Therapeutic devices that provide support or pressure to tissue. Devices contain a material that is capable of being contracted from its relaxed state to an evacuated state. The material applies pressure to the tissue of a patient when the material is in its relaxed state. Reduction of pressure by application of a vacuum results in a contracted state of the device, so that the device can be applied or delivered to a patient. Release of vacuum results in a return to the relaxed state, thus providing a maximum desirable pressure to tissue and avoiding the possibility of over-pressure which can result in tissue damage or necrosis.

Tracking tags for attachment to an object or animal. The tracking tags may include low-power long-range transmitters drawing power from a battery or a renewable energy source. The tracking tags may also each include a microcontroller having a sleep-mode module enabling nearly no quiescent current to be drawn when the microcontroller is in a sleep-mode. The microcontroller may enter into a sleep-mode for long periods of time following a short period of sending data to the low-power long-range transmitter. The short period of sending data may be approximately one-twentieth of the long sleep-mode period. The tracking tags may also include sensors for determining an ambient temperature or biometric data about an animal to which the tracking tag is attached. Locations of the tracking tags may be determined using signal trilateration and/or signal triangulation.
