Abstract: A system and method for labeling with a laser an optical disc having a plurality of markable locations. Signals indicative of a focus of the laser to the disc are measured, while rotating the disc at a constant angular velocity. Focus positions for designated ones of the locations to be marked on the disk are determined from the measured signals. The designated locations are marked with the laser while rotating the disc at a constant linear velocity and positioning the laser at the corresponding focus position. For at least some radial positions of the laser, an angular velocity corresponding to the constant linear velocity is less than the constant angular velocity.

Abstract: A computing device is described. The computing device can include a housing which includes a lid portion having a display; and a base portion including a keyboard, the lid portion and the base portion being configured to be locked in a first relative orientation such that the lid portion physically blocks a user from engaging the keyboard. The computing device can also include a data storage means positioned on the housing and configured to store a predetermined activation sequence; and, at least one user-engagable input mechanism which can be accessed by a user when the display and the keyboard are in the first orientation and upon which a user can enter a user-entered activation sequence, and wherein if the user entered activation sequence equals the predetermined activation sequence the base portion and the lid portion can be unlocked from the first orientation.

Abstract: A computing device is described. The computing device can include a base portion and a lid portion connected to the base portion. The lid portion is configured to be deployed from a closed position to an open position. The computing device can also include a locking mechanism for locking the lid portion in the closed position. The computing device can further include multiple user-engagable input mechanisms, at least some of the multiple input mechanisms being accessible when the lid portion is in the closed position and which can be manipulated by a user to unlock the locking mechanism.
