Abstract: The device, for use in contraception and in preventing transmission of sexually transmitted diseases, comprises a thin, flexible pouch 1 having an open end 2 in the form of a peripheral flange with a periperal ribbed rim 3, and a closed end 4. An insert 17 is provided within the closed end 4 of the pouch so as to protect the pouch during insertion thereof into the vagina by means of an applicator rod 15 or the like. The insert 17, which is typically absorbent and of flexible expanded plastics material, and may have dispersed therein a spermicide and/or an antiviral agent, comprises a central portion 18 and (extending radially outwardly from central portion 18) four spurs 20a, 20b, 20c, 20d. A continuous coating layer of an adhesive material which can temporarily adhere the barrier device to mucous membrane material in the presence of aqueous body fluids is preferably provided on the vulva-contacting surface of the flange and/or on the vagina-contacting surface of the pouch.

Abstract: An interactive toy is capable of detecting and tracking any nearby heat source such as a human body. This device can, in addition to tracking, move to interact with the heat source. The toy can either chase or move away from the heat source according to a set mode of operation. PIR sensors are mounted in a rotating head that is mounted in turn upon a wheeled, tracked or legged body that can move. The device further includes sensors to detect unheated objects in its path and will act to avoid hitting them. The PIR sensors have a limited field of view so as to prevent overlapping fields of view and are filtered or tuned to receive only a certain bandwidth or infrared radiation.
