Abstract:
A lens module includes a lens barrel receiving a first lens, an annular light-shielding plate, and a second lens. The first lens includes a first imaging portion and a first non-imaging portion surrounding the first imaging portion. The first non-imaging portion includes a first mounting surface and a second mounting surface opposite to the first mounting surface. The second lens includes a second imaging portion and a second non-imaging portion surrounding the second imaging portion. The second non-imaging portion includes a third mounting surface. The first mounting surface, the second mounting surface, and the third mounting surface are perpendicular to an optical axis of the lens module. The light-shielding plate is mounted between the second mounting surface and the third mounting surface and totally covers the first non-imaging portion in a projection plane perpendicular to the optical axis.
Abstract:
A method for inspecting substrate internal defects is disclosed. The method provides at least one light source disposed on a lateral side of a substrate and configured to emit a light beam to the lateral side for correspondingly penetrating the substrate. The method also provides an image capturing module for retrieving an image of the upper surface, wherein an incident angle of the light beam to the respective lateral side is limited within a first predetermined angle to allow the light beam to have a total reflection in the substrate. Thus, the light beam is blocked by internal defects when transmitting within the substrate to generate bright spots to be detected by the image capturing module for locating the defect position. The method provides a better image definition of internal defects images. The present invention further provides an apparatus based on the method for inspecting substrate internal defects.
Abstract:
A solder apparatus includes a platform, an operating mechanism, a solder member, a heater, and a control box module. The control box module includes a temperature controller and a temperature sensor. The temperature controller defines a predetermined temperature. The temperature sensor is capable of measuring the temperature of the solder member. The temperature controller has the heater heat the solder member when the measured temperature of the solder member is lower than or equal to the predetermined temperature, and has the heater stop heating the solder member, when the measured temperature of the solder member is higher than the predetermined temperature.
Abstract:
The invention provides a method for preventing a mobile communication device from leaking secret and a system thereof. In the method, by adopting a mobile communication device side and PC side structure, a controlling module installation package is transferred from a PC side to the mobile communication device; a controlling module runs automatically and obtains root privilege of the operating system of the mobile communication device; the controlling module forbids functions of silently dialing, silently answering, photo taking, video recording, voice recording, Bluetooth and infrared connection. The advantages of the present invention are that the present invention is suitable for on-site operation and possibility of leaking secret by any mobile communication device is eliminated by a PC terminal.

A mouse charging device is applying to an electronic device which comprises a power supply and a first connecting port. The mouse charging device comprises a mouse and a receiver. A charging module of the mouse is disposed in a shell of the mouse, and a first conductive piece of the mouse is disposed on the shell. The first conductive piece is electrically connected to the charging module. The receiver comprises a second connecting port and a second conductive piece. The second connecting port is electrically plugged in the first connecting port and electrically connected to the power supply. The second conductive piece is selectively coupled to the first conductive piece of the mouse. As the second conductive piece and the first conductive piece are coupled together, the power supply of the electronic device is available to charge the charging module of the mouse.
Abstract:
A node apparatus and an adjusting method of a quantity of nodes for a sensor network and a tangible machine-readable medium thereof are provided. The sensor network comprises a plurality of groups, wherein each group has a plurality of nodes. For each group, one of the nodes is set to be a gate node, and each node within the group transmits at least one data of itself to the corresponded gate node. Each gate node calculates a data aggregation time based on a data length per unit time of received data and a predetermined packet length, so that each gate node is able to adjust the quantity of nodes within the group thereof accordingly.
Abstract:
Self-triggered Multi-finger SCRs used in ESD protection circuitry capable of turning on all SCR fingers of the multi-finger SCRs include a first source, a second source, N SCR units, (N−1) diodes, and N resistors. Each of the N SCR units includes a first node, a second node coupled to the second source, and a trigger node. An nth diode of the (N−1) diodes is coupled between a first node of an nth SCR unit and a trigger node of an (n+1)th SCR unit. An nth resistor is coupled between the first node of the nth SCR unit and the first source, wherein n and N are integers. The (N−1) diodes can be replaced by directly coupled the first node of the nth SCR unit to the trigger node of the (n+1)th SCR unit when a trigger pulse is applied at the trigger node of a first SCR unit.
Abstract:
A lens module includes a lens barrel, a first lens, a second lens, and a spacer. The lens barrel includes an object-side end and an image-side end opposite to the object-side end. The first lens is received in the lens barrel, and adjacent to the object-side end. The second lens is received in the lens barrel, and adjacent to the image-side end in relative to the first lens. The spacer is an annular plate, and includes an object-side surface, an image-side surface opposite to the object-side surface, and an inner sidewall. The spacer is positioned between the first lens and the second lens. The object-side surface faces the first lens, and the image-side surface faces the second lens. The intersection of the object-side surface and the inner sidewall forms a chamfer.
Abstract:
Enhanced paging mechanisms are proposed for Machine Type Communication (MTC) devices in 3GPP networks. First, adaptive paging is proposed to adaptively allocate extra paging occasions for MTC devices with no extra procedure or power consumption on normal UEs. Second, group paging is proposed to simultaneously page a plurality of MTC devices with one paging. Group paging is controlled in different levels for optimized signaling and easier management. In one embodiment, group broadcasting and group release are used. Third, paging with response policy is proposed to pre-define or dynamically configure paging response policies for MTC devices.
