6,385,505, issued on May 7, 2002 to Lipps, U.S. Pat. 9 illustrates a typical blister pack 901. Output 5902a is fed to a comparator 6001a, which compares the voltage of output 5902a with a first reference voltage 6002a. 20, 2012, U.S. Pat. While a rotation direction is shown for ease of explanation, the choice of rotation direction is arbitrary, and either direction may be used. 31. 12A and 12B, a light emitter and light receivers are positioned near the bottom of dispenser 1201, and operate similarly to light emitter 706 and receivers 707 described above with respect to dispensing mechanism 202. For example, an alternate cassette may have two vertical channels, and may be suitable for dispensing 5 ml vials having a diameter of about 25 mm. A General Surgery Patient Ward in a tertiary hospital with more than 1,300 beds … A cable (not visible) couples connector 4403 directly or indirectly with a circuit board 4503, to which a motor 4504 is connected. * Gutknecht M, Baehr M, Melzer S, Framke S. Poster anl. For example, uncoated tablets normally leave a layer of powder on any surface they touch, which can easily be transferred to other tablets or capsules counted on the same surface. When the slide is moved by the actuator, the slide translates against the action of the spring into a position in which the slot in the slide aligns with the opening in the tray, allowing a single item in the slot to fall through the opening to be dispensed. 18A and 18B, a button and light similar to button 601 and light 602 discussed above, for communication between a restocking technician or other user and computer 103 of cabinet 100. Other kinds of tamper-evident mechanisms may be used as well, instead of or in addition to ties 4201. 29, sprocket 2906 has a square cross section. 48 shows a cutaway oblique view of a portion of the cassette of FIG. 38 illustrates a lower oblique rear view of cassette 3602, showing a set of gears 3801, each of which is coupled to one of open-sided rotatable receivers 3704. The dispensing mechanism further comprises a moveable slide driven by the actuator, the moveable slide having a slot through the movable slide, into which slot items to be dispensed fall one at a time, and a spring that biases the slide into a default position in which the slot of the moveable slide is not aligned with the opening in the floor. 42 and 43 illustrate a number of ties installed in the openings shown in FIG. If different numbers of slotted gears are present, then a different angular separation of the gear positions may be used, but preferably slots 1704 reach the downward vertical orientation at evenly spaced angular intervals of the driving gear 1701. In this example, a blister pack 5701 interrupts the light emanating from emitter 5201 so that it does not reach receiver 5601. 29, in accordance with embodiments of the invention. FIGS. This wireless data exchange may use any suitable wireless protocol, for example Near Field Communications (NFC), radio frequency identification (RFID), or another wireless protocol. 8,073,563 to Vahlberg et al., issued on Dec. 6, 2011, U.S. Patent Application Publication No. Additional Dispensing Mechanism for Blister Packs and Other Small Items. FIG. 45 shows an oblique view of dispenser 4401 with some parts removed, revealing internal details of the operation of dispenser 4401. When an item is dispensed through opening 1206, it interrupts the light received by either or both light receivers, and dispenser 1201 can note that an item has in fact been dispensed. Dispenser 1801 defines an opening 1804 at the bottom of dispensing mechanism 203, through which items are dispensed. Dispensing mechanism 204 may be removably secured to one of rails 201 using a snap mechanism, one or more screws, or by another method. 26A and 26B illustrate a dispensing mechanism 2600 in accordance with other embodiments of the invention. While chamber 1005 is shown as being oriented vertically (being taller than it is wide), this is not a requirement. A microprocessor, microcontroller, or similar controlling circuitry may reside within dispenser 701, and may operate the various active components and sensors of dispenser 701 in response to high-level commands from a supervisory controller elsewhere within restock drawer 106, or from computer 103.
