Disclosed is a rehabilitation training bed for a stroke patient. The rehabilitation training bed comprises a bedstead, a support plate, a control mechanism and a driving motor set; the support plate is composed of a fixed part and a rotating part which are hinged to each other, one end of the support plate is provided with a head and neck support, the head and neck support is of an inflatable structure, and the outer surface of the head and neck support is provided with electrode sheets capable of releasing stimulating pulses; a power mechanism and a push-pull rod are arranged below the rotating part to achieve upward pushing and downward returning of the rotating part. The support plate is provided with forearm fixing plates and calf fixing plates, wherein electrode sheets are distributed on the surfaces of the forearm fixing plates and the surfaces of the calf fixing plates; the driving motor set can drive the upper limbs or the lower limbs of the patient to make left-right swing and forth-back extension movement through the forearm fixing plates and the calf fixing plates. The rehabilitation training bed for the stroke patient can automatically conduct sitting-up and lying-down training, constant changing of the functional positions of the upper limbs and the lower limbs and pulse massage stimulation on the stroke patient, so that muscle spasm and atrophy of the stroke patient who is bedridden for a long time are effectively avoided, and the rapid rehabilitation of the stroke patient is promoted.

The invention discloses a brake, a brake system and a vehicle. The brake comprises a drive motor, a conversion component, a wedge block component, brake pads and a brake disc, wherein the conversion component is suitable for converting rotation of the drive motor into rectilinear motion; the wedge block component comprises a first wedge block and a second wedge block, the wedge-shaped faces of thefirst wedge block and the second wedge block are oppositely arranged, and the first wedge block and the conversion component synchronously conduct rectilinear motion; the brake pads and the second wedge block synchronously move; and one part of the brake disc and the brake pads are oppositely arranged. Due to the adoption of the drive motor, a mechanical and electrical connecting mode makes the structure of the brake simple, mechanical connection is little, the weight and the size are small, a signal is transmitted quickly, a brake response is made quickly and sensitively, and quick braking can be achieved. In addition, the transmission efficiency is high due to the connecting mode, and energy can be effectively saved.

The invention discloses a device for measuring concentration of medical oxygen. The device comprises a cylindrical gas circuit connection pipe; the top part of a horizontally placed cylinder surface of the gas circuit connection pipe is a rectangular surface; the center of a rectangle is provided with a round hole, and is communicated with the gas circuit connection pipe; a buffer pipe is arranged on the rectangular surface at the top of the gas circuit connection pipe, and is communicated with the round hole; the buffer pipe is a vertically placed cylinder and is communicated with the gas circuit connection pipe; the top of the vertically placed buffer pipe is communicated with a gas concentration measurement pipe which is a cylinder; the lower part of the cylinder surface of the gas measurement pipe is a rectangular surface; the center of the rectangular surface at the lower part of the buffer pipe is provided with a round hole, and is communicated with the gas circuit connection pipe through the buffer pipe; the whole materials are prepared by adopting light aluminum alloy; the gas circuit connection pipe is used for being connected with the measured gas; the gas is ensured to disperse to the measurement pipe after the gas circuit connection pipe is connected with the gas, thus the gas concentration can be measured in the measurement pipe; an ultrasonic transmitter arranged in measurement pipe is used for transmitting and receiving ultrasonic signals which can be sent to a self-control circuit board through wires; signals are operated according to the different oxygen concentrations and different transmission speeds by the ultrasonic wave, and the signals are transmitted to a display after being processed, at this time, the corresponding oxygen concentration value can be observed on the display.

The invention relates to the field of semiconductor packaging, and discloses a chip-size wafer-level scale packaged dynamic random access memory and a manufacturing method therefor. The dynamic randomaccess memory comprises a stacked chip; the stacked chip comprises main chips and a control chip; and the main chips and the control chip are arranged in a stacked manner and the control chip is stacked between the two main chips. By enabling the control chip to be stacked between the two main chips of the stacked chip, particularly in the middle layer position of the stacked chip, the maximum connection distance between each main chip and the control chip can be obviously shortened, thereby effectively accelerating signal transfer between the chips; and meanwhile, the problems of signal noise and heating of the dynamic random access memory can be well controlled conveniently.

The invention discloses a manufacturing method of a photosensitive diode, comprising: firstly providing a substrate comprising a doping well; then forming a first doping region in the doping well; and then making use of an epitaxial process on the surface of the first doping region to form a conducting layer and meanwhile in-situ dopes the conducting layer to form a second doping region on the surface thereof. The manufacturing method of the photosensitive diode of the invention is mostly characterized in avoiding that the lattice structure of the surface is injected by high dose doping agent to be destroyed in the craftwork, thereby effectively reducing a dark current value generated in the non-light state and improving the sensitivity of the photosensitive diode.

The invention discloses a miniaturized double-frequency microstrip array antenna, and belongs to the field of double-frequency microstrip array antennae. The miniaturized double-frequency microstrip array antenna is used in three forms, the miniaturized double-frequency microstrip array antenna is placed at a use position when the miniaturized double-frequency microstrip array antenna is just used, and when signal transmission needs to be enhanced, the miniaturized double-frequency microstrip array antenna can be used by taking down a movable base; at the moment, a rotary protective sleeve can be unfolded through a torsion spring arranged on the rotary protective sleeve, the dual-frequency microstrip array antenna module can be driven to be unfolded after the rotary protective sleeve is unfolded, and the dual-frequency microstrip array antenna module is completely unfolded in a second state used by the device, so that the signal transmission function is enhanced; and when the terrain is low and influences signal transmission, the movable base can be reversed and is in butt joint with a threaded groove formed in the bottom of the pressure-bearing chassis, at the moment, the movable base is in a third state, the height of the device can be increased, signal transmission can be enhanced, the three states can be adjusted according to the use requirements of the device, and the use requirements of the device are met.
