Abstract: The electrode for recording a physiological electrical signal of a living being made from electrically conductive material and including a body having a front surface and a rear surface for electrical contact, the electrode further including a rigid mounting element attached to the body, at an edge of the rear electrical contact surface and designed so as to produce a removable mounting of the electrode on a recording sensor.

Abstract: A logging module for identifying a suspected tampering condition of an access-controlled container, the logging module comprising: data collection means configured to collect data from said access-controlled container; and communication means for communicatively connecting the logging module across a network to a database storing a use history associated with said access-controlled container; wherein the logging module is configured to compare the collected data to the corresponding use history associated with said access-controlled container stored in the database to identify a suspected tampering condition of said access-controlled container, wherein the use history comprises data associated with the weight and/or volume of content of the access-controlled container.

Abstract: A storage unit for storing a fluid, the storage unit comprising at least one wall defining a chamber and an opening. The storage unit comprises a storage unit valve arranged at the opening to selectively seal the chamber. The storage unit valve is able to be selectively opened and closed to allow fluid to flow through the storage unit valve. The storage unit comprises a storage unit keying mechanism configured to allow the storage unit to only connect to a complementary docking station keying mechanism disposed on a docking station for receiving the storage unit. The storage unit valve is configured to only be able to be selectively opened and closed when the storage unit keying mechanism is engaged with said complementary docking station keying mechanism.
