Abstract: A data transmission apparatus includes: a first port and a second port which are selected by a first control signal; a first signal path and a second signal path which are selected by a second control signal. When a memory card satisfies a first condition, the first control signal selects the first port and the second control signal selects the first signal path, the data transmission apparatus connects the host device and the memory card via the first port and the first signal path and works in a first transmission mode. When the memory card satisfies a second condition, the first control signal selects the second port and the second control signal selects the second signal path, the data transmission apparatus connects the host device and the memory card via the second port and the second signal path and works in a second transmission mode.

Abstract: A data platform including an error handling framework for loading of input data. The data platform generates input data columns based on an input file and generates result data columns based on the input data columns and evaluating expressions. The data platform detects projection errors during the generating of the result data columns and stores result error indicators in error indicator arrays of the result data columns based on the projection errors. The data platform generates filtered result data columns based on the result data columns and the result error indicator arrays of the result data columns and stores the filtered result data columns in a database of the data platform.

Abstract: A multi-section expandable device includes an expansion module, a first push member and a second push member disposed at front and rear ends of the expansion module, and a bolt screwedly connected to the first and second push members. When the bolt is tightened, the first push member and the second push member are pushed to approach each other so as to push the expansion module to generate a first-stage expansion and a second-stage expansion. The first-stage expansion enables the expansion module to expand laterally so as to adjust its width. The second-stage expansion is performed after the expansion module is laterally expanded to have a maximum width, so that the expansion module is longitudinally expanded to adjust its height. The multi-section expandable device not only has better support effect, but also avoids the wear of the contact surfaces of the vertebrae.

Abstract: A notebook computer can receive a satellite navigation system (SNS) signal from satellites and realize a navigation function. The notebook computer includes a navigation device, a peripheral component interconnect (PCI) bus and a CPU. The navigation device is used for receiving the SNS signal and generating an intermediate frequency (IF) signal by down-converting a frequency of the SNS signal. The PCI bus coupled to the navigation device is used for transmitting the IF signal. The CPU is coupled to the navigation device via the PCI bus and is for reading and processing the IF signal to output a position, velocity and time (PVT) information signal for the notebook computer to realize the navigation function.
