摘要:
The invention concerns a method of detecting from a vehicle a bend in a road comprising a surface and road edges, comprising the following operations: taking an image of a road scene unfolding in front of the vehicle and at least partly illuminated by the vehicle, determining, for each pixel in the image a light decrease gradient, analysing these decrease gradients and determining an image of the road edges, mathematically discriminating the gradients from the image of the road edges, analyzing this discrimination and determining edges, and an angle of the bend. The invention also concerns a system for implementing the method of the invention comprising a camera mounted in the vehicle, an image processing unit and a neural network.

An optical system is disclosed which is capable of improving of its contrast characteristic and displaying of images which have a brightness according to the brightness of the use environment. The optical system comprises an optical integrator which divides and recombines the illumination luminous flux in a first axis direction and a light intensity distribution converter which converts the light intensity distribution of the illumination luminous flux in a second axis direction. The optical system further comprises a luminous flux limiting unit which has an aperture. The size of the aperture is changeable in the second axis direction and unchangeable in the first axis direction.

A computer simulation enhanced exercise device is provided which engages the user by directly relating the users exercise motion in real time to a visual simulation or interactive game. The exercise device may comprise any variety of machines including, stationary bikes, rowing machines, treadmills, stepper, elliptical gliders or under desk exercise. These exercise devices are configured with sensors to measure physical movements as the user exercises and are coupled to computer hardware with modeling and virtualization software to create the system. These sensor measurements are then sent to a computer for use in the physics based modeling and real-time visual simulation. The computer simulation enhanced exercise device is further provided with features including manual and automatic adjustment of resistance levels, visualization of accurate caloric burn rates and correlation to everyday food items, and network connectivity providing for multiplayer network simulations and directed advertising.

A system and method are disclosed for reducing interference in simultaneous wireless LAN (WLAN) and wireless personal area network (PAN) signal handling in mobile wireless terminals having both a WLAN and a PAN interface. The wireless terminal includes a first transceiver operating in the PAN network in a communications band and a first communications protocol transmitting first data units. The wireless terminal also includes a second transceiver operating in the WLAN network in substantially the same communications band and a second communications protocol transmitting second data units. The wireless terminal further includes a controller coupled to the first and second transceivers, assigning a higher transmission priority to the second data units than to the first data units when transmission of the second data units overlaps a first occurring transmission of the first data units, to abort transmission of the first occurring data unit. The controller assigns a higher transmission priority to the aborted first data unit than to the second data units when transmission of the second data units overlaps the retransmission of the aborted first data unit, to transmit the aborted first data unit.
摘要:
A screw pump includes a housing and a pair of intermeshing screw rotors. The housing has an inlet port and an outlet port. Each rotor has a first portion whose lead angle decreases. The first portion and the housing form an inlet space and a pump space. Winding angle of the first portion has a first region and a second region. The first region is located in a predetermined range from the end on the first portion adjacent to the inlet port toward the outlet port. The second region is located adjacent to the first region. Reduction rate of the lead angle of the first portion in the first region is set smaller than that in the second region. The maximum lead angle of the first portion is set smaller than a lead angle which decreases at a constant rate in the first region and the second region.

An object of this invention is to provide a structure which meets a high-quality reading requirement and realize high-speed color reading when the reading section of a color image forming apparatus adopts a color contact image sensor using CCDs as reading elements. In order to achieve this object, the image sensor of a color image reading section uses a color contact image sensor in which a plurality of CCDs are aligned as reading elements in the main scanning direction. In this case, each CCD has one analog shift register for RGB time-division reading, and three R, G, and B reading apertures arranged parallel to each other at a pitch corresponding to the reading resolution. The pixel pitch in the main scanning direction is constant.
