Patent number: 10540885Abstract: 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.Type: GrantFiled: May 26, 2017Date of Patent: January 21, 2020Assignee: SIEMENS SCHWEIZ AGInventors: Hong Xiang Liang, Xue Song Shen, Jian Tan

Patent number: 10137166Abstract: Compositions which self-assemble under physiological conditions are formulated for application to wounds. The formulations include a pharmaceutically acceptable carrier or are provided as part of a medical device or coating. The formulations may also include other therapeutic, prophylactic or diagnostic agents. The formulation can be administered for treatment of one or more disorders or conditions. For example, the formulation may be applied to repair an injury or during surgery of the lung, eye or dura, or following an epidural or spinal tap, to stop leakage of blood, interstitial fluid, or cerebrospinal fluid. The formulation may be administered to a burn or ulcer. In one embodiment, the formulation is provided as a dry or lyophilized powder. In another embodiment, the material is provided in water. In another embodiment, the material is provided in combination with an oil and forms a laminate.Type: GrantFiled: November 2, 2016Date of Patent: November 27, 2018Assignees: Massachusetts Institute of Technology, Versitech LimitedInventors: Rutledge Ellis-Behnke, Yu-Xiang Liang, Gerald E.

Publication number: 20160296660Abstract: 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.Type: ApplicationFiled: April 5, 2016Publication date: October 13, 2016Applicants: Massachusetts Institute of Technology, Versitech LimitedInventors: Rutledge Ellis-Behnke, Yu-Xiang Liang, Gerald E.

Patent number: 8971051Abstract: A chip card ejecting mechanism includes a base body, a push member, a rotating member and an elastic member resisting between the base body and the rotating member. The base body includes a guiding member defining a hole and having a number of guiding rails. Each guiding rail includes a resisting surface and a guiding surface. The push member includes a push rod extending through the hole and a number of active gears. Each active gear defines an active cooperative surface. The rotating member includes a number of the passive gears. Each passive gear includes a passive cooperative surface. When the push member is pressed toward the rotating member by a transient external force, the rotating member compresses the elastic member until the active cooperative surface arrives at the guiding surface, the elastic member releases and drives the passive cooperative gears to slide along the first sliding slot.Type: GrantFiled: April 17, 2013Date of Patent: March 3, 2015Assignees: Shenzhen Futaihong Precision Industry Co., Ltd., FIH (Hong Kong) LimitedInventor: Hua-Xiang Liang
