Abstract: The present invention is an electronically controlled wide band vibrating tampon (ECWVT) apparatus to provide relief from feminine menstrual cramps and comprises a controllable vibration generator with selectable wide band vibration sources, an electromechanical transducer aka a vibration transmitter, and a disposable vibration transmitting tampon head (VTTH) to be inserted into the user's vaginal canal for customized and maximized relief from a user's menstrual cramps. Since only the VTTH is disposable and all other parts are reusable, the disposable cost is minimized.

Abstract: A simplified micro-magnetic based sensor and a system built with it for detecting or measuring acceleration, speed, position, placement, tilt, and vibration are disclosed for a reduced product size, simplified manufacturing process, and reduced product cost. Both simplified micro-magnetic sensor and simplified micro-magnetic sensor system include a primary micro inductor and a secondary micro inductor coupled with a micro magnetically permeable dynamic medium element that is small, simple and low cost to manufacture.
