Wearable communication devices, e.g. implemented in a watch, using short range communication e.g. to a cell phone allow a user to talk and listen, place and answer calls, send and receive text messages, initiate voice commands to mobile search for information and find locations, and be notified of incoming calls, texts, and events, all while a phone is nearby but not visible. Notification is performed with vibration, an LED light or OLED text display of incoming calls, texts, and calendar events. It allows communicating hands-free. The watches can be directly connected to a smartphone allowing using the watch as “remote control” for home appliances or any other devices via voice and buttons. Motion sensors such as accelerometer, magnetometer and gyroscope, together with audio generation device can be used for gaming applications.

A method of operating a first electronic device for improving call quality is provided. The method includes the operations of transmitting call data received through a first call between the first electronic device and a third electronic device to a second electronic device, using short-range wireless communication connected with the second electronic device, if a communication abnormality of the short-range wireless communication takes place, connecting a second call between the first electronic device and the second electronic device, generating a third call by merging the first call and the second call, and releasing a call connection of the first electronic device from the third call.

Methods and apparatuses for communications between a wearable device, a headset that can be attached to and detached from the wearable device, and a communications device. The wearable device detects when a user detaches the headset and establishes a Bluetooth connection between the headset and the wearable device or between the headset and another communications device.

A stationary exercise device comprises pedals mounted via cranks to opposite sides of a drive wheel; a flywheel with a magnetic rim coupled to the drive wheel; a brake with a motor and one or more permanent magnets mounted for movement relative to the magnetic rim; a measuring unit for measuring at least one of the drive force applied via the drive wheel and the related torque; a measuring device for measuring cadence; and a command module. The command module uses measurements from the measuring unit and the measuring device to calculate a performance parameter and compares the performance parameter against a predetermined performance profile. The command module also can control the motor to move the permanent magnets relative to the magnetic rim to adjust the braking force applied and thereby adjust the performance parameter to conform with the performance profile.

A document processing system and method includes a display, and an embedded controller that includes a BLUETOOTH low energy network interface that is configured for communications with mobile computing devices. When a mobile computing device of a user approaches to within a threshold distance of the document processing system, the user can be presented with directions to the document processing system or service related information about the document processing system. With the mobile computing device is within close proximity of the document processing system, the embedded controller sends the user interface of the document processing system to the mobile computing device for display to the user. The distance between the mobile computing device and the document processing system can be approximated using the received signal strength indicator (RSSI) of BLUETOOTH low energy communications received from the mobile computing device by the document processing system.

A mobile terminal and controlling method thereof are disclosed, by which image data of a counterpart having triggered an event can be displayed. The present invention may include a display unit configured to display information, a wireless communication unit configured to communicate with an external server that stores first image data and to communicate with a counterpart terminal, a memory to store a second image data, and a controller, in response to an event triggered by the counterpart terminal, to extract an image data related to a counterpart from one of the first image data and the second image data, and the controller to output the extracted image data on a portion of the display unit to notify an occurrence of the event.

A method of operating a display device includes displaying a first image of first content, wherein the first image includes a target object, receiving information on a second coordinate of the target object included in a second image of the first content from a second display device, wherein the second image is temporally later than the first image, acquiring an image tracking the target object from the second image based on the information on the second coordinate of the target object, and displaying the acquired image.

A technical data monitoring device for use with a wireless data monitoring network includes a wireless communications circuit, and at least one technical device/system. The technical data monitoring device establishes a wireless communication link with a programmable interface of a programmable cellular telephone. The device is also configured to send and/or receive wireless packet switched data transmissions, generate data and send data over the wireless communication link for processing by the programmable cellular telephone, and has an associated status condition. Data from the device is (1) sent to be processed and displayed by the programmable cellular telephone and/or (2) sent to be processed and forwarded by the programmable cellular telephone to an Internet website. The device forms part of the wireless data monitoring network in communication with the programmable cellular telephone. The technical device/system can be one of a number of sensors, devices, or systems.

Systems and methods for transitioning calls are presented. In one example, data is received associated with a connected wireless mobile phone call. The data may include identification data of a far end call participant. A user selection is received to initiate an outgoing call to the far end participant. The outgoing call is initiated over a wired connection to the far end participant.

A testing method for a smart wristband and a testing system thereof are provided. The Bluetooth function of the smart wristband is put into a sleep state through presetting of the system software before the test, and the testing method comprises the following steps of: carrying out electrical connection operations on the smart wristband under test during the test so that the Bluetooth function of the smart wristband is activated; completing pairing between the smart wristband and the testing apparatus, and synchronously displaying a corresponding function of the smart wristband on a screen of the testing apparatus so as to be tested, wherein the testing apparatus is a smartphone, and the testing of the corresponding function includes at least one of Bluetooth power testing, writing of the mainboard serial number, charging testing and motor vibration controlling.
