Disclosed is an electronic device including a rotation member that rotates in a first direction or a second direction, a memory configured to store a specific rotation pattern, and a controller configured to, if a rotation pattern of the rotation member between the first direction and the second direction matches with the specific rotation pattern, perform a functional operation corresponding to the specific rotation pattern.

Smart watches and associated systems and methods thereof for lock-screen management are disclosed. A smart watch includes a heart rate sensor, and a method for lock-screen management of the smart watch includes: reading, by the heart rate sensor, a heart rate; determining based on the heart rate whether the smart watch has been taken off by the user, and if yes, stopping the heart rate sensor from working and entering by the smart watch a password-lock-screen mode. Thus, using the method according to the present disclosure can improve the information security on the smart watch.

A watch-type mobile terminal including a display; a bezel forming a rim of the display and including a touch sensor; a crown; and a controller configured to display first content on the display, sense a rotation input on at least one of the crown and the bezel when the first content is displayed on the display, and display second content associated with the first content on the display in response to the rotation input.

A wearable apparatus, comprising: a mounting component (2), configured to hold a relationship between relative positions of the wearable apparatus and its user; a folding panel (1) mounted on the mounting component (2), the folding panel (1) including at least two display screens (11,12,13,14) interconnected at a joint where sensors are disposed; and a controller (60) signal connected with individual display screens (11,12,13,14) and the sensors (50) respectively, the controller (60) being configured to control corresponding display screens to turn on or turn off based on the state of the folding panel (1) detected by the sensors (50). The state of the folding panel in the wearable apparatus can be adjusted according to the needs of a user and thereby the usage needs of the user can be satisfied.

An electronic device, such as a watch, has a crown assembly having a shaft and a user-rotatable crown. The user-rotatable crown may include a conductive cap that is mechanically and electrically coupled to the shaft and functions as an electrode. The conductive cap may be coupled to the shaft using solder or another conductive attachment mechanism. The shaft may electrically couple the conductive cap to a processing unit of the electronic device. One or more additional electrodes may be positioned on the exterior surface of the electronic device. The conductive cap is operable to be contacted by a finger of a user of the electronic device while another electrode is positioned against skin of the user. The processing unit of the electronic device is operable to determine a biological parameter, such as an electrocardiogram, of the user based on voltages at the electrodes.

A communication apparatus comprises a communicator that receives a standard time from an external apparatus, a manipulation receiver that receives a time correction action from a user, and a controller that performs a timing processing for clocking time and a time correction processing for correcting the time clocked by the timing processing, on the basis of the standard time received by the communicator, or on the basis of the time correction action received by the manipulation receiver. The controller changes processing contents of the time correction processing until a prescribed time interval has elapsed, when the time clocked by the timing processing is corrected on the basis of the time correction action received by the manipulation receiver.

A push button device including a supporting member which is provided with a through hole and in which a recess section is provided outside the through hole, an operation member which includes a shaft section that is slidably inserted into the through hole, and a head section that is provided on an outer end of the shaft section and slidably fitted into the recess section, a first filter which is provided in the recess section and arranged at a position surrounded by an annular first groove section into which an outer circumferential convex section of the head section is fitted and the outer circumferential convex section, and a second filter which is provided in the head section and arranged at a position surrounded by an annular second groove section into which an inner circumferential convex section of the recess section is fitted and the inner circumferential convex section.

An electronic device, such as a watch, has a variable friction mechanism for providing variable frictional feedback as an input mechanism, such as a crown, is rotated. The variable frictional feedback may correspond to operational states, events, or other conditions at the electronic watch. The variable frictional feedback may be provided by changing a frictional force between the crown and the variable friction mechanism. The variable friction mechanism may include a friction element adapted to contact a shaft of the crown and an actuator adapted to change a frictional force between the friction element and the shaft.

A system and method to determine angular movement of an arbor integral with a crown of a watch, the arbor being rotatable on itself in a longitudinal direction. The system includes a rotating reflector mounted on the arbor, and two emitter/detector pairs disposed on either side of the reflector, each including a light source for illuminating the reflector, and a light detector for receiving the light reflected on the reflector and for generating an electrical signal representative of the reflected light. A processor processes the electrical signals, and determines a parameter relating to the angular movement of the arbor. The rotating reflector is a cylinder of revolution and light absorption points are made on the circumference of an external cylindrical surface. When the reflector rotates in a regular manner and in the same direction of rotation, the representative electrical signal generated by each detector has a sinusoidal shape.

A pulse wave signal is registered and an occurrence of human limb movements detected during sleep using a pulse wave sensor and an accelerometer. The values of RR intervals and respiratory rate are measured at preset time intervals Δt.sub.i based on pulse wave signal. Mean P.sub.1, minimal P.sub.2, and maximal P.sub.3 values of RR intervals, the standard deviation of RR intervals P.sub.4, average respiratory rate P.sub.5 and average number of limb movements P.sub.6 are determined based on the above measured values. Function value F(Δt.sub.i) is determined thereafter as:
F(Δt.sub.i)=−K.sub.1P.sub.1−K.sub.2P.sub.2−K.sub.3P.sub.3+K.sub.4P.sub.4+K.sub.5P.sub.5+K.sub.6P.sub.6,
where K.sub.1-K.sub.6 are weight coefficients characterizing the contribution of the corresponding parameter to function value F(Δt.sub.i); whereat the onset and termination of sleep phase favorable to awakening is determined by increments of function F(Δt.sub.i).
