摘要： A monitoring system monitors a pressure wave developed in the surrounding ambient environment during inkjet droplet formation. The monitoring system uses either acoustic, ultrasonic, or other pressure wave monitoring mechanisms, such as a laser vibrometer, an ultrasonic transducer, or an accelerometer sensor, for instance, a microphone to detect droplet formation. One sensor is incorporated in the printhead itself, while others may be located externally. The monitoring system generates information used to determine current levels of printhead performance, to which the printer may respond by adjusting print modes, servicing the printhead, adjusting droplet formation, or by providing an early warning before an inkjet cartridge is completely empty. During printhead manufacturing, an array of such sensors may be used in quality assurance to determine printhead performance. An inkjet printing mechanism is also equipped for using this monitoring system, and a monitoring method is also provided.

摘要： Methods and systems for allowing customer or third party testing of secure programmable code are disclosed and may include verifying code loaded in a set-top box utilizing a test hash or a production hash prior to execution of the code, where the test hash and production hash may be stored in a memory, such as an OTP, within the set-top box, and may allow migration from corresponding test code to production code, which may be verified utilizing the test hash and production hash, respectively. The test and production hashes may be customer specific. The migration from test code to production code may be authenticated using at least a set-top box specific password. The test hash may be stored in a first portion of a one-time programmable memory and the production hash in a remaining portion, with the first portion being less than or equal to the remaining portion.

A security processor may comprise multiple security components and may support multiple user modes. For each user mode supported, at least one access rule table may be generated to indicate access rules to a security component in the security processor. An access control list comprises information regarding the access rules for a particular user mode to the security components in the security processor. An access control matrix may be generated based on the access control lists for the user modes supported by the security component. The access control matrix may be implemented and/or stored in the security processor for verifying access rights of a user mode.

摘要： The present invention is directed to a system for demultiplexing video signals that have been combined using a time division multiplexing approach. The system includes synchronizers, parsers, demultiplexers, and an input buffer. Each demultiplexer within the system includes a header detect module, a slot map module, a frame sync module and a packet accept module. The method includes the steps of receiving an input stream that contains data packets for more than one program channel that have been combined in which packet identification (PID) information is used and a time division multiplexing scheme, such as transport stream multiplexing format (TSMF) is used. The PID and slot location for each packet is analyzed. Based on the PID and slot location a packet is either accepted or rejected.
