An electronic carrier board is provided, including a carrier, at least two paired bond pads formed on the carrier, and a protective layer covering the carrier. The protective layer is formed with openings corresponding in position to the two bond pads. The openings are aligned in the same direction and expose at least a first sidewall and a second sidewall of each of the two bond pads. The first sidewall is perpendicular to an alignment direction of the bond pads and the second sidewall is parallel to the alignment direction of the bond pads. A distance between the first sidewall of at least one of the bond pads and a corresponding side of a corresponding one of the openings is at least about 50 μm greater than a distance between the second sidewall of the at least one bond pad and a corresponding side of the corresponding opening.
Abstract:
A method and system for generating test pulses to test electronic elements are disclosed. After determining a transmission clock, which is smaller than a test clock, and a serial of predetermined pulses, the serial of data bits corresponding to the serial of predetermined pulses can be generated. Then the serial of data bits can be transformed into a serial data stream for transmission. By transmitting the serial data stream according to the transmission clock, the serial of predetermined pulses corresponding to the test clock can be generated.
Abstract:
A self-contained/interruption-free earth's surface positioning method and system, carried by a user on the earth's surface, includes an inertial measurement unit, a north finder, a velocity producer, an altitude measurement device, a GPS (Global Positioning System) receiver, a data link, a navigation processor, a wireless communication device, and a display device and map database. Output signals of the inertial measurement unit, the velocity producer, altitude measurement device, the GPS receiver, the data link, and the north finder are processed to obtain highly accurate position measurements of the user. The user's position information can be exchanged with other users through the wireless communication device, and the location and surrounding information can be displayed on the display device by accessing a map database with the user position information.
Abstract:
A light source module of a projector includes a first light source, a second light source, a light assembly and a color wheel. The first light source and the second light source are used for generating first light and second light. The light assembly includes a first light pipe, a second light pipe and a third light pipe. The first light pipe and the second light pipe are used for changing directions of the first light and the second light. The third light pipe is disposed near the first light pipe and the second light pipe, for integrating the first light and the second light and outputting third light. The color wheel has a center and includes color filtering areas symmetric to the center. The first light and the second light have the same color by passing through the symmetric color filtering areas.
Abstract:
The present invention provides a method and system for an innovative design of the automatic stabilization and pointing control of a device based on the MEMS technology, which is small enough and has acceptable accuracy to be integrated into many application systems, such as, laser pointing systems, telescopic systems, imaging systems, and optical communication systems.

Abstract:
Apparatus and method of automatically cleaning a pick-up head is disclosed. After picking up and placing down the dies many times, the pick-up head is placed on a glue-tape to attract contaminants, thereby automatically cleaning the pick-up head and preventing the dies from being damaged.
Abstract:
A subscriber identity module (SIM) card connector that can be embedded within a mobile communication device is provided. The SIM card connector comprises a body having an accommodating space for disposing a SIM card and multiple connected-through receptacles for receiving conducting terminals. Through the conducting terminals, an electrical signaling contact with the SIM card can be made. The connector further includes a guide arm having a first salient block and a second salient block. The first salient block and the second salient block are disposed on the respective sides of the guide arm and a cover is connected to the body for covering the accommodating space. Furthermore, the cover may connect with the guide arm through a pivot. The cover further comprises a groove. When the second salient block is moved, the first salient block shifts inside the groove and push the SIM card out from the accommodating space.
