  • Publication number: 20250090291
    Abstract: A method for dispensing an oral care composition includes dispensing the oral care composition through a nozzle to form a dispensed composition. The nozzle includes an orifice having a central axis and an orifice diameter, and fins partially occluding the orifice, where each of the fins has an upper surface and a lower surface. The dispensed composition has an increased flavor display compared to a control dispensed composition made by dispensing the oral care composition through a control nozzle comprising an unobstructed, circular orifice having the orifice diameter.

  • Publication number: 20250045374
    Abstract: Disclosed are various approaches for relationship and attribute management are described. In some examples, a verifier service performs a verification process using a relationship decentralized identifier (DID) that provides proof of a relationship between the holder and a DID management service. An attribute request is that specifies an attribute is transmitted from the verifier service to the DID management service. The DID management service provides the verifier service with information based on the attribute once the holder provides an authorization response that authorizes usage of the attribute.

  • Publication number: 20250028255
    Abstract: A method for determining values of design variables of a lithographic process based on a predicted failure rate for printing a target pattern on a substrate using a lithographic apparatus. The method includes obtaining an image corresponding to a target pattern to be printed on a substrate using a lithographic apparatus, wherein the image is generated based on a set of values of design variables of the lithographic apparatus or a lithographic process; determining image properties, the image properties representative of a pattern printed on the substrate, the pattern corresponding to the target pattern; predicting a failure rate in printing the pattern on the substrate based on the image properties; and determining a specified value of a specified design variable based on the failure rate, the specified value to be used in the lithographic process to print the target pattern on the substrate.

  • Patent number: 8027142
    Abstract: Methods and apparatus are provided for driving an ignition exciter unit. An apparatus is provided for a driver circuit for use with an ignition exciter unit, the driver circuit having an input terminal and an output terminal. A first current-protected circuit is coupled to the input terminal and the output terminal, wherein the first current-protected circuit is current-limited. A second current-protected circuit coupled to the input terminal and the output terminal. The driver circuit further comprises a controller coupled to the first current-protected circuit and the second current-protected circuit. The controller is configured to activate the first current-protected circuit for a first time interval and activate the second current-protected circuit after the first time interval and prior to when the ignition exciter unit begins operating.

  • Patent number: 7292071
    Abstract: A circuit and method thereof for sampling/holding signal is provided. The signal sampling/holding circuit comprises a first signal sampling/holding device, a second signal sampling/holding device, a target signal and a reference voltage. First, the first signal sampling/holding device is supplied with the reference voltage and the target signal. The reference voltage is disconnected from the first signal sampling/holding device before the target signal is. Similarly, the reference voltage is disconnected from the second signal sampling/holding device before the target signal is. Thus the target signal is respectively sampled and held in the first signal sampling/holding device and the second signal sampling/holding device.

  • Patent number: 7274009
    Abstract: A frame shuttered CMOS image sensor with simultaneous array readout. An array of CMOS pixels are printed on a silicon substrate. Within each pixel is a light sensitive region comprising a photo sensitive diode for converting photons into electrical charge and at least three transistors to permit reading of reset electrical charges and collected electrical charges and for re-setting the photosensitive diode. The sensor includes an array of signal and re-set readout capacitors located on the substrate but outside of the pixel array. Metal conductors printed in said substrate connect each pixel in said pixel array with a signal capacitor and a re-set capacitor in array of signal and re-set readout capacitors. Transistor switches printed in said substrate but outside of said pixel array are used to isolate the signal and re-set capacitors from each other and from the pixels.
