Abstract: A method and a system for mental index prediction are provided. The method includes the following steps. A plurality of images of a subject person are obtained. A plurality of emotion tags of the subject person in the images are analyzed. A plurality of integrated emotion tags in a plurality of predetermined time periods are calculated according to the emotion tags respectively corresponding to the images. A plurality of preferred features are determined according to the integrated emotion tags. A mental index prediction model is established according to the preferred features to predict a mental index according to the emotional index prediction model.

Abstract: A light module of a headlamp includes a laser device, a liquid crystal panel, a light transmitting device, a wavelength converting device, and a projection device in sequence. The laser device has at least a laser emitter to project laser rays to the liquid crystal panel. The light transmitting device transmits the laser rays from the liquid crystal panel to the wavelength converting device. The wavelength converting device transforms the laser beam into white light and project out through the projection device. A heat sink is attached to the wavelength converting device to dissipate the heat.

Abstract: A light module of a headlamp includes several laser emitters, several collimators, a light circulating device, a liquid crystal panel, and a projection lens in sequence. The light circulating device includes a filter, a first polarizer, a first reflector, a wavelength transforming layer, a second reflector, and a second polarizer to convert laser rays of the laser emitters into white laser rays with a predetermined polarization for the liquid crystal panel, and finally to project out through the projection lens.

Abstract: A portable electronic device disposed in a car is provided. The portable electronic device includes a power switch, a vibration sensor and a controller. The power switch is used for providing a first power at a first state and providing a second power at a second state. The vibration sensor is used for outputting a vibration signal after sensing the vibration of the car. The vibration sensor is used for terminating the output of vibration signal when not sensing the vibration of the car. The controller is electrically connected to the vibration sensor and the power switch. When the controller receives the vibration signal, the controller controls the power switch to be at the first state and provide the first power. When the controller does not receive the vibration signal, the controller controls the power switch to be at the second state and provide the second power.

Abstract: An electronic apparatus, which has a first casing and a second casing, includes a first connecting unit, a second connecting unit, a covering unit and a linked unit. The first connecting unit is fixed on the first casing, and the second connecting unit is pivoted to the first connecting unit. The covering unit has a barrel portion, which covers the second connecting unit. When the covering unit rotates around the second connecting unit, the second connecting unit rotates relative to the barrel portion. A first end of the linked unit is fixed on the second casing, and a second end thereof is connected to the covering unit. When the covering unit rotates, the linked unit rotates relative to the covering unit. The electronic apparatus further includes a first touching unit connected to the covering unit for pulling the covering unit to a first location separating from the second connecting unit.

Abstract: An electronic device with sliding type heatsink including a printed circuit board, a heat dissipation module and at least a guide post is provided. Wherein, a heat-generating element is disposed on the printed circuit board, and the heat dissipation module is disposed on the heat-generating element. The heat dissipation module includes at least an elastic element which has an assembly hole. The assembly hole has a guide part and a first fixing part. Besides, the guide post protrudes from the printed circuit board and is located in the assembly hole. A side of the guide post has a groove. When the heat dissipation module moves a suited distance, the groove slides into the first fixing part from the guide part that makes the guide post fix with the first fixing part. Thus, the heat dissipation module can tightly fix on the heat-generating element.
