Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

Abstract: Contaminate-sequestering coatings including a network of hydrolyzed silane compounds including a plurality of thiol functional groups, a plurality of fluorinated functionalities, or both are provided. The contaminate-sequestering coatings may sequester one or more per- and polyfluoroalkyl substances (PFAS), heavy metals, biological species or any combination thereof. Methods of functionalizing a substrate surface with contaminate-sequestering functionalities that sequester one or more PFAS, heavy metals, or both are also provided. Methods of removing contaminants from contaminate-containing liquids, and devices including the contaminate-sequestering coatings are also provided.

Abstract: A plurality of golf balls are stored in a canister from which they are received by a vertical supply tube that supports the canister. From the tube, the balls move into a delivery arm that carries a release mechanism on its outer end. Actuation of the release mechanism when the arm is in its delivery position causes a ball to be dispensed onto a tee. The arm, which is supported by a sleeve surrounding the supply tube, can then be rotated about a vertical axis until it extends rearwardly and out of the way in a rest position. The supply tube is provided with openings with which the arm can be aligned on either side so that the apparatus can be operated in a right- or left- handed mode.
