A system may comprise a control system that controls a state of a switch network, the control system having first and second thresholds that determine the state of the switch network based on the relative voltages at an input and an output of the switch network. A scaling network is coupled across the input and the output of the switch network and providing a gain scaling signal to a first input of the control system. An offset network is coupled to the output of the switch network and providing an offset signal to a second input of the control system, the first threshold being set independently of the second threshold based on the gain scaling signal and the offset signal.

A method of making a micro-fluid ejection head structure for a micro-fluid ejection device. The method includes applying a removable mandrel material to a semiconductor substrate wafer containing fluid ejection actuators on a device surface thereof. The mandrel material is shaped to provide fluid chamber and fluid channel locations on the substrate wafer. A micro machinable material is applied to the shaped mandrel and the device surface of the wafer to provide a nozzle plate and flow feature layer on the shaped mandrel and wafer. A plurality of nozzle holes are formed in the nozzle plate and flow feature layer. The shaped mandrel material is then removed from the device surface of the substrate wafer to provide fluid chambers and fluid channels in the nozzle plate and flow feature layer.

A method of making a micro-fluid ejection head structure and structures made by the method. The method includes planarizing a heated substrate component of a micro-fluid ejection head structure by applying a clamping voltage to an electrostatic chuck sufficient to hold the substrate component in a planarized orientation. A polymeric nozzle layer is laminated to the heated substrate component in a manner sufficient to provide a planarized nozzle layer on the substrate component.

Embodiments include apparatus, methods, and systems of an electronic module for a system board having at least one pass-thru hole. An exemplary electronic module, connectable to a system board with a pass-thru hole, includes a first portion coupled to one side of the system board. The first portion has a printed circuit board (PCB) with plural processors. A second portion of the electronic module couples to a second, opposite side of the system board. The second portion has a power system board electrically coupled to the first portion. The second portion also includes a thermal dissipation device that extends through the pass-thru hole of the system board.

Embodiments include apparatus, methods, and systems having a multi-chip module with stacked redundant power. An exemplary apparatus has a module having plural processors. A first power system is coupled, in a vertically stacked configuration, to the module for providing power to the module. A second power system provides power to the module and is coupled, in a vertically stacked configuration, to the first power system. Each power system serves as a duplicate for preventing failure of the module upon failure of one of the power systems. A thermal dissipation device is disposed between both the first and second power systems and the first power system and module such that the thermal dissipation device dissipates heat, via heat exchange, away from the processors, the first power system, and the second power system.

A dispenser for sheet materials includes a top portion, a bottom portion, and a restraining member preventing the top and bottom portion from separating. The top portion and the bottom portion can telescope to vary the dispenser's overall height. In one embodiment, by designing a dispenser having bottom sidewalls and top sidewalls of approximately the same length, problems with access to the exposed sheet or excessive manipulation to change the dispenser's height can be avoided. In another embodiment, by designing the dispenser such that the height of the dispenser can automatically reduce as the sheet material is depleted or where the height can be adjusted by simply pushing down on the dispenser's top makes the dispenser convenient to use.

A method and apparatus for quantifying and rating customer demand based on measuring desires, delivery and dollars paid. The 3-D customer demand rating method and apparatus provides a series of steps for building, collecting, indexing, rating and analyzing the demand levels customers have for a particular supplier. Customers submit their desires for a set of attributes and evaluate a supplier's ability to delivery them for a given price. Indexed scores for desires, delivery and dollars paid with common scales provide direct comparison and interpretation of which attributes suppliers deliver on best. Demand ratings for each supplier provide a way to benchmark competitors. Groups of customers that possess similar levels of desire and are willing to pay the same price are created. These demand segments are then used so suppliers can create the right mix of Attributes to offer at the right price.
