摘要:
The present application discloses a method and device of detecting fatigue driving, comprising: analyzing an eye image in the driver's eye image area with a rectangular feature template to obtain the upper eyelid line; determining the eye closure state according to the curvature or curvature feature value of the upper eyelid line; and collecting statistics on the eye closure state and thereby determining whether the driver is in a fatigue state. The present application determines whether the eyes are opened or closed according to the shape of the upper eyelid, which is more accurate because the upper eyelid line has characteristics of higher relative contrast, anti-interference capacity, and adaptability to the changes in the facial expression.

A cable having a current leakage detection function includes three current-carrying core wires. Each current-carrying core wire is wrapped by an insulating layer, so that the current-carrying core wires are electrically insulated from one another. The insulating layer of at least one of the current-carrying core wires is wrapped by a metal wire net. Current guiding wires in contact with the metal wire net or a single-sided conductive film laminated outside the metal wire net is utilized to achieve the effect of timely and effectively conducting a leakage current to a leakage current detection device, so as to improve the reliability of leakage current detection.

摘要:
A high sensitivity leakage current detection interrupter (LCDI) includes a shielded wire, a current leakage detection unit, and a tripping mechanism. A live core and a neutral core of the shielded wire are respectively wrapped in two conductive shell wires. The current leakage detection unit includes a pair of rectifying diodes reversely connected in series between a live line and a neutral line of a power supply, a voltage dropping resistor, thyristors, and resistor-capacitor (RC) voltage dropping filter circuits. The tripping mechanism includes control units with on/off respectively controlled by the thyristors. When either of the thyristors is turned on, the corresponding control unit is turned on, and the tripping mechanism is actuated to switch off the power supply.

The invention relates generally to a new functional protein S assay and kit that is based on the ability of endogenous protein S to prolong clotting time. In the assay procedure, a test plasma sample is diluted with protein S deficient plasma, followed by the addition of purified or recombinant tissue factor (pTF or rTF), purified natural or synthetic phospholipid (pPL or sPL) and activated protein C (APC) or protein C activator (PCA). The clotting time is then measured and compared to a standard curve or a normal control.
