Abstract: An integrated circuit (IC) is disclosed herein for adaptive power multiplexing with a power distribution network. In an example aspect, the integrated circuit includes a first power rail, a second power rail, and a load power rail. The integrated circuit also includes multiple power-multiplexer tiles and power-multiplexer control circuitry. The multiple power-multiplexer tiles are coupled in series in a chained arrangement and configured to jointly perform a power-multiplexing operation. Each power-multiplexer tile is configured to switch between coupling the load power rail to the first power rail and coupling the load power rail to the second power rail. The power-multiplexer control circuitry is configured to control a direction of current flow to prevent cross-conduction between the first power rail and the second power rail during the power-multiplexing operation.

Abstract: A context aware system, for use in a mobile device, includes a context change detector (CCD) coupled to a context classifier (CCL). The CCD is configured to receive sensor data and to detect a change in a current context state of the mobile device based on the received sensor data. The CCL is configured to transition from a low power consumption mode to a normal power consumption mode in response to the CCD detecting the change in the current context state. The CCL is further configured to determine a next context state of the mobile device while in the normal power consumption mode.

Abstract: A novel keyboard interface and input method are described. The interface is driven by a dynamic, general-purpose typing and data-entry software application, with a reduced number of keys to minimize screen real-estate requirements, especially for mobile devices. At any given time, the interface presents base characters with built-in key points on or around the base characters that can be selected and/or swiped to generate characters. The key points are strategically placed based on the intuitiveness of such placements, reducing the curve for learning how to use the interface. Its advantage over other methods of input such as handwriting, voice and gesture recognition is that it is less prone to error and privacy issues. The interface occupies a dramatically smaller area of the screen compared to traditional on-screen keyboards and can provide alternate placement as well as transparency to reveal text or images underneath.

Abstract: Systems and methods for producing reference voltages are disclosed. An example bandgap reference circuit includes a core bandgap module that produces a bias control for biasing the gate of a transistor to produce a proportional to absolute temperature current. The core bandgap module may use an operational amplifier that uses auto-calibration to reduce its input offset voltage. A trimming module uses the bias control to produce a proportional to absolute temperature current that is combined with a trim current and supplied to a resistor and diode to produce a trimmed bandgap voltage. The trimmed bandgap voltage is buffered to produce a reference voltage output. The trim current may be set based on a room temperature measurement of the reference voltage output.

Abstract: A series of current repeaters with localized feedback is provided. Each current that precedes a subsequent current repeater in the series is configured to receive a feedback current from the subsequent current repeater and generate an error signal accordingly with a differential amplifier so as to reduce current repetition errors that would otherwise result from an offset voltage in the differential amplifier.

Abstract: Assessing the impact of an incident in a Service Level Agreement (SLA) by a system including a plurality of nodes organized in a hierarchical structure is disclosed. An incident record for an incident related to a service at a first node is received and an actual impact of the incident at the first node is calculated. The calculated actual impact is transferred to a parent node until a root node is reached. The actual impact of the incident is calculated at the parent node and a final actual impact and a total financial impact for the SLA are calculated at the root node. The actual impact at each node, the final actual impact, and the total financial impact are calculated dynamically while the incident is in progress.

Abstract: The invention relates to a driver circuit used to transmit a digital signal from a source device to a destination device. The driver circuit provides a controlled switching time to improve digital signal quality, while reducing electromagnetic interference. In the circuit, a pair of first switches of a first plurality are coupled in parallel between a first current node and respective ones of first and second output terminals. A plurality of pairs of second switches of a second plurality are coupled in parallel between a respective second current node and the first and second output terminals. Timing circuitry applies input signals to the pair of first switches and successive input signals to the pairs of second switches so as to develop a staggered voltage across a load coupled between the first and second output terminals.
