A system and method are provided for arranging photographs, drawings, videos and other media elements in a logical and visually appealing manner. Media elements may be selected, automatically or manually arranged in a progression to collectively tell a complete narrative. The arrangement for the progression may provide some direction but not limit the creator to sending single elements at a time, or using templates, pages, folders, or albums. Images may be intelligently placed and/or sized. When viewing the story, a viewer can advance through the media and understand the full story or perspective. A user may resize, move, delete or add images to enhance the story. The story may be shared with others, some or all of which may also collaborate to add or change the story progression to provide different perspectives or content.

A system, processor, and method for multiplying multi-dimensional data, for example, matrices, stored in vector memories. Each data element in a vector memory representing a sequential single element in a row of a left operand data array may be multiplied with a respective vector in a vector memory representing a sequential row in the right operand data array. The memory element representing the left operand element may be multiplied with the memory vector representing the right operand row that is in the same sequential order. A plurality of vectors of product elements may be generated by the multiplying. A single product element from each of the plurality of vectors of product elements may be added to a sum of product elements to generate each respective element in the same sequential order in a row of a product data array to generate a vector of a complete row of elements of the product data array.

A packet network of interconnected nodes employing dynamic backup routing of a Network Tunnel Path (NTP) allocates an active and backup path to the NTP based upon detection of a network failure. Dynamic backup routing employs local restoration to determine the allocation of, and, in operation, to switch between, a primary/active path and a secondary/backup path. Switching from the active path is based on a backup path determined with iterative shortest-path computations with link weights assigned based on the cost of using a link to backup a given link. Costs may be assigned based on single-link failure or single element (node or link) failure. Link weights are derived by assigning usage costs to links for inclusion in a backup path, and minimizing the costs with respect to a predefined criterion.

An electromagnet having a conical bore. The conical bore is created by wrapping a conductor around a conically-offset helix. The cross sectional area of the conductor can be varied in order to maintain a desired current carrying capacity along the helix. A single element can be used as the conductor. The conductor can also be created by stacking a series of specially-shaped plates analogous to prior art Bitter-disks.

A compressive imaging (CI) device including a light modulator and a light sensor (e.g., a single-element sensor or a sensor array). The CI device may support the focusing of light on the light modulator and/or on the light sensor in a number of ways: (1) determining a focus indicator value by analyzing a 1D or 2D image in the incident light field; (2) measuring light spillover between modulator regions and light sensing elements—either at the level of voltage measurements or the level of reconstructed images; (3) measure noise in reconstructed sub-images; (4) measuring an amount high-frequency content in the incident light field; (5) incorporating a range finder to measure distance to the object being imaged; (6) incorporating an image sensor downstream from the modulator; and (7) splitting a portion of the incident light onto an image sensor, prior to the modulator.

A Solid State Power Amplifier (SSPA) for powering a single element of a multi-element antenna, the SSPA comprising:

an RF amplifier, having a signal amplifying path that includes preamplifier, driver amplifier and a power output stage;

an Electronic Power Conditioner (EPC) for providing a variable value of DC voltage for powering the power output stage of the RF amplifier;

a control ASIC for receiving an input power signal of the RF amplifier for providing a voltage control signal to the EPC to determine the value of the DC voltage, the control ASIC addressing an EEPROM holding a collection of control words that define output values of a control output signal for varying values of said input power, such that the value of the DC voltage to the power output stage is varied so as to control the gain compression of the RF amplifier for varying values of input power in order to maintain constant amplifier linearity.

Methods and systems for receiving different types of signal formats from different ultrasound transducers are provided. A base unit of an ultrasound system includes a connector and receiver circuit for connecting with one of multiple different types of transducers. For example, a conventional transducer providing analog information associated with a single element on one receive channel is connected with the connector and receiver circuit. Alternatively, a transducer outputting time division multiplex or other multiplex information representing multiple transducer elements is connected with the connector and receiver circuit. The receiver circuit processes the received information differently depending on the data format. For example, the preamplifier impedance or gain is different for single element signals versus time division multiplex signals. As another example, a low pass filter bandwidth is larger for time division multiplex signals than for signals representing a single element. Receive circuits with an analog-to-digital converter positioned prior to a digital demultiplexer are also included for use with multiplexed data formats. Time division multiplex or other multiplex signals from a transducer array are converted to a digital format prior to demultiplexing. Methods and systems for adapting multiplexing or processing of multiplexed signals are also provided. A test signal or ultrasound signals are transmitted from a transducer to the receiver circuit and analyzed. The multiplexer of the transducer is synchronized with an analog digital converter with selectable delays responsive to the analysis. Coefficients or other filter characteristics of a digital equalizer are selected as a function of the analysis.

Methods, systems, and apparatuses are provided for measuring one or more sinusoidal Fourier components of an object. A structured second radiation is generated by spatially modulating a first radiation. The structured second radiation illuminates the object, The structured second radiation is scaled and oriented relative to the object. The object produces a third radiation in response to the illuminating. A single-element detector detects a portion of the third radiation from multiple locations on the object substantially simultaneously for each spatial modulation of the first radiation and for each orientation of the second radiation. A time-varying signal is produced based on said detected portion of the third radiations. One or more characteristics of the one or more sinusoidal Fourier components of the object are estimated based on the time-varying signal.

Methods and systems are disclosed of sensing an object. A first radiation is spatially modulated to generate a structured second radiation. The object is illuminated with the structured second radiation such that the object produces a third radiation in response. Apart from any spatially dependent delay, a time variation of the third radiation is spatially independent. With a single-element detector, a portion of the third radiation is detected from locations on the object simultaneously. At least one characteristic of a sinusoidal spatial Fourier-transform component of the object is estimated from a time-varying signal from the detected portion of the third radiation.
