摘要： A medical device for photodynamically treating cancerous tissue, such as prostate cancer, comprising a body, a needle extendable from the body and at least one light-emitting (e.g., laser) diode mounted on the needle. The body is sized and configured for introduction into the urethra of a patient. The needle is movable between a retracted position housed substantially within the cylindrical body, and a deployed position in which the needle extends from the cylindrical body to enable it to penetrate into prostate tissue. The light-emitting diode is adapted to emit light to activate a photosensitizing agent (e.g., porfimer sodium) in or adjacent cancerous tissue in the prostate. Methods of treating cancer and other embodiments of medical devices for cancer treatment are also disclosed.

摘要： This invention provides a method for soldering using induction heating, which is accomplished by the use of lossy heating particles in or on the solder. The method of this invention provides direct heating of the solder itself through induction heating of the magnetic particles in an alternating magnetic field. The magnetic particles useful in this invention can be ferromagnetic particles or ferrimagnetic particles, preferably ferrites, which have a Curie temperature at least equal to the flow temperature of the solder. Selection of the magnetic lossy heating particles with the appropriate Curie temperature for the system in which the particles are being used provides a system in which the temperature is self-regulating when the alternating magnetic field is applied. This self-regulation feature prevents overheating of the solder in the articles being soldered. The invention also discloses the selection of particles with surface properties whereby the particles can either be wetted by the solder and remain in the solder when the solder flows or it can be nonwettable by the solder whereby the particles separate from the solder when the solder flows. The surface properties can also be provided by coatings on the particles. This invention also discloses solder compositions comprising solder and lossy heating particles which produce the desired heat in an alternating magnetic field. The invention also provides systems and assemblies for the use of the above method and composition.

摘要： Vehicle lighting system consisting of a vehicle with an integral light source powered either internally by an on-board energy source such as a rechargeable capacitor or a battery. In another embodiment the light source may be powered by an external energy source such as electrical conductors that may be integral with a track. The light source in the vehicle interacts with features on the track. The track acts as a light reflecting and emitting medium so that it accepts the light transmitted from the vehicle, redirects the light rays and emits the light rays in the direction desired. These light rays can be continuous in nature and output or can be discontinuous. The discontinuous feature gives the impression of a pulsing light and this pulsing light is proportional to the vehicle's speed. This particular lighting system and track interaction can be used for children's toys or even larger full scale vehicle systems where it might be desirable to actually be able to track the vehicle and determine the speed of the vehicle from an outside observer.
