  • Publication number: 20260054018
    Abstract: An e-vapor device may include a capsule, a mouthpiece configured to receive the capsule, and a vaporizer configured to engage with the mouthpiece to enclose the capsule therebetween. The capsule is configured to hold a pre-vapor formulation therein. The vaporizer is configured to pierce the capsule to access the pre-vapor formulation therein and to heat the pre-vapor formulation to generate a vapor. Additionally, the vaporizer may be configured to cease a heating of the pre-vapor formulation when a current in the heater structure is less than a reference level. Accordingly, the occurrence of an unpleasant taste resulting from overheating may be reduced or prevented.

  • Publication number: 20250351236
    Abstract: A method of forming a heater assembly of an e-vaping device includes bending a wire to form a first lobe and bending the wire to form a second lobe. The first lobe and the second lobe form a generally sinuously-shaped heater having a first set of lobes and a second set of lobe. A first apex of the first lobe is generally opposite a second apex of the second lobe. The method may also include curling the first set of lobes towards the second set of lobes to form a heater having a substantially tubular form. The heater defines an opening there through.

  • Publication number: 20250248569
    Abstract: The present system provides a tamale press that is simple to operate and allows a person to make 75-100 tamales per hour. The device is designed to be used to make tamales and avoids the disadvantages of a tortilla press. The device comprises a base with a cavity for receiving a portion of masa to be pressed. A top portion is hingedly coupled to the base and includes a protruding section that approximately matches the dimensions of the cavity in the base. The top portion is closed and a pivoting handle is used to apply pressure to the device, causing the protruding section to press and spread the masa to the borders of the cavity in the base. When the handle and top are lifted, the formed tamale is removed and the next tamale can be produced.

  • Publication number: 20250099693
    Abstract: A capsule for a heat-not-burn (HNB) aerosol-generating device may include a first frame, a second frame, a first heater, a second heater, and/or an aerosol-forming substrate. The first frame has a first interior face and a first exterior face. In addition, the first frame defines a first opening. The first heater may be secured to the first frame so as to cover the first opening. The second frame is connected to the first frame. The second frame has a second interior face and a second exterior face. Furthermore, the second frame defines a second opening. The second heater may be secured to the second frame so as to cover the second opening. The aerosol-forming substrate may be between the first heater and the second heater.

  • Publication number: 20240387792
    Abstract: Metrology systems and processing methods for continuous lithium ion battery (LIB) anode pre-lithiation and solid metal anode protection are provided. In some embodiments, the metrology system integrates at least one complementary non-contact sensor to measure at least one of surface composition, coating thickness, and nanoscale roughness. The metrology system and processing methods can be used to address anode edge quality. The metrology system and methods can facilitate high quality and high yield closed loop anode pre-lithiation and anode protection layer deposition, alloy-type anode pre-lithiation stage control improves LIB coulombic efficiency, and anode coating with pinhole free and electrochemically active protection layers resist dendrite formation.

  • Publication number: 20240382334
    Abstract: An off-loading wrist brace featuring a linear configuration, a split linear configuration, or a glove configuration with a thumb hole, pisiform hole, purlicue saddle, and closure components. The brace compresses to reduce repetitive movement of the carpal ligament while reducing compression of the pisiform to reduce injury and pain. The brace is removably affixed by placing the thumb through the thumb hole, wrapping the brace body around the wrist to attach the closure component at the tapered distal end to the closure component at the rounded proximal end.
