摘要： Systems and methods for reducing detection and interference of signals communicated from a communication device. The methods comprise: coupling an RF-to-FSO converter to a port of the communication device; providing a first radio frequency signal from the communication device to the RF-to-FSO converter via the port; using the first radio frequency signal by the RF-to-FSO converter to modulate an optical signal; and emitting the modulated optical signal from the RF-to-FSO converter through free space.

摘要： Systems (100) and methods (800) for communicating information. The methods comprise: storing message sets in Communication Devices ("CDs") so as to be respectively associated with speaker information; performing operations, by a first CD, to capture an audio message spoken by an individual and to convert the audio message into a message audio file; comparing the message audio file to each reference audio file in the message sets to determine whether one of the reference audio files matches the message audio file by a certain amount; converting the audio message into a text message when a determination is made that a reference audio file does match the message audio file by a certain amount; generating a secure text message by appending the speaker information that is associated with the matching reference audio file to the text message, or by appending other information to the text message; transmitting the secure text message.

摘要： Systems ( 100 ) and methods ( 1000 ) for operating a shoulder Speaker Microphone ("SM") device coupled to a radio. The methods comprising: using a speaker and a microphone of the shoulder SM device to facilitate auditory communications to and from a user of the radio; activating a thermal imaging device integrated with the shoulder SM device when the shoulder SM device resides at a location of an incident event; capturing thermal images by the thermal imaging device of the shoulder SM device; and performing operations by the shoulder SM device to cause the thermal images to be streamed over a network.

摘要： Limiting frequency overshoot in a timing recovery loop involves using a proportional-integral (PI) control system to discipline a frequency of an output signal of a voltage controlled oscillator (VCO) in accordance with a time reference signal. A control signal output of the PI control system is monitored to detect conditions which will prospectively cause an excess deviation of the VCO frequency. In response to detecting such a condition, an output of an integral error term generator of the PI control system is locked or held constant. This will have the effect of preventing the excess frequency deviation of the VCO.

摘要： Systems and methods for operating a communication device. The methods comprise: concealing the communication device and/or at least one cable in a ballistic wearable item (e.g., a ballistic vest) such that the communication device resides in a storage slot for a trauma plate, where the communication device comprises a frame having a cross-sectional profile that matches a cross-sectional profile of the trauma plate by a given amount (e.g., 75-100%); and performing communication operations by a radio module integrated with the frame of the communication device.

摘要： An RF device may include RF circuitry having a PIN diode configured to switch an RF signal, and a biasing circuit. The biasing circuit may include a controllable power supply having a control input and an current output coupled to the PIN diode to selectively bias the PIN diode into an ON state, and a feedback circuit coupled between the current output and the control input of the controllable power supply to set a current delivered to the PIN diode in the ON state.

摘要： Systems and methods for operating a communication device. The methods comprise: monitoring, by the processor, states of snap-dome based switches of a keypad provided with the communication device; activating, by the processor, a first timer when the snap-dome based switches are simultaneously activated; detecting, by the processor, when maintenance of the communication device is needed based on a value of the first timer; and causing, by the processor, performance of communication device maintenance based on the detecting, for immersion time and immersion depth fatique.
