Provided is a platform with backup power and burst load power needs met using a supercapacitor.

Power supply

Systems and methods of limiting peak audio power in mobile devices may include a high pass filter and a burst module to detect a burst load condition in a mobile device. The burst module can also apply the high pass filter to an audio signal of the mobile device in response to the burst load condition to obtain a filtered signal, and transmit the filtered audio signal to a speaker of the mobile device.

Limiting peak audio power in mobile devices

A power management system includes a sensor to detect current output from a battery, a first comparator to compare the battery current to a first reference value, and a burst controller to perform a first power control operation based on said comparison. The power control operation reduces power consumed by the battery in order to cause the battery current to fall below the first reference value. This may be accomplished by reducing or shutting down power to one or more functions or features of a host system that includes or is coupled to receive power from the battery. The host system may include or correspond to a mobile phone and/or any of a number of other electronic devices.

A backplane employed in a switch fabric, having the capability to allow signal communication between at least two modules. Two or more of the modules being adapted to employ different topologies from the following types of topologies: star, dual star, mesh, and cascaded mesh.

A method for dynamic assignment of slot-dependent static network port addresses. Under the method, a slot address and shelf address are determined for a card modular platform board installed in a given slot in a shelf. The slot and shelf addresses are used as inputs to return a unique network address. The unique network address is then assigned as a static network address for the board's network port. The unique address may be provided by an address proxy, including a boot server. Firmware and/or software stored on a board may also be employed to obtain the static network address. The address may be obtained from a pre-configured lookup table, or dynamically determined using an algorithm.

A method and apparatus to manage airflow in a chassis includes one or more airflow restrictor assemblies disposed adjacent a slot within the chassis. The airflow restrictor assemblies can be set in a plurality of positions between a minimum airflow position and a maximum airflow position. The position of the airflow restrictor assembly can be set in accordance with characteristics of the module inserted in the slot. The module characteristics may include power dissipation and airflow resistance.

Disclosed are a system and method of detecting a diode fault among diodes coupled to a plurality of redundant power feeds. A diode short fault may be detected by measuring a first voltage across a first one of the diodes, measuring a second voltage between two nodes including a terminal of the first diode and detecting the diode short based upon the first and second voltages. A diode open fault may be detected by decoupling a first one of the diodes from a power feed and measuring the voltage across the diode.

An incremental bus structure for a modular measurement instrument includes interface connector structural elements interconnecting segments of a system bus. The system bus contains electrically conductive lines with the system bus having at least one subset of N electrically conductive lines. Each interface connector is part of a measurement module and has at least one set of N electrically conductive input and output contacts corresponding with the N electrically conductive lines. The first input contact of the set of N contacts for each connector is coupled to an electronic element associated with its measurement module and the second and subsequent input contacts are connected to the first and subsequent output contacts.

An analog input signal to a digital oscilloscope is sampled and digitized to form a representative waveform data sequence. A waveform is then displayed on a screen of the oscilloscope to represent the magnitude of the waveform as a function of time as indicated by the waveform data sequence. The waveform is formed by a set of vectors, each vector comprising a straight line between two points on the screen at elevations representing magnitudes of two successive input signal samples, and at horizontal positions representing timing of the two samples. The screen provides a display organized into an array of pixels, each of which may be illuminated with variable intensity, and each vector is represented by illuminating pixels having center points bounding the trajectory of the vector on the screen. The intensity of each such illuminated pixel is modulated in accordance with the distance between the pixel and the vector trajectory.

Apparatus for manipulating numerical values stored in a memory comprises a modify device for receiving numerical values from the memory and returning numerical values to the memory. The modify device has at least a first state in which it modifies a numerical value received from the memory in a predetermined fashion before returning the numerical value to the memory and a second state in which it does not modify a numerical value received from the memory in the predetermined fashion before returning the numerical value to the memory. The apparatus also comprises a characterizing device for examining at least some of the numerical values and calculating at least one number that defines a property of the examined numerical values. The characterizing device is connected to the modify device for placing the modify device in the first state or the second state depending on the value of the calculated number.
