  • Patent number: 10186169
    Abstract: The present invention relates to systems and methods for assessing and improving an infant's oral feeding skills. The system comprises a “smart” baby feeding device comprising an instrumented baby bottle with a removable, battery-powered monitoring module wirelessly connected to a remote device (e.g., smart phone, tablet, laptop, PC). The purpose of the remote device is to monitor (in real time) and measure the frequency and quality of feedings of new-born babies to help optimize feeding development by providing real-time feeding performance information back to the caregiver. The information collected is of assistance in minimizing feeding difficulties and correcting feeding deficiencies.

  • Patent number: 10132096
    Abstract: The present invention relates to apparatuses for improving pool skimmers. In some embodiments, the apparatus is a pool skimmer basket system that includes a skimmer basket, a first tube that is attached to the skimmer basket, and a second tube that is adjacent to and rotatable relative to the first tube. The first tube includes a longitudinal slot that feeds water into the skimmer basket. Without being bound by any particular theory, it is believed that the slot increases the velocity of water flowing into the basket and that the system increases the debris-holding capacity and allows one to avoid having to reach through dirty water to remove the skimmer basket.

  • 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.

  • 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.

  • 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.

  • Patent number: 8834712
    Abstract: According to one embodiment, a seawater desalination system includes a membrane filtering pump, a first to third flowmeter, a filtering membrane, a high-pressure pump, a pressure gauge, a reverse osmosis membrane, a discharge valve and a control module. The membrane filtering pump outputs seawater according to a first control signal. The first flowmeter measures flow rate Q1. The high-pressure pump outputs filtered water from the filtering membrane according to a second control signal. The first pressure gauge measures pressure P1. The reverse osmosis membrane desalinates the filtered water into fresh water. The second flowmeter measures flow rate Q2. The third flowmeter measures flow rate Q3. The discharge valve discharges a high-concentration salt water according to a third control signal. The control module performs first, second, and third flow rate control with reference to the flow rate Q1, Q2 and Q3 and the pressure P1.
