Patent application number	Description	Published
20090306972	Dropout Concealment for a Multi-Channel Arrangement - A method conceals dropouts in one or more audio channels of a multi-channel arrangement. The method maps transmitted signals into a frequency domain during an error-free signal transmission of two or more channels. A magnitude spectra and spectral filter coefficients are derived. The spectral filter coefficients relate the magnitude spectrum of the audio channel to the magnitude spectrum of at least one other channel. When a dropout occurs, a replacement signal is generated through the filter coefficients and a substitution signal. The filter coefficients may be generated prior to the detection of the dropout.	12-10-2009
20100266148	TRANSDUCER WITH DEFORMABLE CORNER - A transducer generates acoustic energy. The transducer is suitable for incorporation into any device that needs sound reproduction capability, including devices with generally rectangular geometries such as cell phones, PDAs, and portable gaming devices. The transducer includes a displaceable membrane with a deformable corner. The deformable corner may extend the frequency range over which the transducer generates acoustic energy without distortion. The deformable corner may be part of a membrane periphery around the displaceable membrane. The membrane periphery may be square, triangular, or may take any other polygonal shape.	10-21-2010

20090046032	Telescoping Antenna With Retractable Wire Antenna Element - A telescoping antenna is disclosed having a plurality of telescoping hollow elements, including an inner-most hollow element. A button latches onto the top of the inner-most element. The inner-most element also includes a tab for preventing its full retraction into the other hollow elements. A wire antenna element is connected to the button, extends through the hollow elements, and is operably connected to a retracting mechanism. The button can be detached from the hollow elements in order to extend the wire antenna elements from out of the hollow elements. The wire antenna element is electrically connected to the receiver circuit such that the wire can act as a long-wire antenna of a calculable radio frequency (RF) resonance when extracted to a particular length.	02-19-2009

20090125826	SYSTEMS AND METHODS PROVIDING A DECLARATIVE SCREEN MODEL FOR AUTOMATED TESTING - Systems and methods for a design and runtime environment provide navigation maps using a declarative model defined by recording actual manipulation of a physical or virtual device. The systems and methods may be used to automatically navigate to application screens eliminating need for a test engineer to provide navigation code.	05-14-2009

20090057326	CONTAINER SEAL - A seal for a container of fine particulate materials that includes a sifter insert. The seal comprises a base that is secured over a plurality of holes in the insert by a releasable pressure-sensitive adhesive. A pull tab extends outwardly from an upper surface of said base. The pull tab is fixedly adhered to the upper surface of the base and extends outwardly away from a mid-section thereof. The pull tab is pivotable through 180 degrees about its connection point with the base and remains fixedly secured thereto when a pulling force is applied to the pull tab. The adhesive bond between the base and the insert is weaker than the adhesive bond between the pull tab and the base. Consequently, a pulling force applied to the pull tab removes the base from the insert and permits particulate material to be dispensed through the holes in the insert.	03-05-2009
