Abstract: A bending angle of each joint (3, 4, 5) of a multiple-jointed object (1) is represented with a function (functions (1) to (4)) independent of a length between joints of the object. Based on the function, contour data is produced for a motion of each joint, which is then displayed on a screen (17). This unnecessitates the operation which has been conventionally achieved to generate functions each time the object is changed in its size. Namely, the functions are independent of the size of the object. Since parameters (D m , A mn , ψ mn , m, n, φ m ) of the functions are altered to additionally assign characteristics to changes in the bending angles of the respective joints, the object can be actuated in an action having an emotional expression.

Abstract: Transmit and receive data are stored in buffer regions defined in first and second memories of a system residing on a network. The buffer regions are pointed to by multiple descriptor rings that are also stored in the memories. In accordance with one aspect of the invention, the two memories reside on separate busses connected to a common buss containing a processor. The processor communicates with one or the other of the memories using a handshaking protocol. In accordance with another aspect of the invention, receive data incoming to the system is scattered among multiple descriptor rings. A further aspect splits a frame among multiple descriptors depending on a characteristic code carried by the frame, e.g., in a frame control field. The size of the first descriptor, smaller than that of the others, is programmed to correspond to the size of the header of each frame. Synchronization between headers and data of a frame is maintained by a frame number stored in each descriptor. Another aspect prevents blocking of the receive path upon occurrence of a blocked receive descriptor ring. One application of the invention is in a fiber distributed data interface (FDDI).

Abstract: A technique for distributing updated distance vectors used in routers, which are connected by point-to-point links having datagram service. Distance vectors are used by routers to route messages over the most desirable paths, but must be continually modified as a result of update messages passed between routers, to reflect changes in network topology. Datagram service does not normally ensure that such update messages will reach other routers, but the technique of the invention uses unique sequence numbers on all information packets containing distance vector update messages, and achieves efficient and timely distribution of updated distance vector information with only a modest storage requirements. Unlike reliable service, which requires each message to be delivered exactly once and in the order sent, the invention allows subsequent update messages to be delivered to the same neighboring router even if previous messages have not yet been received and processed. The invention also provides for retransmission of unacknowledged distance vector information, but without the burden of having to store all transmitted packets until they are acknowledged.

Abstract: A fuel injection control device controls the calculate fuel injection quantity depending upon the load condition of the engine such that the fuel injection quantity demanded by the engine can be established. This fuel injection quantity is determined based upon engine speed, intake air temperature, engine temperature, the atmospheric pressure of the intake air, and the throttle opening. When the detected intake air temperature is high for a high load condition of the engine, an intake air temperature correction factor is set such that the intake air temperature is less influential upon the establishment of the fuel injection quantity. Moreover, during acceleration, an acceleration incremental fuel injection quantity is calculated based upon different water temperature correction factors. When an engine temperature is low, the fuel injection quantity demanded by the engine is very large. Accordingly, the fuel injection control device utilizes a second water temperature correction factor which is set to be larger than a first water temperature correction factor at low engine temperatures. Thus, the fuel injection quantity for acceleration of the engine at low engine temperatures can be established in accordance with the demand by the engine.

Abstract: A differential amplifier contains a pair of differential portions (10 and 12) that together provide representative signal amplification across the full amplifier power-supply voltage range. Each differential portion normally contains a pair of like-polarity differentially coupled FETs (Q1 and Q2, Q3 and Q4) that divide a tail current (I N , I p ) into a pair of main currents (I 1  and 1 2 , 1 3  and 1 4 ). The two FET pairs are complementary. A square-root circuit (24) controls the tail currents in such a way that the sum of their square roots is largely constant. Consequently, the amplifier transconductance is largely constant.

Abstract: In known direct conversion receivers, e.g. for paging, for getting a correct polarity a.f.c. signal, the a.f.c. signal is derived from a series arrangement of a phase shifting arrangement and a multiplication arrangement, coupled to quadrature related signals (I, Q). At an output of the series arrangement a bipolar control signal is achieved having a relatively low frequency ripple component giving rise to a relatively slow a.f.c. loop response. The direct conversion receiver (1) according to the present invention comprises a.f.c. means with an offset frequency detector (17) for determining a signal (dct) as the a.f.c. signal (ct), of which an average value is proportional to a frequency offset (δf) of a local oscillator with respect to an rf input signal, the frequency detector (17) having such series arrangement in both I- and Q-paths (4, 5), allowing for a fast a.f.c. loop response, therewith improving the a.f.c performance. Due to the unipolar control signal, a series of positive or negative pulses, depending on the sign of the frequency ofset, less demand is imposed upon signal averaging, i.e. upon the loop filter. Furthermore, the receiver (1) comprises out-of-range detection means (19, 42, 45, 47) for detecting whether a local oscillator frequency (f L ) is outside a predetermined range with respect to a carrier frequency (f C ).
