An information processing device including: a data processing unit that generates an encryption key of content; and a communication unit that transmits an encryption key generated by the data processing unit, wherein the data processing unit generates, as the encryption key, individual keys that are different for each new content recording processing on a recording medium in a content recording device, and transmits the individual keys through the communication unit.

A memory card reading method applied to an electronic device, includes: detecting a specification information of a memory card, wherein the specification information includes a transfer speed of the memory; and controlling according to the specification information a reader to host interface to operate in a first operating mode or a second operating mode for reading the memory card, wherein the first operating mode and the second operating mode correspond to different data transfer speeds.

The card reader includes a peak detector that detects a peak point of a reproduced signal according to a threshold. The peak detector applies, to a first peak value to be determined, a second peak value immediately before the first peak value, a third peak value, which is the second preceding peak value with respect to the first peak value, and a next peak value. When a difference between a first intermediate value, which is a value between the third peak value and the second peak value, and a second intermediate value, which is a value between the second peak value and the first peak value, is greater than or equal to a first difference value, the peak detector ignores a first threshold, and decides the first peak value after confirming that a digital value corresponding to the next peak value has exceeded a second threshold.

A peak detecting unit includes: a judging section, judging whether a current digital value produced by an AD converter has changed from a prior digital value; a holding section, being capable of holding the digital value output from the AD converter as an extreme value and its position information; and an updating section which, when the current digital value has changed from the prior digital value, updating the extreme value and its position information held in the holding section with the current digital value as a current extreme value and its position information, or when the current digital value matches the prior digital value, acquiring the intermediate position between the position of the current digital value and the position of the prior digital value as a current extreme value position, holding the matching digital value as a current extreme value, and updating the position information with the intermediate position information.

A card recognition system comprises an imaging device configured to capture a raw image of at least a portion of a card, and a processor operably coupled with the imaging device. The processor is configured to perform an image processing analysis of the raw image to identify measurements of at least one of a rank area around a rank of the card, and a suit area around a suit of the card, and automatically generate a calibration file based, at least in part, on the image processing analysis. A card handling device comprises a card infeed, a card output, and a card recognition system. A method for tuning a card handling device comprises capturing a plurality of images from a deck of cards, storing the images in memory, analyzing the plurality of images for card identification information, and generating a calibration file including parameters associated with the card identification information.

Technology is provided for a storage card adapter. The storage card adapter is used for housing storage cards (e.g., M.2 storage cards), and the storage card adapter can then be inserted into a drive bay. The storage card adapter includes an adapter frame and an adapter cover. The adapter frame includes a pair of guide posts having a ledge upon which one end of a storage card rests when the storage cards are installed in storage card connectors on a printed circuit board installed in the storage card adapter. The adapter cover includes a pair of clamping posts that are aligned to engage with the guide posts when the adapter cover is fully mated with the adapter frame. In this manner, the end of the storage card becomes clamped between the guide post and the clamping post to thereby secure the storage card within the storage card adapter.

A connector component for use in an electronic device for concurrently accepting multiple forms of data storage cards. The connector component comprises a housing shell, a housing shell support, a plurality of contacts, and a tray. The housing shell support includes a flexible bilateral surface with a first side that is coupled to the housing shell. In response to a force from an inserted data storage card, the housing shell support temporarily recoils, thereby decreasing an area between the housing shell and the housing shell support. The plurality of contacts is coupled to an exposed surface of the housing shell support. The plurality of contacts interconnects with a corresponding electrical contact on each inserted data storage card for electronically transferring electronic data. The tray has a capacity to hold at least three different forms of data storage cards for a concurrent insertion into a cavity of the connector component.
