  • Patent number: 9805018
    Abstract: A natural language processing methodology to automatically transform push advertising into pull advertising. Text found in forum, blog, and social media postings throughout the Internet is grammatically analyzed to identify potential customers who have expressed a clear problem. Only parsing rules with the least likely elements present are evaluated. In response, personalized replies are produced that contain pertinent and useful information about a potential product or service. Those replies appear to come from other Internet users, thus converting expressed needs of user/prospects into discussions with sales technicians.

  • Patent number: 9229213
    Abstract: A microscope having an objective lens and illumination means configured in combination such that said illumination means illuminates a specimen through a different region of the objective lens than that used for observation, and having an opaque region separating the illumination and observation regions. The basic optical design is capable of resolving optically isolated micron-sized voxels deep within tissue, without the use of a computer and when illuminated only with visible light.

  • Patent number: 4274684
    Abstract: The bearing is configured to retain oil by capillary action. In one embodiment, a lubricant recess is provided at each end of the bearing, which recess may be completely open to the atmosphere, provided that there is an abrupt edge joining the recess to the end of the bearing, and further provided that the recess is large enough (1) to accommodate the lubricant in the bearing and (2) to permit skewing of the bearing shaft without resulting contact between the bearing shaft and the wall of the recess. An additional recess, referred to as a pressure distribution groove, may also be provided in the bearing inward of the end recess. Alternatively, a reservoir groove capable of accommodating the bearing lubricant may be provided at each end of a bearing having no open recess, which reservoir groove is separated from the bearing end by a narrow baffle. A pressure distribution groove may also be provided in combination with the reservoir groove.
