Surgical microscope with gesture control and method for a gesture control of a surgical microscope
The present invention relates to a surgical microscope (1) with a field of view (9) and comprising an optical imaging system (3) which images an inspection area (11) which is at least partially located in the field of view (9), and to a method for a gesture control of a surgical microscope (1) having an optical imaging system (3). Surgical microscopes (1) of the art have the disadvantage that an adjustment of the microscope parameters, for instance the working distance, field of view (9) or illumination mode, requires the surgeon to put down his or her surgical tools, look up from the microscope's eyepiece (5) and perform the adjustment by operating the microscope handles.

Spectrum monitoring
Approaches provide for determining spectral information for a communications signal, such as a wideband communications signal. For example, a communications signal (e.g., a wideband signal) is received at a set of analog-to-digital converters (ADCs). The output of the ADCs is divided into a set of segments. A center frequency for each segment is determined based on the segment bandwidth and a number of segments in the set. The segments can be filtered, buffered, and analyzed using at least one digital signal processing technique (e.g., Fast Fourier Transform (FFT) technique to generate a representation of the segments in the frequency domain. Thereafter, the spectrum of frequency components (i.e., the frequency-domain representation) of the segments can be used to determine the power spectral density of the communications signal for different resolutions based on a resolution mode of the system or other criteria of the system. |

Generally, when antennas are configured to transmit at two or more different bands or frequencies, particular combinations of frequencies can introduce passive intermodulation at one of the corresponding receive bands or frequencies. Passive intermodulation is exacerbated, in some instances, due to the presence of non-linearities in the RF path. Embodiments can be configured to automatically detect the presence of passive intermodulation in one of the receive bands or frequencies and dynamically mitigate the affected receive signal to maintain optimal system performance. |

Methods and apparatus for tracking moving objects using symmetric phase change detection
An optical receiver including an optical resonator and a steering mechanism coupled to the at least one optical resonator is disclosed. The optical resonator is configured to receive a phase modulated input optical signal and to produce an intensity modulated output optical signal. An intensity modulation of the output optical signal is representative of the phase modulation of the input optical signal. The optical receiver further comprises an optical-electrical converter that detects the intensity modulated output optical signal and converts the intensity modulated output optical signal to an electrical signal, and signal processor that receives the electrical signal, performs symmetric phase change measurements based on the electrical signal, and provides a control signal to actuate the steering mechanism to steer the optical resonator to maintain normal incidence of the phase modulated input optical signal on a surface of at least one optical resonator. |
