Abstract: A locomotive has DC or AC traction motors, powered by a hydrogen fuel cell, and optionally other sources such as regenerative braking. The traction motors of the locomotive may be connected to a set of independent DC choppers or AC inverters, linked via a common DC bus, configured to regulate power from the one or more power sources. A manager module, among other functions, may receive inputs and signals to coordinate delivery of electricity from the sources to the motor. A method for retrofitting a legacy locomotive may include removing a generator and a control apparatus configured for diesel fuel, and installing a kit of apparatus configured to be powered by a hydrogen fuel cell. A railway system for use by locomotives powered by hydrogen has one or more hydrogen-generation stations deployed near a track of the railway system.

Abstract: A stop to barricade a door from forced entry. The stop includes an upper portion designed to contact the door to barricade it against forced entry, and a lower portion that fits within a receptacle that is recessed into the floor. The stop can be removed from the receptacle when the user doesn't desire to barricade the door. When the stop is placed in the receptacle, the stop is preferably configurable by the user in two modes: a first that allows the user to slightly open the door by a gap, and a second that barricades the door when it is shut. Barricading the door in this second mode is beneficial because it allows the user to look through the gap to verify the identity of a person on the outside of the door, and/or to receive an item through the gap while not opening the door completely.

Abstract: A system to barricade a door from forced entry is disclosed. The system includes an anchor insertable by a user into a receptacle mounted into a floor on the inside on the door, and a lock affixable to the door. The anchor includes an upper portion designed to connect with the lock, and a lower portion that preferably fits within the receptacle. The lock includes a stop designed to contact the outside surface of the door, and a key plate on the inside of the door. When the anchor is vertically inserted into the receptacle, the upper portion of the anchor engages the key plate of the lock affixed to the door, which in conjunction with the stop prevents the door from swinging outwards. The anchor can be removed from the receptacle when the user doesn't desire to barricade the door.

Abstract: A server system includes a first plurality of mass-storage devices, a central processing unit (CPU), and at least one near data processing (NDP) engine. The CPU is coupled to the first plurality of the mass-storage devices, such as solid-state drive (SSD) devices, and the at least one NDP engine is associated with a second plurality of the mass-storage devices and interposed between the CPU and the second plurality of the mass-storage devices associated with the NDP engine. The second plurality of the mass-storage devices is less than or equal to the first plurality of the mass-storage devices. A number of NDP engines may be based on a minimum bandwidth of a bandwidth associated with the CPU, a bandwidth associated with a network, a bandwidth associated with the communication fabric and a bandwidth associated with all NDP engines divided by a bandwidth associated with a single NDP engine.

Abstract: A method for providing toxin information and recommendations includes receiving toxin content data for at least one ingredient. The toxin content data may include the type and amount for toxins found in the ingredient. The ingredient is classified based on the toxin content data and a predetermined allowable toxin amount for the ingredient. Based on the classification of the ingredient, ingredient storage information is displayed. In addition, ingredient use information may be displayed based on the toxin content data.

Abstract: The golf cart signal flag system comprises a base which engages golf cart structure and which mounts thereto a chosen plurality of pivotable signal flags, each of which is identifiable as indicating a particular need, want or condition of players on the course to golf course personnel and/or other players. One or more flags may be raised simultaneously. If desired, the system may be created as part of a roof of a golf cart.

Abstract: A diaphragm valve is described, which has a valve body having disposed within it an upper chamber and a lower chamber. The valve body also has first and second connection members that extend from the valve body at substantially a right angle, and where the connection members are hollow and in fluid communication with the upper chamber of the valve body. The valve comprises: an entrance for admitting a fluid, an exit for passage of the fluid when the fluid is flowing, a draining port for draining of the fluid from the valve, and a passage between the entrance, the exit, and the draining port; wherein the passage is shaped to permit complete draining of the fluid from the valve under force of gravity when the draining port is open.
