Patent number: 9871577Abstract: A method for modifying a communication signal for transmission from a source to a destination includes identifying a target platform for communicating with a communication device and establishing a communication connection between the target platform and the communication device. The method includes identifying an available communication channel for communicating data between the target platform and the communication device, and receiving control inputs from one or more sensors. The method also includes determining a pseudo random noise spreading code based on the received control inputs, and modifying a communication signal by multiplying the communication signal with the pseudo random noise spreading code. Additionally, the method includes causing transmission of the modified communication signal from the communication device to the target platform through the available communication channel, the modified communication signal being transmitted below a thermal noise of the available communication channel.Type: GrantFiled: November 30, 2015Date of Patent: January 16, 2018Assignee: Google LLCInventors: Dedi David Haziza, Arnd Geis

Patent number: 9866336Abstract: A phased array antenna system includes an array of antennas having first antenna and second antennas disposed equidistantly from a third antenna. The first antenna is associated with a first gain and a first phase and the second antenna is associated with a second gain and a second phase. The first antenna receives a first reference signal corresponding to a calibration reference signal transmitted by the third antenna, and the second antenna receives a second reference signal corresponding to the calibration reference signal transmitted by the third antenna. The second receiver module is configured to adjust the second gain and the second phase associated with the second antenna to match the first gain and the first phase associated with the first antenna by comparing the first reference signal received by the first antenna with the second reference signal received by the second antenna.Type: GrantFiled: June 17, 2015Date of Patent: January 9, 2018Assignee: Google LLCInventors: Arnd Geis, Arnold R.

Patent number: 8841971Abstract: Systems and method that provide short circuit protection for a power amplifier are described. The system can include, for example, a sense network that receives an output current from the power amplifier that is to be protected. The sense network can include, for example, a first resistor and a second resistor in series. The sense amplifier has a first input and a second input in which the first input is coupled to a first end of the first resistor and in which second input is coupled to a second end of the first resistor. The sense amplifier amplifies a voltage across the first resistor of the sense network in which the voltage is based on the output current from the power amplifier. Based on the amplified voltage of the sense amplifier, the feedback network reduces the output current from the power amplifier to protect the power amplifier from damage due to a short circuit condition.Type: GrantFiled: December 17, 2012Date of Patent: September 23, 2014Assignee: Google Inc.Inventors: Arnd Geis, Benjamin Joseph Mossawir

Patent number: 8823457Abstract: Systems and methods for protecting circuits from short-circuit events are described. The system may include, for example, first circuitry that receives an output signal from a power amplifier to be protected from a short-circuit event. The first circuitry mirrors an output stage of the power amplifier and provides a mirrored current that mirrors an output stage current of the power amplifier. Second circuitry is operatively coupled to the first circuitry and to the power amplifier. The second circuitry includes, for example, a comparator circuit that compares the mirrored current to a reference current. A first transistor of the comparator circuit is in a mirror configuration with respect to a second transistor of the power amplifier. The second transistor sinks or sources current into the power amplifier to protect the power amplifier from the short-circuit event.Type: GrantFiled: December 17, 2012Date of Patent: September 2, 2014Assignee: Google Inc.Inventors: Benjamin Joseph Mossawir, Arnd Geis
