Title: A method and system for redeeming coins and transferring the value to an EPOS system
Inventor: HALLOWELL CURTIS W
IPC: G06Q20/00
Filed: 2009-03-18
Abstract: A method of redeeming coins using a self-service coin redemption machine is provided and includes the act of printing on a blank substrate, using a self-service coin redemption machine printer, indicia associated with a coin processing transaction before or during the processing of a batch of coins in the self-service coin redemption machine. The method also includes the acts of dispensing the substrate, processing a batch of coins in the self-service coin redemption machine to determine a redemption value thereof, and transmitting the redemption value from the self-service coin redemption machine to an EPOS terminal using a communication device. The method further includes inputting the indicia printed on the substrate into the EPOS terminal using a data input device, verifying, using the EPOS terminal, that the indicia input into the EPOS terminal corresponds to an open transaction. Preferably, the value associated with the printed substrate (voucher) can be exchanged for cash, merchandise or other services at the EPOS terminal and the transaction can then be closed. The indicia can be a random number or a user-inputted string. Instead of using a printed voucher, the value of the coin processing transaction can be associated with a user account after the user has been identified at the coin redemption machine. The substrate could also comprise a RF tag which is read by a RF tag reading device at the point of sale terminal.

Title: Halftone image processing for reduced dot gain and patterning
Inventor: CAVE ANDREW WILLIAM PETER
IPC: H04N1/405
Filed: 2009-09-11
Abstract: A computer program and method of, generating 1-bit (halftone) image data from multiple-bit (continuous) image data, includes the comprises the steps of receiving multiple-bit image data comprising multiple-bit pixel values and deriving from the multiple-bit pixel values image data comprising "on" and "off" pixel values. Each pixel value of the halftone image data corresponds to a pixel of an output medium, which an output device would attempt to mark when printing the halftone image data if the pixel value were "on". When printed, the halftone image data produces an image constituted by dots, each dot corresponding to a plurality of pixel values of the halftone image data, the pixel values corresponding to a block of M*N horizontally and/or vertically adjacent pixels of an output medium. At least one of M and N is greater than one. For at least some of the dots, where M or N is equal to one (ie where the pixels represent a line), a pixel value corresponding to a first or last pixel of a row of horizontally adjacent pixels, or to a first or last pixel of a column of vertically adjacent pixels, is "off'. Where both M and N are greater than one (ie for a 2D array of pixels), at least one pixel value corresponding to a pixel of a first or last row of horizontally adjacent pixels is "off' and/or at least one pixel value corresponding to a pixel of a first or last column of vertically adjacent pixels is "off'. By selectively adjusting the halftone patterns unwanted dot gain and patterning are reduced.

Title: Sash for windows and doors with attachable and detachable rails
Inventor: YOO JUNG SIK
IPC: E06B3/46
Filed: 2009-09-29
Abstract: There is provided a window and door frame for doors and windows built in a wall of a building. The window and door frame includes an extruded frame member. One face of the frame member is formed along a length direction thereof with a rail insertion groove. The window and door frame further includes a rail structure adapted to be combined with the rail insertion groove. The rail insertion groove is formed with engagement grooves, while the rail structure is formed with engagement projections. The rail structure is easily combined to and removed from the frame member by means of engagement between the engagement projections and the engagement grooves. Since the rail structure is attachable and detachable, a heavier door can be conveniently installed and the window and door frame can be easily cleaned up. Further, only a damaged rail structure can be replaced.

IPC: B23G5/12
Filed: 1917-07-14
Abstract: 117,484. Lavender, H. P. July 14, 1917. Screwing dies and die heads.- Screwing-dies are opened automatically when relative movement of the work and the die support is stopped. The support A, Fig. 3, is carried in a lathe turret &c. by means of a shank 1 and carries the axially movable holder B by means of a shank 2 and pin 4. The dies 8, 9 slide in slots in the holder B and are closed bv a cam 13 rotated by a handle 23 until a projection 24, Fig. 4, passes a stop 26 behind which it falls, as shown in Fig. 4, owing to the action of springs 36, 37 moving the holder B axially. The stop 26 is adjusted, to vary the space between the dies, by a wheel 27 and worm 30 with a graduated head 32, and is locked by a nut 34. When the length required has been screwed, the movement of the support A is arrested but, owing to the action of the dies, the holder B still advances until the projection 24 is released from the stop 26 and springs 22 open the dies 8, 9 and return the handle 23 &c. to their original position, as shown in Fig. 7. To make a rough and finishing cut without adjusting the stop 26 the projection 24 is carried by a slide 39, Fig. 4, moved by an eccentric 41. The springs 22 are attached to pins 54 which can be withdrawn by hand to allow the die 8 to be removed for grinding, renewing, &c., or by pressing the springs 36, 37 off the ends of the pin 20 the holder B can be removed as a whole. If both sets of springs are detached, the dies 8, 9 with the side plates 18, 19 can be removed.
