Patent number: 7485993Abstract: A direct current (DC) brushless vibration motor includes an inductive coil as the stator, and a magnetic element, which has a plurality of coplanar magnetic poles, as the rotor. The inductive coil is a single annular coil formed by a singly-wound conductive wire. The winding area corresponds to two magnetic poles of the magnetic element of the like polarity at opposite sides. The magnetic element has a centrifugal slot to make the gravity center of the magnetic element eccentric from the axis. When current is input into the inductive coil to form a magnetic field, the magnetic element and the magnetic field generated by the inductive coil repulse each other to generate rotation. The eccentric gravity center of the magnetic element can generate the vibration desired.Type: GrantFiled: December 8, 2005Date of Patent: February 3, 2009Assignee: Risun Expanse Corp.Inventors: Chiang-Cheng Huang, Chun-Min Chang, Chien-Chung Sun

Publication number: 20080058915Abstract: This invention is related to a facial membrane mask and its device for cosmetic and health care applications. This invention is particularly related to transcutaneous electric acupoint stimulators and cosmetic facial membrane masks. The combination of these two devices results in synergistic effects. This invention uses a facial membrane mask that can absorb skin care solution. Electrodes are integrated with the membrane at the positions which correspond to facial acupoints. When the wet facial membrane mask covers the face, the electric pulses generated by the stimulator can stimulate the corresponding acupoints, nerve or muscle. The stimulation results in acupuncture or massage effects. Therefore, both the traditional facial membrane's skin care effects, such as moisturizing and whitening etc., and acupuncture/massage effects can be obtained concurrently. Being able to modulate facial meridians and improve subcutaneous blood circulation, this invention is useful for cosmetic and health care purposes.Type: ApplicationFiled: September 6, 2006Publication date: March 6, 2008Inventor: Chun-Min Chang
