Title: Gray level addressing for lcds
Inventor: SCHEFFER TERRY J
IPC: G09G3/20
Filed: 1993-05-11
Abstract: GRAY LEVEL ADDRESSING FOR LCDS                     ABSTRACT OF THE DISCLOSURE             Method and apparatus for providing gray level addressing for passive liquid crystal display (LCD) panels having overlapping row and column electrodes defining pixels are disclosed. Depending upon whether the rows are being addressed by "standard" or "Swift" addressing, the signals for applying to the column electrodes are determined by different calculations, in all of which modes the amplitudes of the column signals are related to the gray level desired to be displayed by the individual pixels. For a split interval system, column signals of appropriate amplitude and polarity are applied during different subintervals of a characteristic time interval of the display panel depending upon the method of addressing the rows. In the full interval mode, the column signals applied over a full time interval are based on the desired gray level of all the pixels in the column, adjusted to provide the proper rms voltage across all the pixels so that they display the desired gray levels.

Title: Soil/medium/polar fluid impedance controller
Inventor: MAYHEW KENT W
IPC: G05D22/02
Filed: 1993-08-16
Abstract: Abstract The impedance of a soil/medium is inversely proportional to percentage of polar fluid in the soil/medium.  There are many soil/medium moisture control devices that utilize the relation of soil/medium moisture and it's impedance but they generally are complicated devices both from an electronics and a user point of view. This invention uses a fluid detector circuit (based on a National Semiconductor, LM1830 microchip), impedances and a quad bilateral switch circuit to create a voltage divider circuit. This invention allows one to maintain the soil/medium impedance within a specified range (which corresponds to a range in moisture content for the soil/medium).  This invention uses an ac signal,  thus problems associated with plating of the probes are minimized.

Patent CA-2114869-A1 (CA)
Inventor: FILAS ROBERT W
IPC: C23C18/28
Filed: 1994-02-03
Abstract: An electroless process has been developed to deposit nickel and gold onto optical fibers using aqueous chemistry. The key to the process is a sensitization of a surface of an optical fiber using a dilute aqueous stannous fluoride solution in absence of oxygen. Stannous fluoride solution is prepared by dissolving crystalline SnF2 in deionized water. Subsequent treatment includes immersion of sensitized optical fiber in a palladium chloride/HCI aqueous solution and commercially available electroless nickel and electroless gold solutions. The process is compatible with either chemical or fusion lensing operations by using a strippable polymer coating to selectively metallize near the fiber end. The solder joints to the metallized fiber are hermetic as determined by helium leak testing and solder pull-test strengths typically range from 3-5 pounds, depending on the type of solder. This electroless plating process for metallizing optical fibers makes feasible the incorporation of soldered fiber into packages which might be otherwise prohibitively expensive ormechanically infeasible with the sputtered metallization. The process is useful for all lightwave components which require either hermeticity or high reliability optical fiber attachment.

Title: Information broadcasting system and method
Inventor: LEVINSON FRANK H
IPC: H04N7/173
Filed: 1992-10-27
Abstract: An information broadcasting system (100) provides a large number of subscribers access to a large amount of information using one or more satellite transmission channels. The system (100) can also use cable television transmission channels. A program supplier station (102) stores an information database (112) and tags all the information in the database with indices so as to form a single hierarchical structure which encompasses the entire information database (112). Portions of the information database (112) are transmitted often, at least once per day, in order to provide the basic subscriber with information need to access the remainder of the database (112). The information provided by the basic subscriber service, which will typically include at least 50 gigabytes of data, is available to all subscribers without requiring two way communications between the subscribers and the program supplier station. Using a tiered system for scheduling transmission of the 50 gigabytes or so of information included in the basic subscriber service, as well as an intelligent subscriber request anticipation scheme for retrieving information before the subscriber asks for it, the present invention provides subscribers with reasonably quick access to all the contents of the large database while using only a modest amount of bandwidth.

Title: End-Fitting for Pipe Connection
Inventor: PETERSEN HORST U
IPC: F16L37/088
Filed: 1994-06-27
Abstract: For use in push-in-and-snap pipe connectors, the region of the pipe behind the integral end-flange is raised in diameter. If the pipe is properly inserted, the raised region is concealed inside the body of the fitting; but if the pipe is not pushed fully home into the body, the raised region is visible, and serves to alert the production-line inspector that the joint is not sealed. A snap-in sping clip holds the pipe in the body, and the clip rests against the raised protion to minimise the chance of vibration noise. The flange and raised region are formed in the pipe by axial-press punches and dies.
