Abstract: Short-range and long-range operating methods for hospitality accommodation automation and control using APP, webpage, smartphone, RFID-to-Bluetooth selective adapter, relay controller together with RFID door lock is disclosed, where unlocking RFID door lock requires just pressing a button, various power outlets, lighting levels, HVAC settings, and tv settings can be controlled by smartphone. A gateway device with internet connectivity allows remote unlock or lock of doorlock, sending notifications of door unlock events back to a cloud server, and remotely control electrical or electronic devices under short-range or long-range modes. Detection methods for determining whether any occupant remains inside the room is also included. Current sensor is used for assess electric power consumption rate.

Abstract: RFID-to-Bluetooth selective adapter with multiple RFID integrated chips mounted on RFID elevator controller, having customized RFID transponders, a bluetooth module, and an extended I/O connector is disclosed. Customized RFID transponders include RFID Integrated chips, RFID sensor coils, and a SPNT switch. Extended I/O connector is configured to allow connection of customized RFID transponders by coupling to SPNT switches. Bluetooth module instructs which one of SPNT switches is to be opened or closed, which then connects one RFID sensor coil with one corresponding RFID Integrated chip, while other RFID sensor coils and remaining RFID Integrated chips are disconnected. Selection criteria of chosen RFID IC by Bluetooth module is in accordance with preconfigured allocated access right given to each user by an administrator and is programmed on flash memory, EEprom memory of Bluetooth module, in APP, or on cloud authentication server. More than one customized RFID transponder can be chained together.

Abstract: Method and system for turning on an IoT device directly in a contactless manner using a mobile phone with a camera light source and an app is disclosed. A photo sensor unit is provided on top of the IoT device for converting the incident light from mobile phone into authorized and authenticated power-on switching command to the IoT device. The photo sensor unit can be a first photosensitive circuit, a second photosensitive circuit, or a third photosensitive circuit, which includes a photodiode, a photo resistor, and an amorphous silicon solar cell, respectively. The photo sensor unit is coupled to a power-on circuit of the IoT device, and used for detecting an intensity of incident light and assessing whether a voltage difference produced by the incident light exceeds a power-up voltage difference threshold value, and if so, awaking the IoT device to be power-on, otherwise, maintaining the IoT device to stay powered off.

Abstract: The present invention discloses a positioning system based on Received Signal Strength having an antenna device with a directional patch antenna with circular polarization, and an installation method thereof. By having a circular polarization, being directional and of a patch design, the directional patch antenna can mitigate signal strength discrepancies caused by devices located at different angles, and signal strength interference due to presence of multi-paths, and front-end antenna radiation pattern and input impedance caused by ambient environment of the antenna device and other material compositions. Beacons are preferably installed on the ceiling, which can improve the line-of-sight (LOS) opportunities between the positioning devices and tracked objects.

Abstract: A RFID-to-Bluetooth selective adapter which includes a customized RFID transponder with an on/off switch, a RFID sensor coil, and a Bluetooth module with an EEPROM memory is disclosed. The RFID-to-Bluetooth selective adapter can be attached to a RFID doorlock to operate in both RFID mode and Bluetooth modes without interference therebetween, so as to use by RFID tags or smartphones, respectively. The RFID reader equipped device can be a RFID smart doorlock; a door is configured with the RFID smart doorlock and the RFID-to-Bluetooth selective adapter is mounted thereon, and the door can be opened and closed using the APP by the authorized user in real-time with or without internet connection. The RFID-to-Bluetooth selective adapter functions as a bridge between the RFID reader equipped device and smartphone operating under Bluetooth smart. In addition, the RFID-to-Bluetooth selective adapter possesses several security upgrade options.
