A hair consultation tool arrangement is disclosed comprising a digital video camera () adapted for continuously taking pictures of a model's head and hair (), a processing unit () having a camera interface for collecting pictures recorded by the digital video camera (), a processor with an image processing software tool implemented for processing the collected pictures and a display interface for sending the processed pictures () to a display device (), and a display device () for presenting the processed pictures (). The hair consultation tool arrangement () comprises an illumination device () directed towards the model's head and hair () for illuminating the part of the model () imaged by the digital video camera ().

Hair consultation tool arrangement and method

The invention relates to a method for producing a time base for a microcontroller and a simple circuit arrangement therefor, which comprises an RC-element having a specific time constant, said element being connected to a connection of the microcontroller. According to said method, the capacitor of the RC element is charged to an initial voltage in a first step, then in a second step, the number of timed impulses is counted until the voltage on the capacitor falls below the initial voltage to a determined percentage of the initial voltage or a voltage threshold value, and then in a third step, the counted number of timed impulses is used as a time base.

Determining a time base for a microcontroller

A method for detecting the level of a liquid in a container. The method includes applying a predetermined voltage to a level measuring electrode, disposed within the container, for a predetermined first period of time; then, discontinuing the application of the voltage and waiting a predetermined second period of time; and then measuring an electrode voltage at the level measuring electrode.

Methods and apparatuses for detecting the level of a liquid in a container

Methods and devices for the conditioning of a rechargeable battery. The methods include providing a fully charged battery and discharging that battery to a voltage threshold value. The time required to discharge the rechargeable battery to the voltage threshold value is measured and then compared to a reference value. If the discharge time is less than the reference value, the battery is then further discharged. The methods can be applied to rechargeable batteries used in consumer products such as electric shaver and electric toothbrushes. The devices include a rechargeable battery, a second device that detects whether the device is connected to an external energy sources, and an electronic circuit. The electronic circuit discharges the battery by way of a load only if the device is connected to an external energy source. The devices can include appliances such as an electronic shaver or an electronic toothbrush.

Conditioning of a rechargeable battery

The invention is directed to a method for determining the status of a primary or secondary battery in which said battery is discharged to a specific residual charge. Following a replacement or full charge of the battery, the invention provides for a measurement of the time which elapses until the battery voltage has dropped to a first voltage threshold value. Then the first voltage threshold value is lowered by an amount dependent on the measured discharge time. It is only the dropping of the battery voltage to the lowered voltage threshold value which is taken as an indicator for the battery's discharge to the residual charge.
