Techniques for managing data in a non-volatile memory system (e.g., Flash Memory) are disclosed. A controller can use information relating to a host's filing system, which is stored by the host on non-volatile memory, to determine if one or more clusters (or sectors with clusters) are currently allocated. The controller can use the information relating to the host's filing system to ensure that one or more clusters (or one or more sectors within a cluster) are not copied from one location to another location in the memory during a garbage collection cycle. As a result, some unnecessary operations (e.g., copying data) which are conventionally performed can be avoided and system performance can be enhanced.

In the shop POS register terminal, the settlement request generating unit generates settlement request information including an amount of settlement upon receipt of an operational input of IC card settlement; and the request barcode generating unit generates a request barcode from the settlement request information, and causes the POS register terminal to display on the screen or to print for output. In the cell phone, the request barcode restoring unit images the request barcode by the camera; the IC card settlement unit subtracts the amount of settlement of the restored settlement request information from the value charged to the IC chip of the cell phone; the settlement response generating unit generates settlement response information including a balance after settlement of the IC chip; and the response barcode generating unit generates a response barcode from the settlement response information, and causes the cell phone to display the same on the screen. In the POS register terminal, the response barcode restoring unit reads out the response barcode to restore the settlement response information; the IC card settlement ending unit confirms the end of the IC card settlement from the restored settlement response information, and causes the POS register terminal to print the receipt for output.

An event processing system that can perform processing corresponding to event messages certainly, and improve efficiency of processing event messages.

To that end, the event processing system of the present invention holds event messages, which are received owing to state transitions of an IT service system, in an event message holding unit in order of issue. Among the event messages held in the event message holding unit, the event processing system searches for an event message for which a state of the IT service system after issue of the event message in question coincides with a state of the IT service system before issue of the oldest event message in the event message holding unit. When the event processing system can retrieve the event message in question, the event processing system deletes event messages ranging from the oldest event message to the retrieved event message from the event message holding unit.

A ventilation hole is formed in a rear portion of the luggage compartment. An inlet is opened toward the outside of the vehicle. An exhaust fan that discharges the cooling air at the temperature increased through heat transfer with the battery in the battery pack is provided to the front of the ventilation hole.

There is provided a content use management method capable of preventing unauthorized distribution of a content and improving user-friendliness. In this method, the same group key is stored in a secure device (400) and a playback terminal (500). Moreover, a license issuing application is received from a license distribution server (200) and stored in the secure device (400). After this, a license encrypted by the group key is sent to the playback terminal (500) and the license encrypted by the group key is stored in the playback terminal (500). Upon playback of the encrypted content, the playback terminal (500) decrypts the license by using the group key and acquires the content decryption key, thereby decrypting the encrypted content. Even when the encrypted license flows into the network, it cannot be decrypted by a playback terminal not having the same group key and the copyright is protected. Moreover, the playback terminal (500) which already holds the group key and the license encrypted by the group key does not need the secure device when reproducing the encrypted content.

An automotive vehicle defogging system prevents dissipation of energy required to defog the automotive vehicle wind shield. A surface temperature sensor mounted on the wind shield detects the glass surface temperature. A humidity sensor spaced from the wind shield glass by a predetermined distance detects the humidity around the wind shield. A peripheral temperature sensor mounted inside from the wind shield glass detects peripheral temperature around the glass. Dew point temperature is obtained in response to the detected humidity H and a temperature value based on the temperatures detected by the surface and peripheral temperature sensors. The presence of fog is detected by comparing the dew point temperature with the surface temperature Ts.

The invention relates to a method of producing and checking a double-resonator honeycomb acoustic panel. The aforementioned panel is characterised in that, following the assembly of the two honeycombs (30, 50) and the partition (40) and prior to the assembly of at least one of the two liners (20, 60), the perforation rate of said partition (42) is checked by scanning same with digital camera (84). The successive images (92) thus obtained are transmitted to a computer (94) which determines the perforation rate T of the partition (40) by applying formula T=N1/N, wherein N1 is the number of pixels (100) that correspond to the holes (42b) and N is the number of pixels in the image (92).
