A radio frequency transponder includes at least one battery, which is coupled to provide electrical power for operating the transponder and at least one antenna, which is configured to receive and backscatter RF interrogation radiation from an interrogation device. An integrated circuit is arranged to store a code including information and, powered only with energy provided by the battery, to vary a radiation characteristic of the antenna responsively to the code so as to modulate the information onto the backscattered radiation.

A subcutaneous drug delivery device having a housing having an internal reservoir in communication with a drug delivery needle via a fluid path. An expandable chamber disposed adjacent to the reservoir forces drug from the reservoir to the needle when supplied with a gas. A flow regulating chamber, in communication with the fluid path, is capable of volumetric changes in response to temperature and/or pressure changes. An increase in the volume of the flow regulating chamber increases flow resistance to the needle and thereby counteracts the corresponding increase in delivery rate resulting from the expansion of the expandable chamber due to the same volumetric changes in response to temperature and/or pressure. The device also includes an improved filling system that enables the reservoir within the device to be filled with drug from a source without regard to filling position and with a decreased risk of injury from needles. Moreover, the filling system provides an accurate measure of drug transferred into the device thus enabling patients to fill the devices and to ensure proper dosage upon delivery.

The invention is directed to a device for delivering a pharmaceutically active compound or cosmetic substance to a subject comprises a flexible substrate sheet attached to an electronic controller. The controller is provided with a pair of electrical contacts on the underside thereof and is adhered to the sheet by means of a pair of strips of electrically conductive adhesive. The underside of the sheet is printed in two halves with electrically conductive ink to provide a pair of electrodes separated by an insulating barrier. A protuberance extends from each electrode and is folded onto the top of the sheet such that the contacts of the controller are adhered in electrical connection with the protuberances and thus also with the electrodes. The use of an adhesive to connect a controller in electrical communication with the electrodes enables an extremely simple construction of delivery device to be achieved.
