  • Publication number: 20190185865
    Abstract: The present invention relates to the use of transcriptional activators from prokaryotic organisms for use in eukaryotic cells, such as yeast as sensors of intracellular and extracellular accumulation of a ligand or metabolite specifically activating this transcriptional activator in a eukaryot, such as yeast cell, such as a cell engineered to produce this ligand. The transcriptional activator controls a promoter upstream of one or more gene, which may include e.g. a reporter gene that may be a fluorescence marker, such as luciferase, green fluorescent protein or a gnee encoding antibiotic resistance.

  • Patent number: 9283567
    Abstract: A shredder has a jam proof system with a thickness detector having a contact member which displaces as an article is inserted into the shredder and a resistance generating mechanism which provides a resistance force to the contact member, in response to its displacement. The greater the thickness of the article, the greater the resistance force realized. When a predetermined thickness is reached, there is a significant change in the resistance force. The resistance generating mechanism may include at least two spring mechanisms and provide feedback to the user that the inserted article may be too thick. In addition, the thickness detector may include a thickness sensor. The sensor may communicate with a controller to alert the user, and/or alter the operation of the shredder, in response to the thickness of the inserted article. For example, the controller may visually and/or audibly alert the user, or control shredder motor response.

  • Patent number: 8925841
    Abstract: An electrical appliance, such as a shredder, having low standby power consumption is provided. A power isolation circuit is positioned to electrically disconnect electronic components of the shredder from the shredder's primary power source. An auxiliary power source may generate or store power for powering electronic components, such as sensors or processors, while the primary power source is disconnected. A power isolation controller may use a timer, light detector, or user interaction sensors to determine whether to reconnect the primary power source to the electronic components.
