Abstract: A housing encasing a wireless device has at least one opening bordering a display compartment. A pliable retaining lip borders the perimeter of the display compartment and is configured to conform to a portion of an outer perimeter of a removable plate. A portion of the pliable retaining lip is configured to be deformed to enable installation of the removable plate into the display compartment. The display compartment has a compartment recess configured to retain the outer perimeter of a removable plate, whereby, a portion of the removable plate is visible to a user. A transparent barrier element is connected to a surface of the housing and is configured to cover the display compartment. The outer perimeter of the display compartment has a dedicated finger recess for removal of the removable plate.

Abstract: This invention relates to antennas (26, 28, 30 32, 34) comprising an integrated array of antenna elements (36). More particularly, the invention relates to antennas (26, 28, 30 32, 34) in which the array of antenna elements (36) can be reconfigured to suit a multitude of system functions, such as radar, electromagnetic warfare (EW) and communication. Such antennas (26, 28, 30 32, 34) are often referred to as ‘common aperture antennas’ and find use on many platforms including airborne vehicles, ships and boats. An antenna (26, 28, 30 32, 34) is provided that comprises a plurality of antenna elements (36), the antenna (26, 28, 30 32, 34) being operable with sets of the antenna elements (36) organised into first order groups (14, 46) and with sets of first order groups (14, 46) organised into sets of second order groups (18).
