Patent number: 6802615Abstract: This invention provides a projector capable of correctly informing a user of replacement time of a lamp and significantly improving performance and operation reliability. A storage circuit is mounted in a detachable lamp unit for accommodating a lamp, and information on the lamp and so on are stored in the storage circuit. If the switch of a projector proper is turned on, a main circuit reads lamp operating time up to the last time from the storage circuit, and compares the read operating time to replacement time of the lamp stored in advance so that the light is emitted from the lamp if the operating time is less, and display for prompting the lamp replacement is performed if the operating time is more, and the light is emitted from the lamp thereafter. If the switch of the projector proper is turned off, the main circuit adds the operating time of this time to the operating time of the lamp up to the last time read from the storage circuit on turning on the switch and writes it to the storage circuit.Type: GrantFiled: May 13, 2003Date of Patent: October 12, 2004Assignee: NEC Viewtechnology, Ltd.Inventor: Takayuki Okada

Patent number: 6704872Abstract: The present invention provides an improved technology of preventing illegal use and execution of a software program provided to a computer system. More particularly, the present invention is directed to a Processor of a type in which a memory managing unit is installed therein to manage storing operation of code/data in main memory and includes, as one of instruction set, an execution permitting instruction to permit execution of a program code (application) in the main memory. The procedure of execution permitting instruction is defined by a microprogram and includes an authentication procedure for authenticating the right to use the program beside a procedure for setting predetermined data in the memory managing unit in this invention. Execution of the software program is permitted only when the authentication processing is completed successfully. Because the authentication operation is performed within the processor, it is almost impossible to monitor or detect it from the exterior.Type: GrantFiled: April 28, 1999Date of Patent: March 9, 2004Assignee: International Business Machines CorporationInventor: Takayuki Okada
