Abstract: Mobile management method, system and client. Method includes receiving a DNS query for a host name from an application on client; retrieving reputation data associated with host name from a local cache on client; and determining a policy based on host name and the reputation data. Based on determined policy for the host name, blocking attempted network flows to a host corresponding to host name to produce blocked attempted network flows. Method also includes sending attempted network flow metadata related to the blocked attempted network flows to a collector on client; transmitting the attempted network flow metadata from the collector to a VPN server pool via a VPN tunnel; and producing an anomaly report from the transmitted attempted network flow metadata. The anomaly report includes at least one of anomalies, cohorts, trends, location boundaries, detected network security issues, detected compromised clients and/or optimized network usage.

Abstract: A can comprises a can body (10) and a lid (4). The can body is manufactured using only a single homogeneous piece of material and has an edge that defines a top opening into the can. The can body also has an inwardly directed bead (23), which extends around the body, is adjacent to the can body edge, and defines an inwardly facing sealing surface (24) of substantially constant transverse cross-sectional dimension along an axial extent. The lid defines an outwardly directed sealing surface which abuts the inwardly facing sealing surface presented by the inwardly directed bead in order to seal the lid to the can body. An alternative can body has an inwardly directed pinched or collapsed bead which defines an upwardly facing sealing surface (34) for engagement with a downwardly facing sealing surface of a can lid. The alternative can body additionally has an inwardly directed bead (35) between the can body edge and the pinched or collapsed bead.

Abstract: A copy-on-write union filesystem. A computer system identifies a first filesystem namespace as a mutable layer, and a second filesystem namespace as an immutable layer. The computer system exposes a merged filesystem namespace as a union filesystem that merges the mutable layer and the immutable layer, and that overlays the first filesystem namespace over the second filesystem namespace. The computer system identifies an operation on the merged filesystem namespace that requests to read from a file within the merged filesystem namespace, the file being stored in the second filesystem namespace and not being stored in the first filesystem namespace. The computer system returns a handle referencing a proxy object stored in a system memory. The proxy object includes a mapping to a file object corresponding to the file as stored in the second filesystem namespace.

Abstract: A Universal Serial Bus (USB) Type-C and power delivery port with scalable power architecture is disclosed. In one aspect, at least two circuits for a USB port are consolidated into a single integrated circuit (IC). At least one of the at least two circuits is part of a Type-C port controller (TCPC) group of circuits including sensors associated with detecting whether a voltage and current are present at pins of a USB receptacle. At least the other one of the at least two circuits is selected from a battery-related group of circuits including a battery charging circuit, an over-voltage protection circuit, and a conditioning circuit. The more circuitry integrated into the single IC the more readily scalable the end product is for a multi-port device. Additional circuitry such as a light emitting diode (LED) driver may also be included in the single IC.

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.

Abstract: Universal Serial Bus (USB) cable type detection and control techniques are disclosed. In an exemplary aspect, a device connected to a cable detects whether the cable is a legacy cable (i.e., a Type-A to Type-C cable). If the cable is a legacy cable, the device determines an appropriate current to draw based on whether the cable is compliant with the USB Type-C specification or non-compliant. Additional exemplary aspects of the present disclosure determine whether a connector adaptor has been put on a legacy cable and determines an appropriate current to draw based on the capabilities of the legacy cable. Still further aspects of the present disclosure evaluate not only the cable to see if the cable limits the current draw, but also evaluate a device at a distal end of the cable to verify if and how current may be drawn by such remote device from a mobile terminal.

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.

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.

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.

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.

Abstract: A tubular metal can body having one end for attachment of a removable overcap, the can body having an inwardly projecting flange (1) formed therein by folding the can wall (2) circumferentially, part-way along its length, the flange providing a convex upper surface (8) to which a peelable lid (12) can be sealed.

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.
