An apparatus for rotating a sensing device about a pan axis and a tilt axis may include an enclosure, first and second rotatable dials configured to allow a user to adjust an angular pan orientation and an angular tilt orientation, respectively, of the sensing device. According to one embodiment, the power detector circuit comprises a chain of amplifiers and a passive mixer. The heat spreader is divided into one or more chambers. The first and second intermediate layers include a porous material and the inner layer includes material substantially impermeable to liquids. Such compounds are represented by Formula as follows:wherein Y, Z, R1, and s are defined herein. The wireless terminal operates to receive datagrams of the second protocol from the remote entity and to transmit the datagrams from the remote entity to the UICC using the first protocol.
