  • Patent number: 9374698
    Abstract: An individual uses a communication device to provide information identifying the type of emergency that the individual is experiencing. In response to receiving an emergency alert, an inquiry as to whether the received emergency alert relates to a medical emergency or to a non-medical emergency is generated and provided to the user. Upon receiving a response indicating that the emergency alert relates to a medical emergency, a medical history of the individual is automatically retrieved and a geographical location of the user is determined. A medical emergency service that is suitable for determining a type of medical assistance required by the individual is automatically identified based on the received confirmation and the retrieved medical history. A bi-directional communication with a communication device of the identified medical emergency service is established to upload to a data storage element of the communication device the medical history and geographical location of the individual.

  • Patent number: 8233852
    Abstract: An apparatus may include a non-linear module, a control module, and a calibration module. The non-linear module produces an output signal from an input signal. The control module selects, upon an occurrence of a calibration condition, a calibration operation from two or more calibration operations. Each of the two or more calibration operations may generate one or more correction values for the non-linear module. Further, each of the calibration operations produces the input signal from a pre-input signal. This selected calibration operation is performed by the calibration module. The two or more calibration operations include a first calibration operation and a second calibration operation. The first calibration operation produces the input signal from the pre-input signal according to a predictive technique. The second calibration operation produces the input signal from the pre-input signal according to a non-predictive technique.

  • Patent number: 7983359
    Abstract: Various techniques involving polar modulation are disclosed. For instance, an apparatus may include a storage medium and a calibration module. The storage medium stores multiple adjustment settings. Each of these adjustment settings corresponds to an operating condition. The calibration module selects one of the stored adjustment settings that corresponds to a current operating condition. With the selected adjustment setting, the calibration module reduces a polar modulation timing misalignment. The current operating condition may include one or more operational parameter values. Examples of such parameter values include output power level, signal frequency, and/or temperature.

  • Patent number: 7653362
    Abstract: An apparatus and method for characterizing an amplifier transmitting a band limited signal using a sample of the input signal to the amplifier and a sample of the output signal from the amplifier, where the output signal is sub-sampled. The sub-sampling frequency is chosen such that images of the band limited signal do not overlap. The input signal and the output signal in a polar format are processed to determine characteristics such AM/AM and AM/PM conversion nonlinearities.

  • Publication number: 20090253398
    Abstract: Techniques are disclosed for producing RF signals from baseband signals. For instance, an apparatus may include an intermediate frequency (IF) signal generation module, and an upconversion module. The IF signal generation module produces an analog IF signal from a digital baseband signal. In turn, the upconversion module generates a radio frequency (RF) output signal from the analog IF signal. The upconversion module may include a translational phase locked loop (PLL) to receive the analog IF signal and to produce the RF output signal. The RF output signal may be for transmission in a wireless communications network, such as a cellular network.
