摘要： A radar system (25) and method for determining the range and, optionally, the azimuth of a target, while maintaining a high transmitting duty factor is provided. A waveform generator (30) is connected to an antenna aperture by a transmit-receive switch (32,34), and the waveform is transmitted for more than half of the period of time of the sum of the transmission period and the receiving period. For a frequency-modulated continuous-wave waveform (FMCW), the receiver may be turned on for short intervals at a rate which is at least the Nyquist rate for the signal received from at target. A monopulse or frequency-scanned antenna may be used to determine azimuth as well as range.

摘要： A cable-free programmable radio is described. In one exemplary implementation, a radio includes an infrared port configured to receive programmable information from a host device via an infrared signal. The radio also includes a control system having a selectable programmable mode to enable the radio to download the programmable information from the host device and configure the radio function in accordance with the programmable information. A radio may be configured/reconfigured (such as when "cloning" the radio) by connecting the radio to a host device through the infrared port, wirelessly.

摘要： A proxy is utilized to limit the RF bandwidth needed for foreign IP registration. An existing RF login procedure causes the proxy to initiate and complete the foreign IP registration procedure with the foreign agent at the RF site where the mobile node is located. The proxy then acts as a locally connected (i.e., direct ethernet connected) device for each IP address for which it is proxying, and thus there is no need to use RF to register a mobile with the active foreign agent. This allows the use of off-the-shelf home and foreign agents to complete the mobile IP architecture, and reduces the RF bandwidth used, since the RF portion of the registration process (the registration between the active foreign agent and the mobile) is reduced.
摘要翻译：利用代理来限制外部IP注册所需的RF带宽。现有的RF登录过程使得代理在移动节点所在的RF站点上与外部代理发起和完成外部IP注册过程。代理随后作为其正在代理的每个IP地址的本地连接（即，直接以太网连接）设备，因此不需要使用RF来向活动外部代理注册移动设备。由于注册过程的RF部分（活动外部代理和移动设备之间的注册）被减少，因此允许使用现成的本地和外部代理来完成移动IP架构并降低使用的RF带宽。

摘要： A phase locked loop includes a buffer that synchronizes the transmission of the new count value to the completion of the previous count to avoid errors caused by dithering. The buffer is connected to a count input of the counter and transmits the new count upon receipt of the carryout signal from the counter. Alternatively, the transmission of the new value of N from the buffer is delayed after receipt by the buffer of a carryout signal from the counter. In another embodiment, a delayed version of the carryout signal is used to trigger the buffer to transmit the new count value to the counter. In another feature, a buffer synchronizes phase data to a reference signal before inputting it to a digital modulator of the phase locked loop.
