摘要:
A field programmable gate array (FPGA) device including a non-non-programming-based default power-on electronic configuration. The non-non-programming-based default power-on electronic configuration defines a default state to initial a first logic function. Upon power-up, the FPGA device would be enabled to enter the default state without having first to be configured via a conventional programming mode, thus saving precious processing time during power-up. Several embodiments are disclosed, such as a mask via circuit, an asynchronized set/reset circuit, an unbalanced latch circuit and a flush and scan circuit. A related method is also disclosed to reduce the memory size dedicated to the first logic function to facilitate further programming after power-up. In addition to time saving and further programming, the FPGA device can also allow partial or incremental programming to expand the full functionality to match customer's different needs.

A system and method are disclosed for securely handling data and information that may be used by an electronic information system. This includes storing and accessing data on a medium that has the appearance of a standard CD or DVD, but is novel in comparison thereto as to its structure and content. The system and method may be embodied in media that have characteristics of a CD or DVD but can take any shape permitted for a CD or DVD. Further, the system and method may be used for interconnection of electronic devices without the need of cables or conventional wireless connections. And, the system and method may provide for secure storage of data or information downloaded from a source, such music from the Internet.
摘要:
A method for protecting a dynamically reconfigurable computing system includes generating an encoding signature and passing the encoding signature, through a system level bus, to at least one field programmable logic device and to a function library included within the system. The function library contains a plurality of functions for selective programming into the at least one field programmable logic device. A lock is generated so as to prevent external resources with respect to the system from accessing the encoding signature during the passing thereof.

摘要:
A system and method are disclosed that may used to significantly reduce the costs of printing documents. This will involve the use of remanufactured printer cartridges and printing only changed pages after the first printing of a particular document. The system and method also will permit an accurate determination of printing costs based on the incremental price of the paper and the cost the ink/toner necessary for printing each page of a document. The system and method may be carried out in a computer-based system with a connected printer, and the computer-based system connects to a central system.

A table comprising a table base and a tabletop is disclosed. The table base comprises a top surface comprising a rotatable portion comprising one or more permanent magnets. The rotatable portion rotates independently from the table base. At least a portion of the tabletop comprises a ferromagnetic material. The tabletop further comprises a usable first side and a usable second side alternately mounted to the table base by an attractive force between the ferromagnetic material and the one or more permanent magnets. Rotation of the rotatable portion of the top surface, such that the one or more permanent magnets are oriented away from the ferromagnetic material, engages or disengages the attractive force.

A liquid electrolyte fuel cell comprises means to define an electrolyte chamber (208), and two electrodes (10), one on either side of the electrolyte chamber (208), each electrode comprising:—a sheet (11) of metal through which are defined a multiplicity of through-holes (14), and—a gas-permeable layer (16) of fibrous and/or particulate electrically-conductive material which is bonded to and in electrical contact with the sheet of metal (11), and which comprises catalytic material (18). The electrode (10) may be arranged such that the gas-permeable layer (16) faces the electrolyte chamber (208).
摘要:
A system, method and program product for retaining a logic state of a processor pipeline architecture are disclosed. A comparator is positioned between two stages of the processor pipeline architecture. A storage capacitor is coupled between a storage node of the comparator and a ground to store an output of the early one of the two stages. A reference logic is provided, which has the same value as the output of the early stage. A logic storing and dividing device is coupled between the reference logic and a reference node of the comparator to generate a logic at the reference node, which is a fraction of the reference logic, and to retain a logic state of the information stored on the storage capacitor. Further mechanisms are provided to determine validity of data stored in the logic storing and dividing device.
摘要:
A method for increasing the manufacturing yield of field programmable gate arrays (FPGAS) or other programmable logic devices (PLDs). An FPGA or other PLD is formed in several sections, each of the sections having its own power bus and input/output connections. Each section of the FPGA or other PLD is tested to identify defects in the FPGA or other PLD. The FPGA or other PLD is sorted according to whether the section has an acceptable number of defects. An assigned unique number for the FPGA or other PLD chip or part identifies it as partially good. Software for execution and configuring the FPGA or other PLD may use the unique number for programming only the identified functional sections of the FPGA or other PLD. The result is an increase in yield as partially good FPGAs or other PLDs may still be utilized.
