Abstract:
A method for creating spatially resolved audio signals for a listener (18) that are representative of one or more callers (12, 14, 16). A digital data signal (13) that represents an individual caller's voice (12) contains an embedded tag (24) that is identifiable with the caller. The digital data signal is transmitted from a sending device at the caller's location to a receiving device (30) at the listener's location. At the receiving device, the tag is used to associate the digital data signal with a head related transfer function (32) that is resident preferably in a lookup table of the receiving device. The digital data stream is then convolved (34) with the associated head related transfer function to form a binaural digital signal that is ported to two or more acoustic transducers (36) to create analog audio signals that appear to emanate from different spatial locations around the listener.
Abstract:
Board delamination during the singulation from a board panel and board sagging during front-end assembly are two of the biggest problems encountered in cellular manufacturing lines. The method and circuit board panel (600) of the present invention substantially eliminate assembly-line delamination and sagging for circuit board manufacturing. A number of slots are punched to fit into a circuit board profile. V-grooves (606, 608) are cut along each of the circuit board profiles through the slots and directly opposite on a top and bottom of the circuit board. Thus, optimization of the cut-outs (604) and v-groove (606, 608) configurations tearing, delamination are eliminated, and sagging is substantially reduced.
Abstract:
The present invention provides a method (1100) and circuit board panel (800) for substantially eliminating assembly-line delamination and sagging for complex circuit board manufacturing. The method includes: A) cutting/routing at least two apertures to fit into a circuit board profile, wherein a total length of the apertures is determined in accordance with a predetermined scheme (1102); and B) cutting/routing a channel/gouge on a top of the circuit board and another channel/gouge on a bottom of the circuit board along the circuit board profile through the apertures in accordance with a break-away scheme (1104). The channel/gouges are positioned at a predetermined horizontal critical distance apart with a predetermined vertical critical distance between a deepest cut edge of the channel/gouge on the top of the circuit board and a deepest cut edge of the channel/gouge on the bottom of the circuit board.

Board delamination during the singulation from a board panel and board sagging during front-end assembly are two biggest problems encountered in cellular manufacturing lines. The method (700) and circuit board panel (600) of the present invention substantially eliminate assembly-line delamination and sagging for circuit board manufacturing. A number of slots are punched to fit into a circuit board profile. V-grooves are cut along each of the circuit board profiles through the slots and directly opposite on a top and bottom of the circuit board. Thus, optimization of the cut-outs and v-groove configurations tearing, delamination are eliminated, and sagging is substantially reduced.
