Title: Optical add/drop multiplexer/demultiplexer
Inventor: FORBES DUNCAN JOHN
IPC: H04Q11/00
Filed: 1999-05-11
Granted: 2009-07-07
Abstract: An add/drop multiplexer/demultiplexer (ADM) for switching, modulating and attenuating optical signals in a fiber optic network employing WDM. The ADM has an optical multiplexer for splitting an input WDM signal into individual optical signals, leading to respective 2x2 switches. Each switch has another input originating from a plurality of "add lines". The input signals are tapped, optoelectronically converted and fed to a controller, which reads switching, modulation and attenuation instructions. The instructions can be encoded into a low-frequency dither signal that is embedded within the input optical signals. The ADM can accordingly be instructed to reroute traffic, dynamically equalize optical channel power levels, and add or remove dither, all in real time. A bidirectional ADM can be constructed from two unidirectional ADMs. Also, a single, general multi-input multi-output switch can be used to provide an arbitrary mapping between individual input and output optical signals.

Abstract: In accordance with the present invention, products may be contained within a continuous sleeve which is unitarily formed or joined to itself to form a cylindrical sleeve in a low- or no-tension condition. Products may be inserted into the interior of the sleeve after formation or captured within the sleeve during its formation. The sleeve forms a continuous path encircling the product(s) in at least one plane through the products and package, defining an axial direction normal to the plane and a circumferential direction around the product(s) within the plane. One or more axially-extending pleats are unitarily formed from the material comprising the cylindrical wall of the sleeve, such that the circumference of the cylindrical sleeve is reduced. By reducing the circumference of the cylinder the interior volume of the sleeve, and thus the finished package, is reduced, thus subjecting the products within the package to a compressive force.

Abstract: A lottery product comprises a row of pouches formed by an upper and lower layer of heat sealable plastics material which is sealed along both edges and at spaced transverse heat sealed lines to define a series of separate pouches each containing a lottery ticket. The pouches are perforated in the transverse heat sealed lines to allow separation by tearing. The tickets are numbered consecutively in the row. The pouches are folded at each perforation line so as to form a fan folded structure with each ticket lying on top of the next adjacent ticket. A tear notch is provided at the top of each pouch between the heat seal and the top of the ticket to allow transverse tearing to remove the ticket from the pouch. The row of tickets is supplied in a dispensing machine and the strength of the perforations and the tear notch is arranged so that the row can remain intact while it is dispensed and can be easily manually separated without effecting tearing at the notch. To correct mistakes in the numbering, the pouches are separated and are rejoined by a transverse adhesive tape which has a row of perforations along the centre of the tape.

Title: Wireless communications system and method of operation for reducing fraud
Inventor: MORGAN JOSEPH LAMANCE
IPC: H04W12/12
Filed: 1998-01-30
Granted: 2002-12-31
Abstract: The wireless communications system includes a home carrier and HLR memory means, associated with the home carrier, for storing a number of Home Locator Records defining the level of service to be provided to the individual subscribers of the home carrier. The Home Locator Record is at least initially configured to prohibit call termination of the respective subscriber outside of the predetermined service area of the home carrier. However, the wireless communications system also includes reconfiguring means for at least temporarily reconfiguring the Home Locator Record of a respective subscriber in response to a request for communications service involving the subscriber who has roamed outside of the predetermined service area of the home carrier if the subscriber has prepaid for the requested services. Once reconfigured, the wireless communications system can provide the Home Locator Record of the respective subscriber to a serving carried via IS-41 (Rev. A) messaging. The reconfigured Home Locator Record serves as the roaming subscriber's Visitor Locator Record which, in turn, authorizes the requestd wireless communications service. Once the requested service has been ended, either upon completion of the call or exhaustion of the prepaid services, the reconfiguring means resets the Home Locator Record of the respective subscriber such that the Home Locator Record again prohibits call termination with the subscriber outside of the service area of the home carrier in order to further protect the wirelsss communications system from fraud.

Filed: 1998-07-22
Granted: 2004-08-24
Abstract: A display rack for displaying boxes, especially boxes containing a plurality of smaller product packages (such as mint packages), comprising a base and a stand having a plurality of openings. Swing arms with lock slots are adapted to extend from two opposing sides of the openings and engage with the product boxes being displayed.      The swing arms are moveable inward and outward within a slot in the rack and are such that the arms may be either perpendicular to the vertical axis of the rack, when the arms are adjacent to the back of the rack, or tilted downward when the swing arms are distanced from the back of the rack. Consequently, the engaged product boxes may be located in a level position at the back of the rack (a position which is especially useful for loading, transport and storage) or they may be tipped in a downward position at the front of the rack to prominently display the product. The boxes are uniquely designed to include slots which accommodate the ends of the swing arms and thus hold the boxes in place in the rack and also allow for easy replacement of the boxes in the rack. In addition, a lock tab on the swing arms is engageable with openings in the boxes to removably lock the swing arms and the boxes together.

Title: Method and apparatus for automatically controlled gain switching of monitors
Inventor: JONKER RENE T
IPC: G01R22/00
Filed: 2000-02-21
Granted: 2003-11-04
Abstract: A method and apparatus for automatically controlling gain switching of a monitor. To automatically control gain switching, an electronic circuit splits an input channel into a plurality of gain channels. The plurality of gain channels are simultaneously sampled. Thereafter, the processor accesses a present buffer of a first gain channel. The present buffer contains a predetermined amount of samples which represent the input channel. Next, the processor determines whether at least one of the samples contained in the present buffer is saturated. If at least one of the samples is saturated, the processor selects an alternate gain channel. Otherwise, if none of the samples is saturated, the processor determines whether a previous buffer of the first gain channel is saturated. If none of the samples from the previous buffer are saturated, the DSP selects the first gain channel. Otherwise, the DSP selects the alternate gain channel. Thereafter, the samples are processed from more than one of the plurality of gain channels to calculate power parameters.
