An RFID Based Smart Feeder for Hummingbirds
We present an interdisciplinary effort to record feeding behaviors and control the diet of a hummingbird species (Phaethornis longirostris, the long-billed hermit or LBH) by developing a Radio Frequency Identification (RFID) based smart feeder. The system contains an RFID reader, a microcontroller, and a servo-controlled hummingbird feeder opener; the system is presented as a tool for studying ...

متن کاملShort Paper: Considerations for the Design of an Epipelagic Biomimetic Electrostatic Imaging Element
We discuss the development and design of a Biomimetic Electrostatic Imaging (BEI) element for use in a future multichannel imaging instrument. Inspiration for electrostatic sensing is provided by the diverse species of fish that use passive and induced electric fields for hunting, defense, localization, and communication. Designing an electrostatic sensor is not without its challenges. Hardware...
متن کاملFeeder use patterns in group-housed pregnant sows fed with an unprotected electronic sow feeder (Fitmix).
Previous studies on feeder use in group-housed pregnant sows focused on dynamic groups and protected electronic sow feeders (ESF). This study observed 60 pregnant sows, 1st to 8th parity--housed from Day 29 of pregnancy to 1 week before parturition in stable groups of 20 animals, 1 Fitmix feeder per group. Data from 25 nonconsecutive 24-hr feeding cycles showed sows making several visits to the...
متن کاملAn electrostatic voltmeter
An electrostatic voltmeter possessing several unique features is described. The size is a minimum for such instruments, since the potential difference is applied to two electrodes, the geometrical arrangement of which is analogous to concentric spheres. The inner electrode is supported on the end of an insulating bushing introduced through the outer electrode, which is a metal can. The inner el...
