Abstract: A transmission interface between at least a first module and a second module is proposed. The transmission interface includes at least two physical transmission mediums. Each physical transmission medium is arranged to carry a multiplexed signal in which at least two signals are integrated. The at least two physical transmission mediums include a first physical transmission medium arranged to carry a first multiplexed signal including a first IF signal and a reference clock signal. The first IF signal and the reference clock signal are at different frequencies.

Abstract: An ergonomic dual-purpose pillow for back sleeping and side sleeping includes breathable pores and elastic support columns spaced from one another and disposed at the middle of the thickness of the pillow. The quantity, width, arrangement density or height of each breathable pore and/or elastic support column can be adjusted to let the supporting force fed back by a central support section of the pillow be smaller than that of the two side support sections of the pillow, so as to overcome the central recession of the conventional pillow that is likely to cause the head to slip off and leads to sleep problems.

Abstract: Disclosed is a health management system combined with a smart bed set. Unlike conventional hospital beds used for medical treatments or medical beds used for examining patients, the system of this disclosure breaks through the limitations that patients have to go to hospitals for physical examination and reduces spaces. This system detects and accumulates physiological data during our sleeping time for a long time and analyzes the physiological data to assist an early discovery of potential diseases, and the analyzed information is provided for the personal health management of individuals or the reference for medical professionals.

Abstract: A system and a method for adjusting a bed are disclosed. The bed is preset with a plurality of sets of adjustment parameters. An external muscle strength/pressure detection device or method is used to select at least two sets of the adjustment parameters suitable for the user. The corresponding sleep parameters are detected when the user sleeps, and the user-specific adjustment parameters are quickly selected and sent back to the bed for adjustment. Through the method, there is no need for the bed to provide pressure sensors.

Abstract: A flying machine capable of blocking light autonomously includes a machine body with a flight direction control module, a light sensor for detecting a sunshine angle, a position sensor for detecting the position of a moving object, and a flight movement adjuster to control the machine body to autonomously fly to a position linearly aligned with the sunlight and the moving object, so that the flying machine blocks between the sunlight and the moving object.

Abstract: A light emitting diode driving device and light system are provided. The light emitting diode driving device drives a light source by a received alternating current voltage. The light emitting diode driving device includes a rectifier, a feedback unit, a protection unit, a switch unit, a timing unit, and a control unit. The rectifier is electrically coupled to an alternating current voltage source and the light source for providing the alternating current voltage to the light source. The feedback unit is used to detect a loading state and generate a feedback signal according the loading state for outputting the feedback signal. The protection unit is used to receive the feedback signal and compare the feedback signal with a reference voltage built in the protection unit for outputting a switch signal. The switch unit is used to receive the switch signal and connect or disconnect the alternating current voltage source and the light source.
