Latest Patents

**In-situ stress measurement device and method for ultra-deep non-vertical drilling.** This invention uses a bidirectional rolling device and a split-type, axial-force-free circuit switching valve to support single-pipe testing in non-vertical drilling. The rolling device lets downhole equipment move circumferentially and back and forth, replacing sliding friction against the borehole wall with rolling friction. This reduces wear during installation and withdrawal and helps protect impression-measurement markings. The device is intended to support efficient hydraulic-fracturing stress measurements in ultra-deep, non-vertical boreholes.

**Control method for fast trapping and high-frequency mutual ejection of cold atom groups.** This patent describes a method for transferring cold-atom groups between two three-dimensional magneto-optical traps while preparing the next group for trapping. Optical stops create shaded regions along the transfer path. When one group enters the designated region, cooling and repumping light can be activated in the first trap to capture another group, enabling rapid, repeated operation.
