Abstract: A method of filtering unwanted motion related artifacts from received sensor-based location data includes receiving unfiltered location data and calculating a plurality of spatio-temporal components associated with the unfiltered location data. The method further includes comparing each spatio-temporal component to the unfiltered location data and updating a weight value based on the comparison of each spatio-temporal component to the unfiltered location data to generate a dynamically updated set of weights. Motion corrected location data is calculated based on the dynamically updated set of weights and the plurality of spatio-temporal components.

Furthermore, the method includes generating the alert for the device in real-time based on the predicted impact of the determined at least one anomaly and receiving feedback on the generated alert in real-time.

Abstract: A continuous ink jet printer has a line (69a) for venting at least some of the air that has been sucked along the gutter line (17), and a line (69b) for recirculating back to the printhead (25) at least some of the air that has been sucked down the gutter line (17). Preferably the relative proportions of vented air and recirculated air can be varied, so as to reduce solvent loss during normal operation but allow increased solvent loss if the ink is over-dilute. Preferably the air recirculated to the printhead is connected directly into the flow path from the gutter orifice to the source of gutter suction, without opening into the space containing the ink jet. This reduces the tendency of solvent in the recirculated air condense on the printhead electrodes.

Abstract: A continuous ink jet printer comprising an ink gun for forming an ink jet; an arrangement of electrodes for trapping electric charges on ink drops of the ink jet and for creating an electrostatic field for deflecting drops carrying trapped electric charges; and a gutter having an ink-receiving orifice for receiving ink drops of the ink jet which are not used for printing; a gutter flow path for flow of ink from the ink-receiving orifice of the gutter, through and away from the gutter; an air recirculation line for conveying at least some of any air that has passed with the ink along at least a part of the gutter flow path so as to re-enter the gutter flow path either through the ink-receiving orifice or through a connection into the gutter flow path downstream of the ink-receiving orifice; and a vent for venting at least some of the air that has passed with the ink along at least a part of the gutter flow path so as not to re-enter the gutter flow path.

The furniture preferably includes rollers arranged at a predetermined orientation so that the furniture prescribes a predetermined circular path, on rotation of the furniture about the vertical axis.

Abstract: A novel approach to cross-talk analysis takes effective account of the nature of cross-talk interference. This approach employs conservative assumptions regarding (1) the equivalent output resistance, and (2) the definition of noise immunity for the victim gate. Also, this approach uses signal and noise current metrics in modeling the parameters of the active device elements. This approach provides an expectation of detection and elimination of noise hazards that might otherwise not be undetected.

Abstract: The method of this invention determines the timing of an integrated circuit design. At each node, the method determines if the timing of signal propagation at that node is critical. If this timing is critical, method calculates the capacitance at said current node using a highly accurate but computationally intensive model. If this timing is not critical, the method uses a less accurate but less computationally intensive model. The method calculates a signal delay for each mode from the drive strength, calculated capacitance and fan-out. This signal delay is compared to a design goal. This method achieves a better trade-off between timing determination run-time and accuracy. Timing criticality can be determined from one or more of conductor length/area, fan-out, logic depth and timing slack.

Abstract: The present invention provides a multiple region vibration-sensing touch sensor that incorporates at least two sets of vibration sensors on a single touch plate, each set of vibration sensors defining distinct touch regions. The vibration sensors detect vibrations indicative of a touch to the touch plate, and are configured to communicate signals representing the detected vibrations to controller electronics for determining information related to the touch input. Touches within each touch region can be distinguished.

Abstract: The present invention provides a rear projection screen that has a light directing element coupled to a support layer. The light directing element directs an image toward a viewer position. The support layer provides the front surface of the projection screen, accessible to a user. Vibration sensors are mechanically coupled to the support layer to sense vibrations indicative of a touch to the front surface. The sensed vibrations are converted into signals that can be communicated to controller electronics to determine information related to the touch input, such as touch input location, touch force, touch implement type, and so forth.

Abstract: An orthodontic flossing implement and method of use thereof, wherein the present implement comprises a handle from which extends a flat, narrow arm, and wherein the tip of the arm comprises a slit or aperture through which a desired length of floss is inserted. The narrow arm, with the length of floss threaded therethrough, may be quickly and simply inserted underneath a selected arch or pass of a brace wire, wherein the length of floss hanging from the arm aperture may then be easily grasped and worked within and along the inter-dental space disposed proximate or behind the selected wire arch. Thereafter, the arm of the flossing implement is retracted and systematically moved between each arch of the wire, whilst maintaining the floss through the aperture of the arm, whereupon each respective underlying inter-dental space may be conveniently and quickly flossed.

Abstract: The opener consists of two hydraulic actuators which are adapted to act along in two different directions in an horizontal plane, one of said directions being parallel or substantially parallel to the surface of the closed and locked door which is to be opened and the other direction being normal to said door surface. Jamb-engaging elements are associated with a first of the actuators, operation of said actuator causing the elements to engage the door jambs very firmly; operation of the second of the actuators pushes the closed/locked door inwardly out of the door frame.
