A personal audio device including a flexible headband is disclosed. The flexible headband includes a left and right headband portion. The headband has a longitudinal centerline which occupies a substantially single plane. The personal audio device also includes a left earphone, which is secured to a first end of the left headband portion, and a right earphone, which is secured to a first end of the right headband portion. A connector portion connects a second end of the left headband portion with a second end of the right headband portion. The connector portion is linearly adjustable, which enables a distance between the left headband portion and right headband portion to be variable. A change in the distance causes an inversely proportional change in bent compression force applied by a left earphone and applied by the right earphone.

A regenerative braking method for a vehicle having an electric motor. During an initial stage of a regenerative braking operation related to the vehicle having the electric motor, a flow rate of brake liquid as much as the amount of regenerative braking is delivered into a reservoir through opened exit valves of non-driving wheels, so as to generate a hydraulic braking force needed after subtracting the amount of regenerative braking from the amount of braking desired by a vehicle operator. When the amount of regenerative braking increases, exit valves of driving wheels are controlled to fulfill the total amount of braking desired by the vehicle operator. Also, when the amount of regenerative braking decreases, wheel pressures have to be increased to fulfill the vehicle operator's desire to brake. In the regenerative braking method for generating a residual amount of braking needed after subtracting the amount of regenerative braking, which corresponds to an amount generated by the electric motor, from the amount of braking desired by the vehicle operator, during the regenerative braking operation, based on a pressure difference between a pressure in the master cylinder and wheel pressures, entrance valves of the driving wheels are controlled to realize an operator's pedal feeling, and the exit valves of the driving wheels are controlled to allow the wheel pressures to follow a target pressure.

The mute equipment capable of controlling a breath pressure may be further characterized in that the equipment has a section of adjusting a breath volume to adjust the size of the hole to release the breath. The mute equipment capable of controlling a breath pressure may be further characterized in that the section of adjusting a breath volume can use as the section of restricting the wind way width.

The invention provides an environment-friendly softening agent which is used for hand feeling finishing of fabric. The softening agent is a product obtained through the following steps: dehydrating raw materials: organic amine and fatty acid in nitrogen atmosphere with phosphorous as a catalyst at the temperature of 180-200 DEG C and then dehydrating under the vacuum condition at the temperature of 200-240 DEG C; and finally, performing quaterisation and acidification. According to the invention, the softening agent, which has good hand feeling and low yellowing performances consistent with those of a softening agent commonly used at present, can be obtained by replacing a raw material: AEEA (aminoethylethanolamine) of the softening agent commonly used at present with a series of organic amine such as hydroxy-propyl-ethylenediamine and the like under the condition that the molar ratio is not changed, so that the environment and health problems caused by AEEA can be solved.

The present invention relates to the technical field of skiing equipment, in particular to a center of gravity auxiliary stabilization teaching aid for snowboarding, comprising a skateboard body, two skateboard boots are arranged symmetrically on the skateboard body, and teaching aids are detachably installed on the top of the skateboard body The teaching aid board is provided with an avoidance groove for avoiding skateboard boots, and a traction mechanism is respectively arranged outside the two ends of the teaching aid board, and the two traction mechanisms are respectively elastically connected to the teaching aid board through a first elastic member , the two traction mechanisms can move toward each other or back, the upper area of ​​each traction mechanism is provided with a grasping mechanism that can be adjusted vertically, and the tail of the skateboard body is provided with a detachable booster mechanism. The invention can stably assist beginners to practice skiing, reduce the number of falls, and prevent giving up due to excessive difficulty in the early stage.

The invention discloses a method for self-adapting massage manipulative force. In the method for self-adapting massage manipulative force, by detecting the change of the pressure value of the massage wheel, it is determined that the current pressure value is greater than the first pressure value when the amount exceeds the preset threshold value. , compare the current pressure value with the pressure value of the calibration point in the first pressure value partition, adjust the farthest position to the position of the most suitable calibration point, and at the same time, the starting position of the massage technique is based on the most suitable The position of the calibration point is adjusted, thereby improving the accuracy of the massage action, and the force adaptive user experience is better. In addition, when the customer adjusts the sitting posture, it can also be adaptively adjusted according to the adjusted sitting posture to keep the body feeling consistent.

The invention discloses a nitrocellulose varnish and a preparation method thereof. The raw material formula of the nitrocellulose varnish contains two components, namely main agent and electrostatic thinner; by reasonably selecting materials and adjusting the proportions of the materials, the nitrocellulose varnish has the same performance requirement on hardness, luster, hand feeling, adhesive force and the like as the conventional product; and by adjusting the formulas of the main agent and the electrostatic thinner, the nitrocellulose varnish disclosed by the invention has good conductivity, volatile speed, anti-sagging property, elevation levelling property and other performances. The nitrocellulose varnish disclosed by the invention is suitable for the electrostatic spraying process;compared with the air spraying nitrocellulose varnish, the utilization rate of the paint can be greatly increased; the nitrocellulose varnish is suitable for special-shaped pieces such as guitars andornaments; and the cost of the paint is greatly reduced, the loss is reduced and the pollution to the environment is lowered.

The invention provides a waist belt and a preparation method thereof, and relates to a belt or the waist belt, and provides the waist belt which is formed in one step by an injection molding machine and has the advantages of difficult extension of belt holes, better bending and stretching resistance and difficult deformation and the preparation method thereof. The waist belt is a one-step molded belt made of artificial rubber, wherein the artificial rubber can be TPU, EVA, PVC and the like. The method comprises the following steps of: mixing an artificial rubber material and required pigment to obtain a mixed material; putting the mixed material into a material drying barrel for drying to obtain the dried mixed material for later use; fixing a die on the injection molding machine; setting each parameter of the injection molding machine for later use; putting the dried mixed material into a storage barrel of the injection molding machine to form a body through plasticizing, ejecting, cooling and other molding processes; and cleaning and airing the body to obtain the waist belt. The waist belt and a waist belt buckle can be assembled into a waist belt finished product.
