Patent number: 11960288Abstract: An autonomous mobile device (AMD) moves around a physical space while performing tasks. The AMD may have sensors with fields of view (FOVs) that are forward-facing. As the AMD moves forward, a safe region is determined based on data from those forward-facing sensors. The safe region describes a geographical area clear of obstacles during recent travel. Before moving outside of the current FOV, the AMD determines whether a move outside of the current FOV keeps the AMD within the safe region. For example, if a path that is outside the current FOV would result in the AMD moving outside the safe region, the AMD modifies the path until poses associated with the path result in the AMD staying within the safe region. The resulting safe path may then be used by the AMD to safely move outside the current FOV.Type: GrantFiled: September 8, 2021Date of Patent: April 16, 2024Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Yue Hu, Jong Jin Park, Daimian Wang, Roopesh Athipatla Pattabhi, Jingyu Qiao, Changsheng Shen

Publication number: 20170142478Abstract: The embodiment of the present disclosure provides a method and a device for detecting a shielded WiHD data projection channel. The method comprises: establishing a WiHD data projection channel between a mobile terminal and a WiHD data receiver; transmitting a verification message to the WiHD data receiver through the WiHD data projection channel; determining whether a response message is received or not; if not, generating an event that the state of the WiHD data projection channel is changed; displaying the prompting indicating that the WiHD data projection channel is shielded according to the event. According to the present disclosure, when the response message is not received, the situation means that the WiHD data projection channel is shielded, and then the prompting of shielding may be displayed to prompt a user to adjust the position of the mobile terminal so as to eliminate shielding.Type: ApplicationFiled: August 26, 2016Publication date: May 18, 2017Inventors: Yaqiong LIU, Jingyu HU
