Abstract:
An optical actuator includes a base, a carrier, a reflecting optical element, a connecting structure and an actuating component. The reflecting optical element is disposed at a first side of the carrier. The connecting structure has a first connecting portion located at the central region thereof and two second connecting portions located at two opposite sides thereof. The connecting portions connect the base to the second side of the carrier. The actuating component is disposed on the base and drives the carrier rotating along an axial line. The axial line is substantially perpendicular to the connecting structure. A projection system including the optical actuator is also disclosed.
Abstract:
This present invention provides a navigation system and a portable head up display thereof. The navigation system comprises a navigation apparatus and a portable head up display. The navigation apparatus is for generating a command with navigation message. The portable head up display is for receiving and processing the command with navigation message in wired or wireless manner, and then displaying the graphic data corresponding to the navigation message. Furthermore, the portable head up display is able to broadcast an acoustic data corresponding to the navigation message. Hereby, a user owning the personal navigation device (PND) can place this portable head up display in the vehicle, and the effectiveness of the navigation message displayed on the windshield can be achieved.
Abstract:
The light tunnel structure includes a plurality of reflectors joined together to form a light tunnel for allowing a light beam to pass and reflect therethrough. The plurality of reflectors have edges at an end of the light tunnel structure, wherein not all of the edges at the end are positioned at the same plane.
Abstract:
A light tunnel device. The light tunnel device includes a plurality of reflectors and at least one sleeve. The sleeve completely or partially covers the reflectors. The reflectors are piled together to form a hollow tunnel, allowing a light to pass therethrough. The profile of the reflectors is trapezoid, rectangular or polygonal.
Abstract:
A keyswitch controller includes a housing, a circuit board, a keyswitch module, and a force feedback module. The housing includes a keyswitch hole. The circuit board is disposed in the housing and includes a switch. The keyswitch module disposed on the circuit board and passing out of the keyswitch hole is for turning on the switch by being pressed so as to generate a pressing signal. The force feedback module is coupled to the keyswitch module for vibrating according to the pressing signal.
Abstract:
The present invention relates to a computer system capable of adjusting the operating frequency dynamically and comprises at least a processor voltage-adjusting unit, a clock-generating circuit, at least a load-detecting unit, and a control unit. The processor voltage-adjusting unit and the clock-generating circuit produce a processor operating voltage and a clock signal, respectively, and transmit them to the processor. The load-detecting unit detects the processor for producing a detecting signal related to the load of the processor. The control unit produces a clock-adjusting signal and a processor voltage-adjusting signal according to the detecting signal and controls the processor voltage-adjusting unit and the clock-generating circuit, respectively. Thereby, the control unit can adjust the operating voltage of the processor as well as the frequency of the clock signal and hence adjusting the operating frequency of the processor. According, the purpose of adjusting the performance of the computer system dynamically can be achieved.
Abstract:
A motor having a magnetic fluid bearing structure, which includes at least one bearing, at least one magnetic element and a magnetic fluid. The bearing is telescoped onto a shaft, and the magnetic element is coupled to the bearing. The magnetic fluid is kept between the bearing and the shaft. According to a magnetic effect between the magnetic fluid and the magnetic element, it is possible to prevent a lubricant of the bearing from leaking, and a hydraulic pressure of the magnetic fluid provides additional axial and radial supports to make the shaft rotate steadily relative to the bearing.
Abstract:
A color wheel includes a color filter set, a carrier, and a cap. The color filter set has a through hole, a first side and a second side which is oppositely disposed. The carrier is disposed at the first side of the color filter set and has a first engaging portion. The cap is disposed at the second side of the color filter set and has a second engaging portion for coupling with the first engaging portion, wherein either the first engaging portion or the second engaging portion passes through the through hole.
Abstract:
An attachable frame for flat display panels includes a flat display panel, a main structure, a bracing structure, a front frame and a rear frame. The main structure and the bracing structure provide bracing and steady support for the entire body. The front frame and the rear frame provide a desired appealing for the entire body. The main structure, bracing structure, front frame and rear frame are separable elements and are designed according to the dimension of the flat display panel. They may be assembled to form the exterior of the flat display panel, and become attachable to the flat display panel.
