    摘要: A music generator having a memory unit to store time and tone data of the selected song, which are read out successively from the memory unit in response to address signals applied to the memory unit by an address counter. The time data are sent to a latch, and the tone data are sent to a programmable counter and converted into a waveform by a wave shaping circuit. A tempo generator is electrically connected to, and actuates, a timing generator. The timing generator sends clock signals to the multiplexer when playing the selected song. Depending on the time data stored in the latch, the multiplexer determines and decides whether or not to actuate the address counter for requesting for the next tone data stored in the memory unit.

    摘要: A wheeled vehicle comprising a power-driven spider assembly for ascending and descending stairs. The vehicle includes an angular position sensor providing input to a controller operable to control a servo-motor to effectively lock the position of the spider relative to the frame, regardless of the hand truck's spatial orientation relative to a vertical plane, or any balancing of the hand truck. The angular position sensor provides input to the controller, which is programmed with predefined angular zones of instability, and causes the controller to accelerate rotation of the spiders through those zones when the wheeled vehicle is in the descent mode, to avoid instability of the hand truck. A hand truck may include a removable basket and/or a pivotable platform usable to transport loads.

    摘要: An ablation catheter is provided for ablating internal tissue of a patient. The catheter includes a distal end that is adapted to be inserted into a body cavity relative to a desired location therein (e.g., within the heart). An ablation electrode is connected relative to the distal end of the catheter for providing ablation energy to patient tissue. A heat sink is provided that is in thermal contact with the ablation electrode. The heat sink, in addition to being in thermal contact with the ablation electrode, is electrically isolated from the ablation electrode. This allows the heat sink to conduct heat away from the ablation electrode without dissipating electrical energy from the electrode. In this regard, the heat sink may prevent build-up of excess heat within the electrode that may result in blood coagulation and/or tissue charring.
