  • Patent number: 6785046
    Abstract: A viewing device (10) adapted to be held at eye level by an apparatus (14) comprises a housing (16) designed to fit within a tray (12) of the apparatus (14), two eyepieces (22) mounted to a proximal end (24) of the housing, a magnification mechanism (26), and a focus mechanism (28). The device (10) also includes an objective lens (18) and a video screen (19) mounted to a distal end (20) of the housing (16). The housing (16) preferably includes a substantially flat bottom (30) and two substantially flat sides (32) and is preferably secured to the tray (12) by a threaded fastener (36). The eyepieces (22) are preferably flexible and padded to provide a comfortable fit. The eyepieces (22) may be either contoured or substantially flat. The contoured eyepieces (22) fit against a user's face. The substantially flat eyepieces (22) fit against the user's eyeglasses.

  • Patent number: 6392798
    Abstract: An apparatus (10) for conveniently holding a viewing device (20) at the eye level of the user is provided, which allows the user to properly position the device (20) for ease of use without the need for continually holding the device (20), and also allows the device (20) to be pivoted to a retracted, non-use position. The apparatus (10) includes an attachment headband (16) which pivotally supports a pair of elongated, forwardly extending arms (12, 14); a tray (18) extends between and is secured to the arms (12, 14) and supports the device (20). The tray (18) is adjustable both vertically and in a fore and aft direction so that it can be precisely positioned for each individual user. A cap assembly (92) may be releasably secured to the apparatus (10) to cover the user's head and the device (20).

  • Patent number: 5553627
    Abstract: An improved tongue depressor (10) that has a flat elongated blade (12) having a first end (14) and a second end (16). To the first end (14) is integrally attached a first tongue-contact section (34) and to the second end (16) is integrally attached a second tongue-contact section (70). Each of the tongue-contact sections has a lower surface (42) that includes sequentially, a downward slope (44), (80), a flat horizontal surface (48), (84) and an upper slope (52,88). The downward slope and the flat horizontal surface interface with the tongue and preferably have a non-slip surface (60). At the center and lower horizontal surface (20) of the elongated blade (12) is located a reinforcing protrusion (28) that prevents the tongue depressor from bending or breaking in the middle. Because the size of an adult mouth is generally larger than a child's mouth, one of the tongue-contact sections is made with a smaller width. Also, the tongue depressor is constructed of a plastic.
