Abstract: A light guide substrate, including a light coupling-in region with multiple first gratings, a light expansion region with multiple sub light expansion regions, and a light coupling-out region, is provided. Each sub light expansion region includes multiple second gratings. The sub light expansion regions include a first set of sub light expansion regions and a second set of sub light expansion regions. Each second grating in the first set of sub light expansion regions includes a first microstructure and a second microstructure. The light coupling-out region includes multiple third gratings. When an image light enters the light guide substrate from the light coupling-in region through the first gratings, the image light is first transmitted to the light expansion region in the light guide substrate, then transmitted to the light coupling-out region through the second gratings, and then emitted from the light coupling-out region through the third gratings.

Abstract: A remote client screen shots monitoring system for monitoring at least one client includes a preboot execute environment (PXE) module, a terminal multiplexing module, and a monitoring module. The PXE module controls the client to boot up. The client executes operations after booting us and generating screen shots in the process. The monitoring module obtains the screen shots from each client, converts each obtained screen shot to one file, and analyzes each converted file against certain predetermined words which may indicate a fault. The terminal multiplexing module places each generated screen shot together with those of other monitored clients in a display. The monitoring module can accordingly determine whether a fault exists in any one client. A remote client screen shots monitoring method is also provided.

Abstract: An image tracking device is applied to carry an electronic device and contains: an image capture unit, a processor, and a drive unit. The image capture unit is configured to capture images of objects and to produce data signals corresponding to the images. The processor is coupled to the image capture unit and is configured to process the data signals of the images from the image capture unit and to produce a driving signal. The drive unit is coupled to the processor and is configured to receive the driving signal from the processor so as to adjust an angle and a direction of the electronic device.

Abstract: A chip card ejecting mechanism includes a main body, a tray assembled in the main body and configured to receive a chip card, and a door. The door includes a rotating end rotatably mounted on the main body and a push pole protruding from the rotating end. A resisting portion is located on an end of the push pole away from the rotating end. When the door is opened and the rotating end is rotated relative to the main body, the resisting portion resists against the chip card and drives the chip card to move out from the main body.

Abstract: A portable electronic device (400) includes a housing (402) and a digital camera module (200). The housing has at least one arcuate housing surface section (4024) at one end thereof. The digital camera module is received in the housing proximate the one end thereof. The digital camera module includes at least one contact portion. Each contact portion has an arcuate contact surface (6400), and each such contact portion tightly engages a corresponding arcuate housing surface section. Owing to the tight engagement of such arcuate surfaces, the top surface of the digital camera module may fit closely against the housing so as to more fully use the space in the portable electronic device. This would help satisfy the miniaturization requirement of the portable electronic device.
