Abstract: Computational methods and systems that estimate time remaining and right size for usable capacities of resources used to run virtual objects of a distributed computing system are described. For each stream of metric data that represents usage of a resource of a distributed computing system, a model for forecasting metric data is determined and used to compute forecasted metric data in a forecast interval. A resource utilization metric is computed from the forecasted metric data and may be used to estimate a time remaining before the usable capacity of the resource is expected to be insufficient and the resource usable capacity is adjusted. The resource utilization metric may be used to determine the capacity remaining is insufficient. A right-size usable capacity for the resource is computed based on the resource utilization metric and the usable capacity of the resource is adjusted to at least the right-size usable capacity.

Abstract: The invention provides impedance matching circuitry for adjusting an impedance match between a source impedance (2) and a load impedance (4), the impedance matching circuitry comprising: tapered transmission line circuitry which comprises one or more tapered transmission lines (10) coupled or couplable between the source impedance and the load impedance; and a controller (20) in communication with the tapered transmission line circuitry and configured to adjust one or more impedances of the tapered transmission line circuitry to thereby adjust an impedance match between the source impedance and the load impedance.

Abstract: The invention provides wireless communications apparatus comprising: a wireless communications device comprising: an antenna module; circuitry in communication with the antenna module; a circuit interface within the circuitry or between the circuitry and the antenna module; and impedance matching circuitry configurable to adjust an impedance match at the circuit interface; and a controller in data communication with a memory storing a user profile associated with the wireless communications device, or with a user of the wireless communications device, the user profile comprising configuration data relating to one or more impedance matching configurations of the impedance matching circuitry, the configuration data being associated with one or more parameters of the wireless communications device, wherein the controller is configured to use configuration data from the user profile to configure the impedance matching circuitry responsive to a determination of one or more parameters of the device associated with

Abstract: A portable speaker system for use with a laptop computer is configured for attachment to a screen of a laptop computer or alternatively for a free standing configuration. The speaker system includes an acoustic chamber for containment of the sound reproducing mechanism, a second chamber, and a damped hinge mechanism for movable connecting the acoustic chamber and the second chamber.
