Abstract: A buffer for holding a pipe adapted to transport a fluid includes a base. The buffer further includes a plurality of fingers extending outwardly from a first side of the base, wherein a first finger of the plurality of fingers and a second finger of the plurality of fingers define a cavity for receiving the pipe, the first finger extends outwardly from a first end of the base, and the second finger extends outwardly from a central portion of the base, and a third finger of plurality of fingers extends outwardly from a second end of the base opposite the first end, wherein the second finger is between the first finger and the third finger. The buffer further includes at least one roller on a second side of the base opposite the first side.

Abstract: A method of monitoring wear of a buffer includes holding a pipe for transporting a fluid and an electrical cable using a buffer placed on a support plate. The buffer includes a base, a plurality of fingers, and a roller contacting the support plate. The plurality of fingers includes a first finger, a second finger, and a third finger. The first finger and the second finger define a first cavity for receiving the pipe, and the second finger and the third finger defines a second cavity for receiving the electrical cable. The method includes detecting acoustic waves generated by the roller on the support plate. The method further includes analyzing changes in frequencies of the acoustic waves to determine an extent of the wear of the roller over time. The method includes triggering an alert when an increase in the frequencies of the acoustic waves exceeds a pre-determined threshold value.

Abstract: A sensing apparatus utilizing film bulk acoustic resonators (FBARs). The film bulk acoustic resonator has a bulk acoustic wave velocity (Vb) and a corresponding resonant frequency (f). When the FBAR is subjected to a force such as acceleration, g-force or an air pressure, the bulk acoustic wave velocity changes to obtain a frequency downshift (?f) in response to deformation caused by the force. A magnitude of the force is then obtained by calculating the frequency downshift (?f).

Abstract: A filter assembly capable of unbalanced to balanced conversion. An unbalanced to balanced conversion unit is coupled to an input terminal for transforming a received unbalanced signal thereat to a balanced signal and a lattice filter coupled between the unbalanced to balanced conversion unit and two output terminals for eliminating or rejecting the noise of the balanced signal.
