摘要:
A system of the invention connects an Asynchronous Transfer Mode (ATM) data network to a plurality of host units. The data network transfers data in the form of ATM cells. A plurality of ATM termination units are connected between the network and the host units respectively. Each termination unit includes a virtual channel memory for storing ATM cells; a processor for segmenting and reassembling the ATM cells stored in the memory; a network interface for transferring ATM cells including segmented Conversion Sublayer Payload Data Units (CS-PDU)s between the memory, the processor and an ATM network; and a host interface for transferring unsegmented CS-PDUs between the memory, the processor and a host unit. The processor of each termination unit includes a computing unit, and a programmable instruction memory for storing a program for controlling the computing unit. The system further includes an Advanced Programmable Interrupt Controller (APIC) system for distributing interrupts from the network to the host units. The APIC system includes a plurality of local units for prioritizing and passing interrupts to the termination units respectively; and an Input/Output (I/O) unit for receiving interrupts from the network, determining to which host units interrupts are addressed, and feeding interrupts to local units corresponding to host units to which interrupts are addressed. Termination units and corresponding APIC local units may be formed on a single integrated circuit chip, and the chip may include ATM I/O units and/or processors constituting the host.

Disclosed are systems and methods of producing electronic devices. These electronic devices include excess circuits to be used as replacements for circuits that are found to be defective within the electronic device. The excess circuits are included in a different device component than the circuits that are found to be defective. The replacement process occurs after the excess circuits and defective circuits are included in an electronic device including the different device components. Identification of the defective circuits may occur before or after the defective circuits are incorporated in the electronic device. In some embodiments, systems and methods of the invention result in improved manufacturing yields as compared with the prior art.

Techniques are disclosed for performing color registration estimation and correction in a multi-head printer. A registration target is printed by the printer and captured by an image capture device (such as a camera) within the printer. The registration target includes a plurality of shapes, each of which is printed by a single one of the print heads in the printer, and which are arranged in a pattern designed to enable cross-web and down-web registration estimates to be generated. The printer analyzes the captured target to generate such cross-web and down-web registration estimates and thereby to generate cross-web and down-web registration corrections. The printer applies the registration corrections to subsequent print jobs, thereby reducing or eliminating misregistration in printed output. The techniques disclosed herein are suitable for use in printers having print heads that differ in resolution from each other.

The invention provides for a method of making more than one punchout from a single dried blood spot. The method comprising the steps of making a first punch and sequentially making at least a second punch in the dried blood spot. The second punch comprises boundaries which are at least partly outside of the boundaries of the first punch. The surface areas of the first punch and second punch are together equivalent to the minimum surface area required for testing of the dried blood spot.
