摘要： Apparatus and method for sensing the position, size, shape and location orientation of one or more objects (10) in two dimensions. The position sensor uses arrays of light sensors (128) mounted on a substrate (124). When an object (10) passes in proximity to the light sensors (128) light energy (146) from a plurality of light sources (142) is either reflected from the object (10) to the light sensors (128), or is emitted directly to the light sensors (128). The light energy (146) is then converted to individual signals and transmitted through circuit traces (126) in a printed circuit board (110) to a local controller. The information may then be processed to determine the size, position, shape and location orientation of an object (10).

摘要： An apparatus for processing a substrate on two sides. A substrate has a first edge as a leading edge in a process direction and a first side in a face-up orientation. In one embodiment, the apparatus comprises an input pathway (14) for receiving the substrate from a substrate processing station, a station (12) for processing the face-up side of the substrate, a reversion pathway (20,23) for reverting the substrate and returning the reverted substrate to the input pathway. After reversion, a second side of the substrate is in the face up orientation and the first edge is the leading edge. A merge point (21) merges the reverted substrate into the input pathway for processing the face-up side of the substrate in the print station.

摘要： Apparatus and methods that approximately solve an actuation allocation problem by breaking the solution into modules, which may or may not be overlapping. The solution to the actuation allocation problem is expressed in terms of solutions for each of the modules. The solutions for the modules serve as constraints for a solution of the optimization problem on each module. The optimization problem for each module is decomposed into further modules until the modules consist of a small enough number of individual implementation units so that the solution for the module can be solved using conventional optimization techniques.

摘要： A PC board actuator (10) that emulates a muscle fiber includes a first pressure source (16), a second pressure source (15) lower than the first source, at least one expansion chamber (24) alternately communicating with the first and second pressure sources, first (18) and second (20) valves mounted with the PC board (13) that open and close the chamber with respect to the first and second pressure sources, and an actuator member (28) interacting with the expansion chamber to apply a force to the object (35). The actuator is preferably formed using planar batch technology and the valves preferably comprise electrically controllable flap valves mounted on the PC board. Alternatively, the actuator includes antagonistically arranged expansion chambers (24,25) that operatively apply reciprocating forces to the object. In other embodiments, the actuator includes plural expansion chambers arranged in series or in parallel in order to increase the overall extent of attainable displacement or to amplify the force generated by the actuator.

摘要： A low cost, reusable electric paper (100) 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 (126) and a visible reservoir (130) 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.

摘要： A sensor array (29) includes includes multiple sensor elements that each have a collection electrode (35) in contact with a photosensitive layer (33). The photosensitive layer (33) is configured to produce a detectable response at the collection electrode (35) upon incidence of radiation in a responsive zone of the photosensitive layer. A gate electrode layer (31) is separated from the photosensitive layer by a dielectric layer (32), with adjustments to voltage applied to the gate electrode layer (31) inducing changes in areal extent of the responsive zone of the photosensitive layer. Changing the size of the responsive zone permits performance of image convolutions for edge detection, data compression, or other Gaussian convolutions by the sensor array, rather than by post-detection electronics.

摘要： Pixel elements capable of imaging spatial intensity variations within themselves, and displays comprised of such elements, are described. The pixel elements (10) include a resistance layer (14) disposed between at least one set of electrodes (16,22). Over that resistance layer (14) is a liquid crystal material (24). Over that liquid crystal material (24) is a field electrode (26). In operation a voltage, whose components are referenced to the field electrode, is applied across the resistance layer (14). The resulting current flow induces a spatially varying electric field between the field electrode (26) and the resistance layer (14). That spatially varying electric field results in a corresponding response by the liquid crystal layer which results in a spatially varying light transmission through the liquid crystal material. By varying the voltage across the resistance layer (14) and/or the voltage applied to the field electrode (26) varying amounts of light transmission can be achieved.
