Abstract: A charging management apparatus, a charging apparatus, and a charging management method are disclosed. The charging management apparatus includes: a circuit board; a wireless communication module, connected to the circuit board and used to perform wireless communication with an intelligent terminal; and a current sensing module and/or a voltage sensing module, connected to the circuit board. The current sensing module is used to sense a charging current, and the voltage sensing module is used to sense a charging voltage. The charging apparatus includes the charging management module. The charging management method includes acquiring parameters of a charging apparatus and parameters of an intelligent terminal to be charged and correspondingly displaying the parameters; and issuing a prompt when a battery power of the charging apparatus and/or the intelligent terminal reaches a preset threshold.

Abstract: A mobile device, particularly a wireless headset, includes a cord to which an earpiece is fixed and a module having a spring-actuated retractor reel into which the cord is retracted for storage. A fastener on the module makes the device wearable. A rotary encoder generates a position data output according to the rotational position of the reel, and a controller receives the position data output from the sensor, and, in response, controls a function such as placing the device in an on-hook or off-hook state.
