By using more sophisticated monitoring strategies, accidental dispensing of multiple items may be detected. 6,011,999, issued on Jan. 4, 2000 to Holmes, U.S. Pat. Unit doses can come in blister packs. 49A and 49B show the locations of several openings in the cassette of FIG. For example, dispenser 1801 and cassette 1802 may snap together, may be separable with the removal of one or a small number of screws, or may be reasonably separable in some other way without damage to either dispenser 1801 or cassette 1802. FIGS. In addition, each dispensing unit can preferably also communicate to computer 103 the kind and quantity of items it contains and stands ready to dispense. ); ENTITY STATUS OF PATENT OWNER: LARGE ENTITY, ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNORS:WILSON, EDITH;MORENO, GERARDO;TREJO, GUILLERMO;AND OTHERS;SIGNING DATES FROM 20150711 TO 20150715;REEL/FRAME:047854/0596, ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNOR:FISHER, HERBERT LAWSON;REEL/FRAME:047854/0608, NOTICE OF ALLOWANCE MAILED -- APPLICATION RECEIVED IN OFFICE OF PUBLICATIONS, PUBLICATIONS -- ISSUE FEE PAYMENT VERIFIED, WELLS FARGO BANK, NATIONAL ASSOCIATION, AS ADMINIS, GRANT OF PATENT SECURITY INTEREST;ASSIGNOR:OMNICELL, INC.;REEL/FRAME:051048/0856, WELLS FARGO BANK, NATIONAL ASSOCIATION, AS ADMINISTRATIVE AGENT, NORTH CAROLINA, Bottled medicament automatic medicine-dispensing device, improved structure of medicine taking mechanism, Automatic dispensation device and medicine, Electronic dispenser for flexible rolled sheet material, Conveyor belt construction for vending machines, Dispensing devices with audible announcing means, Apparatus for feeding spinning or twisting machines, Pill counting apparatus having chute shifting on predetermined count, Rupturable blister pill package with safety backing, Automatic pill dispenser and method of administering medical pills, A dispenser for use with a drug dispensing apparatus, Interactive medication delivery system for individual pills and caplets, Medication transport and dispensing magazine, Methods and apparatus for dispensing items, Device and method for providing access to items to be dispensed, Methods and devices for dispensing pharmaceutical and medical supply items, Pharmaceutical dispensing device and methods, Method for controlling a drug dispensing system, Method for counting and dispensing tablets, capsules, and pills, Lighting system and methods for a dispensing device, Replacement liner and methods for a dispensing device, Interactive medication dispensing machine, Medication dispensing and monitoring system, Apparatus for controlled dispensing of pharmaceutical and medical supplies, Optical device for detecting a falling object, Apparatus for sensing a dropping tablet in medicine packing machine. 7A, a light emitter 706 and two light receivers 707 are positioned near the bottom of dispenser 701. 21A, cassette 1802 is empty, and in FIG. A drug dose is a specific amount or weight of medication. FIGS. 39A and 39B, a motor 3901 drives a belt 3902, which in turn drives gear 3903. 8 shows a partially cutaway oblique view of the dispensing mechanism of FIGS. FIG. While a rotation direction is shown for ease of explanation, the choice of rotation direction is arbitrary, and either direction may be used. 39B illustrates an oblique front view of the dispenser. Sensor electronics may sense the dispensing of syringe 2000a, or that slide 2204 is back to its nominal position, and may shut off motor 1904, stopping cam 1905. As shown in FIG. Dispenser 1201 can preferably automatically detect the installation and removal of cassette 1202. 27B) and returns to light receivers 2707, so long as it is not interrupted by an item being dispensed and falling through the “light curtain” formed across opening. Alternatively, motor 4504 may be a simple DC or AC motor, in which case dispensing may be accomplished by simply running motor 4504 until the dispensing of an item is detected, and then shutting off the motor. Similarly, comparator 6001c compares the voltage of output 5902c with a reference voltage 6002c, and produces output 6003c. 32 shows a rear oblique view of cassette 2702, and FIG. For example, dispenser 701 and cassette 702 may snap together, may be separable with the removal of one or a small number of screws, or may be reasonably separable in some other way without damage to either dispenser 701 or cassette 702. Dispensing Mechanism for Blister Packs and Other Small Items. This automatic detection may facilitate the inventory and tracking of items, and also can help prevent illicit diversion of items. In other embodiments, a dispensing mechanism in accordance with embodiments of the invention may not have the separable architecture of dispensing mechanism 2600, but may be a single unit including space for storing items to be dispense and including an actuator and other components for dispensing items. A reflective optical sensor may be provided within dispenser 701 that shines light (for example infrared light) onto the driving gear and can detect whether a return reflection is received. A microprocessor, microcontroller, or similar controlling circuitry may reside within dispenser 1801, and may operate the various active components and sensors of dispenser 1801 in response to high-level commands from a supervisory controller elsewhere within restock drawer 106, or from computer 103. 57 shows the light curtain of FIG. The dispensers may be placed in a dispensing unit that includes a lockable restock drawer and a dispense drawer into which items are dispensed by the dispensing mechanisms. What's a DOSIS? If no light interruption is detected despite a command to dispense an item, computer 103 may assume that a misfeed or other problem has occurred, or that cassette 2702 is empty. 47, in accordance with embodiments of the invention. The unit dose system may differ in form, depending on the specific needs of the organization. Slide 2204 is biased to the left by spring 2205, such that syringe 2000a remains suspended by ledge 2203. 54 shows a light curtain having a black surface 5401, with no item being dispensed. 4A. When one of the receivers reaches its upward vertical orientation and at least one vial is present in the corresponding vertical channel of cassette 3602 (not shown), the vial is free to drop into the respective receiver 3704. 36A and 36B, example dispensing mechanism includes a dispenser 3601 and a cassette 3602, which may be easily separable for restocking dispensing mechanism 3600. No. 5,805,456, issued on Sep. 8, 1998 to Higham et al, U.S. Pat. 48 shows a cutaway oblique view of a portion of cassette 4402, and illustrates the operation of a brake 4801. 37 and 38, gears 3801 rotate in synchronization. This may be helpful, for example, during shipment or transport of a full cassette, to prevent intentional or accidental removal of items from cassette 2702 by turning gear 2703. Unit extractor system of products for expending machines. 33 shows a magnified view of part of FIG. This wireless data exchange may use any suitable wireless protocol, for example Near Field Communications (NFC), radio frequency identification (RFID), or another wireless protocol. The dispensing mechanism also includes a housing defining opening at the bottom of the dispensing mechanism. 21, 2000 to Holmes, U.S. Pat. 7,348,884, issued on Mar. The detection may be accomplished in any suitable way, for example periodic polling using antenna 704, a contact sensor (not shown) that can detect the presence of cassette 702 electromechanically, or by another technique. Example dispensing devices are described in the following commonly owned U.S. Alternatively, motor 801 may be a simple DC or AC motor, in which case dispensing may be accomplished by simply running motor 801 until the dispensing of an item is detected, and then shutting off the motor so that motor 801 is advanced incrementally as far as is needed.
