The invention provides an acoustic panel comprising a plurality of parallel-arranged elongated cavities, wherein each cavity has a first cavity wall and a second cavity wall tapering to a cavity back end and defining a cavity opening angle (γ) having a value in the range of 0°<γ<90°, wherein the first cavity wall and the second cavity wall comprise a light-reflective material, wherein each elongated cavity at the cavity back end of the elongated cavity accommodates a light source having a light exit surface, wherein the first cavity walls hide the light exit surfaces of the light sources when the acoustic panel is viewed along a normal to the acoustic panel, and wherein the acoustic panel further comprises sound reducing material.

A system for measuring microfluctuation of accommodation comprises a measuring module and a processing module. The measuring module includes at least one first sensing element attached to the area around an eye of a testee for measuring an EMG signal. The processing module is coupled with the measuring module for picking up a specific frequency range of the EMG signal as a measurement index of microfluctuation of accommodation, wherein the specific frequency range is between 0.1 Hz and 100 Hz. The system allows the testee to be tested in an open field of view and exempts the testee from experiencing fatigue in the muscle around the eyes. The system is compact and convenient to carry. A method for measuring microfluctuation of accommodation is also disclosed.

The present invention provides a projection device suitable for being installed on a vehicle and a control method thereof. The projection device includes a storage device, a projection module, a distance detection device and a control device. The storage device stores image data of at least one projection screen. The distance detection device measures the projection distance of the distance detection device to the projection plane. The control device is electrically connected to the storage device, the projection module and the distance detection device. The control device enables the projection module to project the above-mentioned at least one projection image and controls the brightness or size of the projection image corresponding to the projection distance, wherein the projection device is activated by opening the door, and the power of the projection device comes from the vehicle. The present invention can adjust the projection picture according to the projection distance to keep the picture size and brightness stable.

The invention discloses a fumigation inflatable thermotherapy device for auxiliary treatment of rheumatoid arthritis, which belongs to the technical field of medical equipment. The device mainly includes a wearing box, an inflatable hand fixing seat, a thermotherapy element, an intelligent control element, a fingertip traction element, and a power supply; The patient's finger is fumigated, breaking the limitation that the traditional fumigation and heat therapy device is inconvenient to carry, and the invention is also equipped with an arc-shaped inflatable air bag that fits the patient's finger to avoid the deviation of the finger, thereby affecting the fumigation effect. The elasticity of the fixed ring of the elastic airbag is variable, which can be used for patients of different physiques, and has strong practicability; through the traction of the patient's fingertips by the inflatable hand fixing seat, the patient's fingers are always in a straight state, avoiding the bending of the fingers and causing damage to the elasticity. The fitting degree of the airbag fixing ring is not enough, thereby affecting the effect of fumigation and heat therapy, and reducing the reliability of the device.

The invention discloses a fast detection device for high-precision connecting ring chamfering, which includes a base, a compression screw, a limit block, and a dial indicator. A conical protrusion is arranged on the side of the base, and a The oblique through hole, the oblique through hole runs through the conical protrusion and the positioning surface of the base, the pointer of the dial indicator is set in the oblique through hole, and the limit block is set in the oblique through hole on the positioning surface of the base At the opening, an arc-shaped notch is set on the limit block, and the arc-shaped notch is consistent with the outer surface of the pointer of the dial gauge to limit the position of the pointer. An oblique screw hole is set on the side of the base opposite to the positioning surface. , and communicate with the oblique through hole, and the pressing screw is arranged in the screw hole. The present invention can solve and realize the self-inspection of the operator during the processing and the detection of the chamfering size of the hole edge by the inspector, and the detection efficiency is high. , The device has high precision.

A container for the transport or storage of a bulk granular product is of generally cylindrical shape. Within the container is located a substantially conical exit hopper (13, 15, 17) and means (21) to convey the granular product from the exit hopper to the exterior of the container.

The invention relates to the field of thermoplastic resins, in particular to a device for laying thermoplastic resin products. The technical problem to be solved is to provide a thermoplastic resin product laying device.
