Other aspects are described and claimed.

Described in detail herein is a system for the detection and notification of abnormal pallet temperature fluctuation. An exemplary system includes a pallet, an ambient air temperature sensor, an item temperature sensor, an indicator light, and an electronic device. The electronic device receives temperature readings from both the ambient air temperature sensor and the item temperature sensor and compares the temperature readings against a known set of temperature thresholds corresponding to the items on the pallet. Following a determination of an unacceptable variation from a threshold, the electronic device may provide a notification through the indicator light. The notification may correspond to the criticality of the threshold passed.

An information processing system includes an irradiation unit configured to irradiate a deposited material with electromagnetic waves, a detection unit configured to detect scattered waves or transmitted waves of the electromagnetic waves with which the deposited material has been irradiated by the irradiation unit, and a determination unit configured to determine a state of the deposited material from an image based on the scattered waves or the transmitted waves detected by the detection unit.

A method of improving the measurement accuracy of a digital ice rate sensor by providing an enhanced surface finish on a magnetostrictive oscillator detector probe by measuring the surface roughness of the detector probe, comparing the measured value to a critical value, and authorizing the probe for use in the digital ice rate sensor if surface roughness is within the critical value. Surface roughness may be measured optically or with a surface profilometer. Remedial steps taken if surface roughness is not within the critical value include reworking the probe surface finish and investigating the manufacturing process.

The present invention relates to a freeze detector (10) for a pipe or container (20) being adapted for holding and transporting water or water containing liquids, said freeze detector (1) comprising a microphone housing (13), comprising a microphone (11), adapted to be mounted on an outside surface (22) of said pipe or container (20), and adapted to receive sound from within said pipe or container (20), said sound forming an acoustic pattern, an attachment member (15) for attaching said microphone (11) to said pipe, and an processing unit(16) adapted to receive, process and analyze the acoustic pattern of the sound transmitted by the microphone and to be activated when at least one predetermined threshold value (T.sub.freeze) is detected in the acoustic pattern received by said microphone (11), wherein said threshold value (T.sub.freeze) indicates local freezing of said water or water containing liquids inside said pipe or container (20).

The present disclosure concerns the detection of ice within a system. More specifically, but not exclusively, the disclosure concerns the detection of ice accretion within a gas turbine engine. The apparatus and method relies on heating a first region (38) of a component (44) and comparing the measured temperature of the first region (38) with a second temperature value, possibly measured at a distinct second region (40) of the component (44).

An electronic device can output a priming cue prior to outputting an alert on the electronic device. A priming cue can be a haptic priming cue, a visual priming cue, an audio priming cue, or various combinations of these priming cues. The priming cue can be perceived by a user either consciously or subconsciously and can increase a user's perceptual state for the alert.

A sensor for detecting the level of accumulation of a material along an axis in a fluid environment, the sensor comprising (a) an optically transparent body having a third refractive index and an exposed surface defining a length extending at least partially in the direction of the axis; (b) at least one light delivery source for delivering light to the body such that the light is distributed along the length of the exposed surface; and at least one light receiver for receiving reflected light from the length of the exposed surface, wherein the amount of the reflected light depends on the level of the material accumulated along the length of the exposed surface.

A method for detecting a diaphragm of an electroacoustic sensor covered with snow/ice (e.g., an ultrasonic sensor on a vehicle). The method includes: a) after a sensor operation start, a temperature sensor, disposed in the interior of a sensor housing, ascertains a temporal temperature characteristic of an interior of the electroacoustic sensor, where the temperature of the sensor interior at the beginning of the sensor operation is below 0 C. In b), a second time range of the ascertained temperature characteristic is detected by a processing unit in that the temperature increase drops significantly in comparison with a temporally preceding first range. In c), if such a time range is detected, then it is inferred therefrom that the diaphragm of the electroacoustic sensor is covered with snow/ice. In d), if it was detected that a diaphragm of the electroacoustic sensor is covered with snow/ice, a warning is output to the driver.
