Granted: 2010-12-21
Abstract: After a processor (133) controlled system having communications (145) capabilities is delivered to a user in its generic configuration, customization of the system is realized in accordance with the invention by downloading thereto selected information objects, e.g., software components (135) and/or data, from a server.  To avoid unauthorized (145) downloading of the selected information objects, certain information in a request for the objects by the system to the server (152) is encrypted and/or cryptographically signed. Such information may be e.g., a serial number (129) identifying the system. If the server succeeds in decrypting the encrypted information and/or authenticating the digital signature, and thereby verifies the identity and legitimacy of the system (139), the server downloads the selected information objects to realize the customization.

Abstract: Un téléphone sans fil possède une unité de commande (120) de courant de sortie servant à poser une limite à la puissance maximum d'émission, qui est suffisante pour opérer un rejet de puissance vers une voie contiguë (ACPR). Pendant le fonctionnement de la pile, la limite n'est pas fixée. Elle dépend, au contraire, de la puissance émise réelle (114), ainsi que, de préférence, de la température (418) et de la tension (420) de la pile. Des signaux analogiques provenant de détecteurs pour chacun de ces paramètres sont multiplexés (406), numérisés (408) et appliqués à un microprocesseur (410). Ce microprocesseur applique un algorithme de limitation approprié extrait d'une table de consultation calculée de façon empirique. Le signal obtenu (430) limite le signal (118) de commande de courant reçu depuis la station de base. Si l'unité de commande (120) détecte (422) une alimentation en courant provenant d'une source extérieure plutôt que de la pile, le signal de limitation (430) est fixé par le microprocesseur (410).

Title: Discharge lamp lighting device and system using discharge-lamp lighting device
Inventor: NOGUCHI TOSHIYUKI
IPC: G03B21/00
Filed: 2002-03-04
Granted: 2006-12-12
Abstract: A discharge-lamp lighting device is provided which decreases arc jumps, suppresses the fluctuation in brightness of the lamp, and prolongs a life of the lamp, by positively accelerating growth of spots even when an inexpensive, small and highly efficient lamp is used. A discharge-lamp controlling portion (101) sets frequencies of drive-controlling signals (A a nd B) for drive-controlling a commutator (109) within a predetermined frequen cy range so that spots formed by arc discharge on electrodes composing a high-pressure discharge lamp grow through a cycle of oxidation-reduction of a metal composing the electrodes, and superimposes a triangular wave signal generated on the basis of the drive-controlling signals onto a current-controlling signal (F) over an entire period of the drive-controllin g signals so as to make a peak value of the triangular wave constant, thereby adjusting the waveform of current flowing in the high-pressure discharge lamp.
