Abstract: A tensional space frame structure for use in decorating, covering, or enclosing spaces, utilizing a plurality of tension members organized to interact with vertical compression members to define a desired shape for the structure and transfer vertical loads to the perimeter of the structure. A large number of configurations for tensional space frame structures exhibit the potential to carry significant vertical loads and are suitable for long-span structures.

Abstract: A system and method for generating a digital pulse width modulation (PWM) control signal for a power transfer device that includes providing a digital PWM signal having a stochastic characteristic, and transforming the digital PWM signal to include control information. A digital reference signal having a stochastic characteristic may be used to provide the PWM signal with stochastic characteristics, and the PWM signal is transformed so as not to lose the stochastic characteristic and stored in a digital storage device. The stored PWM signal exhibits frequency domain characteristics and is configured to minimize undesirable characteristics such as harmonic signatures, audible noise, component vibration, and frequency-domain energy peaks.

Abstract: A method for use in a power converter which includes: monitoring a magnitude of an input of a power-flow controller; generating a pulse-width modulated signal wherein at least one pulse has width correlated with a difference between a reference and the monitored magnitude; and varying an output power flow of the power-flow controller in response to the pulse-width modulated signal. In another embodiment of the method, the power converter is characterized by a power converter selected from the group including but not limited to a power supply, a power controller, and a power regulator. In one or more various embodiments, related systems include but are not limited to circuitry and/or programming for effecting the foregoing-referenced method embodiments; the circuitry and/or programming can be virtually any combination of hardware, software, and/or firmware configured to effect the foregoing-referenced method embodiments depending upon the design choices of the system designer.
