This specification describes various embodiments that relate to methods for providing a wideband colorimeter that can include more accurate outputs. The package has a continuous, elongated design with a circular, elliptical, square, rectangular or polygonal cross section. A check valve is arranged to close in order to prevent product, upon compressing the hose member, from flowing back from the hose member to the container, and a discharge valve is arranged to open so as to allow dispensing of product from the hose member and to close when so done. An injector assembly is disposed within the body and coupled to the fuel inlet. A software reliability model is selected according to the testing results profile. When a transmitting and receiving module for use in a radar system is formed by using the dielectric resonator oscillator, the system can be formed at low cost and the maximum distance to an object which can be detected can be increased.
