    • A machine comprises a processor and at least one other component. The processor determines if the other component needs service, and sends an electronic message addressed to a remote communication device accessible by a user of the machine. The service includes at least one of: repair, replacement and replenishment of the component, and the electronic message indicates the need for the service and includes information to facilitate ordering at least one of: the repair, replacement and replenishment of the other component. The electronic message may include at least one of: an e-mail message, a text message, an instant message, and an SMS message, and may be forwarded to a supplier to place an order for the repair, replacement and replenishment of the other component.
    • 机器包括处理器和至少一个其它部件。 处理器确定其他组件是否需要服务,并且发送寻址到由机器的用户可访问的远程通信设备的电子消息。 该服务包括以下至少一个:维修,更换和补充组件,电子消息表示需要该服务,并且包括信息以便于订购至少一个:维修,更换和补充其他组件。 电子消息可以包括以下各项中的至少一个:电子邮件消息,文本消息,即时消息和SMS消息,并且可以转发给供应商以下订单来修复,替换和补充另一个 零件。

    • A transmitter shifts a baseband data signal having a bandwidth of 2ωM using a tone signal having a frequency ωM, which centers a sideband of the data signal at zero frequency. The transmitter then filters the shifted signal to filter out the non-centered sideband, and then adds the tone signal to form a composite signal. The transmitter upconverts the composite signal during a first operational mode using a RF signal having a frequency ωC equal to a center frequency of a channel. In a second operational mode, the transmitter upconverts a DC level using the same RF signal. The upconverted DC level can be used as a continuous wave carrier signal having a frequency ωC. The transmitter has a single RF oscillator to output both a SSB signal centered at frequency ωC during the first mode and a carrier signal of frequency ωC during the second mode.
    • 发射机使用具有频率ωM M M的音调信号来移动具有2omega M带宽的基带数据信号,该频率ωM是使数据信号的边带以零频率居中。 然后,发射机对移位的信号进行滤波,以滤除非中心边带,然后将音调信号相加以形成复合信号。 发射机在第一操作模式期间使用具有等于信道的中心频率的频率ω-C的RF信号来上变频合成信号。 在第二种操作模式中,发射器使用相同的RF信号上变频DC电平。 上转换的DC电平可以用作具有频率ωC的连续波载波信号。 发射机具有单个RF振荡器,以在第一模式期间输出以频率ω-C'为中心的SSB信号,并且在第二模式期间输出频率ωC'C的载波信号。
