    Abstract: A technique for reducing interference on conducted RF links involves a determination of active wireless channels in an electronic device. For example, the device can determine whether there are any active cellular, WiFi, and/or Bluetooth channels. If so, any active channels can be removed from a list of possible channels that can be used for generating the RF signals for the conducted RF link. If any idle channels remain available, one or more may be selected for use for the conducted RF link. Those idle channels having a higher offset from any active channels may be given a greater weight in the selection since they should be less likely to be subject to interference. If not, one of the least crowded active channels may be selected for use for the conducted RF link.

    Abstract translation: 用于减少对传导RF链路的干扰的技术涉及确定电子设备中的主动无线信道。 例如，设备可以确定是否存在活动的蜂窝，WiFi和/或蓝牙信道。 如果是这样，可以从可用于生成用于传导RF链路的RF信号的可能信道的列表中移除任何活动信道。 如果任何空闲信道保持可用，则可以选择一个或多个用于所传送的RF链路。 那些具有比任何活动通道偏移较大的空闲信道可能在选择中给予较大的权重，因为它们应该不太可能受到干扰。 如果不是，可以选择最不拥挤的活动频道中的一个用于传导的RF链路。

    Abstract: Systems and method for improving design and/or operation of a radio frequency system are provided. One embodiment provides a radio frequency system, which includes a first look-up table that describes a static reference value, association between a maximum output power and a first specification level, and association between a first back off value and a second specification level, in which the first back off value is defined in relation to the static reference value and used to determine a first reduced output power; and a second look-up table that describes association between the maximum output power and a first set of operational parameters and association between the first reduced output power and a second set of operational parameters. The radio frequency system wirelessly transmits the analog electrical signal in compliance with an instructed specification level instruction by determining a desired output power based on the instructed specification level using the first look-up table and implementing operational parameters determined based on the desired output power using the second look-up table.

    Abstract: A method for controlling transmission power in accordance with a total transmission power limit in a multi-radio wireless communication device including a master radio and a slave radio is provided. The method can include the wireless communication device determining, at the master radio, a transmission power of the master radio. The method can further include the wireless communication device providing information indicative of the transmission power of the master radio from the master radio to the slave radio. The method can additionally include determining, at the slave radio, an allowable transmission power for the slave radio. A sum of the allowable transmission power and the transmission power of the master radio may not exceed the total transmission power limit.

The wireless communications circuitry may include radio-frequency transceiver circuitry and antenna structures. An electronic device may include a display mounted within a housing. A peripheral conductive member may run around the edges of the display and housing. Dielectric-filled gaps may divide the peripheral conductive member into individual segments. A ground plane may be formed within the housing from conductive housing structures, printed circuit boards, and other conductive elements. The ground plane and the segments of the peripheral conductive member may form antennas in upper and lower portions of the housing. The radio-frequency transceiver circuitry may implement receiver diversity using both the upper and lower antennas. The lower antenna may be used in transmitting signals.

    Abstract: A wireless power transmission system may include a wireless power transmitting device such as a tablet computer and a wireless power receiving device such as a computer stylus. A wireless power transmitting capacitor electrode may be formed in the tablet computer. A wireless power receiving capacitor electrode may be formed in the computer stylus. The transmitting capacitor electrode may be driven by a drive signal having a frequency of 900 MHz or greater to produce wireless power. The wireless power may be transmitted from the transmitting capacitor electrode to the receiving capacitor electrode on the stylus via near field capacitive coupling. The transmitting and receiving capacitor electrodes may each include conductive traces on dielectric substrates. The conductive traces may follow meandering paths to maximize the possible capacitive coupling efficiency between the capacitor electrodes and thus the end-to-end charging efficiency of the wireless power transmission system.
