    Abstract: Embodiments are directed to a strain sensor having a thermally conductive element and methods related to the use thereto. In one aspect, an embodiment includes a substrate. A first strain-sensitive element may be positioned on a first surface of the substrate and a second strain-sensitive element may be positioned on a second surface of the substrate. The embodiment may further include a thermally conductive post positioned within the substrate and extending beyond at least one of the first or second surfaces. The embodiment may further include a thermally conductive plate separated from the substrate and attached to the thermally conductive post.

    Abstract: In a system for detecting merchandise theft, pre-loaded force sensitive input devices, force sensing resistors (FSR), are formed as a multiple membrane assembly that is capable of detecting low intensity pressure inputs and quantifying varying applications of pressure to the sensor surface. Pre-loading the force sensor elements results in controlled amount of force between the two substrates causing a constant state of pre-load and eliminating the low-end or minimal pressure signal noise associated with unloaded sensors. Pre-loading the force sensing resistor sensors also enables the sensor to detect removal of low intensity pressure input such as might occur during theft of light weight articles placed in contact with the pre-loaded force sensor. Using an FSR or FSR Matrix Array will enable any handling of protected retail packaging to be detected and identified. A library of “touches” can be established that will yield cutting, ripping, twisting, etc. making the detection of a theft in progress more accurate.

    Abstract: A pressure measurement device includes a platen, a pressure sensor, a signal acquisition section, and a data processing section. The pressure sensor includes a plurality of pressure-sensitive points arranged on the platen. The signal acquisition section is configured to acquire measurement data that is obtained when a measurement object in contact with a surface of the platen passes over the pressure sensor a plurality of times. The measurement object moves relative to the platen and along a circular orbit on the platen. The data processing section is configured to calculate periods in each of which the measurement object passes over the pressure sensor and to acquire period data for each of the periods from the measurement data.
