Technical Examples
- An electronic ballast circuit for a handheld fluorescent task lamp, comprising a self-starting electronic driver circuit operated by a power supply and operable to start and run at least first and second compact fluorescent bulbs from a single output; first and second receptacles for connecting the first and second bulbs to the single output; and a bulb accommodation circuit in the electronic driver circuit that enables operation of the electronic ballast circuit with either starter or non-starter type fluorescent bulbs and with either one or both bulbs.
- A handheld fluorescent task lamp comprising a housing assembly having a housing and a tubular lens body enclosing compact fluorescent bulbs, an elongated spine configured for slidingly supporting the lens body, and a resilient bulkhead for cushioning the compact fluorescent bulbs in the lens body; an electronic ballast circuit within the housing comprising a power supply, a self-starting electronic driver circuit operable to start and run at least first and second CFL bulbs; a bulb accommodation circuit that enables operation of the electronic ballast circuit with either starter type or non-starter type and regardless whether one or both CFL bulbs are connected to the driver circuit; and an illumination assembly, wherein the CFL bulbs are oriented with respect to each other such that an enhanced forward emission field is provided.
- A method for driving a flash memory and flash memory apparatus thereof are provided. The flash memory apparatus comprises a flash memory controller and a flash memory. At first, a voltage level of the parameter definition pin is detected by the flash memory controller to obtain the basic configuration of the flash memory when the flash memory controller is in a reset mode. Next, a fundamental access operation is performed on the flash memory by the flash memory controller according to the basic configuration. Then, a detail configuration is read from a specific data block of the flash memory. At last, the flash memory is driven according to the basic configuration and the detail configuration of the flash memory.
- A probe mark reading device for reading probe marks stormed on electrode pads of semiconductor chips contained in a semiconductor wafer (90), comprising a CCD camera (20) for taking an image of the semiconductor wafer (90) and outputting the image as an image signal Si, an optical unit (21) for optically enlarging a location to be photographed by the CCD camera (20), a light source (30) for illuminating the location to be photographed by the CCD camera (20) with a flash of light generated for a short period of time from when a flash signal Sf is provided, an X-Y stage (40) capable of changing a position to be photographed by the CCD camera (20) based on a motor control signal Sm by moving a mounted semiconductor wafer (90) in an X-direction and a Y-direction, and a computer (10) for providing control and saving the images after receiving and trimming the image signal Si. With the above configuration, it is possible to read probe marks in a short time without a user having to expend much time or effort.
- The present invention concerns a digital still camera (1). This camera carries out a framing process by using an infrared pick-up image and a visible light photographing by using a flash or a low speed shutter in a still image pick-up process. Upon automatic focusing, the light of an auxiliary visible light source (23) for automatic focusing is emitted to apply the visible lights and carry out an automatic focusing process. In the digital still camera, the framing process can be carried out which allows the image of a subject which is to be picked up to be displayed on a finder even under an environment of low illuminance such as photographing a dark place and a user to recognize the contents of the photographed image. Further, after that, even when the visible light photographing is carried out through the irradiation of flash or the low speed shutter, an accurate focusing can be realized.
