Patent EP-0465071-A2 (EP)
Inventor: EDLRIDGE JEROME M
IPC: B41J2/05
Filed: 1991-06-24
Abstract: A thermal drop-on-demand ink jet print head (10) has an array of heating elements (36) and near each heating element (36) is a compression chamber (25). Each compression chamber (25) is filled with ink from an ink reservoir (15) through an ink supply line (27) near a heating element (36). Each compression chamber (25) further has an orifice (32) for ejecting ink drops (48). A dynamic valving effect is generated by configuring a protrusion (44) around the edge of the compression chamber (25) which slightly reduces the flow area of the channel inlet. As a heating element (36) is energized, a vapor bubble (46) of ink nucleates and grows rapidly on the heating element surface. The growth of the bubble increases the pressure in the compression chamber (25), pushing the ink through the orifice (32) to eject an ink drop (48). Meanwhile, the formation of the growing bubble produces a dynamic valving action between the protrusion (44) and the heating element surface, preventing a pressure leak through the ink supply line (27). This dynamic valving effect accelerates the bubble formation in the middle of the compression chamber (25), thereby creating large-size drops which eject with high speed. As the heating element (36) is deenergized, the bubble collapses and a fast lateral pullback motion near the channel inlet enhances the replenishing of the compression chamber (25) with ink, thereby improving the frequency response of the print head (10).

Abstract: The present invention provides apparatus and methods to achieve a high speed bi-CMOS differential amplifier with controlled output voltage swing for use in amplifying low level complementary logic signals. The differential amplifier is comprised of a load current controller and a sense amplifier. The load current controller compares a desired reference voltage to the voltage drop across a simulated load. The load current controller then produces therefrom a bias voltage corresponding to the current which results in a voltage drop equal to the reference voltage. The bias voltage, when applied to the sense amplifier, limits the output of the sense amplifier to a controlled voltage swing of magnitude equal to the reference voltage.

Abstract: The switching element allows building up of ATM exchanges capable of processing cell flows at bit rates higher than 700 Mbit/s. It uses an architecture with output queues, implemented through a unique shared memory, suitably controlled in order to obtain spatial cell switching towards the outputs. ATM cells are converted into a highly parallel format by a structure named rotation memory, where through the cells are then transferred into the master memory. The rotation memory is used also for the inverse operations of format restoration towards the output. The element control circuit is entrusted with the generation of writing and reading addresses of the master memory, in order to carry out the switching proper.

Abstract: A sign inverting Booth encoder (51 and 52) included in an encoding circuit (700) generates a control signal designating a partial product having a sign different from that designated by an output signal generated from a conventional Booth encoder (1 and 3). A partial product generating circuit (702) generates a partial product according to the control signal from the encoding circuit. A partial product having a sign inverted or non-inverted is generated from a shifter/inverter circuit (10 and 12). A converting circuit (57) generates three-value redundant binary numbers using a sign inverted partial product and a sign non-inverted partial product as a set. An intermediate sum generating circuit (59) performs a redundant binary addition of the three-value redundant binary numbers to generate a final redundant binary number. A final adding circuit (61) converts the finally generated three-value redundant binary number into an ordinary binary number to generate a product Z of binary numbers X and Y. As a result, a multiplier performing multiplication at a high speed with a smaller number of elements is implemented.

Abstract: A process of decorating fabric includes the step of imparting wrinkles to the fabric oblique to the warp and weft directions and heat setting the wrinkles into the fabric. The wrinkle imparting step may include moving the fabric longitudinally and simultaneously moving portions of the fabric from side to side by frictionally engaging the fabric to an oscillating means such as an elastomeric pad or interleaved fingers and oscillating the pad or fingers from side to side. Heat setting of the fabric includes exposing the wrinkled fabric to heat at a sufficient temperature and for a sufficient duration to set the wrinkles in the fabric. Desirably, the wrinkled fabric is in contact with a transfer print paper while the fabric passes through the heat setting step to set the wrinkles and fix color on the fabric. The longitudinal movement is desirably coordinated with the side to side movement to obtain aesthetically pleasing results. The invention also includes apparatus and the product.

Abstract: Non-intrusive monitoring and analysis of real-time facsimile transmissions is accomplished. Analog impairment measurements are made on the high speed page signal in those transmissions and protocol analysis is made on the low speed control messages in those transmissions. These measurements and analysis are a powerful tool for trouble shooting service problems afflicting facsimile transmissions. Real customer traffic can be monitored to detect circuit impairments and to evaluate service being provided. A selected incoming trunk of a central office switch is accessed and a monitoring function with respect to that trunk is established. A signal classification operation (66) is performed, which identifies the presence of a facsimile transmission and what kind of facsimile transmission it is. When the classification operation has determined the presence and nature of a facsimile transmission, a series of non-intrusive impairment measurements is made (68) using the page information sent in the course of the facsimile transmission. Analog transmission impairments are identified along with signal to noise performance. Echo and delay measurements are also taken (70) and the protocols are tracked (72). The measurement data are collected (74) and analyzed (76) to ascertain whether or not the facsimile transmission was normal. A diagnostic module (76) uses the measurements to determine why any given transmission was abnormal.

Abstract: A method and apparatus for concurrent communication of analog information and digital information. In general terms, when the communication channel is viewed as a multi-dimensional space, the digital information signal is divided into symbols, and the symbols are mapped onto the signal space with a preset distance between them. The analog signal, generally limited in magnitude to less than the distance separating the symbols, is converted to component signals and added (i.e., vector addition) to the symbols. The sum signal is then transmitted to the receiver where the symbols are detected and subtracted from the received signal to yield the analog signal components. The transmitted analog signal is recreated from those components. Both half-duplex and full-duplex operation is available in accordance with this invention.
