Patent number: 10194498Abstract: Power consumption in a start-up circuit for a LED-based light bulb may be reduced by digitally switching a transistor of the start-up circuit coupled to the input voltage. When the transistor is digitally switched between on and off, a reduced amount of power is dissipated by the transistor, because it may not enter a saturation region of operation where the resistance of the transistor between drain and source terminals increases. The transistor may be coupled to a voltage regulator for generating one or more output voltages, including a supply voltage for a host controller IC. The transistor may be switched on and off by a digital signal generated by logic circuitry, which may decide to switch the transistor on and off based on a voltage level at an output of the voltage regulator.Type: GrantFiled: August 28, 2017Date of Patent: January 29, 2019Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Erik J.

Patent number: 10172227Abstract: The invention relates to a plasma accelerator that produces and controls a plasma stream exhaust, in particular for space propulsion. The ions are produced inside the discharge chamber by working gas collisional ionization by electrons from a single electron source placed outside, also employed for ion beam neutralization. The ion motion is directed outwards through the exit side by the electric field between a cathode grid and the walls of the plasma chamber. The acceleration voltage imparts energy to the ion flux and an electrically biased control grid modulates the ion outflow from the discharge chamber and the electron inflow from the electron source. This allows electrical control of throttle and/or modulation of thrust delivered along the longitudinal direction of the thruster axis. Several plasma accelerators could be clustered together to provide controlled non-axial thrust using the individual control of throttle.Type: GrantFiled: October 27, 2015Date of Patent: January 1, 2019Assignees: AERNNOVA, UNIVERSIDAD POLITECNICA DE MADRIDInventors: Miguel Angel Castillo Acero, Luis Conde Lopez, Juan Luis Domenech Garret, Jose Manuel Donoso Vargas, Ezequiel Del Rio Fernandez
