Patent number: 11462674Abstract: The present invention discloses a method for creating spin-affected electric currents passively and feeding them into electric devices. The invention can be realized as either a rectangular black box incorporating coatings on top of and on the bottom of a conducting volume of material, or by coating a round-shaped wire or thread(s) of a cable. This is obtained by using a specific coating material on the conducting piece of material. The material may be piezoelectric, such as silicon dioxide (i.e. quartz) but also silicon carbide (SiC) may be used. Also, mixtures and composite arrangements are possible in order to create a coating. The manufactured add-on unit, when supplied with the input power or input signal, will act as an electron spin feeding device to the electric device because the electrons will be moving strongly within the interface area of the coating and the conducting material with aligned spins.Type: GrantFiled: June 12, 2018Date of Patent: October 4, 2022Assignee: Spindeco Technologies OyInventors: Pekka Tapani Saastamoinen, Petteri Koljonen, Reijo Lappalainen

Next, the battery (204, 300) has been manufactured so that the battery includes either ferroelectric or pyroelectric material at least either in an anode (305), in a cathode (302), or in an other element of the battery (204, 300). The material can be selected to be polyvinylidene fluoride (“PVDF”) or modified materials thereof. After at least one cycle of charging of the battery (204, 300), the battery (204, 300) with reduced internal resistance is obtained.Type: ApplicationFiled: July 10, 2020Publication date: August 18, 2022Inventors: Pekka Tapani SAASTAMOINEN, Reijo LAPPALAINEN, Petteri KOLJONEN

Publication number: 20120244032Abstract: In order to produce a coating on a substrate, the substrate is placed adjacent to a target. Material is cold ablated off the target by focusing a number of consecutive laser pulses on the target, thus producing a number of consecutive plasma fronts that move at least partly to the direction of said substrate. The time difference between said consecutive laser pulses is so short that constituents resulting from a number of consecutive plasma fronts form a nucleus on a surface of the substrate where a mean energy of said constituents allows the spontaneous formation of a crystalline structure.Type: ApplicationFiled: October 4, 2010Publication date: September 27, 2012Applicant: PICODEON LTD OYInventors: Reijo Lappalainen, Vesa Myllymäki, Jukka Häyrynen
