International Classification:

H03K005/159

US Classification:

Abstract:

An adaptive controller generates a sequence of dither signals for each of a plurality of control parameters. Each dither signal sequence is uncorrelated with every other dither signal sequence. Each nominal control signal has the first of its respective dither signal values simultaneously summed with it to form the control parameter values used by the controller. Updated control signals are applied in parallel to the controller outputs and a performance measure is taken and stored. The second signals in the dither control sequences are then summed with their respective nominal controls and applied in parallel to the controller and a second performance measure is taken and stored. This process is repeated for the length of the dither control signal sequence to yield a sequence of performance measurements. The sequence of performance measurements is correlated with each of the dither sequences, forming sequences of correlator outputs, one for each control signal. Each correlator output sequence is integrated and, depending upon the value of a correlator's integration output, the corresponding nominal signal has it's dither value added to or subtracted from it to form the respective, updated control values.

International Classification:

A61B 17/08

US Classification:

606153, 606151

Abstract:

Described here are devices and methods for intussuscepting a portion of stomach tissue. Typically the intussusception is created at a position near, but distal to the gastroesophageal junction, and a pouch capable of storing a volume (from about 0 cc up to about 100 cc) is created proximal the intussuscepted tissue. In this way, the amount of food that may be ingested is reduced, helping to ameliorate GERD symptoms, and aiding in weight loss efforts. Some of the devices described here include an expandable member and at least one suction inlet. In these devices, the expandable member is expanded to create a proximal cavity into which the stomach tissue is pulled (e. g. , using suction), thereby creating the intussusception.

International Classification:

US Classification:

369 5315, 369 5316, 369 5342, 360 53

Abstract:

The present disclosure is directed to selectively protecting a portion of a track including a plurality of data sectors. The data sectors include a plurality of user sectors and one or more parity sectors. Protected bits are designated in each of the of data sectors. The protected bits are selected to have matching bit indices across the data sectors resulting in a parallel alignment of the protected bits across the user and parity sectors. One or more selections of protected bits of the user sectors are encoded across matching bit indices to generate data values in the corresponding protected bits of the parity sectors. At least one portion of at least one failed sector is recoverable by decoding at least one selection of the protected bits when a sector error occurs at a protected bit.

US Classification:

714819

Abstract:

Various embodiments of the present invention provide systems and methods for data processing. As an example, a data processing circuit is disclosed that includes a noise injection circuit. The noise injection circuit is operable to: determine a difference between a first data output and a second data output to yield an error; and augment an interim data with a noise value corresponding to the error to yield a noise injected output. The interim data may be either the first data output or the second data output.

International Classification:

US Classification:

606153

Abstract:

The present invention is an improved separating device for providing the malabsorptive component of a minimally invasive weight reduction system. This device may be a sleeve, liner, or tubular sheath that alters absorption of compositions through walls of hollow organs (stomach, intestines). The improvement involves better long-term retention through the ability of the device to engage with the interserosal fibrotic tissue formed in an intussusception. The separating device may be a distal extension of a retaining member that is directly engaged with and retained by intussuscepted tissue. Intussusception shrinks a hollow organ to provide a volume reducing restrictive component of a weight reduction system. Securing the separating device to an intussusception avoids retention problems of reference art devices as interserosal fibrosis helps secure the device. Also provided are an apparatus for retaining the device, a device and method for delivering the separating device, and a method for removing it.
