Abstract: A system and method comprising a computer useable medium having computer readable program code means embodied therein for authenticating and encrypting and decrypting information transferred over a public network between a client application program running in a client computer and a server application program running in a server computer and a directory service application program running in a server computer. A method for obtaining a session master key by an application from a server includes sending an open request to the server for the session master key and receiving a first reply by the application from the server with a first portion of the session master key. The first reply identifies a directory server from which a second portion of the session master key may be obtained. The application sends an open request to the directory server specified by the server in the first reply for the second portion of the session master key and receives it from the directory server.

Abstract: A system and method comprising a computer useable medium having computer readable program code embodied therein for authenticating and encrypting and decrypting information transferred over a public network between a client application program running in a client computer and a server application program running in a server computer and a directory service application program running in a server computer. A method for secure communication by a processor with a server includes generating a message to the server by employing a one pass key generation probabilistic authentication process using a predetermined session master key and sending the message to the server. A method for secure communication between an application executable on a computer and a web server coupled to the computer includes participating by the application in an initial authentication process with the server and wrapping every GET and POST request message to the server in an SSLX-EA exchange after the initial authentication process.

Abstract: An apparatus for processing an analog signal includes a programmable signal converter in which a mapping between input voltages and output voltages is loaded into an input-to-output mapping device, e.g., one or more look-up tables. The resulting device has a lower cost, introduces a shorter delay, requires significantly less circuit board real estate, and has a higher operating frequency than the existing devices. An exemplary embodiment includes an analog-to-analog converter disposed in an integrated package or on a single chip integrated circuit that includes an input converter, an input-to-output mapping device and a digital-to-analog converter. The traditional encoding/decoding process on the output of the digital-to-analog conversion is replaced in this embodiment by using the input converter to drive address mapping values in the input-to-output mapping device, e.g., entries in a lookup table, thereby significantly speeding up the process.

Abstract: The present invention provides a method and apparatus for rendering an input video stream as a polygon texture. The method provides process steps to receive the input video data in a Mip Map generator, wherein the Mip Map generator converts the video data to Mip Map data and stores the Mip Map data in a first memory storage device; wherein the first memory storage device is located in a V buffer. The method further includes sending a data set from a Z buffer to V buffer and mapping the data set to RGB values at a texel address in the V buffer memory. The data set includes U, V and Z coordinates, Mip Map level and channel identification data. The V buffer includes a V buffer fetch module that receives the data set from the Z buffer and maps to RGB data within V buffer memory.

Abstract: An electrochemical gas sensor comprises: a working electrode for exposure to a gas to be sensed; a counter electrode having an outer periphery; a reservoir for electrolyte; wick means providing a path for electrolyte to pass from the reservoir, around a first part or parts of the outer periphery of the counter electrode to provide electrolytic continuity between the counter electrode and the working electrode; and a gas diffusion means providing a path for gas to diffuse to or from a second part or parts of the outer periphery of the counter electrode.

Abstract: An additional phosphor-excitation mechanism improves the light output of a visible-light emitting phosphor. One excitation mechanism indirectly excites the visible-light emitting phosphor by first striking a non-visible-light emitting particle (such as an ultra-violet-emitting phosphor) with an electron beam, which then emits non-visible radiation that strikes a visible-light emitting phosphor. The non-visible-light emitting particles can be disposed behind and/or adjacent to die visible-light emitting phosphors. A second mechanism directly excites the visible-light emitting phosphor by directly striking the visible-light emitting phosphor with an electron beam. Thus, the same visible-light emitting phosphor is activated by the first indirect mechanism as well as the second direct mechanism.

Abstract: The invention relates to a process for continuously perforating in a wellbore comprising the following steps of determining a location to be perforated in the wellbore proximate an oil formation; placing an apparatus comprising a plurality of charges to said location in the wellbore; and continuously conducting perforation at said location with said charges in the apparatus. The invention also provides an apparatus for specifically performing the process, which comprises a transmitting system, a positioning system and a controlling system. The process and the apparatus can be used in a poor condition of the formation.

Abstract: A deflection yoke for use in a cathode ray tube includes a switching circuit, which is coupled to each vertical coil. The deflection yoke employs two pairs of vertical coils. The vertical coil pairs can be two pairs of saddle type coils, one pair of saddle type coils and one pair of toroidal type coils, or a divided pair of saddle type coils to make two pairs of saddle type coils. The deflection in the first quarter region from the top and the last quarter region at the bottom of the CRT screen is provided by one coil when energized by the vertical deflection current switched through it. The deflection in the two middle quarter regions of the CRT screen is provided by a second coil when energized by the vertical deflection current switched through it. One vertical coil pair is optimized to correct convergence error in the top and bottom quarter portions of the CRT screen. The other vertical coil pair is optimized to correct convergence error in the middle portion of the CRT screen.

Abstract: A lightweight cathode ray tube is formed by reducing a cross-sectional area on the apeture grill tapes in the aperture grill. One exemplary embodiment of the reduced cross-sectional area aperture grill tape includes a central longitudinal channel in a side of the aperture grill tape that faces away from the screen. The reduction in cross-sectional area reduces a linear density of the tape thereby decreasing the tension required by the frame. As each of the aperture grill tapes includes this central longitudinal channel, the weight of the overall aperture grill is significantly reduced and the aperture grill frame weight is reduced due to the lower aperture grill tension. A method for producing the reduced cross-sectional area aperture grill tape is possible without significantly increasing the cost of manufacturing the aperture grill tape.

Abstract: A secure electronic digital streaming system provides absolute system security and user-defined message security for electronic digital streaming between two public entities. These digital streams can be of any kind provided the contents are created using binary (0 or 1) bits; the unique and total possible combinations of which will be defined in a master alphabet of 64 6-bit combinations. The system encrypts and decrypts source digital stream data using a series of message keys that are derived from a private, numeric original key known only by both parties sending and receiving streams. The message key suite absolutely secures the original key from discovery. The system translates digital stream content binary bits into numbers based on a message key suite dependent distribution of the master bit alphabet and then uses the related patent mathematics to encrypt the numbers. The formulas return every possible number value, except the input value, and are completely dependent on the message key suite.
