摘要： There is described a method for performing a Raman spectroscopy measurement on a sample. The method generally has sequentially illuminating an area of said sample with first and second excitation signals, said first excitation signal being slightly spectrally spaced-apart from said second excitation signal, resulting in said area sequentially emitting first and second emission signals; upon receiving said first emission signal, measuring a first intensity value being indicative of optical intensity of said first emission signal within at least a detection band; upon receiving said second emission signal, measuring a second intensity value being indicative of optical intensity of said second emission signal within said detection band; and performing said Raman spectroscopy measurement by comparing said first intensity value to said second intensity value.

摘要： An internal fixator apparatus comprises a barrel member having a bone interface adapted to be anchored to a first part of a bone in an extramedullary connection. A piston member has a bone interface adapted to be anchored to a first part of a bone, the piston member including a threaded nut portion, the barrel member and the piston member being operatively connected to concurrently form a joint whereby the barrel member and the piston member are displaceable at least in translation relative to one another. A fixator mechanism is inside the barrel member and the piston member, the fixator mechanism comprising at least a leadscrew threadingly engaged with the threaded nut portion, and at least one magnet connected to the leadscrew to rotate concurrently therewith, the magnet being rotatingly received in the barrel member.

摘要： A method for navigating therapeutic, diagnostic or imaging agents in a vascular network or body cavity is introduced. The method is characterized by high directional gradients and a high magnetic field strength. The latter is used to saturate the magnetization of magnetic therapeutic agents such that when combined with high directional gradients, improved navigation of the magnetic therapeutic agents can be provided at various depths within a patient's body.

摘要： A system and method for imaging a sample using Raman spectrometry. Optical fibers having opposite first ends and second ends are arranged with the first ends and second ends in respective two-dimensional arrays. The two-dimensional arrays maintain relative positions of the optical fibers to one another from the first ends to the second ends in a way that the first end of each optical fibers of the bundle can simultaneously collect a corresponding Raman signal portion scattered from specific spatial coordinates of the area of the sample. The so-collected Raman signal portions are propagated towards the corresponding second end, from which are outputted and detected simultaneously using an array of detectors.

摘要： A mechanical finger has a base adapted to be connected to an actuator for being displaced in at least one degree of actuation, and has two or more phalanges. A first phalanx is rotationally connected at a proximal end to the base, and a second phalanx is rotationally connected at a proximal end to a distal end of the first phalanx. A transmission linkage providing at least one rotational degree of freedom (DOF) between the base and a distal-most one of the phalanges. Passive rotational DOF joints are between the phalanges, between the base and the first phalanx, and in the transmission linkage, whereby the mechanical finger has a passive state of actuation in which the base, the at least two phalanges and the transmission linkage remain in a constant orientation relative to one another through displacement of the base caused by the actuator absent a contact of one of the phalanges with an object, and a grasping state of actuation in which a contact of at least one of the phalanges with an object causes a variation of the orientation of at least one of the phalanges relative to the base through displacement of the base caused by the actuator.
