An apparatus and method for simultaneously testing a plurality of mobile devices is disclosed. The method for simultaneously testing a plurality of mobile devices generally includes simultaneously executing a test mobile device application on the plurality of mobile devices, determining test mobile device application results for the plurality of mobile devices at a plurality of test computers, sending a test mobile device application results from the plurality of mobile devices to the plurality of test computers, and deleting the test mobile device application on the plurality of mobile devices.

Automatic testing/analysis of local loops of telecommunications networks includes obtaining bits-per-tone data for a local loop of a telecommunications network and generating a bit value string from the bits-per-tone data. The bit value string is then analyzed to determine whether it includes a bit pattern indicative of an impairment of the local loop. Further approaches for automatically testing local loops of telecommunications networks include obtaining attenuation data for multiple tones carried by the local loop and determining whether the attenuation data falls below thresholds for providing a service using the local loop.

A receiving device includes a reception unit that samples a sample signal from a DUT 2; an FFT processing unit 21 that performs an FFT process by multiplying the sample signal by a window function; an FFT length setting unit 34 that, when the signal length of the signal to be measured is shorter than the first FFT length conforming to the communication standard, instead of the first FFT length, sets a second FFT length shorter than the signal length of the signal to be measured, as an FFT length of the FFT process; and a window function setting unit 35 that, when the signal length of the signal to be measured is shorter than the first FFT length, instead of a first window function, sets an asymmetric second window function having a peak separated from a center of a window section, as the window function.

The disclosed technology includes at least one method that enables a user of a wireless mobile device to remotely administer test cases that check the performance of telecommunications network nodes. The method includes authenticating a user for a limited time period in which the user can remotely administer the test cases. While being temporarily authenticated, the user can configure the test cases by associating services or operations with particular nodes. The executed test cases cause the nodes to generate data that indicate performance of the nodes in response to the services or operations. The results can be displayed at the mobile device used to remotely administer the test cases.

This disclosure describes a system and method for generating images by performing TEM surveys using pre-existing infrastructure such as transmission lines, or power lines, and naturally occurring transients such as lightning strikes or load switching. A relatively inexpensive sensor array can be installed on overhead power lines (e.g., electrical transmission or sub-transmission lines) which can detect transients in the overhead power lines. Transients in the overhead power lines can cause the power lines to emit pulses of electromagnetic (EM) radiation, which propagate into the earth's subsurface. This sudden change in electromagnetic field in the subsurface can induce eddy currents, which in turn emit return EM radiation that can propagate back to the overhead power line and induce secondary voltage and current transients. The magnitude of these secondary transients, and their time delay from the original transient are influenced by the properties of the subsurface in which the eddy currents formed.

Methods, apparatus, and systems for generating a price of a target device are disclosed herein. An evaluator device obtains technical properties associated with the target device. The technical properties include a make and a model of the target device. Physical properties associated with the target device are obtained. The physical properties include information related to wear and tear of the target device. Obtaining the physical properties includes indicating to a user that the user should position the target device in multiple predetermined positions and that the evaluator device records an image of the target device in each of the multiple predetermined positions. A video of the target device is recorded while the target device is positioned in the multiple predetermined positions. The obtained physical properties are evaluated to generate a condition metric value of the target device. Based on the generated condition metric value, the price of the target device is determined.

Various embodiments of kiosks for purchasing mobile phones and other mobile electronic devices from users are disclosed herein. In some embodiments, the kiosks include an apparatus to position an electrical connector for connection to a mobile device. This apparatus enables the kiosk to connect to the mobile device to electrically inspect the mobile device, and the associated electrical connectors and cables are not subjected to repeated pulling and other rough handling that can lead to premature wear and tear. Accordingly, use of connector carriers configured in accordance with the present technology can lead to longer connector/cable service life, reduced maintenance, and greater kiosk up-time. In some embodiments, the apparatus can include a camshaft having one or more cam lobes positioned to act against one or more cam followers, e.g., carrying one or more electrical connectors.
