An embodiment provides a method for transferring information from at least one instrument to an application, including: establishing a central protocol structure, wherein the central protocol structure defines a format for information transmitted utilizing the central protocol structure; transmitting over a short-range wireless communication channel information from the at least one device to the application, wherein the information is formatted in a broadcast packet in view of the central protocol structure; receiving, at the application, information from the at least one device; and performing, within the application, an action with respect to the information within the application, wherein the performing comprises deciphering the information contained in view of the central protocol structure.

Dynamic wireless information transmission

One aspect provides a method including determining that an absolute pressure sensor is not submersed in a fluid; measuring an atmospheric pressure with the absolute pressure sensor to determine an offset pressure measurement; submersing the absolute pressure sensor in a fluid; and measuring pressure with the absolute pressure sensor; wherein a compensated pressure measurement of the fluid is determined. Other embodiments are disclosed.

Auto-zeroing absolute pressure sensor

Described is an apparatus and method employing one or more environmental instruments in communication with a communication server that monitors the operation of the environmental instruments based on a task schedule.

Server monitoring of flow and sampling apparatus and/or logger

Described is an apparatus and method for remotely controlling the call interval of an environmental instrument for a water quality monitoring apparatus based on environmental data obtained by one or more environmental instruments.

Blind logger dynamic caller

Described is a system for remotely monitoring water quality at one or more locations via a web-enabled application. Embodiments of the present invention provide remote water sampler control with integrated predictive sampling. In some embodiments, the present invention provides a web-hosted application that allows for remote user control of one or more water samplers in combination with predictive sampling.

Predictive and internet-based sampler control

A remote monitoring system is described which enables monitoring of flow meters or other scientific instruments from a remote location using the GSM cellular phone network. The system includes a wireless modem utilizing the GSM cellular phone network, a central processing unit, connection of a scientific instrument to the central processing unit, power supply (e.g. one or more batteries), and an enclosure for housing the components.
