Abstract: Computing systems and methods are described in which video calls or other online communications are established or enhanced among two or more live participants. In some variants one or more preferences are gleaned from a first participant's behavior so as to streamline a call establishment with one or more qualified recipients. Alternatively or additionally, enriched auditory message data may be received privately from a sender without leaving a shared space.

Abstract: A system and method are disclosed for a single action video call that allows a person to video call another person. The single action can be a mouse click over a URL or a button on a website, or a QR scan of a printed promotional advertising. Furthermore, this single action creates a video call between the two people regardless of platform or computing element that they are using. The single action actor can be on smartphone, laptop, or desktop using a browser or a video application. The intended receiver of the video call can also receive the call on a browser or a video app.

Abstract: The invention relates to a ranging system for measuring the distance between an interrogator and a transponder. The transponder includes: a signal receiver for receiving a challenge signal from an interrogator; a signal processor for processing the challenge signal and generating a response signal in response to the challenge signal; a buffer for storing the response signal generated by the signal processor; and a signal transmitter for sending the response signal stored in the buffer when the signal processor receives a ranging signal from the interrogator, wherein a time interval between the challenge signal and the ranging signal is known to both transponder and the interrogator.

Abstract: A wireless switch or sensor is provided that includes a radio frequency (RF) transponder including a narrowband receiver operable to generate power from a received narrowband RF signal and an ultra wideband (UWB) transmitter operable to transmit UWB pulses using the generated power.

Abstract: An ultra low power, low complexity, low collision, deterministic modulation method that also works as a massive medium access mechanism for communication systems is based on positioning data in a communication resource space, such as time and frequency, such that the position of a symbol in that space determines its value and its access to the medium. The number base of the symbol is determined by the size of the subset of the resource space it is positioning itself in and, thereby, a few sparsely located symbols can convey a large value, while the remainder of the space can be simultaneously and massively used by other sparsely resource using members of the network.

Abstract: An asymmetric bandwidth communication system enables wireless communication between interrogators/readers and transponders/tags. A transponder transmits TDCIR (Time Domain Carrierless Impulse Radio) signals in the uplink direction and receives non-TDCIR signals, such as electromagnetic continuous waves, in the downlink direction. The transponder may receive partial or whole power from non-TDCIR signals. The TDCIR utilizes electromagnetic impulses with short duration and ultra wide bandwidth. It offers high data rate reliable communication at low power and design complexity. It also demonstrates resilience against path fading, selective absorption and reflection by physical matters and excellent location determination capabilities.

Abstract: A method and apparatus to overcome fundamental shortcomings in narrow band as well as wide band RFID solutions through offering a hybrid solution that utilizes benefits of narrow band in the downlink direction with the benefits of ultra wide band in the uplink. The invention encompasses a multitude of methods, including an approach to increase the ability to capture electromagnetic energy from the reader.
