referring to fig1 , the universal connection recognition system 100 in an embodiment of the present invention includes a universal connector 10 , a pin recognition module 20 , and a detection module 40 . as shown in fig1 , the universal connector 10 is composed of a plurality of detection pins 11 . each detection pin 11 can be a gold finger or a pogo pin . the number of the detection pins 11 and the shape of each detection pin 11 depend on the intended applications or production requirements ; the present invention does not have special limitations in this regard . the detection pins 11 are configured mainly for electrical connection with a plurality of external terminals 50 to be detected . more specifically , each to - be - detected terminal 50 is to be electrically connected with at least one detection pin 11 . in other words , the thickness or width of each detection pin 11 can be less than that of each to - be - detected terminal 50 . the to - be - detected terminals 50 can be the terminals of a detection instrument or device of any brand or configuration . for example , the to - be - detected terminals 50 can be the connection terminals of a blood glucose meter of any brand or configuration . in addition , the detection pins 11 can be arranged in a two - dimensional ( 2d ) array , as shown in fig8 a , or a three - dimensional ( 3d ) array , as shown in fig8 b . proper arrangement of the detection pins 11 not only facilitates signal communication , but also may increase the area of contact between the detection pins 11 and the to - be - detected terminals 50 . when the to - be - detected terminals 50 are relatively thick or are arranged over a relatively large area , arranging the detection pins 11 in a 3d array helps provide error - free contact . fig9 shows how the detection pins 11 , arranged in a 3d array , are used to detect the to - be - detected terminals 50 . whether or not the contact portions of the to - be - detected terminals 50 have a uniform thickness or height , the 3d array of detection pins 11 can detect the to - be - detected terminals 50 without error . fig1 shows how the detection pins 11 , arranged on two 3d arrays above and below the to - be - detected terminals 50 , are used to detect the to - be - detected terminals 50 formed on upper and lower surfaces of a substrate . referring back to fig1 , the pin recognition module 20 is configured to send an identifying signal 91 to one of the detection pins 11 , read the signal of each of the other detection pins 11 , and then identify and group the detection pins 11 to form a corresponding pin combination 30 . the identifying signal 91 can be a digital signal . in one embodiment of the present invention , the identifying signal 91 is a current signal such that , when several detection pins are in contact with the same to - be - detected terminal 50 and the current signal is sent to the to - be - detected terminal 50 via a specific one of those detection pins , the rest of the detection pins in contact with the to - be - detected terminal 50 each detect a corresponding current signal and are therefore classified as in the same group as that specific detection pin . the identifying signal 91 , however , is not necessarily a current signal , provided that the identifying signal 91 can be used to determine whether a plurality of detection pins are in contact with the same to - be - detected terminal . as demonstrated by the embodiment shown in fig1 , some detection pins 11 are classified as group a , some detection pins 11 are classified as group b , some detection pins 11 are classified as group c , some detection pins 11 are classified as group d , and some detection pins 11 are classified as group e . groups a through e define a corresponding pin combination 30 . when the to - be - detected terminals 50 are the connection terminals of a blood glucose meter of a certain brand and configuration , the corresponding pin combination 30 obtained by the foregoing identifying and grouping process includes a pin - grouping arrangement that matches the connection terminals perfectly . referring to fig3 , the pin recognition module 20 of the universal connection recognition system 100 may further include a digital signal generating unit 21 and a pin recognition unit 22 . the digital signal generating unit 21 is configured to generate and send out a digital signal while the pin recognition unit 22 is configured to identify and group the detection pins 11 . fig5 shows an embodiment of the recognition process s 100 performed by the pin recognition module 20 . as stated above with regard to the function of the pin recognition module 20 , the process s 100 may include : looking for any unclassified detection pin ( step s 101 ), sending a signal to one detection pin ( step s 102 ), detecting the other detection pins ( step s 103 ), grouping the detection pins ( step s 104 ), and establishing a corresponding pin combination ( step s 105 ). to look for any unclassified detection pin ( step s 101 ), the universal connection recognition system 