Abstract: An actuation system for preventing actuation of a base device upon a non-target substrate. The actuation system includes a detector configured to generate and transmit a profile signal of a test substrate. A processing unit is in communication with the detector and configured to receive the profile signal of the test substrate from the detector, the processing unit being configured to determine whether the profile signal of the test substrate corresponds to a profile signal of a target substrate, and to generate an actuation signal if the profile signal of the test substrate corresponds to the profile signal of the target substrate. An actuation unit is in communication with the processing unit and the base device, the actuation unit being configured to receive the actuation signal from the processing unit and to permit the base device to actuate when receiving the actuation signal.

Abstract: Devices for controlling movement of aerial buckets via hydraulic systems. Each hydraulic system has valves that control movement of the aerial bucket. A control head of the device has a joystick that is moveable and encoders that detect movement of the joystick. A valve actuator manifold of the device is coupled between the control head and the hydraulic system and supports valve actuators moveably coupled to the valves. Servo drive systems supported by the valve actuator manifold are coupled to the valve actuators and are controllable to move the valve actuators. A processor module of the device is in communication with the encoders and the servo drive systems. The processor module controls the servo drive systems based on input from the encoders such that moving the joystick controls movement of the aerial bucket.

Abstract: A catheter for dilating occluded or stenotic blood vessels includes a collapsible filter device disposed between a dilating balloon and the distal end of the catheter. The collapsible filter device comprises a plurality of resilient ribs secured to the catheter at or adjacent the distal end thereof and extending generally axially toward the dilating balloon. Inflation of a filter balloon extends the ribs outward against the vessel wall to stretch filter material secured to the ribs across the vessel to form a cup shaped trap for fragments of a stenosis loosened by the dilating balloon. Upon deflation of the filter balloon, the resilient ribs retract against the catheter to retain the trapped fragments during withdrawal of the catheter. In the preferred embodiment, the ends of the ribs projecting generally toward the dilating balloon are secured to a ring which slides along the catheter. In use, the filter is extended and then the dilating balloon is inflated.
