IPC: A61B5/308
Filed: 1992-01-31
Granted: 1995-12-12
Abstract: A connector device interposed between a fetal heart rate monitor and fetal and maternal electrodes.  The device includes a connector inserted in a leg plate.  The leg plate has a housing which contains a printed circuit board. The board or housing is detachably connected to a base.   The board has tracers which interconnect output terminals of the housing with input contacts of the housing and with a ground electrode of the base.  The output terminals lead to the fetal heart rate monitor.  The input contacts  are  in  electrical  contact  with  terminals  of  the connector, which in turn are electrically connected with the electrodes via a twisted wire pair.  The input contacts of the leg plate are preferably in the form of barrel contacts which have fingers whose free ends either electrically connect with the connector terminals or engage with a recess on an exterior periphery of the connector.

Abstract: A mobile wireless communications system, comprises a plurality of base stations with associated respective coverage zones, each base station being connected to a central host computer and being capable of establishing two-way communication with mobile units in its associated coverage zone and a switch having a plurality of line interfaces connected to the base station. The host computer can select one of the base stations in range of an active mobile unit to establish a call therewith, determine the line interface associated with the call, determine when a hand off from one base station to the next is to occur as the active mobile unit moves between coverage zones, send a hand off message to the switch identifying the current active line interface and the target line interface after hand off associated with the call, and initiate a hand off by sending a call originate message to the next base station instructing it to originate the call on the target line interface, The switch comprises a first memory for storing call data records containing channel assignment and line interface data for each call, a second memory for storing data received from the host computer identifying the target line interface with an imminent hand off from the active line interface associated with the call, and an arrangement for assigning a channel associated with the active line interface to the target line interface on receipt of a call origination signal on the target line interface. In this way, a hand off can take place simply by writing the new line interface data into the existing call data record.

Abstract: In a noise controller which forms a noise cancelling sound having a phase opposite to and a sound pressure equal to those of a noise infiltrating into a closed space, any deviation in its transfer characteristics from the initial equalization is easily checked and judged owing to the provision of an adaptive filter 10 which automatically varies the filter coefficient and forms a cancelling signal for forming a cancelling sound, a coefficient updating means 11 which updates the filter coefficient based on an error signal after the noise has been cancelled, a second simulated transfer characteristics compensation means 13 which forms the initial equalization by simulating transfer characteristics of a transmission path via the space in which the noise is to be cancelled and forms a reproduced reference signal, a white noise generating means 15 which generates white noise to check the initial equalization, and an initial equalization judging means 18 which judges the accuracy of the initial equalization based on a ratio (S/N) of the reproduced reference signal obtained from white noise to the error signal.  A change in the conditions for cancelling noise is detected in the closed space, and any deviation from the initial equalization is judged.

Title: Television projection system
Inventor: DETER CHRISTHARD
IPC: H04N9/67
Filed: 1994-02-15
Granted: 1998-08-04
Abstract: A television projection system for generating picture points of a television picture has at least three light sources which may be controlled in intensity for light signals (RL', GL', BL') of different wavelengths, wherein the hue of each picture point is fixed by means of color value signals (R, G, B) in a first base system which may be represented in a CIE diagram by corner points of a hue region (440) which are defined via wavelengths of screen phosphors.  The wavelengths of the light signals determine a second base system which shares a common range of hues with the first base system.  Further, an input circuit is provided for generating at least three electrical signals which are proportional to the color value signals (R, G, B) or contain a mixture thereof, and a control device is provided for controlling the light sources.  The control device can be triggered by the signals of the input circuit (10) and has a circuit which can transform every hue from the first base system into the second base system via a matrix.  In addition, the shortest wavelength of the light sources is 470 nm or less and the other wavelengths of the light sources are so determined that the common range of hues contains at least those corner points of the range of hues of the first base system whose wavelength is greater than the shortest wavelength determined by screen phosphors.  The circuit is so designed that the hue of a picture point within the common range of hues is identical to the hue determined by the color value signals.

Abstract: A specified and designated, non-primary color print (imaging) is applied to a substrate (paper) by mixing at least first and second differently colored toner particles having substantially uniform physical characteristics, and introducing them in desired proportions into a fluidized bed. The toner powders are uniformly mixed together in the fluidized bed (as by using rotors in addition to applying fluidizing air to the bed), and then a substantially uniform electrostatic charge (e. g. about +6.5-+8 kV D.C., which can be applied by blades on the rotor) is applied to the bed, and then the electrostatically charged mixture of toner particles is applied to the substrate, to image uniform non-primary color symbols on the substrate. The uniform physical characteristics of the powders are size (the vast majority of particles having a size between about 5 microns and about 25 microns), a resistivity of greater than 10 12 ohm-cm, and a flowability between a predefined minimum and maximum. When utilizing the fluidized bed as according to the invention, slight changes in chemical composition of the toners may be easily accommodated without change in the resulting uniform imaging.
