A method for monitoring the supply voltage of a hearing aid comprising an electric cell () comprises the steps of counting the number of times the supply voltage falls below a predetermined value, and setting an alarm flag if said number of times reaches a predetermined value. The method may be implemented using a circuit for monitoring the supply voltage of an electric cell. The circuit comprises a timer timing a detection interval, a detector for detecting drops in the voltage below a predetermined threshold value, a counter for counting the number of detections within said detecting interval, means () for setting an alarm flag if said number of times reaches a predetermined value within said first detection interval, and means () for suspending alarms during warm-up phase.

Battery alarm for a hearing aid, a hearing aid and a method for the use in a battery alarm

A hydraulic braking system, method for controlling the hydraulic braking system, and a control system for controlling the hydraulic braking system are provided. The hydraulic braking system may be applied to any kind of moving elements or systems. For example, this system can be used with wind turbines, conveyor systems, etc.
