Abstract: An optical transmission and reception carrier includes an optical fiber, an invisible light transmitter, an invisible light receiver, a visible light transmitter and a fiber optic connector. The invisible light transmitter is configured to emit a first invisible light toward the fiber optic connector and includes a first connection element. The invisible light receiver is configured to receive a second invisible light from the fiber optic connector and includes a second connection element. The visible light transmitter is configured to emit a visible light toward the fiber optic connector. One of the first connection element and the second connection element is a flexible flat cable.

Abstract: A lighting device includes a driver, a first light string, a second light string, a constant current controller and a pulse width modulation controller. The driver is configured to provide a DC driving current to a shunt node. The first light string is electrically coupled between the shunt node and a ground terminal, and the first light string is driven by a first pulsating direct current. The second light string and the constant current controller are electrically coupled in series between the shunt node and the ground terminal. The pulse width modulation controller is configured to provide a pulse signal to the constant current controller, and the constant current controller controls a pulse frequency of a second pulsating direct current supplied for the second light string according to the pulse signal.

Abstract: A method for providing demonstration information in a simulation environment and associated simulation system are provided. The method includes: controlling a head mounted display (HMD) device of the simulation system to present the simulation environment and allow a user of the simulation system to see the simulation environment when wearing the HMD device on the user's head; controlling the HMD device to display a first controller in the simulation environment, to allow the user to interact with the simulation environment; controlling the HMD device to display a menu including a plurality of items, to allow the user to select an item of the plurality of items with aid of the first controller; and controlling the HMD device to display a predetermined space associated to a product corresponding to the item, wherein the predetermined space is different from default space of the simulation environment, and includes demonstration information of the product.
