Patent number: 11765417Abstract: At least one aspect of the present disclosure is directed to systems and methods of selecting and acknowledging content to broadcast. A system can receive, at a first time, a request for content to broadcast identifying a content publisher. The system can obtain cluster data of the content publisher corresponding to a first time, the cluster data identifying content selection metrics based on predicted characteristics of the cluster corresponding to the first time. The system can determine a subset of content items having cluster filtering criteria that satisfy the content selection metrics. The system can rank the subset of content items based on the content selection metrics to create an ordered list of content items. The system can transmit data identifying the order of the content items to the content publisher. The content publisher can insert the content into a broadcast in the order identified by the system.Type: GrantFiled: April 8, 2020Date of Patent: September 19, 2023Assignee: GOOGLE LLCInventors: Charles Alexander Solarski, David Andrew Brown, Stella Loh, Akshay Lal, Tyrone Hidekazu Nakahara

Patent number: 10883242Abstract: A double-acting hydraulic impact hammer includes a drop weight and an inner hydraulic piston. The drop weight is arranged to be driven in an upward and downward direction and the drop weight acts on a pile during its downward motion. The piston has a voided internal area defining a piston volume which is arranged to receive a piston rod and along which the piston extends and retracts axially. The piston volume is in sealed hydraulic communication with the hollow rod volume to form a first volume which changes size as the piston moves along the piston rod whereby the application of hydraulic pressure to the first volume biases the piston towards its extended position. The hammer includes a bore and a collar. The collar forms an outer piston having a working surface which when exposed to hydraulic fluid has sufficient surface area to lift the piston and the drop weight.Type: GrantFiled: June 29, 2017Date of Patent: January 5, 2021Assignee: DAWSON CONSTRUCTION PLANT LIMITEDInventors: Stephen Desborough, David Andrew Brown

Publication number: 20190265698Abstract: Systems and methods for tele-present recovery of self-driving vehicles are disclosed. The system comprises one or more self-driving vehicles, a server, and a master-assistance device. The vehicle operates in a full-autonomous mode until a problem is encountered, triggering a vehicle status associated with a master-assisted intervention. A master-assisted intervention request and associated environment state information are sent from the server to the master-assistance device. A human operator of the master-assisted intervention device provides input indicative of operational commands for the vehicle. The operational commands are received by the vehicle, and the vehicle is operated in a semi-autonomous mode based on the operational commands. When the problem has been resolved, an assistance complete message is sent to the vehicle, and the vehicle returns to operating in the full-autonomous mode.Type: ApplicationFiled: February 28, 2019Publication date: August 29, 2019Inventors: Anthony William TOD, David Andrew BROWN, Ryan Christopher GARIEPY, Matthew Allen RENDALL
