摘要： When the intensity of visible light is properly modulated, the difference between the modulated visible light and the original visible light is not noticeable to human eyes but detectable to electronic devices. Thus, the modulated visible light may be utilized to form patterns that are only recognizable to electronic devices but not to human eyes.

摘要： Technologies are generally described for methods and systems effective to generate modified content data. In some examples, the methods may include obtaining, by a processor, identification data associated with an identification. The processor may generate offset data using the identification data, where the offset data may include an indication of the identification. The processor may determine first position data that may be effective to define a first position of a first object and a second position of a second object in a source document that corresponds to source content data. The processor may generate second position data using the offset data and the first position data. The second position data may be effective to define a third position of the first object and a fourth position of the second object. The processor may generate the modified content data by application of the second position data to the source content data.

摘要： Technologies are generally described for systems, devices and methods relating to blood pressure monitors. Blood pressure monitors may include a processor and a structure effective to be in communication with the processor. The structure may be effective to apply pressure to an object. Blood pressure monitors may include at least one photoreceptor effective to be in communication with the processor. Photoreceptors may be located in the device so as to be effective to detect light returned from the object while the pressure is applied. Blood pressure monitors may be effective to determine color values of the returned light, determine changes in the color values of the returned light, and determine a blood pressure based on the changes in the color values.

摘要： In an example biometric authentication system, a light beam generator may be configured to generate a light beam. The light beam may be projected to a retina of a user's eye and reflected from the retina. The reflected light beam may be directed, by an optical system, on to a holographic medium to form an input image. An image sensor may be configured to detect or sense the input image and further transmit the input image to an authenticator. The authenticator may be configured to compare the input image with a reference image and grant authentication for the user when the input image is determined to substantially match the reference image.

摘要： The present embodiments provide methods for detecting errors and vulnerabilities in software without access to its source code. The method entails extracting functions from dynamically linked applications, determining error return codes and error numbers for the extracted functions, and forming a wrapper using the extracted functions. The wrapper is used to intercept some of the function calls, wherein the intercepted functions are manipulated to fail. The embodiments further relate to an article of manufacture to detect errors. The article of manufacture utilizes an extraction module to extract functions from dynamically linked applications, software to compile error return codes and error numbers for functions, and a wrapper module to form a wrapper with the extracted functions.

摘要： In an Internet Protocol Television (IPTV) system, an IPTV server is configured to receive a request from an IPTV content storage device (CSD) to view a video stream. The IPTV server selects a set of peers for the IPTV CSD, and transmits the set of peers to the IPTV CSD. In the system, a capacity of a fiber to the node (FTTN) switch in a down linking direction is greater than or equal to a sum of a number of simultaneous viewers supported by the FTTN switch plus a number of viewers that receive video streams from peers in the same community.
