摘要： Radio Frequency (RF) transmitter adaptors, methods and articles of manufacture are disclosed. A method of adapting an RF transmitter for using in controlling a radio controlled (R/C) device having an RF receiver includes receiving a pulse-position modulation (PPM) signal from the RF transmitter, automatically selecting a channel assignment map based on the PPM signal, and generating, from the PPM signal, an RF communication signal compatible with the RF receiver for use in controlling the R/C device based on the selected channel assignment map.

摘要： A ramp assembly provides a transition surface from a vehicle interior to an alighting surface. The ramp assembly includes a ramp portion that rotates between a stowed position and a deployed position. A panel is coupled to the ramp portion about a first axis. The ramp assembly further includes a linkage that is coupled to the ramp portion. An actuator is coupled to the linkage to move the ramp portion through a deployment motion. The deployment motion includes a first phase during which the linkage rotates the ramp portion about the first axis. During a second phase of the deployment motion, the linkage moves the first axis from a raised position to a lowered position.

During charging state in excess of two Amps of current can be provided to each device connected to the hub. Each USB port circuit includes a power FET to selectively provide current to the USB port according to the state of the hub. Current sensors on each of the USB ports detects an amount of current being drawn by a device connected to the USB port. Each USB port is provided with indicators to indicate the charged state of the device connected to that port. The charge state of the device is also provided to the microcontroller which provides a summary status indication of the set of devices connected to the USB hub.

摘要： A catheter is disclosed that has a detachable tip for delivery of a therapeutic substance to a chronic total occlusion (CTO) within a body vessel. The tip is made from a biodegradable material and includes an active agent dispersed therethrough. The detachable tip pierces into the calcified lesion, detaches from the catheter, and remains embedded within the lesion as the tip degrades, thereby releasing the active agent. The active agent is a therapeutic substance effective to treat of a CTO. The active agent may be a drug, an enzyme, bacteria, or a parasite that degrades or softens the calcified lesion.

摘要： The present invention provides a method and an apparatus for reducing aspect ratio dependent etching that is observed when plasma etching deep trenches in a semiconductor substrate through an alternating deposition/etch process. A plurality of different sized features on the substrate are monitored in real time during the alternating deposition/etch process. Then, based on the information received from the monitor, at least one process parameter is adjusted in the alternating deposition/etch process to achieve equivalent etch depths of at least two different sized features on the substrate.

摘要： A ramp assembly includes a ramp portion configured for reciprocating motion between a stowed position, a deployed position, and a neutral position. The ramp assembly further includes a counterbalance that provides a force to bias the ramp portion toward the stowed position when the ramp portion is between the deployed position and the neutral position, and toward the deployed position when the ramp portion is between the stowed position and the neutral position. A shaft rotates in a first direction when the ramp portion moves toward the stowed position, and in a second direction opposite the first direction when the ramp portion moves toward the deployed position. A crank is fixedly coupled to the shaft. A rod is rotatably coupled at a first end to the crank about a first axis and at a second end to a cylinder. The cylinder is coupled for rotational movement about a second axis.

摘要： A counterbalanced ramp assembly includes a ramp portion coupled for reciprocating motion between a stowed position, a deployed position, and a neutral position. First and second elements are operatively coupled to the ramp portion. When the ramp portion moves from the neutral position toward the deployed position, the first element moves a first end of a spring toward a second end of the spring as the second end of the spring maintains a fixed position. When the ramp portion moves from the neutral position toward the stowed position, the second element moves the second end of the spring toward the first end of the spring as the first end of the spring maintains a fixed position.
