A method carried out in a stock monitoring system, the stock monitoring system comprising: a housing, one or more doors disposed in or on the housing, a sensor for sensing the condition of the door(s) and providing a door closed signal indicative of the door(s) having been closed by a user; one or more containers for stock items, located within the housing, the or each container having associated therewith a weight sensor for providing a weight signal indicative of the current weight of the container, and control circuitry, coupled for communication with the weight sensor(s); wherein the method comprises (a) receiving a door closed signal; (b) receiving one or more weight signals; (c) determining, for the or each container, the number of stock items removed from the container(s) by the user, from the weight signal(s) occurring during a predetermined sensing period, the predetermined sensing period being dependent upon the door closed signal. A stock monitoring system is also disclosed. The stock monitoring system may further include a user ID sensor, adapted to be activated by a user, and/or one or more electrically controlled locks associated with the door(s), the lock(s) being electrically controllable such that the door(s) are in either a locked or releasable condition, the control circuitry being coupled for communication with the locks, and/or a display unit, the display unit including a indicator in a first colour, e.g. red, an indicator in a second colour, e.g. amber, and a main indicator, in a third colour, e.g. green. The doors may comprise exterior doors, or comprise lids of one or compartments within a drawer (in the latter case, the housing comprising one or more lockable drawers to which the user may gain access). |
