Abstract: Register banks are used to allow for fast beam switching in a phased array system. Each beam forming channel is associated with a register bank containing M register sets for configuring such things as gain/amplitude and phase parameters of the beam forming channel. The register banks for all beam forming channels can be pre-programmed and then fast beam switching circuitry allows all beam forming channels across the array to be switched to use the same register set from its corresponding register bank at substantially the same time, thereby allowing the phased array system to be quickly switched between various beam patterns and orientations. Active power control circuitry may be used to control the amount of electrical power provided to or consumed by one or more individual beam forming channels such as to reduce DC power consumption of the array and/or to selectively change the effective directivity of the array.

Abstract: An ergonomic desk includes adjustable legs for supporting a primary desk section, which in turn has a primary desk surface. A second desk section includes a second desk surface for supporting an input device such as a keyboard and a mouse. In addition, the ergonomic desk includes arm support sections. The ergonomic desk supports the weight of the user's arms while correctly positioning the user to relax nerve bundles in the neck and upper back area. In addition, the ergonomic desk may be adjusted and sized to people of varying proportions.
