A variable illuminator, for instance a device for scanning a beam of light, emits a selected amount of power to a plurality of spots across a field of view. The amount of power is determined as inversely proportional to the apparent brightness of each spot. In the case where the spot size is equal to pixel size, the device may operate with a non-imaging detector. In the case where pixel size substantially equals spot size, the output of the variable illuminator may be converged to produce a substantially uniform detector response and the image information is determined as the inverse of a frame buffer used to drive the variable illuminator. The illuminator and detector may be driven synchronously. In the case where an imaging detector is used, the variable illumination may be used to compress the dynamic range of the field of view to substantially within the dynamic range of the imaging detector.

A method for influencing the load on a driver while driving a motor vehicle, in which a workload is determined from physiological driver data detected by sensors, and to an apparatus for carrying out the method. The load or the workload on the driver is kept in an optimum workload range and brought back to this optimum range if there is any discrepancy, thus ensuring an optimum driver performance level and attention level. For this purpose, vehicle systems are driven as a function of the detected workload value in such a way that the driver is influenced via his visual, auditory or tactile sense channels in such a way that his workload value returns to a value in the optimum workload range.

A method is provided for processing a neural measurement obtained in the presence of noise, in order to detect whether a locally evoked neural response is present in the neural measurement. A first neural measurement is obtained from a first sense electrode. A second neural measurement is contemporaneously obtained from a second sense electrode spaced apart from the first electrode along a neural pathway of the neural response. A neural response decay is determined, being a measure of the decay in the neural response from the first sense electrode to the second sense electrode. A ratio of the neural response decay to an amplitude normalising term is calculated. From the ratio it is determined whether a locally evoked neural response is present in the neural measurement.

Apparatus and method for tracing a geographical journey taken by an entity, for example an article (shipment), asset or person, on a worldwide map uses a miniature, passive, low power, radio receiver tag that is attached to the entity and collects multiple FM spectra during the travels of the entity. When the tag is retrieved at the end of the journey, the FM spectra are downloaded and compared against a collection of constructed spectra constructed from antenna transmission and location data derived. Correlating each of the spectra collected by the receiver tag with the corresponding spectra in the database allows the regions traversed by the receiver tag, and hence the entity, during its travels to be plotted.

A scanner performs an initial low resolution scan of an area including an image and, after analyzing the initial scan data to determine the type of the image, a computer sends commands to the scanner to direct the scanner to perform a second scan. The second scan can be limited to the precise area of the image, and can be customized to perform efficient scanning based in the image type (e.g., color vs. black and white, or photo vs. text).

An audio device is arranged to present a plurality of test audio signals to a user where each test audio signal comprises a signal component and a noise component. A user preference processor (109) receives user preference feedback for the test audio signals and generates a personalization parameter for the user in response to the user preference feedback and a noise parameter for the noise component of at least one of the test audio signals. An audio processor (113) then processes an audio signal in response to the personalization parameter and the resulting signal is presented to the user. The invention may allow improved characterization of a user thereby resulting in improved adaptation of the processing and thus an improved personalization of the presented signal. The invention may e.g. be beneficial for hearing aids for hearing impaired users.
