Patent Application
20230000724
The present invention relates in general to the field of medical devices, and particularly to devices, systems and methods for dispensing one or more regimens of pills to a user.
No matter how old you are, it can be easy to lose track of the last time you took your medication. One way to stay on track with any medications you need is to use a pill dispenser. These days, there are many options alongside the typical pillbox divided for days of the week. Some pill dispensers merely organize pills in clearly labeled boxes while others have special alarms to indicate that it's time to take medication or even notify you when it's time to renew your prescription.
The MedaCube Dispenser and the Hero Automatic Medication Dispenser are examples of existing technology. None of these are modular, stackable or scalable.

The embodiments are used to dispense a variety of pill based medications in a varying number of regimens to a user. A single dosage of a mediation is inserted into each compartment by the user, for example, using a pill loading accessory. Each tray may contain a single type of medication. Individual trays are configured to dispense a medication on a set regimen. When the base unit detects that it is time for a medication of a particular regimen to be dispensed, it will activate any tray that is configured for that regimen to dispense a single dosage of that medication. When activated, a tray will advance the compartments forward by one position, causing a single dosage of medication to fall through an opening in the bottom of the tray. The opening will allow the medication to fall through the device and into a receptacle. Once all medications for a particular regimen have been dispensed, a notification may be triggered informing the user that it is time to take their medication.

Various computer hardware, software and firmware may be included within each component as would be appreciated by those skilled in the art. An example of the computer or processor logic will be described below.
The controller 202 and sensor board 319 may contain circuitry (e.g. on a printed circuit board) including a computer chip, or logic, that utilizes a microcontroller, memories, and a radio or wireless transceiver to operate. The logic circuitry may be referred to as an integrated circuit chip or processor which may be implemented in hardware, firmware, or a combination of hardware and software. Such a processor may include a processor (e.g., a central processing unit (CPU), a graphics processing unit (GPU), an accelerated processing unit (APU), etc.), a microprocessor, and/or any processing component (e.g., a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), etc.) that interprets and/or executes instructions. In some implementations, the processor may include one or more processors capable of being programmed to perform a function. An associated memory may include a random access memory (RAM), a read only memory (ROM), and/or another type of dynamic or static storage device (e.g., a flash memory, a magnetic memory, an optical memory, etc.) that stores information and/or instructions for use by the processor.
A communication interface (e.g. associated with controller 202) may include a transceiver-like component (e.g., a transceiver, a separate receiver and transmitter, etc.) that enables the controller 202 to communicate with other devices, such as via a wired connection, a wireless connection, or a combination of wired and wireless connections. Communication interface may permit devices to receive information from another device and/or provide information to another device. For example, communication interface may include an Ethernet interface, an optical interface, a coaxial interface, an infrared interface, a radio frequency (RF) interface, a universal serial bus (USB) interface, a Wi-Fi interface, a cellular network interface, or the like.
The components may perform one or more processes described herein, for example, in response to controller 202 executing software instructions stored by a non-transitory computer-readable medium. A computer-readable medium is defined herein as a non-transitory memory device. A memory includes memory space within a single physical storage device or memory space spread across multiple physical storage devices.
Software instructions may be read into a memory from another computer-readable medium or from another device via communication interface. When executed, software instructions may cause controller 202 or processor to perform one or more processes described herein. Additionally, or alternatively, hardwired circuitry may be used in place of or in combination with software instructions to perform one or more processes described herein. Thus, implementations described herein are not limited to any specific combination of hardware circuitry and software.
The number and arrangement of components shown in
In the controller 202 the logic circuitry may drive a display screen, manage battery life, and manage the wired/wireless communication. The logic circuitry may drive a navigational menu that may be displayed on the display of the user interface. This menu, and associated control buttons or touch screen, may control all operational and transmission functions of the device.
It will be apparent that systems and/or methods, described herein, may be implemented in different forms of hardware, firmware, or a combination of hardware and software. The actual specialized control hardware or software code used to implement these systems and/or methods is not limiting of the implementations.

Further note that if the processing module, module, processing circuit, and/or processing unit implements one or more of its functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the memory and/or memory element storing the corresponding operational instructions may be embedded within, or external to, the circuitry comprising the state machine, analog circuitry, digital circuitry, and/or logic circuitry. Still further note that, the memory element may store, and the processing module, module, processing circuit, and/or processing unit executes, hard coded and/or operational instructions corresponding to at least some of the steps and/or functions illustrated in one or more of the Figures. Such a memory device or memory element can be included in an article of manufacture.
The present invention has been described above with the aid of method steps illustrating the performance of specified functions and relationships thereof. The boundaries and sequence of these functional building blocks and method steps have been arbitrarily defined herein for convenience of description. Alternate boundaries and sequences can be defined so long as the specified functions and relationships are appropriately performed. Any such alternate boundaries or sequences are thus within the scope and spirit of the claimed invention. Further, the boundaries of these functional building blocks have been arbitrarily defined for convenience of description. Alternate boundaries could be defined as long as the certain significant functions are appropriately performed. Similarly, flow diagram blocks may also have been arbitrarily defined herein to illustrate certain significant functionality. To the extent used, the flow diagram block boundaries and sequence could have been defined otherwise and still perform the certain significant functionality. Such alternate definitions of both functional building blocks and flow diagram blocks and sequences are thus within the scope and spirit of the claimed invention. One of average skill in the art will also recognize that the functional building blocks, and other illustrative blocks, modules and components herein, can be implemented as illustrated or by discrete components, application specific integrated circuits, processors executing appropriate software and the like or any combination thereof.
The present invention may have also been described, at least in part, in terms of one or more embodiments. An embodiment of the present invention is used herein to illustrate the present invention, an aspect thereof, a feature thereof, a concept thereof, and/or an example thereof. A physical embodiment of an apparatus, an article of manufacture, a machine, and/or of a process that embodies the present invention may include one or more of the aspects, features, concepts, examples, etc. described with reference to one or more of the embodiments discussed herein. Further, from figure to figure, the embodiments may incorporate the same or similarly named functions, steps, modules, etc. that may use the same or different reference numbers and, as such, the functions, steps, modules, etc. may be the same or similar functions, steps, modules, etc. or different ones.
The above description provides specific details, such as material types and processing conditions to provide a thorough description of example embodiments. However, a person of ordinary skill in the art would understand that the embodiments may be practiced without using these specific details.
Some of the illustrative aspects of the present invention may be advantageous in solving the problems herein described and other problems not discussed which are discoverable by a skilled artisan. While the above description contains much specificity, these should not be construed as limitations on the scope of any embodiment, but as exemplifications of the presented embodiments thereof. Many other ramifications and variations are possible within the teachings of the various embodiments. While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best or only mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims. Also, in the drawings and the description, there have been disclosed exemplary embodiments of the invention and, although specific terms may have been employed, they are unless otherwise stated used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention therefore not being so limited. Moreover, the use of the terms first, second, etc. do not denote any order or importance, but rather the terms first, second, etc. are used to distinguish one element from another. Furthermore, the use of the terms a, an, etc. do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item.
