摘要： A diaphragm structure with a first substrate (10a) including a first surface (12a) with an annular groove therein and a second opposing surface with an annular groove (30a, 32a) on each side of annular groove in the first surface defining a first diaphragm. (18a) A second substrate (10b) also includes a first surface with an annular groove therein (14b) and a second opposing surface with an annular groove on each side of the annular groove in the first surface defining a second diaphragm. (18b) A diaphragm overload stop (40a) is located behind the first and second diaphragms.

摘要： A power line communications network carries power and communications signals over power lines. Fitted in the power line is a fuse unit (300) which has means for coupling communications signals to and/or from the power line. The fuse unit may include a high-pass filter. The fuse unit (300) is adapted to mate with an existing fuse socket in the power line to replace an existing fuse, thereby minimising disruption and simplifying installation. The fuse unit can also include means for impeding flow of non-power signals along the line.

摘要： A differential pressure sensing system is provided. The sensing system includes a membrane layer (38) having a channel extending diametrically therein, and including one or more cavities provided radially outbound of the channel and at least one resonant beam (66) disposed in the channel and configured to oscillate at a desired frequency. The system further includes sensing circuitry configured to detect oscillation of the at least one resonant beam indicative of deformation in the membrane layer.
摘要翻译：提供差压感测系统。感测系统包括膜层（38），其具有在其中径向延伸的通道，并且包括设置在通道的径向出射处的一个或多个空腔以及设置在通道中并被配置为以期望频率振荡的至少一个谐振梁（66）。该系统还包括感测电路，其被配置为检测指示膜层变形的至少一个谐振光束的振荡。
