Abstract:
An image lens, in the order from the object side to the image side thereof, includes a first lens including a first surface and a second surface, a second lens including a third surface and a fourth surface, a third lens including a fifth surface and a sixth surface, a fourth lens including a seventh surface and a eighth surface, a fifth lens including a ninth surface and a tenth surface, and an image plane. The image lens satisfies the following formulas: (1) D/TTL>0.94; (2) D/L>1.21; wherein D is the maximum image diameter of the image plane; TTL is a total length of the image lens, and L is a distance from an outmost edge of the tenth surface to an optical axis of the image lens along a direction perpendicular to the optical axis.
Abstract:
An optical touch device includes a touch panel, an infrared light pen, and an infrared camera module. The infrared light pen emits infrared light towards a surface of the touch panel. The touch panel includes a display panel and an infrared reflective element. The infrared reflective element is stacked on the display panel and faces the infrared camera module. The infrared reflective element reflects the infrared light to the camera module. The camera module captures images of the infrared light reflected by the infrared reflective element.
Abstract:
A lens adapter ring is provided for connecting a lens barrel to a lens holder whose thread specification is different from that of the lens barrel. The ring includes a first hollow cylinder. The cylinder includes a first inner surface and a first outer surface opposite to the first inner surface. The first outer surface includes a first outer thread portion adapted for the lens holder, and the first inner surface includes a first inner thread portion adapted for the lens barrel. The thread specification of the first outer thread portion is different from that of the inner thread portion. A lens module using the lens adapter ring is also provided.

A glass filter assembly includes a circular glass substrate, an annular first anti-fragility layer, and a second anti-fragility layer. The circular glass substrate includes a first surface and a second surface opposite to the first surface. The first anti-fragility layer is concentrically adhered to the first surface. The outer diameter of the first anti-fragility layer is greater than or equal to the diameter of the circular glass substrate while the inner diameter of the first anti-fragility layer is smaller than the diameter of the circular glass substrate. The second anti-fragility layer is concentrically adhered to the second surface. The outer diameter of the second anti-fragility layer is greater than the diameter of the circular glass substrate while the inner diameter of the second anti-fragility layer is smaller than the diameter of the circular glass substrate.
Abstract:
A mobile communication device includes a main body and a case. The case is rotatably received in the main body. The case is adapted to receive a battery and a subscriber identity module card. The battery is adapted to supply power to the mobile communication device. The subscriber identity module card is operable to store a service-subscriber key for identifying a subscriber of the mobile communication device. The case is operable to rotate relative to the main body, so as to expose the battery and the subscriber identity module card out of the main body.
Abstract:
An exemplary USB flash memory device includes a main body, a bending portion, a memory unit, and a connector. The main body includes a front wall, a back wall, and two side walls between the front and back walls. A transverse width of each of the front wall and the back wall is larger than a transverse width of each side wall. The bending portion is pivotably connected to the main body, a rotation axis of the bending portion is substantially perpendicular to the front wall and the back wall of the main body. The memory unit is received in the main body. The connector is electrically connected to the memory unit, the connector is secured to an end of the bending portion farthest away from the main body.
Abstract:
An aircraft exploration system includes an unmanned aircraft, a remote control, a communication processer and a data processing terminal. The an unmanned aircraft equipped with an MCU module, an image module, a first transceiver module and a GPS module, the above-mentioned modules are electronically connected to the MCU module. The unmanned aircraft is controlled by the remote control to fly. The data processing terminal is electronically connected to the communication processer, the GPS module senses the position signals of the unmanned aircraft and sends position signals to the data processing terminal, and the data processing terminal displays a map of an environment surrounding the unmanned aircraft promptly and in real time due to the positioning signals via internet.
Abstract:

The outer frame is received in the receiving space and rotatably suspended by the two first shafts. The inner frame is received within the outer frame rotatably suspended by the two second shafts, the first shafts are substantially perpendicular to the second shafts, the image capturing unit is received in the inner frame.
Abstract:
An exemplary lens module includes a substrate, a housing, a carrier, and a barrel. The housing is hollow, and disposed on the substrate. The carrier is received in the housing. The carrier defines a through hole. The barrel is received in the housing. The barrel includes a receiving body, a focusing portion, a connection portion, and a groove. The focusing portion is at a top end of the receiving body. The connection portion is at a bottom end of the receiving body. The groove spans from the top end of the receiving body to the connection body. The receiving body is received in the through hole of the carrier. The connection portion is mechanically connected to the carrier. A top end of the connection portion is exposed by the groove.
