  • Patent number: 10868443
    Abstract: An inductive wireless power system using an array of coils with the ability to dynamically select which coils are energized. The coil array can determine the position of and provide power to one or more portable electronic devices positioned on the charging surface. The coils in the array may be connected with series resonant capacitors so that regardless of the number of coils selected, the resonance point is generally maintained. The coil array can provide spatial freedom, decrease power delivered to parasitic loads, and increase power transfer efficiency to the portable electronic devices.

  • Publication number: 20200290014
    Abstract: A method for preparing a nano-enabled activated carbon block, a nano-enabled activated carbon block produced by the method, a household water filtration system comprising the nano-enabled activated carbon block, and a method for filtering tap water using the household water filtration system are provided. The method includes contacting a solution including a metal(lic) precursor (e.g. a titanium compound and/or an iron compound and/or a zirconium compound) with activated carbon particles such that the solution fills pores of the activated carbon particles. The method further includes causing a metal (hydr)oxide (e.g. titanium dioxide and/or zirconium dioxide and/or iron oxide) to precipitate from the solution thereby causing metal oxide nanoparticles to become deposited within pores of the activated carbon particles. The method also includes preparing a nano-enabled activated carbon block from the activated carbon particles having metal oxide nanoparticles deposited within the pores thereof.

  • Patent number: 10530188
    Abstract: A remote device in accordance with the present invention includes an adaptive power receiver that receives wireless power from the wireless power supply by induction. The adaptive power receiver may be switched among two or more modes of operation, including, for example, a high-Q mode and a low-Q mode. By controlling the switching between modes, the amount of energy received by the adaptive receiver may be controlled. This control is a form of adaptive resonance control or Q control.

  • Publication number: 20190288560
    Abstract: An inductive power supply system to identify remote devices using unique identification frequencies. The system includes an AIPS and a tank circuit capable of inductively providing power to a remote device at different frequencies, and a sensor for sensing the reflected impedance of the remote device at tank circuit. The system further includes a plurality of different remote devices, each having a unique resonance frequency. In operation, the AIPS is capable of identifying the type of remote device present in the inductive field by applying power to a remote device at a plurality of unique identification frequencies until the remote device establishes resonance in response to one of the identification frequencies. The AIPS includes a controller that recognizes when resonance has been established by evaluating sensor data, which is representative of the reflected impedance of the remote device.

  • Patent number: 10198892
    Abstract: A system is disclosed for charging or billing for access to wireless power. The device requiring power communicates with the power provider and the billing method is determined. A consumer may be required to provide billing information, or if the billing information is already associated with an existing account, the consumer account is automatically charged for the wireless power. The account may include prepaid charging minutes that are debited as wireless power is provided, or the account may be billed for the wireless power that is provided. The charging/billing for the wireless power may be used to receive value for the power that is provided, while remaining consumer friendly.

  • Patent number: 10170935
    Abstract: An inductive power supply that maintains resonance and adjusts duty cycle based on feedback from a secondary circuit. A controller, driver circuit and switching circuit cooperate to generate an AC signal at a selected operating frequency and duty cycle. The AC signal is applied to the tank circuit to create an inductive field for powering the secondary. The secondary communicates feedback about the received power back to the primary controller. The power transfer efficiency may be optimized by maintaining the operating frequency substantially at resonance, and the amount of power transferred may be controlled by adjusting the duty cycle.

  • Patent number: 10014722
    Abstract: A ballast circuit is disclosed for inductively providing power to a load. The ballast circuit includes an oscillator, a driver, a switching circuit, a resonant tank circuit and a current sensing circuit. The current sensing circuit provides a current feedback signal to the oscillator that is representative of the current in the resonant tank circuit. The current feedback signal drives the frequency of the ballast circuit causing the ballast circuit to seek resonance. The ballast circuit preferably includes a current limit circuit that is inductively coupled to the resonant tank circuit. The current limit circuit disables the ballast circuit when the current in the ballast circuit exceeds a predetermined threshold or falls outside a predetermined range.

  • Patent number: 9597261
    Abstract: A pill dispensing system that includes pill packages that can be used to dispense pills manually or with a dispenser system to provide enhanced functionality. The packages can be provided with information relating to the packaged pills or to the use of the packaged pills. By reading the information from the package, the dispenser system can know what is in the package, when it is to be taken and can understand and track inventory. The dispenser system provides reminders of when the pills should be taken. The dispenser system may have the ability to key a specific electronic device, such as a cell phone, to a specific user and the dispenser system may require the electronic device to be within proximity of the dispenser system before dispensing pills for that user.
