The present disclosure provides an apparatus, method and system for use with a vehicle having passive keyless entry and start (PKES) system including a vehicle unit and a key fob storage unit. The vehicle united is to be installed with the vehicle having a first transceiver, a first relay transceiver an authentication unit, a first controller for controlling said first relay transceiver allowing said transmission if said user is authenticated. The key fob storage unit comprises at least one housing for securely holding at least one key fob associated with said PKES systems of said vehicles, a second, said second wireless relay w wherein said first relay transceiver and said second relay transceiver allows said PKES system and said key fob to communicate from a distance larger than a range of said PKES system signals.

Systems, apparatuses, and methods are described for a privacy blocking device configured to prevent receipt, by a listening device, of video and/or audio data until a trigger occurs. A blocker may be configured to prevent receipt of video and/or audio data by one or more microphones and/or one or more cameras of a listening device. The blocker may use the one or more microphones, the one or more cameras, and/or one or more second microphones and/or one or more second cameras to monitor for a trigger. The blocker may process the data. Upon detecting the trigger, the blocker may transmit data to the listening device. For example, the blocker may transmit all or a part of a spoken phrase to the listening device.

A method for providing localized jamming effects includes using a processor onboard a vehicle to perform the steps of: receiving a jamming command to simulate a jamming effect on a particular sensor onboard the vehicle; and generating a jamming effect in a model of the particular sensor in response to the jamming command. The jamming effect in the model of the particular sensor simulates the jamming effect on the particular sensor being generated by an entity other than the vehicle.

The subject method for delivering power to a moving target wirelessly via electromagnetic time reversal can find applications in wireless electrical transmission to portable devices, wireless heating of portable devices, novel wirelessly powered accelerometers, hyperthermic treatment of cancers, and many other applications. The subject non-linear time reversed electromagnetic waves based wireless power transmission (WPT) system targets either a single linear or non-linear object where a selective targeting between two diodes has been demonstrated simultaneously with different degrees of non-linearity in a three-dimensional ray-chaotic billiard model. A dual-purpose rectenna with harmonic generation for wireless power transfer by non-linear time-reversal has been designed for the subject system using the Schottky diode.

A test system, is provided, which relates to a technical field of detection devices, and particularly to a test system of an artificial intelligence terminal. The test system comprises: a signal shielding box, a test unit, a control terminal and a server; the test unit is disposed in the signal shielding box; a router of the test unit is in wired connection with a to-be-tested terminal; the control terminal is in wired connection with the router; and the server is in wired connection with the router. Through the signal shielding box, the signal transmission between the router and the to-be-tested terminal is effectively shielded from external signals. In addition, due to the wired connections, the stability of the signal transmission is ensured, which solves existing problems of unstable signal transmission and signal crosstalk during signal transmission using wireless transmission technologies.

A signaling-type method for mobile phone signals, comprising: establishing a shielding processing system, and ensuring that the frequency reference of said system is synchronized with that of a base station; using the feature that a frame signal of a base station is repeatedly transmitted according to a frame period of the base station, receiving the frame signal of the base station at different times; performing filtering processing on the frame signals of the base station using a frame averaging method, so as to obtain purified frame reference signals of the base station; and using the purified frame reference signals to shield the base station.
