Abstract: Exemplary methods, apparatuses, and systems include receiving time series data for each of a plurality of performance metrics. The time series data is sorted into buckets based upon an amount of variation of time series data values for each performance metric. The time series data in each bucket is divided into first and second clusters of time series data points. The bucket having the greatest distance between clusters is used to determine a performance metric having a greatest distance between clusters. The performance metric having the greatest distance between clusters is reported as a potential root cause of a performance issue.

Abstract: Disclosed is a transition apparatus for transitioning wide frequency band electromagnetic waves between the metal waveguide and the laminated waveguide. The transition apparatus includes a top conductive layer, a bottom conductive layer, a conductive wall, and a transition interior. The conductive wall is formed along a substrate of the laminated waveguide and electrically connected the top conductive layer and the bottom conductive layer. The transition interior is defined by the top conductive layer, the bottom conductive layer, and the conductive wall. The conductive wall further comprises a plurality of stubs extending from an inner side of the wall into the transition interior, the plurality of stubs divide the transition interior into three or more resonator cavities for transitioning wide frequency band electromagnetic waves between the metal waveguide and the laminated waveguide.

Abstract: A method and apparatus for a mobile personal computer (MPC) system with built-in scanner. In one embodiment, the method includes detection of the insertion of an item within a paper feed tail exposed on an exterior surface of the MPC system. In one embodiment, if insertion is detected when the MPC system is in a sleep state, a disabled scanner device is enabled to scan the item to capture an item image. Subsequently, the item image may be processed to identify the item as, for example, a business card. In one embodiment, an item image may be further processed to extract contact information from the item image. In one embodiment, when item insertion is performed during a sleep state, subsequent to completion of extraction of the contact information, components of the system awoken during the sleep state may resume the sleep state. Other embodiments are described and claimed.
