摘要： An ultrasonic bone testing apparatus has a foot well assembly and a shin guide assembly which are mechanically coupled to secure a foot and lower leg of patient. The shin guide assembly includes a molded form lined with contoured foam lining. An instep support guide having sliding blocks is mounted on the molded form. The sliding blocks attach the shin guide assembly to the foot well assembly. The apparatus further includes a transducer drive mechanism for positioning a pair of transducer assemblies. A controller automatically modifies the positioning of the transducer assemblies until ultrasonic coupling is achieved and a receiving transducer receives a signal of a predetermined quality. The distance between the transducers is continuously measured by a position encoder. The controller uses temperature readings from a temperature sensor to improve the accuracy of the position encoder measurements and correct for temperature dependent inaccuracy in the ultrasound measurement. A coupling pad and acoustical delay line of the transducer assembly provide a waveguide function to collimate an acoustical beam. The elastomer coupling pad has an angled surface which expels air bubbles from a contact area when pressure is applied to the pad.

摘要： An ultrasonic bone testing apparatus has a foot well assembly and a shin guide assembly which are mechanically coupled to secure a foot and lower leg of patient during the measurement process. The shin guide assembly includes a molded form which has a shin restraint section, an instep guide section and a foot restraint section. An instep support guide having sliding blocks is mounted on the molded form. The sliding blocks are inserted into respective channels of respective bridge brackets of the foot well assembly to attach the shin guide assembly to the foot well assembly. The apparatus further includes a transducer drive mechanism for positioning a pair of transducer assemblies. A controller automatically modifies the positioning of the transducer assemblies until ultrasonic coupling is achieved and a receiving transducer receives a signal of a predetermined quality. A coupling pad and acoustical delay line of the transducer assembly provide a waveguide function to collimate an acoustical beam a sufficient distance along a propagation axis to allow wavefronts to evolve onto a more uniform intensity pattern. The elastomer coupling pad has an angled surface which expels air bubbles from a contact area when pressure is applied to the pad.

摘要： A recessed fixture cover device comprising a plurality of components that may be economically and efficiently packed in an unassembled state for transport and/or shipping and then easily assembled to provide a thermal barrier, a fire barrier, an air barrier, a moisture barrier, and/or an insect intrusion barrier between the recessed fixture and the space immediately above and external to the installed cover device. An embodiment of a cover device may comprise two components that may be assembled to form a right-angled parallelepiped shape that lacks a bottom wall thereby allowing the cover device to be lowered onto and enclose a recessed fixture. One or more complimentary connections between abutting edges of the two components allow the two components to be either quickly assembled for use or disassembled for transport or storage thereby providing a benefit to both construction professionals and do-it-yourself property owners.
