Abstract: Heat pumps for climates where demand for cooling and heating are unequal and methods of adapting and distributing heat pumps for such climates. Heat pumps include a compressor, compressor motor, variable speed drive, and controller. In a number of embodiments, non-volatile memory stores sets of constant speeds for cooling and heating, and a person can select, via an input device, different sets of speeds for cooling and heating to provide the different cooling and heating capacities. The controller then operates the unit at the selected speeds, selecting from within the set based on demand for cooling or heating. In some embodiments, different sets of speeds may have the same minimum speed but different maximum speeds. Identical heat pumps can be configured to have different capacity ratings and different advertised efficiencies for different climates.

Abstract: A system and method for controlling noise produced by an air handling system is provided. The system includes a source microphone to collect sound measurements from the air handling system and a processor to define a cancellation signal that at least partially cancels out the sound measurements. The system also includes a speaker to generate the cancellation signal. The sound measurements are at least partially canceled out within a region of cancellation. Accordingly, the system further includes a response microphone to collect response sound measurements at the region of cancellation. The processor tunes the cancellation signal based on the response sound measurements.

Abstract: A system for determining the directional properties of surface waves or internal waves of a fluid medium includes a sonar system having a plurality of transducers for generating respective, separate acoustic beams and receiving echoes from one or more range cells located substantially within the beams; and a computer program for determining the directional properties associated with the surface waves or internal waves from the received echoes, wherein the computer program determines along-beam velocities along the separate acoustic beams and combines the along-beam velocities to form an equivalent orbital velocity vector. The system is mounted on or in a sub surface buoy that can move or rotate during measurement and includes a motion sensor measuring six degrees of freedom to account for horizontal velocity and vertical displacement in the subsurface buoy mounted sonar system.

Abstract: A label applicator for dispensing and applying labels to articles includes a label leading edge indicating sensor and an adjustable peel bar held at a pickup position. A label support may be used with larger labels that have been partially peeled from a backing strip and remain at the pickup position. Printed labels to be applied to an article have a portion of the surface area of an adhesive side removed from the backing strip before the label is taken by a label pick-up-and-applicating device. A print head may be included in the label applicator between the indicating sensor and the adjustable peel bar. A number of labels may be picked-up simultaneously from the backing strip by a number of pick-up heads to be applied to a number of separate articles.

Abstract: A method and apparatus for determining the surface level of a given body using acoustic ranging that incorporates processes natural to human beings to improve identification of the echo from the water surface when spurious echoes might otherwise overshadow it. An acoustic beam is transmitted toward the surface where it is reflected. The beam also reflects off various interferences creating spurious reflections or echoes. The echoes from the surface as well as the spurious echoes are then received. Each echo is then evaluated according to several criteria, in order to determine which echo is associated with the surface.
