摘要： An optical fiber device for allowing local measurement of temperature or strain using pulse amplitude techniques. The apparatus includes a fiber splice having a high temperature epoxy or solder to secure the opposing fibers in spaced relationship within a metal tube. By applying heat or stress to the tube the load causes the air gap to open or close which in turn varies the amount of light transmitted. By utilizing apparatus to measure the change in the amplitude affected by changes in the air gap, one can measure ultimately the strain or temperature imposed on the device.

摘要： The present invention pertains to an optical splice. The optical splice includes a member having an alignment cavity which receives optical waveguides and allows light to pass there between. The member is made of a material that is moldable such that when an optical waveguide is received by the member, the alignment cavity expands but constricts about the optical waveguide in a predetermined position. The member has a plurality of funnels which communicate with the alignment cavity and guide an optical waveguide into the alignment cavity where it is received thereby. The present invention also pertains to a method for making a funnel in a member. The method includes the steps of placing a drawn-down end of a capillary into a mold; inserting an alignment rod into the mold and the capillary through the drawn-down end thereof; filling the mold with a curable material; allowing the material to cure to form the member; and removing the alignment rod and capillary from the member to form in the member an alignment cavity with a funnel. In a preferred embodiment the member is an optical splice.

摘要： An electrostatic self-assembly method of fabricating electrostrictive and piezoelectric thin film assemblies not only provides a thinner film than is attainable by conventional methods, but provides excellent molecular-level uniformity and precise structural control, and thus large, effective piezoelectric coefficients. The method produces a thin film assembly including (a) a substrate, and (b) a film having one or a plurality of layers disposed upon the substrate, wherein at least one of the layers includes a dipolar material, and this layer of dipolar material has a uniform thickness of at most 500 nm.

摘要： A piezoelectric crystal with several concentric ring electrodes on one side of the crystal. A resistor network applies different amplitudes of an AC source to each of the several electrodes. A plot of the different amplitudes from the outermost electrode to the innermost electrode is the first half of a Gaussian function. Consequently, the output of the crystal from the side opposite the electrodes has a Gaussian profile.

摘要： A robot gripper control system is disclosed which uses PVDF piezoelectric sensors to actively damp exerted force. Instead of charge amplifying the output of the piezoelectric transducer, the output voltage is measured as the charge drains across a path of low resistance. Thus, the sensor output is proportional to the rate-of-force exerted by the gripper. The PVDF sensor and a strain gauge are arranged in a proportional and derivative (PD) control system for the control of force of a robot manipulator hand. Experimental results for the particular disclosed gripper indicate that as much as 900% improvement in force step response rise time and a 300% reduction in overshoot are possible through the use of the PVDF sensor.

摘要： A modal domain optical fiber sensor for vibration monitoring and as a mechanical motion detector. A laser that focuses coherent light through a lens into one end of a multimode optical fiber. The fiber is secured to a mechanical mechanism for exciting vibrations. The other end of the optical fiber passes its output through a spatial filter and into a photodetector. A variable voltage signal from the photodetector is fed to a monitoring unit, such as an oscilloscope or a microcomputer, for analysis. Of particular significance is the intentional mismatch between the wavelength of the light 18 from the laser and the single mode cut-off wavelength of the glass optical fiber. In a preferred embodiment, the optical fiber has a wavelength of 850 nm and the coherent light has a wavelength of 633 mm.

摘要： A communication network and method implementing a star-tree topology utilizes conventional hardward and the CSMA/CD protocol. The network comprises in one embodiment at least two sets of user devices, in turn comprised of at least two user devices, connected through optical connectors and intelligent hubs to one another. Within each set of devices, the devices themselves are connected together by optical connectors through an optical coupler and an intelligent hub.The method according to one embodiment involves the steps of assigning unique addresses to each hub and subhub in the network and of assigning a device address to each user device. The device address need only be different from the addresses of the other devices in the family. The messages are sent from any one station through a passive coupler to all the other stations connected thereto. If an exclusive OR situation exists whereby either but not both the subhub of the family is the source subhub or the destination subhub then that subhub copies the message and rebroadcasts the message either to its own family or to its parent.

摘要： A device includes a nanocomposite film, itself, having at least one nano-particle layer and at least one crosslinker layer. The device also includes an abrasion resistant coating over the nanocomposite film. A method for producing a device with an abrasion resistant nanocomposite coating on a substrate having a nano-particle-coated surface involves contacting nano-particle-coated surface with a crosslinker such that a chemical bond forms with nano-particles within the nano-particle-coated surface and this chemically bonded crosslinker is then contacted with at least one compound such that the at least one compound chemically binds to the crosslinker thereby forming an abrasion resistant coating on the substrate having the nano-particle-coated surface.
