  • Patent number: 5550912
    Abstract: An arrangement for routing toll calls to a predominant local exchange carrier (LEC) or to a competitive access provider (CAP). An egress switch of an interexchange (toll) carrier translates the called directory number office code to determine whether that code serves a CAP. If so, an exception table is searched to identify the CAP. If the called number is not in the exception table, the call is routed to the predominant LEC. Calls may also be routed to a customer who is served by a CAP and the predominant LEC via either of these local carriers. The billing record identifies an originating and/or a terminating CAP for the call. Optionally or alternatively, an ingress IXC switch may access a data base to determine the CAP or predominant LEC serving a called customer. The ingress IXC switch then routes the call to an IXC egress switch serving the carrier that serves the called customer. Advantageously, this arrangement efficiently serves calls using a CAP to provide part of the connection.

  • Patent number: 5485510
    Abstract: This invention relates to methods for making a credit/debit card purchase without revealing the card number to the vendor of services or goods. The card holder is connected to a data base and provides the card number, plus holder identity verification, to the data base. The data base then verifies whether the card holder is authorized to incur the expense of the purchase, and, if so, provides an authorization indication or code to the vendor; the card number cannot be derived from the authorization information, thus helping to preserve the secrecy of the card number.

  • Patent number: 5461390
    Abstract: A locator device for monitoring the location of subjects, usable in conjunction with a database system connected to a wireless network, wherein the database system causes a polling signal to be sent periodically to each of the subject's locator devices in the area. The locator device includes a wireless transceiver to receive the polling message and, in response, query a location determination device for the current location of the device. This location is then sent back through the wireless network to the database. The database determines from a record on that particular subject where that subject is supposed to be at that time. If the subject being monitored is not within the area where he or she is supposed to be, then the database may automatically contact law enforcement officials.

  • Patent number: 5452343
    Abstract: This invention relates to a method and apparatus for accessing customer meters and for controlling customer devices over a telephone line. A connection using only a single distinctive brief burst of power ringing or tone is established over a customer line between a central office and customer station equipment to alert both the customer and the customer premises equipment (CPE) or a short burst of tone to alert the CPE. The connection is between a data accessing device such as a meter reading controller and a customer premises device such as a meter interface unit. Signals are exchanged over the connection between these two units without alerting the customer via a ringing signal and without changing the supervisory state of the customer's station equipment from on-hook. The connection can also be used for controlling devices such as air conditioning units, in order, for example, to avoid overloads in a power distribution system.
