Abstract
A tilt sensor with zero position indication for indicating a predetermined zero position, including an indication device with an optical indication means and a control unit for actuating the indication device, wherein the indication device is configured to transmit a set first signal from an optical indication means in the zero position and to transmit a set second signal from the optical indication means in a position deviating from the zero position, wherein the second signal comprises an item of information about an extent of the deviation of the position deviating from the zero position, and wherein the optical indication means consists of only one light source.
Claims14
A tilt sensor with zero position indication for indicating a predetermined zero position, comprising:
- an indication device with an optical indication means configured to emit light to a user's eye;
- and
- a control unit for actuating the indication device, wherein:
- the indication device is configured to transmit a set first signal from the optical indication means to the user's eye in the predetermined zero position and to transmit a set second signal from the optical indication means to the user's eye in a position deviating from the predetermined zero position,
- the second signal comprises an item of information about an extent of a deviation of the position deviating from the predetermined zero position,
- the second signal is formed as a continuous function of an amount of the deviation, the second signal being continuously changeable within a continuous range depending on the amount of the deviation, and
- the optical indication means consists of only one light source.
A method for indicating a predetermined zero position, comprising:
- detecting a current position relative to the predetermined zero position;
- generating a control signal;
- and
- actuating an indication device with an optical indication means such that light is emitted to a user's eye, the indication device being actuated on the basis of the control signal such that a set first signal is transmitted to the user's eye in the predetermined zero position and a set second signal is transmitted to the user's eye in the current position deviating from the predetermined zero position, wherein the second signal comprises an item of information about an extent of a deviation of the current position, wherein the second signal is formed as a continuous function of an amount of the deviation, the second signal being configured to change within a continuous range depending on the amount of the deviation, and wherein the optical indication means consists of only one light source.
A tilt sensor, comprising:
- an indication device consisting of one light source;
- and
- a control unit configured to actuate the indication device,
- wherein the indication device is configured to emit light from the one light source to a user such that the light emitted is visible to the user,
- wherein the indication device is configured to emit a first light signal to the user when the tilt sensor is in a zero position,
- wherein the indication device is configured to emit a second light signal to the user when the tilt sensor is in a current position, the current position being deviated from the zero position,
- wherein the first and second light signals are a flashing frequency, a colour, a variable duty cycle, and/or a brightness impression of an optical indication means,
- wherein the second light signal is indicative of an amount of a deviation of the second position from the first position and is formed as a continuous function of the amount of the deviation,
- wherein the control unit is configured to determine an amount of the deviation, and
- wherein the indication device is configured to emit a plurality of different light signals as the second light signal, each of the plurality of different light signals being indicative of the amount of the deviation of a given position from the zero position within a continuous range of positions.
