Methods and apparatus for diagnosis of fertility status in the mammalian vagina
Methods and apparatus for interpreting vaginal measurement data by electronic means without the need for the user to take part in the data interpretation process. More specifically, an intelligent probe monitors folliculogenesis and correlates the ovarian function data to probe profile characteristics of the female reproductive cycle. A fertile window is defined with reference to the correlation between folliculogenesis and probe cyclic profiles. Data stored within the apparatus can be downloaded into an external display appliance or data analysis unit. Another aspect of the invention allows for continuous layout of the memory of preceding cycles in the inventory of the apparatus, retaining the most recent while erasing the most distant stored data. These methods assure a reliable fit for the diagnosis of fertility, treatment of infertility as far as timing of treatment procedures, management of subfertility and other gynecological disorders such as luteal phase deficiency or short luteal phase, and the management of premenstrual mood disorders, and of premenopausal and menopausal patients.

System and method for release and dispersion of flies or other biological control
A system and method of release and dispersion of genetically altered flies or other insects to control insect population. The apparatus can be carried by an aircraft and includes removable fly chambers that contain fly containment cylinders. A refrigeration system operates to physically retard the fruit flies. The flies are then released from the fly containment cylinders and fall to the bottom of the fly chamber. Gates on the bottom of the fly chamber are opened manually or remotely to allow the refrigerated flies to fall through the nesting chute into the spiral release controllers. The spiral release controllers dispense the genetically altered flies into the exit chute. The genetically altered flies travel through the exit chute, fall to the earth below and mate with the population thus serving to decrease population by capitalizing on a weakness in the reproductive cycle of the fruit fly or other insect.

Device for interrupting a mosquitos gestation cycle
A device for interrupting the gestating cycle of a mosquito includes a container having a bottom wall and side walls. A generally porous sheet of material is placed over the upper opening thus formed in the container by securing it to the periphery of the container. Double sided tape, mechanical clips, etc. may be used to attach the porous material to the periphery of the container to cover the open area. The porous sheet of material is farametis and contains apertures that are small enough to prevent an adult mosquito from passing through it but yet allow evaporation of water placed into the container and water molecules through the apertures. A sticky substance is placed on the outer surface of the porous sheet. Water is evaporated from the container and water molecules are released through the apertures into the atmosphere above the porous sheet. Gestating mosquito's are attracted to the device and attempt to enter the container to lay there eggs in the water within the container but can not. Instead, the mosquitoes are immobilized on the surface of the porous material when retained by contact with a sticky substance and prevent it from laying eggs in the container or any other body of water. This breaks the reproductive cycle of the mosquito.
