摘要:
The embodiments described herein relate to amplifier circuits with power rails. The power rails are generated in response to an input signal, which will typically be an audio signal, and with a sufficient magnitude to power the amplifier and to generate an output signal corresponding to the input signal.

A watermarketing system and method is proposed for still or moving pictures in which a watermark is embedded robustly and simply into DC-values, but without causing unacceptable visible picture degradation. The watermark is secure and can be readily detected, and the method can be used to convey additional data. Also disclosed is a method for watermarking a sequence of pictures in which the visibility of artifacts is reduced. The watermark may carry data and may be used to label a programme.
摘要:
A method for executing trusted commands, in which a trusted command is first received from a user at a user terminal and parsed by untrusted code; then passed to a trusted computing base for execution. The trusted computing base displays some indication of what is to be done back to the user for confirmation. Confirmation of the commands prevents unauthorized modification of the commands and increases system confidence. A randomly (or pseudo-randomly) generated process identifier is employed to verify the existence of a trusted path.
摘要:
A system for automatically creating and maintaining a database of information utilizing user knowledge about sales related subjects. Described is an Internet-based system for assisting/motivating a population of users interested in information about certain categories of sales related subjects to automatically maintain the database content and to improve the usefulness and quality of the database information without any substantial management by the website owner-manager. The user opinions are primarily in the form of both comments and ratings of which sales-related subjects best provide assistance in completing a sale. Also a system for permitting users to access selected functions of the system for creating and viewing subjects from within other software applications.
摘要:
The invention relates to compounds of formula (I) pharmaceutical compositions containing the same as well as methods of treating patients suffering from a condition susceptible to amelioration by a Factor Xa inhibitor using the same.
摘要:
A system and methods to mutually satisfy a consumer with a discount and a vendor with a minimum number of sales by establishing a tipping point associated with an offer for a good or service. If the tipping point is met, the sale of the good or service is executed and the consumer is charged and receives an indication of the discounted sale, such as a certificate. If the tipping point is not met, the discount offer is abandoned and the consumer is not charged. Once the tipping point is established, the vendor receives a payment, even before the consumer uses the certificate.
