Abstract: A procedure is performed on at least one section of an ocular component. At least one first electro-magnetic radiation is provided to the section so as to interact with at least one acoustic wave in the ocular component. At least one second electro-magnetic radiation is produced based on the interaction. Multiple portions of the second electromagnetic radiation are received. Each portion was emitted from a different corresponding segment of the section. A visco-elastic modulus of the section is monitored based on the multiple portions during the procedure. Feedback is applied to the procedure based at least in part on the monitored visco-elastic modulus, including at least one of: (1) guiding a trajectory of an incision based on different respective monitored values of visco-elastic modulus for the segments, or (2) determining a number of incisions to be made based on different respective monitored values of visco-elastic modulus for the segments.

Abstract: Performing a procedure based on monitored properties of at least one ocular component of an eye includes: performing a procedure on at least one section of a first ocular component of the eye; providing at least one first electro-magnetic radiation to the at least one section so as to interact with at least one acoustic wave in the first ocular component, wherein at least one second electro-magnetic radiation is produced based on the interaction; receiving multiple portions of the at least one second electro-magnetic radiation, each portion having been emitted from a different corresponding segment of the at least one section; monitoring a visco-elastic modulus of the at least one section based on the multiple portions during the procedure; and applying feedback to the procedure based at least in part on the monitored visco-elastic modulus.

Abstract: A sheathed-element glow plug for an internal combustion engine, made up substantially of a plug housing and a glow element disposed in the plug housing, having a gas conduit for measuring the combustion chamber pressure. A gas-permeable filter element, provided according to the present invention in the gas conduit, prevents the penetration of carbon residues or combustion residues into the interior of the sheathed-element glow plug, or reduces particle entry to a tolerable level.

Abstract: For the purpose of metering a flow of gaseous media, there is arranged a perturbation body in a measuring chamber which has a medium flowing through it, and an ultrasonic excitation signal is transmitted through the measuring chamber transverse to the direction of flow and at a point downstream of the perturbation body. The ultrasonic excitation signal after having traversed the measuring chamber is captured together with the ultrasonic excitation signal transmitted as structure-borne noise. The captured signal is squared first and then demodulated with a filter. An indication for the flow through the measuring chamber is derived from the frequency of the demodulated signal.

Abstract: This device comprises an applicator in which the micro-waves are generated. Inside this applicator is disposed a tubular enclosure, preferably coaxial, made from a material inert to the micro-waves which is connected to means for generating a relative vacuum or treatment gas atmosphere. This enclosure is sealed and comprises means allowing the objects to be treated to enter therein or leave therefrom while ensuring the continuity of the seal.
