Abstract: A device for controlling battery operation includes a battery cell, a thermal cutoff, and a battery management system. The thermal cutoff is coupled in series between the battery cell and a system load of the device. The thermal cutoff has at least three terminals. A first terminal of the thermal cutoff is electrically-coupled to the battery cell and a second terminal of the thermal cutoff is electrically-coupled to the system load. The thermal cutoff includes a permanent failure mechanism having an open state and closed state wherein the closed state allows electrical communication between the first terminal and the second terminal. The battery management system is electrically-coupled to a third terminal of the thermal cutoff. The permanent failure mechanism permanently switches to the open state in response to an electrical signal from the battery management system.

Abstract: A flange for a medical collecting bag having an aperture allowing bodily fluids or exudates to enter the bag. The flange has an inner rim delimiting the aperture therein, and a central area encircling the aperture, which area has a predetermined weakening line pattern. The force needed for removing the bag flange from the skin or a body side member is smaller than the force needed for breaking the weakening lines which enables a simple gradual enlargement of the aperture of an ostomy device for adaptation of the aperture to the size of the stoma or for adaptation of the aperture to the size of a wound, as well as a complete removal of the bag flange when substituting the bag.

Abstract: A resettable thermal switch utilizing the principle that the permeability of a ferromagnetic material is sensitive to temperature variations in the vicinity of the Curie temperature. The resettable ferromagnetic thermal switch includes a resilient arm having a ferromagnetic aspect associated therewith (inherently or by attachment), an electrical contact including a stationary contact component and a movable contact component located at a distal location of the resilient arm, and a magnet located on one side of the resilient arm. The resilient arm has a predetermined inherent spring force urging the movable contact component toward or away from the stationary contact component depending on whether the electrical contact is to be spring biased closed or spring biased open, respectively. The magnet is located to provide a magnetic attraction force with the temperature dependent permeability of the ferromagnetic aspect in opposition to the inherent spring force.

Abstract: Methods and apparatuses for magnetically detecting a temperature change for thermostat control thereof are disclosed. A thermostat control device can be configured to include at least one bi-metallic strip that is configured to experience a change in angular position in response to a temperature change. The thermostat control device is generally associated with a Hall sensor, which includes a plurality of magnets that can experience movement relative to the Hall sensor in response to the change in the angular position of the bi-metallic strip. The temperature change can then be automatically and/or electrically detected in response to the movement of the magnets, wherein the temperature change is utilized for thermostat control thereof.

Abstract: A control device including a switch with a ferromagnetic armature moving between a first position and a second position. The armature actuates a plunger that causes the switch to snap from an open position to a closed position. An energy-storing member may be positioned adjacent the ferromagnetic armature, the energy-storing member moving a magnet between an attracting position and a non-attracting position based on a temperature of an environment surrounding the energy-storing member. When the energy-storing member positions the magnet in the attracting position, the magnet causes the armature to snap from the first position to the second position, thereby actuating the plunger and causing the switch to snap from the open position to the closed position. A ferromagnetic backstop may also be positioned adjacent the magnet and coupled to the energy-storing member to hold the magnet and the energy-storing member in the non-attracting position.

Abstract: A switch has a housing which receives a temperature-dependent switching mechanism and comprises a lower part on whose inner bottom a first countercontact for the switching mechanism is arranged, and a cover part, closing off the lower part, on whose inner side a second countercontact for the switching mechanism is provided. The switching mechanism has an electrically conductive spring disk which carries a movable contact element and operates against a bimetallic snap disk which sits approximately centeredly on the movable contact element, the spring disk being braced at its rim against the countercontacts and pressing the movable contact element against the countercontact when the switching mechanism is below its response temperature. The countercontact against which the spring disk is braced at its rim below the response temperature is magnetic.

A member made of magnetic material is disposed in the vicinity of the bimetal plate. The fixed member for loosely holding the bimetal plate may be made of magnetic material. The fixed metal fitting for connecting a first fixed plate with a movable plate is extended near to the bimetal plate and is made of magnetic material.

Abstract: A temperature switch includes a housing, a fixed contact positioned in the housing, a movable contact member mounted in the housing carrying a movable contact and urged to first and second positions where the movable contact is in abutment with or displacement from the fixed contact, respectively, a permanent magnet mounted in the housing, a thermally sensitive member mounted in the housing so as to be exposed to a region the temperature of which is to be determined wherein the thermally sensitive member includes a magnetically soft, amorphous metal member and is magnetically coupled to the permanent magnet, and an operating member which includes magnetic material wherein a first end thereof engages the movable contact member and a second end thereof opposite the first end is attracted to the thermally sensitive member against the resilience of the movable contact member, thereby causing displacement of the movable contact to the second position and wherein the thermally sensitive member includes a paramagnet

Abstract: The disclosure relates to an over-temperature limit switch for automatically making or breaking an electrical circuit at a predetermined temperature. The actuating force for the switch is provided by a temperature dependent bimetallic spring and the latching function of the switch is provided by a pair of magnets. One of the magnets, a permanent magnet, is secured to the bimetallic spring and the other magnet, a non-permanent or "soft" magnet, is disposed in the base of the switch opposite the permanent magnet. The non-permanent magnet has a transition temperature associated therewith indicating the temperature above which the permeability of the magnet diminishes to such an extent that it can no longer carry sufficient magnetic lines of flux from the permanent magnet to hold it against the force of the bimetallic spring. The bimetallic spring is adapted to exert a bias force tending to open the switch at a temperature below the transition temperature of the non-permanent magnet.

Abstract: The disclosure relates to a system and method whereby bimetallic discs as well as a completed thermostat can be dynamically tested non-destructively. The bimetallic disc can be tested by utilizing its magnetic properties, the magnetic properties of the disc being sensed by a magnetic transducer under operating conditions to provide a velocity curve of disc movement. The thermostat is tested in the same manner as the disc with simultaneous monitoring of the electrical switch controlled by the disc to insure operation thereof at the ideal point on the disc velocity curve.
