to a more red-shifted absorbance as compared to compounds with an alkene-bridging linking moiety. The disclosed photoactive compounds can be used in organic photovoltaic devices, such as visibly transparent or opaque photovoltaic devices.

Abstract: Assemblies, systems, and methods are directed at a neuromonitoring bone drill bit. The assembly may include a surgical bone drill bit, a neuromonitoring connection in electrical communication with the drill bit, and a shield extending over a distal end of the drill bit. The shield may be configured to withdraw proximally as the drill bit is advanced into a subject's bone. The assembly may be connected to a surgical drill and used in a surgical spinal procedure. In operation, the assembly may be advanced to a subject's bone at a surgical site and the drill bit may rotate into the subject's bone. In response, the shield may engage the bone and the drill bit may be advanced with respect to the shield. The shield may electrically insulate tissue from electrical current passing through the drill bit as it is inserted at the surgical site.
