  • Patent number: 11839694
    Abstract: Compositions that include nanoscale structured materials or precursors thereof (e.g., self: assembling peptides) are described. The compositions can include other substances (e.g., a vasoconstrictor). Also described are methods for using the compositions to promote hemostasis, to protect the skin or wounds from contamination, to decontaiminate a site upon removal of previously applied compositions that provided a protective coating, and to inhibit the movement of bodily substances other than blood. The compositions are also useful in isolating tissue, removing tissue, preserving tissue (for, e.g., subsequent transplantation or reattachment), and as bulking, stabilizing or hydrating agents. Medical devices that include the compositions (e.g., a stent or catheter), bandages or other wound dressings, sutures, and kits that include the compositions are also described.

  • Publication number: 20230330907
    Abstract: A mold apparatus including a mold, a bearing structure, and a sensing module is provided. The mold has a cavity. The sensing module includes a temperature sensor and a pressure sensor. The temperature sensor has a sensing portion and an abutting portion. The sensing portion is located in the mold and corresponds to a position in the cavity, and the abutting portion is located in the bearing structure. The pressure sensor is disposed in the bearing structure and corresponds to the abutting portion. The abutting portion is adapted to abut against the pressure sensor by a pressure of the position in the cavity.

  • Patent number: 11491677
    Abstract: A retraction device includes: a spindle, a support plate and a plurality of spring washers. The spindle is movable along an axis direction thereof and has a first end; a support plate has a fixed position, the first end of the spindle penetrates the support plate; and the plurality of spring washers are fitted over the first end of the spindle and stacked together in an identical direction. The plurality of spring washers are compressed between the spindle and the support plate with a predetermined pre-load. The spindle is configured to be switchable between a first position and a second position, and capable of moving a predetermined distance relative to the support plate in the axis direction of the spindle during switching. When in the first position, the spindle is farthest from the support plate, when in the second position, the spindle is closest to the support plate.

  • Patent number: 10540885
    Abstract: The present disclosure generally relates to the field of fire alarms. The teachings thereof may be embodied in a strobe notification appliance having: a boost circuit connected to an input voltage; an energy storage circuit charged by the boost circuit; a drive circuit generating a drive current; an LED circuit with at least one LED element; a first sampling circuit collecting an overall voltage drop of all the LED elements; and a control circuit configured to adjust the drive circuit to supply a working current during an alarming stage and supply a detection current during a detection stage. The detection current is lower than the working current and thereby light energy produced by the LED elements during the detection stage is lower than alarming light energy produced during the alarming stage. During the detection stage, the control circuit determines whether the LED circuit works normally based on the collected overall voltage drop.
