Patent number: 10933208Abstract: A hollow extension tube or extension assembly aids in increasing the quantity of any inhaled or aerosolized substance delivered to a patient's lungs from an inhaler or source. The length of the extension tube reduces the velocity and increases the temperature of the aerosolized substance, easing inhalation. The interior surface of the hollow extension tube has anti-static properties which reduces the amount of aerosolized substance trapped by the interior surface of the hollow extension tube. The interior surface of the extension tube may be formed of cardboard.Type: GrantFiled: November 14, 2016Date of Patent: March 2, 2021Inventors: Vandana M. Krishna, Sampath Krishna, Neal S. Krishna, Ryan N. Krishna

Patent number: 7853218Abstract: A method of checking messages from a network of communication sources includes initially testing the signal strength of a plurality of communication sources, storing the identity of the communication sources with the two strongest signals, and alternatively entering a sleep mode and a wake-up mode, the wake-up mode synchronized to the communication source with the strongest signal. The method further includes testing the signal strength of one additional communication source, switching synchronization to the additional communication source if said source presents a signal stronger than the signal of a stored communication source with the strongest signal, and replacing the identity of any stored communication source if an additional communication sources tested in sequence presents a signal stronger than the signal of said stored communication source.Type: GrantFiled: August 12, 2009Date of Patent: December 14, 2010Assignee: Lojack Operating Company, LPInventors: Frank Romano, Sampath Krishna, Son Nguyen, Jesse Rhodes, Philip Grahame Crewe, Daniel Jonathan Finchley Cletheroe, Mark Marsden, Steven Walter Greendale, Nigel James Watson, Ian Christopher Stroud, Timothy David Howe, Gerard Edward Smith

Patent number: 7593711Abstract: A vehicle locating unit with improved power management. A receiver receives a signal from a network of communication sources. A signal strength monitoring subsystem determines which of the communication sources are transmitting the strongest signals. A power management subsystem is responsive to the signal strength monitoring subsystem and is configured to alternatively enter sleep and wake-up modes, synchronize the wake-up mode to the communication source transmitting the strongest signal, and test the signal strength of at least one additional communication source according to a predefined sequence.Type: GrantFiled: May 18, 2005Date of Patent: September 22, 2009Assignee: LoJack Operating Company, LPInventors: Frank Romano, Sampath Krishna, Son Nguyen, Jesse Rhodes, Philip Grahame Crewe, Daniel Jonathan Finchley Cletheroe, Mark Marsden, Steven Walter Greendale, Nigel James Watson, Ian Christopher Stroud, Timothy David Howe, Gerard Edward Smith

Publication number: 20070040668Abstract: A recovery system including a station and a plurality of remote transmitting units linked to the station. Each remote transmitting unit includes a transmitter, a receiver, and a controller configured to periodically send a message via the transmitter. The controller receives, via the receiver, that same message from at least one other remote transmitting unit. The controller then provides a notification to the station when the message has not been received in a predetermined time period.Type: ApplicationFiled: August 18, 2005Publication date: February 22, 2007Inventors: Sampath Krishna, James Justice, George Liu
