Patent number: 9577484Abstract: A rotary electric machine includes a stator and a rotor. The rotor has at least one permanent magnet arranged in a d-axis magnetic path. 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.Type: GrantFiled: June 26, 2012Date of Patent: February 21, 2017Assignees: Nissan Motor Co., Ltd., Wisconsin Alumni Research FoundationInventors: Takashi Kato, Robert Lorenz, Natee Limsuwan

Patent number: 9532237Abstract: In a communications network with carrier aggregation (CA), embodiments enable the network to advertise to a supported wireless device not only whether or not aggregated component carriers allocated to the wireless are intra-band adjacent but further whether or not the allocated component carriers are collocated. Embodiments further enable the wireless to advertise its CA capabilities including the support of adjacent collocated CA and/or non-adjacent collocated CA. Embodiments thus provide systems/methods for the exploitation of special conditions provided by adjacent collocated component carriers to reduce processing complexity and power consumption for certain types of wireless device transmitter/receiver architectures and to support intra-band adjacent CA for other types of UE transmitter/receiver architectures.Type: GrantFiled: March 15, 2013Date of Patent: December 27, 2016Assignee: Broadcom CorporationInventors: Djordje Tujkovic, Louay Jalloul, Robert Lorenz

Patent number: 9247406Abstract: 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. Embodiments further provide highly robust SOS message transmission and reception schemes configured to enhance the successful detection and decoding of the SOS message by at least one base station of the cellular 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.Type: GrantFiled: March 15, 2013Date of Patent: January 26, 2016Assignee: Broadcom CorporationInventors: Robert Lorenz, Djordje Tujkovic, Erik Stauffer

Patent number: 9197175Abstract: 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.Type: GrantFiled: June 8, 2012Date of Patent: November 24, 2015Assignee: Broadcom CorporationInventors: Sriraman Dakshinamurthy, Robert Lorenz

Patent number: 9066368Abstract: 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.Type: GrantFiled: June 7, 2012Date of Patent: June 23, 2015Assignee: Broadcom CorporationInventors: Robert Lorenz, Sumant Ranganathan, Xinyu Yu, Sriraman Dakshinamurthy
