Abstract: The present invention introduces a method for guiding an optimal stretching time to a user who has a wearable electronic device and a mobile communication device for measuring a set of measurement data comprising activity data of the user. The determination logic, implemented e.g. in a form of a server, takes age and gender into account, and determines a stretching index based on the activity of the user. The optimal stretching time may be alerted, with stretching guidance, to the user. Sleep can be taken into account as well. The system measures whether the actual stretching is done. Sleep is further analyzed, so the effect of the stretching can be monitored and this information can be given back to the user via the mobile communication device. Stretching guides can be updated as well. The wearable electronic device can be a ring device.

Abstract: The present invention discusses a system and method for defining an optimal wakeup time with an alarm, which method takes into consideration at least two persons. Sleep monitoring devices, such as health rings or bed sensors, measure parameters of the sleepers, and a server determines sleeping phases from the measurement results.

The analysis combines at least two persons and sets rules so that no-one is preferably woken from a deep sleep phase. The determined alarm time is a given time period before the final alarm deadline. An optimal alarm time is calculated in the server, and the alarm is triggered in a mobile device, through the wearable ring, or by another alarming device or means.

Abstract: The present invention introduces an arrangement for enhancing the performance of an electronic circuit comprising a phototransistor (Q). Either a common-collector or a common-emitter connected phototransistor (Q) has a main resistor (RL), and at least one external bias resistors (RL2, RL3, RL4), each in parallel to one another. The microcontroller may directly control the voltage outputs or act via respective switches (S1, S2) regarding each respective resistor. When the electronic circuit with the phototransistor (Q) is switched on, at least one of the external bias resistors (RL2, RL3, RL4) are switched on. The voltage output rise time is short, and when the bias has been set, the external bias resistor(s) are disconnected functionally. This means that during the actual measurement with the electric circuit, only the main resistor (RL) is used in the connection.
