  • Patent number: 10888304
    Abstract: Methods and system for producing combined photoacoustic/ultrasonic image frames use a low-power narrow beam laser to direct sequential pulses along a path overlying an internal region of interest. Photoacoustic responses are received and used to generate sub-frames. Between each of the laser pulses a plurality of ultrasound pulse-echo beams are sequentially emitted towards the region of interest, and the reflections are received and used to generate ultrasound sub-frames. The photoacoustic sub-frames are combined to produce a photoacoustic frame, and the ultrasound sub-frames are combined to produce an ultrasound frame. The photoacoustic and ultrasound frames are combined to produce an image frame. The method and system are suitable for producing real-time, high-contrast video.

  • Publication number: 20210000657
    Abstract: Apparatus and methods are provided to allow for creation of an elastic laminate. Non-stretched elastic can be laid at peaks over a nonwoven layer contained in valleys and atop peaks. Stretched elastic can be laid over tented nonwoven to create nonwoven tunnels when a second nonwoven is laid atop the first nonwoven and elastic, and the tunnels resist un-stretching of stretched elastic strands by frictional or obstruction forces. An elastic assembly or structure comprising a first and second layer of material bonded at spaced apart bond sites is disclosed, with a plurality of elastic strands disposed in a non-linear manner between said first and second layer of material, so that said strands meander in a cross-machine direction and traverse a machine direction line, restraining movement of the strands by frictional forces between the strands and the non-woven layers.

  • Publication number: 20200385412
    Abstract: A dibenzoheterocyclic compound wherein band gaps of HOMO and LUMO energy levels of the dibenzoheterocyclic compound are wide, light can be emitted in a deep blue light-emitting region; and the LUMO energy level of the dibenzoheterocyclic compound is low, so the LUMO energy level matches with an electron transport layer for electrons injection and transport. The dibenzoheterocyclic compound has hole transport performance, so as a light-emitting layer material, the dibenzoheterocyclic compound balances the ratio of electrons to holes in a light-emitting layer increasing the combination probability and improving the device light-emitting efficiency. The spatial configuration of the dibenzoheterocyclic compound avoids material stacking molecules, reduces annihilation of excitons, and inhibits efficiency roll-off. The dibenzoheterocyclic compound has thermal stability, so deep blue light can be emitted efficiently and stably.
