Indicator device
First Claim
1. An indicator device comprising:
- a removably mounted base member;
a first visual indicator and a second visual indicator;
a first indicator member mounted on the base member, and being displaceable manually and selectively between (1) a first position indicative of a first condition or state as determined by an observer and in which position the first visual indicator is revealed, and (2) a second position indicative of a second condition or state;
state as determined by the observer and in which the second visual indicator is revealed;
a first electronic tag and a second electronic tag, each of which is configured to-transmit readable information to an interrogation device; and
a shielding member that moves with the first indicator member and that prevents communication with the first electronic tag when the first indicator member is in its first position and that prevents communication with the second electronic tag when the first indicator member is in the second position.

Abstract
An indicator device comprises a first slide member (22) mounted on a planar base (1). The first slide member (22) is displaceable between a first position in which it reveals a first status indicating area (26) indicative of a first condition or state and a second position in which it reveals a second status indicating area (28) indicative of a second condition or state. A second slide member (30) is mounted on the base (10) and is displaceable into and across the path of the first indicator member (22) when the first indicator member is in the first position, to inhibit displacement of the first indicator member. The second indicator member (30) is displaceable between a first position in which it does not inhibit the displacement of the first indicator member (22) and a second position in which it inhibits the displacement of the first indicator member to its second position. The device may also be provided with one or more RFID tags (80, 82, 84) to permit remote monitoring of the status of the device. The device can be used, for example, in conjunction with a dispenser (60) to provide an indication of when stock needs to be reordered and whether reordering of the stock has taken place.

13. An indicator device comprising:
-
a first indicator member displaceable between a first position indicative of a first condition or state and a second position indicative of a second condition or state; and a second indicator member displaceable into a path of the first indicator member when the first indicator member is in the first position to inhibit displacement of the first indicator member to the second position, wherein the first and second indicator members are both displaceable in a straight line between their respective first and second positions and wherein the second indicator member is displaceable in a direction perpendicular to the direction of displacement of the first indicator member. - View Dependent Claims (14, 15)
