Abstract: In an example in accordance with the present disclosure, a compute device is described. The compute device includes a host controller to 1) receive identification data of peripheral devices coupled to a computing dock and 2) compare the identification data with values stored in a database. A stored value indicates a combination of peripheral devices previously coupled to the computing dock. The compute device also includes a device connection controller to, responsive to the identification data matching a stored value, retrieve operational data for the peripheral devices from the database. The device connection controller is also to connect the compute device with the peripheral devices based on operational data retrieved from the database.

Abstract: In some examples a computing device, comprising a battery, a processing resource and a memory resource storing non-transitory machine-readable instructions can cause the processing resource to determine a battery charge capacity of the battery, in response to the battery charge capacity being less than a threshold capacity, cause the battery to charge, and in response to the battery charge capacity being greater than the threshold capacity, compare the battery charge capacity of the computing device with a different battery charge capacity associated with a different computing device, and based on the comparison, cause a charge determination event to occur.

Abstract: An electronic cigarette able to test for alcohol on the breath and transmit such data by wire or wirelessly to another device for comparison purposes and for display includes a liquid module, an atomizer, an alcohol testing module, and a microprocessor. Tobacco tar from the liquid module is converted by the atomizer into smoke. The alcohol testing module detects user's alcohol concentration on the breath when the electronic cigarette is turned on. The microprocessor records all data and establishes wireless communication with a portable electronic device and/or a server. The operating data of the atomizer and the alcohol concentration data can be transmitted to the portable electronic device and/or the server for being analyzed and storage.

Abstract: A smart module for a smart shoe includes a second cover, a first cover, an antenna, a circuit board, and a power supply unit. The second cover cooperates with the first cover to form a housing for receiving the antenna, the circuit board, and the power supply unit. The antenna and the power supply unit are electrically connected to the circuit board. The power supply unit supplies power to the circuit board and the antenna. The first cover includes at least one positioning member. The antenna includes at least one positioning hole. The circuit board includes at least one positioning hole. The positioning holes in the antenna and the circuit board align with and receive the positioning member of the first cover to ensure that the antenna and the circuit board are mounted at appropriate locations in the first cover. Therefore, the smart module facilitates easy assembly.
