Abstract: A system for determining an ambient concentration of compositions for bathroom cleaning comprises a processor operable to receive a concentration measurement from a sensor over a network within a first period of time. The processor is operable to compare the received concentration measurement to a first threshold and to a second threshold greater than the first threshold. The processor is operable to instruct a memory communicatively coupled to the processor to store an indication that a bathroom was cleaned in response to a determination that the received concentration measurement is greater than the first threshold and less than the second threshold. The processor is operable to send an alert for display on a user device indicating either that the sensor has been tampered or that a spill event has occurred in response to a determination that the received concentration measurement is greater than the second threshold.

Abstract: Acoustic optical integrity detection system architectures and methods can be used to detect optical integrity of an optical component by detecting a discontinuity on and/or in the optical component (e.g., on the optical surface and/or within the bulk of the optical component). In some examples, integrity detection can be used to ensure safety compliance of an optical system, optionally including a laser. Acoustic integrity detection can utilize transducers (e.g., piezoelectric transducers) to transmit ultrasonic waves along an optical surface and/or through the thickness of an optical component. A discontinuity of the optical surface can interact with the transmitted wave causing attenuation, redirection and/or reflection of at least a portion of the transmitted wave. Portions of the transmitted wave energy after interaction with the discontinuity can be measured to determine discontinuity location, type, and/or severity.

An input to the algorithm may include voltage data associated with the voltage generated at the sensor coil. The linear position of the display screen may correspond to a size of the display screen between a minimum size and a maximum size.

Abstract: Lipid suppression in magnetic resonance imaging (“MRI”) is provided on a slice-by-slice basis using tailored local field control that is configured for lipid control for each slice in a planned slice prescription. Only those lipid voxels that fall within the bandwidth of the concurrent RF excitation pulse are targeted. Switched B0 offset fields are used to improve lipid suppression pulse performance by pushing water and lipids apart in the frequency domain. Multi-coil B0 shim arrays with rapidly switchable output currents that can be turned on during the lipid suppression pulse may be used. A convex optimization may be used to jointly solve for the shim currents and the lipid suppression pulse center frequency and bandwidth to optimize lipid suppression while minimizing water signal loss.

Abstract: Nuclear spins are excited in a region of interest in an object under examination by a radio-frequency pulse. During at least one phase of the radio-frequency pulse, excitation fields are transmitted while magnetic field gradients are simultaneously applied so that the magnetization of the nuclear spins moves on a trajectory through a transmission k-space. In a first phase of the at least one phase of the radio-frequency pulse, the trajectory moves at a radial distance around the center of the transmission k-space. The radial distance corresponds to the radius of a sphere superimposed with at least one radial harmonic.
