A wireless communication device or a split band diversity antenna arrangement (or) has a first multi-band antenna (or) located at a bottom portion () of the wireless communication device and selectively coupled to a diversity receiver (), a second multi-band antenna (or) located at a top portion () of the wireless communication device and selectively coupled to a dual band transceiver (), a band splitter () splitting an input from the first antenna into a first output and a second output where the first output serves as an input to the diversity receiver, and a band combiner () that combines the second output of the band splitter with a signal from the second antenna to provide an input signal to the dual band transceiver.

Split band diversity antenna arrangement

A Personal Area Network (PAN) () including multiple communication devices () is provided. The communication devices are capable of communicating with each other and a connection point. The communication devices derive energy from multiple fuel cells (). The PAN is capable of distributing fuel to the multiple fuel cells from a common fuel container (), if the communication devices are attached to the connection point.

System and method for distributing fuel to multiple fuel cells

Methods in intermediate frequency and direct conversion receivers for reducing pre-selection filter leakage and harmonic coupling to a programmable voltage controlled oscillator by mixing a receive signal at a mixer having a mixer injection frequency outside a pre-selection filter passband. In some applications, the mixer injection frequency is conditionally moved outside the pre-selection filter passband. In other applications, signal gain is increased to compensate for any loss resulting from shifting the mixer injection frequency outside the pre-selection passband.
