Methods systems and system components for optimizing contrast resolution of an imaging or sensing system utilizing multiple channels of broadband data associated with an array of transducers. Channels or data are filtered by passing the channels of data through finite impulse response (FIR) filters on each channel. The filters each have multiple taps having tap weights pre-calculated as a function of distance of the array from an object that energy is being transmitted to or reflected from. The weights are pre-computed through a deterministic equation based on an a priori system model.

The present invention provides an apparatus and method for producing substantially clear ice in a variety of desired shapes. An insulated ice mold form containing one or more mold cells is suspended over a liquid water reservoir contained in an insulated container. Each ice mold cell is exposed to freezing air resulting in the formation of ice in each mold cell with ice formation progressing from the top to the bottom of each ice mold cell. A liquid water reservoir below each ice mold cell serves as an impurity sink into which impurities and gases are driven as ice crystals form in each ice mold cell and as a heat sink to substantially arrest ice shape growth beyond the bottom of each ice mold cell at or near the ice-reservoir water interface.

A packaging device for protectively enclosing an optical component in a substantially clean and anhydrous environment without imparting undue mechanical stresses on the optical component and adjacent segments of optical fiber coupled thereto. An intermediate component is used in combination with a sealing material for sealing the fiber aperture of a protective housing while allowing an optical fiber to extend therethrough. The protective housing is made out of a material having a coefficient of thermal expansion that closely matches that of the optical fiber. A chain of material CTE that includes the CTE of the intermediate component is used in order to circumvent the need for a sealing material having a high melting temperature. The packaging device is also designed so as to reduce water ingress by optimizing the configuration of the sealing component and adjacent structures.

A control system for a linear feed-forward amplifier, using the ratio of measured spurious energy. Measuring receivers are coupled to two monitoring points to measure the spurious energy content in the error signal and at the main output of a feed-forward amplifier. The control system measures the ratio of these detected spurious, and uses this to optimize the settings of the second loop distortion cancellation. With the addition of an extra monitoring point, the same technique may also be used to control an adaptive predistorter prior to the main amplifier.

The amount of disturbance in mark area is reduced by restricting the range of the area of a subsequent mark that is to appear.
