Abstract: A building monitor for controlling an environment in a region of a building. The monitor is configured to couple to a building system and operable to change a state of a building system. The monitor comprises a processor and a receiver coupled to the processor. The receiver is configured to wirelessly detect the presence of one or more electronic device thereby to indicate an occupancy level of a region of a building. The processor is configured to receive an environmental signal indicative of an environmental condition in a region of a building. The monitor is configured to output a signal for controlling a state of a building system in dependence on the indicated occupancy level and/or the indicated environmental condition.

Abstract: A building system controller for controlling an environment in a region of a building. The controller is coupled to a building system and operable to change a state of the building system. The controller comprises a processor and a receiver coupled to the processor, the receiver being operable to incidentally observe a wireless signal from an electronic device in the region of the building. The processor is configured to determine whether the observed signal satisfies a predetermined control criterion, and the controller is configured to change a state of the building system in dependence on the determination that the control criterion is satisfied.

Abstract: A method of mapping a tissue characteristic in a tissue sample comprises gathering infrared absorption data from the sample at selected wavelengths, and determining, from the infrared absorption data, a first measure of the amount of power or energy absorbed attributable to an amide moiety and a second measure of the amount of power or energy absorbed attributable to a phosphate moiety. A ratio of the first measure and the second measure is used to establish a histological index. The histological index may be used to indicate a malignancy grade of tumour in the tissue.
