A system, method, and program for managing a user key used to sign a message for a data processing system having an encryption chip are disclosed. A user is assigned a user key. In order to encrypt and send messages to a recipient(s), the messages are encrypted with the user key. The user key, in turn, is encrypted with an associated key. The associated key is further encrypted using an encryption chip key stored on the encryption chip. The encrypted messages are communicated to a recipient to validate an association of the user with the encrypted messages. The associated key is decrypted with the encryption chip key. The user key is decrypted with the associated key, and the messages are decrypted with the user key. Thereafter, validation of the association of messages with the user is removed by revoking the associated key. In a preferred embodiment, encryption resources are centralized in a server system having the encryption chip. The server system is coupled to and provides encryption services to a plurality of client systems. Messages to be encrypted are sent from a user's client system to the server system, which encrypts the messages using the encryption chip. The encrypted messages are sent from the server system to the client system, which then transmits the encrypted messages to their intended recipient(s). All data relating to the encrypted messages are erased from the server system after the encrypted messages are sent from the server system to the client system.

A method and system is provided for capturing, organizing, and presenting information generated from a television program. The method monitors closed caption data of television programs for transition symbols and user defined search parameters and scheduling information. Information relating to captured television programs is entered into a capture management database for assembly into an interactive results file. The interactive results file allows a user to browse, view and navigate the captured television program information.

Method and system for interactively capturing organizing and presenting information generated from television programs to viewers

A computer, and particularly a mobile client computer system, in which flexibility in use of the system is enhanced by a capability of receiving and dynamically recognizing a variety of what are here called docking options. Docking options are peripheral devices, such as radio transceivers, which can be selectively connected to and used with a mobile client system. A docked option is identified by an exchange of signals between the system and the option, accomplished through a plurality of input/output ports which together define an interface to the option.

Mobile client computer interacting with docking device

A computer system, and particularly a handheld mobile client system, in which a user input device such as a keyboard or a scanner, coupled by a tethering conductor or a wireless link such as an infrared radiation link, functions as a master while the central processing unit of the system functions as a slave in receiving input digital signals.

A new fiber optic connector housing and a new fiber optic receptacle, both of which conform to a new standard proposed by the X3T9.3 committee of the American National Standards Institute, are disclosed. In addition, four accessory devices for electro-optic modules, each of which includes one or more essentially conventional plug frames which fit into either one or more conventional, individual fiber optic connector housings or the new fiber optic connector housing, are disclosed.

Fiber optic connector housing

An optoelectronic assembly which provides for enhanced alignment between the internal components thereof. The assembly includes a housing having a base portion and a cover portion, the housing including therein a circuitized substrate. A pair of optoelectronic devices (transmitter and receiver components) are initially movably (loosely) positioned within the housing. The invention utilizes an alignment member which is secured to the housing while positively engaging the movably positioned devices and precisely align these devices with respect thereto such that these devices are in turn precisely aligned with optic means (e.g., a duplex optical connector) when the optic means is positioned within the alignment member. In one embodiment, the housing is of metallic material while the alignment member is a molded plastic structure. The alignment member may also include shutter means therein for safety purposes.
