1. A finger mountable sensor assembly comprising:
- (a) a finger mountable housing having a palmar aspect and including a finger receptacle, the finger receptacle having a dorsal aspect;
(b) an ultrasound transceiver located on said finger receptacle on said palmar aspect of said housing;
(c) a T shaped assembly comprising three branches of electrically conductive material, wherein said first branch and said second branch extend around said finger receptacle from said ultrasound transceiver to said dorsal aspect of said finger receptacle; and
(d) said third branch of electrically conductive material extends away from said dorsal aspect of said finger receptacle; and
(e) wherein said third branch of electrically conductive material is interconnected electrically with said sensor assembly transceiver by being interconnected electrically with said first and second branches in a location which is proximal to said dorsal aspect of said finger receptacle.

10. A finger mountable sensor assembly comprising:
-
(a) a finger mountable housing having a palmar aspect and a dorsal aspect and including a finger receptacle; (b) an ultrasound transceiver located on said palmar aspect of said housing comprising a piezoelectric material and an acoustically absorptive backing material; (c) two branches of electrically conductive material connected to said ultrasound transceiver, said branches extending around said finger receptacle within said housing to the dorsal aspect of said housing, thereby adapted to encircle a user'"'"'s finger located within said finger receptacle, wherein said two branches connected to said transceiver form a ring; (d) a third branch of electrically conductive material extending away from the dorsal aspect of said housing; and (e) wherein said third branch of electrically conductive material is interconnected electrically with said transceiver by being interconnected electrically with said two branches. - View Dependent Claims (11, 12, 13, 14, 15)
