The invention relates to a combined treatment method for tinned copper waste and scrap and copper electrolyte. The tinned copper waste and scrap without covering on the surface are placed in the copper electrolyte to be treated, the tinned copper waste and scrap are leached, after the blue color of the copper electrolyte fades away, solid-liquid separation is performed to obtain a leach liquor, the detinned copper waste and scrap and main component are the replacement slag of sponge copper; air or oxygen is bubbled into the leach liquor, so that Sn2 + is oxidized to Sn4 +; and then the Ph value of the leach liquor is adjusted to 4.5-5, and the Sn4 + and impurity elements in the leach liquor are converted into a precipitate, and then the solid-liquid separation is performed to obtain purified liquid and filter residue. The tinned copper waste and scrap provided by the invention are taken from solid waste such as urban minerals or electronic waste, and can be directly used for purifyingthe copper electrolyte without special pretreatment, and the resources, environment and economic benefits are obvious. Through the same process, copper, tin, arsenic, antimony, bismuth, iron and otherelements in the copper electrolyte can be removed together, the process is simple, and the consumption is low.

When a user commands execution of a computer program to commence, a loader program 2 is first started. This loader program 2 reads an encrypted version of the computer program 6 and decrypts it using a public key. This generates an executable version of the computer program 9 which is written directly to the computer memory 8. When the loader program 2 has decrypted the whole of the computer program 9 it starts execution of the computer program 9 it has written into the computer memory 8 and terminates itself or is terminated by the computer program it started. The computer program 9 written into the computer memory 8 will be written into its own memory space and will have its own execution thread. The encryption used may be public key/private key encryption.

The timing controller outputs image data, a data control signal, a gate control signal and a switching signal. The data processor converts the image data into a data voltage based on the data control signal, and the switching circuit receives the data voltage and a common voltage having a predetermined period and outputs either the common voltage or the data voltage in response to the switching signal. The gate driver outputs a gate voltage in response to the gate control signal. The timing controller outputs the switching signal at a time point in a first half period of a transition period of the common voltage, and the switching circuit outputs the common voltage at the time point.

A method for detecting intensity saturation of a light sensor includes monitoring an electrical signal from a light sensor for detecting an intensity saturation condition of at least one pixel of the light sensor, converting the electrical signal to a digital signal, imposing a reserved bit combination on the digital signal indicating the intensity saturation condition of the pixel, and transmitting a control signal in response to the digital signal to compensate for the intensity saturation condition of the pixel. Alternatively stated, the method includes monitoring pixel data from an output of a light sensor to determine a number of pixels at saturation and a number of pixels near saturation, comparing the number of pixels at saturation to a predetermined first threshold number, comparing the number of pixels near saturation to a predetermined second threshold number, reprogramming the light sensor to adapt to more brightness if the number of pixels at saturation is above the first threshold number, and reprogramming the light sensor to adapt to less brightness if the number of pixels near saturation is below the second threshold number. An apparatus for detecting intensity saturation of a light sensor includes a saturation detector for detecting and measuring an intensity saturation condition of at least one pixel of a light sensor, the intensity saturation condition of the pixel being at saturation upon receiving light with an intensity above a predetermined level, the saturation detector emitting a digital signal with a reserved bit combination indicating the intensity saturation condition of the pixel, and a processor receiving and processing the digital signal from the saturation detector and transmitting a control signal in response to the digital signal to compensate for the intensity saturation condition of the pixel.

The present invention discloses a reused express delivery system and a document printing and reading method of a reused express delivery bag. When the reused express delivery bag is used for the first time, a code bar is pasted on a first tearing opening, and a bag mouth is pasted onto a bag body through a first pasting area to achieve seal of the reused express delivery bag. An addressee tears the first tearing opening after receiving the express delivery bag, and takes out a file from the bag. When the reused express delivery bag needs to be reused, a code bar is pasted on a second tearing opening, and the bag mouth is pasted onto the bag body through a second pasting area to achieve seal of the reused express delivery bag. The subsequent use can be done in the same manner, the tearing opening and the pasting area used every time are the lowest level of usable tearing opening and lowest level of usable pasting area. Through adoption of the scheme, repeated use of one express delivery bag can be achieved. A document printing system prints the code bar with a two-dimensional code or a three-dimensional code, thereby facilitating secrecy of the sent and received information. The scheme is suitable for the field of logistics and express.
