Abstract: A method and device for detecting the amplitude and/or the phase position of an intensity-modulated signal, including the following: detecting an instant value of the intensity-modulated signal and of a first reference signal with a frequency differing from the intensity-modulated signal; mixing the first reference signal with the intensity-modulated signal to obtain a mixed-signal value; detecting an instant value of a second reference signal with a frequency differing from both the previously detected signals and of a third reference signal of the same frequency but phase-shifted from the second reference signal; mixing the mixed-signal value with the second reference signal to yield a first measurement value; mixing the mixed-signal value with the third reference signal to yield a second measurement signal value; and calculating the amplitude and/or phase position from the two measurement signal values.

Abstract: Spectral, densitometric, or color measured values are detected on sheet printing materials during the printing process in a sheet-fed printing press. The measured values are determined on sheets as they are moving through the printing press and the measured values are used in real-time by a computer to control parameters for controlling the printing process in the sheet-fed printing press.

Abstract: An instrument of an instrument set is used to insert an implant into a disc space. The implant comprises a first cage and a second cage and the instrument comprises a distal end configured to push the cage first inserted into the disc space laterally in its proper anatomical location. Said distal end of the instrument has a tip, which is curved and has a curved inner side configured to contact an outer curved side of the first cage. The instrument set allows the insertion of two cages through a relatively small incision in the interdisc space in a simple jet safe procedure.

Abstract: The cylindrical fiber reinforced implant is designed to be inserted between two adjacent vertebrae. The implant having an outer wall with a general cylindrical or oval shape and preferably an open volume for bone filling. Said wall having reinforcing fibers which at least in part are oriented in a first direction. A support extending within said volume having reinforcing fibers which are at least in part oriented in a second direction, said first and said second directions are different. Preferably the fibers of the outer wall are at least partly concentrically oriented. The support is preferably a separately formed part, that is inserted into the outer wall.

The structure is made of a composite material having reinforcing fibers, and has a first and second face to engage adjacent bone structures to be fused, struts extending between the first and second faces, and a hollow interior space for reception of bone growth inducing substances. The fibers are long fibers and the majority of these long fibers have a direction that follows the longitudinal forces upon the first and second faces, which is the direction of trabecular structures of the adjacent bone structure, so that a majority of long fibers are essentially an extension of these trabecular structures.

Abstract: A device and method for spatially resolved photodetection and demodulation of temporally modulated electromagnetic waves makes it possible to measure phase, amplitude and offset of a temporally modulated, spatially coded radiation field. A micro-optical element (41) spatially averages a portion (30) of the scene and equally distributes the averaged intensity on two photo sites (51.1.51.2) close to each other. Adjacent to each of these photo sites (51.1) are two storage areas (54.1, 54.2) into which charge from the photo site can be moved quickly (with a speed of several MHz to several tens or even hundreds of MHz) and accumulated essentially free of noise. This is possible by employing the charge-coupled device (CCD) principle. The device combines a high optical fill factor, insensitivity to offset errors, high sensitivity even with little light, simultaneous data acquisition, small pixel size, and maximum efficiency in use of available signal photons for sinusoidal as well as pulsed radiation signals.

Abstract: The present invention relates to a method for detecting the amplitude and/or phase position of an at least partly intensity-modulated signal (PE(t)), and a corresponding device for carrying out the method.

Abstract: The pair of lumbar interbody implants is designed to be pushed laterally in a space between adjacent vertebrae for replacing the disc between these vertebrae. Each implant comprises a first and a second saggital wall and an anterior wall at one end and a posterior wall at the other end. The two implants are asymmetric to each other and are therefore more appropriate for the transforaminal lumbar interbody fusion. Preferably a first implant has a first saggital wall with an outer surface that is curved and a second saggital wall that is essentially plane.
