Patent number: 10089849Abstract: Embodiments of the disclosure relate to systems and methods for isolating a base station beacon and gas reading transmission channel(s) based on a single radio wireless gas detection system. A gas detector may communicate on a first channel (e.g. a beacon channel) constantly listening to the base station beacon information. At a pre-defined interval (e.g. every 60 seconds), the gas detector radio may switch to a second channel (e.g. a data channel) to transmit gas reading data as well as the base station information to a central server. Software on the server may complete a triangulation algorithm to determine the location of the gas detector, using information obtained by the detector from the beacons.Type: GrantFiled: March 12, 2015Date of Patent: October 2, 2018Assignee: Honeywell International Inc.Inventors: James Liu, Peter Hsi, Pengjun Zhao, Kai Ren, Xiaoxiong Li

Patent number: 10055971Abstract: Embodiments relate generally to systems and methods for communication between one or more personal protection equipment (PPE) devices, a mobile device, and a central monitoring station. Personnel may wear PPE devices for detection and communication. These portable devices may communicate wirelessly, over a wireless fidelity (Wi-Fi) network, via Bluetooth, or another wireless connection. Systems may include a smartphone application operable to receive and combine information from each of the PPE devices. The application may also display the information to the user. In some embodiments, the application may transfer the data to a cloud storage network via a cellular network. Additionally, the application may communicate the combined data from all of the PPE devices to the central monitoring station.Type: GrantFiled: November 27, 2015Date of Patent: August 21, 2018Assignee: Honeywell International Inc.Inventors: Gowrishankar M R, Anand Tyagaraj, Peter Hsi, Shashikant Gulaguli, James Liu, Patrick Gonia, Saurabh Shah, Praveen Sharma, Tarun Kumar
