  • Publication number: 20240105683
    Abstract: Structures including multiple semiconductor devices and methods of forming same. The structure comprises a first device structure including a first well and a second well in a semiconductor substrate, a second device structure including a doped region in the semiconductor substrate, and a first high-resistivity region in the semiconductor substrate. The first well has a first conductivity type, the second well has a second conductivity type opposite to the first conductivity type, and the first well adjoins the second well to define a p-n junction. The doped region of the second device structure has the first conductivity type or the second conductivity type. The high-resistivity region has a higher electrical resistivity than the semiconductor substrate, and the high-resistivity region is positioned between the first device structure and the second device structure.

  • Patent number: 10832035
    Abstract: Disclosed techniques relate to identifying subjects in digital images. In various embodiments, digital image(s) that depict a subject in an area may be acquired. Portion(s) of the digital image(s) that depict a face of the subject may be detected as detected face image(s). Features of each of the detected face image(s) may be compared with features of each of a set of subject reference templates associated with a given subject in a subject reference database. Based on the comparing, a subject reference template may be selected from the set of subject reference templates associated with the given subject. Similarity measure(s) may then be determined between a given detected face image of the detected face image(s) and the selected subject reference template. An identity of the subject may be determined based on the similarity measure(s).

  • Patent number: 8067432
    Abstract: A method for preparing a stable dispersion of a camptothecin, camptothecin prodrug, or analog thereof for administration to a patient in need thereof includes preparing a solution of the camptothecin, wherein the solution has a pH which places substantially an entirety of that camptothecin in a carboxylate form. The camptothecin may be a neutral camptothecin. The solution is next loaded into a liposome including at least one lipid, which may be a phospholipid. An intraliposomal pH is maintained which preserves substantially an entirety of the camptothecin in the carboxylate form. The liposomal dispersion is administered to an individual in need thereof, whereby the liposomes accumulate at and permeate into tumor tissue and an active, lactone form camptothecin is released in situ at the tumor site. Compositions formulated in accordance with the described method for treatment of a cancer in an animal in need thereof are provided also.

  • Patent number: 7197903
    Abstract: A method and apparatus for providing a storm door with a mortise lock that includes a lock body having opposed side plates and a cam in between the side plates, the cam being in operative interaction with a dead bolt assembly. The mortise lock body also includes one or more stops to limit the rotation of the cam and prevent a lockout situation. A thumb turn button and key cylinder are secured to opposite escutcheon plates. A spindle traverses from the key cylinder through the cam through hole and terminates in the mounting slot of the thumb turn button. Rotation of either the thumb turn button or the key cylinder turns the spindle and actuates the cam that actuates the dead bolt assembly.

  • Patent number: 7152442
    Abstract: A method for installing a storm door with a mortise lock that includes a lock body having opposed side plates with a dead bolt assembly and a live bolt assembly intermediate the side plates wherein a key cylinder is separate from the cam. A thumb turn button and key cylinder are secured to opposite escutcheon plates and the cam is separately secured between the side plates of the mortise lock body. The key cylinder includes one or more key pins in the key cylinder housing and preferably in the decorative portion thereof. A spindle traverses from the key cylinder through the cam through hole and terminates in the mounting slot of the thumb turn button.

  • Patent number: 6653319
    Abstract: The present invention provides a general method to retard the precipitation inception time for poorly water-soluble camptothecin analogues from a supersaturated solution by a chemical conversion approach via pH alteration. This method is successfully utilized to prepare stable parenteral formulations for silatecan 7-t-butyldimethylsilyl-10-hydroxycamptothecin (DB-67), a poorly water-soluble lipophilic camptothecin analogue, in aqueous solutions containing &bgr;-cyclodextrin sulfobutyl ether (SBE-CD) or other solubilizing agents. The formulations manufactured by this method are more simple and cost-effective, of higher doses and better quality in terms of manufacture loss and formulation stability, and can be free of organic solvents (e.g., DMSO or N-methyl-2-pyrrolidinone).
