摘要： A test clocking scheme that separates the clock driving the functional logic and the memory from the clock driving the test logic and the memory. In other words, the test clocking scheme separates the memory functional clock from the memory test clock into two clock paths. The test clocking scheme provides for the ability to separately shut off either the memory functional clock source or the memory test clock source, provides that less power is required during production testing, and provides that simulation time is reduced during design verification because the functional logic is not clocked.

摘要： An expandable medical device includes a plurality of elongated struts, forming a substantially cylindrical device which is expandable from a first diameter to a second diameter. A plurality of different beneficial agents may be loaded into different openings within the struts for delivery to the tissue. For treatment of conditions such as restenosis, different agents are loaded into different openings in the device to address different biological processes involved in restenosis and are delivered at different release kinetics matched to the biological process treated. The different agents may also be used to address different diseases from the same drug delivery device. In addition, anti-thrombotic agents may be affixed to at least a portion of the surfaces of the medical device for the prevention of sub-acute thrombosis. To ensure that the different agents remain affixed to the device as well as to each other, masking and de-masking processes may be utilized.

摘要： A monolithic microwave oscillator using a negative resistance cell includes a resonator, a negative resistance cell that employs an active device, an output buffer for voltage and current amplification, and a field effect transistor. The negative resistance cell includes a bipolar junction transistor as its active device, with the output buffer circuit coupled to a base of the BJT through the field effect transistor. The combination of the resonator and the negative resistance cell produce a periodic RF microwave signal that is sampled, amplified and buffered by the buffer circuit without degradation.
