Abstract:
A microwave sterilizer for sterilizing a connector or coupling that interconnects a first conduit from a source of liquid to be infused into a living body to a second conduit implanted in the body. The apparatus of the invention comprises a housing having first and second members forming a guided wave structure adapted to be removably closed around the coupling or connector and further including first and second clamping means. The clamping means are adapted to clamp respective conduits and are operable to isolate a charge of the liquid within the connector. A microwave source is used to generate energy which in turn is coupled to the guided wave structure to cause heating of the liquid charge to a temperature level to cause sterilization so as to destroy substantially all form of bacteria therein. After a predetermined heating sequence, the apparatus is released and the bag side clamping means is first released so as to pass the sterilized charge of liquid into the source or bag.
Abstract:
Apparatus, system, and method including a single common node bias voltage (316); at least a first current path (310) to drive a bias current based on the single common node bias voltage (316); at least a first current mirror to mirror the bias current in a second current path (320); and an output current path (350) comprising current drivers to drive source and sink currents that are matched to the bias current. The first current mirror may include at least one partial cascode current mirror. The apparatus and system provide a single common node bias voltage (316) to generate a bias current; mirror the bias current in at least one current path; and output well-matched output source and sink currents based on the bias current.

Abstract:
An attachment assembly and method for attachment are provided. The attachment assembly includes a base (36) having a shaft (38) extending therefrom and a non-conductive compression member (28) having a plurality of slots (52) and configured to engage the shaft (38). The attachment assembly further includes a locking component (22) configured to engage the shaft (38). The locking component (22) has a plurality of resilient extensions (24) configured to engage the plurality of slots (52) of the compression member. The locking component (22) is configured to compress the compression member (28) in a tightened state and wherein the resilient extensions (24) form a conductive path when in the tightened state.
Abstract:
A connection arrangement for a micro lead frame plastic (MLP) package (20) is provided that includes a paddle (28) configured to be connected to a circuit board (24) and a first ground pad (26) and a second ground pad (26) each connected to the paddle (28). The first and second ground pads (26, 26) together with the paddle (28) are configured to provide continuity of ground between the circuit board (24) and a chip (40) mounted to the paddle (28).
Abstract:
A dielectric resonator radiator (100) comprises first and second portions (101, 103). Each portion is conical or monotonically varying in shape and has a larger basal surface (105, 107) and a smaller basal surface (109, 111) and defines a longitudinal axis (121). The first and second portions are arranged with their longitudinal axes collinear and their larger basal surfaces (105, 107) parallel and adjacent to each other and separated by a gap (113).
Abstract:
A dielectric resonator circuit (500) and dielectric resonators (510) included therein. Each resonator (510) includes a first axial body portion (510a) separated from a second axial body portion (510b) by a gap which interrupts the continuity of dielectric material constituting body portions (510a, 510b) and which gap may comprise material such as a plastic insert (510c) having a dielectric constant smaller than that of material comprising the body portions (510a,510b). One or both of the body portions may have a conical part and part of adjacent resonators may laterally overlap each other.
Abstract:
A system, apparatus, method and article to emulate a filter using digital elements are described. The apparatus may include a digital-to-analog converter (110, 500) having an impulse response emulator (202, 510), the impulse response emulator (202, 510) to receive multiple digital signals each having a predetermined waveform, and convert a sequence of bits from each digital signal to a predetermined analog waveform corresponding to the sequence of bits. In preferred embodiments, the sequence of bits can be converted using a lookup table (506) or a digital filter (704).
