Abstract: A pair of cooling fans in an electronic system is operated synchronously at a common speed and with a particular phase relationship between their respective acoustic properties that minimizes the combined acoustic noise produced by the pair of cooling fans.

Abstract: A computer system comprising a memory that includes a host and an image file, a processor configured to execute the host, an input/output (I/O) controller coupled to the processor, and a management processing system coupled to the I/O controller and including a non-volatile memory is provided. The host is configured to cause the processor to provide the image file to the management processing system, and the management processing system is configured to store the image file in the non-volatile memory in response to receiving the image file from the host.

Abstract: A computer system comprising a memory including a host and an image file, a processor configured to execute the host, an input/output (I/O) controller coupled to the processor, and a management processing system coupled to the I/O controller and including a first storage location, a first memory, and a second memory is provided. The host is configured to cause the processor to store a first portion of the image file in the first memory, the host is configured to cause the processor to set the first storage location subsequent to storing the first portion in the first memory, and the management processing system is configured to store the first portion of the image file in the second memory in response to detecting that the first storage location has been set.

Abstract: A method for reducing commutation-related acoustic noise in a fan system is provided. A constant frequency periodic signal is generated and a fan commutation event is synchronized with a zero level value of the constant frequency periodic signal. A system for controlling a direct current fan is provided. The system comprises a signal generator adapted to produce a periodic signal of a constant frequency and a phase-locked loop. A zero level value of the periodic signal is synchronized with a commutation event of the fan.

Abstract: The disclosed device relates to an improved system for mounting a game playfield within a game cabinet. The device provides pivotal and sliding movement of the playfield with respect to the cabinet while allowing quick removal of the playfield entirely from the game cabinet. The game cabinet is provided with a groove on each side thereof and spring-biased pivot pins are mounted on the playfield for travel within a respective groove in the cabinet.
