Abrégé

A system which, with data provided by one or more sensors, detects a user's alteration of the geometries of parts of his face, head, neck, and/or shoulders. It determines the extent of each alteration and normalizes it with respect to the maximum possible range of each alteration so as to assign to each part-specific alteration a numeric score indicative of its extent. The normalized part-specific scores are combined so as to produce a composite numeric code representative of the complete set of simultaneously-executed geometric alterations. Each composite code is translated, or interpreted, relative to an appropriate context defined by an embodiment, an application executing on an embodiment, or by the user. For example, each composite code might be interpreted as, or assigned to, a specific alphanumeric letter, a color, a musical note, etc.

Abrégé

A method for data exchange between a plurality of personal computing devices where a third party receives, stores, and transmits data between each of said personal computing devices, which involves providing a third party data sharing server connecting the personal computing devices, establishing an encryption/decryption module on each personal computing device connected to the data sharing server, generating a file encryption key and a file decryption key associated with and unique to an original data file using the encryption/decryption module of a first personal computing device associated with a first user, encrypting the original data file with the file encryption key for sharing with a second personal computing device associated with a second user selected by the first user and with a third personal computing device associated with a third user selected by the first user, encrypting the file decryption key with a first recipient encryption key unique to the second user to produce a first encrypted file decryption key, and encrypting the file decryption key with a second recipient encryption key unique to the third user to produce a second encrypted file decryption key. The method also involves transmitting the encrypted data file, forwarding the encrypted data file and the first encrypted file decryption key from the third party server to the second personal computing device, forwarding the encrypted data file and the second encrypted file decryption key from the third party server to the third personal computing device, decrypting the file decryption key using the encryption/decryption module of the second personal computing device to reconstitute the file decryption key from the first encrypted file decryption key and a first recipient decryption key, and decrypting the file decryption key using the encryption/decryption module of the third personal computing device to reconstitute the file decryption key from the second encrypted file decryption key and a second recipient decryption key.

Abrégé

A novel architecture for a data sharing system (DSS) is disclosed and seeks to ensure the privacy and security of users' personal information. In this type of network, a user's personally identifiable information is stored and transmitted in an encrypted form, with few exceptions. The only key with which that encrypted data can be decrypted, and thus viewed, remains in the sole possession of the user and the user's friends/contacts within the system. This arrangement ensures that a user's personally identifiable information cannot be examined by anyone other than the user or his friends/contacts. This arrangement also makes it more difficult for the web site or service hosting the DSS to exploit its users' personally identifiable information. Such a system facilitates the encryption, storage, exchange and decryption of personal, confidential and/or proprietary data.

Abrégé

A wave energy conversion apparatus is provided for converting wave energy to electrical or chemical energy. The apparatus includes a flotation device that is adapted to float on the surface of a body of water having a wave base. A Venturi tube is connected to the flotation device such that when the apparatus is in position in the body of water, the Venturi tube is positioned below the flotation device and at a distance below the surface of the body of water near or below the wave base. Water flows downwardly in a Venturi channel and through a constricted region when the flotation device moves upwardly by wave action in the body of water. Water flows upwardly in the Venturi channel and through the constricted region when the flotation device moves downwardly by wave action in the body of water. The apparatus also includes a turbine in the Venturi channel and at least one of a first extension cuff extending upwardly from the upper mouth and a second extension cuff extending downwardly from the lower mouth. The apparatus is relatively simple in structure, inexpensive to build and maintain, and is capable of producing large amounts of energy.
