Abstract: An oven comprising a housing, a cavity located within the housing, and a rotator having a first food loading section and a second food loading section is disclosed. The cavity includes a single opening for loading a food item into the cavity. If one of the first food loading section and the second food loading section is located outside of said cavity, then the other of the first food loading section and the second food loading section is located within said cavity. A first cook setting of the oven when the first food loading section is within the cavity and a second cook setting of the oven when the second food loading section is within the cavity are independently controllable. The first food loading section and the second food loading section may be separated by a divider, which prevents heat from escaping from the cavity through the opening.

Abstract: Simultaneous Multiple Sample Light Scattering systems and methods can be used for polymer stability testing and for applying stressors to polymer or colloid solutions including heat stress, ultrasound, freeze/thaw cycles, shear stress and exposure to different substances and surfaces, among others, that create a polymer stress response used to characterize the polymer solution and stability.

Abstract: A hybrid multi-material outerbelt reinforcement assembly includes a metal body having a first leg and a second leg oriented at an angle with respect to the first leg. The second leg is integrally connected to the first leg defining a junction. A polymeric material reinforcing rib has a rib end contacting the junction and has a rib body extending away from the junction and bisecting the angle between the first leg and the second leg. The reinforcing rib has a rib length extending for substantially an entire length of the metal body. Flanges are integrally connected to the reinforcing rib, each having a first flange portion and a second flange portion each contacting the metal body to mitigate against a torsional rotation of the metal body that increases or decreases the angle of the second leg with respect to the first leg.

Abstract: Digital I and Q (NRZ) data streams are generated by specially configured conversion circuits, the outputs of which are applied to a F-N synthesizer to modulate the synthesizer. All illustrative conversion circuit employs a system of comparators to detect the state of analog I and Q signals at each bit interval and to decode outputs of such comparators to determine the NRZ sequence that gave rise to detected states. Once so determined, these NRZ signals are applied to an F-N synthesizer in the same manner as NRZ signals. Advantageously, inputs to present inventive embodiments may be received either as analog or digital I and Q inputs, subject to selection between input modes using only a single binary input.

Abstract: A fractional sequence generator for use in a F-N synthesizer includes a multi-accumulator structure providing a plurality of carry-out signals for application to an adder through a recombination network to generate an output fractional sequence, S, having an average value given by avg(S)=C/D, where C/D is the desired fractional part of the divisor, and denominator, D, is programmable. Illustratively, contents of a n-bit accumulator in each accumulator is augmented by a function of the programmable denominator value upon a carry-out of the associated n-bit adder in that accumulator.

Abstract: A fractional sequence generator having a plurality of cascaded accumulators whose carry-outs-upon-overflow are provided over a plurality of recombination paths and selective delays to an adder, the pattern of selective delays being modified by the addition of delay elements in all recombination paths except the last to reduce the number of quantization error terms in the transfer function of the sequence generator. Illustrative embodiments may have any number (greater than one) of accumulators and recombination paths, while continuing to exhibit desired simplified frequency response characteristics.

Abstract: A self-tightening shaft coupler includes a rigid, elongate coupling sleeve having an externally compressible collet threaded into each end. The collets engage the ends of the shafts which are to be joined such that the shafts are coupled to one another through the coupling sleeve. The threading of the collets and the coupling sleeve is such that rotation of the shafts in a predetermined direction tends to tighten the collets onto the shafts whereby self-tightening action is achieved.
