Abstract: A split channel bridging unit includes a router that operates under the control of a control processor to route packets of information destined for a user to a modulator which is connected to the cable distribution head-end of the cable television system which serves the requesting user. The modulator encodes the digital information transmitted from the router and encodes it in an RF channel to be carded by the television cable. The cable distribution head-end combines this channel with other conventional cable television sources to broadcast these channels to its users. The customer premises equipment of the user includes an RF demodulator and packet receiver which demodulates the RF encoded signals and utilizes the packet receiver to transmit the digital information addressed to the particular user to the user's personal computer.

Abstract: A user's personal computer is coupled to a home controller which is, in turn connected to the input cable from a cable television system and to a set top box which determines the channel to be delivered to an associated television. The service provider transmits over a conventional modem communication link the alert message to the user's personal computer. If an acknowledgment by the user is not transmitted to the service provider, a command message is transmitted by the dial-up communication link to the personal computer instructing the personal computer to activate a modulator contained in the home controller to provide an RF encoded signal representing the alert message to be displayed on the television associated with the set top box.

Abstract: In accordance with an embodiment of the present invention, a home controller receives signals from the cable television system and utilizes a cable demodulator tuned to the RF frequency of the channel which carries the data information. The cable demodulator demodulates the RF encoded signals into conventional baseband digital form which are transmitted to a packet receiver which decodes packets addressed to individual users. If a packet is addressed to the user, the packet receiver transmits the corresponding data such as by an ETHERNET transceiver to the user's personal computer. A communication controller may be utilized to provide an interface between the personal computer and the cable demodulator thereby, enabling the personal computer to select the channel to which the cable demodulator is tuned, in order to permit multiple data channels to be utilized.

Abstract: A hanger nut assembly for attachment to a concrete wall form so as to embed a hanger nut of the assembly in a wall being constructed. A headless screw attaches the nut in abutment with the wall form and is readily removable to facilitate form stripping. A pipe hanger rod is subsequently engageable with the wall installed nut after wall completion.
