Patent number: 12100288Abstract: A system providing various improved calibration techniques for haptic feedback is described. An acoustic field is defined by one or more control points in a space within which the acoustic field may exist. Each control point is assigned an amplitude value equating to a desired amplitude of the acoustic field at the control point. Because complete control of space is not possible, controlling the acoustic field at given points yields erroneous local maxima in the acoustic field levels at other related positions. In relation to mid-air haptic feedback, these can interfere in interactions with the space by creating secondary effects and ghost phenomena that can be felt outside the interaction area. The level and nature of the secondary maxima in the acoustic field is determined by how the space is controlled. By arranging the transducer elements in different ways, unwanted effects on the acoustic field can be limited and controlled.Type: GrantFiled: July 27, 2023Date of Patent: September 24, 2024Assignee: ULTRAHAPTICS IP LTDInventors: Thomas Andrew Carter, Benjamin John Oliver Long

Some embodiments provide photonic communication platforms that involve use of photonic modules. Each photonic module includes programmable photonic circuits for placing the module in optical communication with other modules based on the needs of a particular application. The architecture developed by the inventors relies on the use of common photomask sets (or at least one common photomask) to fabricate multiple photonic modules in a single wafer. Photonic modules in multiple wafers can be linked together into a communication platform using optical or electronic means.Type: GrantFiled: December 1, 2023Date of Patent: July 16, 2024Assignee: Lightmatter, Inc.Inventors: Nicholas C.

Patent number: 12034025Abstract: An imaging device may include single-photon avalanche diodes (SPADs). To mitigate crosstalk, isolation structures may be formed around each SPAD. The isolation structures may include front side deep trench isolation structures that extend partially or fully through a semiconductor substrate for the SPADs. The isolation structures may include a metal filler such as tungsten that absorbs photons. The isolation structures may include a p-type doped semiconductor liner to mitigate dark current. The isolation structures may include a buffer layer such as silicon dioxide that is interposed between the metal filler and the p-type doped semiconductor liner. The isolation structures may have a tapered portion or may be formed in two steps such that the isolation structures have different portions with different properties. An additional filler such as polysilicon or borophosphosilicate glass may be included in some of the isolation structures in addition to the metal filler.Type: GrantFiled: May 13, 2021Date of Patent: July 9, 2024Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Jeffrey Peter Gambino, David T.

Patent number: 12025555Abstract: A photodetector comprises a substrate, and supported by the substrate, a configuration to act as optical resonator and to absorb incident radiation of a band, including infrared. The configuration comprises: a resonant frontside structure facing the incident radiation; a backside structure and arranged between the frontside structure and the substrate; and a layer of an active material made from a semiconducting material, and configured to convert at least part of the incident radiation of the band into charge carriers. The frontside structure or the backside structure is made from electrically conducting material and is in contact with the active material. The configuration is configured to selectively absorb the incident radiation of the band. The frontside structure or the backside structure that is in contact with the active material is contacted by electrical contacts for sensing the charge carriers in the active material. The active material comprises amorphous or polycrystalline material.Type: GrantFiled: June 19, 2020Date of Patent: July 2, 2024Assignee: SENSIRION AGInventors: Alexander Dorodnyy, Alexander Lochbaum, Jürg Leuthold, Lukas Bürgi, Silvio Graf

Patent number: 12015046Abstract: Back-illuminated DUV/VUV/EUV radiation or charged particle image sensors are fabricated using a method that utilizes a plasma atomic layer deposition (plasma ALD) process to generate a thin pinhole-free pure boron layer over active sensor areas. Circuit elements are formed on a semiconductor membrane's frontside surface, and then an optional preliminary hydrogen plasma cleaning process is performed on the membrane's backside surface. The plasma ALD process includes performing multiple plasma ALD cycles, with each cycle including forming an adsorbed boron precursor layer during a first cycle phase, and then generating a hydrogen plasma to convert the precursor layer into an associated boron nanolayer during a second cycle phase. Gasses are purged from the plasma ALD process chamber after each cycle phase. The plasma ALD cycles are repeated until the resulting stack of boron nanolayers has a cumulative stack height (thickness) that is equal to a selected target thickness.Type: GrantFiled: December 7, 2021Date of Patent: June 18, 2024Assignee: KLA CorporationInventors: Sisir Yalamanchili, John Fielden, Francisco Kole, Yung-Ho Alex Chuang
