Abstract: Systems and methods for smart message delivery for message handoff between communication devices and artificial reality systems are provided. In various examples, a communication device or HMD may receive a message initiating a detection of motion(s) and/or position(s) of the communication device and/or the HMD associated with a user with respect to each other. The communication device and/or the HMD may determine a movement level associated with each other, and based on the movement level relative to a predetermined threshold a message delivery process may be determined. If the predetermined threshold is not met, the message may be output to a user via audio and if the predetermined threshold is met, text associated with the message may be presented by the communication device for the user to read.

Abstract: A circuit (40) for use in a mass data storage device (10) has first (44) second (46) current driver circuits for providing write currents to the data transducer (18). The first and second current levels are different, the second current level being lower than the first. The first current driver circuit (44) may be used to apply currents representing user data to the data transducer (18) and the second current driver circuit (46) may be used to apply currents representing servo information to the data transducer (18). In addition, the first (44) and second (46) current drivers circuits may be operated at different frequencies. The first (44) and second (46) current driver circuits additionally may share at least some circuit components (70, 72, 74-75, 64-65), and may operate at different write speeds.

Abstract: A voltage-mode boosting write driver circuit (40) having a pair of voltage boosting PMOS transistor sets (44, 46) coupled to a high current H-switch (42). One set (44) of the boosting PMOS transistors correspondingly pulls output pin HY high, while the other transistor set (46) correspondingly pulls output pin HX high and the other output pin HY low thereby significantly improving the head voltage swing, and also achieving a faster slew rate. Moreover, resistors (R3, R4) of the H-switch are both matched to each other and impedance matched to a flex cable (T0) interconnection impedance, which interconnection is coupled to the thin film head, to thereby eliminate signal reflection such that the write current (Iw) settles quickly with minimum ringing to achieve a high data rate. Moreover, less power dissipation and smaller number of devices used are achieved by making use of existing transient currents of the pre-driver emitter follower stage.

Abstract: A real-time operating system runs on a processor and dynamically manages the power state of individual circuits or resources with the processor. Thus, if a particular circuit is not needed, power to that circuit can be disabled. If a circuit is shut down, any configuration information or other type of data can be saved before powering off the circuit. Power can be re-enabled to the circuit on a responsive or predictive basis and the configuration information and/or data (collectively referred to as “state” information) can be reloaded into the circuit.
