In the UK electricity system, a data collector (DC) is responsible for determining the amount of electricity supplied so that the customer can be correctly billed.

Wetness monitoring system

The present invention relates to a wetness monitoring system that includes a data collection device that sends wetness measurement data to a central computer that detects changes in wetness measurement data caused by the presence of urine or other dielectric fluids. The data collection device includes a semi-reusable sensor and reusable data collector that are worn on a garment of the person. The data collector includes an internal power source so that the person can live a normal ambulatory life. The data collector has an electrical circuit that uses the changing resistance characteristics in the sensor to gather wetness measurement data. The data collector periodically generates and transmits a signal containing the actual wetness measurement data. The signals are coded to identify the particular data collector or person sending the signal. The data collector is programmed to conserve power by sending signals less frequently during periods when the sensor is clearly dry. Signals are sent more frequently when the sensor is damp or a wetness event may have occurred. The central computer receives the signals containing the wetness measurement data and compares the measurement data to an adjustable wetness sensitivity level to determine if a wetness event has occurred. When the central computer determines that a wetness event has occurred, the computer displays the name of the particular person wearing the data collector and the approximate time that the wetness event occurred. The system then pages an appropriate healthcare worker to inform them that the particular individual needs attention and tracks the approximate response times to ensure that the patient is continuously receiving prompt care.

Method and apparatus for customizably calculating and displaying health of a computer network

Apparatus and methods facilitate customizable and extensible performance monitoring of a computer network. One method accepts a composite score definition in terms of N system variables, wherein N≧2; determines N raw data values, each raw data value corresponding to one of the N system variables; computes the composite score in accordance with the definition using the N raw data values as inputs; and outputs the composite score. The composite score definition is preferably in the form of a markup language, such as XML. The composite score definition preferably comprises, for each of the N system variables, a mapping and a weight. Preferably the composite score is displayed in at least one graphic form, such as a dial gauge, a bar indicator or a number, on a hypertext page. The hypertext page preferably contains one or more links to hypertext pages containing information regarding the scores and / or raw data values from which the composite score is derived. Another method accepts a mapping by which a raw data value associated with a corresponding system variable is mapped to a score, determines a raw data value corresponding to the system variable, converts the raw data value to a score in accordance with the mapping; and produces an output based on the score. One apparatus comprises a composite score definition, a data collector, a calculation logic and an output. The data collector collects a raw data value corresponding to one of the N system variables. The calculation logic is connected to the data collector and calculates the composite score in accordance with the definition using the N raw data values as inputs. The composite score is conveyed by way of the output. Preferably, the data collector comprises a database in which at least some of the raw data values are stored and a communication module by which at least some of the raw data values are transported, preferably according to the SNMP and / or the ICMP protocols. Another apparatus comprises a mapping, a data collector, a converter and an output. A raw data value associated with a corresponding system variable is mapped to a score, according to the mapping.
