A system for determining at least one property of a sheet dielectric sample using terahertz radiation includes at least one terahertz transmitter configured to output a pulse of terahertz radiation, a terahertz receiver configured to receive at least a portion of the pulse of terahertz radiation, wherein the terahertz receiver is configured to output a measured waveform based on the terahertz radiation received by the terahertz receiver, and a control unit in communication with the terahertz receiver. Wherein the control unit is configured to choose at least one region of interest of the measured waveform, compare the at least one region of interest of the measured waveform to a model waveform, vary at least one parameter of a model waveform to minimize the difference between the model waveform and the measured waveform.

System for determining at least one property of a sheet dielectric sample using terahertz radiation

A system for determining a material property at an interface between a first layer and a second layer includes a transmitter outputting electromagnetic radiation to the sample, a receiver receiving electromagnetic radiation that was reflected by or transmitted though the sample, and a data acquisition device. The data acquisition device digitizes the electromagnetic radiation to yield waveform data. The waveform data represents the radiation reflected by or transmitted though the sample. The material property to be determined is generally the adhesive strength between the first and second layers.

System and method for detection and measurement of interfacial properties in single and multilayer objects

A system for interpreting terahertz radiation includes a terahertz transmitter configured to output a pulse of terahertz radiation and a terahertz receiver configured to receive at least a portion of the pulse of radiation from the terahertz transmitter. The terahertz receiver is configured to output a signal based on the radiation received by the terahertz receiver.

System for calculation of material properties using reflection terahertz radiation and an external reference structure

A system and method to measure, with increased precision, the transit time position(s) of pulses in a time domain data. An example data set would be the transit time of pulses in Time-Domain Terahertz (TD-THz) data. The precision of the pulse timing directly affects the precision of determined sample properties measurements (e.g., thickness). Additionally, an internal calibration etalon structure and algorithm method provides for continuous system precision/accuracy check method to increase sample measurement integrity. The etalon structure can improve the precision of sample property measurements (e.g., absolute thickness). Various hardware and system implementations of the above are described.

An ultrasonic surgical instrument for dissection and coagulation of tissue is provided. The surgical instrument includes a vibration coupler supported within a housing and operably connected to an ultrasonic generator. An angled blade member is connected to the distal end of the vibration coupler to conduct high frequency vibration from the ultrasonic generator to the blade member. A clamp member is positioned adjacent to the blade member and is movable from a first position to a second approximated position. The clamp member and angled blade member combine to enhance contact between the tissue and the blade member during operation of the instrument to improve the performance of the instrument.

Ultrasonic dissector

A self-inserting absorbable orthopedic fixation device having a bioabsorbable fastening body portion for fastening body tissue, and having bone penetrating elements such as hard, pointed tips for penetrating bone or hard tissue fixed thereto. The pointed tips may be fabricated from metals or ceramics. The fixation device may be in the form of staples, pins, screws, and the like.

Absorbable surgical fastener with bone penetrating elements

A device for delivering a quantity of material endoscopically to an intended site of application within a body through an incision or entrance wound includes a handle portion with movable trigger means, and an endoscopic portion. A reservoir or cartridge containing material for delivery may be disposed in the handle or endoscopic portion of the delivery device. In operation, the trigger means may be operated in such a manner so as to cause a discharge of a metered quantity of material from the proximal end of the endoscopic tube.

Endoscopic material delivery device

A disposable endoscope having an object lens assembly, a relay lens assembly, and an imaging lens assembly with at least the relay lens assembly optical elements being made in whole or in part of molded glass lenses. the relay lens assembly preferably consists of molded glass curved surface lenses arranged in triplet lens configuration with ground or molded glass rod lenses disposed between the curved surface lenses. In preferred embodiments the positive lens elements of each triplet assembly may be bonded in optical contact with the rod lenses or the rod lenses may constitute molded glass lenses incorporating the positive lenses of each triplet. Optical components of the objective and imaging lens assemblies may be of molded or ground glass, and illumination may be conducted by glass or plastic fibers.
