Abstract: Embodiments of the invention provide a fall protection system having first and second truss members, at a first distance from each other; first and second slotted housings at a second distance from each other, each housing defining a first track therein; a first plurality of connecting members connecting the first truss member to the first housing; a second plurality of connecting members connecting the second truss member to the second housing; and a first plurality of cross members connecting the first housing to the second housing. Some fall protection systems include at least two spaced apart support members and may have a length ranging from about 10 feet to about 2,000 feet in length.

Abstract: The present invention provides a personal emergency response system having a home communicator with fully integrated capabilities to provide messages and reminders on a timed basis for the well being, safety and comfort of the subscriber as well as providing the emergency response capabilities of present systems. The invention may be embodied in a small tabletop device which can include a speakerphone and other telephone functions and which is plugged into the telephone line at the subscriber's home or other facility. The unit includes microprocessor-based circuitry including an internal clock and data storage for containing control and message information. Data storage can be via a digital storage chip such as an EPROM. The invention serves as an interactive attendant for the subscriber by which the subscriber can have an increased sense of security in the ability to summon help in the event of an emergency, and in being provided with timely reminders in the course of daily activities.

Abstract: A system and method for adjusting telephonic control signals transmitted from a central station to a remote station. The signals are automatically adjusted according to the response of the remote station. The signals are adjusted to control speakerphone operation at the remote station in such a way as to provide communication with minimum audible annoyance. The method is especially useful in a personal emergency response system in which the speakerphone is part of a subscriber station to achieve a greater voice range than a voice activated speakerphone system.

Abstract: A method and apparatus for permitting a telephonic device to select the mode of dialing, pulse or tone, which is proper for the local telephone network interface to which it is connected.

Abstract: An apparatus and method for providing a positive indication at a central monitoring station of a personal emergency response system that a responder has arrived at a subscriber's location and has taken responsibility for the subscriber's aid.

Abstract: A home communicator includes aid request circuitry capable of establishing communication with a central monitoring station in response to a first predetermined activation step performed by a subscriber and test circuitry capable of self-testing the home communicator in response to a second predetermined activation step formed by the subscriber. The home communicator further includes enable/disable circuitry capable of transmitting an identification number to a central monitoring station in response to a third predetermined activation step with the aid request circuitry and the test circuitry being unresponsive prior to the functioning of the enable/disable circuitry.

Abstract: A personal emergency response system (PERS) is disclosed which includes a method and apparatus for monitoring alarm signals to provide improved emergency response capabilities and enhanced system operability. The system includes a local response center for relaying alarm signals received from subscribers to mobile on-site field personnel via individual paging units. The system is also capable of retransmitting an alarm signal in the event that a response to the original alarm signal has not been registered within a predetermined period of time. The system is also provided with redundant communications paths to minimize the possibility of a missed alarm message from a subscriber, and self-test capabilities for detecting system faults and transmitting fault messages to the individual paging units of the system.

Abstract: An apparatus and method for use in combination with a personal emergency response system. Typical systems establish a telephone communication link between a subscriber station and a central monitoring station in order to monitor the needs of elderly and/or infirm persons confined to their residences. In the normal operation of a system, a user located at a subscriber station activates a subscriber unit which transmits an alert signal via a telephone communication link to a central monitoring station which dispatches aid to the subscriber station. The system of the present invention incorporates an ancillary radio frequency receiver or transceiver subsystem as an alternate communication link in the event that telephone service becomes disabled. The ancillary radio receiver provides the user with the ability to receive radio frequency transmissions which inform the user that telephone lines have become disabled.

Abstract: An apparatus and method to test the internal functioning and operational limitations of a personal emergency response (PER) system. In the normal mode of operation of a PER system, a coded or uncoded activating signal transmitted by a portable help button activates elements of a subscriber unit in a subscriber station remote from a central station to transmit an alarm message to the central station. A subscriber unit according to the present invention includes a momentary action button, which when activated, places the subscriber unit in a test mode. While in the test mode, the subscriber unit will not transmit alarm messages to the external central station in response to a valid activating signal. The subscriber unit will, however, activate an annunciator to inform the subscriber of proper functioning of the portable help button in combination with certain elements of the subscriber unit.

Abstract: A multi-state selection switch for a personal emergency response system which permits selective operation of the system in HOME or AWAY modes. In the HOME mode, a subscriber unit located in a remote subscriber station is activated by a subscriber using either a portable or wired-in activator to transmit an alarm message to a central station via an interconnecting communications link. In the AWAY mode, the subscriber unit is inhibited from activation as a personal emergency response system by the protable activator and may be interfaced with one or more funtional subsystems of the remote subscriber station and operative to perform one or more predetermined regulating and/or monitoring functions in combination with the corresponding interfaced subsystems. The subscriber unit in the AWAY mode may be operative to transmit status messages to the cnetral station. Also, while the system is in the AWAY mode, the portable activator can be used for command or control purposes without causing an alarm to be transmitted.
