Methods, devices, and systems have been developed in various fields of technology for electronic communication. For example, circuit boards have been used in various methods of electronic communication to provide physical support for various electrical components and to electrically couple various electrical components together.
A circuit board can, for instance, be used to mechanically support and electrically connect electronic components using conductive pathways and/or traces, etched from copper sheets laminated onto a non-conductive substrate. A common type of circuit board is a printed circuit board (PCB).
Printed circuit boards can be made by bonding a layer of copper over the entire substrate and removing unwanted copper after applying a temporary mask (e.g. by etching), leaving only the desired copper traces. Some printed circuit boards can be made by adding traces to the substrate by a complex process of multiple electroplating steps.
Some approaches for printing a circuit board using subtractive method include silk screen printing, photoengraving, and PCB milling, among others. Silk screen printing, for example, can use etch-resistant inks to protect the copper foil and subsequent etching removes the unwanted copper.
Photoengraving can use a photomask and chemical etching to remove the copper foil from the substrate. PCB milling can use a two or three-axis mechanical milling system to mill away the copper foil from the substrate.
Electronic components can be attached to a printed circuit board to form a functional printed circuit assembly (PCA). In through-hole construction, component leads can be inserted in holes. In surface-mount construction, the components can be placed on pads and/or lands on the outer surfaces of the printed circuit board. In both kinds of construction, component leads can be electrically and mechanically fixed to the board with molten metal solder. The electrical components can be electrically coupled together to form an electrical, device that can be part of a communications system.
A number of electrical components can be physically and electrically coupled to the circuit board. Such circuit boards can, for example, include communications modules that can be used in a system for electrical communication, including wireless communication.
A component's placement on the circuit board is dependent on the contact pattern that is created by the contacts on the circuit board. Circuit boards can be mass produced at a reduced cost, but are limited in their functionality as they are designed to be used in one configuration with one set of components. Accordingly, when a new configuration is to be used, a circuit designer has to create a new design, verify that the design will work, and in some instances, get the design approved for use.
Circuit boards can also be custom fabricated to create any desired contact pattern that can accommodate a given electrical component. Circuit boards with a custom contact pattern are flexible with regard to their electrical component compatibility, but can be more costly and/or time consuming to fabricate.
In the field of wireless sensing circuits for monitoring the activities of an individual, a circuit board assembly for a sensor has at least one sensing component, a power supply, and a communications component, however, the types of components used may differ by application. As discussed above, each time a different component is to be implemented, the circuit designer has to design, assemble, verify it will work for the application based upon the characteristics of the circuit and have the circuit approved for use, if necessary. This can be a time consuming and/or expensive process in some instances.
Embodiments of the present disclosure include systems, methods, and devices for electronic wireless communication in circuits for monitoring one or more activities of an individual. Some embodiments, for example, include a carrier board portion. The carrier board portion can have a module contact pattern to electrically connect a module, selected from a plurality of different module types that each have a contact pattern that corresponds to the module contact pattern of the carrier board portion, to a number of electrical components attached to the carrier board portion.
In various embodiments, wireless communication can occur through the use of communications modules on the circuit board. As stated above, electrical components, such as a communications module, can be coupled to the carrier. This can be accomplished, for example, by utilizing a circuit board that has a number of contacts where electrical components can be coupled. Such circuit boards can couple various electrical components together via the contacts and electrical conductive paths designed and arranged on the carrier.
Accordingly in some embodiments, a carrier of a circuit board can be designed to include various contact patterns arranged on the carrier to accommodate the coupling of various electrical components. The arrangement of the various contact patterns on the circuit board can be a factor in determining what electrical components can be coupled to the carrier.
However, in circuit board manufacture, the amount of space a board takes up and/or the functionalities to be placed on the board can determine the design of the components on the board and/or the arrangement of such components, in some instances. This can also be the case with arrangement of components, such as a communications module, on a board (i.e., daughter board) to be attached to a carrier. Accordingly, when different components are positioned on a daughter board, this arrangement regarding the size and/or shape of the daughter board and arrangement of components thereon may impact the design of the carrier, in some instances.
Embodiments of the present disclosure standardize the shape of the daughter boards that can be used with the carrier and/or standardize the contact pattern used to connect the daughter board to the carrier. Such embodiments allow use of a universal carrier design and/or universal daughter board design that can be implemented such that any of a plurality of daughter boards can be utilized with a carrier.
By making the contact pattern uniform, each of the carrier component configurations and/or the daughter board component configurations can receive Federal Communications Commission (FCC) and/or Underwriters Laboratory (UL) approval independently, in some applications. This can allow for the use of a number communications module types to be added to the carrier without having to be FCC and/or UL approved as a whole unit or can reduce the time line for such approvals and/or qualifications.
For example, in various embodiments, the circuit board can be utilized with a number of different communications modules that have a contact pattern to accommodate placement on the carrier (e.g., a carrier circuit board). The number of different communication modules can, for example, be WiFi, Bluetooth, Dust, and/or Zigbee 802.11/802.15.4 communications modules, among other types.
Each communications module and/or daughter board component configuration, which can include a communications module, can receive separate FCC and/or UL approval among other certifications, qualifications, and approvals. Again, these FCC and/or UL approvals allow for a number communications module types to be added to the carrier without having to be FCC and/or UL approved as a whole unit or can reduce the time line for such approvals and/or qualifications of the whole unit.
In various embodiments, the circuit board can include a number of contacts on the carrier. The contacts on the carrier can, for example, be power, ground, digital communication, digital input/output (I/O), and/or analog I/O contacts, among other contact types. In some embodiments, the contacts on the carrier can be leadless castellations.
The carrier can include the power supply to the electrical components on the carrier. Also, the carrier can include the interface connections between the modules on the carrier, light emitting diode (LED) status indicators for the electrical components on the carrier, reset buttons for the electrical components on the carrier, and various sensors, such as magnetic reed switches and/or temperature sensors.
The circuit board can be designed to accommodate a daughter board on the carrier. The daughter board can, for example, have inputs and/or outputs for digital sensors, analog sensors, and/or discrete sensors, among other components.
The daughter board can be used to implement the sensor functionality by coupling the sensors to electrical components on the daughter board, the carrier board, and/or other components in a communication system. The daughter board can include a communications module. Communications modules can provide for the connectivity between various electrical components of a communication system.
In various embodiments, the electronic communication can be part of a wireless communication system including a circuit board with a carrier. In such embodiments, the carrier can, for example, have a contact pattern and a communications module. In some embodiments, the carrier can have a contact pattern to accommodate a contact pattern for the communications module of a wireless communications device.

In some embodiments, the sensors can be activity sensors that can wirelessly communicate data for monitoring an individual's daily living activities.

In various embodiments, a system for wireless communication can include a number of sensors each having a wireless communications component. In such embodiments the wireless communications component can, for example, include a carrier board portion.
In some embodiments, the wireless communications component can also include a communications module portion. The module portion can, for example, have a contact pattern to accommodate a contact pattern for the module contact pattern. The module portion can also include a computing device that can receive information transmitted from at least one of the number of sensors via the wireless communications component.
In some embodiments, the information can be sensor data from one or more of the number of sensors and can be data about an activity of daily living based upon one or more activations of a sensor. In some embodiments, the information can, for example, be sensor performance data (e.g., sensor activation thresholds, power output) and/or sensor status data (e.g., battery power, signal strength, software or firmware update information).
In various embodiments, a kit for assembling a circuit board can include a carrier
board portion. In some embodiments, the kit for assembling a circuit board can include a plurality of communications module portions. The module portions can, for example, each have a contact pattern to accommodate a contact pattern for the module contact pattern.
