A processor-based personal electronic device (such as a smartphone) is programmed to automatically respond to data sent by various sensors from which the user's activity may be inferred. One or more alarms on the device may be temporarily disabled when sensor data indicates that the user is asleep. One or more of the sensors may be worn by the user and remote from the device. A wireless communication link may be used by the device to obtain remote sensor data. Data from on-board sensors in the device—such as motion sensors, location sensors, ambient light sensors, and the like—may also be used to deduce the user's current activity. User data (such as calendar entries) may also be used to determine likely user activity and set alarms accordingly. Biometric data from a second, nearby person may also be used to automatically select certain alarm modes on a first person's device.

An organic light-emitting diode comprising an organic layer sequence, a radiation exit area and an encapsulation. The organic layer sequence comprises at least one radiation-emitting region which generates electromagnetic radiation in the spectral range from infrared radiation to UV radiation during operation. The radiation exit area is structured, so that the electromagnetic radiation has a directional emission profile. The encapsulation forms a seal of the organic layer sequence against environmental influences.

A device comprising an organic light-emitting diode comprising an organic layer sequence, a radiation exit area and an encapsulation, wherein the organic layer sequence comprises at least one radiation-emitting region which generates electromagnetic radiation in the spectral range from infrared radiation to UV radiation during operation, and wherein the encapsulation forms a seal of the organic layer sequence against environmental influences, at least one touch-sensitive operating element, wherein the at least one touch-sensitive operating element comprises at least one touch sensor, wherein the device is flexible.

A haptic device for an electronic device includes an actuation member formed from a shape-memory alloy (SMA) material that changes shape (e.g., expands or contracts) in response to an applied electrical current. In some cases, the haptic devices described herein also include a restoration mechanism that restores the actuation member to its original shape or to a similar shape. The change in the shape of the actuation member and the restoration of the shape of the actuation member may produce a haptic output at the electronic device.

A method of implementing an alarm clock, an electronic terminal and a system, where the method is applied to an electronic terminal, and includes obtaining a use end time of the electronic terminal, obtaining an alarm time of the electronic terminal, determining a time difference from the use end time to the alarm time, and determining an alarm manner of the electronic terminal according to the time difference, thereby increasing flexibility of an alarm manner of an alarm clock.

Organic light-emitting diodes as well as luminaires with such organic light-emitting diodes are specified. The luminaires may in particular be the following apparatuses, or the luminaires are part of existing apparatuses: alarm, shower cubicle, shower head, solar protection, rain protection, lamp, bed, signalling light, changing cubicle, vision protection, housing, emergency lighting, mirror, slabs, ceiling lights, radiator cladding, blinds, noise protection, umbrella, warning light.

A control method includes acquiring time information including a wake-up set time; acquiring a sleep state of a sleeper who is stimulated by a stimulation device; determining a change of the sleep state; causing the stimulation device to start increasing a stimulus which urges the sleeper to awake at a control start time as time before the wake-up set time by a predetermined time period; and controlling a change amount of the stimulus based on the change of the sleep state with the stimulus.

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).
