Sounds of North American Frogs is a 1958 album of frog vocalizations narrated by herpetologist Charles M. Bogert. The album includes the calls of 57 species of frogs in 92 separate tracks. The album was released on the Folkways Records label as part of its Science Series. By the 1990s, the album had developed a cult following and was featured ...
A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors . PIR sensors are commonly used in security alarms and automatic lighting applications.
The controller opens the tube connected to the valve, allowing that valve to open. Most newer systems employ electromechanical or electronic controllers. In this scenario, the controller is connected to an electrical circuit that operates a solenoid attached to each valve (solenoid valve). When the solenoid is actuated, the water above the ...
Leap Motion, Inc. (formerly OcuSpec Inc.) [1] [2] was an American company, active from 2010 to 2019, that manufactured and marketed a computer hardware sensor device. The device supports hand and finger motions as input , analogous to a mouse , but requires no hand contact or touching.
However, initial size, power consumption and price had prevented their mass adoption in consumer electronics. While there are other kinds of motion detector technologies available commercially, there are four principle types of motion sensors which are important for motion processing in the consumer electronics market.
The Pacific tree frog (Pseudacris regilla), also known as the Pacific chorus frog, has a range spanning the Pacific Northwest, from Northern California, Oregon, and Washington to British Columbia in Canada and extreme southern Alaska. [2] They live from sea level to more than 10,000 feet in many types of habitats, reproducing in aquatic ...
In captivity, C. cranwelli and C. ornata are the most popular species, [4] along with the "fantasy frog", a captive-produced hybrid between C. cranwelli and C. cornuta.These frogs can live in a terrarium with a floor area 8-10 times the size of the frog. [4]
