Abstract:
The present invention provides a vehicle speed warning system and method for acquiring the images thereof. There is a speedometer image acquisition device, mounted correspondingly to the speedometer of the existing panel, and used to acquire the images of the speedometer. An image converter converts the images acquired by a speedometer image acquisition device into digital image data. A processor is used to receive digital image data and analyze the rotating angle of the pointer of speedometer. A memory stores the program of the vehicle speed warning system and digital image data of the speedometer. A display screen displays the speed value and/or the judgment result analyzed by the processor. The setting unit sets the warning threshold of the pointer angle of speedometer. A warning device, used to send a warning signal when the pointer angle of the speedometer exceeds the warning threshold set by the driver.
Abstract:
Embodiments of mechanisms for flattening a packaged structure are provided. The mechanisms involve a flattening apparatus and the utilization of protection layer(s) between the packaged structure and the surface(s) of the flattening apparatus. The protection layer(s) is made of a soft and non-sticking material to allow protecting exposed fragile elements of the packaged structure and easy separation after processing. The embodiments of flattening process involve flattening the warped packaged structure by pressure under elevated processing temperature. Processing under elevated temperature allows the package structure to be flattened within a reasonable processing time.
Abstract:
The present invention provides an apparatus and method for noise cancellation of voice communication. The apparatus includes a main body, loudspeaker, in-ear microphone, speaking microphone and adaptive control system. The method includes an external noise microphone arranged externally onto the main and used to acquire the noise outside of the ear drum, which is taken as the reference noise signal of adaptive control system. The in-ear anti-noise is estimated, so that the noise disturbance can be reduced when the receiving end receives remote voices. After noises and near-end voices are separated from near-end voices subjecting to noise disturbance, so that the accuracy of estimating anti-noise and the applicability of active noise cancellation is increased.

A method includes vacuum annealing on a substrate having at least one solder bump to reduce voids at an interface of the at least one solder bump. A die is mounted over the substrate.
Abstract:
The preset invention provides an Intrnet-based automatic security system and method. The security system includes a network server with a database, a network detection module and an automatic transmitting module, and a security device with a microcontroller, a virtual IP network module and wireless transmission module. The network detection module receives the information of security device and detects the networking state. The automatic transmitting module automatically transmits the alarm information from the network detection module to the client and security operator. The microcontroller links security components. The virtual IP network module employs a virtual IP address and links to a virtual IP router through a transmission interface. The security device also contains a polling module automatically linked to the network server for reading data.
Abstract:
A semiconductor package includes a workpiece with a conductive trace and a chip with a conductive pillar. The chip is attached to the workpiece and a solder joint region is formed between the conductive pillar and the conductive trace. The distance between the conductive pillar and the conductive trace is less than or equal to about 16 μm.
Abstract:
A method for immobilizing glycoprotein is disclosed. A surface is provided. Next, a boronic acid is contacted to the surface. The boronic acid is represented as Y—R—B—(OH)2 and includes a boronic acid group(B—(OH)2), a linker R, and a functional group Y, in which the boronic acid is bonded to the surface via the functional group Y. A glycoprotein is contacted to the boronic acid, wherein two spatially adjacent hydroxyl groups of a carbohydrate chain form a boronate ester with the boronic acid group of the boronic acid to immobilize the glycoprotein. The goal of site-specific and covalent protein immobilization without interfering the binding affinity of an antibody to antigen may be thus achieved with the reaction of boronic acid and the carbohydrate chain of Fc region.
