| 20110070809 | APPARATUS AND METHOD FOR SPIRAL POLISHING WITH ELECTROMAGNETIC ABRASIVE - An apparatus and method for spiral polishing with electromagnetic abrasive has adopted the principle of electromagnetic and magnetic abrasive along with a lead screw to polish the inner or outer surface of a precise screw or a complicated part. The apparatus includes a clamp, a lead screw, a first electromagnet, and a second electromagnet assembled in an airtight space, wherein the airtight space is filled with magnetic abrasive which is driven by the rotation of the lead screw and the electromagnetic function to polish a processed part in a regular shape or in an irregular shape. | 03-24-2011 |
| 20100263182 | PIEZOELECTRIC TACTILE SENSOR - A piezoelectric tactile sensor comprises a piezoelectric membrane with a top surface, a transducer of elastic column with a bottom end surface to overlay over the top surface of the piezoelectric membrane and plural microelectrodes being sandwiched between the top surface of the piezoelectric membrane and the bottom end surface of the transducer in spread manner. When the transducer is subjected to an external stress, the piezoelectric membrane will generate uneven stress distribution to initiate dispersed microelectrodes output a corresponding induced voltage signal for being analyzed to figure out the direction and magnitude of the external stress. | 10-21-2010 |
| 20100207490 | PIEZOELECTRIC TACTILE SENSOR - A novel flexible tactile sensor for sensing the force direction was designed by introducing the concept of structural electrodes on a piezoelectric film. The structural electrodes comprised an elastomeric column and distributed microelectrodes between the column and piezoelectric film. As a periodic small force acts at the elastomeric column, the force is transferred to the piezoelectric film based on the column bending behavior, therefore the scale of force can be detected by the output voltages from the distributed electrodes due to the corresponding force state under the column. In addition, two opposite output signals from different sides of the column can differentiate the force direction as the column is bent by external force. The resulting signal for sensing force and its direction depends on the size of column. | 08-19-2010 |
| 20100136887 | Apparatus and method for polishing via driving abrasive grains mechanically and magnetically - Disclosed is a polishing apparatus including a shell, a magnetic controller, an axle, a pusher, a ring, posts, and a stirring element. The shell includes a roof, a floor and a wall between the roof and the floor. Abrasive solution is filled in the shell. The abrasive solution includes abrasive grains and magnetic material. The magnetic controller is located around the wall. The axle can be engaged with a rotary element of a machine. The pusher is connected to the axle and inserted through the roof. A ring is located between the pusher and the wall. Posts are located between the ring and the floor. The stirring element is located on the floor. | 06-03-2010 |
| 20100133163 | Magnetic filtering film - A magnetic filtering film is used to remove grains from liquid that goes through the magnetic filtering film. The magnetic filtering film includes a rubber film and micro-magnets. The rubber film is made of organic polymer. The rubber film is formed with apertures through which liquid can go. The micro-magnets are distributed in the rubber film for attracting ferromagnetic grains from the liquid. | 06-03-2010 |

| 20090289867 | WIDEBAND PRINTED DIPOLE ANTENNA FOR WIRELESS APPLICATIONS - In a broadband printed dipole antenna for wireless applications, metal plates of a radiation portion, a feed-in portion and a bandwidth modulation portion are formed on a substrate. Two radiation portions come with a specific shape and have an interval between the two radiation portions. The feed-in portion is composed of two separated long bars and coupled to one of the specific shaped radiation portions. The bandwidth modulation portion is disposed symmetrically adjacent to the feed-in portion, such that the impedance matching can be adjusted to form a broadband dipole antenna for WiMAX applications. | 11-26-2009 |
| 20090259193 | DISPOSABLE SYRINGE AFTER ONE TIME USAGE - A disposable syringe after one time usage includes an outer tube having an inner teeth set formed on the inner wall of the outer tube and an inner tube having an outer teeth set formed on the outer wall of the inner tube and a safety guide. The inner teeth set of the outer tube meshes with the outer teeth set of the inner tube. The single direction design of the teeth sets allows the outer tube to be pulled away from the inner tube, but not to be pushed back. The pulling force of the outer tube will pull the safety guide to form a damaged groove and the outer tube is adapted to enclose a needle so that the needle is not exposed outwardly, which prevents the needle from poking people accidentally. The syringe is unable to be reused. | 10-15-2009 |
| 20090068925 | SMART REMOTE CONTROL SYSTEM - A smart remote control system includes a remote controller and a remote control moving device. The remote controller includes a casing, a first direction finding unit, a signal transmission unit, and an operating unit that controls the advancing direction of the car. The remote control moving device includes a signal receiving unit to receive a control signal and a directional signal transmitted from the remote controller, a main control unit to receive the signal transmitted from the remote controller to control advancing speed and direction of the body, and a second direction finding unit detecting a relative direction between the remote controller and the moving device for the moving device to identify direction and move towards that direction. | 03-12-2009 |
| 20090066570 | DYNAMIC SPEED FINDING METHOD - A dynamic speed finding method to detect drive speed of a target, i.e., a speeding car, to serve as evidence in writing a traffic ticket is executed in the following steps: Step A: the position and speed of a speed finding object, i.e., a moving police car, are detected; Step B: the relative position and relative speed of the target are detected; Step C: the speed of the target is calculated; and Step D, the data of the speed of the target is stored. | 03-12-2009 |
