摘要： Infrared communications scheme for use in an embedded system. According to a preferred embodiment, the invention comprises the use of an infrared communications scheme, according to IrDA protocol, which is utilized to transmit and receive data optically between circuit cards housed within an enclosed, embedded system. Preferably, each respective circuit card is provided with an LED and photodiode to respectively transmit and receive data optically. As such, wire connections are eliminated and allows the systems and methods of the present invention to withstand a greater degree of vibration and shock than that of the prior-art systems and methods. Moreover, the systems and methods of the present invention provide increased reliability and provide greater electrical isolation between modules than prior-art systems and methods.

摘要： An unattended ground sensor for the monitoring of a remote area. The unattended ground sensor comprises a housing that supports a power source, a communications module, at least one sensor module and a mainframe module. Additionally, the unattended ground sensor includes a common electrical bus in electrical communication with the power source, the communications module, the at least one sensor module, and the mainframe module. The common electrical bus is operative to provide a communications pathway between the power source, the communications module, the at least one sensor, and the mainframe module. Accordingly, the mainframe module is operative to control the operation of the unattended ground sensor through the common electrical bus.

摘要： A method for tuning spread spread spectrum receivers to a frequency of a digital signal within a specified frequency band as the steps of coarse tuning the receiver while a preamble of the digital signal is being received, fine tuning the receiver while the preamble of the digital signal is being received, and demodulating the signal. Preferably, the step of coarse tuning the receiver comprises dividing the specified frequency band into a plurality of first sub-bands, and sequentially measuring a receive signal strength within each of the sub-bands until a receive signal strength is greater than a predetermined threshold. Preferably, the step of fine tuning the receiver comprises the dividing at least one first step-band which is found to have a receive signal strength greater than a predetermined threshold into a plurality of second sub-bands when a receive signal strength is greater than the predetermined threshold, sequentially measuring a receive signal strength within each sub-band so as to determine which second sub-band contains a signal having a receive signal strength above a predetermined threshold, and determining which second sub-band contained the signal with the greatest receive signal strength.
