Infinite-impulse response (IIR) filters are one of the primary types of digital filters in digital signal processing (DSP) systems. Among many different IIR filters, a single-pole low-pass may be the most widely used filter in various applications. © 2010 IEEE.

An electrical interconnect has a non-planar ceramic substrate with opposing first and second ends. A first conductive layer having first and second opposing sides is disposed within the ceramic substrate with one of the first and second opposing sides exposed at the first end and one of the first and second opposing sides exposed at the second end. The electrical interconnect is useful to join an integrated circuit in a hybrid package to a circuit board in high frequency communication applications.

A wet mate electrical connector includes a female connector and a male connector. The female connector can include a female connector body defining a central passage. The central passage can include a plurality of female contacts. The male connector can include a male connector body defining a central passage. A male pin can project from the central passage of the male connector body. The male pin can include a plurality of male contacts and be insertible into the central passage of the female connector. The male connector can also include a sleeve slidably displaceable over the male pin between a first position in which the sleeve covers the plurality of male contacts in a protected condition, and a second position in which the sleeve is retracted and exposes the plurality of male contacts.

Apparatus and methods to reduce unwanted motion in a payload of a precision instrument are described. The payload may be supported by an intermediate mass. A feedback signal based upon sensed motion of the intermediate mass may be applied to an intermediate-mass actuator arranged to drive the intermediate mass. Additionally, a feedforward signal may be applied to a payload actuator arranged to drive the payload and used to suppress unwanted motion of the payload. The feedforward signal may be derived from a source within the apparatus or external to the apparatus that would otherwise cause unwanted motion of the payload.
