A method of an optical sensor apparatus which is to be used with a controlling device arranged for controlling an object having a long shape and flexible form of a material, includes: using a light emitting circuit to generate and output a light ray to a surface of a portion of the object; sensing the light ray reflected from the surface for multiple times to generate multiple images; detecting at least one motion image in the generated multiple images; and, determining a motion, an offset, or a rotation angle of the object, which is controlled by the thread controlling device, according to the detected at least one motion image.

An imaging device includes a lens that guides, to an imaging element, light reflected from a subject, a wearing tool for wearing at least the lens on a wearing target, and at least one processor. The processor determines whether a first condition based on a positional relationship of the lens with respect to the wearing target is satisfied, determines whether a second condition that includes a condition based on the positional relationship of the lens with respect to the wearing target is satisfied, the second condition differing from the first condition, and makes an imaging parameter of at least one of the imaging element or the lens for when the first condition is satisfied and for when the second condition is satisfied different from each other.

A wearable electronic device and a display switching method thereof, includes turning on a first display apparatus of the wearable electronic device to make the first display apparatus in a working state; rendering a first image in a first display region of the first display apparatus with a first display effect by the first display apparatus; obtaining first parameter information related to an input operation, by a sensing apparatus of the wearable electronic device; judging whether a second display apparatus of the wearable electronic device is to be turned on or not, according to the sensing parameter; and rendering a second image in a second display region of the second display apparatus with a second display effect by the second display apparatus, when the second display apparatus is to be turned on to make the second display apparatus in the working state.

A device for monitoring athletic performance of a user has a wristband configured to be worn by the user. An electronic module is removably attached to the wristband. The electronic module has a controller and a screen and a plurality of user inputs operably associated with the controller.

In one embodiment, an apparatus includes a wearable computing device that includes one or more processors and a memory. The memory is coupled to the processors and includes instructions executable by the processors. When executing the instructions, the processors determine whether an application is running on the wearable computing device. The application controls one or more functions of a remote computing device. The processors determine to delegate a task associated with the application; delegate the task to be processed by a local computing device; and receive from the local computing device results from processing the delegated task.

A system is provided for dispensing a fluid. The system has a housing having a fixation means to a user and an orientation element; the cartridge formed so as to be held in a given orientation by the orientation element with respect to the housing; and control means to activate the cartridge to eject a fluid. In one aspect, the system is a emergency rescue fluid(s) transdermal delivery system which includes a removable, single use emergency rescue fluid(s) dispensing cartridge, a wearable device into which the emergency rescue fluid(s) dispensing cartridge uniquely, matingly and removably inserts. The system includes a communication pathway between the wearable device and at least one other cloud network node, and/or at least one communication pathway between the wearable device and at least one GPS network node. In another aspect, the system dispenses a perfume or other fragrance.

Provided is a method for unlocking by use of a knob. The method is applied to an electronic device provided with an operation knob. The method includes the following steps: detecting (1) an action of the operation knob in a screen locked state in real time; and starting (2) an unlocking program in response to rotation of the operation knob: calculating the rotational circumferential distance of the operation knob along the current rotational direction, determining whether the rotational circumferential distance of the operation knob reaches a preset circumferential distance, controlling the electronic device to unlock in response to the rotational circumferential distance of the operation knob reaching the preset circumferential distance, and unlocking failed and returning to step (1) in response to the rotational circumferential distance of the operation knob not reaching the preset circumferential distance.

Disclosed is a wrist watch embedded with a wireless control module that generates control commands in accordance with user's motional operations. The control commands are provided wirelessly to a particular intelligent mobile device, to control the functions of the intelligent mobile device. The motional operations comprise one or more of a shifting/swinging, rotation and knocking operation, or their combinations.
