As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0040] The present application provides a three-dimensional scanning system, Figure 1 As shown in the structural block diagram of the three-dimensional scanning system of an embodiment of the present application, the system comprises a master module 10, a power supply module 20, a temperature detection module 30 and a scanning device 40. Figure 1 The temperature detection module 30 is connected with the master module 10 and the power supply module 20 respectively, and is used for collecting first temperature information of the power supply module 20 and sending the first temperature information to the master module 10.

[0041] The master module 10 is connected with the power supply module 20 and the scanning device 40 respectively, and is used for adjusting performance parameters of the scanning device 40 according to a comparison result of the first temperature information and a preset temperature threshold.

[0042]

[0043] ​Specifically, the three-dimensional scanning system comprises a main control module 10, a power supply module 20 and a scanning device 40, the main control module 10 is connected with the scanning device 40 and the power supply module 20, is used for receiving image data collected by the scanning device 40, and provides power supply for the main control module 10 through the power supply module 20, such as using lithium battery for power supply and the like.

[0044] In order to protect the power supply module 20 of the equipment, in the three-dimensional scanning system, a temperature detection module 30 is arranged, which is connected with the main control module 10 and the power supply module 20 respectively, and the temperature detection module 30 is a digital temperature sensor or an analog temperature sensor. Among them, the temperature detection module 30 can be connected with the power supply module 20 in different installation modes, the temperature detection module 30 is arranged on the surface of the power supply battery 21 in the power supply module 20, the first temperature information of the surface of the power supply battery 21 is collected in real time through the temperature detection module 30, and the first temperature information is sent to the main control module 10; or the temperature detection module 30 is arranged at a target position in the power supply module 20, for example, arranged on the circuit board of the boost circuit module 22 connected with the power supply battery 21, the target position is close to the power supply battery 21 in the power supply module 20, and the temperature difference between the target position and the surface of the power supply battery 21 is relatively stable, the first temperature information of the target position is collected in real time through the temperature detection module 30, and the first temperature information is sent to the main control module 10.

[0045] Further, when the main control module 10 receives the first temperature information, the first temperature information and the preset temperature threshold are compared, when the first temperature information exceeds the preset temperature threshold, the performance parameters of the scanning device 40 are adjusted, and at the same time the main control module 10 sends an alarm command.

[0046] Among them, adjusting the performance parameters includes but is not limited to reducing the processing frame rate of the image sensor 41 in the scanning device 40, the light emitting power of the light compensator 43 and the light emitting power of the laser 42, or reducing the signal transmission rate of the wireless network module 50, reducing the performance of the main control module 10 itself and the like, the embodiment can select multiple ways to adjust synchronously, or can be adjusted according to the priority of each adjustment mode, so as to reduce the discharge current of the power supply module 20, so that the heat generated by the power supply module 20 during discharging is correspondingly reduced, so as to reduce the temperature of the power supply module 20, and avoid that the temperature of the power supply module 20 exceeds the preset temperature threshold. If all the performance parameters are adjusted, with the decrease of the battery capacity, the temperature of the power supply module 20 exceeds the preset temperature threshold, and the duration that the temperature of the power supply module 20 exceeds the preset temperature threshold reaches the preset time length, the system is forced to shut down.

[0047] It should be noted that, corresponding to the installation mode of the temperature detection module 30, if the temperature detection module 30 is arranged on the surface of the power supply battery 21 in the power supply module 20, the preset temperature threshold is the maximum safe working temperature of the power supply battery 21, and if the temperature detection module 30 is arranged at the target position in the power supply module 20, the temperature on the circuit board of the current boost circuit module 22 is obtained as the preset temperature threshold in the case that the power supply battery 21 reaches the maximum safe working temperature.

[0048] When the three-dimensional scanner works in a high-temperature environment, due to the structure sealing of the three-dimensional scanner, the temperature of the lithium battery for power supply inside the three-dimensional scanner will continuously rise. If the battery temperature exceeds the working temperature of the battery, it will affect the normal work of the three-dimensional scanner, and there is a great safety hazard. The prior art lacks temperature protection for the battery of the device, and problems such as abnormal work of the three-dimensional scanner are prone to occur.

