Abstract:
There is provided a method and device for measuring an ion concentration of a sample. The method comprises exposing a chemical sensor to the sample to provide an electrical output signal 5 representing said ion concentration and controlling a titrator exposed to the sample to release or absorb a quantity of ions to the sample. The method may use feedback means comprising Pulse Width Modulation control to drive the titrator such that the sample maintains a stable ion concentration.
Abstract:
An apparatus comprises a transducer having a first output signal and arranged to receive an electrical input. The transducer switches the first output signal between an ON and OFF state. The apparatus comprises a chemical sensing surface coupled to the transducer arranged to receive a chemical input.A signal generator oscillates one or more of said inputs to vary the switching point of the transducer. The oscillating input may be the chemical input and/or the electrical input. The output signal may be a pulse whose period ON or OFF is determined by the oscillating input modulated by the chemical input.

The system (110) furthermore comprises a controller (17) for selectively driving measurement and/or treatment means located at the target location based on the feedback signal from the pressure sensors (23). The present invention also provides a method for making a system (110) for controlling measurement and/or treatment means of a probe (10) and a method for controlling measurement and/or treatment means of a probe (10).
Abstract:
The present invention provides a location indicating device (10) for determining on skin of a human or animal body a location for performing measurement of a physiological parameter in and/or treatment of the human or animal body. The location indicating device (10) comprises a matrix (7) of electrodes for determining skin resistance at different locations on skin of a human or animal body and a calculating unit (8) for calculating a location with highest skin resistance. The location indicating device (10) furthermore comprises visualisation means (9) for indicating the location of highest skin resistance to a user. The present invention also provides a method for making such a location indicating device (10) and a method for determining on skin of a human or animal body a location for performing measurement of a physiological parameter in and/or treatment of the human or animal body by using such a location indicating device (10).

Abstract:
A hybrid vehicle has a power system (102) with a torsional coupling (206). The power system (102) includes a battery system (110) for receiving, storing and providing electrical power, an internal combustion engine (104) configured to provide rotational power through a flywheel (1804), a first motor-generator (106), a second motor-generator (108), a control system (202), and a torsional coupling (206). The torsional coupling (206) may absorb rotational shock caused by angular or rotational speed differences between the engine (104) and the first motor-generator (106). The torsional coupling (206) includes a driven plate assembly (1806), a cover assembly (1808) and an interconnecting plate assembly (1810). The interconnecting plate assembly (1810) may include a plurality of shock absorbing elements (1910) that absorb shock and vibration between the engine (104) and the motor-generator (106; 108).
