Abstract: A method of ultrasound imaging includes a) performing a pulse-echo acquisition to produce channel signals using ultrasound transducers; b) processing transmitted and received channel signals to produce a dataset of a set of transmit elements and a set of receive elements; c) calculating an estimate of a critical imaging parameter; d) performing beamforming using the dataset and the estimate of the critical imaging parameter; e) calculating a desired loss function minimized with respect to the critical imaging parameter; f) differentiating the calculated loss function with respect to the critical imaging parameter by backpropagation; g) updating the estimate of the critical imaging parameter; h) repeating steps (d)-(g) until a convergence condition is satisfied; and i) generating an enhanced ultrasound image using the estimate of the critical imaging parameter.

Abstract: The disclosure relates to the forming and printing of paper products, particularly paper products such as self-mailers, made from a moving web of paper which is printed on a continuous forms press and folded and glue sealed in one pass through a folder. The disclosed self-mailer includes a return order envelope. The self-mailer is printed on stock of a size and thickness to conform to postal regulations with both sides of the stock being printed, perforated on press to enable tear-off of the return portion of the self-mailer, scored to enable folding, and provided with a mailing window as a continuous form. Laser printing is used for subsequent application of an individual's name and address.

Abstract: A method and apparatus are disclosed for forming printed paper products having a folded or pocket portion, for example inserts for magazines and brochures having a reply envelope. A moving web of paper from which the inserts are made is first folded along the edges thereof to form the folded or envelope portion of the insert. Thereafter, printing is carried out on the folded web. Since folding precedes printing, a web having a width which exceeds the maximum width that the printing press can accommodate may be used. In this way, an insert having a width up to the maximum width that the printing press can accommodate and/or inserts having envelope portions and/or envelope flap portions of increased size are obtained.

Abstract: A combined advertising insert and mailing envelope is formed from a single sheet which is folded so as to form a single thickness portion and a double thickness portion. The single thickness portion has a fold line which defines a flap, the fold line being coextensive with the crease lines of the pages of the magazine to position the flap and the balance of the insert, or the advertising page, on opposite sides of the saddle of a magazine. The advertising page is provided with a detachable envelope as well as with a plurality of flaps or sections on the double thickness portion which sections form windows. Each of the sections on one of the panels of the double thickness portion may be lifted to expose information printed on the other of the panels which is in registry with the window. The same insert, in some cases with slight modifications, is also suitable for insertion into perfect or adhesive bound magazines, and side-stitched magazines.