[0049] Compared with the prior art, the three-dimensional scanning system of the present application is provided with a main control module 10, a power supply module 20, a temperature detection module 30 and a scanning device 40. The temperature detection module 30 is connected with the main control module 10 and the power supply module 20 respectively, and is used to collect the first temperature information of the power supply module 20 and send the first temperature information to the main control module 10. The main control module 10 is connected with the power supply module 20 and the scanning device 40 respectively, and is used to adjust the performance parameters of the scanning device 40 according to the comparison result of the first temperature information and the preset temperature threshold. Based on this, the temperature of the power supply module 20 is detected in real time by the temperature detection module 30. When the temperature of the power supply module 20 exceeds the threshold, the performance parameters of the scanning device 40 are adjusted in time by the main control module 10, so as to reduce the discharge current of the power supply module 20, thereby reducing the heat generated by the power supply module 20, achieving the effect of reducing the temperature, solving the problem of lacking temperature protection for the battery of the device, realizing the temperature protection for the battery of the device, and improving the stability and safety of the system.

[0050] In some embodiments, the power supply module 20 includes a power supply battery 21; the temperature detection module 30 is arranged on the surface of the power supply battery 21.

[0051] The temperature detection module 30 is used to collect the first temperature information of the power supply battery 21 and send the first temperature information to the main control module 10.

[0052] Specifically, in the case that the power supply module 20 includes a power supply battery 21, the temperature detection module 30 is arranged on the surface of the power supply battery 21, so that the temperature detection module 30 can directly collect the first temperature information on the surface of the power supply battery 21. The temperature detection module 30 is a digital temperature sensor or an analog temperature sensor. For example, the temperature sensor is fixed on the surface of the lithium battery by using high-temperature glue fixation, high-temperature adhesive tape fixation and the like, and the surface of the lithium battery is in good contact with the temperature sensor by applying heat-conducting silicone grease.

[0053] Furthermore, the measured first temperature information of the surface of the power supply battery is sent to the main control module 10, which determines whether the first temperature information of the surface of the power supply battery 21 reaches the preset temperature threshold, thereby realizing real-time monitoring of the temperature of the power supply battery 21.

[0054] In this embodiment, the temperature detection module 30 is placed on the surface of the power supply battery 21 in the power supply module 20, and the temperature detection module 30 collects the first temperature information of the power supply battery 21 and sends the first temperature information to the main control module 10, thereby obtaining the temperature of the battery surface, which facilitates accurate analysis of whether the battery temperature has reached the preset temperature threshold.

[0055] In some embodiments, the power supply module 20 includes a power supply battery 21 and a boost circuit module 22; the temperature detection module 30 is connected to the boost circuit module 22.

[0056] The boost circuit module 22 is connected to the power supply battery 21 and the main control module 10 respectively, and is used to boost the voltage of the power supply battery 21 to supply power to the system.

[0057] Temperature detection module 30 is used to collect the first temperature information of boost circuit module 22 and send the first temperature information to main control module 10.

[0058] In this embodiment, the temperature detection module 30 is placed at a target location in the power supply module 20, for example, on the circuit board of the boost circuit module 22 connected to the power supply battery 21. The target location is close to the power supply battery 21 in the power supply module 20, and the temperature difference between the target location and the surface of the power supply battery 21 is relatively stable.

[0059] Specifically, such as Figure 2 As shown, the power supply module 20 includes a power supply battery 21 and a boost circuit module 22. The boost circuit module 22 is connected to both the power supply battery 21 and the main control module 10, and is used to boost the voltage of the power supply battery 21 to supply power to the system. A temperature detection module 30 is installed on the circuit board of the boost circuit module 22 connected to the power supply battery 21. The circuit board of the boost circuit module 22 is close to the power supply battery 21 in the power supply module 20, and the temperature difference between the circuit board and the surface of the power supply battery 21 is relatively stable. The temperature detection module 30 collects the first temperature information on the circuit board of the boost circuit module 22 and sends the first temperature information to the main control module 10. The main control module 10 determines whether the first temperature information has reached a preset temperature threshold. In this embodiment, when the power supply battery 21 reaches its maximum safe operating temperature, the current temperature on the circuit board of the boost circuit module 22 is obtained as the preset temperature threshold.

