Abstract: A cystoscopy splash shield for use during surgery in which a large volume of human liquid is involved.  The splash shield  includes a rectangular shaped transparent plastic sheet with a strip of adhesive along its short edge and a hole present in the approximate middle of the sheet.   The short edge of the plastic sheet is affixed to the torso of the patient by the adhesive strip.  The remaining portion of the shield is draped over the groin area of the patient with overlap over and between the patient's legs.  The shield is positioned so its hole is over the groin area to undergo surgery.  A medical optical instrument may be inserted into the hole which is sealed around its circumference.   As a result, a physician conducting surgery in the groin area is protected from any splashing fluids from the patient.

Title: Linear prediction coefficient generation during frame erasure or packet loss
Inventor: KROON PETER
IPC: G10L19/12
Filed: 1995-02-13
Granted: 1998-10-06
Abstract: A speech coding system robust to frame erasure (or packet loss) is described. Illustrative embodiments are directed to a modified version of CCITT standard G.728. In the event of frame erasure, vectors of an excitation signal are synthesized based on previously stored excitation signal vectors generated during non-erased frames. This synthesis differs for voiced and non-voiced speech. During erased frames, linear prediction filter coefficients are synthesized as a weighted extrapolation of a set of linear prediction filter coefficients determined during non-erased frames. The weighting factor is a number less than 1. This weighting accomplishes a bandwidth-expansion of peaks in the frequency response of a linear predictive filter. Computational complexity during erased frames is reduced through the elimination of certain computations needed during non-erased frames only. This reduction in computational complexity offsets additional computation required for excitation signal synthesis and linear prediction filter coefficient generation during erased frames.

Abstract: In a circuit breaker having a thermal-magnetic trip, the voltage across the bimetal is used to sense load currents. This voltage signal representative of current through the bimetal can be used as an input to an arcing fault detector. The signal is converted to a bandwidth limited di/dt signal. If the magnitude of the di/dt signal exceeds a threshold indicative of the onset of an arc a predetermined number of times within a given interval. the circuit breaker is tripped. The voltage across the bimetal can also be used in other devices requiring a measure of load current such as, for example, a meter or an overcurrent alarm.

Abstract: Information "feeds" received from multiple information sources are aggregated, re-formatted and stored in a personalized real time information display system. When the display system receives a request from a user having a personal computer or other similar display device, the system is arranged to respond with information needed to display a screen saver that includes personalized, up to date information, such as traffic, weather and sports, that is of interest to that particular user. Each user has a personalized user profile indicating (a) the categories or types of information that the user desires to receive, such as sports information, weather, investment advisories, and son on, and (b) parameters that specify, for that user, the exact information desired to be received in each category.  If the user's personal computer display has remained inactive for a predetermined period of time, the screen saver is activated, causing the personal computer to access the service node, and after interchange of prestored user identification and password data, retrieve information, obtained by the system from a variety of sources, based on the user's individual profile. The retrieved information is displayed on the screen without interrupting the screen saver function, and the displayed personalized data is thereafter updated in the same manner, at user-specified time intervals.

Title: Optimal disparity estimation for stereoscopic video coding
Inventor: LIU VINCENT
IPC: H04N13/00
Filed: 1997-07-31
Granted: 2001-06-12
Abstract: Disparity estimation between the right and left view pixel luminance values in a stereoscopic video signal is optimized by determining the minimum least-square-error between macroblocks of the right and left view pictures. Affine transform coefficients and disparity vectors which correspond to the minimum error are also determined and transmitted in the data stream for use by a decoder in reconstructing the right view picture.  The scheme can be implemented either locally, at the macroblock level, or globally, at the picture level.  At the macroblock level, least-square-error optimization may occur for each individual macroblock in the right view picture.  In this case, affine transform coefficients are provided for each macroblock. At the picture level, the sum of the least-square-errors is minimized after the blocks of the right view picture are matched to the left view picture.  In this case, only one set of affine transform coefficients are required for the entire right view picture.  Or, block matching between an affinely transformed left view picture and the right view picture may be performed after minimizing the sum of the least-square-errors. The scheme is particularly useful in minimizing the effects of cross-channel luminance imbalances due to camera variations and scenes with significant changes in brightness or contrast, and is compatible with stereoscopic video systems such as the MPEG Multi-view Profile (MVP) system.

Abstract: A method and apparatus for generating various tire profiles. A linear-linear- rotary table carries a non-contacting probe that sequentially scans the entire outer surface of a tire. The non-contacting probe collects measurement data which is transferred to a processor to generate an average cross-sectional tire profile or a high definition cross- sectional tire profile of the tire being measured. The processor, in conjunction with the non- contacting probe, provides an automatic ranging feature which eliminates the need to manually adjust the non- contacting probe prior to the collection of measurement data.

Abstract: An improvement that enhances the functioning and efficiency of hay rakes or hay forks of the type used in the cleaning of horse stables and the like, includes a wall assembly having a rear wall element and two spaced-apart side wall elements extending from the rear wall element, that are positioned relative to a hay fork of conventional design so as to restrict unintended transverse displacement of hay/manure mixtures over the rear and lateral peripheral edges of the hay fork. The bottom edge of the rear wall element has a U-shaped indentation formed therein and further includes a mounting flange of U-shaped cross section aligned with and extending from the indentation for straddling the handle of a conventional hay fork so that the wall assembly is retained and positioned properly relative to the fork portion of the hay fork. The rear wall element and the side wall elements are formed with interlocking rails and slots so that the side wall elements may be readily attached to and detached from the rear wall element by a sliding motion. An opening through the mounting flange receives a fastener to secure the wall assembly to the handle of a hay fork. A resilient latch near the forward end of each side wall is capable of engaging a tine of a hay fork to further secure the wall assembly to the fork. The wall assembly may be provided entirely independently of a hay fork for attachment to an existing fork structure, or it may be integral with the fork structure.
