Non-destructive sideband reading of processor state information
A processor receives a command via a sideband interface on the processor to read processor state information, e.g., CPUID information. The sideband interface provides the command information to a microcode engine in the processor that executes the command to retrieve the designated processor state information at an appropriate instruction boundary and retrieves the processor state information. That processor information is stored in local buffers in the sideband interface to avoid modifying processor state. After the microcode engine completes retrieval of the information and the sideband interface command is complete, execution returns to the normal flow in the processor. Thus, the processor state information may be obtained non-destructively during processor runtime.

A proxy apparatus and method for streaming media information via at least one network and for building-up a good quality version of the media information.

Interval centroid based watermark decoder
An interval centroid-based watermark encoder encodes a watermark into a packet flow. Intervals are defined for the packet flow. Some of the intervals are selected as group A intervals while other intervals are selected as group B intervals. Group A and group B intervals are paired and assigned to watermark bits. A first or second value may be encoded by increasing the relative packet time between packets in either the group A (for the first bit value) or group B (for the second bit value) interval(s) of the interval pair(s) assigned to the watermark bits that are to represent the first or second bit value and the beginning of the same group interval(s). The relative packet times may be measured by a decoder and used to calculate a centroid difference for each interval pair. The centroid differences may be used to reconstruct the watermark.
Methods and systems for managing and exchanging digital information packages with bandwidth securitization instruments
Responsibility can be established for specific copies or instances of copies of digitized multimedia content using digital watermarks. Management and distribution of digital watermark keys (e.g., private, semiprivate and public) and the extension of information associated with such keys is implemented to create a mechanism for the securitization of multimedia titles to which the keys apply. Bandwidth rights can be created to provide for a distributed model for digital distribution of content which combines the security of a digital watermark with efficient barter mechanisms for handling the actual delivery of digital goods. Distributed keys better define rights that are traded between transacting parties in exchanging information or content. More than one party can cooperate in adding distinguished watermarks at various stages of distribution without destroying watermarks previously placed in the content. Additionally, the amount of information which any one party must divulge to another party can be minimized, and “downstream” parties can be prevented from compromising or otherwise gaining control of watermarks embedded by “upstream” parties.

A zoom lens optical system includes: a first lens group that is provided close to an object, has a negative refractive power in total, and includes an optical part having a surface that reflects light; a second lens group that has a negative refractive power in total; an iris; a third lens group that has a positive refractive power in total; and a fourth lens group that has a positive refractive power in total.
An imaging lens of which optical performance does not deteriorate even in a high temperature environment, various aberrations are well corrected, optical length is short, and back focus is sufficiently secured; the imaging lens comprising: an aperture stop S; and a junction type compound lens 14 having a positive refractive power, characterized in that the aperture stop and the compound lens are arranged in this sequence from an object side to an image side. The junction type compound lens comprises a first lens L1, a second lens L2 and a third lens L3, arranged in this sequence from the object side to the image side. The first lens and the third lens are formed of a curable resin material, and the second lens is formed of a high softening temperature optical glass material. The first lens and the second lens are bonded with adhesive, and the second lens and the third lens are bonded with adhesive. The object side face of the first lens and the image side face of the third lens are aspherical.
Zoom lens and image pickup apparatus
A zoom lens includes first to third negative, positive, positive lens groups. The second lens group includes first to fourth positive, negative, negative, positive lenses. The third and fourth lenses of the second lens group are bonded to each other to serve as a cemented lens. The zoom lens is configured to satisfy Conditional Expressions (1) and (2) as follows: −0.5
Zoom lens and image pickup apparatus including the same
A zoom lens includes a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, a third lens unit having a positive refractive power, a fourth lens unit having a negative refractive power, and a fifth lens unit having a positive refractive power. The first to fifth lens units are arranged in order from the object side to the image side. All of the lens units are moved during zooming from the wide-angle end to the telephoto end such that the distance between the first lens unit and the second lens unit is increased and the distance between the third lens unit and the fifth lens unit is increased. The refractive power of the fourth lens unit and the refractive power of the fifth lens unit are adequately set with respect to the zoom ratio.
Projection objective of a microlithographic projection exposure apparatus
A projection objective of a microlithographic projection exposure apparatus comprises a manipulator for reducing rotationally asymmetric image errors. The manipulator in turn contains a lens, an optical element and an interspace formed between the lens and the optical element, which can be filled with a liquid. At least one actuator acting exclusively on the lens is furthermore provided, which can generate a rotationally asymmetric deformation of the lens.