[0060] It should be noted that since the battery level is closely related to its operating current, when the battery level is high, the operating current is relatively low, and the heat generated is also low. However, when the battery level decreases, the operating current increases, leading to an increase in heat generation, and the initial temperature reading may eventually reach the preset temperature threshold. Therefore, after replacing the system's power supply battery 21, the initial temperature reading will not quickly reach the preset temperature threshold and will still be applicable to the temperature monitoring method in this embodiment.

[0061] Furthermore, if, after all performance parameters have been adjusted, the temperature of the power supply module 20 exceeds the preset temperature threshold as the battery charge decreases, and the duration of the temperature exceeding the preset temperature threshold reaches the preset duration, then the boost circuit module 22 will be shut down via the enable signal of the boost circuit module 22, causing the system to automatically shut down.

[0062] In this embodiment, the power supply module 20 is equipped with a power supply battery 21 and a boost circuit module 22. The boost circuit module 22 is connected to the power supply battery 21 and the main control module 10, respectively, and is used to boost the voltage of the power supply battery 21 to supply power to the system. The temperature detection module 30 is connected to the boost circuit module 22 to collect the first temperature information of the boost circuit module 22 and send the first temperature information to the main control module 10, thereby obtaining the temperature on the circuit board of the boost circuit module 22 in real time. Since the temperature difference between the circuit board temperature of the boost circuit module 22 and the surface of the power supply battery 21 is relatively stable, it is possible to accurately determine whether the battery temperature has reached the preset temperature threshold based on the circuit board temperature of the boost circuit module 22.

[0063] In some embodiments, the boost circuit module 22 includes a reverse connection protection circuit; the reverse connection protection circuit is connected to the power supply module 20.

[0064] It should be noted that the main control module 10 is powered by the power supply module 20, which can be powered by batteries such as lithium batteries. The batteries usually have a protection board to protect them from damage such as overcharging, over-discharging, short circuit and overcurrent. However, the battery protection board does not have reverse connection protection function.

[0065] Specifically, this embodiment includes a reverse connection protection circuit in the boost circuit module 22, which is connected to the power supply module 20 to prevent damage to the circuit when the battery polarity is reversed. The reverse connection protection circuit can be implemented through physical isolation or electronic control to ensure that current flows only in the correct direction; examples include diode reverse connection protection circuits and MOSFET reverse connection protection circuits.

[0066] Through the embodiment, the reverse connection prevention circuit is arranged in the voltage boosting circuit module 22 and connected with the power supply module 20, so that damage to the circuit caused by reverse connection of the battery polarity is prevented, and the safety and stability of the power supply module 20 are improved.

[0067] In some embodiments, the scanning device 40 includes at least two image sensors 41, each of which is connected with the master module 10.

[0068] The master module 10 is configured to reduce the processing frame rate of the image sensor 41 when the first temperature information exceeds the preset temperature threshold.

[0069] In the embodiment, as shown in Figure 3 The scanning device 40 includes at least two image sensors 41, each of which is connected with the master module 10, and is configured to collect image data of the measured object during scanning and transmit the collected image data to the master module 10, such as transmitting the image data to the master module 10 through a low-voltage differential signaling (LVDS) communication line.

[0070] Specifically, when the master module 10 detects that the current first temperature information exceeds the preset temperature threshold, the processing frame rate of the image sensor 41 is reduced, and an alarm command is issued, and the first temperature information is continuously monitored. If the temperature of the power supply module 20 still reaches the preset temperature threshold after the processing frame rate of the image sensor 41 is reduced, the performance parameters of other devices in the scanning device 40 can be further adjusted, or the performance of the master module 10 itself can be reduced, so as to avoid the temperature of the power supply module 20 continuously reaching the preset temperature threshold.

[0071] It should be noted that reducing the processing frame rate of the image sensor 41 will not affect the scanning effect.

[0072] Through the embodiment, the scanning device 40 includes at least two image sensors 41, and the master module 10 reduces the processing frame rate of the image sensor 41 when the first temperature information exceeds the preset temperature threshold, so that the discharge current of the power supply module 20 is reduced, and the heat generated by the power supply module 20 during discharge is correspondingly reduced, thereby achieving the effect of reducing the temperature of the power supply module 20.

[0073] In some embodiments, the system further includes a wireless network module 50, which is connected with the master module 10.

