摘要:
A two-piece assembly with an internal attachment mechanism includes a tray providing a tray channel and a lid providing a lid channel. The lid is mateable to the tray such that their respective channels combine to form a duct. A bonding material is received in the duct such that the tray and the lid are bonded to one another.

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

A method of displaying a status condition of a smart battery being charged by a smart battery charger. The method includes: transmitting data from the smart battery to a computer, wherein the smart battery charger is external to the computer; processing said data in accordance with a software program being executed by a central processing unit within the computer; and displaying information obtained as a result of processing said data on a display screen coupled to the computer.
摘要:
The present invention uses multithreaded interrupt processing to permit simultaneous activation of multiple disk drives in a computer system. A data transfer request from an application software program includes a disk data transfer command identifying the disk drive designated to receive the command and an identification data element indicating the application software process associated with the disk data transfer command. A device driver processing multiple disk transfer commands analyzes the data transfer command and identification data element to identify independent disk data transfer requests. If no independent data transfer requests are identified, the device drive sequentially processes disk data transfer commands. However, if the device driver identifies independent disk data transfer commands, the device driver can process commands out of sequence so that the two independent disk data transfer commands may be simultaneously processed. In this manner, multiple disk drives can be active simultaneously.
摘要:
A system for multi-threaded disk drive interrupt processing uses a flag register containing encoded data bits to indicate the current status of at least two disk drives. Instructions in a basic input-output system (BIOS) causes a central processing unit (CPU) to execute instructions to transfer data to the two disk drives. The system permits both disk drives to be simultaneously active. The system can issue commands to a first disk drive and, while the first disk drive is responding to those commands, issue additional commands to a second disk drive to prepare for additional data transfers. When one of the two disk drives generates an interrupt, the system can determine which disk drive generated the interrupt and process the interrupt. If the operating system is a multi-threaded operating system, the present invention interrupts the ongoing thread to process the interrupt. The present invention then returns control to CPU to the ongoing thread so that it may complete the ongoing thread before transferring data to or from the disk drive that generated the interrupt. The system may apportion a data file into segments that are stored alternately on the first disk drive and the second disk drive. Overall data transfer efficiency is improved by having the second disk drive responding to commands while the first disk drive is transferring data. During a subsequent transfer of a portion of a data file to the second disk drive, the first disk drive may be responding to commands for the transfer of additional portions of the data file. Thus, the system alternately transfers portions of data to or from the first and second disk drives.

This invention relates to methods and reagents for inhibiting furin endoprotease activity and specifically for inhibiting furin endoprotease-mediated maturation of bioactive proteins in vivo and in vitro. The invention specifically provides proteins capable of inhibiting furin endoprotease activity. Particularly provided are .alpha..sub.1 -antitrypsin variants that specifically inhibit furin endoprotease activity. Methods for using furin endoprotease inhibition to attenuate or prevent viral protein maturation, and thereby alleviate viral infections, are provided. Also provided are methods for using furin endoprotease inhibition to attenuate or prevent proteolytic processing of bacterial toxins, thereby alleviating bacterial infections. Methods are also provided to inhibit proteolytic processing of biologically active proteins and peptides. The invention also provides pharmaceutically acceptable compositions of therapeutically effective amounts of furin endoprotease inhibitors.
摘要:
An ice protection system for a vehicle is disclosed which includes a plurality of de-ice power distribution units positioned proximate to a leading edge surface of the vehicle that is susceptible to ice accretion, at least two anti-ice power distribution units located within the vehicle, spaced from the de-ice power distribution units, and a point of power regulation located within the vehicle, spaced from the power distribution units, from which power is fed to the power distribution units through independent feeder wire bundles so as to distribute line current across the system in a manner that optimizes wire weight.

A virtual mass storage device implements a data manager for storing information on multiple physical mass storage devices. The virtual mass storage device is organized into blocks of information, which are allocated to different physical devices, thereby enabling the physical devices to operate in parallel and increase the overall transfer rate of the virtual device.

摘要:
A method and system for notifying a viewer of the arrival or presence of one or more video input signals in a video display system, such as a personal computer (PC) or television (TV) system. If a video signal is already present, the system may optionally notify a viewer of the termination or absence of the video signal. The invention further provides the viewer with the opportunity to dynamically select the video source to view. Upon sensing the presence of a new video signal, the system alerts the viewer who may then select whether to view the new video signal or maintain prior viewing status.
