    摘要： A low-power radio-frequency (RF) receiver is characterized by a decreased current consumption such that the RF received may be used in control devices, such as battery powered motorized window treatments and two-wire dimmer switches. The RF receiver uses an RF sub-sampling technique to check for the RF signals and then put the RF receiver to sleep for a sleep time that is longer than a packet length of a transmitted packet to thus conserve battery power and lengthen the lifetime of the batteries. The RF receiver compares detected RF energy to a detect threshold that may be increased to decrease the sensitivity of the RF receiver and increase the lifetime of the batteries. After detecting that an RF signal is being transmitted, the RF receiver is put to sleep for a snooze time period that is longer than the sleep time and just slightly shorter that the time between two consecutive transmitted packets to further conserve battery power.

    摘要翻译： 低功率射频（RF）接收器的特征在于降低的电流消耗，使得所接收的RF可以用于控制装置，例如电池驱动的电动窗帘和双线调光器开关。 RF接收器使用RF子采样技术来检查RF信号，然后使RF接收器睡眠达睡眠时间，该睡眠时间长于发送的分组的分组长度，从而节省电池电量并延长 电池。 RF接收器将检测到的RF能量与检测阈值进行比较，检测阈值可以增加以降低RF接收器的灵敏度并延长电池的寿命。 在检测到RF信号正在被发送之后，RF接收器被置于休眠时间段，该休眠时间段比休眠时间长，并且稍微短于两个连续发送的数据包之间的时间以进一步节省电池电量。
