Abstract:
A camera mode controlling method using a pressure detection sensor and a mobile communication terminal for performing the method are provided to turn off LCD(Liquid Crystal Display) backlight when a camera module is driven, and to enter a preview mode, then to maintain the off-state of the LCD backlight if a user does not press a camera button at more than certain strength in the preview mode, thereby reducing current consumption. Entrance of a camera mode is requested(S210). A mobile communication terminal enters the camera mode, and displays a preview screen which displays an image of an object(S220). The terminal senses strength of a camera button being pressed by using a pressure detection sensor, compares the sensed strength with the first and third preset threshold values, and controls so that different modes can be carried out according to the compared results(S230-S280).

Abstract:
A method of sensing a pressure applied to a surface comprises monitoring an electrical signal generated by redistribution of mobile ions in a piezoionic layer under the surface. An externally applied local pressure at a portion of the layer induces redistribution of mobile ions in the piezoionic layer. It is determined that the surface is pressured based on detection of the electrical signal. A piezoionic sensor includes a sensing surface; a piezoionic layer disposed under the sensing surface such that an externally applied local pressure on a portion of the sensing surface causes detectable redistribution of mobile ions in the piezoionic layer; and electrodes in contact with the layer, configured to monitor electrical signal generated by the redistribution of mobile ions in the piezoionic layer.
Abstract:
A low power consumption multi-contact micro electro-mechanical strain/displacement sensor and miniature autonomous self-contained systems for recording of stress and usage history with direct output suitable for fatigue and load spectrum analysis are provided. In aerospace applications the system can assist in prediction of fatigue of a component subject to mechanical stresses as well as in harmonizing maintenance and overhauls intervals. In alternative applications, i.e. civil structures, general machinery, marine and submarine vessels, etc., the system can autonomously record strain history, strain spectrum or maximum values of the strain over a prolonged period of time using an internal power supply or a power supply combined with an energy harvesting device. The sensor is based on MEMS technology and incorporates a micro array of flexible micro or nano-size cantilevers. The system can have extremely low power consumption while maintaining precision and temperature/humidify independence.
Abstract:
A deformation sensor package includes a housing having a base and a peripheral wall extending from the base. The base and peripheral wall define two cavities each configured to receive a potentiometer, such as a string potentiometer. The peripheral wall defines two apertures formed between a respective cavity and an exterior of the housing. Each aperture is configured to allow for the passage of a moveable sensing end of an associated potentiometer therethrough.

In one aspect, wireless strain gauges are described herein. In some embodiments, a wireless strain gauge comprises a radio frequency identification (RFID) tag and a nanocomposite backplane coupled to the RFID tag, wherein the resonant frequency of the RFID tag antenna demonstrates an exponential dependence or substantially exponential dependence on the strain sensed by the strain gauge.
Abstract:
A pressure testing device (10) for calculating a pressure in a flexible line (11) comprises a housing unit (14), a force sensor (70) mounted on the housing unit (14) and a clamp assembly having a clamp (60) mounted on the housing unit (14). The clamp (60) is operable to compress the flexible line (11) against the force sensor (70) by a predetermined degree of deformation of the flexible line (11). The device (10) includes a displacement sensor (90) adapted to measure a displacement of the clamp (60). The device (10) also includes a controller (120) having a processor in communication with the force sensor (70) and the displacement sensor (90), and a memory unit (122) containing stored data. At the predetermined degree of deformation of the flexible line (11), the processor compares a first signal from the force sensor (70) and a second signal from the displacement senor (90) with the stored data to estimate the pressure within the flexible line (11).
Abstract:
A surface mounted monitoring system is disclosed that is useful for detecting the presence of both ordinary and excessive loads on a surface, and for providing real-time or near real-time trending data. The system includes an array of force transducers disposed on the exterior surface of a structural member such as a roof. In an exemplary embodiment, transducers may be placed on an interior surface, such as embedded within insulation. The force transducers detect the magnitude of a load force acting on the surface. A data analysis module (DAM) may record force readings in a circular memory buffer, so that recent data can be recovered in the event of a catastrophic collapse. The DAM may also communicate with a monitoring device that can display real-time loading data to a user and perform other analysis.
