  • Patent number: 11497935
    Abstract: A tandem applicator assembly for brachytherapy that includes a tandem and a camera system. The tandem has a tubular main body with a trail end and a lead end. A transparent cap is affixed to the lead end. The camera system is removably received by the tandem through the trail end of the tubular main body. The camera system is disposed inside of the transparent cap. The camera system includes at least one digital camera configured to acquire color images from a patient through the transparent cap. The tandem applicator assembly may be used with a treatment planning system and method for customizing a treatment plan for a patient undergoing brachytherapy.

  • Patent number: 9894854
    Abstract: A liquid storage and delivery system includes a reservoir and a storage container. The storage container has a main body with a hollow interior, and is configured to hold a reserve volume of the water. The main body has an upper wall and a lower wall. The hollow interior is disposed between the upper wall and the lower wall. A refill conduit is in communication with the hollow interior of the storage container. An air conduit is in communication with the hollow interior of the storage container and the reservoir. A liquid passage is in communication with the hollow interior of the storage container and the reservoir. The liquid passage is configured to deliver the water from the storage container to the reservoir. The liquid storage and delivery system is particularly useful for the watering of plants and animals.

  • Patent number: 5323166
    Abstract: A device and method for reconstructing a vector wave and its source direction by measuring the amplitudes of the vector wave in directions chosen according to a necessary and sufficient condition that ensures that the measured amplitudes contain enough information to provide a unique set of relative phases among the sinusoidally time-varying components of the vector wave. Together with the amplitudes, these relative phases are processed by a microprocessor to yield the polarization characteristics of the vector wave and the direction of its source.
