Patent CA-2231447-C (CA)

Abstract: A mobile telephone network stores a list of short dialing codes in association with each user's identity so as to define the short codes which each individual user is permitted to use for providing access to a data conversion device PAD/PH1, which gives access to a private network PDN1. When a short code is dialed on a mobile station MS1, calling data comprising the short code together with caller identification data derived from the mobile station MS1 are transmitted over the radio link I to the mobile switching centre MSC1. Prior to routing the call, the identity of the dialing station MS1 is authenticated. The short code in the calling data is then compared with the permitted list of short codes to determine whether the user is permitted to make the call. If the caller is permitted to make the call, the call is routed to a destination corresponding to the data conversion device PAD/PH1. Thus, only permitted users may access the data conversion device PAD/PH1. Furthermore, it is possible for a network operator to configure the data conversion device (PAD/PH1) such that an operator can offer a subscriber a fixed relationship between a code and a data conversion device. The device can then be configured with subscriber-specific information so as to make onward communications easier and more professional, for example through personalised welcome pages, simplified access to user-specific data, etc.

Title: Semiconductor memory asynchronous pipeline
Inventor: MES IAN
IPC: G11C11/401
Filed: 1998-04-01
Granted: 2013-06-11
Abstract: An asynchronously pipelined SDRAM has separate pipeline stages that are controlled by asynchronous signals. Rather than using a clock signal to synchronize data at each stage, an asynchronous signal is used to latch data at every stage. The asynchronous control signals are generated within the chip and are optimized to the different latency stages. Longer latency stages require larger delays elements, while shorter latency states require shorter delay elements. The data is synchronized to the clock at the end of the read data path before being read out of the chip. Because the data has been latched at each pipeline stage, it suffers from less skew than would be seen in a conventional wave pipeline architecture. Furthermore, since the stages are independent of the system clock, the read data path can be run at any CAS latency as long as the re-synchronizing output is built to support it.

Abstract: A home network architecture has an internal digital network interconnecting devices in the home. Entertainment services are introduced into the network through network interface units that are coupled to an external network and to the internal network. The network interface units perform the necessary interfacing between the external and internal networks and perform MPEG clock recovery from an MPEG video data stream. To prevent jitter when the MPEG data stream is transmitted over the internal network to set-top electronics, the recovered MPEG clock is locked by the network interface unit to the internal network clock and then transmitted over the internal network. The set-top electronics then recovers the MPEG clock from the locked MPEG clock transmitted over the internal network. The video data may then be generated using the recovered MPEG clock and displayed on a television, for example.

Title: A cascade nucleic acid amplification reaction
Inventor: KOCH JORN ERLAND
IPC: C12Q1/6844
Filed: 1996-12-05
Granted: 2008-02-26
Abstract: A DNA template consisting of multiple tandem repetitions of an oligonucleotide unit is produced by stepwise copying of an oligonucleotide comprising at least one and a half units of a nucleotide sequence showing dyad symmetry by means of a template--and primer-dependent DNA polymerase in the presence of the necessary nucleoside triphosphates during repeated cycles of denaturation and annealing, or by endless copying of a circular oligonucleotide comprising at least one copy of said oligonucleotide unit by means of a nucleic acid polymerase, which is capable of strand displacement and is substantially without 5'-3' exonuclease activity, in the presence of the necessary nucleoside triphosphates and, if necessary, a primer capable of binding to some portion of the oligonucleotide, or by known reactions. Thereafter, in a cascade nucleic acid amplification reaction, a great number of partial and complete DNA or RNA copies of said DNA template is produced by means of a nucleic acid polymerase, which is capable of strand displacement and is substantially without 5'-3' exonuclease activity, by contacting the template with said nucleic acid polymerase in the presence of the necessary nucleoside triphosphates and, if necessary, a primer capable of binding to the oligonucleotide unit, the polymerase thus synthesizing DNA or RNA originating from, ideally, each repeating oligonucleotide unit in the DNA template. These reactions can be used in methods for detecting a target molecule or group and in processes for the amplification of a particular DNA sequence.

Abstract: A disconnect having a switch mounted within an enclosure is presented. The enclosure comprises a base including a rear wall, and first and second sidewalls extending generally perpendicular from opposing side boundaries of the rear wall. The rear wall and first and second sidewalls define an interior compartment of the base for mounting the switch therein. The enclosure further comprises a cover sized to enclose the interior compartment. At least one pair of opposing protrusions extend inwardly from each of the first and second sidewalls. The pair of protrusions abut against opposing ends of the switch to restrain movement of the switch in a generally perpendicular direction and a laterally upward direction to the rear wall of the enclosure, when the disconnect switch is mounted in the disconnect enclosure. A retaining device, e.g., a ground terminal, abuts against the switch and is secured to the rear wall of the enclosure to restrain movement of the switch in a laterally downward direction.
