    摘要: In one embodiment, a storage device with biometric access includes: a biometric scanner adapted to scan a biological feature of a user to provide a corresponding extracted biometric template; and a storage engine adapted to retrieve an encrypted biometric template from a storage medium and to retrieve a corresponding encrypted content key from the storage medium. The storage engine generates a first key and combines the first key with a media identifier from the storage medium to provide a content key. Using the content key, the storage engine decrypts the retrieved encrypted biometric template. If the extracted biometric template matches the retrieved biometric template, the storage engine grants a user access to content on the storage medium.

    摘要: The invention provides a single chip implementation of a digital receiver for multicarrier signals that are transmitted by orthogonal frequency division multiplexing. Improved channel estimation and correction circuitry are provided. The receiver has highly accurate sampling rate control and frequency control circuitry. BCH decoding of tps data carriers is achieved with minimal resources with an arrangement that includes a small Galois field multiplier. An improved FFT window synchronization circuit is coupled to the resampling circuit for locating the boundary of the guard interval transmitted with the active frame of the signal. A real-time pipelined FFT processor is operationally associated with the FFT window synchronization circuit and operates with reduced memory requirements.

    摘要: An apparatus and method for retrolasing plaque deposits in a coronary artery to remove same includes a tip assembly on the end of a flexible inner tube containing optical fibers that are slidable along a guide wire. The tip assembly includes a reflective surface rearwardly of a front face that directs laser energy supplied through the optical fibers in a rearward direction through a window portion to a focal point externally of the tip assembly. The deposit is removed as the tip assembly is moved in a rearward progression back through the deposit.
