Abstract: PROBLEM TO BE SOLVED: To provide a thin-film strain gauge capable of measuring only strain without large effect of pressure and temperature variations. SOLUTION: The following equations (1) and (2) are the fundamental equations used for providing the gauge: Ksl =(Kw .lA+Kl .lB)/(lA+lB) (1) Ksw =(Kl .lA+Kw .lB)/(lA+lB) (2) (Ksl : Longitudinal gauge factor of a sensor Ksw : Wide gauge factor of a sensor Kl : Longitudinal strain sensitivity of a material alloy Kw : Wide strain sensitivity of a material alloy lA: Wide length of a resistor film lB: Longitudinal length of a resistor film). The longitudinal and wide strain sensitivities, Kl and Kw respectively, of a material alloy are measured. The ratio of a wide length of a resistor film lA to a longitudinal length of a resistor film lB can be obtained using a relation lB=-Kl /Kw .lA which is derived from the equation (2) by assuming the wide strain sensitivity of a material alloy equal to zero: Kw =0.  The value of the longitudinal gauge factor of a sensor Ksl is obtained by substituting the ratio of a wide length of a resistor film lA to a longitudinal length of a resistor film lB into the equation (1). The shape characterizes that thin film strain gauge of a material alloy can be determined using the ratio of a wide length of a resistor film lA to a longitudinal length of a resistor film lB.

Title: Band edge amplitude reduction system and method
Inventor: DIMEO RICHARD W
IPC: H04B1/10
Filed: 2001-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a band edge power cancellation system that reduces interference in a wireless communication system consisting of adjacent cells. SOLUTION: The band edge amplitude reduction system changes a filtering characteristic of a receiver on the basis of a signal adjacent to an edge of the operating band of the receiver and/or the amplitude of a signal which is not under the power control of the receiver. For example, the receiver measures power level over a bandwidth at the band edge of the operating band of the receiver. When the power of a signal adjacent to the operating band is too strong for the signal power within the operating band, an overload protection circuit changes the filtering characteristics of the receiver, to enhance the attenuation of the signal from the adjacent band.  In certain embodiments, the overload protection circuit enables a filter, whose bandwidth is narrower, to switch the signal to attenuate the signal from the adjacent band at the edge of the operating band of the receiver, so as to prevent the interference with or the overload of the receiver by signals from the outside of the operating band and/or signals which are not under the control of the receiver.
