Abstract: Zero-ascend omnispecies (ZAO) attraction system includes a fish passage attraction module that can be deployed in a fishway where water flows downstream. The fish passage attraction module includes a body having a first end and an opposite second end, first adaptor adjacent the first end and second adaptor adjacent the second end. The adaptors are configured to alter water flow fields downstream of the module so as to attract fish to an entrance thereof.

Abstract: An optical subassembly for low-feedback coupling of light from a light source into an optical waveguide such as an optical fiber is described. The optical subassembly has an aspherical lens with surface sag having a rotationally symmetrical sag component without having a cone sag component, and a rotationally asymmetrical helical component for reducing coupling of light reflected from the optical fiber tip back into the laser aperture by causing a significant portion of the reflected light to encircle the laser aperture. The lens shape and the height of the helix are selected so that tight focusing onto the fiber tip is preserved, while the optical feedback is reduced.

Abstract: An apparatus and method for controlling a work tool on a work machine are provided. The work machine may have first and second actuators, each actuator being operable in a vibratory mode and a non-vibratory mode, and each actuator being coupled to the work tool for changing the position of the work tool. The method may include simultaneously (i) operating the first actuator in a vibratory mode, (ii) operating the second actuator in a vibratory mode, and (iii) receiving a command to change the position of the work tool. The method may further include operating the first actuator in a non-vibratory mode to change the position of the work tool while operating the second actuator in a vibratory mode to vibrate the work tool, in response to receiving the command.

Abstract: An optical module is used in an electronic instrument having a camera. The optical module has a circuit board, a photodetector and a lens stage. The circuit board has various types of electronics. The photodetector is disposed over the electronic devices. The photodetector is electrically connected to the circuit board. An insulator is disposed between the photodetector and the circuit board. The lens stage has an optical lens and a receiving chamber for receiving the electronic device and the optical lens. Thereby, an optical module is integrated. The stack structure of the photodetector and the electronic devices greatly reduces the area of the circuit board, so as to reduces the overall dimension of the optical module.
