Electric Circuits Simulator vs WingID

The virtual laboratory stand «Relay-Contactor Circuits for Electric Drive Control» is intended for simulation training in the principles of constructing relay-contactor control circuits for a three-phase asynchronous electric drive using standard electrical components – circuit breakers, contactors, relays, push-button posts, etc. Main functions of the software product: - Construction and editing of a schematic diagram of an electrical circuit; - Construction and editing of a simulation model of a laboratory stand; - Software simulation of an assembled electrical circuit with the ability to interactively change the state of devices; - Simulated measurement of voltage in a circuit using a virtual multimeter; - Working with user project files; - Interaction with a physical relay board to implement software control of the electric drive (optional). The graphics component of the software uses the OpenGL 2.0 component base.

Help us study and preserve waterfowl populations — one wing at a time. WingID is a conservation field tool that lets hunters contribute wing photos to scientific research. Your submissions help biologists track population health, understand breeding success, and set sustainable harvest limits that protect waterfowl for future generations. WHY WING SURVEYS MATTER Wing feathers reveal species, age, and sex — critical data that guides wildlife management decisions across North American flyways. Traditional wing surveys rely on mailed envelopes and limited participation. WingID makes contributing as easy as taking a photo. HOW IT WORKS • Snap a photo of your harvested bird's wing • Confirm or challenge the species verification from our custom model • Submit for expert verification by wildlife biologists • Track your contributions and conservation impact RESEARCH PARTNERS Your data supports ongoing studies at UC Davis Waterfowl Lab and LSU School of Renewable Natural Resources. Every verified submission strengthens the scientific foundation for waterfowl conservation. BUILT FOR HUNTERS, BY HUNTERS WingID is brought to you by BlindBook, the trusted hunt management platform, and powered by WaterfowlAI conservation technology. We're building the largest hunter-contributed wing dataset — and we need your help. JOIN THE EFFORT Whether you're a seasoned waterfowler or new to the blind, every wing counts. Download WingID and turn your harvest into conservation data.
