Patent number: 11920351Abstract: A vent is disclosed that is particularly suited to use in ventilating attic spaces beneath a hip roof. The vent is configured to be installed along a hip of the roof overlying and covering a ventilation slot formed through the roof deck along the hip. The vent includes an elongated laterally flexible top panel from which baffle arrays depend. The baffle arrays are formed of a plurality of depending arcuately curved vanes that arc away from the vent. The vanes are aerodynamically shaped to redirect wind-blown rain and snow away from the vent and are configured to block the migration of rain and snow through the vent. A pair of spongy conformable filler strips is attached beneath the edge portions of the vent. The filler strips conform to the shapes of underlying shingles when the vent is installed to fill any gaps that otherwise might be formed between the vent and the shingles.Type: GrantFiled: August 26, 2022Date of Patent: March 5, 2024Assignee: BMIC LLCInventors: Tim Manasterski, Walter R. Zarate, Sudhir S. Railkar, Jeffrey Avitabile, Peter Campbell

Publication number: 20220128681Abstract: A method is provided that involves identifying a target region of an environment of an autonomous vehicle to be monitored for presence of moving objects. The method also involves operating a first sensor to obtain a scan of a portion of the environment that includes at least a portion of the target region and an intermediate region between the autonomous vehicle and the target region. The method also involves determining whether a second sensor has a sufficiently clear view of the target region based on at least the scan obtained by the first sensor. The method also involves operating the second sensor to monitor the target region for presence of moving objects based on at least a determination that the second sensor has a sufficiently clear view of the target region. Also provided is an autonomous vehicle configured to perform the method.Type: ApplicationFiled: January 7, 2022Publication date: April 28, 2022Inventors: Brandon Douglas Luders, Tim Campbell, Nathaniel Fairfield

Patent number: 9841498Abstract: Disclosed herein are embodiments that relate to phase coded linear frequency modulation for a radar system. Embodiments include transmitting at least two signal pulses. The transmitting includes transmitting a first pulse with a first phase modulation and a first chip rate, and transmitting a second pulse with a second phase modulation and a second chip rate. The second chip rate may be different than the first chip rate. Embodiments also include receiving a signal that includes at least two reflection signals associated with reflection of the at least two transmitted signal pulses. Embodiments further include processing the received signal to determine target information. The processing includes filtering the received signal to time-align the at least two reflection signals. The filtering includes applying a frequency-dependent time delay to one or more of the at least two reflection signals. Additionally, embodiments include removing phase code modulations from the time-aligned reflection signals.Type: GrantFiled: November 20, 2014Date of Patent: December 12, 2017Assignee: Waymo LLCInventors: Tim Campbell, Russell Leigh Smith

Patent number: 8945245Abstract: A method is provided in which pretreated and densified cellulosic biomass particulates can be hydrolyzed at a high solids loading rate as compared with the solids loading rate of loose hydrolysable cellulosic biomass fibers. The resulting high concentration sugar-containing stream can be easily converted to biofuels or an entire suite of other useful bioproducts.Type: GrantFiled: April 27, 2012Date of Patent: February 3, 2015Assignees: The Michigan Biotechnology Institute, Board of Trustees of Michigan State UniversityInventors: Bryan Bals, Farzaneh Teymouri, Tim Campbell, Bruce Dale

Patent number: 8949827Abstract: A method and system provide tracking of a virtual machine by compiling information on the virtual machines in a network and sending the information to an administrative console. The administrative console can then determine the status of the virtual machines in the network. The administrative console can also establish a lineage of a virtual machine and the migration of a virtual machine from one host machine to another host machine. A virtual machine unique identifier assigned to each virtual machine by the system can be modified and used to track each virtual machine and associated host machine. A status can then be determined of the virtual machines, where the status can be a new virtual machine, a previously discovered virtual machine, a duplicated virtual machine, or a cloned virtual machine.Type: GrantFiled: January 11, 2008Date of Patent: February 3, 2015Assignee: Red Hat, Inc.Inventors: Daniel Lee Becker, Andrew W. Brandt, Vipul Sharma, Mark James Yourcheck, Stephen C. Carr, Tim Campbell

Patent number: 5852612Abstract: An arrangement (apparatus and method) for obtaining a single copy of a received signal from a simulcast broadcast area. Within a desired service area, multiple transmitters at separately located sites simultaneously broadcast the same multi-channel, multi-program signal. Broadcast waves from the transmitters propagate throughout substantially overlapping portions of the service area. Each such channel carries a multiplexed digital data stream containing packets of information for a plurality of programs, e.g. television programs. A receiver system comprises an antenna adapted to receive direct transmissions from two or more of the transmitters as well as multipath signals from two or more of the transmitters. To compensate for the potentially interfering signal receptions, the terminal device includes a delay processor, such as an adaptive delay equalizer or a rake receiver.Type: GrantFiled: November 9, 1995Date of Patent: December 22, 1998Assignee: Bell Atlantic Network Services, Inc.Inventors: Bruce Kostreski, Allan Schneider, Kamran Sistanizadeh, W.

Patent number: 5646942Abstract: Within a desired service area, multiple transmitters at separately located sites simultaneously broadcast the same multi-channel, multi-program signal. Broadcast waves from the transmitters propagate throughout substantially overlapping portions of the service area. Obstructions in the service area, e.g. mountains, buildings, trees, etc., may block reception from one or more of the transmitters at certain sites. However, at most receiving sites, the receiving antenna can receive a clear line-of-sight transmission from at least one and often two or more of the transmitters. Each broadcast channel carries a multiplexed digital data stream containing packets of information for a plurality of programs, e.g. television programs. A shared antenna system, typically including multiple receiving antennae aimed at a plurality of the transmitters, supplies received signals to terminals in a plurality of living units.Type: GrantFiled: March 24, 1995Date of Patent: July 8, 1997Assignee: Bell Atlantic Network Services, Inc.Inventors: Brian D.
