Abstract: A vehicle network node module includes device buffers, a network buffer, a switch circuit, and a processing module. The device buffers temporarily store outgoing device packets from, and temporarily store incoming device packets for, vehicle devices in accordance with a locally managed prioritization scheme. The network buffer receives incoming network packets from, and outputs the outgoing network packets to, a vehicle network fabric in accordance with a global vehicle network protocol. The network buffer also temporarily stores the incoming network packets and the outgoing network packets in accordance with the locally managed prioritization scheme. The switching circuit selectively couples the network buffer to individual ones of the device buffers in accordance with the locally managed prioritization scheme. The processing module interprets the outgoing device packets and the incoming network packets to determine types of packets and determines the locally managed prioritization scheme based on the types of packets.

Abstract: Systems and methods are provided that allow a touch sensor, such as a mutual capacitive touch panel, to switch from an operative transmit (TX) frequency at which the mutual capacitive touch panel is driven to an alternative TX frequency. When switching to an alternative TX frequency, an alternative baseline capacitance value corresponding to the alternative TX frequency may be utilized to determine whether a touch event has occurred on the mutual capacitive touch panel. Frame scans can be repeatedly performed at the operative TX frequency and the alternative TX frequency in rapid succession, and an average difference of the frame scans can be calculated and utilized to generate the alternative baseline capacitance value which may be insensitive to sudden ambient changes and moving touch events affecting the mutual touch capacitive panel.

Abstract: A communication device includes a first and second near-field wireless (NFW) module operating with a first and second protocol, respectively. A module and method to improve the operational efficiency of the first and second NFW modules are disclosed. Due to close proximity between the first and second NFW modules in the communication device, an undesirable parasitic inductive coupling can occur that can degrade the operational performance of the modules. The first NFW module can be configured to control inductive coupling of the second NFW module when an electromagnetic (EM) field operating with the first protocol is detected. Additionally, the second NFW module can be configured to control inductive coupling of the first NFW module when an EM field operating with the second protocol is detected. Controlling the inductive coupling of each module can be performed by means of detuning an inductive coupling element of each module.

Abstract: An apparatus and method are disclosed to control the mutual coupling between wireless power transfer (WPT) enabled devices. Wireless power transfer is best achieved when both the transmitting and receiving device are tuned to substantially the same frequency. Because WPT-enabled devices are coupled to one another during WPT, tuning one WPT-enabled device can cause both devices to converge to a resonance together. Furthermore, a WPT enabled receiving device can be intentionally detuned to avoid coupling excessive power from a WPT-enabled transmitter device. These concepts can be extended to WPT-enabled device pairs that each has WPT transmission and reception qualities. When multiple WPT-enabled devices interact, tuning information can be stored in one or both of the devices to make the configuration procedure for subsequent WPT interactions more efficient. Various systems are presented to control the mutual coupling between WPT-enabled devices to improve the WPT.

Abstract translation: 公开了一种用于控制无线功率传输（WPT）使能设备之间的相互耦合的装置和方法。 当发送和接收设备都被调谐到基本上相同的频率时，无线功率传输是最好的。 由于WPT使能设备在WPT期间彼此耦合，所以调谐一个支持WPT的设备可能会导致两个设备一起收敛到一个共振。 此外，启用WPT的接收设备可能被故意失谐，以避免从支持WPT的发射机设备耦合过多的功率。 这些概念可以扩展到具有WPT传输和接收质量的WPT设备对。 当多个支持WPT的设备进行交互时，调优信息可以存储在一个或两个设备中，以使后续WPT交互的配置过程更有效率。 提出了各种系统来控制支持WPT的设备之间的相互耦合，以改善WPT。

Abstract: A wireless device includes processing circuitry, a receiver section, a transmitter section, and an antenna. The processing circuitry determines a set of information signals of a RF Multiple Frequency Bands Multiple Standards (MFBMS) signal. The receiver section down-converts a portion of the RF MFBMS signal by one or more respective shift frequencies to produce a corresponding baseband/low Intermediate Frequency (BB/IF) information signal from which the processing circuitry extracts data. The transmitter section converts a respective BB/IF information signal received from the processing circuitry by a respective shift frequency to produce a corresponding RF information signal and a combiner that combines the RF information signals to form a RF MFBMS signal. The receiver section and the transmitter section include ADCs and/or DACs, respectively, that are adjustable based upon characteristics of the RF MFBMS signal, the BB/IF MFBMS signal, and/or based upon signals carried therein, e.g., modulation type, SNR requirements, etc.
