Abstract: Disclosed herein are embodiments of docking frames for protecting the privacy of portable electronic device users against cyberintrusions. An embodiment of the docking frame has a first sidewall for receiving a first side of the device and a second sidewall for receiving a second side of the device. A protrusion extends from at least one of the sidewalls, enough to cover a front-facing camera in the front of the portable electronic device. A sound-reducing material is attached to at least one of the sidewalls to make contact with the electronic device's microphone, so as to muffle sound entering a microphone.

Abstract: A refractory brick assembly unit is provided, including a refractory brick member having an inner passageway extending therethrough from a first opening at an inlet end face to an opposed second opening at an outlet end face thereof. A vector tile is also included, having an annular portion that is coaxially arranged with respect to a longitudinal extension axis of the inner passageway of the refractory brick member positioned in a portion of the inner passageway of the refractory brick member and located proximate the second opening at the outlet end face thereof, and having a domed portion extending from a first surface of the annular portion at a predetermined angle with respect to the longitudinal extension axis of the inner passageway of the refractory brick member so as to occlude at least a portion of the second opening of the refractory brick member at the outlet end face thereof.
