Abstract: Intramedullary nails and other bone stabilization devices are used to provide for bone fixation are made from a biocompatible polymer such as the pyromellitic, dianhydride (PMDA)-free, non-halogenated, thermosetting aromatic polyimide disclosed in U.S. Pat. No. 6,686,437. The intramedullary nails of this invention can be secured to the bone by screws anywhere along their length. The intramedullary nails of the invention eliminate the need for imaging technology, permitting the surgeon more freedom to personalize the operation and support to the needs to the needs of the particular patient and avoid the need to expose the patient and medical personnel to hazardous x-rays and the like. The use of a polyimide polymer instead of a metal device of far higher modulus reduces bone fracturing and splintering and eliminates the risk of metallosis and metal poisoning. Ordinary commercial metal screws can also be exchanged with polyimide self-tapping screws providing a totally non-metal system.

Abstract: A system and method for billing web services provided by a service provider to a user. A server of the service provider is connected to a computerized terminal of the user, and to a telecommunication device of the user via a communication link. The system and method generate codes related to each user, web service and price for using the web service. The server sends the code and receives the code from the telecommunication device. Upon reception the server provides the web service to the user, and bill the price from the account of the telecommunication device.

Abstract: Imbedded in glass vessels like drinking glasses and bottles an electronic device that shines when the glass vessel is moved. The rays of light would travel through the thickness of the glass and/or through the liquid therein. The electronic device is powered by a battery and the movement of the vessel closes an electronic circuit which turns on the light. When the vessel is stationary the electrical circuit is broken so that the light would switch off. The bulb could be a led type or other low power user. There could be a switch accessible from outside the vessel to turn off the possibility of the light shining. In another embodiment the battery, light and other apparatus of this invention would be in an independent base into which a glass vessel would stand. The light effect would be similar as described above when the vessel and the base are tilted and/or otherwise moved.

Abstract: A child's remote control for use with a television (TV) or interactive-TV or cable or satellite box (converter) comprises enlarged keys and/or color-coding according to function group. The enlarged keys provide a wider top surface and area between the keys, making the present invention easy for the use of children and infants.
