| 20110051141 | METHODS AND DEVICES FOR MONITORING OF FRYING OIL QUALITY - Herein are disclosed methods and devices for evaluating the quality of oils (e.g., cooking oil or flying oil). The methods can provide an indication of the free fatty acid content of the oil. The methods use an optical interrogation device to provide an indication of free fatty acid based on quantitative measurements of optical reflectance from test zones on a sampling substrate. | 03-03-2011 |

| 20090295539 | HAND HYGIENE DELIVERY SYSTEM - Hand hygiene apparatuses and methods for monitoring hand hygiene and for dispensing hand soap or hand sanitizers. An illustrative hand hygiene apparatus includes a computer, a database stored on the computer, a biometric sensor operatively coupled to the computer, a hand hygiene dispenser operatively coupled to the computer, and a hand soap or hand sanitizer disposed adjacent to the hand hygiene dispenser. The database might include a collection of partial biometric data for a group of persons. An illustrative method may include collecting a set of partial biometric data, providing a biometric sensing apparatus and a hand hygiene dispenser coupled to the biometric sensing apparatus, sensing biometric data from a first individual from the group of persons with the biometric sensing apparatus, identifying the first individual by comparing the sensed biometric data with the set of partial biometric data, and dispensing a hand soap or hand sanitizer from the hand hygiene dispenser onto the hands of the first individual. | 12-03-2009 |

| 20110059532 | MONITORING OF FRYING OIL QUALITY USING COMBINED OPTICAL INTERROGATION METHODS AND DEVICES - Herein are disclosed methods and devices for optically monitoring multiple parameters of an oil sample. In one embodiment, the methods and devices can be used for determining the quality of cooking or flying oil in terms of the free fatty acid content and total polar compound content of the oil. The methods use an optical absorbtive/reflective property in evaluating the free fatty acid content, and use optical fluorescence in evaluating the total polar compound content, with both measurements using a single sampling substrate and a single measuring device. | 03-10-2011 |

| 20110035427 | PIXEL SENSOR CONVERTERS AND ASSOCIATED APPARATUS AND METHODS - There is described a pixel sensor converter for an image sensor array. In particular, a pixel sensor converter comprising: a delta-sigma converter comprising a modulator and a decimator. In some examples, the modulator is configured to be in communication with a detector, such as a photo-detector, and is configured to sample an analogue signal received from a detector at a particular sampling rate. The modulator is further configured to provide a bit stream of a particular bit rate. The provided bit stream corresponds to a sampled analogue signal. The decimator is in communication with the modulator, and is configured to receive and modify a bit stream provided from the modulator in order to provide a digital output signal. The provided digital output signal is representative of an analogue signal received at the modulator, but having a reduced bit rate than a corresponding bit stream provided by the modulator. | 02-10-2011 |
