Abstract

A wireless instrument and methods for the remote monitoring of a plurality of biological parameters is described. The instrument includes a means of receiving data from a plurality of sensors, a means for converting the sensor data to a digital format, a means for collating the digitised sensor data into a single digital data stream, a transmitter for modulating a carrier signal with the digital data stream to create a modulated signal suitable for wireless transmission, an antenna for generating a radiating electromagnetic field to be received by a remote receiver, and an electrical power source. In a further embodiment, an additional means is provided for including an identification code in the transmitted digital data stream. In a further embodiment, an additional means is provided for monitoring operational parameters of the instrument and the inclusion of the monitored operational parameters in the transmitted digital data stream. In a further embodiment, an additional means is provided that allows for receiving signals from a remote transmitter for the remote manipulation of the instrument. In a further embodiment, the electrical power source is rechargeable and a recharging means is provided. A method is described for encapsulating the instrument in a one-piece housing that may include additional materials for increasing the mass of the instrument.
