The energy harvesting devices can also harvest their power from these ambient broadcast wirelesses TV signals. The usage of cross-polarized antenna MIMO scheme allows the video signals to be carried over multi-carrier frequencies via OFDM at much wider bandwidth in the UHF bands. The electronic devices operating at 3V or less than 3V can also be used to scavenge their power from such type of broadcasting by means of a dipole antenna. The condition is that the dipole should lie within a range of 6.5km from the source.

For many AVMs, microsurgical resection is the treatment of choice. It offers immediate elimination of hemorrhage risk, treats the symptoms of vascular steal, and often improves seizure control for those patients presenting with a seizure disorder. Certain AVMs, however, are inoperable due to their large size, eloquent location, deep venous drainage, and/or other anatomical considerations that are associated with unacceptably high rates of morbidity and mortality. For these lesions, alternative therapies such as SRS and endovascular embolization are often considered. Small AVMs (≤ 3 cm in maximum diameter) are Combined endovascular embolization and stereotactic radiosurgery in the treatment of large arteriovenous malformations Clinical article
