摘要:
When an N-times density binary image having N+1 tones is compressed, only the tone of each pixel is converted into a compressed code. The compressed code has a number of bits necessary and sufficient to distinguish between the tones. When a triple-density image having 4 tones is compressed, for example, the tone of each pixel is converted into a 2-bit compressed code. When the original N-times density is restored from the compressed code, there is formed a dot pattern in which the number of dots corresponding to the tone, as represented by the compressed code of each pixel, are situated closer to the darker one of the two adjoining pixels.

A laser scanning microscope separates fluorescence signals of different fluorophores in accurate unmixing by eliminating positional pixels shifts between different fluorescence images obtained through irradiation of different-wavelength laser lights. The microscope includes a laser light source capable of emitting a wavelength-changeable laser light, a correction amount determination unit that determines a correction amount for correcting an optical axis shift of the laser light, an optical axis adjusting unit that adjusts an optical axis, a scanning unit that performs two-dimensional scanning, an objective lens that focuses the laser scanning light to a specimen and fluorescence emitted from the specimen, a light detector that detects the fluorescence, and a control unit that changes the wavelength of the laser light synchronously with the scanning by the scanning unit while controlling the optical axis adjusting unit based on the correction amount determined by correction amount determination unit.

An operating state determining device can determine whether or not an engine is in a certain operating state. A mode setting device can disable mode setting into a speed setting mode if a certain operating state of the engine has been determined, and can enable mode setting into the speed setting mode if the engine is not in the operating state.

A small watercraft can include an outer surface member forming an outer surface of a watercraft body, and a luminous body attached to the outer surface member and configured to radiate light outside of the watercraft body. At least a portion of the luminous body can be embedded at a portion of the outer surface member.

There is generated a virtual tile set which virtually covers color planes of an original image without any clearance or overlap by combination of Penrose-type virtual tiles to be non-periodically provided on the planes. The respective tiles are subjected to raster conversion in accordance with predetermined gradation levels, thereby generating a raster image. Since the virtual tiles can be laid non-periodically, iteration of the same dot pattern on the raster image can be prevented.

A watercraft has an engine that is controlled by an electronic control unit and the watercraft includes a security system. The security system includes a portable transmitter unit, and also includes a mounted receiver. The portable unit is waterproof and is buoyant. The portable unit includes a housing of transparent material that allows a user to see whether water has entered the portable unit. The security system has an antenna that provides improved reception between the portable transmitter unit and the mounted receiver.

An operation control system for a small boat can include a mode selection module configured to allow a driver to select between a plurality of driving modes including at least a normal operation mode, in which the boat cruises at a speed in response to the displacement of an acceleration controller, and a low-speed setting mode, in which the boat cruises at a preset low speed when a low-speed setting controller is operated; in which the mode selection module permits the driving mode to switch to the low-speed setting mode if the displacement of the acceleration controller is zero, or small or close to zero or is in or substantially at an idle position.

A throttle control system eases operation of the throttle lever on a small watercraft to improve rider comfort. The small watercraft includes an internal combustion engine and a steering mechanism for steering the watercraft. The steering mechanism includes a handlebar assembly. The engine includes an air induction system that supplies air to the engine and includes a throttle device configured for controlling the amount of air supplied to the engine. The control system includes a throttle operator, an operator position sensor, a controller and an actuator. The throttle operator is located on the handlebar assembly. The operator position sensor is configured to detect the position of the throttle operator and to communicate with the controller. The actuator is configured to adjust the throttle device in response to the controller.
摘要:
Several embodiments of personal watercraft having a V bottom hulls that define an engine compartment in which an internal combustion engine is positioned. This engine drives a propulsion device for the watercraft through an appropriate transmission. The engine includes an engine body having an opening into which a fuel injector injects. The fuel injector is positioned so that its spray axis is oriented so that it is not likely to intersect the walls of the engine that define the opening regardless of the angular position of the watercraft in the body of water in which it is operating. Both direct and manifold injected and two and four cycle engines are disclosed.
