Abstract: A Unified Access Platform capable of providing telephone and high speed data services in a number of different local loop configurations. In a first, embodiment, a broadband digital terminal (BDT) receives high speed data and telephony signals, and combines them into a cell based signal which is transported to an access multiplexor. At the access multiplexor, a first linecard generates an analog telephone signal, and a second linecard generate; a high-speed data signal. Analog telephone service is provided over a first twisted wire pair drop cable, while the high speed data service is provided over a second twisted wire pair drop cable. In an alternate embodiment, the BDT's cell based signal is transported to two separate terminals.  Analog telephone service is provided to a subscriber location from the first terminal, while high speed data service is provided to a second subscriber location from the second terminal. Yet another embodiment provides analog telephone and high speed data services from a single linecard located in an access multiplexor. The analog telephone and high speed data signals are generated on the linecard and combined using a diplexor. At the residence, a receiving diplexor is used to separate the combine signal. Still another embodiment generates a high speed data signal at an access multiplexor which contains a digital representation of the analog telephones signal. The high speed data signal is sent to the residence, where a receiving device generates an analog telephony signal and transmits the high speed data signal to appropriate terminal equipment.

Title: Child-resistant squeeze-and-turn closure, package and method of manufacturing
Inventor: ROBINSON PHILIP J
IPC: B65D50/04
Filed: 2000-09-29
Granted: 2005-12-27
Abstract: A child-resistant closure that includes a base wall, a peripheral outer wall extending from the base wall, and an inner wall spaced radially inwardly from the outer wall and having an internal thread for securement to a container finish. The outer wall of the closure has diametrically opposed circumferential gaps, and the inner wall extends axially in radial alignment with the gaps in the outer wall for circumferential abutment with lugs on a shoulder of a container. The inner wall is flexible inwardly for clearing the container lugs and permitting removal of the closure from the container finish. The outer wall thus protects the force application area of the inner wall by reason of the fact that such force application area is recessed inwardly with respect to the circumference of the outer wall. The closure resists application of planer force to the removal area of the inner wall, such as by a child biting the closure.  Furthermore, the modified dual-wall construction of the present invention may be constructed in small sizes suitable for use in conjunction with containers having small finish diameters.

Abstract: A power burner type gas-fired water heater has a fuel supply manifold which is mounted within a sealed plenum box and supplied with gas from a valve externally mounted on the plenum box and coupled to the manifold via a flex hose disposed within the plenum box and removably connected to the gas valve. By simply removing an access wall portion of the plenum box, uncoupling the flex hose from the gas valve and disconnecting the manifold from associated support structure within the plenum box, the manifold may be removed from the plenum box for replacement of the fuel supply orifices carried by the manifold. This facilitates the field modification of the water heater's input rate and/or fuel type.

Abstract: An air compressor capable of being mounted across a lifting jack is disclosed. The air compresssor outer housing has a lower section that has a inverted "u" shape cavity to be mounted across the two vertical side plates of the lifting jack to be combined into a single unit. Therefore the air compressor can be stored, transported or operated.      Within the outer housing of the air compressor, on each side face there is a cavity with a cover for opening and closing. These cavities create storage for the power-cord and hose/connector when not in use.      The top surface inside the inverted "u" section is formed with a sloping angle approximately matching the sloping top edge of the two vertical plates. This allows the air compressor to be clamped in an approximate horizontal inclination for easier operation.

Abstract: An optical device for providing threshold and comparison functions. The device comprises first and second SOA's having respective first and second propagation paths along which the first and second optical signals, input as signals P in1(.lambda.1) and P in2(.lambda.2), travel in first and second forward directions. A feedback path is provided using couplers to interconnect the outputs of the SOA's. As a result, a portion of the optical signals output from each SOA is supplied backwards into the output of the other SOA as feedback optical control signals P  feedback,(.lambda.1) and P feedback(.lambda.2). The feedback optical control signals modulate the gain of the forwards travelling optical signals by cross gain modulation (XGM). In contrast to prior art devices, the optical control signal is supplied backwards into the SOA's in a counter-propagating configuration. This allows much shorter feedback path lengths to be achieved in comparison to what is possible with prior art co-propagating configurations. Consequently, much higher bit rates can be achieved. The device may also be implemented in planar waveguide technology.

Granted: 2006-10-17
Abstract: A calibration method and apparatus for calibrating and linearizing an amplifier (102 1-n) in which an input signal (V in) is decomposed into N channels (x1(n)). Then the amplifier is modeled to generate an estimated transfer function for each channel. Using the estimated transfer function for each channel, equalizer values are computed for equalizers that are applied to each channel prior to amplification, thus enabling the amplification of amplitude and/or phase modulated signals via the non-linear amplifiers.

Abstract: The invention relates to a novel book cover which is used together with the known firm bindings, that is U-shaped steel bars. According to the invention , a flexible support material (6) is arranged in two layers (7) and (8) in parallel to the flanks (2) of a U-shaped bar (1). The layers of the book cov er that are in parallel to the flanks (2) are intimately glued together except for a flexible connection of two layers, that is either the support material (6) is flexibly arranged in relation to its two layers (7, 8) or - as shown in figure 1 - the inner surface (3) of the flank (2) is flexibly arranged in relation to the layer (7). The resin layer (19) usually fixes the leaves (19 ), said resin layer being applied on the transversal insert (9) of the support material (6). Said transversal insert (9) rests against the base (5) of the U- shaped bar (1), that is it is not firmly linked with it, when the book is closed. When the book is opened, the bound leaves (19) are vertically moved, thereby allowing the leaves to be turned so that they lie flat.

Abstract: An automated image recording and document generation system is disclosed tha t generates identity documents using image and text information that is input to the system using computer controlled video cameras. The image and text information is combined with other stored images, such as logs, signatures a nd seals, to produce official identity documents such as identity cards, driver s licenses and passports. Prior to use the system automatically enters a setup and calibration phase wherein a video camera images a backdrop having border s on the left and right vertical edges and the digitized video output is analyzed to adjust the camera zoom and to locate the center of the backdrop in front of which an individual will sit or stand to have their picture taken. The image of a person whose picture is taken is analyzed and is centered horizontally in a picture by adding or subtracting columns of background col or to the left or right side of the picture as needed. The system also adjusts the iris of the camera for brightness. After setup an individual whose pictu re is to be taken is positioned in front of the backdrop and their pictures is taken. The picture is analyzed to locate the edges of the face of the individual. The camera is tilted under control of the computer to roughly position the individuals face vertically in the picture. Thereafter, the system adds or subtracts scan lines of tire backdrop color above the face of the individual to finally position the face in the picture. The picture is also electronically adjusted for gamma and picture brightness.
