  • Patent number: 5077736
    Abstract: The disk drive memory of the present invention uses a large plurality of small form factor disk drives to implement an inexpensive, high performance, high reliability disk drive memory that emulates the format and capability of large form factor disk drives. The plurality of disk drives are switchably interconnectable to form redundancy groups of N+M parallel connnected disk drives to store data thereon. The N+M disk drives are used to store the N segments of each data word plus M redundancy segments. In addition, a pool of R backup disk drives is maintained to automatically substitute a replacement disk drive for a disk drive in a redundancy group that fails during operation. The number N of data segments in each data redundancy group can be varied throughout the disk drive memory to thereby match the characteristics of the input data or operational parameters within the disk drive memory.

  • Patent number: 4989205
    Abstract: The disk drive memory of the present invention uses a large plurality of small form factor disk drives to implement an inexpensive, high performance, high reliability disk drive memory that emulates the format and capability of large form factor disk drives. The plurality of disk drives are switchably interconnectable to form parity groups of N+1 parallel connected disk drives to store data thereon. The N+1 disk drives are used to store the N segments of each data word plus a parity segment. In addition, a pool of backup disk drives is maintained to automatically substitute a replacement disk drive for a disk drive in a parity group that fails during operation.

  • Patent number: 4969276
    Abstract: An air filter and humidifier is attached to the back of a clothes dryer. Exhaust air is ducted from the clothes dryer exhaust port to the inlet port on the bottom of the filter/humidifier. From there, the exhaust air is directed upwardly through the filter/humidifier. A deflector redirects the exhaust air obliquely downward against the surface of water within a container. The water humidifies and filters the exhaust air. A variable amount of the conditioned air escapes through an adjustable vent lid into the home and the remainder is discharged through the filter/humidifier and ducted outdoors. A hinged or removable lid allows the user to remove the water container to add or replace water.
