摘要:
Systems and methods of detecting position and movement of the bladder and urethra are provided. In one embodiment, a system is provided including a flexible tube, or catheter, with one or more MEMS sensors and an RF antenna embedded thereon; and an RF receiver located external to the flexible tube. The sensors in the flexible tube can be connected to external electronics, which are in turn connected to a computing device. The MEMS sensors provide motion detection and the RF sensors provide position/distance detection. The MEMS sensors can include, but are not limited to, one or more accelerometers, gyroscopes, stress sensors, tilt sensors, and/or pressure sensors. In operation, the flexible tube is inserted into the bladder through the urethra to detect the location of the bladder neck and track the motion and/or shape of the urethra. The results of the tracking can be provided on a display.
摘要:
Embodiments of the subject invention relate to a method and apparatus for stabilizing a moveable element of a device. In an embodiment, a device is provided including a base, an element capable of moving relative to the base, and at least one actuator. Each actuator of the at least one actuator is configured such that when the actuator is driven the actuator moves into a hold position, wherein the actuator limits movement of the element. In a particular embodiment, the at least one actuator holds the element, or a portion of the element, at a particular position, angle, and/or attitude. In an embodiment, the at least one actuator is used to limit movement of the element when the device is turned off. The at least one actuator can be positioned to allow greater movement of the element when the device is turned on.
