    摘要: A prism for color dispersion and recombination and a projector incorporating the prism. The prism comprises an aperture for a light beam and the normal to the aperture defines an optic axis. A first surface, intersecting the optic axis, is oriented at a first angle to the optic axis. The first angle is greater than 45.degree.. The first surface disperses the light beam into a first component and an intermediate component. A second surface, intersecting the optic axis, is oriented at a second angle to the optic axis. The second surface disperses the intermediate component of the light beam into a second component and a third component.

    摘要: A baby bottle holder provides for the hands free holding of a baby bottle for bottle feeding an infant, thus enabling the person caring for the infant to have both hands free for holding the infant and/or performing other duties as required. The holder comprises several embodiments, each of which has a neck sling removably securable about the neck of the user and a bottle securing strap which secures removably about the neck of the baby bottle adjacent the nipple end of the bottle. Some embodiments comprise a pliable sleeve having a conical section with all diameters greater than that of the bottle, with the bottle being placed in the sleeve with the nipple end toward the larger diameter portion of the sleeve. The nipple of the bottle thus extends downwardly for feeding the infant, with the bottle being secured by the bottle securing strap. The bottle is easily tilted upwardly to preclude leakage from the nipple when not in use, by everting the sleeve over the upper end of the bottle. Other embodiments utilize an elastic strap for the sleeve portion, with a pliable connecting sheet or strap between the sleeve and the bottle securing strap. The bottle may be positioned with the nipple upward by sliding the elastic sleeve toward the nipple end of the bottle, thus positioning the center of gravity of the bottle beyond the sleeve. Each embodiment allows the user to position the bottle easily either nipple downward or nipple upward, as desired.

    摘要: An image projection arrangement is provided. The arrangement includes a light source assembly for producing a first light beam. A reflective image display system is arranged in the path of the first light beam and has at least one cell for generating an image to be projected. A projection lens system is arranged in the path of a second light beam originating from the image display system for projecting the image produced by the image display system onto a projection screen. Between the light source assembly and the image display system on the one hand, and between this system and the projection lens system on the other hand, a transition from a first to a second medium is provided. This transition occurs at an interface having a normal direction. The first and second media have different refractive indices. The transition is arranged such that one of the first and second light beams is totally reflected by the transition while the other light beam is transmitted by the transition. Between the light source assembly and the image display system on the one hand, and between this system and the projection lens system on the other hand, an angle is formed, the bisector of this angle defining an optic axis of the system. The bisector of the angle is not parallel to the interface normal.

    摘要: A color projection display uses a dichroic cube for modulating the color of light reaching the imaging element of the display. This way, a colored image may be projected by frame sequential technique, but with the use of only a single imaging element.
