Abstract: Systems, methods, and computer-readable media provide multiple modes of haptic feedback for an electronic device using a single haptic actuator. Adjusting a parameter (e.g., frequency) of an actuator waveform generated by the single haptic actuator may affect how a mechanical coupling between the haptic actuator and a portion of the electronic device produces a device waveform at that device portion from the actuator waveform. A first mechanical coupling with a first response characteristic (e.g., stiffness or resonance frequency) may be provided between the haptic actuator and a first portion of the electronic device (e.g., a user input component of the electronic device), while a second mechanical coupling with a different second response characteristic may be provided between the haptic actuator and a second portion of the electronic device (e.g., the device housing of the electronic device) to selectively provide localized haptic feedback at the first portion of the electronic device.

Abstract: A module includes a permanent magnet biased electromagnetic haptic engine, a constraint, and a force sensor. The force sensor includes a stator and a shuttle. The constraint is coupled to the stator and the shuttle. The force sensor is at least partially attached to the permanent magnet biased electromagnetic haptic engine and configured to sense a force applied to the module. The constraint is configured to constrain closure of a gap between the stator and the shuttle and bias the shuttle toward a rest position in which the shuttle is separated from the stator by the gap.

Abstract: Systems, software, devices, and methods of distributing a workload among available data storage devices in a thermal aware manner are described herein. More specifically, the examples herein discuss distributing the workload among the available data storage devices in a thermal aware manner that optimizes collective IOPs of the data storage devices in an enclosure. The thermal aware distribution of the storage operations is determined by a thermal model that predicts thermal characteristics of the data storage system based on inlet air characteristics of the enclosure, performance characteristics and thermal constraints of the data storage devices, and constraints of the workload.
