Abstract: A Distributed management system for security of remote assets which provides security for widely distributed assets while at the same time providing great flexibility for a multiplicity of authorized persons without passcodes or personal keys to access multiple assets. The system has great flexibility by separating the lock and Key function and provides complete history of Key-Lock operations of the asset in real time scenario. The system gives a comprehensive solution to the static or mobile asset located at remote location to the owner.

Abstract: Verifying the integrity of a received binary object by calculating a first displayable authenticator derived from an input binary object. The first authenticator is then attached to the input binary object, producing a first composite binary object, which is sent to a remote receiver. A second composite binary object is received back from the remote receiver, wherein the second composite binary object includes a received binary object, a received first displayable authenticator, and a second displayable authenticator. A third displayable authenticator is calculated, derived from the second composite binary object, then a display of the first displayable authenticator is compared to a display of the third displayable authenticator, and verification of the integrity of the received binary object is indicated by an exact match between displays of the first and third displayable authenticators.

Abstract: Included are embodiments for facilitating business to business commerce. Some embodiments include registering a supplier account for a business supplier on an online marketplace, wherein registering the account comprises receiving a catalog of items provided by the supplier, registering a purchaser account for a business purchaser on the online marketplace, wherein the business purchaser represents a business entity, and providing a user interface to facilitate purchase of the item by the business purchaser from the business supplier. Similarly, some embodiments include receiving an indication from the business purchaser of a purchase of the item and facilitating exchange of the item for a predetermined price between the business purchaser and the business supplier.

Abstract: A type of search engine (referred to as the “Get Engine”) receives one or more keywords, semantically formulates a question being asked from the keywords, generates specifications for the query, and searches a website index to determine websites that are likely owners of the answer to the question based on the query specifications and website classifications. The Get Engine determines a website that is most likely the owner of the answer based on credibility, searches the pages of the website using the keywords and additional keywords related to the query, retrieves the answer from the pages of the website, and receives feedback used in part to determine the credibility of the website.

Abstract: A new photopolymerizable material allows single-step, fast recording of volume holograms with properties that can be electrically controlled. Polymer-dispersed liquid crystals (PDLCs) in accordance with the invention preferably comprise a homogeneous mixture of a nematic liquid crystal and a multifunctional pentaacrylate monomer in combination with photoinitiator, coinitiator and cross-linking agent. Optionally, a surfactant such as octancic acid may also be added. The PDLC material is exposed to coherent light to produce an interference pattern inside the material. Photopolymerization of the new PDLC material produces a hologram of clearly separated liquid crystal domains and cured polymer domains. Volume transmission gratings made with the new PDLC material can be electrically switched between nearly 100% diffraction efficiency and nearly 0% diffraction efficiency. By increasing the frequency of the switching voltage, switching voltages in the range of 50 Vrms can be achieved.
