  • Publication number: 20240112696
    Abstract: A heat-assisted magnetic recording head includes a laser, a near-field transducer, a primary waveguide, a secondary waveguide, and a photodiode. The laser is configured to emit electromagnetic radiation. The near-field transducer is configured to focus and emit an optical near-field. The primary waveguide configured to receive the electromagnetic radiation and propagate the electromagnetic radiation toward and proximal to the near-field transducer. The secondary waveguide configured to receive a portion of the electromagnetic radiation from the primary waveguide. The photodiode configured to receive the portion of the electromagnetic radiation from the secondary waveguide and emit a signal that represents a magnitude of the electromagnetic radiation that the laser emits.

  • Patent number: 11918790
    Abstract: A drug injection device includes a last dose setting having a main drive pin, a drive wheel, a driven wheel, an abutment element fixedly coupled to, or integrally formed with, the driven wheel. The drive wheel has a rotation axis parallel to a longitudinal axis and is configured to be driven about the longitudinal axis by a knob and to be periodically driven in rotation about the rotation axis by the main drive pin, during a drug dose setting. The driven wheel has a second rotation axis parallel or coaxial to said longitudinal axis and is configured to be periodically driven about the longitudinal axis by the drive wheel. The abutment element is configured to prevent the rotation of the drive wheel about the longitudinal axis when the knob has made a predetermined number of full and/or partial rotations about the longitudinal axis correlated to the predetermined drug volume.

  • Patent number: 7504142
    Abstract: Film laminates for packaging applications having at least two polymer layers which are formed together as a coextruded blown film such that the first polymer layer is a surface layer relative to the film and comprises a heat-sealable material having a melt index of at least 20 g/10 min. The present invention further provides food packages formed from these film laminates.
