    摘要: Methods of operating a memory device and memory devices are provided. For example, a method of operating a memory array is provided that includes a synchronous path and an asynchronous path. A Write-with-Autoprecharge signal is provided to the synchronous path, and various bank address signals are provided to the asynchronous path. In another embodiment, the initiation of the bank address signals may be provided asynchronously to the assertion of the Write-with-Autoprecharge signal.

    摘要: Systems and methods involve generating a baseband signal, up-converting the baseband signal to a radar signal frequency, filtering a lower sideband of the up-converted signal, and transmitting the filtered up-converted signal. Systems and methods also involve receiving a return signal, down-converting the return signal using a signal having a frequency offset from the up-converted signal, filtering the upper sideband of the down-converted return signal, and producing a baseband return signal.

    摘要: An obstacle avoidance system for obstacle detection in an opaque material. The system includes at least one electromagnetic signal source adapted to produce an electromagnetic source signal suitable for transmission through the opaque material, at least one electromagnetic signal detector adapted to receive reflected electromagnetic energy signals from discontinuities in the opaque material encountered by the electromagnetic source signal, and a reflected electromagnetic energy signal processor suitable for determining a presence of obstructions and/or strata variations within the opaque material. The system is preferably integral with a head element suitable for traversing the opaque material, for example a subterranean drill bit.
