Publication number: 20220181707Abstract: A retrofit module for lithium battery passivation, detection, activation and maintenance (PDAM) may include a test circuit, a load circuit, a microcontroller and means for electrically connecting the PDAM module to a target battery in a device. Upon power-up and/or joining or rejoining a network, and additionally at periodic intervals thereafter, the state of the target battery is determined and an activation algorithm is executed, the parameters of which are dependent upon the determined target battery state.Type: ApplicationFiled: March 6, 2019Publication date: June 9, 2022Inventors: Robert Reginald Albert FELTHAM, Martin A. CHIARIZIO, Andreas BRENNER

Patent number: 11245136Abstract: A method of depassivating a battery may include receiving a determined state of the battery and applying, depending on the determined state, a depassivation algorithm to the battery. The algorithm may include applying a load across the battery for a predetermined amount of time that is dependent on the degree of battery passivation.Type: GrantFiled: October 11, 2019Date of Patent: February 8, 2022Assignee: JOHNSON CONTROLS FIRE PROTECTION LPInventors: Martin A. Chiarizio, Robert Reginald Albert Feltham, Vyacheslav Voloshin

Patent number: 11112460Abstract: A method for determining lithium battery passivation starts by applying a load across a lithium battery at the start of a test interval. Measurements of the battery's voltage are taken after applying the load, and then again periodically during the test interval. A final measurement of the battery's voltage at the end of the test interval. The state of the battery is then determined based on the first and final measurements, and at least one of the periodic measurements.Type: GrantFiled: October 11, 2019Date of Patent: September 7, 2021Assignee: JOHNSON CONTROLS FIRE PROTECTION LPInventors: Robert Reginald Albert Feltham, Martin A.

Patent number: 10966154Abstract: A wireless fire alarm notification system uses wireless repeater devices to annunciate an alarm to slave devices from the control panel. A notification device provides a local synchronization signal via wire to a secondary notification device. A method enables the activation or deactivation of child device without the child device having to query their parent repeater. A circuit to test the integrity of an active battery charger, a battery, and an isolation circuit is also shown. A method for qualifying that an RF signal meets a specified minimum acceptable level is described. A method for wirelessly sending events to avoid RF link overload is provided. A programming checksum method confirms that an annunciator has latest programming information. A method to automatically process messages from new devices without having to hardcode repeaters to support these new devices is also described.Type: GrantFiled: October 3, 2019Date of Patent: March 30, 2021Assignee: Johnson Controls Fire Protection LPInventors: Martin A.

Patent number: 10764810Abstract: A system includes a wireless communication device that joins a wireless communication network. Specifically, the wireless communication device measures a quality metric of the wireless communication network in response to a trigger to join the wireless communication network. The wireless communication device determines whether the quality metric indicates a high quality environment or a low quality environment for communicating signals. In response to the quality metric indicating the high quality environment, the wireless communication device selects a first pathway with an optimum transmission time between the wireless communication device and a central controller of the wireless communication network. In response to the quality metric indicating a low quality environment, the wireless communication device selects a second pathway comprising an optimum quality link between the wireless communication device and another wireless communication device in the wireless communication network.Type: GrantFiled: March 25, 2019Date of Patent: September 1, 2020Assignee: JOHNSON CONTROLS FIRE PROTECTION LPInventors: Martin A.

Patent number: 10555262Abstract: Monitoring and mass notification systems, such as fire alarm systems, for use in occupied structures, and more particularly to wireless monitoring and mass notification systems include wireless base units that can be modular in design. This allows horns, mini horns, strobes, and audio messaging modules (e.g., speakers) to be physically plugged into the wireless base unit creating a unit with the appearance of a single physical unit. Preferably standardized plugs are used. In some cases, visual and audio modules (i.e., notification devices) have their own battery pack or external power interface. Each wireless base unit can optionally function as a repeater if it has dual transceivers (master transceiver and slave transceiver).Type: GrantFiled: June 29, 2017Date of Patent: February 4, 2020Assignee: Johnson Controls Fire Protection LPInventors: Martin A.

Patent number: 10078943Abstract: Method for synchronizing a non-symmetrical tonal pattern in a wireless alerting system involves receiving at a plurality of alerting devices a beacon message. The beacon message is used at the alerting devices to synchronously generate a synchronization pulse signal comprised of a plurality of synchronization pulses which are periodic in accordance with a predetermined synchronization pulse interval. A cadence section indicator (CSI) in the beacon message is used in combination with the synchronization pulse signal to determine a portion of an alarm cadence to sound at each of the alerting device so that the alarm cadence is synchronized among the plurality of the alerting devices.Type: GrantFiled: November 8, 2016Date of Patent: September 18, 2018Assignee: Tyco Fire & Security GmbHInventors: Robert Feltham, Martin Chiarizio
