Patent number: 10708546Abstract: A portable magnifier camera with an associated display housing, base and handle. The camera can be selectively positioned into a variety of configurations, including: a first closed configuration wherein the display and base are in facing relation; a second opened configuration wherein the display is angled with respect to the base; and a third hand-held configuration wherein a handle is pivoted outwardly to permit a user to hold the camera relative to a distant object. The angle of the camera adjusts automatically in each configuration to ensure that the camera's light of slight is perpendicular to the object plane. These configurations enable a user to effectively view objects of differing size and at varying distances.Type: GrantFiled: June 4, 2018Date of Patent: July 7, 2020Assignee: Freedom Scientific, Inc.Inventors: Carlos M. Rodriguez, Patrick Murphy, Waldemar H. Tunkis, Todd Conrad, Michael Goldenberg, Lee Hamilton, Bradley S. Davis, Robert Leon
