Abstract: A seismic system includes a wireless sensor node. The wireless sensor node includes a global positioning system (GPS) device to receive a GPS time value at an interval; a temperature sensor to measure temperature; an oscillator to measure time; and a memory to store the GPS time value, the temperature, and the oscillator time. The wireless sensor node also includes a processor to determine a rate of temperature change during the interval, and to dynamically update the interval to receive the GPS time value from the GPS device, based on the rate of temperature change.

Abstract: A projection system includes a cabinet having a surface with an aperture therein, a projector disposed within the cabinet, adapted to project light through the aperture in the surface of the cabinet, and a lens disposed in the aperture to project the light onto a screen disposed generally non-parallel to the cabinet surface having the aperture.

Abstract: A method for configuring network devices in a network includes creating a domain having a management device and a plurality of select network devices. A configuration command is issued from the management device to a central network device in the domain to configure at least one of the network devices in the domain identified by the management device. The central network device then issues a configuration command to each of the identified select network device.

Abstract: A packaged MEMS device is fabricated by providing a first substrate, forming the MEMS device on the first substrate (the MEMS device including at least one element initially held immobile by a sacrificial material), optionally removing a portion of the sacrificial material without releasing the element, providing a second substrate, forming at least one release port, bonding the second substrate to the first substrate, and removing the sacrificial material through the release port to release the element.

Abstract: A MEMS article is made by forming a MEMS device on a first substrate, providing a second substrate, depositing a layer of etchable dielectric material, forming at least one lateral post-bond release-etch port by a damascene process using a sacrificial material, and bonding the two substrates together.

Abstract: A specimen stage for charged-particle scanning microscopy comprises a non-magnetic platform for supporting a specimen, at least one probe pin assembly including a probe pin for contacting a selected portion of the specimen, the probe pin being electrically insulated from the platform and being electrically coupled to an output, and an elevator mechanism operable to move the platform for bringing the specimen into and out of electrical contact with the probe pin(s), substantially without moving the probe pin(s).

Abstract: A photonic crystal device is fabricated by a method comprising steps of providing a substrate, providing a photonic crystal on the substrate, and etching a cavity under at least the photonic crystal, the cavity having an inner wall adapted to reflect light.

Abstract: A fluid sensor for use in an environment having an ambient temperature has a field-effect transistor (FET) comprising a functionalized semiconductor nano-wire, an integral heater disposed proximate to the field-effect transistor to heat the field-effect transistor to an elevated temperature relative to the ambient temperature, and integral thermal insulation disposed to maintain the field-effect transistor at the elevated temperature.

Abstract: A magnetic memory cell having read-write conductor that is wholly clad with a high magnetic permeability soft magnetic material for a pinned-on-the-fly soft ferromagnetic reference layer is disclosed. The magnetic memory cell includes a ferromagnetic data layer, an intermediate layer formed on the ferromagnetic data layer, and a soft ferromagnetic reference layer having a non-pinned orientation of magnetization formed on the intermediate layer. The soft ferromagnetic reference layer includes a read-write conductor and a ferromagnetic cladding that completely surrounds the read-write conductor to form a cladded read-write conductor. During a read operation, a read current flowing through the read-write conductor generates a read magnetic field that does not saturate the ferromagnetic cladding. During a write operation, a write current flowing through the read-write conductor generates a write magnetic field that saturates the ferromagnetic cladding and extends to the ferromagnetic data layer.

Abstract: A unitary ink supply tube guiding system for a large format inkjet printer includes a tube guide having a bottom comprising a tube support surface, and generally upwardly, preferably vertically, extending front and rear walls and an anti-buckling wall for confining movement of the ink tubes to prevent tube buckling. The ink tubes are supported throughout a full length to convey ink from stationary reservoirs to printheads mounted on a transversely movable printhead carriage. The tubes are preferably bundled together in at least one vertically extending plane and extend through front and rear substantially parallel reaches joined by a bend. The ink tubes are bundled together along a portion of their length by a protective sheath having wear resistant outer ribs which contact the tube guide. Anti-buckling stretch resistant tension ribs are preferably located along one side of the protective carrier or sheath.

Abstract: A printhead carriage for an ink jet printer having a plurality of printhead stalls therein and a printhead holddown cover having spring biased printhead holddown plungers on the underside of the cover and equal volume fluid passageways in the cover for conducting fluid from fluid inlets on said cover exposed to atmosphere to printheads in the stalls. An arcuately moveable air pump is engageable with one of a number of arcuately positioned inlets to the passageways in the carriage cover to enable a single pump to selectively apply positive pressure to prime each of the printheads in a desired sequence.
