Title: Security system and method for computer operating systems
Inventor: KABZINSKI RICHARD
IPC: G06F12/14
Filed: 2004-03-29
Abstract: A security system for a computer operating system comprising a processor (37) that is independent of the host CPU (13) for controlling access between the host CPU (13) and a security partition formed in the storage device (21) for storing the operating system. A program memory (41) that is independent of the computer memory and the storage device (21) unalterably stores and provides computer programs for operating the processor (37) in a manner so as to control access to the security partition in the storage device (21). All data access by the host CPU (13) to the data storage device (21) is blocked before initialisation of the security system and is intercepted immediately after the initialisation under the control of the processor (37). The processor (37) effects independent control of the host CPU (13) and configuration of the computer (11) to prevent unauthorised access to the security partition on the storage device (21) during the interception phase. All users of the computer (11) are authenticated with a prescribed profile of access to the operating system files in the security partition on the storage device (21) and data access to the storage device remains blocked until a user of the computer (11) is correctly authenticated.

Title: Digital amplifier
Inventor: DURBAUM THOMAS
IPC: H03F1/32
Filed: 2004-03-25
Abstract: Recently, the use of class - D audio amplifiers has become more and more widespread. In contrast to the generally employed class - AB linear amplification technology, class - D allows for improved efficiency. However, the class - D principle is known for its poor distortion characteristics. According to the present invention a digital amplifier (18) is provided for converting an audio signal to a power output, comprising a ripple suppression circuit (16) for suppressing voltage ripples in a supply voltage supplied to the bridge circuit with (6) at least one pair of switches. The ripple suppression circuit (16) suppresses ripples in the supply voltage supplied to a switch in the bridge circuit (6), which has been found to cause a major part of the distortions in the output signal of the digital amplifier (18).
