Patents by Inventor Edward C. Fisher

Edward C. Fisher has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10635653
    Abstract: A method includes retrieving, by a processor, a first entry from a global wait list as a current waiting lock. The method further includes decreasing, by the processor, a deadlock timer of the current waiting lock. The method further includes determining, by the processor, whether the deadlock timer equals zero. The method further includes appending, by the processor, the current waiting lock to an end of a deadlock victim selection list, if the deadlock timer equals zero. The method further includes selecting, by the processor, a victim from the deadlock victim selection list.
    Type: Grant

  • Patent number: 7473578
    Abstract: A packaged micromechanical device (100) having a blocking material (116) encapsulating debris-generating regions thereof. The blocking material (116) prevents the generation of debris that could interfere with the operation of the micromechanical device (100). Debris-generating regions of the device (100), including debris-creating sidewalls and any debris-harboring cavities, as well as electrical connections (108) linking the device (100) to the package substrate (102) are encapsulated by the blocking material (116). The blocking material (116) avoids contact with any debris-intolerant regions (118) of the device (100). A package lid (122), which is glass in the case of many DMD packages, seals the device (100) in package cavity (120).

  • Patent number: 6806993
    Abstract: The present invention provides, in one aspect, a method of manufacturing a MEMS assembly. In one embodiment, the method includes mounting a MEMS device, such as a MEMS mirror array, on an assembly substrate. The method further includes coupling an assembly lid to the assembly substrate and over the MEMS device to create an interior of the MEMS assembly housing the MEMS device, whereby the coupling maintains an opening to the interior of the MEMS assembly. Furthermore, the method includes lubricating/passivating the MEMS device through the opening. In addition, a MEMS assembly constructed according to a process of the present invention is also disclosed.

  • Patent number: 5936758
    Abstract: A method of passivating a hermetically sealed micromechanical device (14) with a passivant (100). A predetermined quantity of the passivant (100) is placed within the cavity (54) of a lid (42) after the lid and package base (46) have been activated. Thereafter, by heating the package (10) including the passivant, the passivant will sublime within the hermetically sealed package (10) to provide a monolayer of passivant across the active surfaces of the micromechanical die (14). An improved hermetic seal is achieved since the passivant is sublimed after the laser weld process. In addition, the effectiveness of the passivation process is improved since the passivation is performed after the package is sealed, without the risk of any impurities entering into the package to degrade the effectiveness of the passivation.
