Abstract: Controlling unauthorized access to software distributed to a user by a vendor. A verification key is generated by a product key generator and either embedded in the software prior to distribution or packaged with the software as a self-installing package. The verification key includes a public verification key. The combination of the software and the verification key create distributable software which is distributed to a user. The user installs the software on a user computer system as protected software. To obtain a user key, the user inputs identifying information, which may be for the user or for a group, which is sent to a user key generator. The user key generator converts the identifying information to a numeric representation and then generates, by signing the numeric representation with the private signing key, a user key, which is returned to the user.

Abstract: A light source for a scrolling color illumination system includes a lamp (212) producing light, first and second independent reflectors (220, 230) each receiving a portion of the light from the lamp (212), and a light guide (260) receiving two independent images of the light source created by the portions of the light received by the first and second independent reflectors (220, 230). Through such an arrangement, the light guide (260) provides a light beam at an output thereof having an aspect ratio that is twice an aspect ratio of the light beam produced by the lamp (212) while preserving its original etendue. Beneficially, a polarizing element (266) polarizes the unpolarized light beam from the light guide (260) and, in the process, the aspect ratio is further doubled, again without an increase in the etendue.

Abstract: The invention relates to a gear for conveyors which has a drive shaft to which a drive motor is to be fastened as well as an output shaft with which the gear is connected to the conveyor. However, at least one gear step is provided within the gear. Moreover, the gear is provided with a freewheel locking in one direction of rotation. A second gear step is provided in this case between the freewheel and the elements transmitting torque between drive and output shaft during normal operation, so that the freewheel should be operated at a higher speed and must only provide a low holding moment in the event of a stoppage.

Abstract: A method for setting priority levels in a multiprogramming computer system (1) with priority scheduling, in which threads (15, 16, 17) of execution of each process (13, 14) have a standard priority level, comprises measuring relative use of one or more processors (2) in the system (1) by the threads (15, 16, 17) of execution of a process (13, 14). The priority levels of one or more threads (15, 16, 17) of execution are lowered if their measured relative use exceeds a certain escalation threshold for the duration of an escalation time period (?T1.

Abstract: An optical apparatus comprises a reflective liquid crystal (LC) panel, and an optical device. The LC panel includes a twisted-nematic (TN) LC material, wherein one mode of the LC material includes a 90 degree twist (90TN0). A color sequential light valve may incorporate the LC material with the 90 degree twist (90TN0). The LC panel beneficially exhibits a contrast of at least approximately 1000:1. Moreover the LC panel exhibits minimal divergence between transfer characteristics for different colors of the optical system. Furthermore, the LC panel provides a higher contrast and superior uniformity in both dark and bright states, compared to known LC devices. Finally, the use of retarders in LC-based systems may be minimized or eliminated using the LC panel.

Abstract: A method for protecting a variator in a continuously variable belt-type transmission of a motor vehicle, simultaneously with a calculation based on an engine signal containing the magnitude of the engine torque and subsequent conversion of a contact-pressure theoretical value, providing the added safety on the variator, that the contact pressure on the variator is measured by a pressure sensor and the maximum transmissible transmission input torque is calculated with reference to this value. The maximum transmissible transmission input torque is then compared with the engine torque to the transmission and in case the maximum transmissible transmission input torque is less than the engine torque, an engine interruption is effected.
