Abstract: The present invention discloses an immersion type heat dissipation cooling liquid for power lithium battery and a method for preparing thereof. It is composed of 30 parts to 70 parts of hydrofluoroether compound, 30 parts to 50 parts of halogenated hydrocarbon, 1 part to 10 parts of alcohol compound, 0.01 parts to 0.5 parts of antioxidant, 0.01 parts to 0.5 parts of preservative, and 0.01 parts to 0.5 parts of nano metal oxide. The present invention mainly includes the hydrofluoroether compound, which is mixed with the halogenated hydrocarbon, the alcohol and other compounds to form an azeotrope, and is supplemented with antioxidant, preservative and non-conductive nano metal oxide additive to form a cooling liquid composition. The present invention can quickly realize the heat transfer effect, effectively solve the problem of heat generation and heat dissipation of the power lithium battery.

Abstract: An adjustable joint brace with a telescopically adjustable length, having a strap and a plurality of supports; the strap has first and second straps connected through a rotatable adjustment device so that an angle between the first and second straps is adjustable; buckling holes spaced with one another are arranged on the strap along a lengthwise direction; each support has an elastic buckle buckled to one of the buckling holes selected as desired, so each support is fastened onto the strap. The joint brace is adaptable to patients with different heights and sizes and adaptable to different joints.

Abstract: Provided are a low dropout regulator and an electronic device. The low dropout regulator comprises a control unit electrically connected to a second capacitor, the control unit being used for controlling the connection or disconnection between a first electrode plate of the second capacitor and a second end of a power tube. Therefore, when the low dropout regulator is in a standby state, the control unit controls the disconnection between the first electrode plate of the second capacitor and the second end of the power tube, such that the second end of the power tube has a relatively small connection capacitance, so as to ensure the separation of a dominant pole point at a control end of the power tube from a secondary pole point at the second end of the power tube, and thus, the low dropout regulator has a high loop stability when same is in the standby state, thereby improving the performance of the low dropout regulator.

Abstract: Techniques reduce the effects of power supply noise on a signal provided by a single-ended complementary metal-oxide semiconductor (i.e., CMOS) input buffer circuit capable of receiving an input signal having one of a variety of acceptable formats, while generating the signal to have substantially the same duty cycle as the input signal. The techniques include one or more of AC coupling, hysteresis, and voltage biasing applied to the input buffer circuit.
