Publication number: 20180319608Abstract: A rail-road intermodal freight system. In an embodiment, a conveyor system is provided for placing rail cars in a position for loading shipping containers thereon, while an over-the-road trailer is secured to the rail car. Rail cars have a frame with a front end and a rear end, and a bogie having at least four flanged rail wheels is pivotally mounted to the rear of the frame of the rail car. A method for unloading the rail cars includes lifting the front of the frame of the rail cars and pivoting the rail cars by an angle alpha from the track direction at an unloading area, and lowering the front end of the frame to the ground to allow truck access to trailers on the rail car. By utilizing the method, efficient loading and unloading of train involved in intermodal shipments may save considerable time, and thus reduce costs.Type: ApplicationFiled: July 5, 2018Publication date: November 8, 2018Applicant: SEA-TRAIN EXPRESS - LLCInventor: David KUN

Patent number: 9096239Abstract: A rail-road intermodal freight system. In an embodiment, a plurality of L-cars are provided. In an embodiment, each L-car may be configured for support at its forward end on a preceding L-car, and at a rear base on a set of flanged rail wheels. In implementing the system, a freight yard is provided with rail components which are switchable to enable decoupling and a turn-in-place operation, wherein each care is lifted from the preceding L-car in the train, and the neck portion of the L-car lowered to the ground. When in the lowered position, downwardly extending legs on the over-the-road trailer enable an over-the-road tractor to attach the over-the-road trailer in conventional fashion, for removal of the over-the-road tailer from the L-car. Loading of an over-the-road trailer on the L-car takes place via a reverse process, wherein the trailer is backed up on to the L-car.Type: GrantFiled: July 23, 2014Date of Patent: August 4, 2015Inventor: David Kun

Patent number: 8352754Abstract: In a communications system, such as a Power-Over-Ethernet system, where power supply equipment (PSE) supplies power to powered requiring devices (PRDs), a system and method of dynamic power management is implemented. The system and method monitors the power consumed at each port by the PRDs. Based on this monitoring, the PSE dynamically determines the minimum power which can be allocated to each PRD, and so dynamically maximizes the available reserve power. The PSE maintains a queue or queues wherein PRDs are listed in order of a power allocation priority. When additional power is available, the PSE preferentially allocates power to a PRD or PRDs which have higher priority. The system and method of the present invention minimizes the power allocated to each individual network device, as a result of which the total number of network devices that can be supported with the available power may be maximized.Type: GrantFiled: November 9, 2007Date of Patent: January 8, 2013Assignee: Broadcom CorporationInventor: David Kun Chin
