  • Publication number: 20190374226
    Abstract: The present disclosure concerns embodiments of an implantable perfusion device that can be implanted in an injured blood vessel to control bleeding without occluding the vessel. In one specific implementation, the perfusion device can be implanted percutaneously into a patient's descending aorta to control bleeding at the site of a ruptured portion of the aorta (known as torso hemorrhage) while still allowing for the antegrade flow of blood from a location upstream of the ruptured portion of the aorta to a location downstream of the ruptured portion of the aorta. The perfusion device can be left inside the patient as the patient is transported to a medical facility where the injury can be repaired. Following repair of the vessel, the perfusion device can be withdrawn from the patient.

  • Patent number: 8362977
    Abstract: A method of driving a plasma display is disclosed. In one embodiment, the method includes dividing one screen into a plurality of areas, wherein each area corresponds to at least one of the plurality of discharge cells, and wherein the plurality of areas form a detection pattern. The method also includes displaying the detection pattern in the plasma display and receiving a detection image which has been previously detected or captured, wherein detection image corresponds to at least one of the plurality of areas. The method further includes comparing the received detection image with the detection pattern and determining a position of the detected or captured area based on the comparison.

  • Publication number: 20110152379
    Abstract: The present invention relates to a composition for controlling aging and/or extending lifespan. More specifically, the present invention relates to a composition containing dapsone as an effective component for controlling aging and/or extending lifespan, in which when applying the composition according to the present invention to an object, the effect of controlling aging or extending lifespan is excellent. Specifically, the treatment of dapsone (DDS) increases the lifespan of C. elegans not depending upon daf-16 and delays aging process, and reduces the activity of cytoplasmic dual oxidase 1 (Duox1) and mitochondria complex V protein. In addition, dapsone can maintain the low oxygen uptake rate in C. elegans thereby reducing ROS formation. In addition, ROS production by paraquat that is an inducing material of oxidative stress is reduced by treating dapsone and the sensitivity of paraquat is reduced.

  • Publication number: 20070008246
    Abstract: In a plasma display and a method of driving a plasma display, a discharge is generated in a sustain period since a first voltage is supplied to a scan electrode and a second voltage lower than the first voltage is supplied to a sustain electrode. Accordingly, a discharge current flows since wall charges are formed on the scan and sustain electrodes as a result of the discharge. When the discharge current flows, a third voltage lower than the first voltage and higher than the second voltage is supplied to the sustain electrode while the first voltage is supplied to the scan electrode. In addition, when another discharge current flows since a sustain discharge is generated by supplying the first voltage to the sustain electrode and suypplying the second voltage to the scan electrode, the third voltage is supplied to the scan electrode while the first voltage is supplied to the sustain electrode.

  • Publication number: 20060061523
    Abstract: In a plasma display device and driving method thereof, middle electrodes are formed between X electrodes for receiving a sustain pulse voltage and Y electrodes. A reset waveform and a scan pulse voltage are applied to the middle electrodes. A short-gap discharge is performed between the X electrode and the middle electrode in the earlier stage of a sustain discharge period, and a long-gap discharge is normally performed between the X electrode and the Y electrode after the earlier stage of the sustain discharge period, thereby performing stable discharge. Further, the number of switches of the M electrode driver may be reduced by floating the M electrode and applying a rising ramp waveform to the Y electrode in the reset period, thereby increasing the voltage at the M electrode.
