  • Patent number: 9810887
    Abstract: A quadric reflector can have an approximately conical shape. The shape can tapers from a wide base to an apex. The apex can include an aperture, a mirror, and a set of one or more optical elements. A mirror can be positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror can reflect environmental light that is reflected by the quadric reflector into the aperture or reflect light emitting from the aperture onto the quadric reflector. The overhang enclosure can have a substantially conical shape which eliminates secondary reflection resulting from the environmental light reaching the aperture twice. Using the overhang enclosure to absorb the secondary reflection eliminates or minimizes banding.

  • Patent number: 9024085
    Abstract: The present invention is directed to processes for recovering ethanol obtained from the hydrogenation of acetic acid. Acetic acid is hydrogenated in the presence of a catalyst in a hydrogenation reactor to form a crude ethanol product. The crude ethanol product is separated in one or more columns to recover ethanol. In some embodiments, less than 10 wt. % ethanol is recycled to the hydrogenation reactor.

  • Patent number: 9018426
    Abstract: In one embodiment, the invention is to a process for producing multi-carbon alcohols, including butanol and/or hexanol. The process comprises the step of reacting ethanol in a reactor to form a crude product comprising butanol, ethanol, and water. The process further comprises the step of separating at least a portion of the crude product in a first distillation zone to form a first distillate comprising ethanol and a first residue comprising butanol, and water. The process further comprises the step of separating at least a portion of the first residue in a second distillation zone to form a second distillate and a second residue comprising butanol.

  • Patent number: 8645187
    Abstract: An embodiment of the invention is directed to retaining customers for a wireless-service provider (“carrier”). A ratio is calculated based on a number of incoming calls received by a mobile device and a number of outgoing calls originating from the mobile device. The ratio is also based on locations of callers that originated the incoming calls. The ratio is compared to an influencer threshold. When the ratio is greater than the influencer threshold, then a subscriber associated with the mobile device is indicated to be an influencer that potentially affects decisions of other subscribers regarding whether to cancel or maintain their subscriptions with the wireless service. An incentive is provided to the influencer to increase the likelihood that the influencer will retain a subscription with the wireless service, thereby increasing the likelihood that other subscribers who might be influenced by the influencer will retain their respective subscriptions.

  • Patent number: 8214253
    Abstract: An embodiment of the current invention is directed to retaining customers for a wireless-service provider (“carrier”). A plurality of users who are influencers are identified from a group of wireless-service subscribers, wherein an influencer is a user who is likely to affect decisions of other users regarding whether to cancel or maintain their subscriptions with a particular carrier based on whether the influencer cancels or maintains his or her subscription. A list of influencers is thereby created. An incentive to provide the list of identified influencers is determined. The incentive increases the likelihood that the set of influencers will retain their respective subscriptions, thereby increasing the likelihood that other subscribers who might be influenced will also retain their respective subscriptions.
