    Abstract: A chemical liquid injection system which a piston driving mechanism is driven only when a cylinder holding mechanism appropriately holds liquid syringes of various sizes through a cylinder adapter and such manner. When the liquid syringe 200S of a size other than the maximum size is appropriately held by the cylinder holding mechanism 120, RFID chip 230 is located on the side at the rear of metallic cylinder holding mechanism 120. A pair of resonance antennas are disposed on the left and right of the RFID chip, and an RFID reader 131 is disposed below the resonance antennas. When the liquid syringe 200S is appropriately held by the cylinder holding mechanism 120, RFID chip 230 wirelessly communicates with RFID reader 131 favorably, and the piston driving mechanism can be operated only in this state.

  • Patent number: 7247837
    Abstract: A soil moisture sensor uses a non-collimated light source and a photosensor, respectively, mounted at the foci of a transparent ellipsoidal plastic body. The dimensions of the body are such that emitted light rays are internally reflected toward the photosensor at the surface of the ellipsoid if the surface is dry, but refracted outwardly of the body when the surface is wet. The amount of light reflected onto the photosensor is thus a measure of the amount of moisture at the surface of the sensor. Direct illumination of the photosensor by the light source is prevented either by interposing opaque electronic components between them on a circuit board, or by taking advantage of light source characteristics to minimize the amount of transmitted light. If a circuit board is used, it is completely encapsulated against moisture penetration by fixing it in a carrier and molding the body around and onto the carrier to form a monolithic unit with the carrier and circuit board.

  • Patent number: 7015810
    Abstract: A control system (2) used for reaction equipment (20) and a monitoring device thereof are disclosed. The control system is connected to a computer (3) by signal, and includes the monitoring device and a portable alarm (24). The monitoring device includes a detector (21) for detecting the reaction action proceeded in the reaction equipment and outputting a detected value, an abnormal state assertor (22) in communication with the detector for giving an abnormal signal when the detected value is in the range of an abnormal state, and a wireless signal emitter (23) in communication with the abnormal state assertor for transmitting a wireless signal when receiving the abnormal signal. The wireless signal is received by the portable alarm and the portable alarm gives a warning signal to inform the user carrying with it.

  • Patent number: 6995676
    Abstract: A system is provided to monitor for moisture at separate locations interior to exterior structure cladding. The system includes a plurality of moisture sensors, at least one of which is disposed at each location to be monitored. Upon activation by the presence of moisture at its respective said location, the moisture sensor generates a signal. The system may also include a receiver in communication with the moisture sensors, to provide an identifier of the location of an activated moisture sensor. The moisture sensors and receiver may communicate via wiring, or wirelessly. The system so provided may be disposed within a single structure, or within a plurality of structures, with the receiver disposed within such a structure or remote to any such monitored structure.

  • Patent number: 6989755
    Abstract: A signal transmitting apparatus which makes exchanging information when pouring a liquid possible. A container body 201 of a transmitter side container 20 holds an electrically conductive liquid 402. A display 306 for confirming data reception is attached to a container body 211 of a receiver side container 21. The container body 201 and the container body 211 are electrically connected at a predetermined impedance by the liquid 402. Because digital data is modulated by a carrier of approximately 10 MHz, an electromagnetic field is generated. In particular, a return line 404 due to an electromagnetic near field is generated, and communications from the transmitter side container 20 to the receiver side container 21 becomes possible.

  • Patent number: 6975231
    Abstract: A method and apparatus that systematically prompts staff, patients and visitors at care facilities to perform handwashing at critical time periods, for example after touching a toilet flush handle or upon entering or leaving a patient's room. A plurality of detectors are used to sense whether a person has entered an area and to determine whether the person has cleansed their hands within a predetermined period of time before entering the area or leaving the area. If it is determined that the person has cleansed their hands within the predetermined period of time, no prompting message is generated. If it is determined that the person has not cleansed their hands within the predetermined period of time, an audio/visual warning message is generated.

  • Patent number: 6940409
    Abstract: A method and apparatus for monitoring fluid flow in a pipe or at an exit of the pipe and detecting a fault. The system includes an acoustic generator which is activated by the fluid flowing in the pipe or at the exit of the pipe. The acoustic generator sends an acoustic signal, which may have a distinctive signature, through the fluid flowing in the pipe. The acoustic signal is received by a remote upstream acoustic receiver and is translated into an electric signal supplied to a signal processor.

  • Patent number: 6930609
    Abstract: A device for transmitting data between a sensor, in particular a capacitive level sensor, and an analyser unit, whereby the sensor and the analyser unit are physically separate from each other and a method for operating said device. The device and method permit the testing and/or adjusting and/or operation of a sensor, which is active. A first processor unit is dedicated to the sensor and a second processor unit is dedicated to the evaluating unit. Connecting lines are provided, by means of which both processor units exchange bi-directional data.

  • Patent number: 6922144
    Abstract: A remote monitoring system for a mobile storage tank having a product container in which a remote telemetry unit gathers liquid level and head space pressure data and global position data. The remote telemetry unit effects a wireless transmission of a standard message structure containing the pressure and level data and the global position data. In addition, in case of a storage tank having a thermal shield fluid, pressure and level data for the shield fluid itself may also be in the standard data record as well as acceleration data from an accelerometer to indicate tank damage. If upset conditions of pressure and liquid level are reached in the thermal shield and/or product container, vapor may be vented in accordance with preset programming in order to attempt to reestablish liquid level and vapor pressure above set points.

  • Patent number: RE39871
    Abstract: A novel basic allergen/particulate data collection device and a novel multi-function personal air quality management device are disclosed. Both devices include sensor sub-assembly detecting and reporting on allergen/particulate data (preferably, for allergen/particulate with sizes smaller than 5 micron) for an indoor location (where the asthma patient is situated). Both devices are communication enabled to allow the allergen/particulate data to be provided to an air/asthma advice server, to generate air/asthma advice for an asthma patient, taking into consideration the allergen/particulate data as well as air quality data for a surrounding outdoor area of the indoor location. In one embodiment of the basic device, the communication interface is tailored for “harsh environment” local area networking.
