Abstract: Aspects of the disclosure are directed to a spray gun apparatus having a casing with a nozzle. A rod extends within the casing and has an end portion with openings therein, for dispensing material. The rod operates with the casing to move relative to one another, for selectively dispensing the material. When the nozzle is positioned such that it is offset from the end portion of the rod, fluid material is allowed to flow out of the rod and is dispensed through the nozzle. When the end portion of the rod is positioned to seal the nozzle opening (e.g., via relative movement of the casing and rod), the fluid material is prevented from being dispensed through the nozzle. In certain implementations, an adapter interface is operable for coupling to an aerosol container having the material to be dispensed, and includes a conduit coupled to the rod for supplying the material.

Abstract: The system described herein relates to commissioning variable frequency drives of electric drive systems, where at least one variable frequency drive has wireless data transmission equipment via which the variable frequency drive is supplied with data during commissioning. A commissioning device connects with the wireless data transmission equipment of the variable frequency drive during commissioning to transmit data to the variable frequency drive. The wireless data transmission equipment of the variable frequency drive is set up before commissioning so that the variable frequency drive can be communicated with under an individual identifier specific to the respective variable frequency drive and during commissioning identification of the individual variable frequency drive is carried out by the commissioning device using the identifier.

Abstract: An single component light-curable orthodontic adhesive includes a curable resin monomer component; a quaternary curing initiator system; and filler. The orthodontic adhesive has a long working time (W) and short curing time (C). The adhesives are suitable as light-curing and may include a colorant. Suitable colorants include reversible, thermochromic dyes. The adhesive may also include a resin toughening component.

Abstract: An apparatus and system are provided for simultaneously analyzing a plurality of analytes anchored to microparticles. Microparticles each having a uniform population of a single kind of analyte attached are disposed as a substantially immobilized planar array inside of a flow chamber where steps of an analytical process are carried out by delivering a sequence of processing reagents to the microparticles by a fluidic system under microprocessor control. In response to such process steps, an optical signal is generated at the surface of each microparticle which is characteristic of the interaction between the analyte carried by the microparticle and the delivered processing reagent. The plurality of analytes are simultaneously analyzed by collecting and recording images of the optical signals generated by all the microparticles in the planar array.

Abstract: A dental apparatus for use with a connecting member coupled to a jaw in a patient's mouth. The apparatus includes an orthodontic device and a connecting device carried by the orthodontic device. The connecting device includes a receptacle adapted to partially receive the connecting member and a blocking member. The blocking member is moveable relative to the receptacle between an opened position in which the connecting member may be disengaged from the receptacle and a closed position in which the connecting member is captured within the receptacle for pivotally engaging the orthodontic device with the connecting member. The orthodontic device may further include a biasing member selectively activated to provide a spring-biased force to the jaw. A method of using the dental apparatus includes moving the blocking member to capture/release the connecting member in the receptacle and activating/deactivating the biasing member to operate the apparatus in a different mode.

Abstract: A disclosed method determines fluid pressure inside a vessel without compromising the integrity of the vessel. A sensor is positioned in operative communication with the external wall of the vessel such that expansion of the external wall of the vessel exerts a force against the sensor that is directed substantially radially outward with respect to the vessel. A substantially radially inward force is caused to be directed against the sensor in response to the substantially radially outward force exerted by the external vessel wall. The sensor can thus be used to detect the magnitude of the substantially radially outward force, which can be used to determine the pressure of the fluid within the vessel.

Abstract: A method for measuring pressure within a heart includes the steps of: (1) providing a passive wireless pressure sensor having a characteristic impedance and a deflectable surface, the characteristic impedance changing in response to deflection of the deflectable surface; (2) inserting the sensor to a location within the body of a patient at which the sensor can detect pressure within the heart; (3) affixing the sensor relative to the heart; (4) interrogating the sensor with an electromagnetic field; (5) receiving a signal from the sensor corresponding to a sensed pressure; and (6) leaving the sensor in situ so that future pressure measurements can be made.

Abstract: An orthodontic device treats malocclusions using a telescopic rod fixed to a molar on the upper arch and a molar on a lower arch. The telescopic rod lengthens and shortens during opening and closing of the jaw. The telescopic rod encourages the patient to properly position their jaw causing adaptation thereby treating the malocclusions.
