  • Publication number: 20190196441
    Abstract: A method for controlling and adjusting a machining parameter of a processing machine detects and acquires information of workpieces during processing, and calculates an error compensation depending on the detected information and a mathematical model. The error compensation is compared with a first preset value and a determination made as to whether the error compensation is greater than a first preset value. The machining parameter is adjusted when the error compensation is not greater than the first preset value, the processing machine can be stopped if greater. An apparatus, and a non-transitory computer readable medium for controlling the machining parameter are also disclosed.

  • Publication number: 20180009469
    Abstract: A method of operating an electric power assisted steering system of the kind in which an electric motor applies an assistance torque to a part of the steering system as a function of an assistance torque signal, the assistance torque reducing the force required by the driver to turn a steering wheel, comprises during normal operation generating an assistance torque signal that is dependent on the torque applied by the driver, and during a fault operation in which the torque applied by the driver is not reliably known to the system generating an assistance torque signal that is derived from a first term that has a value that varies as a function of the angular position of the steering relative to a changeable datum, the angular position of the changeable datum being updated in the event that the direction of rotation of the steering changes.

  • Publication number: 20170211781
    Abstract: An apparatus, system, and/or method that integrates excitable light emitting materials (that are transparent) into any surface to display an image. Light emitting materials may be integrated into uneven, irregular, and/or random surfaces, displays may be formed on objects that are not practical for flat panel displays (e.g. steering wheels). Light emitting materials may be integrated onto or into the surface of a flat panel display that is responsive to excitation light of a laser pointer, thus allowing flat panel displays to be more effectively used in presentation applications. Since the light emitting materials are transparent, application of light emitting materials into objects does not obstruct the view of the objects when the light emitting materials are not being used to display images.

  • Publication number: 20100062194
    Abstract: Embodiments relate to light emitting material integrated into the apparatus having an anti-counterfeit pattern. The light emitting material may be configured to emit visible light in response to absorption of ultraviolet light. The light emitting material may include a plurality of light emitting particles, with each of the plurality of light emitting particles having a diameter less than about 500 nanometers. Accordingly, in embodiments, the anti-counterfeit pattern may be invisible under ambient light. However, under ultraviolet light, the authenticity of a product may be identified by emission of light in the form of the anti-counterfeit pattern. In embodiments, the anti-counterfeit pattern may be in the form of a bar code, a computer readable code, and/or a symbol that verifies the authenticity of a product.

  • Patent number: 7537346
    Abstract: Viewable images may be displayed from a substantially dark substrate. Light emitting material may be integrated into a substantially dark substrate. The light emitting material may be configured to emit visible light in response to absorption of ultraviolet light. The light emitting material may include a plurality of light emitting particles and each of the plurality of light emitting particles has a diameter less than about 500 nanometers. For example, emitting visible light from a substantially dark substrate may allow for images to be displayed with relatively high contrast. These high contrast images may appear clearer to a viewer and may result in less eye strain by a viewer.

  • Patent number: 7452082
    Abstract: In accordance with embodiments, viewable images can be created in glass. Viewable images may be created in glass by using a projector which projects ultraviolet light to excite light emitting material. Clear images may be created in glass because the size the light emitting particles in the glass is less than 400 nanometers. In embodiments, the visible illumination of a transparent substrate to display an image is possible, while the transparent substrate remains transparent. Accordingly, for example, drivers of automobiles may view images (e.g. map images) on their windshield while they are driving. As another example, window shoppers may view enhanced advertisements in the windows of stores that they are approaching.

  • Publication number: 20070009083
    Abstract: System and method of a compact X-ray imaging detector for dental imaging applications are disclosed. In one of the preferred embodiments, a compact X-ray point source is placed in patient's mouth whereas a X-ray detector is placed outside. The preferred improvement offers several advantages over prior art practices. One of the advantages is the much-reduced X-ray exposure to only areas to be imaged. An additional advantage is the improvement on image resolution due to geometric magnification associated with the location of the detector. The third substantial improvement is the enhanced contrast due to reduction of off-axis scattering. In another preferred embodiment, an X-ray imaging detection system is disclosed. The X-ray imaging system consists of a compact X-ray source that can be placed into a patient's mouth, an optical detector with scintillator, system control and an interfaced computer.
