摘要:
A vehicle risk analysis system, includes: a historical database, storing the sensing data and accident records acquired from multiple sampled vehicles into big data; a learning unit, connected to the historical database for analyzing the relationship between accident records and driving scenarios, to generate a risk classification model, which can further predict the risk of accidents for a vehicle in-use; and a risk profiling unit, receiving the risk classification model from the learning unit and acquiring the sensing data from the vehicle in-use, to generate a risk profile for the vehicle in-use under different driving modes. The risk profile reports the expected risks of accidents under different driving modes by using the occurrence rates for different driving scenarios and the expected losses of money caused by accidents, wherein each of the driving scenarios can be determined by a combination of the sensing data. The system can suggest an optimal driving mode for the vehicle in-use by using the risk profile, which can be further used to price the insurance premiums under different driving modes.

Techniques are presented for sending an application instruction from a hosting digital appliance to a portable medium, where the instruction is structured as one or more units whose size is a first size, or number of bytes. After flushing the contents of a cache, the instruction is written to the cache, where the cache is structured as logical blocks having a size that is a second size that is larger (in terms of number of bytes) than the first size. In writing the instruction (having a command part and, possibly, a data part), the start of the instruction is aligned with one of the logical block boundaries in the cache and the instruction is padded out with dummy data so that it fills an integral number of the cache blocks. When a response from a portable device to an instruction is received at a hosting digital appliance, the cache is similarly flushed prior to receiving the response. The response is then stored to align with a logical block boundary of the cache.

A file system and method of file access are disclosed. In a particular embodiment, a method is performed at a host device coupled to a non-volatile memory, where the host device includes a memory having a first file data structure. A first directory entry in a file directory of a file system is located where the first directory entry corresponds to a first file stored in the non-volatile memory. First data associated with the first directory entry, including first location data indicating a location of the first file in the non-volatile memory, is retrieved and stored in the first file data structure. A request to open the first file is received. In response, the first location data of the first file is retrieved from the first file data structure and data of the first file from the non-volatile memory is read. First metadata associated with the first file is extracted from the data read from the non-volatile memory.

A transistor structure disposed on a substrate includes a gate electrode, a gate insulating layer overlapping the gate electrode, a channel layer overlapping the gate electrode, and a plurality of first electrodes and a plurality of second electrodes overlapping the gate electrode. The gate insulating layer is disposed between the channel layer and the gate electrode. Besides, the gate insulating layer is located among the first electrodes, the second electrodes, and the gate electrode. The first electrodes and the second electrodes are alternately arranged along a first direction. Each of the first electrodes has a first width along the first direction. Each of the second electrodes has a second width along the first direction. A ratio of the first width to the second width ranges from 2 to 20. A driving circuit structure having the transistor structure is also provided.

A method of accessing content includes installing a file system filter for a secure removable memory device on a host device. A challenge is sent from the file system filter to a software entity on the host device, and a software entity response is received at the file system filter in response to the challenge. A file system filter response is calculated at the file system filter using the challenge, and access to first content on the secure removable memory device is provided if the software entity response matches the file system filter response.

Technology for replacing a first storage unit operatively coupled to a device is provided. Content of the first storage unit is sent to a new storage unit that serves as the replacement of the first storage unit. In one embodiment, the content is first sent to a trusted third-party server and then transferred from the server to the new storage unit. A portion of the content on the new storage unit is adjusted in one embodiment to maintain content security features that were implemented in the first storage unit. The upgrading can be performed under the control of a software entity that is installed on the device. In various embodiments, the first storage unit may be bound to a third storage unit prior to the upgrade process. In such cases, the process can include measures to bind the new storage unit to the third storage unit.

In order to write data to a storage system accessible with a first and second file system, a manager receives a data write request associated with a file. The manager determines if a function supported by the second file system is needed to complete the write request. If so, the file is opened and extended with the first file system. The file is then opened and written to by the second file system. The file is truncated by the first file system, and closed by both file systems. If the second file system function is not needed, the file is opened, written, and closed by the first file system. In order to read data from a storage system using a function supported by the second file system, the second file system's cached storage system index is updated, and then the file is opened, read, and closed by the second file system.
