    • An ambient electromagnetic energy collector has a magnetic core of high permeability ferromagnetic material wrapped in an inductor coil for coupling primarily to a magnetic field component of a propagating transverse electromagnetic (TEM) wave. For coupling to electromagnetic waves of a wide range of frequencies and magnitudes, the collector is coupled to a multi-phase transformer connected to a multi-phase diode voltage multiplier to provide a current source output to an associated energy storage device. An output controller supplies output power as needed to the associated energy-using device. Preferred types of ferromagnetic materials include nickel-iron alloys with a small percentage of silicon, molybdenum, or copper. It may be combined with other types of ambient energy collectors, such as acoustic/vibration, thermoelectric, and photovoltaic collectors, in a multi-source device provided with a collector interface for converting the different outputs for storage in a common energy storage device. The multi-source ambient energy collector device can be used to supply power to embedded devices, remotely deployed wireless sensors or RFID tags, and other types of monitoring devices distributed over large areas or in industrial environments.

    • The present invention provides such a need by utilizing a frequency offset differential pulse position modulation scheme to transmit data between computing devices within a wireless network system. The differential pulse position modulation component of the scheme enables the present invention to provide relative immunity to interference for the system. In particular, such immunity from interference is achieved by utilizing a blanking time between pulse positions, which is large enough to allow the interference between frequency offset—differential pulse position modulation pulses to subside. The frequency offset component of the scheme enables the system to utilize multiple frequency channels to enable the system to achieve higher data rates. In particular, by utilizing a time offset between the frequency channels, the blanking time can be reduced, thereby increasing the amount of data that can be transmitted with a set period of time.
    • 本发明提供了通过利用频率偏移差分脉冲位置调制方案来在无线网络系统内的计算设备之间传输数据的需要。 该方案的差分脉冲位置调制组件使得本发明能够提供对系统的干扰的相对抗扰性。 特别地,通过利用脉冲位置之间的消隐时间来实现这种抗干扰性,其足够大以允许频率偏移 - 差分脉冲位置调制脉冲之间的干扰消失。 该方案的频率偏移分量使得系统能够利用多个频率信道来使得系统能够实现更高的数据速率。 特别地,通过利用频道之间的时间偏移,可以减少消隐时间,从而增加在一段时间内可以发送的数据量。

    • Paper is made by providing an anionic aqueous emulsion of a size, usually a reactive anhydride size, and mixing it into a cellulosic suspension prior to drainage of the suspension to form a sheet which is then dried to provide paper (including paper board). The emulsion is preferably stabilised wholly or mainly by 0.5 to 30 parts by weight (per part by weight size) of water soluble, anionic, polymeric stabiliser, which is preferably anionic starch. Alternatively, the emulsion may be added to the cellulosic suspension while it is anionic, before mixing retention into it. The emulsion may be added to the cellulosic suspension after cationic retention aid has been added to it, the emulsion being added with, before or after mixing anionic microparticulate material or other anionic bridging aid, prior to drainage of the suspension.
    • 纸通过提供尺寸(通常为反应性酸酐尺寸)的阴离子水性乳液制成,并在悬浮液排出之前将其混合到纤维素悬浮液中以形成片材,然后干燥以提供纸张(包括纸板)。 乳液优选完全或主要稳定为水溶性阴离子聚合物稳定剂0.5-30重量份(按重量份计),其优选为阴离子淀粉。 或者,可以将乳液在阴离子之前加入到纤维素悬浮液中,然后将保留物混入其中。 在向其中加入阳离子助留剂之后,可以将乳液加入到纤维素悬浮液中,在混合阴离子微粒材料或其它阴离子桥联助剂之前或之后,将乳液加入到悬浮液排出之前。
