    • The present invention is directed to a frequency hopping spread spectrum transceiver. The transceiver includes a microcontroller; a transmitter having a voltage controlled oscillator, a direct digital synthesizer, and a power amplifier; and a receiver having an amplifier, a mixer, an IF amplifier, a demodulator, and a data slicer. When transmitting, the transmitter sends a preamble that allows the receiving device to detect the signal and lock to it to receive the data. When receiving, the receiver first scans all channels and sorts them based on a Received Signal Strength Indicator (RSSI) and then attempts to lock to the channel with the strongest RSSI value by first sampling the received signal to verify the preamble, then synchronizing to the bit edges of the received signal, then detecting the start of a Start Frame Delimiter (SFD), decoding bits to verify a valid SFD and then sampling data bits to receive the data.
    • 本发明涉及一种跳频扩频收发信机。 收发器包括微控制器; 具有压控振荡器的发射机,直接数字合成器和功率放大器; 以及具有放大器,混频器,IF放大器,解调器和数据限幅器的接收器。 发射时,发射机发送一个允许接收设备检测信号并锁定信号以接收数据的前同步码。 接收机首先对所有信道进行扫描,并根据接收信号强度指示符(RSSI)对其进行分类,然后通过首先对接收到的信号进行采样来验证前导码,然后尝试锁定具有最强RSSI值的信道,然后同步到 接收信号的位边沿,然后检测起始帧定界符(SFD)的开始,解码位以验证有效的SFD,然后采样数据位以接收数据。

    • An electric meter comprises an electronics housing and a meter base. The electronics housing defines a front panel and includes a first plurality of option board guides. A main meter board is disposed substantially parallel to the front panel. The meter base defines a rear panel of the electric meter. The meter base includes a plurality of housing guides for receiving the electronics housing and a second plurality of option board guides disposed substantially perpendicularly to the rear panel. The second plurality of option board guides are adapted to receive an option board and to position the option board substantially perpendicularly to the main meter board of the electronics housing during assembly of the electronics housing to the meter base. The housing guides in combination with the first and second pluralities of option board guides enable blind assembly of the electronics housing to the meter base.

    • The present invention is directed to a frequency hopping spread spectrum transceiver. The transceiver includes a microcontroller; a transmitter having a voltage controlled oscillator, a direct digital synthesizer, and a power amplifier; and a receiver having an amplifier, a mixer, an IF amplifier, a demodulator, and a data slicer. When transmitting, the transmitter communicates a preamble over a predetermined number of preamble channels, and thereafter communicate groups of data bytes that each comprise a subset of the data message over a predetermined sequence of data channels. When receiving, the receiver investigates the predetermined number of preamble channels to search for the preamble, each of the predetermined number of preamble channels being associated with a predetermined number of data channels in each sequence of data channels. A number of bytes that comprises each group of data bytes is determined in accordance with a number of channels in the sequence of data channels and the predetermined number of times each byte of the data message is to be transmitted.

    • A method, wireless mesh network and processor-readable storage medium for providing interoperability between devices that are capable of communicating at different data rates are disclosed herein. A start-of-frame delimiter token value in a synchronization header is used to indicate a data rate at which a device is capable of communicating. In certain embodiments, samples are collected around a bit transition and are used to adjust a bit timing of a receiving device to match a bit timing of a transmitting device using a coarse adjustment process and, in some embodiments, a fine adjustment process. In this way, compatibility can be maintained between new devices that can communicate at a relatively fast data rate and legacy devices that communicate at a lower data rate.
