    Abstract: A wireless communications system and channel-switching method are disclosed herein. A source device and multiple sink devices independently maintain respective counters which track data packet errors. Each device independently switches channels only after its counter reaches a channel-switching threshold. The new channel switched-to is either determined by an indexed ordering of the available channels or by reference to a global clock maintained by each of the devices. Accordingly, all devices quickly arrive at a common channel. The system switches channels only when necessary and resolves quickly to a mutually acceptable channel. Therefore, unnecessary channel switching is minimized and data throughput is optimized.

    Abstract translation: 本文公开了无线通信系统和信道切换方法。 源设备和多个宿设备独立地维护跟踪数据分组错误的相应计数器。 每个设备只有在其计数器达到通道切换阈值后才独立地切换通道。 新的信道切换是由可用信道的索引排序或参考由每个设备维护的全局时钟确定的。 因此,所有设备快速到达公共通道。 系统仅在必要时切换通道,并快速解决相互可接受的通道。 因此,不必要的信道切换被最小化并且数据吞吐量被优化。

    Abstract: An improved receiver architecture and method for a wireless transceiver (e.g. for a headphone) is provided whereby the receiver, advantageously, enables the use of only one synthesizer circuit for both the RF-to-IF and IF-to-base band conversion processes which, in turn, provides for lower power consumption. The receiver includes an injection locked local receiver oscillator (Rx LO) which is used for the first mixing stage (i.e. the RF-to-IF conversion). The Rx LO 105 is thereby able to use a high-level harmonic of a relatively low reference frequency signal produced by that synthesizer (e.g. a fractional-N phase locked loop circuit (PLL)). The receiver further includes a tunable Q-enhanced IF filter 110 and complex sub-sampling and mixing down-conversion circuitry for the second conversion stage (i.e. IF-to-baseband conversion). The sampling frequency used for the second conversion stage is a harmonic of the reference frequency derived from the synthesizer (PLL). For example, transceiver channels may be designed on the basis that the RF frequency F R1 is assigned a value of (n±¼)•f s , where the frequency f PLL of the PLL may be chosen to be twice the sub-sampling frequency f s and the frequency f Rx LO of the Rx LO may be nine times the frequency f PLL .

    Abstract: Electronic apparatus and method are provided for management of communications between channel master (e.g. audio player), responding device (e.g. remote control/headphones) and, optionally, passive devices (e.g. headphones) wirelessly connected in a wireless audio network. The channel master transmits, and the responding device receives, audio signals and network management information. Profile negotiation means communicates application profiles for the devices, establishing at least one application profile which is common to them and designating a selected, common application profile for use in associating the devices. Channel selection means selects a channel for the communications using an ordered selection of channels (PCS) obtained from scanning the channels for idle channels and ordering the scanned channels according to priority based on channel quality. Normalized control and status interfaces establish interoperability between devices which use different data streams to communicate in the network.

    Abstract: Systems and methods related to digital frequency locked looping to synchronize frequencies between the local signal from a local oscillator and a reference clock signal from a remote oscillator. A reference counter increments its count for every pulse in the reference clock signal. The value in the reference counter is compared to a configurable reference value. Whenever a match between the reference counter value and the reference value occurs, a hit signal is generated and the reference counter value is reinitialized. Concurrent with the above, a feedback counter increments for every pulse from the local signal. When the hit signal is generated, the value in the feedback counter is compared to a configurable feedback value (by subtraction) to generate a difference value. The difference value is then converted to a frequency adjust signal for use in either increasing or decreasing the frequency of the local oscillator. The hit signal also reinitializes the feedback counter.

    Abstract: This disclosure describes vehicle route calculation methods including "fitting" route segments between locations reported by a vehicle at different times along a route to create an overall "fitted" route. In certain embodiments, a vehicle management system generates a vehicle management user interface that displays the "fitted" route overlaid on a map. The "fitted" route can provide more useful tracking information to an administrator compared to simply displaying direct routes between known route stops.
