  • Publication number: 20230347414
    Abstract: Electron beam powder bed fusion may be performed using waste powder from laser beam powder bed fusion by pre-heating a build chamber using stepped increases of electron beam current. To perform the pre-heating without smoking the powder, a plurality of predetermined interim temperatures, ranging from an ambient, resting temperature of the build chamber to a predetermined preheated temperature, are determined. A build plate within the build chamber is exposed to a plurality of streams of electrons, one at a time, while the build plate is surrounded by the waste powder. Each stream of electrons has a progressively increasing current, with the current being increased each time an actual temperature of the build chamber reaches or exceeds the next predetermined interim temperature. The actual temperature of the build chamber is monitored during the pre-heating, to compare the actual temperature of the build chamber to the plurality of predetermined interim temperatures.

  • Publication number: 20230208188
    Abstract: In an energy harvesting system, a power extraction circuit extracts electrical power from an environmental power source susceptible of providing a level of power that fluctuates. An electrical power storage device stores the electrical power extracted from the environmental power source by the power extraction circuit. A sensing circuit provides an indication of a level of power that the power extraction circuit can extract from the environmental power source. A controlled switch circuit electrically decouples the power extraction circuit from the electrical power storage device when the indication indicates that the level of power that the power extraction circuit can extract from the environmental power source is insufficient for the power extraction circuit to charge the electrical power storage device. This prevents leakage of harvested power.

  • Patent number: 9807326
    Abstract: In an image sensor, a front-end circuit provides an output signal indicative of the amount of light in response to at least one input signal. The front-end circuit includes a transistor having a threshold voltage that affects a relationship between the output signal and the level of the detection quantity. This transistor has a biasing node via which a biasing voltage can be applied to a semiconductor region that affects the threshold voltage of the transistor. A replica of the front-end circuit receives at least one defined input signal, among which is a substitute of the detection quantity having a defined level. The replica is arranged in a control loop that controls the biasing voltage that is applied to the biasing node in the replica, so that the replica provides a defined output signal. This biasing voltage is then also applied to the biasing node in the front-end circuit.

  • Patent number: 9743023
    Abstract: In an image sensor, a photo detector circuit applies a photo current to a capacitive node during a photo detection time interval. A front-end circuit comprises an input transistor having a control node that is coupled to the capacitive node. A switchable biasing arrangement puts the input transistor in a disabled state during the photo detection time interval. The input transistor is put in an enabled state after the photo detection time interval. This then causes the front-end circuit to provide an output signal that is representative of a voltage on the capacitive node after the photo detection time interval.
