  • Fixed network for an automatic utility meter reading system
    Patent number: 8896463
    Abstract: A fixed network for automatically reading a utility meter system has been developed. The network includes multiple meter interface units (MIUs) that each collect data from a designated utility meter. The collected data is transmitted to a primary data collector. The network includes multiple data collectors and each MIU identifies its own primary data collector based on signal quality between the collector and the MIU. The network includes a central host computer that is used to receive the collected data from the primary data collectors.

  • UTILITY DEVICE INTERFACE
    Publication number: 20140313050
    Abstract: A meter interface unit (MIU) is provided for a utility meter that uses RFID technology as both a source of backup power and as a means of transmitting utility usage data. Usage data is stored in non-volatile memory that will persist even if the main power source of the MIU is lost. Because an RFID generates electric current when it receives an electromagnetic signal from an interrogator, the RFID can provide power to the memory, read the usage data from the memory, and wirelessly transmit the usage data back to the interrogator without any other source of power. This can prevent data loss when the MIU runs out of power; for example, when its battery is expended. RFID technology can also provide many other benefits and uses when coupled with an MIU, in addition to serving as backup power and communication.

  • ADC TESTING
    Publication number: 20140203954
    Abstract: A histogram-based method for testing an electronic converter device, such as an analogue to digital converter, includes steps of defining at least one histogram hyperbin arranged to store hits for at least one subrange of output codes; applying an input test stimulus to an input of the device to test a subrange of output codes matched to the hyperbin; and accumulating the histogram. At least two hyperbins may be provided, each bin being arranged to store hits for at least one subrange of output codes, and the input test stimulus is applied to an input of the device to test a subrange of output codes matched to one of the hyperbins. Both hyperbins may be open while the histogram is being accumulated for any subrange of output codes. The method may further involve varying the input stimulus to test another subrange.

  • Determination and Display of LUN Encryption Paths
    Publication number: 20140164590
    Abstract: A management station which manages the encryption devices in a SAN to set up encrypted LUNs. In setting up the encryption, the source and target ports are identified, along with the target LUN. LUN serial numbers used to identify unique LUNs. As paths to a given LUN are defined, the management station compares the path to existing paths and provides an indication if there is a mismatch in the encryption policies or keys being applied to the LUN over the various paths. This allows the administrator to readily identify when there is a problem with the paths to an encrypted LUN and then take steps to cure the problem. By determining the paths and then comparing them, the management station greatly simplifies setting up multipath I/O to an encrypted LUN or access by multiple hosts to an encrypted LUN.

  • HVAC CONTROLLER WITH INTEGRATED METERING
    Publication number: 20140149270
    Abstract: A controller for a private unit in a multi-unit building is provided. The controller operates the private unit's HVAC equipment, and includes a processor, output display, memory, and a RF module for communication. The controller is operable to receive temperature or flow values of a fluid passing through the HVAC equipment. Using the received temperature values of the fluid passing through the HVAC equipment, the controller calculates a measured value of HVAC usage of the HVAC equipment. The measured value can be in units of energy or in dollars.

  • METHODS AND SYSTEMS FOR MONITORING THE SEVERITY OF INFECTION IN A GROUP OF INDIVIDUALS
    Publication number: 20140136556
    Abstract: A computer-implemented method of monitoring the severity of infection in a group of individuals. A set of data for each individual is obtained, the data comprising at least one piece of diagnostic test data indicating the level of a biomarker associated with the individual's response to infection. The data is then split into a plurality of segments, each segment comprising all data for each individual within a corresponding one of a plurality of time periods. For each segment, a level of the biomarker across the group of individuals during the time period is estimated. The level of the biomarker for each segment to is then determined provide an indication of the change in severity of infection in the group of individuals over time.

  • Fire Hose Testing Apparatus and Method
    Publication number: 20140039815
    Abstract: A method for testing a plurality of fire hoses having respective service test pressures and the test apparatus therefor wherein each hose is required to maintain a test pressure for a specified duration to pass the test. The test pressure is proportional to the service test pressure. Each hose is coupled to a respective hose fitting of a respective branch test conduit. Each branch test conduit includes an isolation valve, a pressure transducer, and a hose fitting downstream of the isolation valve. A variable frequency-variable speed controls a motor which drives a positive displacement water pump supplying water to and pressurizing a water header conduit and a plurality of branch test conduits interconnected therewith. An algorithm applied to the error signal for a respective hose line generates a pump speed command limited by the controller to regulate the rate of increase of pump output pressure.

  • Hot Water Heater Pre-Heating Apparatus
    Publication number: 20130186122
    Abstract: Disclosed is a hot water heater supplement and means of utilizing waste heat from a refrigeration cycle. The apparatus comprises a refrigerator having a compressible refrigerant, a compressor, a condenser, a refrigerant receiver tank, an expansion valve and an evaporator for changing the temperature, pressure and phase of the refrigerant in a standard refrigeration cycle. The condenser is a coaxial, water cooled heat exchanger that receives waste heat from the high temperature, condensing refrigerant. The heated water is pumped into a coaxial heat exchanger within a heat exchange tank, which heats a volume of water within the exchange tank that is then mixed with a hot water heater tank for use in a residence. Cold water is fed into the exchange tank and thus pre-heated before being moved to the hot water heater, which utilizes either a gas or resistance style heating means.
