  • Publication number: 20200067327
    Abstract: Systems and methods for reuse of battery pack-side current and voltage sensing are disclosed. By reusing elements within a battery pack, a battery field effect transistor (FET) within a power management integrated circuit (PMIC) may be eliminated or at least bypassed. In a first aspect, a current mirror is coupled to a charge protection circuit in the battery pack to capture a sensed current. Likewise, a voltage sensor captures a voltage level for a charging path. Current and voltage are output to the PMIC for use in regulating a buck charger. In a second aspect, current data and voltage data are collected and digitized before being sent to the PMIC for use in regulating the buck charger.

  • Patent number: 10489324
    Abstract: Systems and methods for port management are disclosed. In one aspect, the system may consolidate port management functions as well as power conversion, protection features, and signal conditioning circuitry into a single integrated circuit (IC) for a device without a battery. Further exemplary aspects allow for arbitration between ports to handle power supply versus power sink functions. Still further exemplary aspects provide an indication when a weak power source is coupled to the computing device to alert a user that the weak power source may not provide sufficient power for full operation. Such consolidated functionality allows a single form factor to be used for all ports whether the ports are used as a power port or an output port. Further, such consolidated functionality helps mitigate possible damage caused by improper activity.

  • Patent number: 10431939
    Abstract: Over-voltage protection systems and methods are disclosed. In one aspect, a biasing circuit is added to a pre-existing clamp required by the Universal Serial Bus (USB) Type-C specification at a configuration control (CC) pin. The biasing circuit turns the pre-existing clamp into an adjustable clamp that dynamically adjusts to over-voltage conditions. In an exemplary aspect, the biasing circuit may include a biasing field effect transistor (FET) and a pair of switches that selectively couple the pre-existing clamp and the biasing FET to fixed voltages such that the CC pin is maintained at an acceptable voltage. In another exemplary aspect, the biasing circuit may omit the biasing FET and rely on two switches that selectively couple the pre-existing clamp to fixed voltages such that the CC pin is maintained at an acceptable voltage.

  • Patent number: 10343801
    Abstract: A method of sealing a peelable lid (2) to a flange (4) provided within a metal can body (1) which involves inserting an induction coil (6) into the can body to primarily heat the sealing surface (5) of the flange, while keeping the exterior wall of the can relatively cool to avoid tin reflow and decoration degradation of the exterior wall. The induction coil is subsequently removed from the can body and a peelable lid applied to the flange, whereby residual heat in the flange aids the sealing of the lid to the flange, e.g. by allowing activation of a bonding material.

  • Publication number: 20190190284
    Abstract: An apparatus is disclosed for open-loop limiting of a charging phase pulsewidth. An example apparatus includes an input node, an output node coupled to a battery, a flying capacitor coupled to the output node, a driver circuit, a charging circuit, and an open-loop charging phase pulsewidth limiter coupled to the driver circuit and the charging circuit. The driver circuit generates a charging phase signal based on a clock signal. Using at least one switch that is coupled between the input node and the flying capacitor, the charging circuit connects or disconnects the flying capacitor to or from the input node based on the charging phase signal. The open-loop charging phase pulsewidth limiter monitors for at least one limit event associated with charging the battery with the flying capacitor. Responsive to detection of the limit event, the open-loop charging phase pulsewidth limiter limits a pulsewidth of the charging phase signal.

  • Publication number: 20180314034
    Abstract: The present invention provides strategies for mitigating the deleterious effects of differential thermal expansion in composite panel structures. The principles of the present invention are particularly useful in the field of concentrating solar power. The principles of the present invention can be used in CSP applications to make composite mirror panel structures with improved characteristics for accommodating differential thermal expansion between components of the composite. Significantly, the composite mirrors structures can still be securely attached to other heliostat components such as a drive mechanism while still having the ability to accommodate differential thermal expansion between the skins of a composite mirror panel helps to limit energy losses due to slope errors.

  • Publication number: 20180129015
    Abstract: In illustrative modes of practice, heliostat devices integrate light reflecting panels with a composite supporting structure that helps to provide the resultant assembly with structural integrity and stiffness. Light reflecting panels are coupled to the supporting, composite structure by a plurality of flexible connecting elements. Advantageously, the composite approach of the present invention effectively separates structural and thermal compensation functions. Specifically, the composite support structure helps to provide desired structural properties. In the meantime, the flexible connecting elements couple the top, light reflecting panel to the support structure in a manner that helps to isolate the top, light reflecting panel from thermal stresses that otherwise could cause undue slope errors.

  • Publication number: 20180129821
    Abstract: An application running in a container is able to access files stored on disk via normal file system calls, but in a manner that remains isolated from applications and processes in other containers. In one aspect, a namespace virtualization component is coupled with a copy-on-write component. When an isolated application is accessing a file stored on disk in a read-only manner, the namespace virtualization component and copy-on-write component grant access to the file. But, if the application requests to modify the file, the copy-on-write component intercepts the I/O and effectively creates a copy of the file in a different storage location on disk. The namespace virtualization component is then responsible for hiding the true location of the copy of the file, via namespace mapping.
