在这一实施例中，无线装置100可以是如智能手机、平板电脑、笔记本电脑或任何其他便携式装置的无线装置，以及该无线装置100包括应用处理器110、无线网络模块120以及存储单元130。
In this embodiment, the wireless device 100 may be an electronic device such as a smartphone, a tablet, a notebook or any other portable device, and the wireless device 100 comprises an application processor 110, a wireless network module 120 and a storage unit.
该应用处理器110用于执行在该无线装置100的系统上运行的应用。
The application processor 110 is arranged to execute applications running on a system of the wireless device 100.
该无线网络模块120可包括WIFI模块、蓝牙模块与/或能够连接到互联网或者其他电子装置的其他合适的网络电路。
The wireless network module 120 may comprise a Wi-Fi module, a Bluetooth module and/or any other suitable network circuit capable of connecting to Internet or other electronic devices.

The storage unit 130 may comprise a plurality of different storage devices, and stores data related to the application processor 110 and the wireless network module 120.
如图2所示，无线装置100构建与多个电子装置210、220以及230的链路。
As shown in FIG. 2, the wireless device 100 builds links with a plurality of electronic devices 210, 220 and 230.
在这一实施例中，无线装置100藉由使用蓝牙A2DP与电子装置210通信，无线装置100藉由使用第一WIFI信道与电子装置220通信，以及无线装置100与电子装置220属于基础服务集合(basic service set)BSS0，以及无线装置100藉由使用第二WIFI信道与电子装置230通信，以及无线装置100与电子装置230属于另一个基础服务集合BSS1。
In this embodiment, the wireless device 100 communicates with the electronic device 210 by using the Bluetooth A2DP; the wireless device 100 communicates with the electronic device 220 by using a first Wi-Fi channel, and the wireless device 100 and the electronic device 220 belong to a basic service set BSS 0; and the wireless device 100 communicates with the electronic device 230 by using a second Wi-Fi channel, and the wireless device 100 and the electronic device 230 another basic service set BSS 1.
在这一实施例中，因为蓝牙与WIFI信道使用2.4Hz工业科学医疗(ISM)频段，无线装置100使用TDD与FDD的混合模式来在保持性能的同时，与电子装置210、220以及230有效地通信。
In this embodiment, because the Bluetooth and the Wi-Fi channels use 2.4 GHz industrial scientific medical (ISM) band, the wireless device 100 uses a hybrid mode of TDD and FDD to efficiently communicate with the electronic devices 210, 220 and 230 while maintaining the performance.
图3示出了根据本发明一个实施例的在通信系统中使用的TDD模式以及FDD模式。
FIG. 3 shows the TDD mode and FDD mode used in the communication system according to one embodiment of the present invention.
在图3中，在TDD模式下使用无线装置100与电子装置210之间的蓝牙以及无线装置100与电子装置220(BSS0)之间的第一WIFI信道，以及在FDD模式下使用无线装置100与电子装置210之间的蓝牙以及无线装置100与电子装置230(BSS1)之间的第二WIFI信道。
In FIG. 3, the Bluetooth between the wireless device 100 and the electronic device 210 and the first Wi-Fi channel between the wireless device 100 and the electronic device 220 (BSS 0) are used under the TDD mode, and the Bluetooth between the wireless device 100 and the electronic device 210 and the second Wi-Fi channel between the wireless device 100 and the electronic device 230 (BSS 1) are used under the FDD mode.
具体来说，在图3中示出的第一期间中，无线装置100使用蓝牙与电子装置210通信，以及使用第二WIFI信道来与电子装置230(BSS1)通信，其中所选择的蓝牙信道与第二WIFI信道具有不同的频率。
In detail, during a first period shown in FIG. 3, the wireless device 100 uses the Bluetooth to communicate with the electronic device 210, and uses the second Wi-Fi channel to communicate with the electronic device 230 (BSS 1), where the selected Bluetooth channel and the second Wi-Fi channel have different frequencies.
在紧接着第一期间的第二期间中，无线装置100使用第一WIFI信道与电子装置220(BSS0)通信，以及此时无线装置100不与电子装置210以及210通信。
During a second period following the first period, the wireless device 100 uses the first Wi-Fi channel to communicate with the electronic device 220 (BSS 0), and at this time the wireless device 100 does not communicate with the electronic devices 210 and 230.
在紧着第二期间的第三期间中，无线装置100使用蓝牙与电子装置210通信，以及使用第二WIFI信道与电子装置230(BSS1)通信，其中所选择的蓝牙信道可能具有与第一期间不同的频率。
During a third period following the second period, the wireless device 100 uses the Bluetooth to communicate with the electronic device 210, and uses the second Wi-Fi channel to communicate with the electronic device 230 (BSS 1), where the selected Bluetooth channel may have different frequency with the first period.
然后，在接着第三期间的第四期间中，无线装置100使用第一WIFI信道来与电子装置220(BSS0)通信，等等。
Then, during a fourth period following the third period, the wireless device 100 uses the first Wi-Fi channel to communicate with the electronic device 220 (BSS 0)... and so on.
在图3示出的实施例中，为了具有更好的性能，一般来说，蓝牙与第一WIFI信道之间的频率差异小于蓝牙与第二WIFI信道之间的频率差异。
In the embodiment shown in FIG. 3, in order to have the better performance, on the average, a frequency difference between the Bluetooth and the first Wi-Fi channel is less than a frequency difference between the Bluetooth and the second Wi-Fi channel.
例如，第一WIFI信道可以是信道1(2437MHz)，第二WIFI信道可以是信道6(2412MHz)，以及蓝牙信道可以是2437MHz-2480MHz(跳频)。
For example, the first Wi-Fi channel may be channel 1 (2437 MHz), the second Wi-Fi channel may be channel 6 (2412 MHz), and the Bluetooth channel may be 2437 MHz-2480 MHz (hopping frequency).
在上述实施例中，因为仅一个WIFI信道与蓝牙信道同时使用，蓝牙将具有足够的信道用于AFH来改善蓝牙通信的性能。
In the above-mentioned embodiment, because the only one Wi-Fi channel is used with the Bluetooth at the same time, the Bluetooth will have enough channels for the AFH to improve the performance of the Bluetooth communications.
此外，因为即使使用了一个蓝牙以及两个WIFI信道，播送时间仅需要分开成两部分，通信效率将不会更糟。
In addition, because the air-time only needs to be separated to two parts even if one Bluetooth and two Wi-Fi channels are used, the communication efficiency will not be worsened.
此外，以上提到的蓝牙以及WIFI仅用于说明性的目的。
In addition, the Bluetooth and Wi-Fi mentioned above are for illustrative purposes only.
在本发明的其他实施例中，可以在无线装置100的混合模式中使用其他类型的无线网络技术。
In other embodiments of the present invention, other types of wireless network technologies may be used in the hybrid mode of the wireless device 100.
这一可选设计将落入本发明的范围内。
This alternative design shall fall within the scope of the present invention.

