DESCRIPTION OF WIRELESS CONTROL OF LINEAR ELECTROMAGNETIC ACTUATOR
Child Proof System
[0022] The instant invention is a system for remotely locking and unlocking multiple storage units (e.g. drawers, cabinets) simultaneously or selectively. The storage units can include, for example, cabinet doors and drawers in the kitchen, living room, bathrooms, and so on.
[0023] The system comprises a controller, described infra and supra.
[0024] The system works via a plurality of electromagnetic locking devices (herein linear electromagnetic actuators) coupled to the controller. The system further comprises a remote control unit that is [preferred embodiment] wirelessly coupled to the controller.
[0025] The remote control unit allows the user to send instructions to the controller to either simultaneously lock or unlock all the electromagnetic locking devices associated with the controller or facilitate the locking and unlocking of any particular electromagnetic device associated with the controller.
[0026] As an alternative to the remote control unit, the controller can also be coupled to a smart device (smartphone, tablet, laptop, and the like) via a mobile App or a tablet/laptop/desktop program. The connection between the smart device and the controller can be then facilitated either by WiFi, Bluetooth, infrared, and other such communication means.
Two Primary Embodiments
[0027] The System is primarily Embodied as a Wired or a Wireless System:
A. Wired System Embodiment:
[0028] In the wired system, the controller is connected to all of the electromagnetic locking devices via wires. Both the controller and the electromagnetic locking devices can have special connectors for facilitating the connections (e.g., snap fit connectors (quick connect/disconnect), using screws for connection, and other appropriate means). The wires can also be soldered. Clamps or glue can be used to properly route the wires to prevent sagging of the wires. The remote control unit, in the wired system, is the only wireless component.
[0029] The electromagnetic locking devices have an indicator light function to indicate connection, e.g. LEDs. The indication means provides an indication of the electromagnetic locking device's state (e.g. being in a locked or in an unlocked condition). The indication means can also be configured to provide a discrete signal that can be used to indicate the locked or unlocked condition of the electromagnetic locking device on the smart device.
[0030] The controller has a receiver that can accept instructions from the remote control unit or the smart device connected the controller. Based on the user's instructions/prompts, the controller then provides appropriate signals for facilitating either simultaneous locking/unlocking of the electromagnetic locking devices or locking/unlocking of any particular electromagnetic locking device.
[0031] The power and ground required from the operation of the electromagnetic locking devices is provided by the controller, which is operated via a batter pack or a supply from the main. It is to be noted that the electromagnetic locking devices are not constantly receiving positive current and are activated only after the controller receives a signal that requires the electromagnetic locking device to be locked or unlocked.
[0032] Different modes of operations can be configured and provided as options to the users. For example, child lock mode shall lock all the electromagnetic locking devices, whereas a guest mode can be used to keep the electromagnetic locking devices unlocked for a pre-determined time period.
[0033] In cases of system failure, an unlocking device can used to unlock the electromagnetic locking devices. Each electromagnetic device shall allow pre-determined movement of the locked elements, e.g., the door or the drawer to allow the insertion of the unlocking device for unlocking the same.
B. The Wireless System Embodiment
[0034] Substantially similar functionality to the above wired embodiment, except that the electromagnetic locking devices are wirelessly coupled to the controller. The electromagnetic locking devices are herein battery-operated. It is to be noted that the electromagnetic locking devices are not constantly activated and are activated only after the controller receives a particular signal that requires the electromagnetic locking device to be locked or unlocked.

Further Description of System HardwarePCB Board, RFID and Connectivity,
Including Alternate Embodiments
[0087] The electronic controller consists of a PCB board that has WiFi antenna. The PCB Board (printed circuit board) has a WiFi Antenna [and depending on the enclosure chosen for the application] the antenna is embedded in the PCB or it can be externally mounted for better signal. The PCB has capability to connect via Bluetooth as well.
[0088] The PCB Board receives electrical power from either wall outlet 120 V transformed to 5-12 DC voltage. When the signal is received from the app the PCB Board has internal relays that act as control relays that send out voltage out of the PCB into main contactors when the contactor is actuated it sends voltage to the predetermine door or drawer of preference.
[0089] There is a predetermined amount of time that is written within the System's App wherein the voltage will remove from the control relay, thus removing power from the voltage thus the latches will go into the lock up position when electrical power is removed because of a spring.
[0090] Another embodiment of how the linear electromagnetic actuator are utilized in the unlock position is they are powered unlocked when electrical power is removed a spring/magnet will return them to the lock position.
[0091] The PCB can be mounted inside a plastic, metal or hybrid enclosure (combined metal and plastic) the enclosure consists of PCB, wiring, BUS bars, main contactors.
[0092] The PCB has inputs for RFID readers on it that can unlock or provide power to the control relay which will provide power to the contactor.
[0093] The PCB utilizes an RFID port for wireless transmitter transmitting megahertz (MHz) from wireless remote control that will give the signal via the DOD1 input on the PCB for the RFID.
[0094] When the wireless remote is pressed, the control relays will be energized for a predetermined amount of time that is programmable.
[0095] The PCB has an input on it to connect a wired switch or push button one can use to unlock doors drawers for predetermined amount of time when electrical power will be removed.
[0096] The PCB has an input for an alarm, such that when the system is activated and the magnetic switch is utilized for the alarm if it doesn't sense the trigger that the door or drawer is closed, it will send a signal to a horn built into the PCB.
[0097] The PCB has a flashing light that serves as indicator light to indicate if it is connected to WiFi (802.11 or other applicable standards).
[0098] The PCB has the option of Ethernet LAN connection integrated in that the user can plug to the device to use the their internet instead of WiFi to connect to the App this could potentially be the case when a home is going under renovation or being built.
[0099] The number of contacts on PCB will depend on application: in baby proofing in a kitchen it may utilize a PCB with 8-10 control relays where a bathroom lower vanity may use only 1 control relay it all depends on the size.
[0100] The control relay provides power to contactor which can provide power to predetermine number of doors, drawers, cabinets, etc.
[0101] The electronic controller has a jack style connector for the voltage the voltage we use is low voltage DC.
[0102] This PCB has ability to use wireless remote control in addition to using the App. The PCB will also have a USB port to aid in configuration.
[0103] The enclosure has a power plug/adaptor female side and we just plug in the power to the adaptor. Depending on the application we may choose to utilize an internal power source.
[0104] As another embodiment of the installation, the System uses connectors that push and twist or push and lock with bus wires with positive and negative wires this wires are connected via heat shrink or tie wrap to ease installation and they are color-coded to ease installation. The System runs the wires down the length of the cabinet and the wire will be secured to the back behind the cabinet in some instances depending on access in some instances it will be secured under the counter which will be the preferred method for ease of installation they will be attached to a fastener, Velcro and secured with a screw when allowable.
[0105] Regarding the Linear Electromagnetic Actuator, electromagnets will be connected to the BUS wire with a T tap type of wire splicean instant splice that will not require cutting wires.
[0106] In this regard, the linear electromagnetic actuator and the latch will be screwed to the cabinet.
