摘要： A mower blade assembly attaches to a rotatable spindle and includes a mounting plate which defines a first pin aperture. The mounting plate and a retaining plate are attached to the rotatable spindle. The retaining plate defines a second pin aperture. A movable pin plate comprises a pin. A blade is selectively attachable to the mounting plate. The blade defines a retaining plate aperture and a third pin aperture. A biasing member urges the movable pin plate from a disengaged position to an engaged position. The pin is engageable with the pin apertures for mounting and retaining the cutting blade to the mounting plate. The blade is attached by moving the blade over the retaining plate aperture, urging the movable pin plate to the disengaged position, rotating the blade, and releasing the movable pin plate. Another embodiment includes a force finger.

摘要： The disclosed technology relates to a method and system for localizing and confining an autonomous mobile work system or systems for performing work in a user defined space. The system can include two or more variable reflective base stations at first and second locations that can modify their optical or electromagnetic reflectivity based upon either an external command via wired or wireless communications interface, or automatically on a regular or asynchronous time schedule under programmed or user settable control. The system also can include one or more autonomous mobile work systems capable of sensing the state of the variable reflectance base stations via sensors such as electromagnetic or optical sensors capable of measuring distance to the reflective base stations.

摘要： One potential result of differing characteristics for certain two-terminal memory (TTM) is that memory management techniques, such as logical-to-physical (L2P), can differ as well. Previous memory management techniques do not adequately leverage the advantages associated with TTM. For example, by identifying and leveraging certain advantageous characteristics of TTM, L2P tables can be designed to be smaller and more efficient. Moreover, other memory management operations such as wear-leveling, recovery from power loss, and so forth, can be more efficient.

摘要： The present invention is directed to a mobile sink assembly including a container partitioned into two compartments with an overflow aperture in a dividing wall providing fluid communication between an upper compartment and a lower compartment. There is a first trap in the top opening of the upper compartment and a second trap positionable below the first trap. There is a riser and valve assembly coupled to the draining aperture in the first trap and configured to control a flow of liquid from the first trap. There is a pump that pumps fluid from the lower compartment to the first trap. In this way water recirculates through the traps while particulate matter is retained in the first and second traps.

摘要： The present invention is directed to a dynamic seal tube for use in pressurized fluid-driven down hole hammer drills. The dynamic seal tube is a tube that slides within the bore of the piston and the anvil portion of the drill bit and co-operatively acts to release different volumes of pressurized fluid from the lower chamber when the piston is in different predetermined positions.
