Abstract: An antenna apparatus comprises an additively manufactured body having a back surface with one or more flat regions and a substantially convex front surface opposite the back surface, as well as one or more of any of the following: a radiative antenna element attached to the front surface; a radiative antenna element integrated into or near the front surface via additive manufacturing; a passive electrical filter component integrated into the body via additive manufacturing; and an electrically conductive trace integrated into the body via additive manufacturing and arranged to provide an electrical connection from the back surface of the body to the front surface of the body or to a passive electrical filter component integrated into the body.

Abstract: Systems and methods of interconnecting electrical devices are provided. In one exemplary embodiment, an arrangement of interconnected electrical devices may include one or more first electrical devices with a first data flow and one or more second electrical devices with a second data flow. Further, the first electrical devices may be mirrored versions of the second electrical devices. Also, the first data flow may be substantially opposite to the second data flow.

Abstract: An integrated circuit having a first security operation state arranged for utility operation, and a second security operation state arranged for test operation is disclosed. In the second security operation state, a first set and a second set of objects are available, while a third set of objects are unavailable. In the first security operation state, the third set of objects is available with authorization by a security mechanism of the first security operation state. The third set of objects is made unavailable by logic circuitry of the integrated circuit, when operating in the second security operation state, by the logic circuitry being arranged to control limited operation of parts of the integrated circuit comprising the third set of objects when operating in the second security operation state such that bypassing of the security mechanism of the first security operation state is disabled. An electronic apparatus utilising such an integrated circuit, and a method are also disclosed.
