Title: Soffit clip
Inventor: LAPOINTE LEO
IPC: F21S4/10
Filed: 1997-02-18
Granted: 2002-05-07
Abstract: A clip for retaining a set of decorative lights under the eave of a house having vented vinyl soffit panels. The clip is made of a slender strip of a resilient material having a major cross-section dimension which is smaller than the size of the perforations in the soffit panels. The slender strip has a backward bend in a mid-region thereof, defining a first leg member and a second leg member. The first leg member extends from the backward bend in a generally straight alignment defining a supportive axis of the clip. The second leg member has a first segment extending from the backward bend alongside the first leg member and a second segment extending from the first segment and defining an open loop having an opening contiguous with the first segment. This opening has a breath which is smaller than a size of the loop. The first leg member is insertable entirely into one of the perforations of the soffit panel and is readily oriented with the supportive axis of the clip laying over the upper surface of the soffit panel. When a cord of a set of decorative lights is hung from the loop, a bending moment caused by the weight of the cord in the loop about the backward bend increases a surface pressure of the first leg member against the upper surface of the soffit panel and enhances the retention of the clip to the soffitpanel.

Title: Optical multichannel system
Inventor: JOHANSSON BENGT
IPC: H04B10/275
Filed: 1996-04-03
Granted: 2007-06-26
Abstract: A communication network has a flexible bi-directional bus architecture (FBDNA) and is arranged as a ring structure. Each node of the network has at least one on/off node switch, i.e., a switch that permits or blocks transmission around what would otherwise be a ring. If the network has one node switch per node, one node switch is set initially off to avoid problems with circulating amplified spontaneous emission (ASE) normally associated with a ring structure. If a fiber break occurs, the node switch (or node switches) in the node (or nodes) next to the break and on the same side of the node as the break switches off, and the node switch that was off before the break switches on, permitting the network to operate largely as before.  If the network has two node switches per node, two node switches next to each other in neighboring nodes are initially set off, and if a cable break occurs, both node switches around a break switch off, and the node switches that were initially off switch on. The network provides protective switching of traffic and solves the problem of circulating ASE in a simple and economical way. The network also permits wavelength reconfiguration to reduce the number of required wavelengths.

Abstract: An electric type paper display having memory properties, rapid response times and multi-optical property display with an image of high quality is made. Each display element is wholly in contact with liquid in a cavity and the surface of each display element has a portion with a most positive charge. When an electrical field is applied from the outside, each display element is turned correspondingly to the direction of the electric field and, then electrically migrated through the liquid and attached to the inner surface of the cavity. Among multiple display surfaces of each display element an optical property is selected according to an image signal and is visible through a transparent support to an observer. Afterwards, the attached state of each display element, i.e., its display state is held by the action of an attraction force such as van der Waals force and electrostatic force acting between the circumferential surface of the display element and the inner surface of the cavity, even after the electric field is removed.

Title: Programmable metallization cell structure and method of making same
Inventor: WEST WILLIAM C
IPC: G02F1/19
Filed: 1997-05-28
Granted: 2002-02-12
Abstract: A programmable metallization cell (10) ("PMC") comprises a fast ion conductor such as a chalcogenide-metal ion and a plurality of electrodes (13 and 14) (e.g., an anode and a cathode) disposed at the surface of the fast ion conductor (12) and spaced a set distance apart from each other. Preferably, the fast ion conductor comprises a chalcogenide with Group IB or Group IIB  metals, the anode comprises silver, and the cathode comprises aluminum or other conductor. When a voltage is applied to the anode and the cathode, a non-volatile metal dendrite grows from the cathode along the surface of the fast ion conductor towards the anode. The growth rate of the dendrite is a function of the applied voltage and time. The growth of the dendrite may be stopped by removing the voltage and the dendrite may be retracted by reversing the voltage polarity at the anode and cathode. Changes in the length of the dendrite affect the resistance and capacitance of the PMC. The PMC may be incorporated into a variety of technologies such as memory devices, programmable resistor/capacitor devices, optical devices, sensors, and the like. Electrodes additional to the cathode and anode can be provided to serve as outputs or additional outputs of the devices in sensing electrical characteristics which are dependent upon the extent of the dendrite.
