  • Publication number: 20240068030
    Abstract: A honeycomb tube with a planar frame defining a fluidic path between a first planar surface and a second planar surface. A fluidic interface is located at one end of the planar frame. The fluidic interface has a fluidic inlet and fluidic outlet. The fluidic path further includes a well chamber having a well-substrate with a plurality of wells. The well chamber is arranged in the planar frame between the first or second surface and the well-substrate. The well chamber is in fluidic communication between the pre-amplification chamber and the fluidic outlet.

  • Patent number: 8929107
    Abstract: A surge protection module is disclosed. An example surge protection module includes a first terminal coupled to a first output terminal of a rectifier of a power supply. A second terminal is coupled to a first input terminal of a switching converter of the power supply. A third terminal is coupled to a second output terminal of the rectifier and a second input terminal of the switching converter. A variable resistance circuit is coupled between the first and second terminals. A control circuit is coupled between the first and third terminals and coupled to control the variable resistance circuit. A resistance of the variable resistance circuit is responsive to a magnitude of a voltage between the first and third terminals.

  • Patent number: 8907577
    Abstract: A circuit includes an input to be coupled to receive a rectified line voltage having a controlled conduction phase angle in each half line cycle. An active device is coupled to a feedback terminal of a controller. The feedback terminal is coupled to receive a feedback signal representative of an output of a power supply. The active device includes a control terminal coupled to receive a signal representative of the input. The active device is coupled to adjust the feedback signal on the feedback terminal in response to the control of the conduction phase angle of the rectified line voltage in each half line cycle.

  • Patent number: 5866210
    Abstract: A method for coating a substrate having a plurality of channels with a coating media in which the substrate is partially immersed into a vessel containing a bath of the coating media with the volume of coating media lying above the end of the immersed substrate being sufficient to coat the substrate to a desired level. A vacuum is then applied to the partially immersed substrate at an intensity and time sufficient to draw the coating media upwardly from the bath into each of the channels to form a uniform coating profile therein.
