Abstract: A wireless roaming method and related system are provided. The method is applicable to an access control device and includes: determining a moving direction of a mobile device that is in a first connection connecting with a first access point; establishing, by a second access point and in response to a determination that the moving direction meets a preset condition, a second connection connecting the mobile device with the second access point, and disconnecting, by the first access point, the first connection. The first access point and the second access point are both connected to the access control device, and have a same static address or a same Identity Resolving Key. This method allows the mobile device to securely and seamlessly roam within the coverage areas of different access points.

Abstract: Various data (e.g., audio) relay devices and methods are disclosed. An exemplary data relay device may comprise a first chip configured to wirelessly connect to one or more physical sink devices, and a second chip. The second chip may be configured to create one or more virtual sink devices configured to be wirelessly detectable by one or more physical source devices, in response to the one or more physical source devices wirelessly connecting to the second chip, obtain data from the one or more physical source devices, and transmit the data to the first chip, causing the first chip to relay the data to the one or more physical sink devices.

Abstract: A device for supporting wireless communication is provided. The device may comprise a first Bluetooth chip for communicating with a Bluetooth device and a second Bluetooth chip for communicating with a client device. The second Bluetooth chip may be configured to receive advertising data of the Bluetooth device from the first Bluetooth chip and broadcast advertising data including the received advertising data of the Bluetooth device. The first Bluetooth chip and the second Bluetooth chip may be configured to establish communication links between the client device and the second Bluetooth chip, between the second Bluetooth chip and the first Bluetooth chip, and between the first Bluetooth chip and the Bluetooth device.

Abstract: A device for supporting wireless communication is provided. The device includes a first Bluetooth transceiver for connecting to a Bluetooth device, a second Bluetooth transceiver for connecting to a client device, one or more processors, and a memory for storing instructions executable by the one or more processors. The one or more processors may be configured to scan for one or more available Bluetooth devices via the first Bluetooth transceiver, establish a first communication connection with the Bluetooth device via the first Bluetooth transceiver, establish a second communication connection with the client device via the second Bluetooth transceiver, receive data from the client device via the second communication connection, and forward the data to the Bluetooth device via the first communication connection.

Abstract: Devices, systems, and methods are disclosed for detecting falls and transmitting notifications. One embodiment includes a wearable device. The wearable device may include a first sensor configured to collect acceleration data, and at least one of a second sensor configured to collect pressure data or a third sensor configured to collect temperature data. The wearable device may also include an antenna and a processor. The wearable device may also include a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to receive the acceleration data and at least one of the pressure data or the temperature data, process the acceleration data and at least one of the pressure data or the temperature data, and control, when the processor determines that a person falls, the antenna to transmit a signal.
