A system and method for providing a fault-tolerant remote controlled computing device. A multi-tasking operating system and at least one primary process are executed on the computing device. A first monitor process determines whether any primary process is in a fault state. In response to any primary process being in a fault state, the first monitor process resolves the fault state of each such primary process. In certain embodiments, a local copy of a common configuration file and multimedia content are stored on the computing device. The computing device polls a server at pre-determined time intervals via a public Internet connection for updates to one or more processes, the local copy of the common configuration file, and the multimedia content. In response to updates being available from the server, the computing device downloads one or more updates via a fault-tolerant network connection and plays the multimedia content based on instructions contained within the local copy of the central configuration file. In one configuration, a user-defined notification system is provided which allows users to define threshold values. Once the threshold values are satisfied, one or more users may be notified.

This is a computer-implemented method for managing and enhancing data independence among multiple logical representations and storage structures of data by accessing and updating physical storage through a relational representation. The present invention supports both data independence and storage flexibility by using membership abstraction as the equalizing access for any logical representation and actual storage, while the prior art is restricted to user-supplied denotations and catalog entries.

A disinfecting device for objects such as shoes or human body parts such as feet. The device employs light radiating from a cavity below a transparent platform, to contact and disinfect surfaces on objects placed on a top surface of the platform. The spectral range of the light is adapted to disinfect the surface with Ultra Violet light being a preferred spectral range. An upper housing may be provided above the platform to protect the user's eyes from UV radiation which is substantially indiscernible to the human eye and as a housing for a reflective means to reflect disinfecting light communicating through the transparent platform, back toward the top surfaces of the object on the platform. A signal component for user safety such as a visible light emitter, an audible alarm, or vibration of the platform may be employed to provide the user a means to ascertain emanating UV light during operation of the device.

A micro-fluid ejection head has fluid ejection elements formed as thin film layers on a substrate. Fluid flow features on the substrate channel fluid from a fluid source to ejection chambers surrounding the ejection elements. A pump on the substrate circulates the fluid from the source to the ejection chambers and back again to the source. The flow refreshes the fluid in the chambers to minimize deleterious effects of evaporation. A controller coordinates the flow rate of the pump and other variables to optimize system productivity. Other embodiments contemplate pump locations, pump types, pump enumeration, and fluidic features, such as pathways, diffusers, chokes and dimensions, to name a few.

A Bi-directional rack assembly that rotates one column of threaded cores and unscrews threaded closures while moving in the forward direction. The Bi-directional rack then mechanically changes position to engage an adjacent column of rotating threaded cores and at the end of a second molding cycle rotates the threaded cores and unscrew threaded closures while moving in the reverse (reset) direction. A set of timed-advance devices are engaged by a smaller pinion gear and idler gear assemblies to the Bi-directional rack and as the Timed-Advance devices are activated, they allow pneumatic pistons to advance the stripper plate in time with the threaded closures as they are being unscrewed from the threaded cores. A second “rapid advance” pneumatic piston eliminates the need for an external rapid rise camming feature.
