Abstract: A system for controlling distribution of protected content to portable mass storage media devices (10), the system comprising: a host application (200) for a host device (20) including: collection module (202) to collect predetermined identifiers of a portable mass storage media device (10) connected to the host device (20); a first key generation module (201) to generate an encryption key using a secret key and the collected identifiers; and an encryption module (203) to encrypt protected content using the encryption key when protected content is copied to the media device (10); and a client application (100) for the portable mass storage media device (10) including: a second key generation module (101) to generate the encryption key using a secret key and predetermined identifiers of the portable mass storage media device (10); and a decryption module (102) to decrypt data relating to encrypted protected content in sector buffer memory (12) of the media device (10) using the encryption key after each read o

Abstract: A portable digital device having at least two control devices for controlling at least two operating functions of the portable digital device; a digital display for displaying information; and a processor. The processor is for rotating the information from a right-handed orientation to a left-handed orientation and vice versa, and remapping the at least two control devices to reverse their operating functions to allow for use of the portable digital device in both the first orientation and the second orientation. Upon remapping skip forward and skip back operating functions are interchanged, increase volume and decrease volume operating functions are interchanged; and menu move to the left and right operating functions are interchanged.

Abstract: An imaging detector on a medical imager is provided with a proximity sensor for automatically maintaining a desired distance from the subject to be imaged. The proximity sensor is formed from three infrared beams at decreasing distances from the imaging detector. The imaging detector is moved toward the subject until the first two beams are interrupted. If the third beam is interrupted, the imaging detector is moved back from the subject until only the first beam is interrupted. Faults are detected by monitoring the order in which the beams are interrupted, whether the beams are interrupted when the imaging detector is fully retracted, and whether beams are present when no signal is applied to the beam emitters.
