Abstract: Techniques are disclosed for performing operations in an authentication token or other cryptographic device in a system comprising an authentication server. In one aspect, a code generated by the authentication server is received in the cryptographic device. The code may have associated therewith information specifying at least one operation to be performed by the cryptographic device. The cryptographic device authenticates the code, and responsive to authentication of the code, performs the specified operation. If the code is not authenticated, the operation is not performed. The code may be determined as a function of a one-time password generated by the authentication server. The function may also take as an input an identifier of the operation to be performed.

Abstract: A method for process control, said method comprising: (a) providing a computational fluid dynamics model of a first process, (b) inputting to the computational fluid dynamics model data on the feed to said first process, said data representing the situation at an initial time t0, such that the model generates a real-time simulation of one or more properties of said first process at a future time, t2, and (c) using the simulation for control of said first process or for control of a second process to which the first process is linked.

Abstract: A multimedia device or other type of processing device comprises a memory, a processor coupled to the memory, and playback circuitry coupled to the processor. In one aspect, the processor is operative to control the storage in the memory of at least one multimedia file containing a one-time password or other type of password, where the password is generated externally to the processing device, and to control the playback of the multimedia file via the playback circuitry to make the password apparent to or otherwise accessible to an associated user or other entity. The multimedia file may comprise, for example, an audio file, with the password being presented to the user in an audible form upon playback of the audio file. As another example, the multimedia file may comprise a video file, with the password being presented to the user in a visible form upon playback of the video file.

Abstract: A method of allowing a user to authenticate to an authentication service while isolating information associated with the user from the authentication service includes generating a service user identifier (SUID) associated with an authentication code source, a subscribing site and an authentication service. The method includes creating an association of the SUID with the information associated with the user, and isolating the association within the subscribing site. The method includes providing an authentication code generated by the authentication code-generating device from the user to the subscribing site, and providing the authentication code along with the SUID and information identifying the subscribing site to the authentication service.

Abstract: An irrigation control system for land comprising: (a) at least one meter to measure one or more wheather conditions in a first area; (b) at least one monitor to (i) examine rainfall data derived from a radar scanning at least the first area according to pre-determined criteria and (ii) to extract data which is representative of the scanned rainfall in a subarea of the first area; (c) a store to store the extracted data; and (d) a controller connected directly or indirectly to the meter and the monitor and to the store, to calculate a moisture content value for the subarea and a predetermined moisture content value for the sub-area, and to regulate the irrigation in a sub-area.

Abstract: The present invention comprises of a circular prism having beveled periphery and center faces cooperating with multiple other prisms to form a light capacitor. The present invention allows a user to collect and hold the light in a storage-type device for use in a concentrated way when desired.

Abstract: A method of forming an elongated decorative trim strip of thermoplastic material with an end of the strip having a desired shape of non-constant cross-section in planes perpendicular to the longitudinal axis of the strip. An extruded length of thermoplastic material is first made of a length substantially equal to the desired length of the decorative trim strip with a first longitudinally extending surface of the length being a front show face and a second longitudinally extending surface opposite the first surface being a back mounting surface. At an end portion of the extruded length, material is removed inwardly from the second surface to create a cavity behind the first surface while leaving the show face generally undisturbed.
