Abstract: A method for subsurface radio communication includes transmitting voice data through a subsurface environment, by a transmitter of a radio transceiver. The voice data is received through the subsurface environment, by a receiver of the radio transceiver. A transceiver frequency of the radio transceiver is changed to an optimal transceiver frequency in response to a change to the subsurface environment. The transceiver frequency is one of a transmit frequency of the transmitter and a receive frequency of the receiver. A first impedance of a subwavelength antenna is matched to a second impedance of the transceiver in response to a difference between the first impedance and the second impedance exceeding an impedance mismatch value. The subwavelength antenna has a radiating length less than a transceiver wavelength of the radio transceiver operating in free-space at a maximum of the transceiver frequency.

Abstract: An over-travel mechanism configured to couple an input shaft and an output shaft in an exit device assembly. The input shaft is connected to an actuator that linearly displaces the input shaft, and the output shaft is connected to a locking member of the exit device. The over-travel mechanism includes a link coupled to the output shaft, and a preloaded elastic member transmits force between the input shaft and the link. Movement of the input shaft from a first input shaft position to a second input shaft position causes the elastic member to urge the link from a first link position toward a second link position. Movement of the input shaft from the second input shaft position to a third input shaft position causes the elastic member to elastically deform without moving the link from the second link position.
