  • Patent number: 10291015
    Abstract: Electrical apparatuses with connector overheating protection and methods for protecting electrical apparatuses from connector overheating during current sinking and current sourcing operations are presented. The electrical apparatus includes an electrical connector and a temperature sensor, which is in direct contact with a physical part of the electrical connector. The temperature sensor monitors a temperature of the electrical connector during current sinking and current sourcing operations. During current sinking, if the temperature sensor senses a predetermined level of overheating of the electrical connector, then the sourcing of current to the electrical apparatus is switched off. During current sourcing, if the temperature sensor senses a predetermined level of overheating of the electrical connector, then the sourcing of current to the sinking device is switched off.

  • Patent number: 10236679
    Abstract: With an IC including a driver that drives a large current, its characteristics may be deteriorated or the IC may be broken by heat generated by the large current. By providing a plurality of sensors and disposing some of the sensors so as to be close to an output driver that flows a large current, which is a source of heat generation, an increase in the temperature of the IC can be rapidly detected, and the deterioration of the characteristics of the IC can be prevented by accurately actuating an overheating protection function based on a result of detection. Alternatively, breakage of the IC can be prevented by suppressing overheating.

  • Patent number: 10218169
    Abstract: When a temperature is less than a first threshold, a protection circuit unit executes a normal operation by a pulse width modulation. When the temperature is greater than or equal to the first threshold and is less than a second threshold, the protection circuit unit executes a first heat dissipation suppressing operation that suppresses a self-heating of a switching element. When the temperature is greater than or equal to the second threshold, the protection circuit unit executes a full off operation that terminates the switching element. When the temperature is decreased to be less than the first threshold and to be greater than or equal to a third threshold after the temperature becomes greater than or equal to the second threshold, the protection circuit unit executes a second heat dissipation suppressing operation that suppresses a heat dissipated due to an energization of the switching element.

  • Patent number: 10188458
    Abstract: The invention relates to an inductive disturbance reduction device (18) for reducing an inductive disturbance of a signal like an ultrasound signal to be transmitted via first connection conductors (25, 26) of an electrical connector (11), which is caused when ablation current flows through a second connection conductor (24) of the electrical connector. The inductive disturbance reduction device is adapted to induce a voltage, which at least partly compensates a voltage induced in the electrical connector, in order to reduce the inductive disturbance in the signals to be transmitted via the first connection conductors of the electrical connector. Since the inductive disturbance is reduced, a high quality electrical connection can be provided, without necessarily using, for instance, a technically relatively complex and expensive coaxial connector. The inductive disturbance reduction device may be integrated, for instance, in a part of the electrical connector or in a cable.
