Abstract: A switching apparatus distributes incoming calls to end point terminals that belong to a service group and that interact with the switching apparatus via messages. The messages query the end point terminals by specifying a range and asking those end point terminals that meet a criterion associated with the range to respond. By iteratively narrowing the range, for example, in a binary search fashion, one of the end point terminals is selected. In one embodiment, the range relates to fixed sequence IDs of the end point terminals and the criterion relates to whether an end point terminal is idle or not. In another embodiment, the range incorporates the idle/not idle state of the end point terminals by specifying idle time durations.

Abstract: A capability for routing calls that are destined to different called numbers to a single customer line is provided by including apparatus at the customer's line that detects called number ID signals. The detecting of called number ID signals is enabled by installing one or more called numbers ID signals in a memory of a customer premises instrument, or a coupler, that is connected to the customer's line. The installing is carried out in a process that first places the customer premises instrument, or the coupler, in a program mode, and then providing the one or more called number ID signals, for storing in the customer premises instrument, or the coupler. In one embodiment, the service provider provides the one or more called number ID signals.

Abstract: Congestion problems in networks are alleviated with a method that works toward insuring the unused capacity will always exist in elements of a network that are resources which are shared by a plurality of users and which, consequently, can be overloaded. In response to each a request to establish a connection over a path in the network, pursuant to a predetermined algorithm method either services the request, declines to service the request, or services the request after dropping an established connection. In one embodiment, when unused cavity on the path is above a preselected level, all requests are services. What unused capacity falls below a preselected threshold, a probabilistic approach is taken as to service the request or not, and as whether to drop an existing call in order to service the request.

Abstract: Service is authorized through a process that employs a randomly sequenced table lookup that is based on predetermined information that was randomly assigned. In one embodiment, a calling card is issued with a table having a plurality of entries, with each entry comprising one or more digits. When wishing to make a call, the customer enters his/her ID. That ID is communicated to the service provider, based on that ID the provider retrieves from a database a table of the information that the customer has, and proceeds to request that the customer enter information pursuant to a random selection by the service provider.

Abstract: Traffic over a secure link or tunnel is filtered to block packets that do not conform to specified requirements for the tunnel. In one embodiment, a private network, such as an ISP network, includes a filter for blocking packets not associated with an IPSec VPN tunnel. The ISP network and/or one or both of the tunnel endpoints can include monitoring modules for detecting the presence of packets that should have been blocked by the filter.

Abstract: A method that alleviates congestion problems in prior art networks by insuring that selected classes of calls have a reserved capacity, thus insuring a capability to service at least the selected level of traffic. In an illustrated embodiment, a selected capacity is reserved for voice calls, in contrast to data calls. When a connection request is made and there is unoccupied capacity, a voice call is always serviced, but a data call is serviced only if the number of established data connections is less than capacity of the path required for establishing a connection for the request, minus the capacity reserved for voice call.

Abstract: A method and apparatus for reducing delay distortion of upstream transmissions in a cable television (CATV) distribution plant. Upstream transmission in a CATV distribution plant, i.e., from the customer premises toward the head-end, is made difficult by delay distortion caused by diplexing filters used in bi-directional amplifiers and other components in the CATV distribution plant. A database storing information relating to each cable modem (CM) in the CATV distribution plant is maintained, and the delay distortion for each upstream transmission is calculated using information queried from the database. Delay distortion in the upper portion of the upstream bandwidth in a CATV distribution plant is preferably minimized by assigning CMs having a transmission path that causes relatively minimal delay distortion to the upper portion of the upstream bandwidth.

Abstract: A special orientation sensor within a hand-held electronic computing device provides for movement of a screen cursor in response to changes in the spatial orientation of computing device. The sensor provides at least two output signals that are sensitive to gravitational force in at least two different directions, and those signals assist in determining the spatial orientation of the computing device and in determining the position of cursor 120. In one illustrative embodiment the force-sensing mechanism comprises a pair of accelerometers that provide a signal corresponding to the gravitational force applied to the accelerometers. A processor responsive to the signals of the accelerometer converts those signals to cursor position signals.

Abstract: A system and method for providing telephony and high speed data access over a broadband access network, comprising a network interface unit (NIU) coupled to a backup local exchange carrier (LEC) line, the broadband access network coupled to the NIU, an intermediate point-of-presence (IPOP) coupled to the broadband access network, and at least one external access network coupled to the IPOP. The system also provides for a fail-safe mode in which the NIU supports the LEC line for lifeline services.

Abstract: A single channel neuromuscular electrical stimulation (NMES) device for the prevention of deep vein thrombosis (DVT), pulmonary embolism (PE), lower extremity edema, and other associated conditions by electrical stimulation of the muscles of the foot muscles. An electrical signal generator produces a square wave pattern of variable frequency, duration, intensity, ramp time, and stimulation on-off cycle. Surface electrodes are positioned over the foot muscles and are attached to the stimulator by various means. The stimulator is programmed in a manner to stimulate the foot muscles to reduce pooling of the blood in the soleal veins of the calf This is accomplished by only stimulating the soles of the feet.

Abstract: A method and apparatus for implanting seeds in or about a target area, such as a tumor, within a patient. The implantation device includes an implantation needle having a bore extending a longitudinally therethrough from a proximal end to a distal end of the needle, the needle bore being adapted to permit at least one seed to pass therethrough. An elongated plunger extends longitudinally through the implantation device in aligned relation to the needle bore and is selectively movable in the longitudinal direction relative the needle from a retracted position spaced apart from the needle to an extended position wherein the plunger is advanced through the needle bore to eject at least one of the seeds through the bore, out of the distal end of needle and into the target area. An optical device is carried by and operatively connected to the plunger to provide visual assistance to an operator of the implantation device to guide and verify implantation of the ejected seed into the target area.

Abstract: Including a coupler that is connected to the customer's line provides a capability for routing calls that are destined to different called numbers to a single customer line. The coupler includes a module for detecting called number ID signals received at the customer line, a switch interposed between the customer's line and port to which customer premises equipment may be connected, and circuitry for detecting when the customer premises equipment goes off hook. The coupler can also be embedded within the customer premises equipment. Alerting signals are applied to the port to which the customer premises equipment may be connected based on the called number ID signals and on the off hook state of the port to which the customer premises equipment may be connected. In some embodiments, the alerting signals also depend on additional criteria. Also, the alerting signals may be provided by the customer's line, or generated within the coupler.
