摘要： An electronic device, such as a digital camera, includes sensors to acquire subject data, such as an electro-optical image, as well as additional sensors to acquire meta-data such as temperature, humidity, the identification of the subject data, and the data and time. The electronic device further includes an image evaluator, to determine the best steganographic method to use to combine the meta-data and the subject data, and a steganographic engine, to combine the meta-data and the subject data in an undetectable manner. In this way, meta-data can be associated with the subject data when the subject data is acquired and in a manner that attaches the meta-data and the subject data without requiring generating and maintaining two, linked data sets.

摘要： A mode of communication for asset tracking units involves communication between a central station and the individual tracking units, usually through a satellite link. This mode is the primary communication link for tracking the assets. A second mode is the local area network (LAN) or "mutter" mode, in which a subset of tracking units communicate with each other in a mobile LAN. This mode is used as the secondary communication mechanism to conserve power, since mutter mode communication requires much less energy for local communication between the tracking units as opposed to direct satellite communication with the central station. In addition, mutter mode leads to increased reliability of the asset tracking system by enabling tracking of units which have batteries too weak to support communication with the central station, but strong enough to support communication in mutter mode. The mutter mode is also useful in finding tracking units which are not communicating with the central station due primary communication equipment fault or other inhibiting condition.
摘要翻译：用于资产跟踪单元的通信模式涉及通常通过卫星链路在中心站和各个跟踪单元之间的通信。此模式是用于跟踪资产的主要通信链接。第二模式是局域网（LAN）或“嘟嘟”模式，其中跟踪单元的子集在移动LAN中彼此通信。该模式用作次要通信机制以节省功率，因为对于与中心站的直接卫星通信相反，跟踪单元之间的本地通信需要更少的能量。此外，嘟嘟模式通过对具有电池太弱的单元进行跟踪以支持与中心站的通信，从而提高资产跟踪系统的可靠性，但足够强大以支持在嘟嘟模式下的通信。由于主要通信设备故障或其他抑制条件，嘟嘟模式也可用于找到不与中心站通信的跟踪单元。

摘要： The present invention provides a novel Geometric Harmonic Modulation (GHM) method. The GHM method functions in two modes, a preamble mode and a traffic mode. During the preamble mode, n+1 frequencies are each offset by a predetermined phase in a transmit unit and passed through a channel to a receive unit. The set of phases is used as the spreading code in the transmit unit, and also acts as an `address` of intended receive units. The receive unit monitors preamble signals to determine the phases. When it recognizes a set of phases, or `address`, which pertains to itself, the receive unit stores the phases and uses these phases to despread and decode the appended message. After the preamble mode is finished, the GHM modulator enters the traffic mode and requests the message to be transmitted from the message source. A traffic carrier waveform is created by multiplying tones, each having its specific phase. An analog or binary message is encoded by modulating the traffic carder waveform. The receive unit detects a preamble carrier and recovers the particular preamble phases to be used as the despreading `key`. The receive unit then employs the phases in despreading the received signal to recover the transmitted binary message.
摘要翻译：本发明提供了一种新颖的几何谐波调制（GHM）方法。 GHM方法在两种模式中起作用，即前导码模式和流量模式。在前导码模式期间，n + 1个频率各自在发送单元中被预定的相位偏移并且通过信道被传送到接收单元。该组相位被用作发送单元中的扩展码，并且还用作预期接收单元的“地址”。接收单元监视前置信号以确定相位。当它识别与本身相关的一组相位或“地址”时，接收单元存储相位并使用这些相位对所附加的消息进行解扩和解码。在前导码模式完成之后，GHM调制器进入业务模式，并请求消息从消息源发送。通过乘以每个具有其特定相位的音调来创建交通载波波形。模拟或二进制消息通过调制业务量卡波形进行编码。接收单元检测前同步码载波并恢复要用作解扩“密钥”的特定前同步码相位。然后，接收单元采用解扩接收信号的相位来恢复发送的二进制消息。

摘要： A signal processor includes a phase looked loop for estimating a largest sine wave component phase and frequency element of an incoming analog signal to provide a component signal and a delta-adjusted subtraction loop for removing a largest sine wave component of the incoming signal. The subtraction loop includes a gain adapter for monitoring an output signal and calculating a gain for minimizing the magnitude of the output signal, a multiplier for multiplying the gain by the component signal to provide a multiplied signal, and a subtractor for subtracting the multiplied signal from the incoming analog signal and supplying the output signal to the gain adapter. The gain adapter in one embodiment includes an algorithm capable of repeating the following sequence during a predetermined period of time: adapting a gain by adding a voltage limit; calculating a present maximum absolute value of a subtracted signal (the output signal) over a measurement cycle; comparing the present maximum absolute value with a previous maximum absolute value and, if the present maximum absolute value is greater, changing the sign of the voltage limit, and adapting the gain by adding the voltage limit; multiplying the voltage limit by a fraction having a value less than one; and changing the previous maximum absolute value to the present maximum absolute value.
