Patent number: 6806681Abstract: An increased capacity battery holder, which allows a device to be used for a longer time duration than can be achieved from solely internally contained batteries, capable of providing additional energy to the device, beyond internal space and volume limitations of the device, having additional battery holding capacity external to the device, with the additional battery holding capacity self contained within the battery holder. The battery holder provides maximum energy output, a portion of the battery holder being matingly removably attachable and optionally removably lockable to the device. The battery holder is safe, of simple construction, easy to install and remove therefrom the device, acts as an additional means for holding and/or handling the device, and is capable of forming an integral assembly with the device. The battery holder has means for preventing inadvertent shorting and/or reversing polarity of the batteries, and optionally recharging means for recharging the batteries.Type: GrantFiled: April 30, 2002Date of Patent: October 19, 2004Assignee: Zinc Matrix Power, Inc.Inventors: Michael Cheiky, Robert B. Nimocks

Patent number: 6774946Abstract: A rechargeable battery in an electronic camera is charged without additionally providing the camera with a power generating device. When a power-supply switch of the camera is turned off, a diaphragm and a shutter are opened and a taking lens is controlled so as to set focus to infinity. Signal charge that has accumulated in a CCD is output as a charging current, and the rechargeable battery is charged by a power-supply control circuit.Type: GrantFiled: July 28, 1999Date of Patent: August 10, 2004Assignee: Fuji Photo Film Co., Ltd.Inventors: Takeshi Misawa, Akihisa Yamazaki

Patent number: 6738574Abstract: In a camera system according to the invention, a camera body and an interchangeable lens have respective identification data tables that are congruous with each other. As an appropriate data address is indicated to the interchangeable lens by the camera body, an identification data that is stored in the identification data storage section and corresponds to the indicated address is transmitted from the interchangeable lens to the camera body. The identification data judging section of the camera body compares the identification data transmitted back from the interchangeable lens and the identification data that is stored in the identification data storage section and corresponds to the address. As a result, it is determined if the dedicated accessory device is mounted on the camera body or not.Type: GrantFiled: January 28, 2003Date of Patent: May 18, 2004Assignee: Olympus Optical Co., Ltd.Inventors: Takao Nishida, Mamoru Sakashita, Masataka Ide, Makoto Harada

Patent number: 6731871Abstract: A camera includes a first power supply output circuit which outputs a first stabilized power supply voltage, a second power supply output circuit which outputs a second stabilized power supply voltage lower than the first power supply voltage, a photocoupler which has a light emitting element and a light receiving element, a detecting circuit which detects an analog signal output from the light receiving element and converts the analog signal to a digital signal, and a processing circuit which performs processing based on the digital signal. The first power supply voltage feeds into the light emitting element as an operating voltage thereof. The second power supply voltage feeds into the light receiving element and feeds into the processing circuit as an operating voltage thereof. The camera allows stable operations of the processing circuit with minuter elements and the light emitting element.Type: GrantFiled: June 4, 2002Date of Patent: May 4, 2004Assignee: Canon Kabushiki KaishaInventors: Kazunari Kitani, Masanori Ohtsuka, Takashi Kosaka

Patent number: 6628337Abstract: A camera is made compact with its internal temperature adjusted to a more appropriate temperature. A temperature T is read from a temperature sensor disposed within the camera (S100) and it is judged whether or not the temperature T exceeds a threshold Tref1 (S102). When the temperature T exceeds the threshold Tref1, the operation of the camera is changed to a power-saving mode where the power consumption is lower than in the ordinary mode (S104). The threshold Tref1 is determined to be a rated temperature at which the camera can operate stably or a temperature lower than that. Thus, the temperature in the camera can be made appropriate.Type: GrantFiled: April 18, 2001Date of Patent: September 30, 2003Assignee: Eastman Kodak CompanyInventor: Shinichi Yoshida
