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: This application relates to improving kinematics in a computing device such as a laptop computer. A magnetic latch mechanism includes a magnetic array and an attractor plate. The magnetic array is secured in a top portion of the laptop computer and the attractor plate is secured in a base portion of the laptop computer. An attractive force of the magnetic latch mechanism is calibrated by selectively demagnetizing a portion of one or more magnetic elements in the magnetic array to reduce the attractive force proximate a target force. The calibration technique can include exciting a demagnetizing element, such as a pair of conductive coils, with a short, high frequency demagnetization pulse to create a demagnetized zone within the magnetic array that is completely demagnetized, irrespective of unit to unit variations of magnetic properties in the initially magnetized magnetic array. This technique ensures an accurate kinematic user experience.

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: A computing device is disclosed. The computing device includes a shock mount assembly that is configured to provide impact absorption to sensitive components such as a display and an optical disk drive. The computing device also includes an enclosureless optical disk drive that is housed by an enclosure and other structures of the computing device. The computing device further includes a heat transfer system that removes heat from a heat producing element of the computing device. The heat transfer system is configured to thermally couple the heat producing element to a structural member of the computing device so as to sink heat through the structural member, which generally has a large surface area for dissipating the heat.

Abstract: This application relates to a portable electronic device. The portable electronic device includes a housing including (i) a lower case, and (ii) an upper case pivotally coupled to the lower case with a hinge assembly. The housing includes a processor capable of providing instructions, an operational component in communication with the processor, where the processor is capable of executing a function, and a magnetic detection system included within the hinge assembly. The magnetic detection system includes a magnetic element capable of generating a magnetic field, and a magnetic sensor capable of determining an angle between the lower case and the upper case based on the magnetic field, where when the processor determines that the angle between the lower case and the upper case satisfies a predetermined threshold angle, the processor provides the instructions to the operational component to execute the function.

Abstract: An electronic device (such as a laptop) may selectively latch a base to a lid using a switchable magnet array. In particular, a drive circuit in the electronic device may apply at least a current pulse to a conductor that generates a magnetic field to reverse a direction of a remnant magnetization in the switchable magnet array. By reversing the direction of the remnant magnetization, the electronic device may selectively increase or decrease a magnetic field generated by the switchable magnet array at an attraction plate in the electronic device. This magnetic field may, in turn, result in an attractive force between the switchable magnet array and the attraction plate, thereby selectively latching the base and the lid when the base and the lid are proximate to each other.
