Publication number: 20240308516Abstract: A driving assistance device includes a processor connected to a memory. The processor detects a latent recognition region that is unconsciously recognized by a human in an entire imaging region of a captured image. The captured image is captured by an external camera that is provided in a mobile body. The captured image is an image of at least a traveling direction in which the mobile body travels. The latent recognition region is detected based on a predetermined feature value included in the captured image. The processor presents predetermined driving assistance information in a region on a display device. The region is estimated in accordance with the detected latent recognition region.Type: ApplicationFiled: May 23, 2024Publication date: September 19, 2024Applicant: Panasonic Automotive Systems Co., Ltd.Inventors: Takaaki SEKI, Koichi EMURA, Masataka KATO

Patent number: 7372741Abstract: A nonvolatile memory apparatus which includes plural memories one of which is a nonvolatile memory such as a Flash EEPROM capable of being specified a plurality of operations from a processing unit of the apparatus including an erase operation, the erase operation in the nonvolatile memory performs a threshold voltage moving operation and a verify operation, and the nonvolatile memory is capable of releasing the I/O bus during the erase operation to thereby allow accessing of other memories and/or system components. For example, during this erase operation, the Flash EEPROM is able to free the I/O data terminal such that the EEPROM becomes electrically isolated from the CPU. The CPU is then able to perform data processing by the system bus where information can then be transferred/received such as between other memories, e.g., ROM and RAM, and otherwise with the I/O port.Type: GrantFiled: June 29, 2006Date of Patent: May 13, 2008Assignees: Renesas Technology Corp., Hitachi ULSI Systems Co., Ltd.Inventors: Koichi Seki, Takeshi Wada, Tadashi Muto, Kazuyoshi Shoji, Yasurou Kubota, Hitoshi Kume

Patent number: 7309892Abstract: A field-effect semiconductor element implemented with a fewer number of elements and a reduced area and capable of storing data by itself without need for cooling at a cryogenic temperature, and a memory device employing the same. Gate-channel capacitance is set so small that whether or not a trap captures one electron or hole can definitely and distinctively be detected in terms of changes of a current of the semiconductor FET element. By detecting a change in a threshold voltage of the semiconductor element brought about by trapping of electron or hole in the trap, data storage can be realized at a room temperature.Type: GrantFiled: May 24, 2006Date of Patent: December 18, 2007Assignee: Hitachi, Ltd.Inventors: Kazuo Yano, Tomoyuki Ishii, Takashi Hashimoto, Koichi Seki, Masakazu Aoki, Takeshi Sakata, Yoshinobu Nakagome, Kan Takeuchi

Patent number: 7020028Abstract: An EEPROM having an erasing control circuit that performs at least the read out operation one time on the corresponding memory cells after an erasing operation is performed in connection therewith. The erasing operation is automatically performed by the internal erasing control circuit while the EEPROM is electrically isolated from the microprocessor in response to instructions from the microprocessor. The control by the microprocessor requires only a slightly short period of time during which the erasing commencement is instructed while the EEPROM remains in the system during the erasing operation. In one aspect of the disclosure, a Vcc power source is applied to a source region or a drain region of each nonvolatile semiconductor memory cell, and an erasure voltage having a polarity opposite to that of the Vcc power source is applied to a control gate electrode.Type: GrantFiled: May 4, 2004Date of Patent: March 28, 2006Assignees: Renesas Technology Corp., Hitachi ULSI Systems Co., Ltd.Inventors: Koichi Seki, Takeshi Wada, Tadashi Muto, Kazuyoshi Shoji, Yasurou Kubota, Hitoshi Kume

Publication number: 20050032276Abstract: A semiconductor quantum memory element is disclosed which can share the terminals easily among a plurality of memory elements and can pass a high current and which is strong against noises. In order to accomplish this a control electrode is formed so as to cover the entirety of thin film regions connecting low-resistance regions. As a result, the element can have a small size and can store information with high density. Thus, a highly integrated, low power consumption non-volatile memory device can be realized with reduced size. A method of forming a memory element is also disclosed including performing the following steps of forming a first insulating layer, a second insulating layer, a first conductive layer and a layer of amorphous silicon. The amorphous silicon layer is crystallized to a polycrystalline silicon film. Semiconductor drains are deposited to form charge trapping and storage regions.Type: ApplicationFiled: September 9, 2004Publication date: February 10, 2005Inventors: Tomoyuki Ishii, Kazuo Yano, Koichi Seki, Toshiyuki Mine, Takashi Kobayashi
