Abstract: A conformable waveguide for conveyance of high frequency radio signals including a hollow component having a smooth interior surface and an obround cross section, the obround cross section defined as having parallel opposing sides connected by two rounded opposing ends, where the parallel opposing sides are separated by a first distance, where vertices of the two rounded opposing ends are separated by a second distance, and where the second distance is greater than the first distance.

Abstract: A mechanical, M-to-N, reciprocating millimeter waveguide switch is provided, where M and N are integers. A mechanical, one-to-four, reciprocating millimeter waveguide switch is also provided, together with a method for switching millimeter waves from one input to one of four outputs is also provided.

Abstract: A blind mate waveguide flange includes a mating surface for interfacing with a waveguide probe interface. The mating surface includes a choke flange and a first opening to one end of a waveguide transition section. The choke flange includes a choke groove separating a peripheral region of the mating surface from an inner region of the mating surface. The inner region is recessed relative to the peripheral region to provide an air gap upon mating with another mating surface. The first opening has a first shape. The blind mate waveguide flange further includes a waveguide connection interface that includes a second opening at an opposite end of the waveguide transition section for interfacing with a waveguide. The second opening has a second shape such that the waveguide transition section provides a transition from the first shape to the second shape.

Abstract: Methods and systems for customized pet food are described. Generally, the systems and methods comprises obtaining a pet profile information from a user, which includes at least one of a species, an activity level, a medical history, a breed, a gender, a breeding status, a feeding method, an age, a spayed/neutered status, a snack schedule, a biological sample, a body condition, a dental health, a coat information, a digestive health information and a weight of the pet. The methods and systems may also comprise obtaining a second pet profile information from a user, related to a preference regarding an ingredient, a food form, a flavor, a protein source, a shape and a texture. The methods and systems also may include correlating the first pet profile information and second pet profile information to a stored nutritional information to determine a pre-made pet blend based.

Abstract: Methods and apparatus for magnetic resonance imaging (MRI) assisted cryosurgery. Optimal probe placements and cooling parameters are calculated prior to cryosurgery using MRI data. A MRI compatible cryoprobe and a stereotactic probe positioning device are provided. The resolution of MR images is enhanced by mounting a radio frequency MR coil on the intracorporeal end of a cryoprobe. During cryosurgery the temperature distribution in the frozen region is solved by determining the boundary of the frozen region and solving the heat equation for the known boundary conditions. During cryosurgery the temperature distribution in the unfrozen region is determined by T1 measurements. The process of freezing is controlled using information from the solution of the energy equation in the frozen region and temperature measurements in the unfrozen region. After cryosurgery the extent of the tissue damage may be ascertained using phosphorus-31 and/or sodium-23 spectroscopy with a special coil set on the cryosurgical probe.
