A method of operating a milk frothing device that includes at least one processor operatively associated with one or more actuators. The method is performed by the at least one processor and includes calculating a number of the actuators activated by way of contact with an underside of a vessel, determining a presence or an orientation of the vessel based on the calculated number of the activated actuators, and controlling an operation mode of the milk frothing device based on the determined presence or orientation of the vessel.

A protective tube for sealed introduction into a process vessel at a process vessel port, the protective tube comprising a sealing base element which is connected onto the process vessel port and an elongate body with a bore. The elongate body comprises a closed distal end and an open proximal end, which is sealingly connected onto the sealing base element. The protective tube also comprises a receiving part, which is connected or attached onto the elongate body inside the process vessel so as to receive and hold a secondary temperature sensor from inside the process vessel. In addition, a reference temperature sensor is insertable into the bore from outside the process vessel. Also provided is a temperature measurement arrangement and a method for a temperature measurement in a process vessel.

A semiconductor package includes a first set of leads, a temperature sensor proximate the first set of leads, a second set of leads, a semiconductor die, a first electrical connection between the temperature sensor and the semiconductor die, a second electrical connection between the semiconductor die and the second set of leads, and mold compound at least partially covering the temperature sensor, the semiconductor die, the first set of leads and the second set of leads. The mold compound physically separates the semiconductor die from the temperature sensor and the first set of leads.
