Abstract: A method and apparatus for supporting a cross in a magnetic field is provided comprising the positioning of at least one electromagnet above the cross to be levitated and connecting the electromagnet to a switchable electrical power source. The display stand preferably has a support base, a pair support members extending upwardly from the base, and an electromagnetic housing positioned between the support members and disposed over the base, spaced a distance apart from the base. A permanent magnet is disposed in an upper portion of the cross. Rotational stability magnets are positioned on distal ends of each arm of the cross, and corresponding magnets are positioned on the support members adjacent the distal ends of the cross arms, in order to provide rotational stability to the cross during levitation.

Abstract: A microfluidics device includes a plurality of interaction cells and fluid control means including i) means for providing to the interaction cells a preparation fluid, ii) means for providing to the interaction cells a sample fluid, wherein each interaction cell receives a different sample fluid, and iii) means for thermal control. A plurality of cantilevers may be disposed in each of the interaction cells, the cells or chambers formed by a cartridge bottom and top that form the device, wherein each of the plurality of cantilevers is configured to deflect in response to an interaction involving a component of the sample fluid. The cantilevers in each cell are attached to a reference plane that controls for environmental factors or non-analyte deflections.

Abstract: A bidirectional data communications distribution network is established between the system operations center (SOC) and customer terminals of a load management and electrical energy distribution system. The distribution network comprises independent processor controlled, primary communications interface units (PCI) in communication with the SOC over telephone lines or other medium. Each PCI is in turn in communication with a plurality of independent processor controlled, secondary communications interface units (SCI) over electrical utility primary distribution power lines. Signals between PCIs and SCIs on the primary distribution power lines are code division multiplexed using direct sequence spread spectrum (DSSS) signal processing. Each SCI continuously polls a number of assigned customer load terminals on the low voltage side of the electrical energy distribution system, storing and calculating meter register readings and load status.

Abstract: A method and apparatus which permits a power utility to have direct control of customers loads (CD) with a view toward facilitating enablement of a load management philosophy which includes peak shaving and load deferral. A master control station (MCS), which comprises a programmable microprocessor-based central controller, is in two-way communication with a plurality of substation injection units (SIU), one of each of which is positioned at a separate substation of the power utility. Each substation injection unit (SIU), under the control of its own microprocessor, responds to master control signals from the master control station (MCS) to inject a pulse code signal onto the power lines of the utility. The system includes a plurality of remote receiver units (RRU) which are positioned at and connected to control the on and off times of customer loads (CD).
