    Abstract: A multiple solar cell having at least two partial cells, at least being formed from a direct semiconductor, having an upper partial cell facing the light and a lower partial cell facing away from the light, an upper bandgap of the upper partial cell being greater than a lower bandgap of the lower partial cell, and an intermediate layer arranged on the lower partial cell side facing away from the light. An optical element including a lower mirror element is arranged on the intermediate layer side facing away from the light, and has a partial element having structural elements arranged in a lateral direction on the intermediate layer side facing away from the light. The structural elements have a mean spacing less than or equal to 1.3 times a spacing value that results from a ratio of a wavelength of the lower bandgap to a refractive index of the lower partial cell or the lower mirror element has a roughness having a root-mean-square value of less than 50 nm.

  • Patent number: 11598195
    Abstract: A method for estimating a probability of a drilling dysfunction or a drilling performance indicator value occurring includes entering drilling-related data having a probability distribution into a mathematical model of a drill string drilling a borehole penetrating the earth and entering drilling parameters into the model for drilling the borehole. The method further includes performing a plurality of drilling simulations using the model, each simulation providing a probability of the drilling dysfunction occurring or a probability of a drilling performance indicator value occurring with associated drilling parameters used in the simulation, selecting a set of drilling parameters that optimizes a drilling objective using the probabilities of the drilling dysfunction occurring or the probabilities of a drilling performance indicator value occurring; and transmitting the selected set of drilling parameters to a signal receiving device.

  • Patent number: 9816368
    Abstract: An apparatus for drilling a borehole into an earth formation includes: a drill bit configured to be rotated to drill into the formation; a drill tubular coupled to the drill bit and configured to rotate the drill bit; a steering device coupled to the drill string and configured to impart a force on the drill string to control a direction of drilling; and a controller configured to communicate a control signal to the steering device. The control signal includes information for directing actuation of the steering device for steering the drill bit in an intended drilling direction. The controller is further configured to direct the steering device to provide a compensating force on the drill string that prevents or reduces an azimuthal deviation from the intended drilling direction due to drill bit walking.
