Abstract: ABSTRACT    An interactive medical test selector for use by a patient is about the size of a book and has a screen for displaying questions to a patient, a limited number of keys by which the patient can enter answers, and a memory device for storing the patient's answers.  The test selector is battery-powered for portability and uses a low-power liquid crystal display or the like to display instructions and medical questions to the patient.        Only four keys are seen or used by the patient for answering the questions: YES, NO, NOT SURE, and NEXT QUESTION.  Additional control keys used by the medical staff are hidden from the patient.          The device is controlled by a pre-programmed microcomputer on a chip, and a ROM-based, removeable and replaceable control program which not only collects, but also analyzes the patient's answers and makes appropriate recommendations based on those answers, and drives a remote printer or computer terminal.

Abstract: ABSTRACT OF THE DISCLOSURE           A  method  is  disclosed  for  controlling  the presentation of nested overlays on a display medium.   An overlay function resource is provided which includes its own environment specification which is independent of the space and data environment specifications.  Mixing attributes are associated with each overlay and are utilized to determine which overlay space and data are to take precedence and be visible when the overlayed spaces are combined and imaged on a display medium.   In  a preferred mode  of  the  present invention, the foreground and background of each overlay are separately controlled by the mixing attributes which define the mixing rules for the layered presentation of multiple overlays.   Additionally,  the  order  of  precedence  for displaying multiple overlays may be selectively altered or varied  to  provide  multiple  displays  and  to  permit  an individual overlay to be repetitively utilized.

Abstract: Water And Heat Management In Solid Polymer Fuel Cell Stack Abstract of the Disclosure Product water and proton transfer water are removed from the cathode side of a solid polymer fuel cell assembly by an absorbant oxygen flow field plate which contacts a wetproofed carbon paper sheet abutting the cathode side of the electrolyte polymer. Water droplets appearing on the outer surface of the paper sheet are absorbed into the flow field plate and then move laterally through the flow field plate to the edges thereof under the influence of the high pressure oxygen reactant gas in the oxygen flow field. A gas-sealing bubble barrier plate borders the oxygen flow field plate to allow passage of water, but prevent passage of oxygen, out of the oxygen flow field plate.  Slots are formed in the bubble barrier plates to collect water from the oxygen flow field plates.  In a stack of the cell assemblies, water passages communicate with the slots, and all of the plates carry water through the passages to the end of the stack where the water is ejected.

Granted: 1992-07-28
Abstract: (Translation) Device for distance measurement Abstract:            Damping of a coil (L1) can be influenced by an object (1) such that the radio-frequency voltage at the coil (L1) depends on the distance (a) of the object (1) from the coil (L1).  A constant direct current is superimposed on the radio-frequency current by the coil, whereby the d.c. voltage drop across the coil (L1) is influenced by temperature which affects the d.c. damping resistance of the coil (L1). The radio-frequency excitation (5, 6) of the coil (L1) is controlled by the d.c. voltage drop in order to compensate the influence of temperature on the radio-frequency voltage so that the radio-frequency voltage depends only on the distance (a).  The radio-frequency voltage, which is non-linearly related to the distance (a), is linearized in relation to the distance (a) in a non-linear member (15) with a semi-conductor element.  The influence of temperature on the linearization is thereby compensated by means of a second semi-conductor element.

Abstract: Abstract Vehicle Multiplex System A time division multiplex system for motor vehicles and other applications in which data signals are adapted to be sent through the system in cyclical fashion during each of a series of time periods.  The system includes a communication line, a master unit connected to the communication line which includes a pulse-generating circuit for sending a plurality of timing signals out over the line for defining a plural-ity of time slots during each time period, and a plurality of transceiver units connected to the commu-nication line.  Each of the transceiver units is operable in either a transmit mode or a receive mode and includes an address-decoding circuit for identifying a selected one of the plurality of time slots on the line during each time period, a data-signal-transmitting circuit operable when the transceiver is in a transmit mode for sending the data signal out onto the line during the selected time slot, and a data-signal-receiving circuit operable when the transceiver is in a receive mode for receiving a data signal from the line during the selected time slot.  With the system of the present invention, data can be transferred onto the line from any one transceiver and received from the line by any other transceiver or transceivers to provide a system having a great deal of flexibility. The system also includes circuitry to permit power for the transceivers to be sent over the single communica-tion line from the master unit.

Abstract: The present invention concerns a polymerization catalyst of olefins, said catalyst containing an active chromium compound on an inorganic support. The catalyst in accordance with the invention is prepared by vapourizing a precursor of chromium oxide such as chromyl chloride and allowing the chromium oxide vapour to react with the surface of, e.g., silica gel support material at 160...500 DEG C. A selective binding of the chromium oxide to the support material is achieved by keeping the vapour pressure sufficiently high and the duration of interaction with the support sufficiently long so as to maintain an excess of the chromium compound in relation to the number of available binding sites on the support material. The activity of a catalyst in accordance with the invention even with a very low content of catalytic metal is as high as the activity of a catalyst of an appreciably higher metal content that has been prepared by the methods of the conventional technology.
