Abstract: A user interface for an application program which displays documents having colored objects on a working output device such as a CRT, and which outputs the document to a target output device such as a printer that has a color gamut different from that of the working output device. The user interface allows selection from among multiple different colors. The user interface of the present invention includes a region that displays multiple different colors or colored objects, at least some of which are selectable by the user, wherein for these selectable colors or colored objects, only in-gamut colors are displayed.

Abstract: An anti-entrapment system for preventing objects from being entrapped by a translating device includes a capacitance sensor positioned adjacent to the translating device and a controller. The sensor has first and second conductors separated by a separation distance and a compressible dielectric element interposed between the conductors. The conductors have a capacitance dependent upon the separation distance. The capacitance of the conductors changes in response to a geometry of the sensor changing as a result of either conductor or the dielectric element deforming in response to a first object touching the sensor. The capacitance of the conductors changes in response to a second conductive object coming into proximity with either conductor. The controller receives a signal from the sensor indicative of the capacitance of the conductors, and controls the translating device as a function of the capacitance of the conductors to prevent the translating device from entrapping either object.

Abstract: The present invention relates to a color management method for the conversion of internal color appearance space color values to CMYK device values, by interpolating CMY values from a plurality of CMY to color appearance space lookup tables, wherein each CMY table is associated with a specific value of K. A target internal color value is received and the relative purity of that color is calculated in the CMY space. Next, a black generation value is calculated using the relative purity of the target color. Finally, one of the plurality of CMY lookup tables is selected based on the black generation value, and a CMYK value is provided based on an interpolation from the selected lookup table. In this way, the present invention is able to control the output K value in a color appearance space to CMYK conversion. Accordingly, colors across a wide relative purity range, including natural images, can be reproduced with better accuracy and higher quality.

Abstract: A baseball tee may include a wrapped ball holder secured to a top end of a slip tube. The bottom end of the slip tube may fit into the top end of a compression nut. The bottom end of the compression nut may be secured to a top of a vertical stem whose bottom end may be secured to a base. The compression nut may compress a gripper ring against the slip tube such that the slip tube may slide up and down with respect to the vertical stem while a force is applied to the slip tube, but otherwise the slip tube stays in place with respect to the vertical stem. The height of the ball holder with respect to the base may thus be adjusted. The top end of the slip tube may be rounded to protect the ball holder as it is struck and forced against the top end of the slip tube. The bottom end of the vertical stem may be secured to the base off center.

Abstract: An application programming interface (API) that provides a common interface between an application program and plural different types of color measuring devices each having at least one color measuring sensor. The API includes plural functions for operating any of the plural different types of color measuring devices. In order to complete an operation performed by at least one of the plural functions, the function that performs the operation must be called a number of times which is different for at least two different types of color measuring devices. For a particular color measuring device, the API provides the application program with flow control data of the number of times that the function must be called. This flow control data preferably can be provided by the function, in the form of a call-again value or as a numerical value, or by a separate function in the API such as a get-device-capabilities function.

Abstract: A fuel level sensor for sensing and monitoring the level of remaining fluid in a container such as a fuel tank for a motorized vehicle is disclosed. The fuel level sensor incorporates an improved float and pivot arm member attached to a hub that rotates about a pivot base. The conventional resistor card technology, commonly found in automotive applications for translating the position of the float into an electrical signal, is replaced by a more reliable non-contact magnetic flux sensing circuit. The fuel level sensor incorporates a magnetic sensor and magnetic circuit in a commonly known and practiced rotational position sensor configuration for determining the angular position of a hub relative to its pivot base, where the hub is attached to a conventional float-arm member and the base remains stationary relative to the fuel container. The preferred embodiment includes a magnetic flux sensor positioned between two movable magnets.

Abstract: A system for mapping an input point to a surface of a color gamut in a color space. A two-dimensional slice of the color space is selected. The two-dimensional slice includes the input point. A projection point in the two-dimensional slice and a projection between the input point and the projection point are determined. An intersection point between the projection and a mathematical approximation in the two-dimensional slice also is determined between points at least substantially on the surface of the color gamut. A new mathematical approximation is determined between points at least substantially on the surface of the color gamut, based on the intersection point. The intersection point is redetermined at an intersection between the projection and the new mathematical approximation. The determination of the new mathematical approximation and the redetermination of the intersection are repeated until the intersection point satisfies a goodness criteria.

Abstract: A motor control system employed in a mechanism including displacers driven by motors, for example, a vehicle seat control system, includes motor operation parameter detection or simulation as inputs to adaptive algorithms to simplify the control system. The adaptive algorithms compensate for the interference with detection of generated or sensed pulses in previous pulse counting implementations. The seat control permits additional functions to be performed without numerous sensors, power controls and robust demands required in previous systems for controlling motors.
