Abstract: Thin film AMA in an optical projection system and a method for manufacturing the same are disclosed. The thin film AMA has a substrate having electrical wiring and a connecting terminal, an actuator, and a reflecting member (160).  The actuator has a supporting layer (120), a bottom electrode (125), an active layer (130), and a top electrode (140).

Title: Substrat polycristallin a grain columnaire pour cellule photovoltaique et perfectionnement du procede de fabrication
Inventor: MOORE CHAD B
IPC: H01L21/20
Filed: 1998-03-02
Abstract: La présente invention se rapporte à des perfectionnements concernant des techniques de fabrication de feuilles polycristallines à grain columnaire particulièrement destinées à servir de substrat ou de plaquettes pour cellules photovoltaïques. Cette feuille est faite de silicium (200) reposant sur un support d'enfournement (100). Le support d'enfournement (100) et le silicium (200) sont soumis à un profilage thermique dont la totalité favorise la croissance columnaire. Ce profilage thermique crée, d'abord une zone fusionnelle (300) dans laquelle une couche de coiffe à film mince croît au-dessus du silicium, puis une zone de nucléation (400) dans laquelle se produit une nucléation préférentielle au niveau de l'interface entre la couche de coiffe et le silicium en fusion, et enfin une zone de croissance dans laquelle coexistent le liquide et une couche à feuille polycristalline de croissance. Une zone d'annelage (500) se crée aux endroits où la température de la couche à feuille polycristalline après croissance (600) est réduite de manière contrôlable de façon à obtenir une libération des contraintes.

Title: Method and apparatus for controlling lights and other devices
Inventor: BOGDAN ALEXEI
IPC: H05B37/02
Filed: 1999-01-19
Abstract: A dimmer for dimming gas discharge and incandescent lamps can be installed in place of a standard wall-mounted light switch and connected to existing wiring. The dimmer has a switch coupling one or more full wave bridge rectifiers to a main AC source and to existing power wires running through the wall to the fixture. The bridge rectifiers are controlled by the dimming switch such that either the normal AC source waveform is transmitted over the power wires, or a full wave positively or negatively rectified AC waveform is transmitted, or else no voltage is transmitted. At the fixture, the transmitted power waveform is applied to the lamp power terminal of the lamp or ballast as well as to a decoder. A dimming interface receives the decoder output and appropriately adjust lamp brightness by changing the operating conditions of the lamp in accordance with this output. The dimmer may also be used to control general household devices containing a front-end full wave bridge rectifier.
Patent CA-2284022-A1 (CA)
Inventor: YANG RUI LIANG
IPC: H04N17/00
Filed: 1997-04-25
Abstract: A digital television satellite or cable system broadcasts to receiver/decoders which also receive control information (control programs, i.e. applications) to allow such tasks as reviewing television programme listings, setting up home banking interactions, and answering quiz questions connected with programmes being transmitted. The invention provides a method of developing such control programs on a workstation 4013. The workstation is coupled to a receiver/decoder-type unit 2021 which substantially duplicates the receiver/decoder with a television set 2023 coupled thereto. Control programs are developed including control statements responsive to signals from the workstation and test statements which return signals to the workstation. The program is passed to the receiver/decoder-type unit, and a synthetic broadcast digital television signal is generated (at 4045) and fed to the receiver/decoder-type unit. The control program is then run on the receiver/decoder-type unit, the program responding to control signals from the workstation and returning test signals thereto.
Patent CA-2284431-A1 (CA)
Title: A communication network utilizing autonomous servers to establish a communication session
Inventor: RAMEY KENNETH SCOTT
IPC: H04M7/00
Filed: 1999-10-01
Abstract: An architectural model is proposed which enables the breaking of the dedicated bond between voice-oriented peripheral equipment (PE) based resources and the voice call processing services that classically reside in PBXs, Central Offices, and Key Systems. In addition to being able to physically remote voice PE across data networks, this model enables the voice PE to become a shareable, network-owned resource (as per a Distributed Client/Server model) rather than the dedicated, non- shareable resource of a single voice host attached to the network. This places the voice PE in the same league that data resources (eg bridges, routers,...) and server-based applications have always been. Disjoint voice products based upon this proposed architectural model would likewise be able to simultaneously share voice PE resources, thereby enabling equipment concentration and it's corresponding cost reductions at network level, as well as PE-based sparing/redundancy. In addition, a new, more powerful usage paradigm is described for the telephone that resembles that of the PC. Of course, nothing prevents the network from being configured with only a singleton voice client utilizing the various servers. This degenerate case then corresponds to a distributed, but still logically unbundled PBX complete with traditional telephones.