[0074] The master module 10 is configured to reduce the signal transmission rate of the wireless network module 50 when the processing frame rate of the image sensor 41 is reduced.

[0075] In this embodiment, the system is provided with a wireless network module 50, such as a Universal Serial Bus (USB) wireless network card. The wireless network module 50 is connected to the main control module 10 and is used to transmit the data information of the main control module 10 to the terminal device 60 for three-dimensional reconstruction through wireless access point (WIFI AP) mode or wireless direct connection (WIFIDirect) to obtain the three-dimensional data corresponding to the measured object.

[0076] Specifically, such as Figure 4 As shown, due to the high power of the wireless network module 50, when the main control module 10 detects that the current first temperature information exceeds the preset temperature threshold, it reduces the processing frame rate of the image sensor 41, simultaneously reduces the signal transmission rate of the wireless network module 50, and issues an alarm command. Afterwards, it continuously monitors whether the first temperature information decreases. If, after reducing the processing frame rate of the image sensor 41, the temperature of the power supply module 20 still reaches the preset temperature threshold, it can further adjust the performance parameters of other devices in the scanning device 40, or reduce the performance of the main control module 10 itself, to prevent the power supply module temperature from continuously reaching the preset temperature threshold.

[0077] It should be noted that reducing the processing frame rate of the image sensor 41 and reducing the signal transmission rate of the wireless network module 50 will not affect the scanning effect.

[0078] In this embodiment, when the system includes a wireless network module 50, if the current first temperature information is detected to exceed a preset temperature threshold, the processing frame rate of the image sensor 41 is reduced, and the signal transmission rate of the wireless network module 50 is reduced simultaneously, thereby improving the temperature protection performance of the system.

[0079] In some embodiments, the system further includes a terminal device 60; the terminal device 60 is connected to the main control module 10 via a wireless network module 50.

[0080] Terminal device 60 is used to obtain the first temperature information of power supply module 20 through wireless network module 50, and send a scanning command to main control module 10 when the first temperature information is detected to be less than the preset temperature threshold.

[0081] The main control module 10 is used to control the scanning device 40 to perform three-dimensional scanning according to the scanning instructions.

[0082] In this embodiment, the system is equipped with a terminal device 60, such as a personal computer. The terminal device 60 is connected to the main control module 10 through a wireless network module 50. It is used to receive data information of the object under test, perform three-dimensional reconstruction on the data information of the object under test, obtain three-dimensional data of the object under test, and can also receive alarm commands issued by the main control module 10.

[0083] Specifically, as shown in Figure 4 The terminal device 60 acquires the first temperature information of the power supply module 20 from the host module 10 in real time through the wireless network module 50, and determines whether the first temperature information exceeds the preset temperature threshold. When it is detected that the first temperature information does not exceed the preset temperature threshold, a scanning instruction is sent to the host module 10. When the host module 10 receives the scanning instruction, the scanning device 40 is controlled to perform three-dimensional scanning on the measured object according to the scanning instruction. If it is detected that the first temperature information continuously exceeds the preset temperature threshold, a shutdown command is sent to the host module to instruct the host module to control the scanning device 40 to stop scanning.

[0084] Through the embodiment, the terminal device 60 acquires the first temperature information of the power supply module 20 through the wireless network module 50. When it is detected that the first temperature information does not exceed the preset temperature threshold, a scanning instruction is sent to the host module 10. The host module 10 controls the scanning device 40 to perform three-dimensional scanning according to the scanning instruction, so as to control whether to start the scanning work based on the temperature information of the power supply module 20, thereby avoiding that the scanning device 40 is still in the scanning state when the temperature of the power supply module 20 is too high, and ensuring the safety of the system.

[0085] In some embodiments, the scanning device 40 further includes a laser 42;

[0086] The temperature detection module 30 is configured to acquire second temperature information of the power supply module 20 after reducing the processing frame rate of the image sensor 41, and send the second temperature information to the host module 10.

[0087] The host module 10 is configured to reduce the light emitting power of the laser 42 when the second temperature information exceeds the preset temperature threshold.

