Managing multiple profiles for a single account in an asynchronous messaging system
Multiple profiles are received in association with a first user account in an asynchronous messaging system. One or more of the profiles are associated with other user accounts. The associated profiles are transmitted to user clients associated with the other user accounts for storage as a local copy. The association may include inclusion in a contact list of the first user, or a contact list of the other users. The associated profiles are transmitted when messages are sent from the first account to the other user clients, or the profiles are created or updated. A public profile may include a version identifier which is updated when the public profile is updated. Updates to local copies of the public profile at other user clients may occur only when a local copy of the associated version identifier indicates that the local profile is outdated, thereby reducing network traffic. |

Continuous tuning of digitally switched voltage-controlled oscillator frequency bands
A phase locked loop (PLL) control system includes a voltage-controlled oscillator (VCO) circuit including an inductor and a plurality of capacitors arranged in parallel with the inductor. Digitally enabling or disabling the capacitors in a thermometer coded manner via switches creates tuning states that provide additional frequency range, and each has a limited range of VCO frequency tuning.

The slow transition between tuning states allows the PLL to remain in lock, useful under changing operating conditions. Specifically, under changing operating conditions, digital logic detects the PLL tuning control voltage approaching the edge of a VCO band and will add/reduce VCO capacitance effectively transitioning into the adjacent VCO band while the PLL maintains lock via its normal feedback loop. |

Methods for self-heating induced healing of metal dendrites
A method of prolonging service life of an energy storage device such as a lithium-ion battery includes temporarily operating the battery at an elevated current density.

Operating the battery in bursts at the elevated current density results in self-heating at the anode surface that merges adjacent lithium-metal dendrites and an overall smoothing of the anode surface. This method is also applicable to other alkali-metal-based batteries and chemistries. |
