Publication number: 20090165769Abstract: The invention relates to a solid fuel stove comprising a combustion chamber (12) for containing combustion fuel and a blower assembly (50) configured to provide airflow entering the combustion chamber in operating condition. When guiding means (40) establish airflow entering the combustion chamber substantially in a downwardly direction the combustion process of the stove is very clean and efficient.Type: ApplicationFiled: June 20, 2007Publication date: July 2, 2009Applicant: HIGH TECH CAMPUS 44Inventor: Paul Van Der Sluis

Publication number: 20090072212Abstract: A One Time Programmable (OTP) memory cell (10) comprising a first, metallic layer (12) coated with a second, conductive stable transition compound (14) with an insulating layer (16) there-between. The first and second layers (12, 14) are selected according to the difference in Gibbs Free Energy between them, which dictates the chemical energy that will be generated as a result of an exothermic chemical reaction between the two materials. The materials of the first and second layers (12, 14) are highly thermally stable in themselves but, when a voltage is applied to the cell (10), a localized breakdown of the insulative layer (16) results which creates a hotspot (18) that sets off an exothermic chemical reaction between the first and second layers (12, 14). The exothermic reaction generates sufficient heat (20) to create a short circuit across the cell and therefore reduce the resistance thereof.Type: ApplicationFiled: May 4, 2006Publication date: March 19, 2009Applicant: NXP B.V.Inventors: Paul Van Der Sluis, Andrei Mijiritskii, Pierre H. Woerlee, Victor M.G. Van Acht, Nicolaas Lambert

Publication number: 20090025703Abstract: A solid fuel, portable stove reduces smoke emissions and provides for a high temperature of combustion in a compact and easily manufacturable design. A main housing (11) comprises a combustion chamber (12) for containing fuel for combustion and a fan (50) configured to force air into the combustion chamber. A rechargeable electrical power source (40) is used for driving the fan (50) and a thermoelectric (31) provides power to the fan and to the rechargeable power source. In one embodiment, the thermoelectric element also provides excess output power to a connected device (D) such as a low voltage white light emitting diode, thereby providing a self illuminating, rechargeable stove which is suitable for sunset or early evening cooking.Type: ApplicationFiled: March 27, 2006Publication date: January 29, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Paul Van Der Sluis, Sudhakaran Subbu

Patent number: 7291505Abstract: The invention relates to a ferroelectric device (10) with a body (11) comprising a substrate (1) and a ferroelectric layer (2) provided with a connection conductor (3) on a side facing away from the substrate (1), which ferroelectric layer contains an oxygen-free ferroelectric material (2) and is used to form an active electrical element (4), in particular a memory element (4). Such a device forms an attractive non-volatile memory device. In accordance with the invention, a conductive layer (5) is present between the substrate (1) and the ferroelectric layer (2), which conductive layer forms a further connection conductor (5) of the ferroelectric layer (2), and the active electrical element (4) is obtained as a result of the fact that the ferroelectric layer (2) forms a Schottky junction with at least one of the connection conductors (3, 5).Type: GrantFiled: July 10, 2003Date of Patent: November 6, 2007Assignee: NXP B.V.Inventors: Paul Van Der Sluis, Martijn Henri Richard Lankhorst, Ronald Martin Wolf

Patent number: 7192533Abstract: In the method, semiconductor substrates are etched to provide nanowires, said substrates comprising a first layer of a first material and a second layer of a second material with a mutual interface, which first and second materials are different. They may be different in the doping type. Alternatively, the main constituent of the material may be different, for example SiGe or SiC versus Si, or InP versus InAs. In the resulting nanowires, the interface is atomically sharp. The electronic devices having nanowires between a first and second electrode accordingly have very good electroluminescent and optoelectronic properties.Type: GrantFiled: March 23, 2003Date of Patent: March 20, 2007Assignee: Koninklijke Philips Electronics N.V.Inventors: Erik Petrus Antonius Maria Bakkers, Freddy Roozeboom, Johannes Fransiscus Cornelis Maria Verhoeven, Paul Van Der Sluis

Patent number: 6680790Abstract: The invention relates to a switching mirror display having an increased aperture. The display comprises pixel elements (20) having a switchable layer (3), which is switched between a reflecting and an absorbing state by changing a hydrogen content of the switchable layer (3). Applying a DC voltage on electroconductive layers (11, 13) changes the hydrogen content. These electroconductive layers (11, 13) sandwich a stack of layers comprising the switchable layer (3), which stack has been deposited on a transparent substrate (1). The display is being viewed from a side (24) of the substrate on which the stack is deposited. The pixel element (20) is driven by an active matrix element (22). The switchable layer (3) extends across the active matrix element (22) and conceals this element. This increases the aperture of the display.Type: GrantFiled: September 27, 2001Date of Patent: January 20, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Mark Thomas Johnson, Paul Van Der Sluis, Anna-Maria Janner, Hugo Johan Cornelissen

Publication number: 20030227667Abstract: A description is given of a switching device (1) comprising a transparent substrate (3), a switching film (5) comprising a hydride of scandium and magnesium, covered with a palladium layer (7). By exchange of hydrogen, the switching film can be reversibly switched from a transparent state to a mirror-like state with zero transmission via an intermediate black absorbing state. The conversion between both states is reversible, and this phenomenon can be used, for example, in an optical switching element or sun roof.Type: ApplicationFiled: June 16, 2003Publication date: December 11, 2003Inventors: Martin Ouwerkerk, Anna-Maria Janner, Paul Van Der Sluis, Virginie Marie Marguerite Mercier

Patent number: 6535323Abstract: The invention relates to a switching device having shorter switching times. The device comprises a switchable layer (3), which is switched between a reflecting and an absorbing state by changing a hydrogen content of the switchable layer (3). Applying a DC voltage on electroconductive layers (11, 13) changes the hydrogen content. These electroconductive layers (11, 13) sandwich a stack of layers comprising the switchable layer (3) and a hydrogen storage layer (9). The hydrogen storage layer comprises essentially the same compounds as the switchable layer (3), viz. LMgHx and preferably GdMgHx. The storage layer may be made thin, leading to relatively short hydrogen transportation times and a relatively fast display. The device may be further improved by applying a scattering foil.Type: GrantFiled: September 27, 2001Date of Patent: March 18, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Mark Thomas Johnson, Paul Van Der Sluis, Anna-Maria Janner, Hugo Johan Cornelissen
