Abstract: Specific text and/or graphic messages for individual subscribers or groups of subscribers are distributed on a communications network such as a cable television system. An addressable controller (24) communicates with a plurality of subscriber terminals (18) served by the network. Each subscriber terminal (18) is assigned to a primary message group and may be assigned to one or more message subgroups. Messages are input to the addressable controller (24) for subsequent transmission to a subscriber terminal for display. The messages are tagged with distribution data defining at least one primary message group or message subgroup to receive the message. The tagged text messages are transmitted over the network together with signals from network service providers (10). Global messages can be sent by leaving the distribution data field blank, or filling it with a special code such as a string of zeros. Wild card tags are also permitted. A subscriber terminal (18) for receiving the messages has a first path for processing a service signal received from the network and a second path for processing a message signal received from the network. The distribution data is retrieved from a received message and used to determine if the message is targeted to the subscriber terminal. If so, the message is processed for display. The message can be displayed alone or overlaid on a video program signal being viewed.

Title: Method and device for toning a latent image on the surface of a ferroelectric recording element
Inventor: LIMA-MARQUES LUIS
IPC: G03G21/20
Filed: 1991-08-31
Abstract: The device for toning a latent image has a cylinder (1). This cylinder (1) has as recording element (2) a layer made from ferroelectric material. Arranged near the cylinder (1) is a feed roller (4) which partly dips into the toner liquid in the tank (5). Toner can be conveyed to the toner gap (8) by the feed roller (4). It is important that when the temperature of the recording element (2) is at least 0.5 degrees above the ambient temperature, the rate of development and the quality of the developed image (15) which is then transferred onto the paper web (13) is greatly increased. Increasing the temperature of the recording element (2) is served individually or in combination by the infrared heaters (10 and 12) and the heating jacket (11). The temperature of the recording element (2) can be raised directly by the infrared heater (10). The infrared heater (12) can raise the temperature of the feed roller (4), which dips into the toner bath in the tank (5) and conveys toner to the toner gap (8). This indirectly produces warming of the recording element via the toner liquid warmed by the feed roller (4). The toner liquid in the tank (5) can be heated by the heating jacket (11). <IMAGE>

Abstract: A ferroelectric memory device includes a preamplifier that couples a bit line to a sense amplifier. The preamplifier both provides additional bit line capacitance needed to enable full switching of the ferroelectric capacitor in a selected memory cell, and data signal amplification needed to obtain a reliable data signals from the memory cells after the memory device has aged and the ferroelectric capacitors in the memory cells are generating relatively small voltage signals. More specifically, the preamplifier of the present invention is a set of capacitors which can be switched between two configurations. In the first configuration, used while strobing a selected memory cell, the capacitors are all connected in parallel to the bit line, thereby providing the bit line capacitance needed to enable full switching of the ferroelectric capacitor in the selected memory cell. In the second configuration, used after the memory cell has been strobed, the capacitors in the preamplifier are disconnected from the bit line, and connected in series so as to multiply the voltage developed on the capacitors while the memory cell was strobed. The resulting multiplied or amplified voltage signal is then processed by a sense amplifier.

Abstract: A method and apparatus for replacing reels of web-like material having a paper-end gripping arm having an attraction surface and a keep pawl. A peeling member peels off a bonded end portion of the material and the material is delivered along a transport path where it is held and the bonded end portion is cut off. The cut end portion is then removed from the transport path. The cut end portion is then removed from the transport path. Two reels are supported on reel holding portions and are alternately fed to the transport path. The end portion is bonded to the reel by boring a hole in the end portion, attaching tape to the outer surface in the area of the hole and pressing the tape inwardly so that it extends through the hole and is bonded to the outer surface of the material beneath the hole.

Abstract: A measuring head (1) measures displacement by variation in frequency of an oscillator due to movement of a core in a coil. The signal from the oscillator is used to gate a high frequency crystal clock (10) into a counter (12). The count is representative of the change in frequency of the oscillator and thus the displacement to be measured. The count is compared by a microprocessor (14) with a look-up table (16) stored in the memory during initial calibration. The operating and processing electronics connected to the sensor head (1) are mounted in a connector which can be directly coupled to connectors of other sensors to form a bus connecting multiple sensors to a host.

Abstract: A method and apparatus for automatically adjusting the sensing threshold in an automatic implantable cardioverter/defibrillator with pacing capability. Fixed sensitivity is used for a specified interval following each pacing pulse and automatic sensitivity adjustment is used when spontaneous cardiac depolarization is detected. For spontaneous cardiac depolarization, the sensing threshold is automatically adjusted to a value proportional to the amplitude of the sensed cardiac signal. The sensing threshold continuously decreases between sensed cardiac depolarizations, ensuring that a lower level cardiac signal will be detected. When a pacing pulse is delivered, the sensing threshold is set to a fixed value and held at that value for a predetermined period of time such that the sensing threshold will not be affected by the cardiac response evoked by the pacing pulse. At the end of the predetermined period of time, the sensing threshold is decreased as it would following a spontaneous cardiac depolarization.
