Abstract: Techniques are described to reduce false alarms in network devices utilizing keepalive messaging schemes. In order to potentially avoid false alarms, a transmitting network device adjusts quality of service QOS/TOS settings in keep-alive probe packets that are sent later in a current detection interval such that the keep-alive probe packets have escalating priorities. In addition, for keep-alive probe packets that are sent later in the current detection interval, the network device may also insert host-level preferential indicator within each of the packets to request preferential treatment at both itself and the peer network device.

Abstract: Disclosed herein is an low power output stage coupled between a supply node and a ground node, configured to drive an output, and controlled by first, second, and third control nodes. A current sinking circuit controlled by an input signal and configured to sink current from the first and second control nodes when the input signal transitions to a first logic level, thereby resulting in decoupling of the output stage from the ground node and sourcing of current to the output by the output stage. When the input signal transitions to a second logic level different than the first logic level, the current sinking circuit sinks current from a third control node, thereby resulting in decoupling of the output stage from the supply node and sinking of current from the output by the output stage.

Abstract: Techniques for securely destroying data stored on a portable storage device may be provided. For example, a portable storage device includes a first memory configured to store data while a current is supplied by a second device or a capacitor of the first device. One or more capacitors of the portable device may be configured to store a charge to provide the current to the first memory. A processor that is configured to access computer-executable instructions of a second memory of the first device may provide instructions to enable transfer of the data stored in the first memory to the second device. In particular embodiments, the data stored in the first memory may be erased in response to the current no longer being provided by the second device or the one or more capacitors.

Abstract: A circuit has a first window comparator determining whether a signal at a first input has a voltage higher than a first threshold but lower than a second threshold, and a second window comparator determining whether a signal at a second input has a voltage higher than the first threshold but lower than the second threshold. A logic circuit generates pulses in response to either the first window comparator determining that the signal at the first differential input has a voltage higher than the first threshold but lower than the second threshold or the second window comparator determining that the signal at the second input has a voltage higher than the first threshold but lower than the second threshold. A filter circuit receives the pulses from the logic circuit and generates a flag indicating that the signal is invalid, based upon pulses received from the logic circuit.

An example method includes displaying an orbit visualization characterized by a first state, wherein the orbit visualization includes a parent node and one or more child nodes positioned about a first orbit path that at least partially circumscribes the parent node; selectively initiating navigation of the orbit visualization; transitioning display of the parent node and one or more child nodes in accordance with the navigation by animating repositioning of the parent node and the one or more child nodes on a user interface display screen, such that a resulting node positioning characterizes the orbit visualization in the second state representative of a navigated-to location. The navigation may represent a downward or upward navigation of hierarchically related data, such that the animation illustrates separation of one or more petals from a selected node or movement toward the selected node, respectively.

Abstract: Embodiments presented herein describe a package management system that uses guidance devices when transporting packages. In one embodiment, the package management system includes an event detecting device that detects a package transporting event such as when a package is sorted into a container, a container is moved from the warehouse to vehicle, a container is moved from a vehicle into a warehouse, a package is delivered, a package is moved to a staging location, or a package is picked-up from a staging location. Once a container or staging location corresponding to the event is identified, a gateway identifies the guidance device assigned to that container or staging location and instructs the guidance device to illuminate a light disposed thereon.

Abstract: A process and temperature variation operating condition that is globally applicable to an integrated circuit die is sensed in a core circuit region to generate a global process and temperature compensation signal. A voltage variation operating condition that is locally applicable to an input/output circuit within a peripheral circuit region of the integrated circuit die is sensed to generate a local voltage compensation signal. More specifically, the localized voltage operating condition is generated as a function of a measured difference in frequency between a first clock signal generated in the peripheral circuit region in response to a supply voltage subject to voltage variation and a second clock signal generated in the core circuit region in response to a fixed bandgap reference voltage. The operation of the input/output circuit is then altered in response to the global process and temperature compensation signal and in response to the local voltage compensation signal.

Abstract: A power supply voltage detector circuit monitors a ramping supply voltage and selectively enables a voltage divider for operation to divide the ramping supply voltage in response to the ramping supply voltage exceeding a first threshold. Additionally, a variable resistance of the voltage divider is changed in response to the ramping supply voltage exceeding a second threshold. A voltage output from the voltage divider is used to generate a bandgap voltage used as a reference voltage in comparison operations for controlling enabling of the voltage divider and selection of the variable resistance.

Abstract: A chain visualization shows cards representing first, second and third hierarchical data items from a database. The second data item descends from the first. The third descends from the second. The visualization shows an ancestors chain, a descendants chain, and an active item location where the chains meet. The visualization shows a card visually associated with the ancestors chain for the first data item, a card in the active item location for the second data item, and a card visually associated with the descendants chain for the third data item. The cards present information from the data items. When a card is activated, it moves to the active item location. A descendant data item, descending from the new active item, is retrieved from the database. A card representing the descendant data item is displayed as visually associated with the descendants chain.