100 reads pin - corresponding data to identify any unclassified detection pin 11 . the pin - corresponding data can be stored in the universal connection recognition system 100 or read in from an external source . to send a signal to one detection pin ( step s 102 ), the universal connection recognition system 100 sends an identifying signal 91 to one of the detection pins 11 . to detect the other detection pins ( step s 103 ), the universal connection recognition system 100 reads the signals sent by all the detection pins 11 except for the detection pin 11 to which the identifying signal 91 was sent . to group the detection pins ( step s 104 ), the universal connection recognition system 100 identifies and groups the detection pins 11 according to the signals read from all the detection pins 11 except for the detection pin 11 to which the identifying signal 91 was sent . to establish a corresponding pin combination ( step s 105 ), the universal connection recognition system 100 defines the identified and grouped detection pins 11 as a corresponding pin combination 30 . referring again to fig1 , the detection module 40 is configured to send a test signal 92 to the corresponding pin combination 30 and then receive and process a feedback signal 93 sent by the corresponding pin combination 30 in response to the test signal 92 . as shown in fig1 and fig7 , the test signal 92 sent by the detection module 40 can be an analog signal such as a voltage signal or a current signal . in fig7 , where the test signal 92 is a voltage signal by way of example , the test signal 92 of a certain voltage value is input to group a in the corresponding pin combination 30 , and then the voltage value of the feedback signal 93 detected from a group other than group a ( e . g ., group b ) is read . by calculating the difference between the input voltage value and the read voltage value , the impedance value between group a and group b is obtained . by the same token , the impedance value between each two groups can be obtained , thereby acquiring the impedance characteristics of the entire corresponding pin combination 30 , and hence of each two connection terminals of the corresponding blood glucose meter ( or other detection device ). referring to fig4 , the detection module 40 of the universal connection recognition system 100 may further include an analog signal generating unit 41 and an impedance detection unit 42 . the analog signal generating unit 41 is configured to generate and send out an analog signal , and the impedance detection unit 42 , to detect the impedance value between each two groups of detection pins and thereby obtain the impedance characteristics of the corresponding pin combination 30 and of the corresponding blood glucose meter ( or other detection device ). fig6 shows an embodiment of the detection process s 200 performed by the detection module 40 . as stated above with regard to the function of the detection module 40 , the detection process s 200 may include : inputting a voltage to a group of detection pins ( step s 201 ), reading a voltage value from another group of detection pins ( step s 202 ), and calculating or storing an impedance value between the two groups of detection pins ( step s 203 ). moreover , referring to fig2 , the universal connection recognition system 100 may further include a control unit 60 for controlling the operation of the pin recognition module 20 and of the detection module 40 . the control unit 60 can be a hardware device , software , firmware , or a combination of any two of the above . the control unit 60 may further include or connect with a storage element 62 for storing the data of blood glucose meters or other detection devices that have been connected to and detected by the system . when one of those blood glucose meters or detection devices is connected to the system again , the data corresponding to the blood glucose meter or detection device can be immediately retrieved from the storage element 62 and put to use . in a nutshell , the universal connector 10 , the pin recognition module 20 , the detection module 40 , and the control unit 60 are so designed that the universal connection recognition system 100 can be implemented at low cost without a complicated manufacturing process or costly production equipment , has a wide range of applications due to its compatibility with various detection instruments or devices , and features a learning function to ensure that the correct pin - grouping arrangement is automatically applied when a device is connected to the system again . the embodiments described above are intended only to demonstrate the technical concept and features of the present invention so as to enable a person skilled in the art to understand and implement the contents disclosed herein . it is understood that the disclosed embodiments are not to limit the scope of the present invention . therefore , all equivalent changes or modifications based on the concept of the present invention should be encompassed by the appended claims .
