    • A system for measuring exposure to a visual display such as a billboard. A transmitter that is proximate to the billboard broadcasts a data signal that carries information relating to the billboard. This information may identify the location of the billboard, the message displayed by the billboard, and time of day. The data signal is provided at a power level that is adapted to reach a pre-defined exposure area in which the billboard can be viewed. A portable receiving device is provided to a defined consumer population to measure the exposure of the consumers to the billboards. The receiving device may be carried or worn by the consumer, or carried in the consumer's vehicle. The receiving device is adapted to recover the data signal and store the information relating to the billboard when the viewer is in the pre-defined exposure area. The time of day and duration of the exposure may also be recorded. The recorded information is subsequently downloading for processing by a central processing facility, e.g., via a telephone line or computer link.
    • 用于测量诸如广告牌的视觉显示器的曝光的系统。 靠近广告牌的发射机广播携带与广告牌有关的信息的数据信号。 该信息可以标识广告牌的位置,广告牌显示的消息和时间。 数据信号被提供在适于达到其中可以观看广告牌的预定曝光区域的功率水平。 将便携式接收设备提供给定义的消费者群体以测量消费者对广告牌的暴露。 接收设备可以由消费者携带或佩戴,或携带在消费者的车辆中。 接收装置适于在观看者处于预定义的曝光区域时恢复数据信号并存储与广告牌相关的信息。 也可以记录暴露时间和持续时间。 所记录的信息随后被下载以供中央处理设施处理,例如经由电话线或计算机链路。

    • Auxiliary data subband samples representing an auxiliary data signal are transported in a subband-coded compressed digital audio signal without decompressing the data. A pre-existing packetized data stream is provided to an input of a encoder. Subband audio samples are extracted from the packet stream and normalized if required. The data to be transported modulates data carrier subbands including, for example, a pseudo-noise (PN) spread spectrum signal, each subband of which has a bandwidth corresponding to those of the digital audio signal. The data carrier sequence can also include a sparse PN sequence, sample twiddle sequence, or a bit twiddle sequence. The modulated data carrier sequence is combined with the audio subband samples to form a combined signal in which the auxiliary data subband samples are carried. The combined signal is then multiplexed into the pre-existing packet stream. In a decoder, the combined signal is demodulated to recover the auxiliary data signal. The recovered auxiliary data signal is carried substantially inaudibly in the audio signal and is spectrally shaped according to the audio signal to enhance concealment.
    • 代表辅助数据信号的辅助数据子带样本在子带编码压缩数字音频信号中被传送而不解压缩数据。 将预先存在的分组数据流提供给编码器的输入。 从分组流中提取子带音频样本,并根据需要进行归一化。 要传送的数据调制数据载波子带,包括例如伪噪声(PN)扩展频谱信号,每个子带的带宽对应于数字音频信号的带宽。 数据载体序列还可以包括稀疏PN序列,样本旋转序列或位旋转序列。 调制的数据载波序列与音频子带样本组合以形成其中携带辅助数据子带样本的组合信号。 然后将组合的信号复用到预先存在的分组流中。 在解码器中,组合信号被解调以恢复辅助数据信号。 所恢复的辅助数据信号基本上无声地传送到音频信号中,并且根据音频信号进行频谱成形以增强隐藏。

    • Aspects include methods and apparatuses for communicating in an ultra-wideband transmission. For example, some aspects include methods and apparatuses for wireless communications. The method includes, at a first device in communication with at least a second device via a wireless link, monitoring at least one resource for performing at least one function. The method further includes determining whether to assign the at least one function to the at least one second device. The determining is based on information that is indicative of at least function and indicative of at least one resource of the at least one second device. Other aspects include apparatus and devices for communicating data, including according to one or more aspects of the method. For example, some aspects include devices such as headsets, watches, and medical devices configured to use such methods and apparatuses for communicating data.
    • 方面包括用于在超宽带传输中通信的方法和装置。 例如,一些方面包括用于无线通信的方法和装置。 该方法包括在经由无线链路与至少第二设备通信的第一设备处,监视至少一个用于执行至少一个功能的资源。 所述方法还包括确定是否将所述至少一个功能分配给所述至少一个第二设备。 该确定基于至少指示功能并指示至少一个第二设备的至少一个资源的信息。 其他方面包括用于传送数据的装置和装置,包括根据该方法的一个或多个方面。 例如,一些方面包括诸如耳机,手表和被配置为使用这种方法和装置来传送数据的医疗装置的装置。
