US Patent:

RE40691, Mar 31, 2009

Filed:

Jun 17, 1999

Appl. No.:

09/335376

Inventors:

Jae S. Lim - Winchester MA, US

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

G10L 19/02

US Classification:

704206, 7042001, 704224, 704E19019, 704203

Abstract:

An audio type signal is encoded. The signal is first divided into bands. For each band, a yardstick signal element is selected. The yardstick may be the signal element having the largest magnitude in the band, the second largest, closest to the median magnitude, or having some other selected magnitude. This magnitude is used for various purposes, including assigning bits to the different bands, and for establishing reconstruction levels within a band. The magnitude of non yardstick signal elements is also quantized. The encoded signal is also decoded. Apparatus for both encoding and decoding are also disclosed. The location of the yardstick element within its band may also be recorded and encoded, and used for efficiently allocating bits to non-yardstick signal elements. Split bands may be established, such that each split band includes a yardstick signal element and each full band includes a major and a minor yardstick signal element.

Appl. No.:

12/346247

Inventors:

Jae S. Lim - Winchester MA, US

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

H04N 5/262

US Classification:

34824099, 348345, 348 E5045, 382154, 382276, 382285

Abstract:

Processing images of a scene taken with different focus includes, for each of at least some of the images, determining at least one portion of the image having a predetermined characteristic. A representation of the scene is generated that includes an array of elements, where each of at least some of the elements corresponds to a determined portion of at least one of the images. An element of the array is based on a correspondence between a distance associated with a determined portion of at least one image and a focused distance associated with at least one image. The generated representation is stored or provided as output.

International Classification:

H04N 19/00072
H04N 7/12

US Classification:

3752402

Abstract:

Encoding data includes: computing a first set of coefficients based on a plurality of transforms each computed over a different portion of an array of data, and a second set of coefficients based on a transform computed over the array of data; choosing a set of coefficients to represent the array of data from a group of multiple sets of coefficients, the group including the first set of coefficients and the second set of coefficients; and encoding the chosen coefficients and one or more parameters related to the chosen coefficients.

Inventors:

Jae Lim - Winchester MA, US

International Classification:

H04N 11/04

US Classification:

375240110, 375240180

Abstract:

A method of encoding a sequence of video frames, comprising receiving a sequence of video frames, encoding at least a first portion of the sequence of frames using the first type of transform/subband representation to produce first transform/subband coefficients, encoding at least a second portion of the sequence of frames using the second type of transform/subband representation to produce second transform/subband coefficients; and providing the first and second transform/subband coefficients at an output.

Appl. No.:

13/442052

Inventors:

JAE HYUN LIM - CRESSKILL NJ, US

International Classification:

H02K 13/00

US Classification:

290 50

Abstract:

Disclosed is a method to create an extra electric energy source to power electric batteries while the electric bicycle is in motion. This electric energy source is generated from a separate installed component (a specially designed generator). This component converts the rotational energy from a shaft connected to the wheel through a delivery device.
