Abstract: A CT scanner and method of operating the CT scanner enables customized automated selection of tube current and peak tube voltage for a CT scan. The CT scanner receives data, each datum of which corresponds to a reference image quality (noise level at a certain tube voltage) for patient water equivalent diameter (“WED”) body size. The CT scanner then stores the noise level and patient WED, and a processor in the CT scanner generates a curve corresponding to acceptable noise levels as a function of water equivalent diameter. The CT scanner stores the curve in a memory associated with the scanner and the CT scanner is subsequently operated with reference to the curve stored in the memory. The tube voltage that can generate the reference CT scan quality (signal-to-noise ratio) with the lowest radiation dose to the patient is selected.

Abstract: A hazard warning device for vehicles is provided, including a light source unit, a light guiding unit, a warning structure unit and a control unit. The light source unit generates a light source for warning. The light guiding unit guides the light source to become a surface light source having an area. The warning structure unit scatters or reflects the surface light source and displays a warning. The control unit is the element for controlling the on and off of the light source unit. When the control unit receives an activation signal from a vehicle, the control unit activates the light source unit and displays a warning on a surface area of the vehicle through the light guiding unit and the warning structure unit.

Abstract: A polishing pad, comprising a mounting surface and an opposing polishing surface with a polishing pattern having at least one aperture thereon, is formed with an adhesive layer adhered to the mounting surface with uniform adhesive strength therebetween. Embodiments include applying an adhesive layer to the mounting surface with uniform pressure prior to forming the polishing pattern on the polishing surface. Embodiments also include forming the polishing pattern having at least one aperture, forming a fitter having a surface pattern opposite to the polishing pattern and having a projection, positioning the fitter on the polishing pattern so that the projection fills the aperture in the polishing pattern forming a composite having substantially parallel opposing surfaces, applying pressure to bond the adhesive layer to the mounting surface with substantially uniform adhesive strength therebetween, and removing the fitter.

Abstract: A projector includes at least one light source module, an optical system, an imaging unit, and a projection lens. Each light source module includes a lamp unit and a heat-dissipating module in close contacting with the lamp unit.

Abstract: A sterilizing device comprises a light guiding member and an ultraviolet (UV) light source. The light guiding member has a surface. The UV light source emits UV light rays such that the UV light rays are guided into the guiding member based on a total internal reflection. When an object contacts or comes close to the surface, an evanescent wave from the UV light rays irradiates on the object.

Abstract: An electronic device with automatic switching input interfaces and a switching method thereof. The electronic device supports an Advanced Configuration Power Interface (ACPI), and includes a display unit, a storage unit, a memory unit, and an embedded controller. The display unit can be changed to a first position or a second position, and sends a signal to an embedded control unit when the display unit is at different positions. A management program running in the electronic device queries the ACPI and the embedded control unit to check the position and state of the display unit, so as to automatically load and run a corresponding program of a virtual input interface or a physical input interface into the memory unit, and remove the other program from the memory unit at the same time.
