Publication number: 20040264421Abstract: Traffic that can be processed at a cell station is increased without reducing communication quality. When a channel is allocated to every time slot constituting a communication frame and radio control section receives a link channel establishment request from a personal station through a control channel allocated to any of the time slots, a control section notifies the personal station through the traffic channel of an allocation message indicating that the time slot allocated to the control channel will be allocated to a traffic channel. The transmission of the control channel is stopped when a predetermined time (a control channel transmission/reception duration) passes after the notification of the allocation message.Type: ApplicationFiled: January 8, 2004Publication date: December 30, 2004Inventors: Hirofumi Sato, Tsukasa Sasayama, Takeshi Kawashima, Koichi Aratani, Kenji Yanagi

Patent number: 6496815Abstract: There is provided a neuron which is capable of expressing an excitative coupling and a suppressive coupling by one signal by devising signals processed in the neuron to reduce a circuit area of a neural network in constructing the neural network by a digital electronic circuit. A multiplying block calculates a numerical value following a normal distribution N(wx, 1) by using a corresponding link weight w under the supposition that delay time of each pulse of an input signal follows a normal distribution of N(x, 1). Next, an adding block adds the numerical values calculated by the respective multiplying blocks one after another and a non-linear operating block counts a number of positive values within the added value obtained by the adding block. A pulse delaying block delays output pulse following a normal distribution in which delay time is 0 in average generated by a basic pulse generating block based on the result of operation of the non-linear operating block to output as an output signal.Type: GrantFiled: May 24, 2000Date of Patent: December 17, 2002Assignees: Denso Corporation, Nagoya Industrial Science Research InstituteInventor: Takeshi Kawashima

Publication number: 20020122592Abstract: An image area extract unit includes a modeling unit for generating a pixel evaluation model used for extraction, and an extract unit for extracting a characteristic portion from an original image using the pixel evaluation model. The modeling unit sequentially generates a plurality of partial polynomials according to a modified Group Method of Data Handling using a training image taken under the same condition under which the original image is taken and a supervisory image that designates the characteristic portion of the training image. Each of the generated partial polynomials is outputted to the extract unit in the form of its coefficients only when a square error satisfies a predetermined criterion.

Patent number: 5619512Abstract: A semiconductor device capable of inspecting itself efficiently. Output data from a circuit under test is supplied to a testing data-generating circuit and a non-periodic function transformation is performed so that testing data generated by the testing data generating circuit has a pseudo-random pattern. This pseudo-random pattern is fed back to the circuit under test to continue self-testing. This test is repeated a predetermined number of times that is sufficient to finish all tests for checking the circuit under test. A mathematical function having non-periodic solutions can be realized by a simple rearrangement of various conductive lines so that is is not necessary to previously prepare patterns of testing data.Type: GrantFiled: November 8, 1994Date of Patent: April 8, 1997Assignee: Nippondenso Co., Ltd.Inventors: Takeshi Kawashima, Hiroaki Tanaka
