Abstract: Embodiments of the present invention are directed to switched-mode power supply (SMPS) circuits and methods thereof. The SMPS circuit receives information related to a future load change. For example, the information may be received at a decoder (e.g., a serial bus interface (SBI) decoder) from a microprocessor or microcontroller, such as a mobile station modem (MSM). The SMPS circuit may include an analog-to-digital converter configured to sample an output volgatle of the SMPS circuit to determine a time when the future load change occurs. The SMPS circuit may further include a transient recovery circuit (TRC) for stabilizing the output voltage based on the received information when the future load change occurs. For example, the TRC calculates a duty cycle used to transition states of switches of the SMPS circuit to compensate for the future load change.

Abstract: An apparatus for producing a hologram of an object includes a light source that emits an incoherent electromagnetic wave toward the object, and a masking device configured to display a mask, receive the incoherent electromagnetic wave emitted toward the object, mask the received incoherent electromagnetic wave according to the displayed mask, and produce a masked electromagnetic wave. The apparatus also includes an image recording device configured to capture an image of the masked electromagnetic wave, and a processing device configured to convert the image of the masked electromagnetic wave into the hologram of the object. A method for producing a hologram of an object is also described.

Abstract: A device is disclosed that includes a first pin to supply power to a first power domain of an integrated circuit, a second pin to supply power to a second power domain of the integrated circuit, a switching regulator and a controller. The switching regulator is coupled to the first pin to provide a first regulated power supply to the first power domain and is coupled to the second pin to provide a second regulated power supply to the second power domain. The controller is coupled to the first pin and to the second pin to selectively reduce current flow to at least the second pin during a low power event.

Abstract: A fly-eye-like imaging system for seeing objects embedded in scattering media. Objects are recovered from many speckled images observed by a digital camera through a microlens array. Each microlens in the array generates a speckle image of the object buried between two layers of chick breast tissue. In the computer, each image is Fourier transformed jointly with an image of the speckled pointlike source captured under the same conditions. A set of the squared magnitudes of the Fourier-transformed pictures is accumulated to form a single average picture. This final picture is again Fourier transformed, resulting in the reconstruction of the hidden object.

Abstract: A system and method for performing DSL assessments of a telephone line along a prescribed test path is disclosed. The disclosed system includes a loop diagnostic test unit adapted for testing said telephone line using narrow-band and mid-band frequency test signals; a test system controller and a test system server to provide the DSL assessments to a user via an appropriate interface. In addition, the disclosed methods include the basic steps of: accessing the telephone line along the test path that includes selected hardware such as a voice switch test bus, central office splitter, service provider instruments and terminations; ascertaining various line characteristics along the test path using mid-band and narrow-band frequency signals; analyzing the line characteristics to identify line conditions that affect DSL service; and determining the impact of the line conditions on DSL service.

Abstract: The present invention provides electronic methods and apparatus for interactively authoring, sharing and analyzing digital video content. Methods for authoring include displaying visual data, defining each traversal as a time-based sequence of frames and annotating and storing a record of the traversal and its associated audio records. Defining the traversal includes interactively panning the visual data by positioning an overlay window relative to the visual data and zooming in or out by resizing the overlay window. In alternative embodiments, the visual data may be displayed in a rectangular layout or a cylindrical layout. The methods are practiced using an integrated graphical interface, including an overview region displaying the visual data, a detail region displaying current data within the overlay window, and a worksheet region displaying a list of previously stored annotated traversal records.

Abstract: A method for hiding at least one pattern within a visible representation of the other different pattern is presented. The method is carried out by an encoding device and consists of selecting a predetermined key function, and utilizing this function to cerate a binary halftone representation of the visible pattern, in which said at least one pattern is hidden. This halftone representation is such that each cell therein has halftone dots' position distribution corresponding to the gray-level distribution of the at least one hidden pattern. By processing the binary halftone representation by a two-dimensional spatial correlator based on the key function, data representative of the at least one hidden pattern can be extracted.

Abstract: A Fourier hologram with the distribution of a radial harmonic function creates, in the far field, a pseudo non-diffracting beam. The properties of this pseudo non-diffracting beam can be set by appropriate characterization of the radial harmonic function. Various operations can also be carried out to change the position of the beam relative to the focal point. The beam can be shifted in space, twisted, or tilted.
