The rotor includes a magnetic gap part located between the permanent magnet arranged in the d-axis magnetic path of one pole and an adjacent magnet with a different polarity, such that a d-axis magnetic flux forms a d-axis bypass passing through an area other than the permanent magnet. The d-axis bypass provides a magnetic resistance in a d-axis direction that is set below a magnetic resistance in a q-axis direction that is orthogonal to the d-axis resistance.

Abstract: Embodiments provide systems and methods to dynamically control a radio frequency (RF) transmitter based on monitored error vector magnitude (EVM) performance. Embodiments are enabled by a feedback path that allows estimating the EVM at the output of the transmitter and controlling the transmitter, including the power amplifier (PA), accordingly. As such, the transmitter (and the PA) can be operated as close as possible to the ideal operating point that meets, based on actual conditions, a specified EVM performance and desired output power. By doing so, the overall power consumption of the transmitter is reduced.

Abstract: Various embodiments of the present invention recognize at least two zones of operation for a communication device. In a first zone, which is sufficiently spaced away from a human head or body that SAR limits will be met, transmit power delivered to an antenna of a communication device may be maximized within any other constraints under which the communication device operates. In a second zone, which is not sufficiently spaced away from a human head or body, transmit power is redistributed such that SAR limitations are met without affecting the transmit power control loop of the communication device. For example, a second antenna physically disposed at a different location within the communication device may be used either instead of, or in addition to, the first transmit antenna in order that the SAR limits are met.

In another embodiment, the antenna tuner is controlled based on measurement of the voltage reflection coefficient S11.

Abstract: Embodiments provide methods and systems for transmitting an emergency (SOS) message from a user (UE) to a cellular network in a highly robust and energy efficient manner. Specifically, embodiments enable the SOS message to be sent in a synchronous manner despite the asynchronous nature of the network, which significantly enhances the probability of successful reception of the SOS message by at least one base station (eNodeB) of the network.

In addition, embodiments enable the synchronous transmission of the SOS message to the network without requiring network attachment by the UE. This makes embodiments highly suited for emergency situations in which network coverage is affected and can enable significant and precious power savings at the UE.

Abstract: Embodiments provide systems and methods for aligning the supply voltage signal applied to a power amplifier (PA) with the radio frequency (RF) output signal of the PA in a wireless device. The RF output signal is generated by applying a transmit signal to a transmit path of the wireless device. The supply voltage is generated by applying an envelope tracking (ET) signal, based on the transmit signal, to an envelope tracking (ET) path of the wireless device. Embodiments operate by estimating the delays of the ET path and the transmit path, and then controlling a relative delay between the transmit signal and the ET signal accordingly. In an embodiment, estimation of the delays of the ET path and the transmit path is done by correlating respective signals of each path.

Abstract: Embodiments provide systems and methods for producing an envelope tracking (ET) PA supply voltage with minimum headroom relative to the desired RF output signal of the PA. In an embodiment, the PA supply voltage is generated by applying an ET signal to an ET path of the wireless device, and by further applying pre-emphasis to the ET signal to compensate for a frequency response of the ET path. Embodiments operate by estimating the frequency response of the ET path and determining the pre-emphasis based on the estimate of the frequency response of the ET path. In embodiments, the pre-emphasis is applied using a pre-emphasis filter, which may be within or outside of the ET path. Further, the pre-emphasis may be applied to the ET signal in digital or analog form.
