Title: Method of controlling the operation of a packet switched cdma telecommunication network
Inventor: CHEN XIAO HUA
IPC: H04L12/407
Filed: 1992-04-03
Abstract: 2106570 9217964 PCTABS00016 The invention relates to a method of controlling the operation of a packet switched CDMA telecommunication network, wherein N  network users are connected to the network by respective terminals, and the terminal of each user is assigned an orthogonal receiver code. To improve the properties of the packet network, the network terminal wanting to transmit senses the channel forming the transmission path for the presence of the receiver code of the other communicating party, i.e. the receiving terminal, in signals transmitted by the other terminals, said receiving terminal being the terminal to which the sensing terminal wants to transmit data in packet format. If the receiver code is not detected in the channel, said terminal wanting to transmit initiates the transmission of packet-format data encoded by said receiver code, whereas if the receiver code is detected in the channel, said terminal wanting to transmit remains waiting so as to repeat the above-described sensing algorithm after a period of time.

Patent CA-2121161-A1 (CA)
Inventor: VENABLE DENNIS L
IPC: G06F9/46
Filed: 1994-04-13
Abstract: A control system for pipelined image processing emulates a multi-tasking environment using a single tasking application. A number of predefined image processing tasks are provided in a library. When a host application needs a processed image from an image source, the host application creates a pipeline of initialized instantiations of one or more of the tasks from the library. When the host application invokes the pipeline, the first data request for the heater of the image travels upstream in a first channel. The processed image header is returned down the first channel.      Then a data request for scanlines of image data is sent upstream in a second data channel. The data request ripples upstreamwardly to the upstream-mast instantiation of one of the tasks from the task library. The upstream-most instantiation of a task obtains a scan line from an image data source and returns it downstreamwardly to the host application in the second channel. Each instantiation of a task from the task library further operates on the image data. Once all of the scanlines have been processed, the memory allocations and data structures created during initialization are released to free up that memory.

Filed: 1994-08-08
Abstract: A card carrier for transport of a phone card, credit card, debit card, etc. is of paper or plastic card stock with a multi-colored design ion deposition printed on one face and a PIN and control number on the other. During production the card is part of a blow on label, attached to the rest of the label by repositional adhesive, and the blow on label is blown onto a first opaque paper carrier web inner surface, permanent adhesive affixing the label to that surface. The outer surface of the first carrier web is imaged just like the front of the card, simulating the card. A second opaque paper ply is affixed by permanent adhesive to the first ply overlying the second face of the card, but with a cutout aligned with the control number so that the control number may be viewed from exterior of the carrier. To open the carrier perforations are provided inside a permanent adhesive strip along one edge of the card, providing a tamperproof of feature, i.e. an indication of if the carrier has been opened, and allowing ready access to the card within the carrier. The first and second plies typically have a surface area less than twice that of the card.
