Abstract: A multiple game jukebox system includes a hard drive that is able to execute video game software designed for execution on a conventional home-based system. The hard drive embodies various partitions including multiple partitions, where each partition represents a video game DVD disk. In communicating with such a hard disk drive device using the existing DVD bus, a particular pattern of disk reads or seeks is utilized to cause the hard drive to serve alternative data on subsequent disk reads (other than what exists on the currently selected disk). A media serving device initially defaults to playing a disk that contains a game selection menu program. The menu permits a user to select one of multiple video games for play.

Abstract: Efficient statistical profiling in embedded computing devices, such as video games, uses a hybrid random distribution of sampling points for more accurate reconstruction of executing code. Transmission of only function start addresses and corresponding representation of the call graph data reduces the memory overhead and increases communication speed.

Abstract: Profile data collected through sampling is transformed and visually and interactively manipulated and displayed. In one scenario, the profile data is collected through statistical profiling of a program for a video game. The game program profile data is visually and interactively manipulated and displayed to visually present a dynamic behavior of the video game that shows correlation of impacts that the functions of the program have on the video game's performance. This allows the developer to identify inefficient sections of the program for optimization.

Abstract: An example gesture recognition system and method recognizes a gesture made using a handheld control device comprising an accelerometer arrangement. The example system and method involve a database of example gesture inputs derived from accelerometer arrangement outputs generated by making respective gestures with the handheld control device. Corresponding components of a current gesture input and the example gesture inputs in the database are compared using root mean square calculations and the current input gesture is recognized/not recognized based on results of the comparing.

Abstract: An example system and method of providing an input to a processor-controlled system uses a handheld control device comprising an accelerometer. The example system and method involve determining magnitudes of outputs of the accelerometer for one or more axes based on movement of the handheld control device and controlling the processor-controlled system based at least in part on a combination of the determined magnitudes.

Abstract: An example system and method is provided for filtering input values associated with movement of a hand-held control device. A current input value is compared with an average input value and, based on the comparing, an output value is generated in a range between the current input value and a prior output value.

Abstract: A motor control system employing a single Hall sensor 2 providing a position feedback signal to a control circuit 10 is disclosed. The control circuit includes a tach counter circuit 12, a ramp mode circuit 14, an interpolation circuit 16, and a commutation logic circuit 18. Drive signals are output to the motor windings by the commutation logic circuit 18. The control state defining the drive signals is advanced on the basis of the estimated rotor position. The estimate of the rotor position is determined by linearly interpolating between Hall signal transitions.

Abstract: A controller has a data compression unit and error correcting code unit which share a single common random access memory. The controller is connected between a host computer and a peripheral device such as a tape drive. A second order search for strings of data bytes is enabled or disabled to change the compression ratio, data throughput, and memory bandwidth constraints.
