An infrared camera is arranged to compensate for temperature variations of the camera by

Recording the output signal of each pixel of the detector during a shutter operation Using the recorded signal from each pixel to update a temperature offset map stored in the camera to ensure uniform signal levels at different camera temperatures, Said code means being arranged to perform the following steps during operation of the camera:

• • save at least a first temperature offset map during a first shutter operation at a first temperature and a second temperature offset map during a second shutter operation at a second temperature
  • fit the data from the at least first and second offset maps to a curve
  • using the curve to compensate for variations in signal output caused by temperature variations.

The invention relates to a green dust-fixing agent and a preparation method thereof. The green dust-fixing agent is prepared by using pregelatinized starch, dextrin, xanthan gum, cellulose ether derivatives, sucrose and water as raw materials with a proper weight ratio. A compounded mixture of pregelatinized starch, dextrin, xanthan gum and cellulose ether derivatives is used as a main binder, andsucrose is used as an auxiliary binder, the colloidal properties of the plant polysaccharide is fully utilized, a stable multi-point cross-linked network structure is formed between dust and soil particles, efficient capture and fixation of dust and soil can be realized, dust-fixing effect is good, long dust-fixing period is long, and the agent has certain erosion resistance; the product is green, safe, environmentally friendly, and non-polluting, and cannot not cause secondary pollution; the method has the advantages of simple construction and convenient operation, and can meet the needs ofdifferent dust-fixing environments such as building site construction, mine and industrial manufacturing; the preparation cost is low, the preparation process is simple, and the method are suitable for industrial production and scale promotion.

The invention relates to powdered lubricants for water based drilling fluids. Conventional liquid lubricants containing particularly divalent ions have the tendency to grease out. The powdered lubricants have excellent dispersion properties and hence do not grease out, when added to the drilling mud in the concentrations, preferably of the order of about 3% or less. The powdered lubricant is a combination of inert fillers with fatty acids that are essentially free from fatty acid esters and metal soaps and have organic acids containing C10-C24 alkyl groups fatty acids. The improved lubricating properties of the drilling muds result in greatly increased life of the rotary drilling bits and marked reduction in torque required to rotate the bit. Solid powdered additives compositions greatly reduce transportation costs and simplify the logistics and environmental concerns associated with shipping large volumes of liquids and overcome the pour point issues associated with liquid additives.

The disclosure discloses a positioning system, an indoor positioning method, a server and a storage medium, belonging to the technical field of positioning. The positioning system comprises a positioning server and n acquisition modules in a target area; wherein the target area comprises n cell grids, and the n cell grids and the n acquisition modules have a one-to-one correspondence; the acquisition module comprises a directional antenna and a wireless probe connected with the directional antenna, and each wireless probe is connected with the positioning server through a wired network and/ora wireless network. According to the embodiment of the disclosure, the target area is divided into n cell grids, and the acquisition module in each cell grid is used to collect wireless signals in thecell grid; because the environment in one cell grid is relatively simple, so the multipath transmission phenomenon is not easy to appear; therefore, the signal intensity of the wireless signal collected by the acquisition module is more accurate, so that the accuracy of the positioning based on the signal strength of the subsequent positioning server is ensured, and the positioning accuracy is greatly improved.

A home page advertising method is provided. The home page advertising method for transmitting home page data, including advertisement information, from a server to a client computer, wherein the server computer and client computers are interconnected through a network, includes the step of transmitting home page data, including one or more program codes that perform a predetermined layer function for displaying home page main content information and advertisement information on a home page screen in a separate window, wherein the program codes are written using a predetermined object-oriented programming language for implementing a predetermined multi-platform application within an operating system of the client computer. The home page advertising method reduces the complexity of a home page screen due to the presence of advertisement screens, while still effectively attracting the user's attention.

The invention discloses a production method of high-strength non-vibrated environmental-friendly smooth facing fabricated part mortar. Raw materials of the high-strength non-vibrated environmental-friendly smooth facing fabricated part mortar comprises limestone machine-made sand, limestone powder, early-strength sulphoaluminate cement, ordinary silicate cement, composite coupling agent, water reducing agent, dispersible emulsion powder, cellulose ether, starch ether, sodium tetraborate, lithium carbonate, antifoaming agent and high-strength fiber. According to the production method, the intrinsic defect of the crisp and hard performance of the mortar is overcome, the anti-cracking and anti-leakage performance of the mortar is improved, hollowing is reduced, the bonding force is improved,the mortar is more suitable for mechanical construction and has the advantages of low addition amount and high cost performance, and the rigidity of the mortar is improved; the problems are solved that the mortar is dry and is not easily scraped, the bonding strength is low, hollowing and falling phenomena are easily caused, the shrinkage amount is large, and the surface is easily cracked; the anti-freezing, anti-leakage and water-resistant performance of the mortar is improved, and the mortar has the advantages of being high in compressive strength, fracture resistance and leakage resistance,high in strength, non-vibrated, environmentally friendly and smooth.

A method of generating a linked client master mind map. Client actions and documents are linked to a client master mind map to generate a linked client master mind map. The linked client master mind map and a client relationship management program are reviewed and packaged.

The invention discloses a composite air purifying agent for purifying cigarette smoke. The composite air purifying agent is prepared by the steps: firstly, carrying out high temperature calcination activation of natural zeolite for 2-8 hours at the temperature of 400-800 DEG C, to obtain modified zeolite; placing the modified zeolite in a saturated potassium permanganate solution, immersing for 24 hours in a brown closed reactor at room temperature, after the impregnation is completed, taking out, vacuum-drying at the temperature of 80 DEG C, naturally cooling to obtain potassium permanganate-supported zeolite, and carrying out sealed light-shielding preservation; and evenly mixing 20-30 mesh activated carbon and the potassium permanganate-supported zeolite, to obtain the composite air purifying agent. The air purifying agent can effectively remove 99.9% of indoor cigarette smell and micro-particles, improves the purification effect of an air purifier, improves the indoor environment, avoids damage of secondhand smoke, and provides a healthy and comfortable environment for the family.
