Abstract: A flexible hose 10 having a built-in handle 20. The hose 10 has at least three layers including a first elastomeric layer 12, a second elastomeric layer 16, and at least one reinforcing layer 14. At least one handle 20 is affixed to at least one of the respective reinforcing layers 14. The handle 20 at least partially extends radially outwardly of the external surface 18 of the hose 10. In a preferred embodiment, the handle 20 is made from flexible material.

Abstract: A method of testing high speed interconnectivity of circuit boards having components operable at a high speed system clock, employing an IEEE 1149.1 standard test method in which test data is shifted into and from the components at the rate of a test clock during Shift.sub.-- In and Shift.sub.-- Out operations, and having an Update operation and a Capture operation between the Shift.sub.-- In and Shift.sub.-- Out operations, the components including a first group of components capable of performing the Update and Capture operations at the rate of the Test Clock only and a second group of components capable of performing the Update and Capture operations at the rate of the system clock, the method comprising the steps of performing the Shift.sub.

Abstract: An interface allowing to transfer serial test data from a Test Access Port (TAP) to controllers located in several clock domains is described. The clock frequencies can be different from each other and do not need to be related in phase to each other or with the clock of the TAP. The interface is proven to work reliably as long as the clock frequencies used for the test controllers and registers is 3 times higher than the one of the TAP used to source the serial test data.

Abstract: A method of and apparatus for testing multi-port memory performs a shadow read to an adjacent memory cell concurrent with a write operation associated with typical read-write testing. In the presence of a bit wire short or a word wire short, the concurrent read of an adjacent memory cell will cause the value of that cell to be corrupted. The corrupted value is then found by the read-write testing. Consequently, the testing takes no longer than read-write testing. In addition, the testing scheme can be modified for memory with read only ports. An embodiment of the apparatus employs an exclusive OR gate on the least significant bit of the test row address line to generate the shadow read address.
