  • Patent number: 6808102
    Abstract: Wedge wire bonding apparatus are disclosed with an improved configuration in which the transducer axis lies on a line that bisects the XY axes, and the operator views the bonding process by looking directly along the axis of the transducer. The result is a shorter bonding cycle time as time is saved as the bonding head moves from a first to a second bonding position while at the same time the operator is placed in the best possible position for viewing the bonding operation, which facilitates in particular any necessary alignment and set-up steps.

  • Patent number: 6804892
    Abstract: An alignment device provides one or more references, such as laser lines and planes in horizontal and vertical orientations. One version of the alignment device includes an optics mounting assembly situated in a pivot socket on a frame to provide an output beam. Multiple spring systems and one or more alignment assemblies align and secure the optics mounting assembly in the socket. As a result, the output beam has a desired orientation with respect to true level. A first spring system directs the optics mounting assembly through the pivot socket. A second spring system holds the optics mounting assembly in communication with the alignment assemblies to reduce system backlash. One implementation of the pivot socket has a surface in the form of a sphere's interior surface. A set of support members on the optics mounting assembly rest on the pivot socket's spherical surface—causing the output reference beam to extend from the center of a sphere including the socket's spherical surface.

  • Patent number: 6466997
    Abstract: A method and system for requesting an interrupt from a host system to service an adapter connected to the host system and a data interface. Data packets, including one or more data cells, are transferred between the data interface and the host system. The host system includes a host memory that includes a plurality of memory slots to store data packets transferred between the data interface and the host system. It is determined when a transfer of data has resulted in an occurrence of an interrupt event. An interrupt event occurs when the transfer of data includes a transfer of a data cell between the data interface and the host system and the data cell is defined to be an end of a data packet. In response to the occurrence of an interrupt event, it is determined whether to generate an interrupt request to the host system.

  • Patent number: 6337851
    Abstract: A method of scheduling a plurality of data flows in a shared resource in a computer system, each of the data flows containing a plurality of data cells including the steps of providing a scheduler in the shared resource, initializing the scheduler to receive the plurality of data flows, receiving a first data flow in the scheduler, said first data flow having a first flow rate, receiving a second data flow in the scheduler, said second data flow having a second flow rate, scheduling, by the scheduler, the first data flow and the second data flow such that the first flow rate and the second flow rate are less than an available bandwidth in the shared resource and a relative error is minimized between an actual scheduling time and an ideal scheduling time on a per cell basis, and repeating the steps of receiving and scheduling.

  • Patent number: 6212567
    Abstract: A mechanism for mitigating the rate at which status reports associated with raw cell data transfers occur during receive operations in a network node is presented. The network node has an adapter for coupling a network and a host system, the host system including a host memory. The adapter operates to reassemble cell data received from the network and store the reassembled cell data in the host memory. A raw report holdoff counter is programmed to count a number corresponding to a preselected rx raw report holdoff value. If a raw cell data transfer request to be processed is detected, rx raw report information necessary to creating an rx raw cell status report is copied to a temporary storage area. When the data is transferred to the host system, the raw report holdoff counter is modified by one. When the modified counter has expired, the rx raw report information is written to a report queue in host memory.

  • Patent number: 6167394
    Abstract: A computer-based document management system that utilizes a geographic interface and allows any interested party to view individually selected location-specific documents which are stored in a particular geographic location from anywhere in the world is disclosed. Examples of the site-specific documents include, for example, MSDS information. Access to this electronically stored information may be had via any suitable medium such as, for example, the internet, the world wide web, an intranet, or a local area network.

  • Patent number: 6115775
    Abstract: A time-based and event-based interrupt frequency mitigation scheme is provided. A holdoff event counter is programmed to count a holdoff event count corresponding to a number of interrupts. A holdoff timer is programmed to time a holdoff interval representing the time period to elapse before the generation of an interrupt request to the host system can occur. When a data transfer request associated with the transfer of data from or to the host system is serviced and results in the occurrence of an interrupt event, the holdoff event counter is modified by one. If either the holdoff event counter or the holdoff timer has expired and the interrupt is enabled, an interrupt request to the host system is generated. In response to such interrupt request generation, the interrupt is processed and both the holdoff event counter and the holdoff timer retriggered.

  • Patent number: 6067563
    Abstract: A mechanism for avoiding an initiation of control read transactions on a system bus coupling a host system having a host memory and an interface connected to a peripheral unit as data is moved between the host system and the peripheral unit is presented. Control information associated with data memory portions in host memory is written to the interface for data memory portions storing outgoing data and data memory portions to receive incoming data. The interface includes a controller to move data between the host memory and the interface by first obtaining the control information for the associated data portions. The interface writes status reports in association with the movement of data between the interface and the host memory via the system bus. The mechanism thus enables data transfers to occur via the system without the initiation of control reads in absence of an exception condition.
