Received signal strength indication link like other metrics such as travel time measurement (time of arrival). Received signal strength indication In telecommunications, received signal strength indicator (RSSI) is a measurement of the power present in a received radio signal. RSSI is usually invisible to a user of a receiving device. However, because signal strength can vary greatly and affect functionality in wireless networking, IEEE 802.11 devices often make the measurement available to users. RSSI is often derived in the intermediate frequency (IF) stage before the IF amplifier. In zero-IF systems, it is derived in the baseband signal chain, before the baseband amplifier. RSSI output
Presence sensing device safety of a press brake operator while employing the precision of lasers directly surrounding the die. OSHA's caveat to its approval of the device was that they be properly installed and inspected. Among other presence sensing devices available, this device can be used as a retrofit to aging machines. Cameras are another electronic safety device used for press brake safety. The camera can detect an intrusion between the upper and lower dies. If an intrusion is detected, a signal will stop the downward movement of the ram. A camera safety system uses a linear scale to calculate the upper beam's
