Patent number: 11895588Abstract: Embodiments of the present disclosure provide systems and methods for maintaining timing precision in different operating modes of a device (e.g., a wireless node). A timing circuit may switch clock signals between two different modes (e.g., high power and low power) while preserving timing precision. In a high-power mode, the timing circuit may provide a high frequency clock signal, and in a lower-power mode, it may provide a low frequency clock signal. Moreover, the switching between the different clock signals may be synchronized to select edges of the low frequency clock signal.Type: GrantFiled: July 26, 2021Date of Patent: February 6, 2024Assignee: Analog Devices, Inc.Inventors: Brett Warneke, Gary Wayne Ng, Mark Alan Lemkin

Patent number: 10914789Abstract: A battery system monitor includes cell measurement circuits (CMCs) that each measure a voltage at or current through a pair of terminals of a respective associated battery module from among a plurality of plurality of battery modules in a battery system. Wireless communication transceivers (WCTs), each associated with a different CMC, transmit voltage or current measurement information of the associated CMC across a wireless communication link. A controller receives the voltage or current measurement information from the wireless communication transceivers for monitoring the state of operation of the battery system. Battery system monitoring is improved through synchronization of clocks in different CMCs or WCTs to enable synchronous sampling of multiple battery modules, through systems for determining relative positions of battery modules in a series coupling of battery modules between terminals of the battery system, and through improvements to the reliability of wireless communication.Type: GrantFiled: June 28, 2017Date of Patent: February 9, 2021Assignee: Analog Devices International Unlimited CompanyInventors: Mark Alan Lemkin, Alain Pierre Levesque, Brett Warneke, David McLean Dwelley, Erik Soule, Lance Robert Doherty, Gordon Alexander Charles, Thor Nelson Juneau, Jonathan Noah Simon, Robert Dobkin

Patent number: 10152111Abstract: A network device includes a network interface circuit, a microprocessor, a timing circuit, and a microsequencer. The timing circuit is configured to, based on a primary timing signal, generate a time signature and switch the network device from an inactive state to an active state when the time signature satisfies a predetermined threshold length of time for packet transmission. The microsequencer circuit is configured to, in response to the network device being switched to the active state, activate and configure the network interface circuit for the packet transmission, independent of the microprocessor and delays encountered by the microprocessor. The device also reduces energy consumption by using a lower frequency secondary oscillator to maintain timing information when a higher frequency primary oscillator is inactivated.Type: GrantFiled: October 9, 2017Date of Patent: December 11, 2018Assignee: Linear Technology CorporationInventors: Brett Warneke, Maxim Moiseev

Patent number: 9785219Abstract: A device reduces its energy consumption using a relatively lower frequency and lower power secondary oscillator to maintain timing information when a higher frequency and higher power primary oscillator is inactivated. The secondary oscillator maintains timing information at a higher resolution than the period of the oscillator, so as to conserve synchronization when the higher frequency, higher power primary oscillator is inactivated. In some embodiments, a microsequencer is programmably configured to control an integrated radio receiver and transmitter using less power than an associated microprocessor would use to perform the same functions. In other embodiments, flexible event timing facilitates the merging of wake-up events to reduce the energy consumed by wake-up operations in the device.Type: GrantFiled: October 27, 2014Date of Patent: October 10, 2017Assignee: Linear Technology CorporationInventor: Brett Warneke

Patent number: 6046659Abstract: Methods for the design and fabrication of micro-electro-mechanical switches are disclosed. Two different switch designs with three different switch fabrication techniques are presented for a total of six switch structures. Each switch has a multiple-layer armature with a suspended biasing electrode and a conducting transmission line affixed to the structural layer of the armature. A conducting dimple is connected to the conducting line to provide a reliable region of contact for the switch. The switch is fabricated using silicon nitride as the armature structural layer and silicon dioxide as the sacrificial layer supporting the armature during fabrication. Hydrofluoric acid is used to remove the silicon dioxide layer with post-processing in a critical point dryer to increase yield.Type: GrantFiled: May 15, 1998Date of Patent: April 4, 2000Assignees: Hughes Electronics Corporation, Rosemont Aerospace, Inc.Inventors: Robert Y.

Patent number: 6043727Abstract: A reconfigurable filter system designed using micro-elecro-mechanical (MEM) switches is disclosed. The filter comprises a transmission line with one or more filter stubs coupled to the transmission line by MEM switches. The impedance of the filter system is altered by selectively opening and closing the MEM switches, which alters the filter characteristics of the filter system. Alternatively, the characteristics of the filter system are altered by using the MEM switches to selectively alter the length of filter stubs attached to the transmission line.Type: GrantFiled: May 15, 1998Date of Patent: March 28, 2000Assignee: Hughes Electronics CorporationInventors: Brett Warneke, Juan Lam, Adele Schmitz, Julia Brown, Darren Atkinson, Daniel J.
