Abstract: The wireless channel of the wireless communication system is selectively disrupted or interfered with based on the logical states of the data to be transmitted by an electronic device having no wireless data signal transmitting circuitry. A host device transmits a query packet which includes a header and a series of sub-frames to be received by a receiving device. As each sub-frame is transmitted, the electronic device can selectively disrupt the wireless channel by changing its characteristics such that the receiving device can no longer decode that sub-frame based on channel estimation from the header of the frame. Wireless channel disruption occurs in response to a specific state of the bit of data of a message to be communicated by the electronic device. The receiving device then issues a status reply to the host device indicating which sub-frames are decodable and which sub-frames are undecodable based on the initial channel estimation. The host device decodes the status reply to extract the message.

Abstract: In this disclosure, a system and method for extending WiFi backscatter signal range is disclosed. By nulling a query signal at the receiver end, the receiver is able to more effectively receive a backscatter tag signal that has been generated in response to the query signal.

Abstract: There is provided a system and method for performing non-cooperative sensing analysis with a recipient device over a wireless communication standard. The non-cooperative sensing analysis performed without requiring permitted access to communicate wirelessly with the recipient device. The method including: generating an inspection packet, the inspection packet including a mock media access control address (MAC) address as a sender address and a MAC address associated with the recipient device as a receiver address; transmitting the inspection packet to the recipient device using the wireless communication standard; receiving a response packet from the recipient device, the response packet including the mock MAC address as a receiver address; generating a derivative metric from the response packet; and outputting the derivative metric.

Abstract: A wireless system and methods for non-invasive detection of brain injury that includes a detection device for reliable monitoring and analyzing of sleep movement in comparison with normal sleep movement architecture to identify dampened sleep movement patterns indicative of brain injury.

Abstract: Systems and methods are disclosed that reduce or eliminate interference from non-target sensors in a wireless network. In some embodiments, the sensors contain a blocking device, such as a diode or a transistor, connected between the antenna and the transducer that blocks the cross-correlation response from being transmitted from non-target sensors while permitting an autocorrelation response from a target sensor to be transmitted.
