Abstract: A signal transmitting element is used to solve the problem that an additional surgery is required to remove the conventional vascular monitoring element after completing the detecting task. The signal transmitting element comprises a body made of a specific biodegradable material. The body includes a signal sensing portion including a structure configured to sense a blood flow information of a blood vessel surrounded and contacted by the body, thereby generating a blood vessel signal; and a signal transmitting portion coupled with the signal sensing portion for receiving the blood vessel signal and including a specific structure configured to convert the blood vessel signal into a transmission signal.

Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: The present invention is a control method of color temperature and luminance for an LED device and a control system thereof. The control method has the following steps: executing a cold-start motion; determining whether a warm-start motion is executed during a preset time; if yes, adjusting the color temperature of the LED device, and determining whether the warm-start motion is executed again during the preset time; if not, adjusting the luminance of the LED device, and determining whether the warm-start motion is executed again. A user can adjust the color temperature and the luminance of the LED device by turning off and on a switch of the control system.

Abstract: A dimming system is composed of a dimmer having switchable power modes and at least one lighting device. When the dimmer is in a non-dimming bypass mode, an input power is directly transmitted to the at least one lighting device with the dimmer being bypassed so that the circuit in the dimmer consumes no power. When the dimmer is in a dimming mode, an output selector of the dimmer outputs a dimming output power having a dimming command therein to each one of the at least one lighting device for each lighting device to decode the dimming command embedded in the dimming output power and perform a dimming operation according to the dimming command. As the dimming operation lasts briefly, the power consumed by the dimmer is extremely small. Accordingly, no heat dissipation issue arises and the present invention is applicable to all sorts of high power lighting devices.
