A drive control device for a brushless motor includes a full-wave rectifying-filtering circuit, a voltage regulating circuit, a drive control circuit and a protection circuit. A combination of the rectifying-filtering and voltage regulating circuit provides both the motor coil and the drive control circuit capable of operating at a normal working status to ensure the brushless motor with safe and reliable operation. Therefore, the brushless motor does not need a bulk and complex transformer for voltage drop, which may reduce the reliability of the operation.

A medical device, and related method, use epicardial ablators and detectors for intraoperative epicardial approaches to ablation therapy of cardiac conduction pathways. An epicardial gripper is sized to grasp the cardiac circumference or smaller structures on the epicardial surface of the heart. Ablators are disposed on the arms of the gripper for epicardial ablation of cardiac conduction tissue. In another embodiment of the invention, an electrode system includes a flexible, adjustable probe forming a loop for epicardial ablation. Ablators are provided on one or multiple surfaces of the probe for epicardial ablation of cardiac conduction tissue. In yet another embodiment of the invention, an endocardial ablator detection system provides an indicator adjacent an ablator on an endocardial catheter, and a detector on an epicardial probe. The epicardial probe detects signals transmitted by the indicator on the endocardial catheter to localize the position of the endocardial ablator relative to the epicardial surface. The surgeon uses this information for guidance in adjusting the position of the endocardial ablator according to therapeutic objectives of cardiac ablation.

A device completely disposable within a bodily lumen of a patient and for controlling flow through the bodily lumen having a device body having a proximal end, a distal end and a device lumen within the device body extending from the proximal end to the distal end and a fixation element extending from the outer wall of device body adapted and configured to engage with the wall of the bodily lumen. The device body is adapted and configured to move from a position where the device lumen blocks flow through the bodily lumen to a position where the device lumen allows flow through the bodily lumen. In other configurations, there are one or more valves within the device lumen adapted and configured to move between a position to block flow through the bodily lumen and a position to allow flow through the bodily lumen. There is also a method for implanting a device within a body lumen by placing a device having a device body and fixation elements extending from the device body on a catheter and then dilating the body lumen such that the device body and the fixation elements may advance through the dilated body lumen without the fixation elements engaging the wall of the body lumen. Next, advancing the device to an implant site within the body lumen and then engaging the walls of the body lumen with the fixation elements.

A method and apparatus is provided for cryogenically ablating a predetermined portion of tissue in the body of a patient. Cryoablation is accomplished by a cryoblation catheter having a hollow shaft insertable into the blood vessel of a patient. The shaft has a closed tip portion and a fluid flow passage for directing a flow of cryogenic fluid to the tip. Cryogenic cooling is effected by a liquid-to-gas fluid phase change adjacent the catheter tip. Electrical signal activity may be monitored by an electrode formed integral with the tip to confirm treatment of the paper tissue site.

A portable door locking system includes a door that is hingedly positioned in a door jamb and the door includes a hinge. A locking unit is provided and the locking unit is selectively coupled to the hinge. The locking unit extends laterally between the door and the door jamb. In this way the door abuts the locking unit when the door is urged into an open position. The locking unit inhibits the door from being opened to inhibit an intruder from entering the room.

A music recommendation method may include obtaining the music belongingness function of music, which is the set of granularity of music in different dimensions, wherein the dimension is the classification of music and the granularity is the classification of the dimension; obtaining the user belongingness function of a user, which is the set of granularity indicating likes of user in different dimensions; calculating a granularity correlation function by using the music belongingness function and the user belongingness function; calculating the value of the probability function indicating likes of user for music by using the granularity correlation function and a dimension weighting coefficient; and recommending the music to the user when the value of the probability function indicating likes of user for music is greater than a preset threshold. An apparatus applying to the method comprises corresponding modules.

The connector of the present invention includes a base having a plurality of terminals for contacting the card and a cover for holding the card. In an embodiment, the base has two resilient plates extending from the base, each of the plates has a distal end at which an inner hinging portion is formed. The cover has an outer hinging portion engaged with the inner hinging portions to form a hinge such that the cover is pivotally mounted on the base and movable in relation to the base. Each of the resilient plates is L-shaped such that the hinge is deflectable from the base.
