  • Patent number: 9345827
    Abstract: Prior to each treatment session for an individual patient, a machine controller in a dialysis machine obtains from a logic device a set of current control settings of the machine-related parameters to be applied in the treatment session. In generating the control settings, the logic device obtains a set of therapeutic targets comprising a target value that represents part of a desired status of the patient after the treatment session, in terms of one or more physiological parameters for the patient. The logic device also obtains status data that represents the current status of the patient prior to the treatment session, and computes the set of current control settings of the machine-related parameters, as a function of the set of therapeutic targets and the status data and at least partly based on a predictive model, which estimates the physiological response of the patient to the machine-related parameters during the treatment session.

  • Patent number: 9074355
    Abstract: A domestic water recycling system using a combination of an optical detector to detect certain smaller sized (non-filtered) contaminants and a filter to remove larger sized (filtered) contaminants provides an efficient wastewater recycling system. Optical detection of contaminants determines whether water is discharged or filtered and recycled. The optical detection system can use several discrete optical wavelengths that are passed through the fluid, and can determine a relative presence of the contaminants based on the resulting wavelength response. A recycling shower using optical detection, an electronically actuated directional device and pump and a controller allows for automatic recycling or discharging of water without requiring user input. The system may include a turbulence reduction baffle in a collection chamber, and a disinfection unit for the recycled water.

When the valve member is in the first position, incoming water is directed to the filter element to remove sediment and impurities from the water. When the valve member is in the second position, the incoming water is blocked from passing through the filter element and the valve member. Lastly, when the valve member is in the third position, the incoming water passes through the valve member and not the filter element so that the filter element can be removed and replaced without interrupting the incoming water flow.

  • Patent number: 8882998
    Abstract: The present invention relates to the field of perfumery and more precisely it concerns a device, and the consumer articles associated therewith, for dispensing an active composition into the surrounding space. The device includes an assembly containing a reservoir holding the active liquid to be diffused into the surroundings and a wick-/emitting member structure composed of a wick member and an emitting/diffusion member, the latter having an evaporative surface to be directly exposed to the surrounding space when the device is activated, the assembly being housed in a casing or carried by a supporting frame, the device further including a pivoting member fixed on the casing or on the supporting frame to allow a swinging motion of the assembly and thus forced evaporation of the active volatile whenever desired.

  • Patent number: 8871062
    Abstract: An apparatus and method are disclosed for controlling the thickness of a flowing, laminar fluid film. The film flow may be gravity-induced or the result of an alternative force. The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. For example, in some applications, it may be desirable to maintain an approximately constant film thickness as the fluid flows over the active region of the surface. The geometry of the flow surface is used to obtain the desired control over the fluid film thickness. The flow surface is the outer surface of a solid with a closed upper end and a lower end that may be open or closed.

  • Patent number: 8864985
    Abstract: A method and apparatus for operating on skimmed oil/water picked up from a body of water to separate the oil from the water and discharge the oil-free water back into the body of water, first feeds the skimmed oil/water into a gravity settling tank wherein the oil tends to settle above the water, removing relatively oil-free water from the bottom of the tank and measuring its oil content with an oil concentration sensor, and either returning the oil/water flow to the settling tank for further processing if the measured concentration of oil exceeds predetermined limits or discharging the water back into the body of water if the oil concentration is measured to be less than the predetermined value.

  • Publication number: 20140299550
    Abstract: A method and apparatus for treating water including a tank having an inlet and outlet and a water treatment material or resin within the tank. A control valve assembly having multiple, separable levels houses a water usage metering mechanism and a regeneration control mechanism, each having associated turbines. An inlet/bypass valve communicates source water with the tank inlet or directly to a system outlet. When the treatment material is exhausted, it is regenerated by actuating the bypass valve to communicate the source water with the system outlet. The turbine driven regeneration control then sequences the steps of regeneration, including opening a control valve to communicate inlet water to a venturi in order to aspirate brine solution and deliver to the tank outlet. The brine solution passes through the treatment material and is discharged through the tank inlet which is communicated to a system drain.

  • Patent number: 8845887
    Abstract: A water purifier determining an appropriate discarded water quantity includes: a purified water supply; an integrated flow quantity measuring part; and a control and calculation part. The control and calculation part is configured to determine whether purified water is unsuitable for use based upon the integrated flow quantity measured for a period of time from when the supply is started. A value of water quantity Qti at the Nth time is determined based on a length of time from when the purified water supply stops the supply at the (N?1)th time up to when the purified water supply starts the supply at the the Nth time; and a difference between a quantity of water measured for a period of time from when the supply at the (N?1)th time is started to when the supply at the (N?1)th time is stopped and a value of Qti at the (N?1)th time.
