A communications terminal may include: a plurality of antennas; and a transmitter configured to transmit a signal on an antenna of the plurality of antennas, wherein the transmitter further may be configured to transmit a delayed signal on another antenna of the plurality of antennas, and wherein the delayed signal may be generated by delaying the signal by a time delay. The acceleration sensor detects acceleration using a change in capacitance between the movable electrode and the fixed electrodes caused by rotation of the weight portion. In a preferred approach the first electrode has a surface area that is reduced notwithstanding the aforementioned established perimeter. The reset stays active for unselected portions, compensating leakage of a mass of unselected cells which could disturb valid read signals. The two constituent lens elements have at their respective interfaces with air a radius of curvature different from the radius of curvature that they have at the cementing interface. This feature can help enhance the overall efficiency of OEMODM business transaction between the customer and the manufacturer.
