Abstract: Printing devices herein comprise an internal power supply within the body of the printing devices. Also, a processor and printing components are within the body and connected to the internal power supply. A user interface is external to the body and is connected to the processor and the internal power supply. The user interface has a universal serial bus (USB) connection. A USB hub structure is within the body and is connected to the processor, the internal power supply, and the user interface. The USB hub structure includes an integrated circuit (IC), a power connector connected to the internal power supply, and a plurality of USB connectors connected to the IC. The USB connectors can extend through the body and one of the USB connectors connects the USB connection of the user interface to the processor and the internal power supply.

Abstract: Printing devices include a printer power supply, a printer processor connected to the printer power supply, printing components connected to the printer power supply and the printer processor, and a tablet interface device connected to the printer processor and the printer power supply. The tablet interface device includes a tablet processor, a USB connection electrically connected to the tablet processor and the printer power supply, and a touchscreen surface electrically connected to the tablet processor. The tablet processor is adapted to operate independently of the printer processor.

Abstract: A method and system are provided for implementing enhanced resource utilization in Power Virtualization Center (Power VC) after a dynamic resource optimization (DRO) threshold is exceeded on all processors. A new DRO threshold by the system processor with a least utilization is defined. Utilizing the resources from the least utilized system processor to a highly utilized processor is enabled by the new DRO threshold.

Abstract: A hall monitor system includes a telephone system, a video surveillance system, and an access control system that work together to provide a fully-integrated system that can respond to a number of different emergency events. Interfaces between these systems are defined, emergency events are defined, and each of these systems is programmed with customized functions that support the defined emergency events. The customized functions that support the defined emergency events can include initiating one or more of the emergency events from any of the telephone system, video surveillance system, and access control system, making mass notification of an emergency event by the telephone system, displaying at least one image from at least one camera corresponding to an initiated emergency event from the video surveillance system, and locking or unlocking some or all of the doors by the access control system depending on the emergency event.

Abstract: The underfeed stoker has a retort (6) which is located at a height `h`, an arch having a minimum width `w`. The ratio of the minimum width `w` to the height `h` is greater than 1.5 and less than 2.

Abstract: Combustion and heating equipment includes a body with an underfeed stoker located in the lower part thereof. A jacket surrounds the body to define a heating space, different parts of which are interconnected by triangular ducts disposed in the gas pass. A screwfeeder is provided for the retort of the stoker and extends right through the body terminating in an inlet 36. A mobile hopper has an outlet for registry with the inlet and is refillable and interchangeable.
