    摘要: To provide a pulse transmission line control system that can prevent a malfunction of microcomputers included in an apparatus configured by the microcomputers that have a function of decoding an electrical signal pulse generated from an infrared code sent from an infrared remote control unit. A main microcomputer A (1) controls on/off states of a switch (6) provided in a pulse transmission line (5) and turns on the switch (6) only when a sub-microcomputer B(2) performs a process on the infrared code sent form an infrared remote control unit (3).

    摘要: Multiple non-blocking FIFO queues are concurrently maintained using atomic compare-and-swap (CAS) operations. In accordance with the invention, each queue provides direct access to the nodes stored therein to an application or thread, so that each thread may enqueue and dequeue nodes that it may choose. The prior art merely provided access to the values stored in the node. In order to avoid anomalies, the queue is never allowed to become empty by requiring the presence of at least a dummy node in the queue. The ABA problem is solved by requiring that the next pointer of the tail node in each queue point to a “magic number” unique to the particular queue, such as the pointer to the queue head or the address of the queue head, for example. This obviates any need to maintain a separate count for each node.

    摘要: A system for automated configuration of computer peripherals. Peripherals are equipped with identification codes, which can be read by a computer, and which identify the type of peripheral. The computer stores a look-up table of configuration modes required for each peripheral type. When the computer polls a peripheral, and learns, from the identification code, that a peripheral type has changed, the computer orders a re-configuration of necessary equipment, to accommodate the change.

    摘要: The present invention provides a method in a computer system of integrating a compression system with an operating system. The computer system preferably comprises at least a memory device and one storage device. A user-supplied device driver is provided for storage devices that are not supported by the computer system to enable the computer system to communicate with the storage devices. In response to initialization of the computer system, the operating/compression system is loaded into the memory device and begins executing before any user-supplied device drivers are loaded into the memory device. Any compressed volume files located on the computer system are assigned drive letters at this time. When the user-supplied device drivers are loaded into the memory device, drive letters are assigned to the various storage devices. A drive letter conflict resolution scheme is provided to resolve conflicts that occur when the operating system attempts to assign a drive letter. The compression system assigns drive letters to compressed volume files (in the case where a compressed drive is created from free space on an existing drive) or to host drives (in the case where the contents of an existing drive are compressed).

    摘要: This invention relates to a system and method for determining the media type of a removable magnetic media, such as a floppy diskette or tape. The system performs an analysis of the media type of the removable magnetic media only after a data error is returned. If the computer does not return a data error, the system assumes that the removable magnetic media currently being read is the same media type as the previously read removable magnetic media
