摘要:
The invention provides a method of recovering from de-synchronization attacks includes registering original and altered digital content using nonlinear transformations to iteratively attempt to provide better-approximated registration. Approximation occurs at more than one level of granularity, by selecting among a greater number of possible transformation functions at each step. Transformations and comparisons might be conducted directly on pixel values, on coefficients for a set of basis wavelets, or on some transformation of the original and altered digital content. A human operator might assist this process, such as by suggesting transformations or providing evaluation of the degree of registration. Upon resynchronization, embedded identifying information in the original digital content is recovered.

摘要:
This invention is directed to cryopreservation of harvested mammalian tissues and living cultured tissue equivalents made by in vitro technology. The invention involves immersing a mammalian tissue or cultured tissue equivalent in a cryoprotectant solution, agitating the cryoprotectant solution and the immersed tissue to achieve effective penetration of the cryoprotectant solution into the tissue, and then freezing the tissue at a very slow freezing rate at 0.3.degree. C. or less/min. In the freezing step, extracellular ice formation is initiated by seeding. The cryopreserved tissue may be stored for indefinite periods of time prior to use. The cultured tissue equivalent is an in vitro model of the equivalent human tissue, such as skin or cornea, which, when retrieved from storage can be used for transplantation or implantation in vivo or for screening compounds in vitro.

A cable organization unit includes a housing. A tray is attached to the housing by at least one slide, and is movable between a first position and a second position relative to the housing. A hood is removably secured to the tray. A user may remove the hood from the tray to access adapters attached to a bulkhead on the tray. The tray may include a latch for securing the tray to the housing in the first position, and the hood may be removed from the tray while the tray is in the first or second positions. A retainer is optionally attached to the housing. The retainer includes an adjustable opening which may be reduced in size such that edges of the opening frictionally engage and hold a jacket of a cable passing therethrough.

摘要:
Digital media recognition without substantial user interaction, using information from personal digital libraries, or about users. Digital media recognition ambiguities resolved using that information, including: a preponderance of entries in the user's personal library, including specific songs, authors, or genres; a similarity relationship between the user's personal library and the corpus of a collective library; demographic or specific information about the user; equality to a song already present; earlier results in resolving ambiguities; location of a mobile system in a designated region; location in a designated place within a house; existence of any parental controls; whether the imported digital entertainment information is being imported in bulk as part of a collection; whether, according to a selected similarity metric for digital entertainment information, the imported digital entertainment information would be “closer” to one or more elements of the user's personal library.
摘要:
A method of embedding information in digital content representing media streams. The method includes (1) selecting a set of locations within that digital content representing the media stream to embed information, (2) selecting a set of possible alterations to make at those locations, and (3) making a subset of the possible alterations. The set of locations and possible alterations is herein sometimes called a “watermark.” The subset of actual alterations that are made is herein sometimes called a “fingerprint.” The method determines a set of locations at which there are alternative versions of digital content representing the same media stream, such as one being the original and one being an alternative version of the same digital content, herein sometimes called the “original movie” and the “alt-movie,” or herein sometimes called the “original block” and the “alt-block” for a particular block in the digital content representing the media stream.
摘要:
Embedding fingerprinting or watermarking information includes delivering information in-band within digital content representing a media stream, so unauthorized distributors must choose between degrading the media stream, or leaving sufficient information detectable that unauthorized distribution can be detected. For fingerprinting, the method provides a relatively high degree of confidence of both detecting at least one colluding unauthorized distributor, and not falsely accusing any innocent party of being an unauthorized distributor. Embedding fingerprinting or watermarking information includes selecting a sequence of locations within digital content, and embedding information in the form of a sequence of one or more bits at each of those locations, thus representing a set of marking symbols. Marking symbols cannot be readily manufactured without at least one colluding unauthorized distributor having received it, so any distributed digital content includes at least some marking symbols traceable to at least one colluding unauthorized distributor.
