    Abstract: An electronic device can include a first and second portions that are pivotally coupled to each other so that the electronic device can have at least a closed configuration and an open configuration. A magnetic sensor system can be carried by the electronic device to detect the closed configuration so that the electronic device can automatically turn to a mode, such as a sleep mode, when the electronic device is bought to the closed configuration. A magnetic sensor can have a detection axis that targets a horizontal component of a magnetic field. A triggering magnetic element can be laterally offset relative to the magnetic sensor. The magnetic sensor can also be a magneto-resistive sensor. The electronic device can also include a second set of magnetic sensor system to confirm when the electronic device is brought to the closed configuration.

    Abstract: A portable computing device that includes a base portion that carries an audio module and a display housing that carries a display is disclosed. The display housing is coupled with, and rotatable with respect to, the base portion. The display housing includes a magnet, and the base portion includes a magnetic field sensor that detects an external magnetic field of the magnet. The magnetic field sensor provides a signal that deactivates the display. In order to reduce layout changes in the portable computing device, the magnetic field sensor is positioned in an audio housing that carries the audio module. However, the magnetic field sensor is designed and oriented to detect the magnetic field from the magnet in the display housing and effectively ignore magnets associated with the audio module. In order to reduce the amount of electrical connections, the magnetic field sensor is electrically coupled to the audio module.

    Abstract: An automated magnet quality measurement system includes a magnet measuring component and an automated magnet moving component. The magnet measuring component can be configured to measure EMF for a plurality of magnets. The automated magnet moving component can move each of the plurality of magnets into and out of the magnet measuring component without requiring any manual intervention, with only one of the plurality of magnets being within the magnet measuring component at a given time. The magnet measuring component can be a Helmholtz coil and the automated magnet moving component can be a rotating disk. The overall system can also include a loading system configured to load each of the magnets onto the automated magnet moving component on an individual and sequential basis, and a sorting system configured to sort the magnets based upon their EMF measurements.

    Abstract: This application relates to an assembly technique for joining parts using a magnetic adhesive. A liquid adhesive including magnetic particles is provided, the liquid adhesive having sufficient properties that allow the adhesive to flow under the influence of a magnetic field prior to curing. A method for joining parts includes the steps of applying an adhesive to a substrate at a location corresponding to the joint, placing a magnetic element proximate the joint to generate a magnetic field that interacts with the magnetic particles in the adhesive to cause the adhesive to flow in a direction corresponding to the magnetic field, and curing the magnetic adhesive under the influence of the magnetic field. An assembly fixture for joining parts includes a magnetic element and, optionally, an inductive heating element. The assembly technique can be used to form a housing of an electronic device from two or more components.
