Patent number: 11855894Abstract: A cloud server includes an equipment information storage that stores equipment table information; an equipment controller that generates control information; an encapsulator that generates control notification information by encapsulating the control information and adding header information for specifying a control device as a sending destination; and a notification information sender that sends the control notification information to the control device based on the header information. Upon acquiring the control notification information from the server, the control device removes the header information from the control notification information and decapsulates to extract the control information, and sends the extracted control information to a controlled equipment.Type: GrantFiled: May 13, 2021Date of Patent: December 26, 2023Assignee: Mitsubishi Electric CorporationInventors: Takayoshi Tonomura, Takamitsu Yamada, Kazuaki Matoba

Patent number: 6999107Abstract: An image is scaled by a desired scaling factor by using an upper scaling factor slightly greater than the desired scaling factor and a lower scaling factor slightly less than the desired scaling factor. The upper and lower scaling factors are applied to different parts of each horizontal or vertical line in the image. Both the upper and lower scaling factors are fractions with numerators and denominators less than the numerator and denominator of the desired scaling factor. The lower scaling factor may be obtained by decomposing the desired scaling factor into unit fractions. Regardless of the value of the desired scaling factor, the image can be scaled without the need for a large interpolation coefficient memory, and without resorting to iterated scaling and its attendant large data transfers.Type: GrantFiled: July 21, 2003Date of Patent: February 14, 2006Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kazuaki Matoba, Kouhei Tamano

Patent number: 5864374Abstract: A dichroic mirror for reflecting red light for optical separating and a dichroic mirror for reflecting red light for optical synthesizing are installed on the same plane in an image generating apparatus of the present invention. In addition, a dichroic mirror for reflecting blue light for optical separating and a dichroic mirror for reflecting blue light for optical synthesizing are installed on the same plane. Accordingly, a compact configuration can be realized. Since a main reflecting mirror is a rotating elliptic mirror and a lamp is located on a focus or around the focus, a lighting equipment which irradiates conic luminous flux can be realized.Type: GrantFiled: March 29, 1996Date of Patent: January 26, 1999Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Toshio Ito, Yoshisuke Ohtsuru, Hisao Koizumi, Takio Okuda, Yasuhito Myoi, Toshimasa Tomoda, Masaaki Tanaka, Teruo Miyamoto, Toyomi Ohshige, Toshiyuki Yoneda, Fumio Suzuki, Kou Nishino, Kazuaki Matoba, Masanori Kojima, Hiroshi Kawamura, Kenji Kimura, Kenji Samejima, Naoki Kawamoto, Miki Fukada, Haruhiko Nagai, Kenji Maeno
