If possible, please provide only your telephone number to meet the needs of your local post office. If you are absent and cannot pick up items at your location in time, the post office may ask you to remind (in most cases, the postman will only give notice).
PS: We maintain a high degree of security and confidentiality of our customer's personnel information.
We mainly use EMS Express and Parcel Register Post for transportation. You can track EMS Express and your local post office. You can follow the post office at your local post office. Both require your signature to accept.
If you need a track number, please send us an email or leave us a message
We can also use other express transportation such as: UPS, DHL, FedEx, TNT etc. The cost will be higher. If you need the above services, you should contact us first.
Freight insurance is included in the S&H fee.
In general, EMS Express takes about 3 to 6 days depending on the location in the United States. Parcel post mail faster than EMS Express
If you do not use it at ordinary times, please contact us. We will first check its track number. If it does not work, we will send a paper tracking application to the USPS post office, which will take a few days to get a reply.

Laser ranging structure and operation process
The base part is a light emitter, which is your laser pointer. You also need a light receiver, a switch to control the light emitter, and a timer.The operation process is as follows: turn on the light transmitter to prompt the initial timing -- the light runs out, meets the reflective object and comes back -- is received by the light receiver with the timer interrupted timing. And then the calculation, light has a velocity, which you must know, let's say it's two seconds from declaration to reversal, what is the object going to be?Yeah, about 300,000 kilometers. Advantage the time into digital output, directly to the laser ranging is not demand DA conversion process of resolution can be as high as 65 ps, the conversion from the single measurement precision is 0.98 cm two stop channel can be measured with each measurement channel four pulse 1 MHZ continuous measurable data output rate QFN32 encapsulation, small volume, especially for hand-held laser range finder operating temperature planning: - 40 ° C to + 125 ° c. 8. Ultra-low power consumption.
Suppose you choose a measurement plan, take a measurement and a calibration every second, and when the power supply is 5V, the current consumption is only 3uA, which makes the tdc-gp2 particularly suitable for the hand-held rangefinder. In recent years, the high-speed direction of opening, the number of ships and water traffic density and the number of dangerous cargo loading increasing, collision of ships from time to time, the severe threat to ship flight safety and Marine ecological environment. It is imperative to develop an efficient collision avoidance system to protect the talents of moving ships.This system planning based on the high cost performance, according to start sea practice environment, use sophisticated laser measurement technology, the end of the collision avoidance system is the key technology of ranging technology is the key technology of ship collision avoidance system, this paper chooses laser ranging sensor and has two degrees of freedom yuntai, using high function of the single chip microcomputer control, the end of the horizontal and vertical direction of a full range of dynamic scanning, real-time independent monitoring policy boat and ships around the distance, the domain of ships and policies set by the distance of the ship arrived at a safe distance, sound and light alarm system alarm circuit is over,Prompt operators to adjust the ship's route in time, and conduct corresponding avoidance and other processing.
