CPC Class H04N

The present application relates to the field of motors, and provides a motor, a gimbal and a mechanical are having the same. The motor includes a support, a circuit board installed on the support and including a coil circuit, a rotating shaft, and a permanent magnet. The support is installed on the rotating shaft. The permanent magnet is disposed adjacent to the coil circuit, and there is a gap between the permanent magnet and the coil circuit. The permanent magnet is of an axially magnetized structure. In the present application, the circuit board is adopted as a carrier of the coil circuit to replace an icon core in the traditional technology, thereby eliminating defects such as cogging torque, hysteresis, and eddy-current losses that are generated by an existing motor from the root. More over, the axial size of the motor and the weight and volume of the motor are reduced.

With a driving current as IDRV, with a reference voltage as VREF, and with a gain as k, a current detection circuit generates a detection voltage VS represented by VS=VREF+k×IDRV. An error amplifier amplifies a difference between the detection voltage VS and a control voltage that indicates a position of the VCM so as to generate an error voltage VERR. A first driver switches the driving current IDRV between a source current and a sink current with respect to one end of the coil according to the error voltage VERR. A second driver switches the driving current IDRV between a sink current and a source current with respect to the other end of the coil according to the error voltage VERR. The driving circuit allows an external circuit to set the level of the reference voltage VREF.

Optical network termination systems, devices and methods including an optical network terminal (ONT) having a processor in communication with an external optical fiber. The ONT processors further in communication with a wireless access point and at least one electrically conductive internal transport medium, both providing for the communication of telecommunication signals with devices located within a customer premises. The wireless access point and in certain instances the processor are back powered over the electrically conductive internal transport medium from AC power within the premises. In certain embodiments, the wireless access point communicates with devices within the premises over a distributed antenna.

A method, non-transitory computer readable medium and apparatus for providing a communications service in a communications network are disclosed. For example, the method monitors a conference call, detects a triggering event during the conference call registered for a particular user, wherein the particular user is not a participant in the conference call, and notifies the particular user of the triggering event.
