  • Publication number: 20020184517
    Abstract: Digital rights management allows one or more of usage rights and delegation rights to be associated with a document. Through the use of the usage rights and the delegation rights, a hierarchy of rights associated with a document is created that provides a tree-type structure of rights extending from the content owner down through one or more users.

  • Patent number: 5938743
    Abstract: In the UNIX Operating System, modifying the kernel routine Physio, to enable a single system call to set up a number of concurrent direct memory access (DMA) channels between memory and the data buffers of a device. Many character device drivers use the UNIX Physio facility for I/O. The traditional implementation of Physio handles I/O in a serial manner by performing gather-write or scatter-read operations. This invention is an enhancement to Physio to support parallel I/O operations.

  • Patent number: 5329147
    Abstract: When a field effect transistor is used to control the current through an inductive load, the flyback voltage is felt through the vertical pnp transistor at the drain, which onducts to the substrate. This current represents a power loss and a source of heat. This invention supplies a second lateral transistor which conducts this current back to the power supply.
