20110293130 | EARPHONE - An earphone comprises a trumpet unit, a hollow shield, and a guide sound tube: the shield is hollow to receive the trumpet, has a sound chamber and an opening, and the opening inclines an acute angle from the trumpet unit; the guide sound tube is disposed at the opening with an end communicating with the sound chamber and another end extending to the opening. The earphone is capable of presenting the high and low pitches completely and providing a better sound quality by way of the acute angle between the opening and the trumpet unit. | 12-01-2011 |
20120275632 | EARPHONE - An improved earphone comprises a shield member consisting of a front shield part and a rear shield part, and a speaker unit. The front shield part is provided with a cover section with an egg-shaped profile, and has a front side which has a little concave outward shape. The rear shield part extends and converges from the front shield part gradually to form a circular cone section, and further extends to form a connecting tube section. The speaker unit is disposed in the receiving room of the front shield part, and has a center deviates from the center of the front shield. In this way, the earphone can be plugged to the ear tightly, and the speaker unit is capable of aligning with the external auditory canal precisely to concentrate the sound and lessen volume and base of the sound being lost for enhancing the sound quality. | 11-01-2012 |

20150219176 | ACTIVE VIBRATION ABSORBER - An active vibration absorber is attachable to a structure incorporating a positioning system which serves to vibrate the structure during its operation. The active vibration absorber comprises a mounting portion for attachment to the structure, an inertial mass that is resiliently coupled to the mounting portion and a force actuator which is operative to controllably move the inertial mass relative to the mounting portion. The force actuator is configured to move the inertial mass relative to the mounting body according to a motion profile during a motion cycle of the positioning system in order to attenuate vibrations in the structure. The motion profile is determined from a motion command which is operative to drive the positioning system during the motion cycle. | 08-06-2015 |

20150193978 | IMAGE PROJECTOR - An image projector for augmenting the appearance of a physical object is disclosed, also known as an augmented reality projector. The augmented reality projector comprises an optical arrangement to provide the possibility of precise matching of a projected image of the physical object back onto the object itself, instead of using digital image processing to do so. Digital image processing may be used to enhance features of the image and is not required for resizing or orienting the image to the object. This reduces the need for computational power to process the image and spares processing resources to refresh the image in real time. Accordingly, the processed image can be refreshed to change the appearance of a moving object. Furthermore, the precise matching provides the possibility of using projected images a graphical use interface, as movements of a user's fingers on the interface can be determined accurately. | 07-09-2015 |
