Title: Pattern Recognition Method by Using Reference Patterns Each of Which is Defined by State Models
Inventor: ISO KEN-ICHI
IPC: G06K9/62
Filed: 1990-05-09
Abstract: In a method of recognizing an input pattern represented by a time sequence of input feature vectors (a(t)) as a recognized pattern selected from a plurality of reference patterns which represent categories of recognition objects, respectively, each of the reference patterns is defined by a sequence of state models, successively supplied with the time sequence of the input feature vectors and with a sequence of preceding state vectors (h(t, s, n)), the sequence of the state models produces a time sequence of predicted feature vectors (A(t+l, s, n)) and a sequence of new state vectors (h(t+l, s, n)).  The recognized pattern is selected from one of the reference patterns that minimizes a prediction error between the time sequence of the input feature vectors and the time sequence of the predicted feature vectors.  The prediction error is calculated by using a dynamic programming algorithm.          Training of the reference pattern is carried out by a gradient descent method such as back-propagation technique.

Title: Data transmission device, system and method
Inventor: WRZESINSKI STANLEY
IPC: G08C15/00
Filed: 1993-12-09
Abstract: Abstract of the Disclosure A data transmission device (11; 111,) for use in a system (10) comprising a plurality of such devices is described along with a corresponding method of data transmission.  A data signal (at 23) is provided for transmission and a timer apparatus (16, 18; 16, 118, 160) establishes a sequence of maximum time intervals (6 hours; 6 hours and 20 seconds) during which the data signal can be transmitted.  A transmitter (18, 24, 25; 118, 24, 25) transmits the data signal during each of these maximum time intervals.  The timer apparatus (16, 18; 16, 118,  160) generates a random number (steps 33, 54; steps 172, 195) for each one of the maximum time intervals, and the transmitter (18, 24, 25; 118, 24, 25) determines the transmission times for the data signal in accordance with the random numbers provided for each of these maximum time intervals.  Preferably, the data transmission devices are part of a data transmission system (10) which includes a data receiver (12), and the data signal is obtained from and corresponds to the output of a utility meter (13).  By utilization of random numbers to randomize the transmit times of the transmission devices, the probability that data transmissions from one transmission device will interfere with data transmissions from another device is substantially minimized.

Title: Immunometric determination of an antigen or hapten
Inventor: PRADELLES PHILIPPE
IPC: G01N33/53
Filed: 1994-01-13
Abstract: The invention relates to a process for the immunometric determination of an antigen or hapten.      According to this process, contacting takes place (fig. 1A) between the antigen or hapten (3) to be determined and the antibodies (2) fixed to a solid phase in order to immunologically bond the antigen or hapten with the antibody. This is followed (fig. 1B) by immobilizing the antigen or hapten (3) by a covalent bond (4) to the solid phase (1) whilst releasing its epitope (fig. 1C). This is followed by the contacting thereof (fig. 1D) with labelled antibodies (5) and determination takes place (fig. 1E) of the quantity of fixed labelled antibodies in order to deduce therefrom the initial hapten or antigen concentration.      As a result of this stage of immobilizing and releasing the epitope, a high sensitivity is obtained using a single antibody.

Title: Apparatus for automatic initiation of data transmission
Inventor: PETERSEN BRIAN
IPC: H04L12/56
Filed: 1993-07-27
Abstract: Early initiation of transmission of data in a network interface that includes a dedicated transmit buffer is provided in a system which includes logic for transferring frames of data composed by the host computer into the transmit buffer. The amount of data of a frame which is downloaded by the host to the transmit buffer is monitored to make a threshold determination of an amount of data of the frame resident in the transmit data buffer. The network interface controller includes logic for initiating transmission of the frame when the threshold determination indicates that a sufficient portion of the frame is resident in the transmit buffer, and prior to transfer of all of the data of the frame into the transmit buffer. The monitoring logic includes a threshold store, which is programmable by the host computer for storing a threshold value. Thus, the threshold value may be set by the host system to optimize performance in a given setting.
