  • Patent number: 7705877
    Abstract: A method for displaying facial features includes generating an image with facial features on a nonplanar surface and positioning the image on the nonplanar surface to indicate a direction of gaze and enhance nonverbal communication associated with the facial features. The apparatus for displaying facial features includes a nonplanar surface, an image generation device that creates an image with facial features on the nonplanar surface and a positioning system that positions the image on the nonplanar surface to indicate a direction of gaze and enhance nonverbal communication associated with the facial features.

  • Patent number: 7391635
    Abstract: An apparatus and method for storage and retrieval of memory content including a storage structure containing a plurality of memory elements addressable as a two-dimensional array of memory content values, a reading circuit capable of retrieving the memory content values from a region of the two-dimensional array varying in size according to the desired memory readout resolution, an aggregating circuit capable of totaling the memory content values of the memory elements addressed by the reading circuit to produce an aggregate memory content value and a normalizing circuit capable of scaling the aggregate memory content value according to the number of memory elements in the contiguous region to produce an average memory content value of the desired memory readout resolution.

  • Publication number: 20020100889
    Abstract: This invention relates to a method and apparatus for high-speed fluid flow control. More particularly, the invention is directed to a valve formed, at least in part, of an actuating material, such as piezoelectric or anti-ferro-electric material. The valve is used for controlling fluid flow (including air flow) in a variety of devices including imaging devices (e.g. printers, copiers, etc.) for which air flow is used to handle paper. In one embodiment, the subject valve takes advantage of the phenomenon of buckling, resultant bistability and other structural mechanics to efficiently, and in a high-speed manner, open and close to regulate fluid flow. In another embodiment, the valve includes implementation of the actuating material to bend an s-shaped blocking element within the valve. The valve is also advantageously implemented in matrices and formed using batch fabrication techniques.

  • Publication number: 20020043633
    Abstract: This invention relates to a method and apparatus for collecting or collimating light for detection. More particularly, the invention is directed to a technique for detecting the edge of an object using an apparatus having a plurality barriers or shield structures that are advantageously aligned with an optical sensor array to collect or spatially filter generated light for improved detection of the light. The invention also relates to methods of forming the structure. Application of the invention is found in the field of detecting edges of objects such as sheets of paper that are fed through imaging devices along a paper path.

  • Patent number: 6284352
    Abstract: A low cost, reusable electric paper that uses ferrofluidic colored fluids and an external magnetic writing instrument. The paper can be formed from laminated rolls of polymeric media that are roller die cut, inked, aligned, bonded and cut to an appropriate size. The paper is formed from layers that define a hidden reservoir and a visible reservoir for each of an array of print cells that form a grid on the paper. A ferrofluidic coloring fluid is permanently contained within the paper and can move from the hidden reservoir to the visible reservoir. The size of the cells define the resolution of the paper. Initially, the paper appears white. However, after passing a writing instrument, such as a stylus, over desired print cells, these cells switch from a first hidden bistable state to a second visible bistable state. In the second visible bistable state, the ferrofluidic coloring fluid forms a desired image in a desired color or colors.

  • Patent number: 5951006
    Abstract: A decoupling mechanism is provided for passively or actively decoupling an exhaust from a modular air transport system by diverting an amount of air exiting a channel in a first module in a direction other than the process direction through use of the Coanda effect. This decouples the amount of air from a downstream module. This is achieved by providing edge surfaces of the channel outlet, formed on top and bottom plates of the first air module, so that one of the two edge surfaces has a larger radius of curvature than the other. An air vent formed by a gap between the other of the edges and the second module is also provided to assist in the Coanda effect.
