Abstract: Processing of merchant-specific functionality services during proximity connection transactions. The merchant terminal transmits additional data to the computing device that enables the device to identify the merchant. The computing device can enable merchant-specific features, such as offers, rewards, loyalty information, and other incentives that are applicable to the identified merchant. The bi-directional communication between the devices permits the computing device to transmit these identified incentives to the merchant terminal. The merchant terminal can then adjust the purchase price. The computing device can also enable a merchant-specific financial instrument and can communicate the identity of the merchant to a management system.

The dental brace is simple in construction and easy to assemble, hereby raising production efficiency and yield.

Abstract: When a transverse force is applied to a stretched string that is fixed by its two ends, the string bends and the strain of the string increases to balance the transverse force. As a result, the axial force along the string can increase much more than the transverse force applied. By developing Fiber Bragg Grating (FBG) accelerometer based on transverse force rather than axial force, the force required for maintaining a high sensitivity is much smaller and thus the size of FBG accelerometers can be dramatically reduced. More importantly, FBG accelerometers based on transverse force have an inherent low cross-axial sensitivity. Simultaneous measurement of acceleration, temperature and displacement is realized by using two under-tensioned FBG. Displacement change is calculated by using the differential of the two FBG results.
