This utility model discloses a multifunctional dual-channel timer, including a timer housing. On the front of the housing are mounted a first start button, a first audible and visual alarm, a first timer, a power switch, a second timer, a second audible and visual alarm, and a second start button. On one side of the housing are a power cord and a foot switch. The power cord, starting from the positive terminal, connects to the power switch and then connects to two parallel circuits. The first circuit connects to the first timer and then to the first audible and visual alarm via the first start button; the second circuit connects to the second timer and then to the second audible and visual alarm via the second start button. The foot switch is connected in parallel with both the first and second start buttons. The two timers disclosed in this utility model can operate independently, have personalized adjustment methods, have a simple structure, reliable operation, and are convenient and quick to operate, helping laboratories to quickly complete various tasks and improve work efficiency.

The utility model discloses a novel light wake -up alarm clock, including circular casing, base, time display module, ring lamp group, control button, speaker, light sensor, sound sensor and MCU controller, the circular casing is supported at the desktop through the base, the ring lamp group includes ring lamp box, wake -up LED and lighting LED, the ring lamp box is located the outer peripheral side of time display module and is located in the ring inlay groove, and the top surface height of ring lamp box is higher than the screen surface height of time display module, the top surface and inner circular surface of ring lamp box are arranged as upper light -transmitting panel and side light -transmitting panel respectively, the wake -up LED and lighting LED include several groups and are alternately arranged in the ring lamp box along the circumferential direction, the wake -up LED is fixed in the outer circular surface of ring lamp box and its light ray irradiates to side light -transmitting panel direction, and the lighting LED is fixed in the bottom surface of ring lamp box and its light ray irradiates to upper light -transmitting panel direction.

A controller of a bed is configured to receive one or more different types of sleep data, determine a sleep regularity factor for the user and a chronotype of the user, access, a machine learning model trained to determine a sleep onset time for the user, the machine learning model being trained based on (i) the one or more different types of sleep data including data that is representative of historic sleep times and historic wake time for the user, (ii) the sleep regularity factor of the user, and (iii) the chronotype of the user, determine e, based on an output of the machine learning model, a sleep onset time for the user, determine a target time to communicate a bedtime reminder notification to the user, and responsive to determining a target time to communicate a bedtime reminder notification to the user, communicate the bedtime reminder notification to the user.
