摘要:
An associated memory structure having a plurality of memories amenable for testing and a method of testing the memories is provided. First and second memories are formed, wherein data in the first memory provides a basis for at least a portion of the input to the second memory during functional operation of two memories. Preferably, an output latch for receiving the output test data from the first memory is provided. Means are provided for loading the first memory with data which is utilized as a basis for providing at least a portion of the input to the second memory. An access path from the output port of the first memory to the input port of the second memory allows use of the data in the first memory to generate at least a portion of the input to the second memory. The first memory is first tested independently of the second memory. Thereafter, the first memory is loaded with preconditioned data that is used as a basis for inputs to the second memory during testing of the second memory. The second memory is then tested by generating inputs to the first memory during testing of the second memory. Thus, outputs of the first memory constitute at least a portion of test data inputted to the second memory. A latch is provided to capture the output of the test data from the second memory.

摘要:
An impedance matching system and a network for impedance matching at a driver circuit output for high frequency input-output devices. The impedance matching network comprises an adjustable-length transmission line having a length adjusted in proportion to the magnitude of transients on the driver circuit output and an input impedance, which is purely reactive, and is a function of its length. The purpose of the adjustable-length transmission line is to reduce transient voltages by providing a matching impedance for the reactive component of the impedance of the receiver circuit to the driver circuit. In the preferred embodiment, the impedance matching network comprises two parallel conductive lines formed on the system card, shorted by a movable stub, and connected in parallel to the driver circuit. Optionally, the impedance matching network further comprises a control circuit which detects overshoots and undershoots on the driver circuit output and provides a control current proportional to the magnitude of overshoots and undershoots to an electromagnetic adjustment mechanism which provides a linear adjustment to the moveable stub proportional to the control current.

Sunvisors provided with vanity mirrors usually have the mirror, with or without illumination, fixed to the upper surface of the visor when in the stowed position, and to avoid undesirable reflections a cover is sometimes provided. Also, various switches are provided to control energization of the lighting means when present. The invention simplifies this kind of visor by arranging that the mirror is carried by a hinge (7b) near the lower margins of the visor to open out therefrom downwardly from a stowed position facing into a recess (11) in the upper surface of the visor. The lower edge of the visor may be relieved as at (12) to maximize the hingeing angle of the mirror so as to achieve compactness while satisfying visor safety requirements. The wire frame (7) of the visor may be joggled inwards at (7a) and (8a) to provide hinge pins and electrical connections (7b) and (8b) for the visor.
摘要:
The present invention provides for x-ray imaging and ultrasound imaging of a body region of interest in a spatially correlatable manner. The resultant x-ray and ultrasound images may be combinatively employed to provide three-dimensional information regarding a location of interest within the body, and is particularly apt for use in the analysis/biopsy of potential lesions and suspicious masses in a female breast. The invention provides for direct body contact by an ultrasound imaging head, as well as targeted ultrasound imaging of a selected portion of the region from which x-ray images are obtained. A user interface system facilitates various procedures including ultrasound guided needle biopsy procedures.

摘要:
An ABIST circuit for testing a memory array has a blanket write subcycle (WC), an RC.sub.3 subcycle, and an RC.sub.4 subcycle. The ABIST circuit includes a programmable pattern generator that provides eight programmable data bits, eight programmable read/write bits, and two programmable address frequency bits to determine the specific test patterns applied to the memory array. The address frequency bits determine how many memory cycles will be performed on each cell of the memory array. In X1 mode, only one memory cycle is performed on each cell during any given subcycle. In X2 mode, two memory cycles are performed on each cell, allowing a cell to be written, then subsequently read in the same subcycle, In X4 mode, four memory cycles are performed on each cell, and in Xg mode, all eight bits of read/write and data are used on each cell, resulting in eight memory cycles for each cell within the memory array.
