Abstract: Wireless communication systems and methods are provided for receiving user inputs as request to change the state of a wireless communication link between first and second wireless devices. A device, according to one implementation, includes a casing and an internal sensor arranged within the casing. The internal sensor is configured to electrically receive user input that is unrelated to manipulation of user-actuated mechanical components moveable with respect to the casing. The device further includes a decoding device configured to decode the user input as a request to change the state of a wireless communication link with a secondary device.

Abstract: Control systems and methods are provided that utilize a device, which can be worn by a user, to enable the user to enter control commands for causing a controller to control one or more electronic devices in a local network, such as a Wi-Fi system. A local control system, according to one implementation, includes a smart ring configured to obtain movement information related to one or more movements of the smart ring while a user is wearing the smart ring. The local control system also includes a controller device configured to communicate with the smart ring using Bluetooth or Wi-Fi signals. Characteristics of the movement information can be translated in order to obtain one or more control commands. The controller device is configured to control one or more aspects of one or more electronic devices based on the one or more control commands.

Abstract: A smart ring includes a battery, memory, processing circuitry, a plurality of sensors, a plurality of antennas, and a battery, each coupled to one another and all enclosed in a casing, wherein the processing circuitry is configured to conserve the battery by any of sending data to the cloud service when an application is open on the user device, sending data to the cloud service when a threshold is crossed, waking up processing or communicating when there is a change in motion detected by the accelerometer.

Abstract: A parallel platform tracking control apparatus and method using a visual device as a sensor are disclosed. The apparatus comprises a parallel platform body, a CCD camera (11), a lens (6), a camera light source (9), a computer (11), a Dspace semi-physical simulation controller, an ultrasonic motor driver and the like. The parallel platform comprises an ultrasonic linear motor (1), a linear grating encoder (5), a driven rod (2), a moving platform (3), a stationary platform (4) and the like. The CCD camera photographs the moving platform in a perpendicular and opposite manner, and the photographed images are subjected to an image processing algorithm to measure the position of the corresponding marker on the moving platform, which is not only applicable to measurement, but also implements real-time feedback of the termination position of the moving platform, such that a full closed-loop system is constituted. In this way, the parallel platform is precisely positioned.
