An optical positional information detection apparatus for detecting a position indicated by a pointer on a display surface. The optical positional information detection apparatus includes an imaging unit that captures an image of one or more pointers situated within a predetermined distance from the display surface; an image obtaining unit that obtains a first image captured by the imaging unit and a second image captured by the imaging unit; a movement distance calculation unit that uses a first feature amount based on the first image in which first pointers are captured and a second feature amount based on the second image in which second pointers are captured so that the movement distance calculation unit calculates a movement distance from the first pointers to the second pointers; and an association unit that associates the second pointers with the first pointers based on a limitation on the movement distance.

Optical positional information detection apparatus and object association method

A document processing system is disclosed that is capable of processing both fixed-format and unfixed-format hand written paper documents. The document processing system includes an encoding unit that encodes a sheet ID for identifying a hand written first document on a sheet to generate a coded sheet ID; a decoding unit that decodes the coded sheet ID; a document-sheet ID association unit that associates the sheet ID with a document ID assigned to a computerized second document; a printing unit that acquires the sheet ID and prints the coded sheet ID on the first document; a sheet ID management unit that manages the sheet ID; an information acquisition unit that acquires the sheet ID decoded by the decoding unit, and hand-written data from the first document on which the coded sheet ID is printed; and a process-sheet ID association unit that associates the sheet ID with a process ID of a process for processing the hand-written data acquired by the information acquisition unit.

Electrical connector

Frame grounding fixtures (plug connector fixtures) are provided at the longitudinal ends of the plug housing for mounting the plug connector half on a printed circuit board K , and receptacle connector fixtures are provided at the longitudinal ends of the receptacle housing for mounting the receptacle connector half on a printed circuit board K . When the plug and receptacle connector halves and are intermated, the frame grounding fixtures are brought into contact with the receptacle connector fixtures because the contact surfaces of the frame grounding fixtures are provided in the same planes as the inner surfaces of the plug housing , and the contact surfaces of the receptacle connector fixtures are provided in the same plane as the outer surfaces of the receptacle housing

A plug connector,includes a central grounding plate,which is provided between two lateral rows of signal plug contacts,. In these rows, grounding plug contacts,are positioned to partition the signal plug contacts,and to establish electrical contact with the central grounding plate,. A receptacle connector,includes a pair of lateral grounding plates,, which are positioned outside two lateral rows of signal receptacle contacts,. Grounding receptacle contacts,are provided at locations which correspond with the locations of the grounding plug contacts,and are in electrical connection to the lateral grounding plates,This electrical connector assembly has a relatively small number of parts yet prevents crosstalk and reflection of signals effectively.

A contact 60 has a 'T'-like cross section, in which the width W3 of a back face or back portion 61d is greater than the width W4 of a front face or main section 61f. A contact-retaining groove 54 has a trapezoidal cross section, in which the width W1 of a bottom of the contact-retaining groove is greater than the width W2 of an opening on a lateral face of a contact-retaining portion 52. Also, the width W2 of the opening of the contact-retaining groove is smaller than the width W3 of the back portion 61d of the contact. When the contact 60 is received and retained in the contact-retaining groove 54, at least the back portion 61d of the contact 60 is retained inside the contact-retaining groove 54.

Electrical connector with contacts retained in housing grooves

A plug connector 1 and a receptacle connector 5 are provided with two poles of power plug contacts 30, 30 and power receptacle contacts 70, 70, respectively, at end portions of their housings 10 and 50 on the right and left sides of signal contacts 20, 60, and 60'. The right and left end portions of the housings 10 and 50 are provided with connector securing metal parts 40 and 80 made of a conductive material, which cover the power contacts 30 and 70, respectively, whereby the connectors can be attached to circuit boards. When both connectors 1 and 5 mate together, the connector securing metal parts 40 and 80, the power contacts 30 and 70, the contacts 60, 60', and 20 are successively connected to each other.

Electrical connector with shielded power contacts

An electrical connector assembly comprises a plug connector half 1 and receptacle connector halves 5 and 9, including a receptacle connector half 5 with power transmission contacts and a receptacle connector half 9 without any power transmission contact. These receptacle connector halves are alternatively used in correspondence with the application. The receptacle connector half 5 with power transmission contacts is provided with two polar receptacle contacts 70 for power transmission in a receptacle housing 50. These receptacle contacts 70 for power transmission are brought into contact with plug contacts 30 for power transmission when the plug connector half 1 and the receptacle connector half 5 are intermated. On the other hand, the receptacle connector half 9 without any power transmission contacts is provided with accommodation spaces 57 in a receptacle housing 50'. These accommodation spaces accommodate said plug contacts 30 for power transmission when the plug connector half 1 and the receptacle connector half 9 are intermated.
