Pioneering, early pinniped foraging studies used acoustic telemetry such as very high frequency (VHF) radio transmitters to describe at-sea movements [31,32] and formed the basis of our understanding of pinniped foraging. Feeding was inferred from breaks in the VHF signal from diving, assuming t...

Apple on Friday enabled iBeacon location-aware transmitters at all of its U.S. retail stores, giving the company the ability to easily provide product information and allow shoppers to quickly check out via their iPhone. But initial tests byAppleInsidershow the use of iBeacons remains limited a...
The fakes have none of the RF suppression properties of the real thing. They will noise-up around plug-on transmitters and walkie-talkies. The output is about 3db lower than the genuine. (compensated for in the above sound file.) The painted lettering on the mic’s side is uneven and t...
Cameras 71, 73, 75, 77 are respectively linked to transmitters 70, 72, 74, and 76. Each of these transmitters may be configured as equipment, which feeds a radio signal to an antenna for transmission. The antenna may be integrated with the transmitter. Transmitters are well known in the ...
Similarly, a study in the flightless Takahe (Porphyrio mantelli) found that daily energy expenditure increased 7.7% when using bird-mounted radio transmitters that weighed an average 1.8% of the birds' body mass though time budgets of the birds were not affected [27]. The authors suggested ...
