Patent number: 12195354Abstract: A stormwater capture housing system is designed to reduce greenhouse gas emissions by filtering solid waste from stormwater flow in roadways, transportation facilities, and pavement, while maintaining an optimal flow rate and enabling safe accessibility with minimal to no impact due to animal entrapment. The system comprises a housing unit with surface grates that enable stormwater and solid waste to drain from the roadway into a sub-grade capture area formed by a screen weir and a screen box, including a wildlife escape structure in the capture area that provides a pathway out of the unit. The screen box collects solid waste while filtering water into a clean water area. The screen weir filters solid waste while allowing for overflow. There is a filled grating configuration at the top surface that allows for stormwater to drain, also enabling access to the internal components of the housing system.Type: GrantFiled: May 29, 2023Date of Patent: January 14, 2025Assignee: State of California, Department of TransportationInventor: Cornelis M. Hakim

Patent number: 11535528Abstract: A stormwater capture housing system designed to reduce greenhouse gas emissions by filtering solid waste from stormwater flow in roadways, transportation facilities, and pavement, while maintaining an optimal flow rate and enabling safe accessibility. The system comprises a housing unit with top grates that enable stormwater and solid waste to drain from the roadway into a sub-grade capture area formed by a screen weir and a screen box. The screen box ensures that the solid waste is collected while the water filters into a clean water area. The screen weir also filters solid waste and is further configured to allow for an overflow of stormwater and solid waste. Another section of the top wall has a filled grating configuration that allows for stormwater to drain without passing any solid waste to prevent flooding, also enabling access to the internal components of the housing system.Type: GrantFiled: August 25, 2022Date of Patent: December 27, 2022Assignee: State of California, Department of TransportationInventor: Cornelis M.

Patent number: 7410321Abstract: A mobile work zone protection device includes a front carrier, a barrier beam assembly, and a rear carrier. In one embodiment, the barrier beam assembly includes two sets of telescoping beam structures. Each of these structures can rotate from one side of the device to the other, and thus can be deployed to create a safe work zone for roadway workers on either side of the device. The structure can also be left in the transit position to provide an enclosed safe work zone.Type: GrantFiled: October 24, 2006Date of Patent: August 12, 2008Assignee: State of California Department of TransportationInventors: Calvin W. Schiefferly, Angela E. Wheeler, Jeremy M. Matsuo

Patent number: 7175893Abstract: A corrosion protection covering method for spliced regions of reinforcing steel is disclosed. The covering may include an outer, heat shrinkable layer and a flowable inner layer. The covering is applied to the spliced region, and then heated, causing the outer layer to constrict and thereby seal the taped area. The heat also causes the inner layer to liquify and fill any voids.Type: GrantFiled: May 13, 2004Date of Patent: February 13, 2007Assignee: State of California, Department of TransportationInventors: Deane M. Coats, Robert A. Reis

Patent number: 7126875Abstract: An underwater energy dampening device is disclosed. This device includes a plurality of vertically-spaced bubble producing units. With bubbles produced at various depths, the present invention can effectively attenuate sound and other energy from underwater construction projects in high current or deep water areas.Type: GrantFiled: October 20, 2003Date of Patent: October 24, 2006Assignee: State of California, Department of TransportationInventors: Andrew J. Baskerville, David D. Ambuehl

Patent number: 6808339Abstract: A modular retaining watt has tiers of headers which extend into compacted backfill material and tiers of stretchers which extend between headers to form the front face of the wall. Vertical pins, extending between successive headers in each stack of headers, facilitate precise emplacement of headers during construction of the wall. Layers of geosynthetic mesh reinforcement reinforce the load bearing capability of the backfill. Load forces in the backfill are sustained by forward ends of the layers of geosynthetic mesh reinforcement, which extend upward in front of the backfill and then backward into the backfill, instead of being sustained by the stretchers. A sizable space behind the stretchers may be filled with loose topsoil to facilitate growth of landscaping plantings on the face of the wall.Type: GrantFiled: August 23, 2002Date of Patent: October 26, 2004Assignee: State of California Department of TransportationInventors: John E. Peterson, Deh-Jeng Jang

Patent number: 4623289Abstract: A device for holding a wheelchair stationary on a floor has a pair of notched plates at their rearward ends adapted to abut a transverse barrier upstanding from the floor and to be releasably engaged at their forward ends by a bail fastened to and swinging from the floor to engage the forward ends of the notched plates with sufficient resilient force to lock the wheelchair in position.Type: GrantFiled: November 20, 1984Date of Patent: November 18, 1986Assignee: State of California, Department of TransportationInventor: John A. Apostolos

Patent number: 4506485Abstract: Electrically conductive metal is melted, preferably by a flame, and is sprayed onto a freshly exposed, pitted surface of a concrete member having iron embedded therein. The sprayed metal, when cooled, forms a metal cover on and interlocked with at least part of the newly exposed surface. The cover and the embedded iron are preferably joined in an electric circuit affording a direct current electromotive force, effectively opposite to that which normally would occur, in order to preclude the deterioration of the contained iron.Type: GrantFiled: April 12, 1983Date of Patent: March 26, 1985Assignee: State of California, Department of TransportationInventor: John A. Apostolos
