Abstract: A vibrator assembly (100) for a radio (200) having a transducer (110) includes a front housing (102) having first and second recessed cavities (104, 106) within which a vibrator (108) and transducer (110) are seated. A unitary molded pad (122) is configured to cover the vibrator (108) and a portion of the transducer (110). When a bezel (128) is attached to the front housing (102) of the radio, the unitary molded pad (122) is compressed against the vibrator (108) to provide increased rigidity of the vibrator within the first recessed cavity (104). The unitary molded pad (122) transfers vibrations emanating from vibrator (108) to the radio surface while providing a seal about the transducer (110).

Abstract: An apparatus for disassembling a head and acetabular component of a bipolar orthopedic hip prosthesis. The head includes a female taper configured for engaging a corresponding male taper of a femoral component of a hip prosthesis. The acetabular component includes a cavity in which the head is elastically constrained. The apparatus includes a rod having a male taper at one end thereof sized and configured to be received in taper locking engagement in the female taper of the head of the bipolar prosthesis. The rod has external threads that engage internal threads of a sleeve surrounding the rod. The sleeve includes a thrust surface at one end that engages the acetabular component as the sleeve is rotated relative to the rod. The sleeve causes the acetabular component to be pressed off of the head while the head remains taper locked to the rod. Continued rotation of the sleeve causes the head to be pressed off of the taper of the rod.
