12 results about "Radiotelephone" patented technology

A radiotelephone (or radiophone) is a communications system for transmission of speech over radio. Radiotelephone systems are very rarely interconnected with the public switched telephone network, and in some radio services, including GMRS, such interconnection is prohibited. "Radiotelephony" means transmission of sound (audio) by radio, in contrast to radiotelegraphy (transmission of telegraph signals) or video transmission. Where a two-way radio system is arranged for speaking and listening at a mobile station, and where it can be interconnected to the public switched telephone system, the system can provide mobile telephone service.

Systems and methods for secure wireless transmission of power using unidirectional communication signals from a wireless-power-receiving device

An exemplary embodiment of secure wireless transmission of power using unidirectional communication signals from a wireless-power-receiving device. The method includes, receiving, from a wireless-power-transmitting device that includes a first communications radio, a first wireless-power-transmission signal at a wireless-power-receiving device that includes a second communications radio. In response to receiving the first wireless-power-transmission signal: broadcasting, via the second communications radio of the wireless-power-receiving device and without establishing a communications channel between the first and second communications radios, a data packet, the data packet including information identifying (i) at least one power requirement of a power source of the wireless-power-receiving device (ii) an amount of power received by the wireless-power-receiving device from the first wireless-power-transmission signal. After broadcasting the data packet, receiving, from the wireless-power-transmitting device, additional wireless-power-transmission signals at the wireless-power-receiving device, wherein the wireless-power-transmitting device transmits each of the additional wireless-power-transmission signals using a predetermined sequence of different transmission characteristics.

Foot-mounted sensor systems for tracking body movement

A method is disclosed for foot sensors to be used to determine at least two characteristics of a subject's activity by using a combination of sensors for force and foot orientation / motion / position. A wearable footwear ecosystem is comprised of the subject's footwear, sensor-enabled insoles or insertable devices, in- or on-footwear electronics that is hard wired to the sensors and may contain additional sensors such as accelerometers, a master device and means to communicate (typically wirelessly) among the various sensor platforms, and the master device including clock synchronization. Correlating the time stamps for data among various sensors, and the master device communicating wirelessly is critical to accurate determination of the desired characteristics. Multiple force-sensitive resistors on a common substrate are individually optimized for dynamic range. Pulse sensors using arrays of such force-sensitive resistors are implemented. The resultant system can profitably be used for gaming, biometric monitoring, and activity tracking.

System and method for isolating and locating wireless phones

A system for locating a mobile communication terminal, the system having an interrogation device, which is configured to solicit a mobile communication terminal of a wireless communication network to establish temporary communication with the interrogation device in an original bandwidth employed for communication between the interrogation device and the mobile communication terminal. Processors configured to isolate the uplink bandwidth of the mobile communication terminal by: configuring the interrogation device to remove a downlink bandwidth, to the wireless communication terminal, from an end of the original bandwidth to create a new downlink bandwidth; calculating an uplink bandwidth at the end of the original bandwidth to be less than the bandwidth removed from the downlink bandwidth; and reconfigure the mobile communication terminal to uplink to the interrogation device on the calculated uplink bandwidth at the end of the original bandwidth. The system further comprising a power detection device (PDD) configured to measure a power of a radio frequency (RF) signal emitted by the mobile communication terminal and having bandwidth filter configured to measure less than a calculated uplink bandwidth and locate the mobile communication terminal.
