A memory structure has a vertically oriented access transistor with an annular gate region. A transistor is fabricated such that the channel of the transistor extends outward with respect to the surface of the substrate. An annular gate is fabricated around the vertical channel such that it partially or completely surrounds the channel. A buried annular bitline may also be implemented. After the vertically oriented transistor is fabricated with the annular gate, a storage device may be fabricated over the transistor to provide a memory cell.

A radar system (100) is described including a transmitting assembly (10), a receiving assembly (20), a control unit (30) and a signal processing unit (40). The transmitting assembly (10) receives an input signal (31) and transmits an incident radar signal (2). The transmitting assembly (10) includes a Rotman lens (12) having a lens cavity (74), a plurality of beam ports (60), a plurality of array ports (62) and a patch antenna assembly (14). The lens cavity (74) has a lens gap (h) between 10 microns to 120 microns, and preferably 40 microns to 60 microns. The patch antenna assembly (14) includes a plurality of antenna arrays (130) operable to receive a plurality of time-delayed, in-phase signals from the Rotman lens (12) and to transmit the incident radar signal (2) towards a target (4). The receiving assembly (20) receives a reflected radar signal (6) and produces an output signal. The signal processing unit (40) compares the input signal (31) to the output signal and implements an algorithm determining the range, velocity and position of the target (4).

An electroosmotic pump comprises a plurality of membranes comprising one or more positive electroosmotic membranes and one or more negative electroosmotic membranes, a plurality of electrodes comprising cathodes and anodes, and a power source. Each of the positive electroosmotic membranes and negative electroosmotic membranes are disposed alternatively and wherein at least one of the cathodes is disposed on one side of one of the membranes and at least one of the anodes is disposed on other side of the membrane. At least one of the cathodes or anodes is disposed between a positive electroosmotic membrane and negative electroosmotic membrane.
