A time manager for a personal terminal can be generally characterized as a things-to-do file in which the user inputs a to-do reminder message along with a data and time that the terminal user wants to be alerted (reminded). The notion of a terminal time manager is advanced by displaying reminder messages directed to calling a named entity that is contained in the terminal telephone directory and by automatically calling the named entity when the user points to the displayed reminder. If the user inputs the actual telephone number to be called in place of the named entity, then the telephone number will be called even though the telephone number is not contained in the directory.

A touch-sensitive device comprising a photoelastic screen having light reflecting edges and a unique light emitting/receiving module placed at two of the four corners of the screen advantageously determines the location at which a force is applied to the screen. Circularly and linearly polarized light focused into the photoelastic screen by the modules reflects off the edges of the screen and is returned to the modules where it is absorbed by a circular polarizer. The polarization of light passing through a point at which the screen is touched is changed thereby allowing these rays or signals to pass through each module's absorber. The location as well as the magnitude and direction of the force imparted to the screen by the touch is then determined from the changes in the signals that pass through the absorber.

Control equipment employed in a customer-owned public telephone station prevents a user from making unauthorized telephone calls in the telephone system. Operating under the control of a computer in the station, the control equipment is responsive to momentary loop breaks occurring on tip and ring lines connecting the station to a central office, and to a loop break provided by the central office which reflects that the far end party has disconnected. The control equipment is also responsive to scheduled as well as as unscheduled receipt of dial tone. The combination of ongoing loop break and dial tone detection and analysis conveniently provides the desired protection for reliable operation of the customer-owned public telephone station in the telephone system. Restrictions incorporated in the station for obtaining the desired protection are applied with minimal inconvenience for the legitimate user.

A user-application program for computerized telephone ordering is generatedy a system designer who selects and interconnects pre-defined program modules and subroutines using a graphics terminal. The application program allows TOUCH-TONE input data and voice response. The present invention describes a Dialog Production System (DPS) for generating application programs for instructing a computer-controlled voice response system to provide computer-controlled voice services. The DPS includes interaction modules, each defining a basic end-user transaction which can be performed by the system, and methods for specifying module interconnection. Each interaction module controls the intercommunications with other modules and controls the devices which interface to the system. To design a dialog program to implement the desired voice service the system designer uses a graphic terminal to select and interconnect the modules to define the sequence of transactions needed to implement the desired voice service.

Option-equippable apparatus such as a computer that is not fully equipped with option circuit boards (14) has filler boards (15,16) connected to free board slots (13). In one embodiment, the filler boards (15) simulate the effect of circuit boards on airflow and act to evenly distribute the cooling air flow inside the computer cabinet (10) in order to provide improved cooling of the circuit boards. In another embodiment, the filler boards (16) block airflow between filler boards connected to adjacent board slots to direct more cooling airflow to any slots equipped with option circuit boards. The filler boards are made of electrically-conductive material (30) to absorb electromagnetic radiation emissions, and are covered with acoustically-absorbent material (33) to absorb sound emissions of the apparatus.

A personal computer connected to a display and touch screen panel is provided with a form entry system integrated therewith. The form entry system is adapted to display a predefined form and to automatically display a predefined tool, such as a keyboard, menu, calculator, etc., to facilitate inputting information in a respective field of the form or chart. Specifically, the user is prompted as to which field is to be filled in by highlighting the field and concurrently displaying as an overlay (window) the tool that the user will use to input the information called for by the highlighted field. In the case where a field calls for illustratively the insertion of a name, the system may be adapted to display a menu of names as the tool for filling in that field. The user selects the name that he or she desired to be inserted in the field by touching that name. The system responsive thereto inserts the name in that field, highlights the next field to be filled in and displays the tool for filling that field. The system may also be adapted to communicate with a host computer to obtain the information that is to be inserted in one or more fields. Also, the user may erase the tool that is displayed by the system and direct the system to display another tool, such as the aforementioned keyboard.

A voice-switched telephone circuit with center idle state improves bi-dirional gain control in loudspeaking telephones and thereby enhances the natural quality of interactive conversation. The voice-switched telephone includes: a transmit channel having a microphone and a three-state amplifier; a receiver channel having a three-state amplifier and a loudspeaker; and a hybrid circuit interconnecting the transmit and receive channels to a two-wire telephone line. The present invention is characterized by independent signal level detecting circuits for the transmit and receive channels. When the magnitude of the signal energy in the transmit channel exceeds a predetermined threshold, the transmit channel amplification is increased and the receive channel amplification is decreased by fixed equal amounts. When the magnitude of the signal energy in the receive channel from the two-wire telephone line exceeds a predetermined threshold, the receive channel amplification is increased and the transmit channel amplification is decreased by fixed equal amounts.

A time division communication system having peripheral devices controlled om a port circuit is arranged such that the port circuit may have assigned to it a variable number of time slots for any peripheral device associated therewith. Each port circuit has a microprocessor control device which is capable of controlling communication to or from the port circuit over the system time division bus or to and from the port circuit and the peripheral over a variable number of time slots, none of which are preassigned to the port circuit.
