    摘要: A presentation system for a presenter to safely point out parts of an image projected from a projector onto a screen with laser light projected from a laser pointer held by the presenter is disclosed. The presentation system includes one or more infrared light receiving units on the laser pointer that selectively receive infrared signals from sending units that are mounted on the projector or on walls in order to control emission of laser light from the laser pointer. Arrangements of the sending and receiving units are designed to allow emission of the laser light from the pointer only when the laser pointer is pointed toward the projection screen. A control unit in the laser pointer may determine if the laser pointer is pointed correctly or a gravity operated shutter may further assist in preventing unsafe projection of laser light from the laser pointer.

    摘要: A presentation system comprises a display for setting a virtual screen, a pointing mark for operating a point on the display, a photographing device for photographing the pointing mark and the display, a displaying device for displaying a predetermined image or the photographed image photographed by the photographing device, and a control device. The control device calculates coordinates of the pointing mark on coordinates of the virtual screen and has a pointing function for synthesizing a predetermined point image at coordinates of the image on the displaying device, which correspond to the coordinates of the pointing mark.

    摘要: A presentation system includes a screen device, a projecting device that projects a visible image onto the screen device, and a laser pointer operated by a user, that projects a laser beam onto the screen device. The laser pointer includes an infrared light emitting section and a laser beam emitting section. A projected image of the infrared light projected onto the screen is sensed by an infrared light sensing section. Movement direction and movement distance of the projected image and button click signal are converted into mouse data usable by computer. An image based on the mouse data from the computer is projected from a projector to the screen. A human body sensor which senses heat of human body existing in a projected direction of the laser beam is settled to supply a safe presentation system by controlling the projection of the laser beam in case this sensor is operated.

    摘要: A first bar code that is reproduced by linearly polarized red light (first read light) parallel to a short-side direction and a second bar code that is reproduced by linearly polarized green light (second read light) parallel to a long-side direction are recorded on a birefringence label. A probe is a reading device that reads the first and second bar codes from the birefringence label and includes first and second light sources and an imaging unit. The first light source emits the first read light to the birefringence label. The second light source emits the second read light to the birefringence label at a time different from that of the first read light. The imaging unit captures the birefringence label through a polarizing plate having a transmission axis aligned with the short-side direction of the birefringence label, and acquires reproduced images of the first and second bar codes.

    摘要: A circuit configuration for realizing high impedance in an address drive circuit is provided in order to reduce the number of recovery switches without reducing power recovery efficiency. A mechanism for realizing the high impedance in an address drive circuit during a sustain period of a plasma display panel is provided. By achieving the high impedance, capacitance coupling between an X electrode and an address electrode and between a Y electrode and an address electrode can be cancelled, and a power recovery circuit can be simplified without reducing the power recovery efficiency.
