Abstract: A method for designing one or more multichannel, multiband radio frequency (“RF”) pulses for use with a magnetic resonance imaging (“MRI”) system is provided. The method includes determining a number of RF amplitude modulations and a number of RF phase modulations for each channel in a multichannel RF coil by minimizing an objective function that includes a complex-valued vector. The objective function also contains a system matrix that accounts for both a spatial sensitivity profile of each channel in the multichannel RF coil and a magnetic field map for each excitation band in the multiband RF pulse.

Abstract: A luminaire includes a housing having at least one sidewall with an observable outer surface and a light feed edge. The housing sidewall is characterized in that light introduced through a light feed edge of the sidewall will propagate by internal reflections through the sidewall and will be extracted from the outer surface of the sidewall. A fractional amount of light emitted by the luminaire's light source is directed to the sidewall's light feed edge. When extracted, this fractional amount of source light produces an observable and aesthetically pleasing glow of light on the sidewall of the housing.

Abstract: An edge-fed waveguide luminaire includes a light waveguide having a planar body, a waveguide edge support structure, and an anchor opening in the planar body of the light waveguide, which is displaced from said waveguide edge support structure.

The sensor, which will have minimal impact on the aesthetic qualities of the luminaire, is in communication with light switching means for adjusting the light output from the luminaire in response to changes in conditions in the space below the luminaire.

Abstract: A control system includes first and second clutches of a transmission and a control module. Each of the first and second clutches includes an on state and an off state. The control module cycles the first clutch between the on state and the off state using a stepped command signal while the second clutch is maintained in the on state. The control module monitors an output parameter of the transmission that is based on the stepped command signal. The control module controls the transmission based on the output parameter.
