Abstract: Telephony apparatus 10 enables PBX 14 to receive ANI and DNIS information and to provide this information to customer business applications. Trunk adapter 20 includes an ISDN primary or basic interface 20A that receives ANI and/or DNIS information from a network provider's switch. The trunk adapter, in response to answer supervision from the PBX, employs DTMF signals to outpulse this information, via a novel protocol, over a T1 interface, through a PBX 14 to a VRU 14A. The VRU 14A subsequently provides the ANI and/or DNIS information to a Host data processor 12. The PBX 14 is essentially "transparent" to the DTMF tones that are used to convey the ANI and DNIS information from the trunk adapter 20 to the VRU 14A.

Abstract: A waveshaping circuit for producing a bus output voltage signal having a substantially sinusoidal rising transition from a low voltage level to a high voltage level in response to the rising edge of a data input signal and a substantially sinusoidal falling transition from the high voltage level to the low voltage level in response to the falling edge of said data input signal uses AC coupling to control the waveshaping. This allows the circuit to operate with a large ground offset voltage difference between circuit ground and bus ground. An exponential current source (26) provides current to a regulator bus driver (28) which charges and discharges a capacitor (30) in response to the rising edge or falling edge on the data input signal. The current increases exponentially in response to the rising or falling edge on the data input signal and then decreases exponentially when the bus output signal reaches one-half of its intended full voltage swing or falls below one-half the full voltage swing to produce respectively the sinusoidal rising and falling voltages at the bus output. The regulator bus driver (28) regulates the voltage at the bus output (16) when the voltage reaches the intended full voltage. In practice, the regulator bus driver (28) creates it own regulated high voltage level over supply variations from 9-16 volts.

Abstract: An electronic graphic system (1) comprises a memory (2) for storing data representing an image and a user operable stylus and touch tablet combination (4) by which the user can select a notional painting implement a colour with which to paint and can create data defining positions in the image at which painting is to occur. An address generator (5) is arranged to generate address data identifying addresses in the memory (2) corresponding to the user created position data. The stylus and touch tablet (4) is pressure sensitive and generates a parameter depending on the pressure applied via the stylus by the user. The address generator (5) generates address data at intervals dependent on the instantaneous value of the pressure related parameter. In one embodiment the interval is a distance between identified addresses in the memory (2) and in another embodiment the interval is a period of time. In this way the system simulates an implement having a paint flow rate which is pressure related. The stylus may be connectable to a source of pressurised air and arranged so as to simulate the feel of an airbrush.

Abstract: A graphics editor generates an appearance construction graph (ACG) which represents an image formation process as a directed acyclic graph (DAG). The ACG includes nodes representing image fragments (sources), image transformation operations (transforms), and outputs (viewable images - sinks) which can be displayed, for example, in a window of a display screen, and manipulated to construct and edit complex images. Accordingly, the displayed ACG is a user interface that permits complex graphics images to be constructed in a straightforward manner, and thus easily understood and manipulated (edited) by an operator. The nodes in the ACG are selectively interconnected by links (edges) therebetween. The complex image represented by the ACG can be constructed and displayed in a viewer window on the display screen by "running" the ACG. The graphics editor "runs" the ACG by performing operations on image fragments as defined by the interconnected nodes of the ACG.

Abstract: A clamping ring (24), for clamping an end collar of a protective bellows to one end of a universal joint in a vehicle transmission, is made of resilient material having two overlapping end portions (30,32). One end portion (32) has a tongue (36) extending through a slot (34) defined in the other end portion (34). In its relaxed state, the material of the ring holds the tongue (36) midway of the slot (34). When the ring is placed over the end collar of the bellows, the ring expands slightly to permit this, the tongue (36) moving towards a "high" stop (40) at one end of the slot (34) . The ring then resiles slightly so as to hold itself on the bellows. When the bellows, with the ring in position, is placed over the end of the universal joint, the ring once more expands slightly to permit this. The ring is then tightened by moving the end portion (30) until a hook (42) engages a shoulder (44) on the other end portion (32), the tongue (36) moving towards a "low" stop (38) at the other end of the slot (34).
