20090177466DETECTION OF SPEECH SPECTRAL PEAKS AND SPEECH RECOGNITION METHOD AND SYSTEM - The present invention provides a method and apparatus for detecting speech spectral peaks and a speech recognition method and system. The method for detecting speech spectral peaks comprises detecting speech spectral peak candidates from power spectrum of the speech, and removing noise peaks from the speech spectral peak candidates according to peak duration and/or peak positions of adjacent frames, to detect speech spectral peaks. In the present invention, reliable speech spectral peaks can be obtained by removing noise peaks using the limitations of peak duration and adjacent frames in the detection of the speech spectral peaks. Further the energy values of the speech spectral peaks are used to extract the MFCC feature of speech instead of a sample sequence of the whole power spectrum in the conventional technique, the noise robustness of speech recognition can be enhanced while not increasing the speech feature dimensions.07-09-2009

20100148553MODULAR CHILD RESTRAINT SYSTEM - A modular child restraint system for use in vehicles comprises a base and interchangeable attachable seats where the seats are for different stages of childhood development. The system can further comprise additional bases adapted to other uses such as strollers and infant swings. A common engagement mechanism allows the various seats to be moved from one base to another. One such system comprises a base and a seat configured to rotate relative to one another when engaged. The seat can also lock in a position relative to the base. The base includes a visual indicator to show that the seat is secured to the base.06-17-2010

20100319411SELF-STEAMING BENEFIT COMPOSITION - Self-steaming benefit compositions for treating fabrics. The present invention relates to compositions which are both self-steaming and include one or more benefit agents to provide benefits to fabrics. The present invention also relates to a method for treating fabrics utilizing the self-steaming benefit compositions of the present invention.12-23-2010
20110074195ACTIVELY SECURABLE BASE FOR A MODULAR CHILD RESTRAINT SYSTEM - A child restraint system for use in vehicles comprises a seat portion and a base. The base secures the child restraint system to a vehicle seat with a vehicle restraint such as a seat belt or a LATCH system. The base both engages the vehicle restraint and includes a force-multiplying mechanism for tensioning the vehicle restraint. Tensioning the vehicle restraint secures the base by forcing the base against the vehicle seat. An embodiment of the base includes a platform configured to rest on the vehicle seat, an upright member joined to the platform, and a tensioning device, including a force-multiplying mechanism, for tensioning the vehicle restraint.03-31-2011
20110101742EXTENDABLE SUNSHADE FOR CHILD CAR SEAT - An all weather sunshade system for infant carriers includes a main sunshade that is pivotally attached to the infant carrier and an integrally provided sunshade extension. The main sunshade is selectively deployable and includes curved semi-rigid members which support a fabric material and includes a front edge. A rear edge of the sunshade extension is secured along the front edge of the main sunshade structure and is sized and shaped so that it may be selectively drawn forward, when the main sunshade is fully deployed, and secured around a front portion of the infant carrier. In doing so, the sunshade extension remains taut following the contours defined by the shape of the front edge of the main sunshade and the perimeter shape of the front edge of the infant carrier.05-05-2011
20110115264CHILD RESTRAINT SYSTEMS - Improvements for child restraint systems are directed specifically to the covers, handles, and harnesses thereof. A child restraint cover is readily removed without having to detach the harness from the seat. A soft and semi rigid child restraint handle includes members that are tied together in a crossover fashion. Another handle of the invention spans above the restraint in a head to foot direction. A further handle design includes dual integrated handles. 5-point and 7-point harnesses that do not require threading a child's limbs through harness loops are also provided. A harness height adjuster is also described.05-19-2011

20090302578MULTIPLE INTERFACE STROLLER APPARATUS AND SYSTEMS - An apparatus and method for adding an interface to a stroller is described. The apparatus may include a frame supporting a mounting interface for engaging an interface of the stroller, and first and second interfaces, each operable for receiving a removable seating surface. Such an apparatus may be mounted on the interface of a stroller designed to have a single interface for a seat, thereby providing two interfaces for seats. In another example, an apparatus for adding an interface may include an interface for receiving a removable seating surface and a frame operable for attaching to a stroller and supporting the interface. The apparatus may further include an attachment mechanism for attaching to the frame of the stroller and wheels. Such an apparatus may attach to a stroller designed to have a single interface for a seat, thereby introducing at least one more interface for a second seat.12-10-2009
20100109270RIDE ALONG BOARD FOR BABY STROLLER - A baby stroller system is provided including a baby stroller and a ride along board attached thereto for supporting a rider (e.g., a child) while the stroller is pushed. The ride along board may include a platform for the rider to stand upon and at least one wheel for supporting the platform. Additionally, the ride along board is positioned asymmetrically relative to the stroller, e.g., in-line with one of the rear wheel or laterally outside of the stroller wheel base. Further, the platform may be positioned laterally outside of the handlebars, thereby providing more room for the rider (e.g., not having to stand or squeeze between the handlebars) and moving the ride along board and rider away from the moving space of a user pushing the stroller. The ride along board further includes at least three wheels defining a ride along board wheel base, where a center of mass of the ride along board is within the wheel base. The ride along board may be attached to opposing ends of an axle of one of the rear wheels.05-06-2010
