摘要:
A composite rotary-delivery worktable for use in an air container detection system, which is attached to a scanning passage of an air container diction system, said composite rotary-delivery worktable comprising a delivery assembly for carrying and delivering said air container; and a rotary assembly rotatable with a rotation axis, wherein said delivery assembly is attached to said rotary assembly such that said delivery assembly is rotatable with said rotary assembly when said rotary assembly rotates. The composite rotary-delivery worktable of this invention enables large-scale air containers to not only pass the scanning passage but also rotate freely within the scanning passage. This makes it possible to keep the scanning system fixed and stationary, thereby increasing the working reliability of the scanning system and reducing the design difficulty and complexity of the scanning system.

A device for inspecting contraband in an aviation cargo container includes: a turntable and a scanning system, the scanning system including a radiation source; a detector; a radiation source mounting structure; and a detector mounting structure for mounting the detector. Each of said radiation source mounting structure and said detector mounting structure includes at least one column assembly. The radiation source and the detector are mounted on the column assembly and allowed to synchronously ascend and descend along said column assembly. By combining different movement modes of the turntable and the scanning system, the device of the present invention can scan the object in various scanning modes. The device is stable in structure, convenient in installation, and occupies a small space. The device can inspect aviation containers over two meters long and/or over two meters wide and achieve a relatively high passing rate of the objects.

摘要:
Systems and methods for converting web-based applications that were written for an original form-factor that supports a single operating system (OS) interface to multiple other form-factors and OS interfaces. A conversion process may be performed on applications that include HTML code, web scripts, CSS styles and various image or multimedia resources. Each file in a source application package is parsed for elements that may be modified based on a source profile and target profile for different device form-factors. Individual elements are resized, converted, or wrapped with a plug-in or shim, thereby accommodating the differences between different devices with different interfaces, screen resolutions and operating environments.

An analog-to-digital converter is provided. The analog-to-digital converter includes a sampling-voltage providing circuit, a first comparison circuit, a second comparison circuit, and an encoder circuit. The sampling-voltage providing circuit provides a group of first comparison voltages and a group of second comparison voltages. The first comparison circuit performs a first comparison operation to an analog-signal input quantity according to the group of first comparison voltages to generate a first comparison digital quantity. The second comparison circuit selects second comparison voltages among the group of second comparison voltages according to the first comparison digital quantity and performs a second comparison operation to the analog-signal input quantity according to the selected second comparison voltages to generate a second comparison digital quantity. The encoder circuit encodes the first comparison digital quantity and the second comparison digital quantity and generates a digital quantity corresponding to the analog-signal input quantity.

A multiplying digital-to-analog converter (MDAC) is provided. The MDAC includes a sub DAC decoding circuit, a capacitor-switch circuit, and an operation amplifier circuit. The capacitor-switch circuit includes at least two sampling capacitor sets which are coupled in parallel. The number of sampling capacitors in one of the sampling capacitor sets is larger than or equal to two. Each sampling capacitor set is coupled to an analog-signal input quantity through a sampling switch and to a corresponding output terminal of the sub DAC decoding circuit through a decoding switch. The sub DAC decoding circuit decodes a digital quantity and outputs a corresponding analog signal at each output terminal, such that the corresponding analog signals are applied to the respective sampling capacitor sets through the decoding switches and summed by the respective sampling capacitor sets to obtain an analog-signal quantity corresponding to the digital quantity.
