Abstract: The present invention relates to a reusable water writing paper, as well as to its production process and an inkless printing device thereof. The reusable water writing paper is consisted of a substrate as structure-support material, a color-displaying component supported on the substrate, and an optional performance-enhancing additive, wherein the color-displaying component is an oxazoline-based hydrochromic dye, which can change color obviously to display characters and/or patterns after contacting with water, and revert to the initial color to disappear the displayed characters and/or patterns after the water is removed, thereby the water writing paper is reusable. The paper is not only suitable for the exercise of writing or drawing with a brush pen, but also can be used for daily writing with a pen. Furthermore, inkless printing also can be achieved by spraying water.

Abstract: A cable connector assembly comprises an electrical connector and a cable connected to a rear side of the electrical connector. The electrical connector comprises an insulative housing and a plurality of conductive terminals fixed thereto. The cable comprises a plurality of wires, a filler among the wires and an insulative covering which covers outer peripheries of the wires and the filler. The wires and the conductive terminals are electrically connected. The cable connector assembly further comprises an inner mold and a casing surrounding an outer periphery of the inner mold. The inner mold is integrally formed at outer peripheries of connections between the conductive terminals and the wires by over-molding. A part of the filler is embedded into the inner mold for stress relief.

Abstract: A wireless telecommunication device conducts base station pages at large intervals, such as 30 seconds, rather than the more conventional 0.5 to 4 seconds. The network processes calls placed to that telecommunication device in accordance with an SMS (Short Messaging Service) type protocol rather than a conventional voice call protocol. Particularly, the network sends an SMS to the telephone indicating that a third party is calling (hereinafter termed a “pre-call SMS”). The pre-call SMS indicates the telephone number of the third party. The user of the telephone may call the third party back. In accordance with this protocol, the need to page at very short intervals so as to permit a telephone call to be established in “real-time” is eliminated. Therefore, the paging interval can be increased substantially, thereby substantially prolonging battery charge lifetime of the telephone.
