Abstract: Embodiments of a system and method for processing and recognizing non-contact types of human input to prevent contamination are generally described herein. In example embodiments, human input is captured, recognized, and used to provide active input for control or data entry into a user interface. The human input may be provided in variety of forms detectable by recognition techniques such as speech recognition, gesture recognition, identification recognition, and facial recognition. In one example, the human input recognition techniques are used in connection with a device cleaning workflow used to obtain data and human input during cleaning procedures while minimizing cross-contamination between the contaminated device or person and other objects or persons. In another example, the human input recognition techniques are used in connection with a device tracking workflow used to obtain data and human input while tracking interactions with and locations of the contaminated or uncontaminated device.

Abstract: Disclosed are cascaded refrigeration systems, comprising: a plurality of refrigeration units, each refrigeration unit containing a first refrigeration circuit, each first refrigeration circuit comprising an evaporator and a heat exchanger; and a second refrigeration circuit; wherein each first circuit heat exchanger is arranged to transfer heat energy between its respective first refrigeration circuit and the second refrigeration circuit.

Abstract: Disclosed are refrigerants, and heat transfer compositions, heat transfer systems and heat transfer methods containing such refrigerants, wherein the refrigerant comprises at least about 97% by weight of the following three components (a)-(c) and the following fourth component if present: (a) trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E)), (b) trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)), (c) trifluoroiodomethane (CF3I), and. (d) 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea).

Abstract: Disclosed are refrigeration systems having a heat source to be cooled and a heat sink and a capacity of from about 2 to about 30 tons and comprising: (a) a heat transfer composition comprising a refrigerant comprising at least about 80% by weight of trans1-chloro-3,3,3-trifluoropropene (HCFO-1233zd(E)) or at least about 80% by weight of trans1,3,3,3-tetrafluoropropene (HFO-1234ze(E)); (b) a centrifugal compressor having a discharge:suction pressure ratio at least about 2:1; (c) a condenser operating at temperature in the range of from about 10° C. to about 60° C.; (d) and expander for producing relatively cold low pressure refrigerant liquid; (e) a high efficiency evaporator; and (f) at least one heat exchanger fluidly connected between said evaporator and said refrigerant suction of said compressor.

Abstract: In certain embodiments a light therapy system (e.g., phototherapy device), such as for treatment of Alzheimer's disease, depression, dementia, short-term memory, or for improved learning, improved athletic performance or improved cognitive performance, is provided where the light system comprises a blue light source that operates at a frequency in the range from 20 to 50 Hz (preferably around 40 Hz), whereby the system enables retinal ganglion cells of a human to be exposed in order to stimulate brain waves (gamma oscillations in the human's brain).

Abstract: The present invention includes refrigerant composition, including trifluoroiodomethane (CF3I); 1,1,1,2-tetrafluoropropene (HFO-1234yf); difluoromethane (HFC-32); and pentafluoroethane (HFC-125), for use in a heat exchange system, including refrigeration applications and in particular aspects to the use of such compositions as a replacement of the refrigerant R-404A for heating and cooling applications and to retrofitting heat exchange systems, including systems designed for use with R-404A.
