Abstract: A system protects private information provided in an exchange between a client and a server. The system receives the private information from the client and determines whether it is of a type for which a guarantee may be issued. The guarantee provides an indemnity for the benefit of the client for misuse of the private information. The system then issues a guarantee for the private information, if it is determined to be of the type for which a guarantee may be issued, and provides the private information to the server with a guarantee.

Abstract: An insect repellent is provided and includes terpineol, citronella, and one or both of rhodinol extra and geraniol as actives provided in a conveying medium. The actives are used in small percentages, e.g. as little as 0.01%, preferably at between 0.05% and 0.08%, and preferably less than 1%, yet are synergistically efficacious, particularly against ticks carrying Lyme disease. The conveying medium can be a cosmetic moisturizer lotion, with or without a sun screen. For a spray, the conveying medium can be water or alcohol based. An attractive fragrance is preferably provided as approximately 0.4% of the insect repellent The lotion or spray is safely applied in liberal quantities to humans and animals without unpleasant side effects such as stinging.

Abstract: Insect repellent blends, lotions, and sprays are provided. The insect repellent blend includes citronella, geraniol, crystalline 3,8 P-menthanediol (Chinese crystal), and terpineol and/or rhodinol. Preferably, the blend is dissolved or dispersed in a conveying medium so that the resulting product has weight percentages of approximately 0.05% citronella, approximately 0.06% geraniol, approximately 0.08 to 0.5% crystalline 3,8 P-menthanediol approximately 0.06% terpineol and/or approximately 0.08% rhodinol (extra). Four embodiments were tested against the efficacy of the individual ingredients and against an inert control. The interaction of ingredients in each of the embodiments was found by statistical analysis to be synergistic. The embodiments containing higher concentrations of the crystalline 3,8 P-menthanediol were found to have greater efficacy than the embodiments containing lower concentrations of crystalline 3,8 P-menthanediol.

Abstract: A three dimensional optical data storage and retrieval system includes a three dimensional optical data storage medium and an apparatus for providing access to data stored on the medium. According to one aspect of the invention, the data storage medium includes a number of concentric shells each of which has a curvilinear data storage surface for storing data in a number of substantially parallel data tracks. According to another aspect of the invention, the data storage medium includes a number of data storage surfaces which are rotatable about a common axis, each data storage surface for storing data in a number of substantially circular data tracks and having an optically transparent window which transects each of the data tracks. Each shell or data storage surface preferably has a drive engagement portion for engaging a driver to rotate the shells or data storage surfaces individually about a common axis.

Abstract: A sealed battery is provided having three or more terminals, with at least one positive terminal on one end of the battery and at least one negative terminal on the other end of the battery. The extra terminal is coupled to a reserve portion of the cathode or anode, with the main and reserve portions of the cathode or anode being separated by insulation. The extra terminal may be located on the top, bottom, or side of the battery according to the various embodiments provided. Battery holders for accomodating the three terminal batteries are also provided. With three terminals, different types of switching may be utilized to bring the reserve into play automatically, or by manual or remote activation, and either in a parallel manner with the main cell, or independently thereof. The sealed batteries having three terminals are designed to be backward compatible so that they may be used in standard battery holders.

Abstract: A sealed battery is provided with a cathode, first and second anodes which are isolated by insulation, first and second current collectors which are separated by the insulation, and an integral switch. The cathode is coupled to a positive terminal of the battery, while the first current collector is coupled to the first anode and to the negative terminal. The second current collector is also coupled to the second terminal via the switch which is easily activated by hand manipulation or by use of a common object such as a ball point pen point. The cathode, first anode, and first current collector provide a large cell. When the large cell is exhausted, as indicated by the failure of the equipment which it is powering to function properly, the reserve cell comprised of the cathode, second anode, and second current collector is readily activated by manipulating the switch.
