Patent CA-2354248-A1 (CA)
Inventor: HANNA STEPHEN DALE
IPC: G01R31/317
Filed: 2001-07-27
Abstract: A method and apparatus for tracing hardware states using dynamically reconfigurable test circuits provides improved debug and troubleshooting capability for functional logic implemented within field programmable logic arrays (FPGAs). Special test logic configurations may be loaded to enhance the debugging of a system using FPGAs. Registers are used to capture snapshots of internal signals for access by a trace program and a test multiplexer is used to provide real-time output to test pins for use with external test equipment. By retrieving the hardware snapshot information with a trace program running on a system in which the FPGA is used, software and hardware debugging are coordinated, providing a sophisticated model of overall system behavior. Special test circuits are implemented within the test logic configurations to enable detection of various events and errors. Counters are used to capture count values when system processor execution reaches a hardware trace point or when events occur. Comparators are used to detect specific data or address values and event detectors are used to detect particular logic value combinations that occur within the functional logic.

Title: A synchronous flyback converter
Inventor: SVARDSJO CLAES
IPC: H02M3/28
Filed: 1999-12-16
Abstract: In a continuous mode flyback converter having a synchronous switch (Q2) the drive pulse to the switch (Q2) on the secondary side is generated by an inverting buffer circuit being fed from the output voltage terminal. By usin g such an arrangement several advantages are obtained. Hence, the pulse generating circuit arrangement generates a drive signal to the synchronous switch which is independent of the input voltage and the drive losses can thereby be minimized.

Abstract: A method and apparatus for securing the game program software and related da ta files used by a gaming device and for authenticating such files during game startup and play. In one embodiment of the present invention, a verification  code is generated by the manufacturer for each software file and data file used by the game. The verification codes are stored in a non-volatile, tampe r- proof, read-only memory device, which is (in some embodiments) securely attached to the gaming device. On some or every download of the game softwar e and/or related data files into the gaming device, commencement of a game, or  on the occurrence of certain pre-defined events, the stored verification cod e is used to validate the game software and data files. In some embodiments, verification is performed automatically on a periodic basis without operator  or player action. Verification consists of calculating a live verification code for some or all of the software and data files present in the alterable  random access memory using the same method chosen to create the stored verification code. In some embodiments of the present invention, the verification code is the result of a hash function of trusted copies of each  software and related data file. If the live code matches the stored code for  every suspect file, then operation and play proceeds normally. If, however, one or more codes do not match, an error condition is declared, operation is  halted, and notification of the error condition follows.

Abstract: A card records data as an optically readable code.      A non-interference area is provided around the code to inhibit presence of only an interference image having an attribute causing an error during reading of the code. The code reader's CPU provides a code detection area to be used when a restoration section detects a code image from an image pickup area as a frame image stored in memory. This code detection area is determined based on an alignment error between the image pickup element and the code, and a specification of the code. The alignment error may result from the bottom of a slit which specifies a positional relationship between the code and the image pickup element to pick up the code.
