    • A two dimensional display panel produces a time variable image composed of light emitting pixels. The pixels are generated by a light emitting phosphor distributed within the panel, the pixels radiate light in response to being excited by charging and triggering energy beams. The energy beams are relatively invisible and may be generated by lasers or solid state diode energy sources. Wave guides within the panel direct the energy beams to the pixels. The wave guides may be composed of fiber optic threads and the display panel comprised of a fabric of woven fiber optic threads wherein pixels are produced at intersections of the woven fiber optic threads. The brightness of the pixels are controlled by regulating the duty cycle of a column driver relative to the duty cycle of a row driver. The display energy beams are driven to facilitate interface with a pen-like pointing device. In one embodiment the pen receives relatively invisible energy beams and in another embodiment the pen receives visible pixel light. In another embodiment, the invention has redundant energy beam sources and driving circuitry in order improve display system reliability.
    • 二维显示面板产生由发光像素构成的时间可变图像。 像素由分布在面板内的发光荧光体产生,像素通过对能量束进行充电和触发而被激发。 能量束相对不可见,并且可以由激光器或固态二极管能量源产生。 面板内的波导将能量束引导到像素。 波导可以由光纤线组成,并且显示面板包括编织光纤线的织物,其中像素在编织光纤线的交点处产生。 通过调节列驱动器相对于行驱动器的占空比的占空比来控制像素的亮度。 显示能量束被驱动以便于与笔状指示装置的接口。 在一个实施例中,笔接收相对不可见的能量束,并且在另一实施例中,笔接收可见像素光。 在另一个实施例中,本发明具有冗余能量束源和驱动电路,以提高显示系统的可靠性。

    • A radio communication device (100) for tracking peaks and valleys of a signal received by a receiver (110) includes tracking circuitry (115) for approximating the peaks and valleys by attacking and decaying values stored in peak and valley counters (124, 132). When the tracking circuitry (115) is in a fast track mode, a peak/valley controller (120) decays a stored value by a first amount when the stored value exceeds a sampled signal voltage and attacks the stored value by a second amount when the stored value does not exceed the sampled signal voltage. The first amount is greater than the second amount. Preferably, the counters (124, 132) are eight-bit counters, the first amount equals eight, and the second amount equals four.

    • A magnetically communicative card (200) has a ferrite core (302) extending substantially the length of the card body (203) and has a conductor (408) wound around the ferrite core for the entire length of the ferrite core. Embedded within the card body is a controller (208) that controls a varying magnetic field emanating from the conductor to mimic a varying magnetic field produced by a conventional magnetic stripe card. Optionally, the card includes a sensor to sense a sensed signal picked up by the conductor from a varying magnetic field emanating from another device. The controller can read the sensed signal to receive communication from the other device. A magnetically communicative card (400, 500) is alternatively flexibly attached and detachably coupled to an electronic wallet (402, 502) to produce an apparatus (405, 501). A wireless communication interface (523) is alternatively carried by the magnetically communicative card and the electronic wallet to provide wireless reconfiguration of the magnetically communicative card remotely.

    • A paging receiver receives a message signal having an address field and a data field. The message has at least one address within the address field and a plurality of packets in the data field. The data packets contain a predetermined amount of information. A method for conserving power during reception of a message signal having an address field comprising a number of addresses involves entering the power conserving mode of operation after attempting to correlate a predetermined number of addresses with the paging receiver's address, where the predetermined number is less than the number of addresses in the address field. In addition, message information may be included within a plurality of packets by several methods including placing a corresponding plurality of addresses in the address field, each address indicating the occurrence of message information, or by indicating in one packet that information follows in a subsequent packet. Use of the second method provides for placing of tone only messages in positions left vacant in the address field by the subsequent data packets. Additionally, the invention provides for varying the size of the address field with a boundary signal.
