Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: A filter holding frame has two or more vertical walls coupled to two or more horizontal walls forming a rectangular frame. A flange extends inward from a back edge of each wall. At least one of the two or more vertical walls or one of the two or more horizontal walls has one or more retaining features. The one or more retaining members are coupled to the retaining features. The retaining members forming a compression catch. The compression catch has a body having a first end and a second end fixedly coupled to the retaining feature of the holding frame and a retaining portion. The first end and second end extend in the same direction to the retaining portion. The retaining portion has a bow shape to form a spring element, wherein the retaining portion is configured to bias a filter against the flange.
