Abstract: A system for the authentication by a card-issuing financial institution of identifying information of a card-holding user of a public data network. The system includes a secure data entry device connected to the public data network and a gateway device connected to the public data network and to a private data network used for transmitting messages between financial institutions. The secure data entry device enables the user to enter identifying information of a card issued by the card-issuing financial institution, and transmits the identifying information in a secure manner over the public data network to the gateway device. The gateway device transmits the identifying information to the card-issuing financial institution and receives an approval response from the card-issuing financial institution over the private data network. The approval response provides authentication of the identifying information by the card-issuing financial institution.

Abstract: The surface of hydrophobically-modified smectite clays (i.e., organophilic clays) are modified using a hydrophilic polymer, wherein the hydrophilic surface-modification of a hydrophobically-modified smectite clay with a hydrophilic polymer, renders the organoclays adequately dispersible in water.

Abstract: A benefit agent encapsulated in a particulate-based encapsulant, and a method of manufacturing the encapsulated benefit agent, are disclosed.

Abstract: An organophilic clay for thickening hydrophobic liquids comprising a layered silicate material, surfaces of said layered silicate material modified by an amphipathic copolymer prepared from a first comonomer that generates a hydrophilic homopolymer that is essentially insoluble in a hydrophobic liquid and a second comonomer that generates a hydrophobic homopolymer that is soluble in a hydrophobic liquid, said organophilic clay containing at least 10% by weight water, based on the dry weight of the layered silicate material.

Abstract: A capacitive/resistive device provides both resistive and capacitive functions. The capacitive/resistive device may be embedded within a layer of a printed wiring board. Embedding the capacitive/resistive device conserves board surface real estate, and reduces the number of solder connections, thereby increasing reliability.

Abstract: A keypad is disclosed which has a plurality of keys (12) for the input of information. Each key has a first switch (80) and a second switch (90). The first switches (80) are all connected to a common electrical interconnection (120) and the second switches (90) are connected into a matrix electrical interconnection (62, 100). The microprocessor (66) detects a global signal on the common interconnection (120) and supplies scan signals to the matrix interconnection (62, 100) to enable detection of a particular key. The processor (66) may also selectively change the state of lines (62, 100) of the matrix and also maintain particular lines in a predetermined state by open drain ports of the processor to which the lines of the matrix are connected.
