  • Publication number: 20130135181
    Abstract: In a device or a method for determining the direction of vision of an eye, a starting point or a final point of a light beam reflected by a part of the eye and detected by a detector system, or of a light beam projected by a projection system onto or into the eye two-dimensionally, describes a pattern of a scanning movement in the eye. The inventive method uses a displacement device that guides the center of the pattern of movement into the pupil or macula center of the eye, and a determination device that uses the pattern of movement of the scanning movement to determine the pupil center or macula center.

  • Publication number: 20120008092
    Abstract: An information system and a method for providing information in correlation with light that is incident on an eye includes a holographic element disposed in front of the eye and a device capable of recording optical signals which detects light that is incident on the eye via the holographic element. The device capable of recording optical signals detects light which is diffracted by the holographic element before the light impinges on the eye such that the diffracted light does not enter the eye.

  • Publication number: 20090184041
    Abstract: A fuel-water filter/separator for threaded connection to a mounting base has a shell and a filtering media positioned within the shell. The shell has an open top end and a substantially closed bottom end. The shell is made of an opaque plastic except for a window in the shell made from a substantially clear plastic. The substantially clear plastic in the window being insert molded to the opaque plastic. The filtering media is positioned within the shell for filtering fuel. The shell defines a water collection portion beneath the filtering media, the window of the shell being positioned such that it overlaps at least a part of the water collection portion to allow water level monitoring.

  • Patent number: 6585838
    Abstract: A process for enhancing the pleatability of a meltblown web uses ultrasonic bonding wheels to create bond lines in the machine direction as the web is being produced. In addition to, or in place of, the bond lines, ribbons made of the web material, a thermoplastic polymer, string saturated with a phenolic or ultraviolet curing resin, or beads of an ultraviolet curing resin may be ultrasonically bonded to the web to enhance its stiffness. A heated scoring bar or ultrasonic horn forms pleats in the web by heating the web above its glass transition temperature and deforming the web into the pleated configuration. Cooling of the web locks the pleats into position.

  • Patent number: 6207571
    Abstract: In accordance with the present invention, there is provided a method for fabricating a contact on an integrated circuit, such as a DRAM. The method includes the following steps. A gate stack is formed on the integrated circuit. A spacer is formed on sidewalls of the gate stack. An insulating film is formed on the integrated circuit. The insulating film is planarized. Finally, a gate contact opening is formed through the planarized insulating film. In one embodiment, the gate contact opening is formed by removing the insulator, spacer and insulating film by etching. In this embodiment, the insulator, spacer and insulating film are etched at substantially similar rates. As a result, the integrated circuit is tolerant of mask misalignments, and does not over-etch field oxide or create silicon nitride slivers. In another embodiment, the planarizing step is performed with chemical mechanical planarization to form a substantially flat topography on the surface of the integrated circuit.

  • Patent number: 6051501
    Abstract: A method used during the formation of a semiconductor device including a semiconductor wafer assembly comprises a first step of forming a first mask over a front of the wafer assembly such that a portion of first and second layers are uncovered by the mask. Next, the uncovered portion of the second layer is etched to form at least one sidewall in the second layer. A film is formed over the sidewall and, subsequent to forming the film, at least a portion of a third layer on a back of the wafer assembly is removed. During this removal, the sidewall is protected by the film. After removing the third layer, a second mask is formed over a portion of the first and second layers and the first layer is exposed.
