Patent number: 10088366Abstract: The present disclosure provides a human body detecting device capable of increasing the sensitivity. Multiple first infrared ray reception paths are defined by any one of multiple lenses and multiple detecting units. Multiple second infrared ray reception paths are defined by one lens adjacent to the any one of multiple lenses and multiple detecting units. Lens array is configured so that one of multiple first infrared ray reception paths and one of multiple second infrared ray reception paths overlap with each other. The front-side electrodes of detecting units respectively corresponding to one first infrared ray reception path and one second infrared ray reception path of the multiple detecting units have the same polarity.Type: GrantFiled: March 11, 2016Date of Patent: October 2, 2018Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yoshihiko Harano, Yusuke Hashimoto, Tomohiro Kamitsu

Patent number: 8648307Abstract: An infrared ray detector comprises a prism element, a condenser lens, and an infrared ray receiving unit. The prism element is configured to convert the infrared ray irradiated from a detection area of a viewing field to the infrared ray proceeding toward the condenser lens. The condenser lens is configured to concentrate the infrared ray into the infrared ray receiving unit. The infrared ray receiving unit includes a plurality of the infrared ray detection elements. The infrared ray detection elements are arranged in an alternate fashion so as to output electrical signals of positive polarity and negative polarity. Consequently, the infrared ray detector is configured to detect the infrared ray irradiated from a plurality of the detection area, and is configured to detect the infrared ray on the basis of movement of the human in the detection area.Type: GrantFiled: June 5, 2008Date of Patent: February 11, 2014Assignee: Panasonic CorporationInventors: Takayuki Nishikawa, Tomohiro Kamitsu, Yoshiaki Honda

Patent number: 8591716Abstract: A semiconductor substrate with anode pattern is anodized to be shaped into an optical lens. The anodization utilizes an electrolytic solution which etches out oxidized portion as soon as it is formed as a result of the anodization, to thereby develop a porous layer in a pattern in match with the anode pattern. After being removed of the porous layer, the substrate is treated to smooth out minute projections remaining in the top surface of the substrate, thereby obtaining the lens of good transmissivity.Type: GrantFiled: August 24, 2006Date of Patent: November 26, 2013Assignee: Panasonic CorporationInventors: Yoshiaki Honda, Takayuki Nishikawa, Tomohiro Kamitsu

Patent number: 7718970Abstract: An infrared detection unit includes a base carrying an infrared sensor element, and a cap configured to be fitted on the base to surround the infrared sensor element. The cap has a top wall with a window in which a semiconductor lens is fitted to collect an infrared radiation onto the infrared sensor element. The semiconductor optical lens is formed from a semiconductor substrate to have a convex lens and a flange which surround said convex lens. An infrared barrier is formed on the semiconductor lens to block the infrared radiation from passing through the boundary between the circumference of the convex lens and the window. Accordingly, the infrared sensor element can receive only the infrared radiation originating from a detection area intended by the convex lens.Type: GrantFiled: November 24, 2006Date of Patent: May 18, 2010Assignee: Panasonic Electric Works Co., Ltd.Inventors: Yoshiaki Honda, Takayuki Nishikawa, Tomohiro Kamitsu

Patent number: 7671335Abstract: An infrared detector includes a circuit block carrying an infrared sensor element and electronic components. The circuit block is composed of a dielectric resin layer and a first substrate formed with a circuit pattern and mounting the electronic components. The dielectric resin layer is formed in its top with a recess which defines around its periphery with a shoulder for supporting opposite ends of the infrared sensor. The first substrate is integrated to the lower end of the dielectric resin layer with at least one of the electronic components being molded into the dielectric resin layer to make the circuit block of a unified mold structure.Type: GrantFiled: November 8, 2006Date of Patent: March 2, 2010Assignee: Panasonic Electric Works Co., Ltd.Inventors: Takayuki Nishikawa, Sadayuki Sumi, Tomohiro Kamitsu, Ryo Taniguchi, Masaya Hirata, Shin Sato
