  • Patent number: 12114947
    Abstract: A teleoperational system receives a movement command in response to movement of an input device, in response to determining an instrument is being controlled based on the movement of the input device, maps the movement command to a first movement of the instrument in an instrument frame using a first mapping, and in response to determining a tissue probe is being controlled based on the movement of the input device, maps the movement command to a second movement of the tissue probe in a tissue probe frame using a second mapping. The first mapping maps motion in an input direction in the input frame to an instrument direction in the instrument frame. The second mapping maps motion in the input direction to a tissue probe direction in the tissue probe frame. The instrument direction corresponding with the input direction. The tissue probe direction not corresponding with the input direction.

  • Patent number: 5265437
    Abstract: The potential for leakage of CFCs, HCFCs, HFCs and HCs to the atmosphere as a result of leakage in vehicular refrigeration systems is reduced by employing conduits (42, 58 and 63) of relatively short length to interconnect closely grouped system components including a compressor (38), a condenser (44) and an evaporator (62). The condenser (44) includes a liquid flow path (46) in heat exchange relation with a refrigerant flow path (48) and the same is connected by conduit (52) to heat exchanger (36). The evaporator (62) also includes a liquid flow path (65) in heat exchange relation with a refrigerant flow path (60) and the same is connected by conduits (66, 67) to at least one heat exchanger (68, 69) remote from an engine compartment (22) in which the compressor (38), condenser (44) and evaporator (62) are housed. The close proximity of the components minimizes the charge of refrigerant required and thus reduces the amount of refrigerant that may potentially leak from the system.

  • Patent number: 5064526
    Abstract: A method for the decomposition of halogenated and non-halogenated organic contaminant compounds contained in a contaminated medium comprises adding an alkali or alkaline earth metal carbonate, bicarbonate or hydroxide to the contaminated medium in an aqueous solution or in a solvent having a boiling point of at least 200.degree. C., or in the form of a solid dispersion or suspension. The medium includes a hydrogen donor compound. The hydrogen donor compound may be originally contained in the medium or may be added to the medium. The medium further includes a catalytic source of carbon, for example, a carabohydrate, which will cause formation of a free radical hydrogen ion from the hydrogen donor compound. The medium is heated to dehydrate the medium and then is further heated at a temperature between about 200.degree. and 400.degree. C. to cause formation of the free radical hydrogen ion and effect reductive decomposition of the halogenated and non-halogenated organic contaminant compounds.
