An apparatus and method of controlling a repetitive motion linear actuator (RMLA) accepts a minimum repetition rate and a commanded repetition rate. If the commanded rate is greater than the minimum rate, the RMLA automatically operates in a speed scaling mode by continuously applying the cycles and scaling the cycle length to provide the commanded rate. If the commanded rate is less than the minimum rate, the RMLA automatically operates in a dwell mode by fixing the cycle length and discontinuously applying the cycles, while adjusting a separation between the cycles to provide the commanded rate. In dwell mode, the cycle length can be equal to its maximum allowed value T<max>, or can equal a desired value less than T<max>. The cycle can have any profile shape, such as a sinusoidal shape or a shape that includes periods of deceleration and acceleration separated by constant speed periods therebetween.

A photovoltaic module (300) is described comprising:- a substrate (320) for mechanical support and electrical connection comprising a sheet (322) of electrically insulating plastic material and at least one layer (324) of electrically conducting metallic material suitably configured, said substrate (320) being located on the back of the photovoltaic module (300);- a plurality of photovoltaic cells (310) mechanically fixed to the substrate (320) and electrically connected to each other through the layer (324) of the substrate (320) so as to form one or more strings of cells, said cells (310) being located on the front side of the photovoltaic module (200) adjacent to each other and adjacent to the substrate (320);the layer (324) is configured such that adjacent cells of said plurality of cells (310) are electrically connected two by two;the photovoltaic module further comprises a plurality of bypass diodes electrically connected to the cells (310).

An electric toothbrush device with a built-in shrapnel assembly includes a toothbrush head, a brush assembly and an electric motor. A built-in shrapnel assembly is disposed in the cavity, and the built-in shrapnel assembly is disposed to abut against the drive shaft. The built-in shrapnel assembly includes an arch-shaped protrusion arching towards the drive shaft. A side of the drive shaft facing the arch-shaped shrapnel assembly defines a tooth groove matching the arch-shaped protrusion, the drive shaft presses against the arch-shaped protrusion, to cause the arch-shaped protrusion to undergo an elastic deformation, to thereby securely fix the drive shaft in the cavity. The electric toothbrush head device has the advantages of strong practicality, high stability, and long-term use without deformation, by providing the shrapnel assembly inside to increase the clamping effect.

An insulin pump control method and apparatus, an artificial pancreatic closed-loop system, and a storage medium are provided. The method includes: acquiring first monitoring data of a target object, obtaining an injection dosage of a first injection according to a target model and the first monitoring data, and injecting the target object based on the injection dosage of the first injection. The target model is adjusted based on total dosages corresponding to historical prediction failures.

Apparatus (10; 10') for the heat treatment of materials (M) comprising both a reaction chamber (11) configured to receive materials (M) to be treated and provided with an advance device (15) configured to make said materials (M) fed by at least one feed duct (16) advance toward at least one outlet duct (17) for the disposal of the solid component resulting from the pyrolysis of the treated materials (M), and also a furnace (12) having a containing chamber (13) which at least partly encloses said reaction chamber (11) and is configured to heat the reaction chamber (11) and said materials (M) present therein by thermal conduction, generating gaseous substances (S) therein. The advance device (15) comprises a helical structure formed by a plurality of turns (20), and a central shaft (21), internally hollow so that it can receive said gaseous substances (S) inside it and rotatable around a central axis (AC) so as to make said turns (20) rotate, thus making said materials (M) advance.

The invention provides a reagent disc control device which uses a combined rotary wheel to control an inner rod and an outer rod in a locking mechanism to move. By improving the structure of the combined rotary wheel, the locking mechanism can lock and release a reagent disc more stably and smoothly. Even if the rotary wheel is in direct contact with the locking mechanism, the locking mechanism will not shake. In this way, the reagent disc control device is simpler in structure and higher in response speed, and ensures the operating stability of the locking mechanism, thereby ensuring the accuracy of fluorescence detection reading in the reagent disc. Moreover, the reagent disc control device can complete more precise and complicated actions, so that the locking mechanism can switch between an initial state and a working state flexibly. The locking mechanism is allowed to return to the initial state when it is not working, and to enter the working state when it needs to work. Springs in the locking mechanism do not need to be in a compressed state for a long time, and can be reused many times, thereby prolonging the service life and lowering the cost.

Provided in the present application is a pectin gel and a preparation method thereof, the pectin gel including a pectin and a fat-soluble substance, in which a weight average molar weight of the pectin is in a range of 5.0× 10^4 to 6.0× 10^5 Da, a polymer dispersion index thereof is in a range of 1 to 6; in the structural domains of the pectin, HG > 30 mol% and RG-1 ≤ 35 mol%; HG is homogalacturonan and RG-1 is rhamnogalacturonan type I. The pectin gel has high emulsion stability before forming, so the pectin gel after forming has good texture stability, and the amount of water and oil separation is low, and the taste of the pectin gel is good.
