Abstract:
A CPU casing structure includes a casing body having a rear wall on which a side wall is mounted to define an open front side for receiving a nonpackaged a CPU therein. A heat dissipator having a base positionable over and in physical contact engagement with the CPU to provide heat transfer therebetween is releasably secured to the front opening of the casing body by means of at least one clip so as to substantially cover the front opening and thus house the circuit board and the CPU therein. The casing body has at least one clip anchoring members formed on the top edge thereof. The clip have a central section selectively postionable on the base of the heat dissipator and a fixed, but preferably resilient, end extension extending through holes formed on the casing body, the circuit board and the heat dissipator. The end extension has a bending on the free end thereof and the bending is formed as an acute angle to be received within a sloped cavity having an inclination of substantially the same angle formed on the casing body. The clips also have a movable extension defined by a hinged tab having a slot engageable with the respective anchoring member to secure the clips and thus fix the heat dissipator to the casing body together.
Abstract:
A warning method and system for detecting lane-changing condition of rear-approaching vehicles are disclosed, in which the method comprises the steps of: detecting rear-view images of an ego-vehicle so as to be used for defining three regions of interest (ROI) corresponding respectively to a lane to the left of the ego-vehicle, a lane to the right of the ego-vehicle, and a lane where the ego-vehicle is travelling thereon; detecting whether there is any direction light that is flashing to be used as basis for determining whether there is any vehicle approaching from the rear that is expected to be a potential threat to the ego-vehicle; and if so, issuing an alarm signal to the driver of the ego-vehicle for reminding the same to aware the distance between the ego-vehicle and the rear-approaching vehicle. Thereby, the driver's road environment awareness is enhanced and consequently the safety of driving can be improved.
Abstract:
A method and an apparatus for single-image-based rain streak removal are introduced herein. In this method and apparatus, an original image is decomposed into a high frequency part and a low frequency part, and the high frequency image is then decomposed into a rain part and a non-rain part. The non-rain high frequency image and the original low frequency image are used to produce a non-rain image.
Abstract:
An illumination device for plants includes a lighting unit mounted on a lamp seat and including a cold cathode fluorescent lamp and a light emitting diode (LED) unit. A driving unit is mounted to the lamp seat, is coupled to the cold cathode fluorescent lamp and the LED unit, and is operable so as to drive the cold cathode fluorescent lamp and the LED unit such that the cold cathode fluorescent lamp and the LED emit respectively color lights having respective wavelengths. A dimming unit is coupled to the driving unit, and is operable so as to output a dimming output to the driving unit. The driving unit drives the cold cathode fluorescent lamp and the LED unit based on the dimming output from the dimming unit so that the color light emitted by each of the cold cathode fluorescent lamp and the LED unit has a respective light intensity.
Abstract:
The present invention relates to a control system for an electrostatically-driven microelectromechanical device, which uses multiple electrodes to control the microelectromechanical device, i.e. the lower driven electrode of a capacitor with known two parallel driven electrodes is cut into a number of small electrodes. By selecting an electrode pattern for a desired electrostatic force, it is capable of altering the non-linearity of the device based on various applications and achieving a characteristic such as a linear driven, digital driven, or ultimately optimal driven manners, which is able to reach high operation accuracy for the existing circuit that only possesses a limited accuracy.
Abstract:
A lighting device includes a light fixture, a semiconductor light source and a gas-discharge light source mounted in the light fixture, and a controller disposed in the light fixture and connected electrically to the semiconductor light source and the gas-discharge light source. The controller is operable to control activation and deactivation of the semiconductor light source and the gas-discharge light source. Heat generated during operation of the semiconductor light source may increase the ambient temperature in the light fixture such that optimum performance of the gas-discharge light source may be ensured.
Abstract:
A lamp device includes: a lamp unit mounted in a lamp housing; and a circuit unit disposed in the lamp housing for activating the lamp unit to emit light when receiving an external voltage through opposite connecting ports mounted on the lamp housing. The lamp unit includes two cold cathode fluorescent lamps (CCFLs) connected in series. Each CCFL includes a lamp tube that has a first tube segment connected to a first electrode portion and extending in a first direction, a second tube segment connected to a second electrode portion and extending in a second direction transverse to the first direction, and a curved third tube segment interconnecting the first and second tube segments. For each CCFL, a ratio of a length of the lamp tube in the second direction to a length of the same in the first direction is less than 25%.
Abstract:
A heat dissipation device includes a retention module, a heat sink, a locking plate and a clip rotatably connecting with the retention module. The retention module includes an opening in a center thereof. The heat sink includes a heat conducting body and plurality of fins radially extending from the heat conducting body. The heat conducting body has a bottom portion received in the opening of the retention module. The locking plate engages with the bottom portion of the heat conducting body of the heat sink. The locking plate has a first portion abutting a bottom of the retention module, and a second portion opposite to the first portion. The second portion is pressed by a pressing portion of the clip when the heat dissipation device is at a locked position.
