Abstract: A remote indication system for a cargo door which indicates the following conditions: Opened, Closed, Latched, Unlocked and Locked. The entire system, including sensors, is independent of the standard flight deck warning system.  This provides the required redundancy for the system so that direct observation is not required. An independent system from the standard f light deck warning system and/or the indication for each step of the process rather than just "open/closed" is utilized in the present cargo door control and indicating system.

Abstract: A method of drug delivery is disclosed wherein a patient's inspiratory flow rate and inspiratory volume are simultaneously measured using a portable, hand held, device which may be electronic and battery powered or mechanical. Information obtained from the measurement is used to release into a patient's inspiratory flow path, particles of a pharmaceutically active drug. The released particles have a particle size in the range of from about 0.5 microns to 12 microns. The drug is released when the patient's measured inspiratory flow rate is in the range of from about 0.10 liters/second to about 2.0 liters/second, and the patient's inspiratory volume is in the range of from about 0.15 liters to about 0.8 liters.

Abstract: A network data distribution system which is operated, under circumstances affected by external or internal factors, without discontinuing a data distribution service while being adapted to the present situation is provided. In the server (1) side of the system, data requested from a client are divided into packets, and packet data is formed by adding a time index, and in the client (2) side, an amount of transmission or processing delay is calculated based on the time index included in the received packet data, and delay time information based on the calculated result is communicated. The server side selects the packet data to be next transmitted based on the communicated delay time information, and sends the selected packet data. That is, the client has the initiative of controlling the delay situation; thus, it is possible to perform adaptive operations according to delay situations occurring at each side of the server, the network, and the clients which are independently managed, and to realize the best data regeneration performed in the existing system capability.

IPC: H04N9/75
Filed: 1998-03-24
Granted: 2001-01-16
Abstract: This invention relates to an analog video merging system, and more particularly to a system that can take the output of a plurality of video cameras and form a combined video signal which can be fed to a computer having only a single frame grabber card. This system is used to track targets using multiple video cameras. The present invention is comprised of an analog video merging apparatus for merging N video signals from N video cameras. The apparatus is comprised of N video processors, each of the N processors is connected to the N video cameras in a one-to-one correspondence, wherein each of the N video processors compares the video signal associated with one of the N video cameras with a dynamic predetermined threshold level and produces a binaryoutput signal having a low level and a high level, the low level being output if the associated video signal is below the predetermined threshold, and high level being output if the associated video signal is above the predetermined threshold. N binary combiners are provided, with each being connected to the N video processors in a one-to-one correspondence. Each combiner produces a processed binary signal having a low level and a high level, the low level being output in the presence of a low level output from the associated video processor and a high level being output in the presence of a high level from the associated video processor, wherein the high level of said processed binary signal is a unique level to that particular binary combiner such that a unique high level is output from the N binary combiners that are associated with the N video cameras. The processed binary signal for camera N is scaled by a factor of 2N-1 with respect to the other camera signals. A summing unit is provided for summing N processed binary signals from the N binary combiners to produce a merged video signal. A method of providing a merged video signal is also provided.

Abstract: A fitting (10) for use with corrugated steel tubing (20). The fitting (10) includes a body (12) having a locating sleeve (18). The locating sleeve (18) aligns the central axis of the body (12) with the central axis of the tubing (20). Split ring washers (16) are retained on the tubing (20) by a nut (14) which is tightened on a threaded end of the body (12). As the nut (14) is tightened, a taper formed on the body (12) flares the tubing (20). The flared tubing (22) is compressed between the taper (122) on the body (12) and the beveled section (162) of the split ring washer (16). This forms a leak proof fitting without the need for separate flaring tools.

Abstract: A new, antibacterial composition for use in oral administration is now provided, which composition comprises a mixture of Cefditoren pivoxyl with a water soluble casein salt. This composition has a reduced bitter taste of Cefditoren pivoxyl and also has improved properties regarding the rate and concentration of dissolution of Cefditoren pivoxyl in water and a ratio of dissolution out of Cefditoren pivoxyl into water.        This composition further can attain a high absorbability of the Cefditoren component at the digestive tubes upon oral administration thereof. In this composition, the ratio (by weight) of Cefditoren pivoxyl to the casein salt added may preferably be in a range of 1:0.1 to 1:4.      By further addition of a water-soluble polyphosphoric acid salt to the composition, the composition can prevent a ratio of dissolution out into water of the Cefditoren pivoxyl component being decreased when the composition was stored under severe conditions.
