摘要： A positive differential signal trace and a negative differential signal trace are formed on different layers of a printed circuit board. A first ground trace is formed on the layer on which the positive differential signal trace is formed, and a second ground trace is formed on the layer on which the negative differential signal trace is formed. An insulation layer is positioned between the two layers and has a predetermined thickness. A differential mode impedance and a common mode impedance of differential signals are dependent on the predetermined thickness of the insulation layer, width and thickness of each differential signal trace, and a space between each differential signal trace and the corresponding ground trace formed on the same layer.

摘要： A tool connecting device includes a shaft having a non-circular socket opening for receiving a non-circular rotatable member of a tool member to allow the tool member to be selectively tilted relative to the shaft to different angular position. A protrusion is extended from the tool member for engaging with the shaft to anchor the rotatable member to the shaft and to prevent the tool member from being tilted relative to the shaft. A control ferrule may be slidably engaged onto the shaft to selectively retain the tool member in line with the shaft and to prevent the tool member from being tilted relative to the shaft, or to allow the tool member to be slanted and tilted relative to the shaft to different angular position.

摘要： A Bluetooth audio chip with multiple input/output sources is implemented on a monolithic integrated circuit. The Bluetooth audio chip includes a Bluetooth Baseband/RF module, an encode/decode module, a stereo ADC/DAC codec module, a USB module, a UART module, and a flash memory. Each one of the modules receives/transmits one kind of audio source, thus the Bluetooth audio chip has deeply embedded with multiple input/output sources. The Bluetooth audio chip is used in a diversity of applications to reduce the cost and time comparing to one purpose chip for just only one specific application.

摘要： A tool connecting device includes a tool mount having a non-circular socket opening for receiving a non-circular spatial engaging member of a tool shank to allow the tool shank to be selectively tilted relative to the tool mount to different angular position. An anchoring device may selectively anchor the tool shank and the tool mount together to retain the tool shank in line with the tool mount and to prevent the tool shank from being tilted relative to the tool mount to other angular positions. A magnetic member may attract the spatial engaging member of the tool shank to the tool mount. An actuating device may actuate a projection to detachably secure a tool member to the tool shank.
