The present invention provides methods and systems for authenticating identification documents. We also teach an identification document including two or more digital watermarks. The watermarks correspond with each other or with indicia carried by the identification document. The correspondence can be verified to determine authenticity. We also provide digital watermark detection methods and systems to identify the different watermarks through embedded orientation components. We then focus watermark message-decoding efforts on areas identified as likely including watermark orientation components. In another implementation we provide a watermark detection trigger to identify so-called legacy documents. The trigger may indicate the presence or expected absence of a digital watermark. In other implementations we provide a versatile document authenticator to toggle between watermarking and non-watermarking authentication processes depending on a detection trigger. Other implementations are provided as well.

The present invention relates generally to digital watermarking and steganographic encoding. One claim recites a method including: receiving data corresponding to at least a portion of digital data; separating the data into a plurality of portions; determining a measure relative to a predetermined measure for each of the portions, wherein the measure comprises a measure related to a predetermined digital watermark signal; based at least in part on the measure, identifying which out of the plurality of portions are likely to host digital watermarking therein. Of course, other combinations are provided as well.

This invention relates to a security apparatus for trade show booths comprising a flexible cover section to enclose an opening in a booth structure and a means for securely fastening the edges of the cover section to an opening of a booth structure so as to provide a securable removable cover to deter individuals from stealing merchandise from a display booth or otherwise enclose the booth for privacy. In one embodiment, adjustable fasteners that are used to secure the vertical edges of the cover are provide in manner that does not permit removal from outside of the cover when installed. Optional hangers are also used to hang the top edge of the cover to a support structure. Additionally, the cover may be provided with an adjustment belt to ensure that the cover remains taut on the support structure when locked in its fastened position.

In one embodiment, adjustable fasteners that are used to secure the vertical edges of the cover are provided in a manner that does not permit removal from outside of the cover when installed. These fasteners may comprise a hooked end, an arc-shaped engagement end and a tightening member between said hooked end and engagement end which work together to secure the vertical edges of the cover.

A disk to be installed on a dumbbell around the middle bar and adjacent the weight at one end to protect the user's hand(s) from contact with the weight. A slot allows the disk to be installed without removing the weights. A cavity on the weight side of the disk provides clearance for the shoulder or collar which hold the weights in position on some dumbbells. The inner surface of the disk is convex while the outer is generally planar to lie flat against the weights.

A securable cover apparatus for trade show booths comprising a flexible cover; a fastener mount attached to the flexible cover and a securable fastener having a rotating handle potion and a locking pin that is controlled by the handle portion. The fastener further includes a bracket wall with two guide members that are used to guide the fastener into a channel of the frame of the booth support structure. The securable cover apparatus is able to secure a trade show booth having a frame when the extending guide members of the securable fastener are slid between an opening in the frame and the locking pin is extended and rotated such that the frame of the tradeshow booth is positioned between flanges at the head of the locking pin and the bracket wall.

The present invention is a portable personal product caddy and usage apparatus which is constructed to accommodate a personal product container and its associated tool. The apparatus body is sized to the personal product container to be used with a holder that accommodates the associated tool for storage when not in use.

A database has a plurality of entries and a plurality of attributes common to each entry, where each entry corresponds to an individual. A query q is received from a querying entity query q and is passed to the database, and an answer a is received in response. An amount of noise e is generated and added to the answer a to result in an obscured answer o, and the obscured answer o is returned to the querying entity. Thus, a level of protection of privacy is provided to each individual represented within the database.

A method of storing and tracking digitally-encoded material includes associating a unique identifier with the digitally-encoded material, associating one or more built-in functions with the digitally-encoded material so that the unique identifier and the built-in functions are coupled to the digitally-encoded material. The built-in functions can govern transforms and rendering of the digitally-encoded material. The tracking is performed by associating a history of the digitally-encoded material with the digitally-encoded material. The history can be associated with the digitally-encoded material or kept in a database that communicates with the digitally-encoded material via the identifier. The built-in functions enable the digitally-encoded material to be stored in RAM in an encrypted form. A method for tracking can include encrypting a combination including the digitally-encoded material and the unique identifier and appending built-in function source code and the encrypted combination to form an executable entity executable independent of any particular operating system.

Disclosed are methods, devices, and media for enforcing network access control, the method including the steps of: extracting a packet signature from a packet (or packet fragment) received from a network; storing the packet signature and the packet in a buffer; computing a buffer signature using a per-endpoint secret key; determining whether the packet signature and the buffer signature are identical; and upon determining the packet signature and the buffer signature are identical, transmitting the packet to a protocol stack. Preferably, the step of extracting includes extracting the packet signature from a field (e.g. identification field) of a header of the packet. Preferably, the method further includes the step of: upon determining the packet signature and the buffer signature are not identical, discarding the packet. Methods for receiving a packet from a protocol stack, and transmitting the packet to a network are disclosed as well.

Disclosed are chimeric HPV L1 proteins and virus like particles comprising the same which are capable of generating high titer neutralizing antibody responses against at least two HPV types. The disclosed chimeric HPV L1 proteins and VLPs are useful as therapeutic and prophylactic reagents, as well as reagents for diagnosing papillomavirus infection.

A belt winch may be formed from stretchy fabric, includes a front panel joined to a rear panel. Flaps may be provided to form interior pockets, which are further formed by stitching or other joining techniques. Internal stiffening and resilient members may be incorporated between the panels at each end, aiding in the structure of the opposing ends of the belt which tie together.

A module air curtain and recirculation system that can be incorporated into various tables and workstations that provides 1) an effective air curtain between individuals, 2) a reduction of harmful viruses and 3) the ability for two or more people to be in close proximity without having to wear personal protective equipment such as face masks.

A fire protective barrier for a residential floor and a method of its construction, the construction involving a floor supported on lightweight joists of a type susceptible to early failure once exposed to a fire existing in the space below the floor, an array of elongated steel main tees suspended below the joists, the tees being parallel and spaced apart by a nominal distance of 2′, the tees having an upper hollow reinforcing bulb, a central vertical web extending downwardly from the bulb and a horizontal flange extending laterally from both sides of the web, drywall panels carried on upper faces of the flanges of adjacent pairs of tees, the drywall panels having a width of slightly less than the center-to-center distance of the tees, a majority of the panels having lengths of 8′ or more.
