The building has a fenced-in roof with "a perimeter that can't be broken," Vikse says, and a sophisticated network of video cameras, motion detectors, and beam sensors.
Physical activity was monitored by 3 arrays of 16 infrared light beam sensors and then converted into distance travelled in cm.
Locomotor activity in the open filed was monitored by photo beam sensors that were arrayed in a 2 cm grid to monitor horizontal movements; the data were collected by a microcomputer and processed using software provided by the manufacturer (AccuSacn Instruments, Columbus, OH).
Activity over 10 min was then monitored by 16 infrared beam sensors along the X– Y plane (Ramezani et al. 2011; Burger et al. 2005).
All comparisons are based on animals studied simultaneously in eight different chambers connected to the same O2, CO2 and light beam sensors in an effort to minimize the effect of environmental variations and calibration on data.

This paper suggests to measure instead of this angle a certain distance using a laser beam sensor and then to compute the stance angle from that distance.
The volumetric flow-rate measurement is done by counting vortices using a flat plate placed in the wake and attached to the beam sensor.
A laser beam sensor detects the time at which the animals fall from the rotating beam.
Spout contact and the required animal orientation were ensured by the coactivation of the center spout sensor and an infrared beam sensor located at the rear corners of the platform.
If you are in a hurry and need to get your garage door closed right away, stand in such a way that you cast a shadow over your garage door's beam sensor (but of course don't block the beam itself - just the sunlight that is shining on it) and then press your remote control so that your door will close.
There will also be other sophisticated measures to keep intruders out: closed-circuit cameras, electronic beams, sensors buried beneath the surrounding wall, guards on the gates and armed-response teams ready to race to the rescue when a householder hits the panic button.
