Abstract: The present invention features the application of a simple, inductively-coupled measurement system into the cap of standard laboratory sample tubes, thus enabling continuous, wireless ionic sensing of a bevy of samples. The system may be powered by a compact Class E amplifier using inductive coupling via a designed resonance frequency of 1 MHz. Other frequencies can be used, such as the popular near-field communication (NFC) frequency of 13.66 MHz. Signals are transmitted back via load modulation at frequencies a fraction of the power carrier frequency, thus allowing for extraction of the signal frequency. Results clearly show that modulation frequency tracks closely with open circuit potential, and the system features good sensitivity and linearity. This system holds promise for a host of applications.

Abstract: A standpipe (15) for drawing water from a mains water supply. The standpipe includes an inlet 9 having a first coupling (7) configured to enable the standpipe to be connected to a hydrant outlet of the mains water supply and an outlet (5) having a second coupling (23) configured to enable a water delivery hose to be connected to the standpipe. A flow meter (3) measures a volume of water flowing from the inlet to the outlet and a data logger (19) is connected to the flow meter and records the volume of water measured. A global positioning system (GPS) module determines the location of the standpipe (15) when the flow meter 3 detects the water flow and a wireless communication module transmits the recorded volume of water and corresponding GPS location to a central monitoring facility (27).

Abstract: Apparatus for processing digital communications, comprising: input means arranged to receive input specifying an interrogation criterion; interrogation means arranged to interrogate a database of digital communications sent and/or received by a user, to produce a subset of digital communications in accordance with the interrogation criterion; and compilation means arranged to produce a compilation of the subset of digital communications, the compilation having the form of a human-readable document. Preferably the compilation has the visual appearance of a scrapbook. The digital communications may be inter alia e-mail messages, images and attachments; mobile text and picture messages; and instant messages.
