Abstract:
A flashlight comprising a high-pressure mercury vapor discharge lamp (1) (UHP lamp) is described. The miniaturized UHP lamp (1) enables flashlights with improved range due to the small electrode distance at high intensity in comparison to conventional HID lamps (mostly used in automotive lighting applications) as proposed by prior art. Additionally the application range is enlarged due to the smaller size of the high-end flashlight and the reduced requirements with respect to the driver circuitry.
Abstract:
A low-pressure gas discharge lamp provided with a gas discharge vesseL (1) containing a gas filling with a metal chelate complex (ML2) of a central metal ion and at least one bivalent or multivalent ligand and with a buffer gas, with internal or external electrodes (2), and with means for generating and maintaining a low-pressure gas discharge.
Abstract:
The invention relates to a device (1) for the topical delivery of nitric oxide to a skin surface, the device comprising a piezoelectric transformer (13) as a means for generating the nitric oxide. The device according to the invention is suitable for use by a patientin a home environment.
Abstract:
A flashlight comprising a mercury vapour discharge lamp (12) as e.g. a HID Lamp (High Intensity Discharge Lamp) with adjustable light output is described. The extreme brightness and peak intensity of mercury vapour discharge lamps (12) is enabled for signalling in mobile lighting applications without reducing the lifetime of the 5 mercury vapour discharge lamps (12).
Abstract:
A sensor system is described, using self-mixing laser sensors (10) and an analyzer circuit (30) in order to determine the velocity of a vehicle, such as a car, and the rotational velocity of a wheel (20) of the car. Deviations between the velocity of the vehicle and the rotational velocity of the wheel (20) can be used to determine sliding of the wheel (20) and, finally, the traction or, more specifically, the coefficient of driving friction between the wheel (20) and the surface the car is driving on. Furthermore, a vehicle control system is described, initiating test accelerations of a wheel (20) by means of a control circuit (50) and control means (300, 400) in order to determine the coefficient of driving friction during driving. The test accelerations initiate short periods of sliding of the wheel (20) and the sliding is detected by means of the sensor system.
