A digital camera having a camera body and a lens assembly within an imaging unit which is rotatably connected to the camera body. After initial processing of the sense amplifier, testing determines whether the sense amplifier can generate a valid \u201c0\u201d and \u201c1\u201d before programming the eFuse. Of particular interest are compounds of Formula and Formula :Compounds of Formula and Formula are especially suitable for insecticide treated nets and indoor residual spraying for mosquito control. The multi-layer component can optionally be used in combination with the neat dielectric polymer or glass layer and can optionally have interposed metal layers.
