摘要： A fish screen is presented having a porous surface made of two or more corrugations (e.g., elongated convex shapes) having an at least partially porous surface. The incorporation of a porous area on the corrugations allows increasing the total porous surface area compared to an underlying diversion area. The porous area is a magnification of an underlying diversion area, which reduces the fluid pressure (e.g., impingement forces) acting on the porous area of the screen. The valley between each pair of corrugations is solid, not porous. The solid valley(s) provide two important functions; they provide multiple small solid surface flow channels over the screen surface. These solid channels protect small or weak swimming aquatic organisms from impingement on the screen. That is, once organisms reach the solid channel, they may move along the solid channel free of impingement until they reach the edge of the screen.

摘要： An improved sensor fish with robust design and enhanced measurement capabilities. This sensor fish contains sensors for acceleration, rotation, magnetic field intensity, pressure, and temperature. A low-power microcontroller collects data from the sensors and stores up to 5 minutes of data on a non-volatile flash memory. A rechargeable battery supplies power to the sensor fish. A recovery system helps locating sensor fish. The package, when ready for use is nearly neutrally buoyant and thus mimics the behavior of an actual fish.

摘要： Systems and methods are disclosed for deterring wildlife, such as bats and birds, from drawing too proximate to an operating wind turbine. Wildlife species may be sensitive to transmitted frequencies, such as ultrasonic frequencies above the range of human hearing. For example, bats may avoid areas where ultrasonic frequencies are being emitted, either because the emitted ultrasonic frequency interferes with the echolocation of the bat, or because encountering the ultrasonic frequency is uncomfortable for the bat. In some aspects, acoustic transmitters may be arranged along a length of a blade of a wind turbine. A controller may direct the acoustical transmitters to transmit signals having ultrasonic frequencies to deter wildlife encounters. The controller may direct the transmitters to transmit only during periods where wildlife encounters are likely to occur (e.g. at night, during migration seasons, during favorable weather conditions, or the like).
摘要翻译： 公开了用于阻止诸如蝙蝠和鸟类的野生动物从太靠近操作的风力涡轮机的系统和方法。 野生动物物种可能对传播频率敏感，如超声频率高于人类听觉范围。 例如，蝙蝠可以避免发射超声频率的区域，这是因为发射的超声波频率干扰蝙蝠的回声定位，或者因为遇到超声波频率对蝙蝠不舒服。 在一些方面，声发射器可以沿着风力涡轮机的叶片的长度布置。 控制器可以引导声发射机传输具有超声频率的信号以阻止野生动物相遇。 控制器可以仅在发生野生动物相遇的时段（例如，在夜间，在迁徙季节期间，在有利的天气条件下等等）期间，才可以指示发射机发射。

摘要： A device for counting animal traffic in an aquatic animal passage system includes chutes positioned across the aquatic animal passage system and a sensor positioned to sense an animal moving through or in the aquatic animal passage system. The chutes and the aquatic animal passage system are formed with precast concrete segments and may include a protective liner or coating coupled to their outer surface to protect animals from contacting the outer surface of the precast concrete segments. The sensors may be integrated with the precast concrete segments forming the chutes. Smart concrete segments may be employed as transducers to create an electric field in the chutes, with impedance sensors coupled to the transducers being responsive to changes to the electric field in the chutes caused by passing animals.

The waterway pipe includes: a horizontal waterway pipe (110) that is provided on an embankment; a vertical waterway pipe (120) that extends from each of opposite ends of the horizontal waterway pipe downward; a bottom waterway pipe (130) that horizontally extends from the vertical waterway pipe outward; and a water entering-and-exiting pipe (140) that extends from the bottom waterway pipe upward. The fishway pipe is provided on the waterway pipe and is configured such that the level of water in the fishway pipe is controlled by adjusting the amount of air in the fishway pipe. The control unit includes: a first air supply pipe that is connected to the waterway pipe; and a second air supply pipe that communicates with the fishway pipe.

摘要： An improved fish passage apparatus is combined with hydroelectric power generation to facilitate migration of fish between water bodies of different heights with minimal injury or trauma to fish. It may also be optimized for power generation when fish are not moving through it. The fish passage apparatus comprises a connecting tube providing fluid communication between upper and lower water bodies, an upper valve in the connecting tube adapted to control flow of water to or from an upper water body, a lower valve in the connecting tube adapted to control flow of water to or from a lower water body, and a working tube opening into the connecting tube between the upper and lower valves a working portion of which extends functionally vertical to above a water level of the upper body of water and to below a water level of the lower body and is vented at its top such that water can flow freely in and out of the working portion. The working tube contains a means for restricting flow thereby increasing the safety to fish passing through the connecting tubes.

摘要： A water diversion system includes a hydraulic chute and a chute screen assembly in the hydraulic chute having a wedge wire screen. The water diversion system also includes at least one collection chamber located below the screen configured to collect filtered diversion water which has passed through the screen. The hydraulic chute includes a base, a crest, a sloped accelerator, and an abrupt drop with an adjustable lip, which forms a hydraulic formation in a downstream pool. The hydraulic chute can also include sloped sidewalls, which constrict the flow of water and form fish passage zones. In addition, the chute screen assembly can include a modular panel configured to facilitate construction, maintenance and replacement of the wedge wire screen.
