The Magnetek patent solves the following problem:

This creation relates generally to small, inexpensive electrical connectors; and especially in high-volume manufacturing half of connectors that mate with another half connectors and contact pins in pretty rough construction. The rough-construction pins most favorable for making ballast fluorescent connection. luminaires.

Our analysis of this patent is as follows:

Magnetek’s patent US 5350292 A deals with Electrical half connector with contact-centering vanes.
This precious, little half connector includes at least one electrical terminal (usually a woman who contacts). The half-connector body defines a hole to receive each terminal. Each terminal has at least one retaining element for participation in half-connector (eg, a springy tang snaps behind an internal flange) to have terminal half connector. Each hole has a portion of relatively large transverse dimension to receive his terminal, generally with transverse clearance of the circumference of the terminal. Each hole also has a part in reducing the transverse dimension of the receiving terminal and seek to have (the) elements in the terminal to retain the terminal. Each hole has several integral part – in other words, some structural elements () integral with the body of the half-connector – for focusing on the terminal in the large part of the hole. Preferably the essential element includes at least two and preferably three radially inward-extending protruding from an inner wall of the large part of the hole. Each one of these is better very thin, ideally about 0.2 to 0.23 millimeter thick.

Method and apparatus for unevenly encoding error images

The Intel Corporation patent solves the following problem:

An important part of most of the methods for compressing sequences of digital video images is the motion analysis. In typical motion analysis, a target image in a sequence of images divided into a plurality of blocks of pixels. A target in the region containing at least one pixel block is selected from the target image. The image before the target image analyzes to find a region in the first image that closely correspond to the target region in the target image. Block matching techniques based on low-square-error or mean-perfect-mistakes often used to find the region in the first image that closely correspond to the target region in the target image. If no motion occurred, the main target regions have the same coordinates in the frame image. The motion came in the first region to offset or translated relative to the target region by an amount that represents a displacement vector. This process is usually repeated for each target region in the target image, thus yielding a displacement vector for each target region. These eviction vector after that used in a previous reconstructed image to form a predicted image. A false image made from the difference (remaining errors) between the target image and the predicted image. The displacement vector and the wrong image is then encoded for the subsequent use of a decoder for decoding the compressed digital video signal. A known motion compensation system described in US Pat. No. 5,134,478 Golin, entitled "Method and apparatus for compressing and decompressing a Digital Video Signal Using Error foretold Images", the contents of which are included here by reference.

Our analysis of this patent is as follows:

Intel Corporation’s patent US 5347311 A deals with Method and apparatus for unevenly encoding error images.
A method and apparatus for encoding partially in a picture. The picture is divided into a plurality of blocks and a block selected for processing. A boundary lying along the selected block associated with a cal also selected. The errors associated with the selected block decline unevenly through a reduction that increases the degree of false decrease as the distance between the fault and increasing border. The selected block is encoded as reduced errors.

The Seikosha Co., Ltd. patent solves the following problem:

In the past, even in one of the following two methods are mainly used to identify the center position of a reference mark formed on a printed circuit board, to give a standard position for machining, when a printed circuit board is machined.

Our analysis of this patent is as follows:

Seikosha Co., Ltd.’s patent US 5347462 A deals with Method for machining printed circuit board.
To be able to resolve a central accurately and automatically, a reference mark on a printed circuit board is held to determine transition points tone, so as to determine an interim center and diameter to score on a four-point seeking ways. Next, a preset minute value is added to the interim diameter marks to determine a pattern of circular diameter, so a standard circle with interim center as its center. Then, image processing is performed to that standard circle and the label parted into a plurality of sections. The center marks detected by determining the center section of the tone that showed the mark. Machining operations such as perforations being carried out on the basis of observed center.

The Trimble Navigation Limited patent solves the following problem:

The invention relates generally to antenna pointing system, and more specifically the use of the elements in global positioning system (GPS) to provide azimuth and elevation information to a directional antenna can be quickly and accurately taught his intended target location.

Our analysis of this patent is as follows:

Trimble Navigation Limited’s patent US 5347286 A deals with Automatic antenna pointing system based on global positioning system (GPS) attitude information.
A picture of the present invention is a system for automatically pointing a directional antenna. The system consists of two GPS antennas mounted horizontally opposed ends of the antenna direction, the placement is such that the GPS antenna lie in a line with a normal vector approximately parallel to a boresight direction antenna. The outputs from the GPS antenna is downconverted to a measure frequency and differentially phase compared to each of a plurality of radio GPS satellites. A measure controller received about comparisons. A navigation computer receives measurements from the controller measure and uses a microprocessor to calculate the GPS latitude and longitude and the attitude angle to pair the GPS antenna. A servo antenna pointed in the direction of a particular target communication satellite, based on the computed azimuth, elevation, latitude, and longitude, as given by the navigation computer. One of these servos used to move the GPS antenna roughly in a circle averaged multipath effects to improve accuracy and reduce the integer doubt.
