Abstract: A circuit and method to filter a signal is provided. The circuit includes a notch filter circuit to receive an input signal and first and second tuning signals and to provide an output signal. The notch filter circuit has an input-output frequency response that includes a stopband region. The stopband region has a center frequency and has an attenuation level that is based at least on a tuning signal. The tunable filter circuit further includes a tuning circuit operable in at least two modes to generate the tuning signal. The at least two modes includes a tuning mode and a filtering mode. The tuning circuit generates the tuning signal such that the attenuation level of the stopband region is greater in the filtering mode than in the tuning mode.

Abstract: A method for generating a candidate assembly system layout for an assembled product includes inputting a bill of materials including a list of components for the assembled product and determining a plurality of assembly patterns for the assembled product including a plurality of intermediate assemblies and sub-assemblies. A basic task layout is determined that includes assembly tasks for assembling the assembled product based upon a selected one of the assembly patterns. A whole task layout is determined based upon the basic task layout for the selected assembly pattern. Candidate assembly machines are selected for the whole task layout, and zoning constraints are identified for the candidate assembly machines related to assembly tasks. A candidate assembly system layout is generated based upon the whole task layout, the selected candidate assembly machines and the zoning constraints, from which a simulation model of a candidate assembly system is generated.

Abstract: A fixture is configured for holding terminals of a battery in alignment. The fixture includes a first and a second side member. The first and second side members each include a plurality of first and second teeth, respectively. The second side member is movable relative to the first side member between an open position and a closed position. The second side member opposes the first side member such that a number of the first teeth oppose a corresponding number of the second teeth and a slit is defined between each of the adjacent teeth when the fixture is in the open position. Likewise, the second side member opposes the first side member such that the number of the first teeth are staggered from the corresponding number of the second teeth to reduce the slit in size when the fixture is in the closed position.

Abstract: A switching regulator IC contains both switching regulator circuitry and an inductor and a capacitor connected in parallel to form a resonant circuit having an associated notch filter frequency response arranged such that, when connected to receive the regulated output voltage, the resonant circuit attenuates the ripple component. This is accomplished by matching the resonant notch to the ripple's fundamental frequency, either manually or automatically. In addition, the resonant circuit's inductor and capacitor can act in concert with decoupling capacitors coupled to the load to form a low pass filter which attenuates harmonics of the ripple's fundamental frequency.
