摘要： A wireless network permits wireless devices to determine their own location and receive location-based services. The network includes a communication server coupled to a plurality of access points and at least one mobile wireless device that wirelessly communicates through the access points. Each wireless device includes a location table through which the wireless device can determine its physical location. The location table includes the physical location of the various access points indexed by their network addresses. When the wireless device communicates with an access point, the access point provides the wireless device its address. The wireless device uses the address of the access point as an index into the location table to determine its own location based on the location of the access point. Once the wireless device has determined its own physical location, it requests location-based services from or through the communication server.

摘要： A portable personal computer, such as a notebook computer, is provided with an infrared (IR) port which is accessible to IR light signals sent toward the frontal face or aspect of the computer, where the data entry mechanism, such as a keyboard or touchpad, is located. The computer system may also include a conventional, rear mounted infrared light entry port, so that infrared communications may be made to the computer from several directions, such as both the front and rear of the computer. This overcomes the need for special cabling and a separate electronics board for extra IR interface electronics in the portable computer housing, where space is typically at a premium.
摘要翻译：诸如笔记本电脑的便携式个人计算机设置有红外线（IR）端口，该红外线（IR）端口可接近朝向计算机的正面或方面发送的红外光信号，其中数据输入机构，例如键盘或触摸板，位于。计算机系统还可以包括常规的后置红外光进入端口，使得可以从诸如计算机的前部和后部的多个方向向计算机进行红外通信。这克服了在便携式计算机外壳中需要特殊布线和单独的电子板用于额外的IR接口电子设备，其中空间通常是非常重要的。
