Abstract: Aspects of the present disclosure describe a battery-free touch sensing user interface (UI) for Internet of Things (IoT) and other smart spaces employing Radio Frequency Identification (RFID) readers and tags that we call RIO. With RIO, any surface may be a touch-aware surface by attaching RFID tag(s) thereto. RIO advantageously supports custom-designed RFID tags and therefore facilitates customized UIs to be easily deployed in a real-world environment. RIO employs impedance tracking that results from a human finger—or other appendage—touching a surface of an RFID tag, thereby changing a characteristic impedance of the RFID tag antenna. This change manifests as a change in the phase of the RFID backscattered signal and is advantageously used by RIO to track fine-grained touch movement over the RFID tag. Disclosed further are multi-tag environments in which RIO operates and demonstrations including continuous tracking of finger movement during a swipe to within 3 mm of its actual position.

Abstract: A method of charging a light bulb is disclosed. A processor within the light bulb detects a state-of-charge of the battery and if it is below a predetermined dynamic battery state-of-charge threshold then the transceiver sends a wireless signal from the light bulb to a remote light switch with instructions to supply power to the light bulb. The predetermined dynamic battery state-of-charge threshold may be determined based on historical light use data during an on-peak energy time period. The predetermined dynamic threshold allows a battery in the light bulb to supply energy to the light bulb during on-peak hours and recharge during off-peak hours.

Abstract: In a retransmission control method and device which can suppress or expedite a retransmission of user data depending on a processing congestion status or the like on a receiving side, a user equipment on a data receiving side transmits to a radio network control device on a data transmitting side, when redundantly receiving an ACK request included in same user data, control data for extending a timeout period of a polling timer which is a retransmission time interval of user data for a subsequent ACK request by e.g. 10 ms. The radio network control device having received the control data extends the timeout period based on the control data. Alternatively, the radio network control device reduces, when receiving an ACK response from the user equipment within the timeout period, a timeout period of user data for a subsequent ACK request to less than the timeout period presently set.

The other ECUs perform similar operations to those of the ECUs, while the other distribution apparatuses perform similar operations to those of the distribution apparatus. Therefore, each of the distribution apparatuses can recognize the status of all the ECUs.
