  • Publication number: 20240003584
    Abstract: A method is provided for controlling a heating, ventilation, and air conditioning (HVAC) system. The method includes measuring a temperature and controlling a compressor of the HVAC system. The temperature is measured by a temperature sensor located between a metering device of the HVAC system and an evaporator coil of the HVAC system. The temperature is representative of a refrigerant temperature. The refrigerant temperature is a temperature of a refrigerant fluid flowing from the metering device to the evaporator coil. The compressor is controlled by control circuitry that is configured to perform the controlling in a dehumidify mode based, at least in part, on a value of a humidity parameter of air of an airflow through an evaporator coil and a reheat coil, where the value is determined using the temperature.

  • Publication number: 20210369444
    Abstract: A system/method allowing hydrophilicity alteration of a polymeric material (PM) is disclosed. The PM hydrophilicity alteration changes the PM characteristics by decreasing the PM refractive index, increasing the PM electrical conductivity, and increasing the PM weight. The system/method incorporates a laser radiation source that generates tightly focused laser pulses within a three-dimensional portion of the PM to affect these changes in PM properties. The system/method may be applied to the formation of customized intraocular lenses comprising material (PLM) wherein the lens created using the system/method is surgically positioned within the eye of the patient. The implanted lens refractive index may then be optionally altered in situ with laser pulses to change the optical properties of the implanted lens and thus achieve optimal corrected patient vision. This system/method permits numerous in situ modifications of an implanted lens as the patient's vision changes with age.

  • Patent number: 9999499
    Abstract: A preloaded intraocular lens (IOL) system/method utilizing haptic compression is disclosed. The disclosed system/method utilizes an IOL packaged in a compressed state that is inserted into a patient using a cartridge and lumen through which the IOL is advanced. Within this context the haptics to the IOL are wrapped around the IOL in a coplanar fashion during the loading of the IOL to permit the IOL to be shipped and stored in a compressed state. This compressed state is achieve by wrapping the haptics of the IOL during the manufacturing process to ensure that the IOL is properly aligned and thus delivered in a predetermined orientation within the patient's eye. This compressed packaging of the IOL permits a more uniform and consistent placement of the IOL in the patient and eliminates the potential for physician error during the critical IOL placement procedure.

  • Publication number: 20150305933
    Abstract: A system is provided for noninvasive corneal refractive correction. The system includes an ortho-K lens specifically manufactured based on a topography of a cornea of a human eye for reshaping the cornea from a first configuration to a second configuration. The reshaping can be in situ or as a result of pre-laser treatment. The system also includes a laser device for initiating photochemical crosslinking within an internal layer of the cornea such that the crosslinked cornea remains substantially in the same shape as the second configuration without wearing the ortho-K lens. The laser device includes a laser source configured to produce output radiation in the form of light pulses, a scanner configured to distribute the light pulses in a predetermined pattern, and a light focusing objective configured to focus on an internal space of the cornea and deliver the light pulses into the internal space.
