Abstract:
A water display with multiple characteristics, providing a short burst of water or a steady stream of water of constant or variable height. The water display includes an interior cavity having a nozzle at the top for forming the desired stream size, and a flapper valve on the bottom through which the chamber may refill with water. A high pressure air line controllably provides high pressure air to the lower part of the chamber to force most of the water in the chamber out through the nozzle to provide a short blast of water to a height controlled by the air pressure. A second flapper valve, coupled to the chamber, allows a steady stream of water to enter the chamber and exit the nozzle from a water supply, typically a variable pressure water supply, so that a steady stream of water of variable and controllable height may be obtained. Use of the water display in plurality in coordination of the multiple modes of operation thereof provides a new visual effect. Various embodiments are described.
Abstract:
A method of preparing a reflection hologram which includes mounting a transmission hologram in register with a portion of transparent photosensitive holographic material there being present there between a filter to cut out zero order light transmitted through the transmission hologram, there being present on each side of an assembly which includes the hologram and the holographic material a light reflecting surface then causing a beam of light from a laser source to pass through a holographic optical element (H.O.E.) which splits the beam into two beams and causes both beams to scan in register over both the whole surface of the transmission hologram and the holographic material by directing the beams onto both reflecting surfaces so that one beam is reflected from one said reflecting surface and on passing through the transmission hologram takes-up the image information and passes through the filter to cut out the zero order light to the portion of transparent photosensitive holographic material where it interferes with the other beam which is reflected from the other reflecting surface into the holographic material then processing the holographic material to fix the holographic image therein.
Abstract:
The present invention provides a system and method for affiliating a wireless device with a wireless local area network (WLAN). An embodiment of the method of this invention comprises establishing, at a control node of the WLAN, access frequency(s) for affiliation with the WLAN. The control node periodically provides a beacon frame on the access frequency(s) that indicates the timing of affiliation with the WLAN. The wireless device determines the access frequency(s) for affiliating with the WLAN and the timing of affiliation with the WLAN based on the beacon frame. The wireless device provides self identification information via the access frequency during the beacon frame. This allows the control node to determine the access privileges of the wireless device based on the identification information. Finally, the control node affiliates the wireless device with an initial access channel from a set of access channels in accordance with the access privileges.
Abstract:
The web of the invention can comprise a super absorbent layer that can act as an moisture sensitive fuel shut-off valve, absorbent, adsorbant or reactant. The web of the invention can comprise a super absorbent fabric or layer made of a superabsorbent particle or fiber. The web can comprise a nanofiber layer having dispersed within the nanofiber layer a super absorbent particulate and optionally a second particulate material that can act as an absorbent, adsorbant or reactant. Fluid, gas or liquid, that flows through or by the assemblies of the invention can have any gas, liquid or solid material dispersed or dissolved in the fluid interact with the super absorbent particulate. If needed these materials can also react with, be absorbed by, or adsorbed onto, the active particulate within the nanofiber layer. The structures of the invention can act simply as flow-by reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters that can filter particulate from a mobile fluid in a flow-through mode while simultaneously reacting, absorbing, or adsorbing materials from the mobile fluid.
Abstract:
A new and distinct variety of Fig tree denominated ‘Sequoia’ is described. The new ‘Sequoia’ fig variety is a high quality, medium to large size, yellow-green skinned fig of the “common” type, developed for use in the fresh market fig industry. The ‘Sequoia’ tree is of medium vigor and size and is a regular and productive bearer, developing both a Breba and second crop in most years. The ‘Sequoia’ has a tight ostiole that substantially restricts the entry of most insects into the interior of the fig fruit. In comparison with the ‘Tena’ parent cultivar, the ‘Sequoia’ is substantially larger in size and has a more prolific Breba crop. The larger size of the ‘Sequoia’ allows it be harvested later into the fall when the decreased size of other cultivars such as ‘Tena’ precludes their use in the fresh market.
Abstract:
A multimedia processing system and method thereof are provided. The system and method provide for synchronizing a first clock of a multimedia decoder of a first multimedia processing device to a second clock of a multimedia encoder of a second multimedia processing device, synchronizing a first timing reference of the multimedia decoder to a second timing reference of the multimedia encoder, receiving, at a network interface of the first multimedia processing device, an encoded multimedia data stream from a network interface of the second multimedia processing device, wherein the encoded multimedia data stream is encoded by the multimedia encoder based on the second clock and the second timing reference, and decoding the encoded multimedia data stream at the multimedia decoder based on the first clock and the first timing reference.
Abstract:
A plurality of wireless clients that can operate in a shared manner using a contention based protocol are placed into a contention free mode of operation that prevents the wireless clients from initiating a data transfer. Once the wireless clients are prevented from initiating access to the wireless network, a video gateway can transmit video content in a deterministic manner to one or more of the plurality of wireless clients.
Abstract:
A negative coefficient of thermal expansion particle includes a first bilayer having a first bilayer inner layer and a first bilayer outer layer, and a second bilayer having a second bilayer inner layer and a second bilayer outer layer. The first and second bilayers are joined together along perimeters of the first and second bilayer outer layers and first and second bilayer inner layers, respectively. The first bilayer inner layer and the second bilayer inner layer are made of a first material and the first bilayer outer layer and the second bilayer outer layer are made of a second material. The first material has a greater coefficient of thermal expansion than that of the second material.

Multi-domain liquid crystal cells having twist angles less than 90 degrees, and LCDs containing such liquid crystal cells, are provided. Such liquid crystal cells are stable, particularly at zero and high fields, and provide wide viewing angles. Also provided are methods of using an adjustable particle beam in combination with a mask to generate multi-domains alignments. Such methods are useful for producing liquid crystal cells in general, and for producing the novel multi-domain low twist angle liquid crystal cells of the present invention in particular.
Abstract:
A method of preparing a copy hologram from a master hologram in which the light employed in the copying process is modified by passing an exposing beam through a light modulating array. At least some members of the array have modified light transmissivities in accordance with information derived from a reconstruction of the master hologram.
