Patent number: 10976377Abstract: A device may include a wire interface (e.g., port), a detection circuit and a microcontroller. The detection circuit may include a resistor, a comparator, and wiring connecting the resistor to the wire interface and to a first input of the comparator. The microcontroller may provide a test signal to the resistor, and a threshold signal to a second input of the comparator. The test signal passes through the resistor and continues to the wire connector and the comparator first input with little to no change or attenuation when the wire interface is disconnected, but is attenuated when the wire interface is connected to a wire with capacitance charging and discharging based on the test signal. The comparator may compare the voltage of a resulting signal at the wire interface to the threshold signal voltage, and depending on the comparison may detect if a wire is connected to the wire interface.Type: GrantFiled: August 14, 2019Date of Patent: April 13, 2021Assignee: OPENPATH SECURITY INC.Inventors: Michael Biggs, Samy Kamkar, Alexander A.

Patent number: 10445956Abstract: Secure handsfree two-stage access control is provided via a first stage that is performed when a mobile device is within a first distance from an access control reader, and a second stage that is performed when the mobile device is within a second distance from the reader, wherein the second distance is less than the first distance. Performing the first stage includes establishing a secure connection between the mobile device and the reader, and authorizing access for the mobile device to a secured resource. Performing the second stage includes providing access to the secured resource when the mobile device has been authorized to access the secured resource during the first stage, and the mobile device enters within the second distance from the reader. The second stage may be triggered in response to the reader detecting a user gesture or action.Type: GrantFiled: August 20, 2018Date of Patent: October 15, 2019Assignee: OPENPATH SECURITY INC.Inventors: Samy Kamkar, Jacqueline Mak, Cameron Kaye, Michael Biggs

Publication number: 20180360597Abstract: A automatic variable frequency electrolarynx with a microcontroller that generates a random but controlled frequency that creates a random tone. The controlled random tone allows the user of the electrolarynx to use the device without the monotone of standard electrolarynx. The electrolarynx also includes an encoder that allows the user to easily adjust the base tone of the device. The electrolarynx also includes an integrated LED light in the on/off switch to indicate whether the encoder is in volume control or tone control mode. The microcontroller also conducts an automatic power source check, and produces a musical tone when the battery is low.Type: ApplicationFiled: May 12, 2017Publication date: December 20, 2018Applicant: Archer Medical Devices LLCInventors: Michael Biggs, Matthew Griffin

Patent number: 9033976Abstract: This relates to treating reversible chronic obstructive pulmonary disease, and more particularly, to exchanging energy with airway tissue such as that found in human lungs. This exchange of energy reduces the ability of the airways to constrict, reduces the resistance within the airway to the flow of air through the airway, reduces mucus plugging of the airways, and/or increases the airway diameter. This energy exchange also may reduce the ability of the lung to produce at least one of the symptoms of reversible obstructive pulmonary disease.Type: GrantFiled: May 16, 2013Date of Patent: May 19, 2015Assignee: Asthmatx, Inc.Inventors: Christopher J.

Patent number: 8888769Abstract: The present invention includes a system for delivering energy to an airway wall of a lung comprising an energy delivering apparatus and a PID controller having one or more variable gain factors which are rest after energy deliver has begun. The energy delivering apparatus may include a flexible elongated member and a distal expandable basket having at least one electrode for transferring energy to the airway wall and at least one temperature sensor for measuring temperature. The PID controller determines a new power set point base on an error between a preset temperature and the measured temperature. The algorithm can be Pi+1=Pi+G(?ei+?ei?1+?ei?2) where ?, ? and ? are preset values and ? is from 1 to 2; ? is from ?1 to ?2; and ? is from ?0.5 to 0.5. In another variation, the controller is configured to shut down if various measured parameters are exceeded such as, for example, energy, impedance, temperature, temperature differences, activation time and combinations thereof.Type: GrantFiled: November 11, 2010Date of Patent: November 18, 2014Assignee: Asthmatx, Inc.Inventors: Michael Biggs, Roger A.
