Patent EP-0440514-A2 (EP)
Inventor: GIESEKE BRUCE A
IPC: H03K19/0948
Filed: 1991-01-03
Abstract: A cascode logic circuit provides a pair of differential output nodes (12,13) that are pulled up by a pair of cross-coupled P-channel output transistors (11,14). The output nodes (12,13) are connected to outputs of an N-channel combinatorial network (20) that receives a differential input and functions to connect one of the output nodes (12,13) to a positive supply (Vdd) and the other to ground (Vss), depending upon the differential input, thus providing a push-pull effect. The output nodes (12,13) may be connected to the differential output of the combinatorial network (20) by source-drain paths of separate N-channel transistors (17,18), with the gates of these transistors connected to the positive supply (Vdd) to capacitively isolate the output nodes (12,13) from the combinatorial network (20); alternatively, the gates of these transistors may be clocked. A fully static latch is provided by adding cross-coupled N-channel transistors connecting the output nodes to ground, so the low side of the output is held down instead of being allowed to float. The channel types of the transistors may be reversed in another embodiment; the pull-down transistors of the differential amplifier may be N-channel and the logic and latching transistors P-channel.

Abstract: In each of a plurality of subscriber systems included in a B-ISDN for controlling access competition among a plurality of terminals under the DQDB protocol, the terminals (13) are electrically connected to a dual bus comprising a downbus (2a) and an upbus (2b) both extending from a network terminal (1). Each of the terminals has data transmission processing means (8), downbus processing means (10a), upbus processing means (10b), a timer (11) and failure detecting means (12). When data transmission request is issued from the data transmission processing means (8), the failure detecting means (12) is activated in response to this request to start the timer (12) so as to count a given time interval which has elapsed. If either a request message or data cannot be sent even when the timer takes time out, then the failure detecting means (8) determines that a failure has occurred in the dual bus.

Abstract: A protocol for authenticating a mobile customer unit to a service provider where signaling messages are encrypted and where voice communications can be encrypted. A service provider assigns to each mobile customer unit a unique "secret", along with other information such as a telephone number. At the pleasure of the service provider, a directive is sent to the mobile customer unit to create a shared secret datum based on the secret. The shared secret datum is created with the aid of a bit string that is sent for that purpose by the provider. A portion of the created shared secret datum is used for encrypting speech and the same or other portion of the created shared secret datum is used as an input to a process for creating a second encryption key. That key is employed in the mobile customer unit to encode those of the control signals generated by the mobile customer unit that affect the nature of the call in progress.

Abstract: The present invention relates to a method of traffic switching in a low-orbit satellite communication system with terminals as destination, the connecting of a terminal (13) to a land communication network being accomplished by means of a connecting station (12). The switching of the satellite (11)/terminal (13) and satellite (11)/connecting station links is possible only within a specified zone. The decision to switch the traffic is made as a function of the degradation in the quality of service and of the radio environment around a group of terminals from the said zone. The invention also relates to equipment intended for the use of this method, in particular transmit/receive terminals, as well as land interconnecting stations. Application in particular to the space sector. <IMAGE>

Abstract: The relay is preferably used as polarity reversal relay for operating direct-current motors in two directions. 
<??>It consists of two electromagnetic systems (A, B) which are combined in a common housing, their contacts (5, 6, 7) being connected in a so-called "H-bridge circuit". Each of the two electromagnetic systems has a moving contact element (5), whereas both systems together exhibit a common pair of countercontact elements, namely a normally-closed contact element (6) and a normally-open contact element (7). Both electromagnetic systems each have a coil former (1) which are preferably of identical construction and are attached to one another by means of the common countercontact elements (6, 7) so that no additional mounting elements are needed. This keeps down the number of parts; the type of mutual attachment also largely reduces the expenditure for adjustment.

Abstract: A picture signal recording device for recording color video signals includes a color signal motion detection circuit (8) that detects the quantity of motion of chroma signals from an inter-frame difference between a color difference signal from a chroma recording processing circuit (4) and a signal delayed by one frame from the color difference signal. A dynamic change smoothing filter circuit (13) smoothes sudden changes in the detected quantity of motion of the chroma signal. A luminance signal motion detection circuit (12) detects the quantity of motion of luminance signals from an inter-field difference between a luminance signal from a luminance recording processing circuit (10) and a signal delayed by one frame from the luminance signal. A maximum value detection circuit (14) detects the maximum value of the quantity of motion of the chroma signal and the quantity of motion of the luminance signal. An adaptive processing circuit (9) controls the quantity of transmission of the sub-Nyquist sampled (6) color signal depending on the maximum value. Thus, a color signal sub-sampled responsive to the motion of the picture is transmitted, while motion detection may be effected without necessitating a memory exclusively used for motion detection.

Abstract: A system for deriving signals representing a selected cross sectional area and volume of a region of interest in tissue. In the preferred embodiment, area and volume of a fluid filled cavity contained in tissue on a real time basis are determined by launching pulses of ultrasonic pressure waves along a plurality of scan lines, detecting the locations along each line that are in fluid, deriving a signal representing the incremental area within fluid that is between adjacent scan lines, deriving a signal representing the cross sectional area of a cavity within a region of interest by summing the incremental areas and deriving a signal representing the volume of the cavity within a region of interest by revolving each incremental area about an axis of the cavity so as to form an incremental volume of revolution and summing the volumes of revolution. The volume of the entire cavity is also attained by deriving the cross sectional area as just described, raising it to the 3/2 power and multiplying it by a coefficient including a function of the ratio of the long axis cross sectional area and short axis cross sectional area. Determination of the locations in fluid in the above calculations are preferably those at which a majority of an odd number of consecutive scan lines at like ranges are in fluid.
