摘要:
Methods and apparatus for preventing stiction in control devices are provided. In one aspect, a method for controlling dither in a control device includes coupling a signal input of the control device to an analog output module, generating an output signal, and transmitting the output signal from the analog output module to the signal input, wherein the output signal causes the control device to oscillate about an output position to facilitate preventing stiction within the control device.

A liquid storage and dispensing system comprises a bladder, a container in fluid communication with the bladder, a pump in fluid communication with the container, and a dispensing conduit in fluid communication with the pump. Liquid stored in the bladder flows from the bladder to the container, and the pump draws the liquid from the container and dispenses the liquid through the dispensing conduit. The container is sized such that it can store the other components of the liquid storage and dispensing system, including the bladder, which can be collapsed and folded into a compact configuration.

A collapsible tank comprises a flexible unitary container having an inner surface and an outer surface and a flexible partial container having an inner surface and an outer surface. The inner surface of the unitary container defines a first compartment for storing a first fluid. The partial container is mounted to the unitary container to divide the unitary container into a first portion and a second portion and to form a second compartment between the inner surface of the partial container and the outer surface of the second portion of the unitary container to store a second fluid. The second portion of the unitary container is flexible and movable relative to the first portion of the unitary container and the partial container to reciprocally change the relative volumes of the first and the second compartments.

A nail for temporarily securing articles to a concrete structure includes a double-head and an elongated shank with a lower end crimped on opposite sides to establish offset undulating profiles. The nail is driven into a hole in the concrete, with conventional nail installation tools, to establish a snug yet relatively light interference fit. The nail is removed from the concrete, with conventional clawed nail removal tools, when the need for the temporary installation is complete.

A method of updating a network client with event data involves the network client registering with a computer server a unique association between a network user and a data object maintained by the computer server. The data object identifies a plurality of pre-determined events. The computer server is configured to receive event data and to update the data object in accordance with an occurrence of one of the associated pre-determined events in the received event data. The network client receives from the computer server a network client update indicating the occurrence of the one pre-determined event in the received event data. The network client then notifies the network user of the occurrence of the indicated one pre-determined event.
摘要:
A hybrid vehicle includes an internal combustion engine coupled to a combined starter/motor/generator which is, in turn, coupled to a transmission of the vehicle. The starter/motor/generator is coupled to a high voltage battery pack via an inverter and to a deployable power output panel for serving loads external to the vehicle. Whenever external loads are to be powered, a control unit automatically places the vehicle in PARK, or alternatively activates an electrical parking brake system to hold the vehicle stationary.
