摘要： Pressure and mechanical sensors include a sensing component formed of a titanium and tantalum alloy having an elastic (Young's) modulus of less than about 80 GPa and a tensile strength of greater than about 1,000 MPa. The high strength and low elastic modulus, together with very low temperature dependence of the elastic modulus and very low linear thermal expansion, result in high resolution and precise measurement over a large temperature range.

摘要： A sensor preferably capable of high resolution sensing over a large operating range includes a composite diaphragm containing nanotubes or nanowires. The nanotubes or nanowires preferably form a mat that is embedded in insulating material, such as high dielectric or insulating thin films. The nanotubes or nanowires may provide the diaphragm with a Young's modulus of greater than about 1000 GPa and a tensile strength of greater than about 100 GPa. The strain in the nanotubes or nanowires may be measured by a change in resistance, voltage, current or capacitance.

摘要： A field device includes a power control module, a network interface module that communicates over a wireless network, and a device interface module for operating transducers, such as a sensor or an actuator. The power control module controls distribution of electrical power so that the network interface module receives electrical power while it is attempting to join the wireless network. Once the network interface module has joined the wireless network, the power control module allows the network interface module and the device interface module to share electrical power.