[0088] Specifically, as shown in Figure 3 In the embodiment, the scanning device 40 includes a laser 42, and the laser 42 is configured to project a laser pattern to the surface of the measured object. After reducing the processing frame rate of the image sensor 41 and the signal transmission rate of the wireless network module 50, the temperature of the power supply module 20 is continuously monitored to obtain second temperature information. If it is detected that the second temperature information exceeds the preset temperature threshold, the light emitting power of the laser 42 is reduced by the host module 10.

[0089] The laser 42 usually controls its brightness by pulse width, and the light emitting power of the laser 42 can be reduced by reducing the duty cycle of the laser 42.

[0090] By the embodiment, after the processing frame rate of the image sensor 41 is reduced, the second temperature information of the power supply module 20 is collected by the temperature detection module 30, the second temperature information is sent to the main control module 10, and when the second temperature information exceeds the preset temperature threshold, the light emitting power of the laser 42 is reduced, so that the temperature of the power supply module 20 can be continuously monitored when the battery power is continuously reduced, and other device parameters in the scanning device 40 are adjusted in time, and complete battery temperature protection is realized.

[0091] In some embodiments, the scanning device 40 further comprises a light compensator 43.

[0092] The temperature detection module 30 is configured to collect second temperature information of the power supply module 20 after the processing frame rate of the image sensor 41 is reduced, and send the second temperature information to the main control module 10.

[0093] The main control module 10 is configured to reduce the light emitting power of the light compensator 43 when the second temperature information exceeds the preset temperature threshold.

[0094] Specifically, as shown in FIG. 4, the scanning device 40 in the embodiment comprises the light compensator 43, which can be multiple and is used for light compensation when collecting image data of the measured object. Figure 3 After the processing frame rate of the image sensor 41 is reduced and the signal transmission rate of the wireless network module 50 is reduced, the temperature of the power supply module 20 is continuously monitored to obtain second temperature information, and if it is detected that the second temperature information exceeds the preset temperature threshold, the light emitting power of the light compensator 43 is reduced by the main control module 10.

[0095] The light compensator 43 usually controls its brightness by pulse width, and the light emitting power of the light compensator 43 can be reduced by reducing the duty cycle of the light compensator 43.

[0096] By the embodiment, after the processing frame rate of the image sensor 41 is reduced, the second temperature information of the power supply module 20 is collected by the temperature detection module 30, the second temperature information is sent to the main control module 10, and when the second temperature information exceeds the preset temperature threshold, the light emitting power of the laser 42 is reduced, so that the temperature of the power supply module 20 can be continuously monitored when the battery power is continuously reduced, and other device parameters in the scanning device 40 are adjusted in time, and complete battery temperature protection is realized.

[0097] In some embodiments, the main control module 10 is further configured to control the system to shut down when the first temperature information exceeds the preset temperature threshold for a first duration greater than a preset duration threshold; and / or,

[0098] When all the performance parameters are adjusted, the main control module 10 is further configured to control the system to shut down when the temperature information of the power supply module 20 exceeds the preset temperature threshold again for a second duration greater than the preset duration threshold.

[0099] Specifically, the main control module 10 monitors whether the first temperature information exceeds the preset temperature threshold for a first duration greater than the preset duration threshold. If the first temperature information exceeds the preset temperature threshold for a first duration greater than the preset duration threshold, the system is shut down.

[0100] Further, when all the performance parameters are adjusted, i.e., the processing frame rate of the image sensor 41, the luminous power of the laser 42 and the light compensator 43, and the signal transmission rate of the wireless network module 50 are adjusted, the temperature of the power supply module 20 is usually lower than the preset temperature threshold. However, as the battery power decreases, the temperature of the power supply module 20 may exceed the preset temperature threshold again. If the main control module 10 detects that the temperature of the power supply module 20 exceeds the preset temperature threshold again for a second duration reaching the preset duration threshold, the system is forcibly shut down to ensure the safety of the system.

[0101] It should be noted that when the system is shut down, the enable signal of the boost circuit module 22 in the control system can be used to turn off the boost circuit module 22, so that the system has no input power supply, and the system is automatically shut down. The above two control methods can be selected and applied according to the actual scene, so as to prevent the temperature of the power supply module 20 from exceeding the preset temperature threshold for a long time.

