  • Patent number: 11143671
    Abstract: In the system and method disclosed, an ultrahigh vacuum (UHV) scanning tunneling microscope (STM) tip is used to selectively desorb hydrogen atoms from the Si(100)-2X1:H surface by injecting electrons at a negative sample bias voltage. A new lithography method is disclosed that allows the STM to operate under imaging conditions and simultaneously desorb H atoms as required. A high frequency signal is added to the negative sample bias voltage to deliver the required energy for hydrogen removal. The resulted current at this frequency and its harmonics are filtered to minimize their effect on the operation of the STM's feedback loop. This approach offers a significant potential for controlled and precise removal of hydrogen atoms from a hydrogen-terminated silicon surface and thus may be used for the fabrication of practical silicon-based atomic-scale devices.

    Abstract: A truncated non-linear interferometer-based atomic force microscope (AFM) includes an input port and a non-linear amplifier that renders a probe beam and a conjugate beam. The AFM includes local oscillators having a relationship with the probe beam and the conjugate beam. The displacement of the AFM's cantilever is transduced by the probe beam, and/or the conjugate beam or their respective local oscillators. The AFM's phase-sensitive detectors detect a phase modulation between the respective local oscillators and the probe beam and the conjugate beam. The detected phase modulation corresponds to the change in phase. The AFM's circuitry measures phase signals that are indicative of the cantilever displacement. The resulting measurement signals exhibit a quantum noise reduction in either the intensity difference or phase sum quadrature.

A configurable light source (12) is controlled by a controller (18) to create a light effect (30, 32) from a first location (34) in front of the individual (22) based on the direction of the individual (22) toward a defined location (36) so as to thereby draw the attention of the user toward said defined location.

  • Patent number: 10527842
    Abstract: A projector includes a mirror quasi-statically driven by a drive signal to scan a laser beam in a pattern. A drive circuit generates the drive signal so the mirror moves in a non-linear fashion, yielding unwanted resonances. The non-linearity results in movement of the mirror through a first projection area, into a dead zone, and into a second projection area. The laser beam is emitted as the mirror moves through the first and second projection areas, but not the dead zone. A controller samples a feedback signal of the mirror as it moves through the first and second projection areas, producing first and second projection area sample which are processed to produce first and second ripple measurements. First and second correction signals are generated as a function of the ripple measurements. The drive circuit applies the correction signals to the drive signal so that the unwanted resonances are attenuated.
