摘要:
A RAID system is provided for detecting and correcting dropped writes in a storage system. Data and a checksum are written to a storage device, such as a RAID array. The state of the data is classified as being in a “new data, unconfirmed” state. The state of written data is periodically checked, such as with a timer. If the data is in the “new data, unconfirmed” state, it is checked for a dropped write. If a dropped write has occurred, the state of the data is changed to a “single dropped write confirmed” state and the dropped write error is preferably corrected. If no dropped write is detected, the state is changed to a “confirmed good” state. If the data was updated through a read-modified-write prior to being checked for a dropped write event, its state is changed to an “unquantifiable” state.

A method and system for personalizing a plurality of parts are disclosed. All of these parts have an identical part number and one or more programmable functions. The method comprises the steps of employing in a first product a first of said parts; and employing in a second product, a second of said parts. Prior to normal operation of the first product, a first code is set in the first part, and this first code causes the first part to provide a first programmable function during normal operation of the first product. Prior to normal operation of the second product, a second code is set in the second part, and this second code causes the second part to provide a second programmable function during normal operation of the second product. The said second programmable function is different from the first programmable function.

An inhalation device in the nature of a metered dose inhaler with a counter is disclosed. The device is designed to work with existing respiratory drugs. The device is comprised of a L-shaped medication dispenser in which a counter is attached. A downward force applied to the top portion of the canister protruding from the top of the L-shaped medication dispenser releases a single dose of the aerosol medication and increments the counter. The device contains a visual display of the current count and thus an indication of the metered doses remaining in the aerosol canister. The counter can be electronic, mechanical or electro-mechanical in nature. Counting devices for other shaped dispensers such as cylindrical dispensers are also described. Other options such as a warning alarm, automatic power conservation shutdown of the display, and full computer monitoring functions are also disclosed.