[0102] Through the embodiment, when the first temperature information exceeds the preset temperature threshold for a first duration greater than the preset duration threshold, the system is shut down. When all the performance parameters are adjusted, and the temperature information of the power supply module 20 exceeds the preset temperature threshold again for a second duration greater than the preset duration threshold, the system is shut down. In this way, the duration for which the temperature of the power supply module 20 exceeds the preset temperature threshold is prevented from being too long, and the safety performance of the system is improved.

[0103] In some embodiments, the temperature detection module 30 is a digital temperature sensor or an analog temperature sensor.

[0104] Specifically, the temperature detection module 30 is a digital temperature sensor or an analog temperature sensor. When a digital temperature sensor is used, the temperature value of the power supply module 20 is collected in real time and transmitted to the main control module 10. Alternatively, an analog temperature sensor such as a negative temperature coefficient thermistor is used to output a real-time analog temperature signal, and the main control module 10 calculates the temperature value corresponding to the analog temperature signal to obtain the current temperature of the power supply module 20.

[0105] By this embodiment, the digital temperature sensor or the analog temperature sensor is used as the temperature detection module 30 to accurately obtain the real-time temperature of the power supply module 20.

[0106] The embodiment is described and explained below by preferred embodiments.

[0107] Figure 5 is a schematic diagram of a three-dimensional scanning system provided by an embodiment of the present application, as shown in the figure, the system comprises a master control module 10, a power supply module 20, a temperature detection module 30, a scanning device 40, a wireless network module 50 and a terminal device 60; wherein the power supply module 20 comprises a power supply battery 21, and the scanning device 40 comprises two image sensors 41, a laser 42 and a light compensator 43. Figure 5

[0108] Specifically, the master control module 10 is connected with the scanning device 40 and the power supply module 20, used for receiving the image data collected by the scanning device 40, and providing power supply for the master control module 10 through the power supply module 20, and the temperature detection module 30 is connected with the master control module 10 and the power supply module 20 respectively, the temperature detection module 30 is a digital temperature sensor or an analog temperature sensor, the temperature detection module 30 is arranged on the surface of the power supply battery 21 in the power supply module 20, the first temperature information on the surface of the power supply battery 21 is collected by the temperature detection module 30 in real time, and the first temperature information is sent to the master control module 10.

[0109] When the master control module 10 receives the first temperature information, the first temperature information is compared with a preset temperature threshold, when the first temperature information exceeds the preset temperature threshold, the processing frame rate of the image sensor 41 in the scanning device 40 is reduced, the signal transmission rate of the wireless network module 50 is reduced synchronously, and an alarm command is sent to the terminal device 60, so as to reduce the discharge current of the power supply module 20, and the heat generated by the power supply module 20 during discharging is correspondingly reduced, so as to achieve the effect of reducing the temperature of the power supply module 20.

[0110] Further, the temperature of the power supply module 20 is continuously monitored to obtain second temperature information, if it is detected that the second temperature information exceeds the preset temperature threshold, the light emitting power of the laser 42 and / or the light compensator 43 is reduced by the master control module 10, so as to realize the battery temperature protection by adjusting other equipment parameters in the scanning device 40 in the process of continuously reducing the battery power. Wherein the laser 42 and the light compensator 43 usually control their brightness by pulse width, and the light emitting power of the laser 42 and the light compensator 43 can be reduced by reducing the duty cycle of the laser 42 and the light compensator 43.

[0111] ​After the performance parameter adjustment of all devices is completed, as the battery power decreases, the power supply module 20 temperature exceeds the preset temperature threshold, and the duration of the power supply module 20 temperature exceeding the preset temperature threshold reaches the preset time length, the system is forced to shut down to ensure the safety of the system.

[0112] Through the embodiment, the first temperature information of the surface of the power supply battery 21 is collected in real time by the temperature detection module 30, the first temperature information is sent to the main control module 10, when the main control module 10 detects that the first temperature information exceeds the preset temperature threshold, the processing frame rate of the image sensor 41 in the scanning device 40 and the signal transmission rate of the wireless network module 50 are reduced. As the battery power decreases, the power supply module 20 temperature is continuously monitored, when the power supply module 20 temperature exceeds the preset temperature threshold again, other device parameters in the scanning device 40 are adjusted, and in the case that the duration of the power supply module 20 temperature exceeding the preset temperature threshold reaches the preset time length, the system is shut down, the battery temperature protection is realized, and the safety performance of the system is improved.

It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
