  • Patent number: 11930568
    Abstract: A controller for controlling a light source module including a first LED array and a second LED array includes a first driving terminal and a second driving terminal. The controller is operable for turning on a switch between a power converter and the first LED array by the first driving terminal to deliver electric power from the power converter to the first LED array in a first sequence of discrete time slots, and for turning on a second switch between the power converter and the second LED array by the second driving terminal to deliver electric power from the power converter to the second LED array in a second sequence of discrete time slots, where the first sequence of discrete time slots and the second sequence of discrete time slots are mutually exclusive.

  • Publication number: 20230104307
    Abstract: A medical apparatus includes an inflow tube having a first conduit having a first inner diameter. An outflow tube has a second conduit having a second inner diameter. An intermediate tube has a first end and a second end, the first end connected to the inflow tube and the second end connected to the outflow tube. The intermediate tube has a third inner diameter, the third inner diameter being larger than the first inner diameter and the second inner diameter. The intermediate tube defines a flow path. The flow path includes a first flow path configured to direct a liquid flowing along the flow path in a first direction, and a second flow path configured to direct the liquid flowing along the flow path in a second direction. The first direction is opposite to the second direction.

  • Patent number: 11032881
    Abstract: A controller for controlling a light source module including a first LED array and a second LED array includes a power input terminal, a first power output terminal and a second power output terminal. The power input terminal is operable for receiving electric power from a power converter. The first power terminal is coupled to the first LED array, and the second power output terminal is coupled to the second LED array. The controller is operable for delivering the electric power to the first LED array via the first power output terminal in a first sequence of discrete time slots, and for delivering the electric power to the second LED array via the second power output terminal in a second sequence of discrete time slots. The first sequence of discrete time slots and the second sequence of discrete time slots are mutually exclusive.

  • Patent number: 4970042
    Abstract: A synthetic fiber having an uneven surface structure consisting of wrinkles having ridges and recesses of the surface of the fiber and not presenting specular luster, which may be used, for example, as artificial hair for wigs, can be produced easily and stably by melt-spinning a starting synthetic resin such as nylon and passing the spun monofilament through a cooling bath at a temperature not lower than 30.degree. C. for a period of time sufficient for developing wrinkles in its surface. Inclusion of a pigment such as carbon black in an appropriate amount in the starting material is effective in providing dense distribution of wrinkles.
