Abstract: A method and system is used to determine the correct rounding of a floating point function. The method involves performing the floating point function to a higher precision than required and examining the portion of extra precision in the result known as the discriminant. If a critical pattern is found in the discriminant, this indicates that standard rounding may give an incorrect result and further calculation is needed. The method can work for various rounding modes and types of floating point representations. The method can be implemented in a system as part of a processor instruction set or any combination of hardware, microcode, and software.

Abstract: A system and method for redeeming a coupon. The method includes determining that a coupon is valid, determining that the valid coupon is still available for use, and determining that the available valid coupon is tied to a user. The method additionally comprises determining that an ID for the user matches an ID for the user stored for the available valid coupon, and adding the available valid coupon to an order by the user to redeem the coupon.

Abstract: Method and apparatus for reducing a number of storage elements in a synthesized synchronous circuit. In one embodiment, the circuit is represented as a directed, partitioned graph. The graph is divided into a plurality of time-ordered timeslots that are bounded by storage elements. The strongly-connected components (SCCs) in the graph are first identified. For each middle SCC where there is slack between the middle SCC and a first SCC and slack between the middle SCC and a second SCC, a time-slot-relative direction is selected for moving the middle SCC. The direction is selected as a function of a number of storage elements required for moving the middle SCC toward the first SCC versus moving the middle SCC toward the second SCC. The middle SCC is then moved in the selected time-slot-relative direction.

Abstract: A method is provided of setting the voice personality of a voice service site. A user browsing a voice web visits a voice site where the voice output of the site is presented using a set of voice personality characterisers with which the user is particularly comfortable. The user, in subsequently transferring to another voice service site, opts to have the voice personality that was embodied in the set of voice personality characterisers used by the site being left, transfer with the user to the new site. This transfer will typically be subject to permissions set by both the site being left and the site about to be visited.

Abstract: A process for executing a downloadable service with specific access rights to at least one profile file in a user's computer. The web browser is used for accessing a web server through a first set of communication port and socket. Therefore is arranged a confined runtime environment such as for example an extended sandbox (11) and used in Java programming which Is assigned a second communication port and s ockets and which is used for executing downloadable service with restricted access on at least one profile file. The process can be used for executing services under the form of a signed archive file which signature is used for both validating the archive file and for selecting one particular secure class loader prior to the generation of the compiled code of the service.

Abstract: A seedable pseudo-random number generator. A linear feedback shift register (LFSR) arrangement is used to generate a first pseudo-random number, and a cellular automata is used to generate a second pseudo-random number. The bits of the LFSR arrangement are XORed with bits of the cellular automata to generate the output pseudo-random number.