步骤404：使用TDD模式与该第一电子装置以及该第二电子装置通信。
Step 404: use TDD mode to communicate with the first electronic device and the second electronic device.
步骤406：使用FDD模式与该第一电子装置以及该第三电子装置通信。
Step 406: use FDD mode to communicate with the first electronic device and the third electronic device.
简单来说，在无线通信方法以及相关无线装置中，同时使用TDD模式以及FDD模式来与多个电子装置通信。
Briefly summarized, in the wireless communication method and associated wireless device, the TDD mode and the FDD mode are simultaneously used to communicate with a plurality of electronic devices.
藉由使用本发明的混合模式，蓝牙可以具有足够的信道用于AFH来改善蓝牙通信的性能，以及即使使用了一个蓝牙以及两个WIFI信道，TDD模式的播送时间仅需要被分成两部分。
By using the hybrid mode of the present invention, the Bluetooth may have enough channels for the AFH to improve the performance of the Bluetooth communications, and the air-time for the TDD mode only needs to be separated to two parts even if one Bluetooth and two Wi-Fi channels are used.
因此，在同时使用WIFI MCC以及蓝牙时，本发明的无线通信方法可以改善效率以及性能。
Hence, the wireless communication method of the present invention can improve the efficiency and performance while the Wi-Fi MCC and Bluetooth are used.

然后将构建平台118降低选定的层增量，使其位于构建表面130以下。
Build platform 118 is then lowered below build surface 130 by a selected layer increment.
层增量影响增材制造过程的速度以及所制造的部件或零件190的分辨率。
The layer increment affects the speed of the additive manufacturing process and the resolution of a components or parts 190 being manufactured.
作为示例，层增量可以为约10至100微米(0.0004至0.004英寸)。
As an example, the layer increment may be about 10 to 100 micrometers (0.0004 to 0.004 in.).
然后，添加粉末在被能量源120熔融之前被沉积在构建平台118上。
Additive powder is then deposited over the build platform 118 before being fused by energy source 120.
具体地说，供应致动器154可以升高供应平台152以推动粉末通过供应开口140，从而将其暴露在构建表面130上方。
Specifically, supply actuator 154 may raise supply platform 152 to push powder through supply opening 140, exposing it above build surface 130.
然后重涂覆机机构114通过重涂覆机致动器160可以在构建表面130上移动，以将升高的添加粉末142水平地铺展在构建平台118上(例如，以选定的层增量或厚度)。
Recoater mechanism 114 may then be moved across build surface 130 by recoater actuator 160 to spread the raised additive powder 142 horizontally over build platform 118 (e.g., at the selected layer increment or thickness).
以期望的厚度铺展在粉末床上的添加粉末142在本文中可以被称为构建层192。
The additive powder 142 that is spread over the powder bed at the desired thickness may be referred to herein as the build layer 192.
随着重涂覆机机构114从左到右经过时(如图1所示)，任何过量的添加粉末142都通过储存器开口144掉落到溢流储存器116中。
Any excess additive powder 142 drops through the reservoir opening 144 into the overflow reservoir 116 as recoater mechanism 114 passes from left to right (as shown in FIG. 1 ).
