  • Patent number: 10969802
    Abstract: A solenoid operated unit (100) for detecting and removing an undesired fluid (6) from a desired fluid (5) with diagnostic metering, comprises a unified solenoid operated pump and valve unit (70), a drainage path (40), an electrical detection system (60), a mecha-electro-magnetic detection system (80) and a junction box (190) interacting with an electronic control unit (90) comprising a PWM generator. A plunger (50) moves from up to down, a sweeping volume (28) with a cycle of a PWM electricity wave, while moving down the plunger (50) creates a negative pressure in a sweeping volume (28) and while moving up a positive pressure gets created in the sweeping volume (28) and a negative pressure gets created at a rear end (30) of a unified chamber (26), an air reliever (180) is provided for breathing.

  • Patent number: 10711910
    Abstract: A solenoid valve (100) comprising a solenoid assembly (104) and a dual valve assembly (102) for fluid flow control and pressure relief. The dual valve assembly (102) comprising a valve body (300), upper stopper ring (113) and a lower stopper ring (307). A flow arrangement (200) comprising, a primary moving assembly (240) and a secondary moving assembly (213) is disposed inside the valve body (300). The primary moving assembly (240) having a primary mover (230) and an O-ring holder (208). The secondary moving assembly (213) comprising a sliding member (215), a supporting ring (214), a pressure-relief spring (211) and a pressure-adjusting mechanism (205). The flow arrangement (200) moves up when a solenoid coil (103) is energized resulting in normal fluid flow, the secondary moving assembly (213) moves down under excessive fluid pressure with the solenoid coil (103) de-energized. A reverse fluid flow is facilitated under excessive fluid pressure.

  • Patent number: 10053696
    Abstract: Breast cancer treatment methods and materials incorporating microRNA-489 are described. The methods and materials have been developed from identification of a double-negative feedback loop between miR-489 and the HER2-SHP2-MAPK signaling axis. The methods and materials may be particularly beneficial in treatment and diagnosis of HER2 positive breast cancers.

  • Patent number: 9951881
    Abstract: A solenoid operated unit for detecting and bleeding undesired liquid present in desired liquid of different resistivity and specific gravity, the two liquids being immiscible with each other; with an electrical arrangement having a pair of parallel sensor pins and a pair of serial sensor pins. A dual function diaphragm ensures suitability for use with contaminated fluids. A pressure equalization outlet ensures smooth and speedy bleeding of undesired liquid. A modular mechanical sensor, when provided, provides redundancy such that desired fluid is not drained in situations of any electro-mechanical failure.

  • Publication number: 20090256683
    Abstract: A system and method that facilitates the configuration and control of components of a radio frequency identification (RFID) system, taking into account how the RFID system components are associated with one or more physical locations within an environment in which the RFID system is deployed. The RFID system can be controlled by obtaining a representation of the physical space. Next, at least one region of interest is specified in the representation of the physical space. An interrogation zone is then specified in the representation of the physical space, in which the interrogation zone corresponds to the data reader. Next, at least one overlap region of the interrogation zone and the region of interest is specified. Information is then stored, including the representation, and the interest region, the interrogation zone, and/or the overlap region. Operation of the data reader is controlled as a function of the stored information.

  • Patent number: 7567179
    Abstract: A system and method that facilitates the configuration and control of components of an RFID system, taking into account how the RFID system components are associated with one or more physical locations within an environment in which the RFID system is deployed. A user provides information specifying associations between the system components and the physical locations within the environment to obtain visual representations of configuration data generated therefrom with reference to a facility view, an RF coverage view, and a location view of the data. The facility view serves as a reference plane for placement and orientation of antennas associated with RFID readers, location benchmark tags, and the physical locations of interest. After each antenna is placed and oriented on the facility view, an estimate of the size and shape of the RF interrogation zone of each antenna is computed, and representations of the RF interrogation zones are provided on the facility view to obtain the RF coverage view of the data.
