摘要： A printing apparatus is disclosed which has various operating components, and which includes a single sensing means for sensing certain operational characteristics of the operating components to monitor the operational status thereof for the purpose of either providing an operator perceptible indication that a certain operational characteristic of one of the operating components is not in a condition for normal operation of the printing apparatus. The single sensing means includes a photo detecting means mounted on the inside surface of the cover of a housing for the operating characteristics of the printing apparatus, and an actuating means mounted on an ink cartridge which is mounted on and movable with a moving print head, such that the sensing means can provided an ink dication of whether the cover is open or closed, whether the ink cartridge is present or absent, whether the print head is in a proper position for commencing a normal cycle of operation, and in one variation of an alternate embodiment of the invention, whether there is sufficient ink in the ink cartridge for normal operation of the printing apparatus, and in another variation thereof, how much ink is in the ink cartridge at all times between full and insufficient for normal operation of the printing apparatus.

摘要： System and method for performing cryptographic operations include providing at least one processor for performing cryptographic operations, memory coupled to the processor for use in performing the cryptographic operations; and a storage component coupled to the processor for storing and retrieving information calculated and used in the cryptographic operations. The processor, memory and storage component are securely enclosed whereby direct access to the cryptographic operations is prevented. At least the processor is comprised in an integrated circuit. A first power source, which is external to the secure enclosure, is coupled to and supplies power to the processor, the memory and the storage component. A second power source, which is within the housing of the integrated circuit, is coupled to and supplies power to at least the processor. A switch is included for switching from the first power source to the second power source when the cryptographic operations are being performed and for switching from the second power source to the first power source when non-cryptographic operations are being performed.
