IPC: A61B17/322
Filed: 2001-10-15
Abstract: An improved method and apparatus is provided as a system to deliver a composition, preferably a medical or pharmaceutical composition or active, through the stratum corneum of skin, without introducing bleeding or damage to tissue, and absent pain or other trauma. The dimensions and shapes of the microelements are controlled so as to control the penetration depth into the skin. The microelements can be “hollow” such that passageways are created therethrough to allow the composition to flow from a chamber, through the microelements, and into the skin. Alternatively, the microelements can be “solid,” and the composition is applied directly to the skin just before or just after the microelements are applied to the skin surface to create the openings in the stratum corneum.

IPC: G11C7/10
Filed: 2002-02-01
Abstract: The read latency of a plurality of memory devices in a high speed synchronous memory subsystem is equalized through the use of at least one flag signal. The flag signal has equivalent signal propagation characteristics read clock signal, thereby automatically compensating for the effect of signal propagation. After detecting the flag signal, a memory device will begin outputting data associated with a previously received read command in a predetermined number of clock cycles. For each of the flag signal, the memory controller, at system initialization, determines the required delay between issuing a read command and issuing the flag signal to equalize the system read latencies. The delay(s) are then applied to read transactions during regular operation of the memory system.
