Title: Optical spectrometer
Inventor: Lutz Frommberger
IPC: G01J3/28
Filed: 2020-12-21
Abstract: Optical spectroscopy, e.g. echelle spectrometry using a plasma light source, obtains a sample 101 and blank spectrum 102, e.g. using solution comprising solvent without a sample, or a gas blank spectrum. A cross-correlation of the sample and blank spectra is determined 103, e.g. a phase correlation calculated by computing an fast fourier transform (FFT) of the spectra, taking the complex conjugate of one and multiplying it with the other FFT, before applying the inverse. The blank spectrum is mapped to the sample spectrum based upon the cross-correlation, generating a mapped blank spectrum 105 which is then subtracted to background-correct the sample spectrum 106. The mapping may involve a linear translation based on the peak of the cross-correlation, along with scaling and interpolation. The method may correct for thermal drift between the measurement of the sample and blank spectra, background correcting while reducing introduction of artificial noise.

Title: Four-legged robot having ultra-wide viewing angle
Inventor: XINGXING WANG
IPC: B62D57/032
Filed: 2021-10-25
Abstract: A four-legged robot having an ultra-wide viewing angle. A four-legged robot is equipped with a wide-angle lens or a fisheye lens (2) having a viewing angle that covers a blind area (100) under the robot abdomen, and thus is capable of sensing the terrain under the robot abdomen and obstacles around the robot, achieving ultra-wide vision, and effectively reducing visual blind areas of the four-legged robot. Therefore, the solution can help the robot to select footholds for the feet to prevent the feet from slipping or stepping into pits or holes, or can be used for preventing the feet from hitting obstacles while swinging or for preventing the robot from hitting obstacles around the robot during movement. Thus, the solution prevents loss of control and damage of the four-legged robot, improves the motion sensing capability, and satisfies the requirements for autonomous movement and obstacle avoidance of four-legged robots.
