摘要： A package for hermetically sealing a micro-electromechanical systems (MEMS) device in a hybrid circuit comprise a firewall formed on a substrate for the MEMS device and which has a height defining a cavity of the package in which the MEMS device will be sealed. A second substrate spaced from the first substrate hermetically seals the cavity when the second substrate is flip-chip bonded to the first substrate and soldered to the first substrate with a thin film metal material placed on at least a top portion of the firewall. The resulting firewall MEMS device package can be further packaged using conventional CMOS packaging techniques. By hermetically sealing the cavity, the enclosed MEMS device is protected from deleterious conditions found in the environment of conventional CMOS packaging techniques which is often detrimental to MEMS device function.

摘要： An actuation device employing square-loop latchable magnetic material having a magnetization direction (polarization) capable of being changed in response to exposure to an external magnetic field is disclosed. The magnetic field is created by a conductor assembly with non-solenoid configuration. Once the magnetization direction of the material is so changed, the external magnetic field is no longer required to maintain the new magnetization direction. The latchable magnetic material is disposed on the mobile electrode of a switching device, and another magnetic material is disposed in spaced relation to the latchable magnetic material on a stationary electrode or surface. By applying an electrical current to a conductor assembly arranged proximate the latchable material, a magnetic field is created about the latchable magnetic material, to change the magnetization direction and thereby enable the attraction or repulsion of another magnetic material located on the stationary electrode. The resulting relative displacement of the mobile and stationary electrodes effects the selective connection or disconnection of electrical contacts carried on or associated with the respective electrodes of the actuation device without requiring additional power in order to maintain the switched state of the electrodes.

摘要： A beam-steering system having high positional resolution and fast switching speed is disclosed. Embodiments of the beam-steering system comprise a diffraction limited optical system that includes a reflective imager and two controllably rotatable MEMS elements. The optical system is characterized by a folded optical path, wherein light propagating on the path is incident on each MEMS element more than once. Each MEMS element imparts an optical effect, such as angular change, on the output beam. By virtue of the fact that the optical system is multi-bounce optical system, the optical effect at each MEMS element is multiplied by the number of times the light hits that MEMS element.

摘要： A quantum-dot photon turnstile device is capable of producing a stream of regulated and directed single pairs of photons with opposite circular polarizations. This device operates by injecting pairs of electrons and holes, alternately, into a single quantum dot, where they combine to form photons. The device will efficiently and reliably produce a directed beam of such photons at regular time intervals. It will be able to operate at high frequency and at high temperature. Such a stream of regulated photon pairs will be useful in quantum cryptography, quantum computing, low-power optical communications, as a light standard, and in many other areas of technology and fundamental science.

摘要： Cellular signals or other wireless signals/messages are introduced into a building or to an outside location by transmitting packets corresponding to those signals over a data network and low cost cables to designated locations within the data network. Once the designated packets containing the signals reach the destination, they are then broadcast over the air to a terminal capable of receiving the wireless message. In a first embodiment, an in-building gigabit Ethernet network, such as that currently existing presently in many buildings, is used to distribute radio signals indoors. Instead of transmitting the radio signals over the air from a repeater connected to a base station, coded baseband signals generated by the coding processor (e.g., a CDMA Modem Unit) in the base station are packetized and sent over the Ethernet network to radio processing equipment and antennas distributed throughout the building. The radio processing equipment strips the packet headers from the baseband signal packets so those signals can be broadcast via the antennas to one or more mobile terminals. Additionally, hard handoff is employable upon entering a building using specifically configured pilot signals.

摘要： The present invention provides a micro-electro-mechanical system (MEMS) optical device. The micro-electro-mechanical system (MEMS) optical device includes a mirror having a substrate with an implanted light reflective optical layer thereover, and a mounting substrate on which the mirror is movably mounted. The inclusion of the dopant within the light reflective optical layer increases the tensile stress of the device and tends to correct the concave curvature of the mirror structure toward a desirably flat configuration.
