Abstract: A testing system and method incorporate a test signal generator for generating a test signal with multiple tones uniformly distributed across a wideband having a specific bandwidth. This test signal is generated based on user-specified test signal parameter(s) (e.g., using an orthogonal frequency-division multiplexing (OFDM) spread spectrum technique) and processed (e.g., converted from digital to analog or shifted to a different wideband having the same bandwidth), as necessary, so that it is suitable for application to a specific device under test and so that the tones account for the full range of frequencies with the wideband operation of that device under test. After it is applied to the device under test, the resulting output signal is captured, processed (e.g., converted back to digital or shifted back to the initial wideband), as necessary, and analyzed in order to determine the frequency responses associated with each of the tones.

The electronic scale includes a pressure sensor and a microcontroller. The main body presses on the pressure sensor so that the pressure sensor can measure the pressure from the main body to obtain a pressure signal. The microcontroller analyzes the pressure signal to calculating the total weight of the main body and the servers. The alarm stores a predetermined weight threshold, which is the total weight of the main body and the maximum servers that the main body can bear. The alarm also compares the measured total weight with the predetermined weight threshold. When the measured total weight is larger than the predetermined weight threshold, the alarm alarms.

Abstract: The present invention includes systems, methods and apparatus for continuously, independently and in some cases remotely monitoring the operation of a current interrupter used to test a cathodic protection system, or the cathodic protection system itself, for verification of proper operation. Embodiments of the invention include electronic devices that may be temporarily attached to a current interrupter that is being used to test a cathodic protection system, or directly to the cathodic protection system itself. Embodiments of the invention monitor the activity of an interrupter by sampling the output (voltage and time) to identify the cycle(s) of the interrupter. The invention provides truly independent verification since it does not need to know in advance the sequence or cycle times of the current interrupter being monitored. The information obtained by the invention is output so that it may be provided to a user, displayed, downloaded or stored for future reference.
