  • Publication number: 20170138006
    Abstract: An example retractable bollard system for installation in a support surface that includes pavement is disclosed. The example bollard system includes a shell that when installed in the support surface extends below an upper surface of the pavement. The example bollard system includes a post to be telescopically coupled to the shell. The post is axially movable relative to the shell selectively to an upper area and a lower area. The post extends farther above the shell when the post is in the upper area than when the post is in the lower area. The example bollard system further includes a shock absorber to encircle the shell. The shock absorber is made of a polymeric material.

  • Patent number: 9309717
    Abstract: Powered safety curtains are disclosed herein. An example safety barrier assembly to control access to equipment includes a track and a barrier including a receptacle. The barrier is to be moveable within the track between an open position and a closed position. The open position is to enable access to the equipment, the closed position to substantially prevent access to the equipment. The example safety barrier assembly also includes a sensor to identify when the safety barrier is in the closed position and a securing device comprising a portion to be received by the receptacle when the barrier is identified as being in the closed position. An interaction between the portion and the receptacle is to prevent the barrier from moving out of the closed position.

  • Publication number: 20150257496
    Abstract: An article of jewelry with interchangeable settings and decorative elements is provided. Each interchangeable setting includes a post having a post shoulder and a pair of tabs. The post is removable received and retained by a socket of the article of jewelry by inserting the post into the socket and rotating the setting to position the tabs in a retained position within a pair of corresponding grooves formed in the socket. An end of the socket abuts the post shoulder and prevents the interchangeable setting from side-to-side movement. Decorative elements are rotatably retained by the post between the setting and the socket.

  • Publication number: 20070195408
    Abstract: The invention has two main embodiments, a first called column switching and blanking and a second embodiment called doubling. The first embodiment is a projector for displaying a stereoscopic image with projector using one or more digital micromirror devices positioned into a plurality of columns and rows. The projector itself includes a light source, an optical system, a video processing system and a data system for driving the micromirror devices. The data subsystem provides separate data to a plurality of column pairs of the micromirrors. The projector includes a stereoscopic control circuit having a first state of the control circuit for inputting a first eye view of the stereoscopic image and causing the micromirrors of a first column of each column pair to be in various on and off states during said first eye view of said stereoscopic image and for causing all of said micromirrors of a second column of each column pair to be in an off state during said first eye view of said stereoscopic image.

  • Patent number: 7180554
    Abstract: A digital micro-mirror device (DMD) format conversion system for outputting a stereoscopic encoded optical signal using a DMD and a color wheel is provided. The DMD format conversion system includes a 3D data formatter for receiving an input signal and a DMD data formatter for receiving an output signal having stereoscopic image information and control information from the 3D data formatter and for outputting a DMD output signal having stereoscopic image information and control information. A color wheel control signal and output digital micro-mirror device data are synchronized based on an output frame rate generated by the 3D data formatter independent of the original input frame rate.

  • Publication number: 20070024870
    Abstract: The present invention provides apparatuses and methods for determining spatial information of a workpiece surface positioned in a predetermined coordinate system. Apparatuses and methods of the present invention can be used to determine one or more coordinates of one or more measurement locations of a workpiece within a predetermined coordinate system. Such coordinates can be used to define points, lines, and/or surfaces of the workpiece within the coordinate system. In one exemplary application, apparatuses and methods of the present invention can be used to determine spatial information of surfaces of head suspensions or head suspension assemblies such as those that are generally utilized in dynamic storage devices such as magnetic disk drives. Such spatial information can be used to determine z-height and/or static attitude, for example.

  • Publication number: 20050247958
    Abstract: The invention is a method for creating a micropolarizer, including providing a first plate having a first and a second surface, providing a second plate having a first and a second surface. Then coating a polyimide on each of the first surface of the two plates followed by rubbing the polyimide coated upon the first surface of the first plate along a predetermined direction and rubbing the polyimide coated upon the first surface of the second plate along a direction having a predetermined angle in relation to the predetermined direction. An alignment process includes aligning the first plate and the second plate having the first surface of the first plate and the first surface of the second plate facing each other thereby creating a space there between. In conclusion there is a filling of a liquid crystal material in the space whereby a cell, or film is created.

  • Publication number: 20050139163
    Abstract: A bird feeder wherein a housing includes a plurality of modular hopper elements with a floor underlying and supporting the hopper elements and a roof overlying the hopper elements, the hopper elements including impermeable side walls juxtaposed to form a hopper assembly of maximum capacity and minimum footprint and a front wall with feed apertures to enable birds to access bird food within the hopper element. Each hopper may be selectively removed and replaced without disturbing the other elements. In one embodiment, the hopper elements form segments of an inverted frustoconical hopper assembly which may be selectively and individually removed from the bird feeder without disassembling the housing.

  • Publication number: 20050078108
    Abstract: The preferred embodiment addresses the problem of delivering stereoscopic media in electronic form (images, videos, animations, object models, etc.). First, it provides a single format with independent right and left channels to represent the stereoscopic media. Second, it provides a means of displaying stereoscopic media inside a movable windowed area while eliminating pseudostereo conditions during movement. Third, it provides automatic and manual optimization adjustments (parallax shift adjustment, brightness control, color adjustment, and cross-talk reduction) to the stereoscopic media based on viewing hardware, monitor size, and media content for optimal viewing quality. Fourth, it provides seamless support for monoscopic (2D) viewing modes allowing delivery of said stereoscopic media in a normal 2D viewing mode.
