  • Publication number: 20180055208
    Abstract: An oral care implement that includes a handle and a head. A tuft of cleaning elements extends from the front surface of the head along an axis and includes a plurality of cleaning elements. In one embodiment, the cleaning elements may be formed of an elastomeric material. Furthermore, a sleeve may be coupled to the head and extend from the front surface of the head. The sleeve circumferentially surrounds a first portion of the tuft of cleaning elements and a second portion of the tuft of cleaning elements protrudes beyond a distal end of the sleeve. The sleeve may apply a radial compression force onto the first portions of the cleaning elements that are surrounded by the sleeves. The second portions of the cleaning elements may diverge as they extend from the distal end of the sleeve. The oral care implement may include sleeves of varying heights.

  • Publication number: 20170201744
    Abstract: For aligning an image sensor relative to a lens module prior to fixing the image sensor to the lens module, an exposure of the image sensor is turned on and the image sensor is moved to different distances relative to the lens module. At certain predetermined distances between the image sensor and the lens module, a calibration pattern is illuminated and two or more pictures of the calibration pattern which is focused through the lens module are captured with the image sensor to produce at least two pictures of the calibration pattern captured at different distances, the at least two pictures being superimposed onto a calibration image. The exposure of the image sensor is then turned off and the pictures of the calibration pattern are analyzed for determining an alignment between the lens module and the image sensor.

  • Patent number: 9557002
    Abstract: A convertible stand/table may be converted for use alternately as a table or a stand, and in particular, a stand suitable for use in mounting, securing, holding, or otherwise retaining or mounting one or more items for viewing and/or use by an individual, including, for example, a tablet or other portable computing device. Further, in some configurations, a magnetic mounting pad, including a suction cup surface and at least one permanent magnet, may be used to mount a portable electronic device such as a tablet on an inclined and magnetically-attractive surface, with the suction cup surface, e.g., provided by a microsuction layer, adhered to the back of the portable electronic device, and with the permanent magnet attracted to the magnetically-attractive surface.

  • Patent number: 9519152
    Abstract: There is provided an apparatus for alignment of a thin-film transistor (TFT) panel and a barrier panel of a three-dimensional (3D) display. The apparatus comprises at least one light source for illuminating pixels in at least one region of the TFT panel and for illuminating at least one region of an exposure pattern of the barrier panel; a pattern recognition system for detecting light emitted from the at least one light source that is reflected by or transmitted through the 3D display, to generate alignment data relating to an alignment between the detected illuminated pixels of the TFT panel and the exposure pattern of the barrier panel; and a positioning mechanism for adjusting the relative position between the barrier panel and the TFT panel in relation to the alignment data. The at least one light source comprises at least one invisible light source which emits invisible light outside the visible region of the electromagnetic spectrum.

  • Patent number: 9103150
    Abstract: A locking hinge design relies on a mechanically-actuated magnetic clutch to selectively disengage first and second gears respectively coupled to first and second members and thereby selectively enable relative rotation between the first and second members about an axis of rotation. The mechanically-actuated magnetic clutch includes first and second magnetic members disposed in an opposing relationship, such that permanent magnets respectively disposed in each magnetic member may be placed into either a mutually attractive or mutually repellant relationship in response to relative movement therebetween. One of the magnetic members is coupled to one of the gears to move the gear along the axis of rotation and thereby selectively disengage or engage the gear from or with the other gear such that the gears are selectively engaged in response to mechanical movement of the magnetic members.
