  • Patent number: 10374519
    Abstract: The present disclosure discloses an LLC resonant converter and a method for suppressing ripples in output voltage of the LLC resonant converter. The LLC resonant converter comprises: a half-bridge or full-bridge chopper having a driving circuit, an inductance-capacitance series resonant network coupled to the chopper, an isolation transformer coupled to the resonant network, and a rectification and filtering circuit coupled to the isolation transformer; a feedforward controller coupled to generate a feedforward signal based on an input voltage; and a controlled oscillator coupled to receive the feedforward signal from the feedforward controller and to control an operating frequency of the chopper via the driving circuit based on the feedforward signal. Thus, a feedforward correction is provided for the LLC resonant converter, so that ripples in a DC output voltage of the LLC resonant converter are reduced.

  • Patent number: 10191535
    Abstract: The embodiments discussed herein relate to systems, methods, and apparatus for controlling power consumption of a computing device in a standby or sleep mode. During the standby or sleep mode an external device can be plugged into the computing device. The external device can be provided power from a standby power supply until a determination is made as to whether a main power supply is operating. The determination can be based on comparing the output of the main power supply to an output of the standby power supply. If the main power supply is operating, a switch in the computing device can close to allow the main power supply to provide power to the external device. Moreover, in some embodiments, the switch can close based exclusively on a current demand of the external device from the standby power supply.

  • Publication number: 20180332560
    Abstract: Systems and methods for regulating alerts in a wearable device are disclosed. The alerts may be generated from a mobile device or a wearable device communicatively coupled to the mobile device. The system may include an alert storage module that receives alerts of various types, and generate a plurality of alert heaps each including respective one or more alerts. The system may determine for an alert a respective cost value associated with issuing a notification of the alert. The alert heaps may be merged to produce a cost-biased leftist heap including prioritized alerts based on the cost values of the alerts. The system may generate a queue of notification commands based on the prioritized alerts, and transmit the commands to the wearable device.

  • Patent number: 9882214
    Abstract: An improved method of forming a precipitated transition metal salt useful to make a lithium transition metal oxide useful for making a lithium ion battery comprises the following. A transition metal solution comprised of a dissolved transition metal salt in water and an alkali solution comprised of an alkali salt dissolved in water are introduced into a reactor having an inlet and an outlet connected by a tubular member having therein packing. The rate in which said solutions are introduced are such that the pH of the overall solution in the reactor has pH of 5 to 12 and the time of reaction (mere seconds to several minutes) in the reactor is sufficient to form a precipitated transition metal salt in an effluent liquid. The transition metal salt precipitate in the effluent is discharged from the reactor and the salt separated from the effluent, where it can be purified by washing and dried and subsequently heated with a lithium compound to form a lithium metal oxide useful for making lithium ion batteries.

  • Publication number: 20170090814
    Abstract: Technology described herein provides methods whereby a two-level indexing/hashing structure is used to efficiently coordinate storage of sensor measurements between local digital memory (e.g., at a mobile device) and remote digital memory (e.g., at a cloud storage system). The first level of the two-level indexing/hashing structure may be include an array of first-level nodes that are sorted according to priority values. The priority values may be determined based on user data-querying activity. The second level of the two-level indexing/hashing structure may include second-level hash tables wherein buckets are associated with memory blocks of a predefined size. Sensor measurements that were taken during a specific time period may be stored near each other in memory and may be downloaded for local storage if user activity suggests that the user frequently has interest in data from that time period.
