Abstract: A mobile computing device is authenticated to a user using an NFC tag embedded within or attached to an object that is commonly carried or worn by the user. The NFC tag may be initially associated when an NFC reader of the device senses the NFC tag and wirelessly retrieves a tag identifier from the tag. The tag identifier is stored for subsequent retrieval. The authentication process begins by positioning the device proximate the object such that the NFC reader of the device retrieves the tag identifier from the NFC tag. In the event that the retrieved tag identifier matches the stored tag identifier, the mobile computing device is unlocked and the user may access the mobile computing device. If the retrieved tag identifier does not match the stored tag identifier, the user is not authenticated and the mobile computing device remains locked.

Abstract: A switching power supply device that can reduce power supply noise includes a switching power supply device main body that switches a semiconductor switching element at a power supply frequency fs, and supplies power to an electronic instrument such as an AM radio receiver. The switching power supply device detects an AM radio reception frequency fc and a power supply harmonic component that interferes with the AM radio reception frequency fc. Further, the switching power supply device determines, in a sideband of the AM radio reception frequency fc on a side that does not include the power supply harmonic component, a jitter width ?f for the power supply frequency fs, avoiding a bandwidth BW of the AM radio reception frequency fc, controlling the jitter of the power supply frequency fs in the jitter width ?f, and switching the semiconductor switching element at a frequency of [fs±?f/2].

Abstract: Technologies are described for reliably constraining a maximum transmission power of a mobile communication device such as a cellular phone so that RF radiation associated with that transmission and incident to a head of the device's user can be held at or below predetermined “safe” levels. Upon determining an operational or communication mode of the mobile communication device where it is likely to be held against or very near the user's head, its maximum transmit power may be reduced until the near-head operation is completed. The reduction may be to a fixed maximum level or may be adjusted to allow for a maximum amount of radiated energy over a period of time. The reduction may also take into account adjustment factors such as frequency band, modulation, antenna gain, and similar factors.

A second interface can be used in card mode and in reader mode and is configured to be connected to the antenna and to the first interface via the impedance matching external circuit. An internal module includes a first detection circuit configured to deliver a first detection signal that represents the phase antenna matching quality when the impedance matching external circuit and the antenna are indeed connected between the first interface and the second interface. The internal module is further configured to deliver a check signal from at least the first detection signal.

Abstract: To maintain linear operation of a signal processing circuit, such as a low noise amplifier, a peak detector detects a peak of a signal associated with the signal processing circuit and compares the detected peak signal with a threshold. When the detected peak signal is greater than the threshold, a fixed current source biases the signal processing circuit to place the signal processing circuit in a different mode of operation. The signal processing circuit may thereby process a larger input signal while operating in an acceptable linear region.

Abstract: Using a Bluetooth communication channel for point of sale processing simulates a near field communication connection. A contactless device and the point of sale reader establish an unsecure communication channel. The user taps the contactless device with a point of sale terminal reader. The contactless device creates receive signal strength indicator (“RSSI”) value spikes. The terminal reader measures the RSSI values and transmits them to the contactless device, which determines if the RSSI value reaches or exceeds a threshold configured for the contactless device. If the threshold is reached, the terminal reader and the contactless device establish a secure communication connection. The devices communicate via the secure communication connection, and the connection is terminated when a request to terminate is received.

Abstract: A near field RF communicator has an inductive coupler to enable inductive coupling with a magnetic field of an RF signal; a rectifier to rectify an AC voltage derived from an RF signal inductively coupled to the inductive coupler; and a regulator to regulate a voltage derived from an RF signal inductively coupled to the inductive coupler, the regulator having a voltage-controlled impedance and a regulator controller to provide a control voltage for the voltage controlled impedance and to vary the control voltage in dependence upon a current flowing through the voltage controlled impedance. To prevent the voltage regulator from drawing excess current and energy from an RF field in which the communicator is present the voltage regulator is controlled to provide a chosen impedance characteristic.

Abstract: A method detects narrow band interference in wireless networks by first thresholding each block of samples to produce thresholded samples. The samples are normalized frequency magnitudes obtained from a spectrum of a wireless signal in a channel. Each block of the thresholded samples is summed to produce a thresholded value for each block. Then, thresholded values are autocorrelated to determine whether a bandwidth of the wireless signal is consistent with narrow band interference.
