Abstract: A control system for use in a conventional telecommunications system comprising a common telephone line to which plural telephones may be connected. The line is arranged to carry plural series of electrical ring-initiating signals, each for a respective one of plural telephone numbers serviced by the line. The control system comprises plural controllable ports and a controller. Each of the ports is associated with a respective one of the series of ring-initiating signals and is arranged to have a telephone and/or some auxiliary device, e.g., FAX machine, answering machine, computer, etc., connected thereto. The controller is coupled to the line and the controllable ports and detects an analyzes each of the plural ring-initiating signals on the line and also monitors the status of the line, e.g., if there is a "busy signal", an "on-hook signal", an "off-hook signal", or other signal on it. Depending upon line conditions the system controls the ports to which the telephones or other devices are connected, e.g.

Abstract: A vaporizing device, preferably in the form of an inhaler, for directing steam in a downstream direction to the region of a user's face. A steam generating and control section includes a cup member for receiving a liquid to be vaporized, and a heater means is provided in a recess of the cup member for heating the liquid to generate steam. The generated steam is directed through a hood section attached to the steam generating and control section for directing the steam in a downstream direction to a user's face. The steam generating and control section includes at least one air-inlet slot for permitting ambient air to enter the device, an exit slot for permitting steam to exit the device, and an adjustable valve assembly downstream of the cup, air-inlet slot and exit slot to adjust the volume and velocity of steam flowing into the hood section.

Abstract: A vaporizer and/or facial treatment device includes a casing in it for retaining a liquid to be vaporized, and a hood having collapsible shield section movable from an opened, extended condition for controlling the flow of steam exiting through an opening in the casing, to a closed, collapsed condition when the hood is not in use.

Abstract: The engine ignition circuit on a motor vehicle is controlled by an electronic switch which is part of a receiver/controller unit on the vehicle. A separate self-contained transmitter unit generates a seven digit coded address at a certain baud rate which modulates an RF carrier of a certain frequency. In the receiver/controller unit, if the baud rate and the carrier frequency of the transmitted signal are correct, the coded address is compared with a stored coded address. If they match, the electronic switch is closed, enabling the vehicle engine to be started. The usual ignition switch on the vehicle must be closed before the receiver/controller unit can be effective. The receiver/controller unit remains on for a minute or two after the ignition switch is opened.
