Patent number: 7342360Abstract: A handheld flashlight includes a head that pivots relative to a body. Three legs pivotally connect to the body and open into a tripod to support the head in an elevated position. The legs are spring-biased toward the open tripod position and are selectively held closed by a detent mechanism. In the closed position, the legs form a flashlight handle that is aligned with an illumination direction of the head and is shaped and sized to be held in the hand of an operator. Each of the three legs contain battery source holders for battery sources that connect to each other in parallel. Diodes are disposed in series with each battery source to prevent the parallel battery sources from discharging each other.Type: GrantFiled: October 20, 2004Date of Patent: March 11, 2008Assignee: The Stanley WorksInventors: Gary Van Deursen, Michael Kwok Ying Chan

Publication number: 20070243423Abstract: A non-directional connection module is described for connecting with a battery. The non-directional connection module uses a first conductive element to connect the positive pole of the battery, and a second conductive element to connect the negative pole of the battery. An insulation element is positioned between the first conductive element and the second conductive element. Both the second conductive element and the insulation element have respective holes. The positive pole of the battery can pass through the holes, but the negative pole of the battery cannot pass through the holes. In this light, the present invention uses the non-directional connection module to connect the battery so that there is no consideration of the positive or negative poles of the battery.Type: ApplicationFiled: December 8, 2006Publication date: October 18, 2007Inventor: Chin-Hsin Ho

Patent number: 7193389Abstract: An electronic apparatus includes a housing part in which a battery is housed and a body-side connector for connecting the battery housed in the housing part to an apparatus body. When a battery-side connector connected to the battery through a connecting cable is connected to the body-side connector, the battery is connected to the apparatus body. A label is affixed on the body near the body-side connector. Provided on the label is a connector-connection indication which indicates an orientation of the battery-side connector to be connected along with a battery-housing indication which indicates a shape and a housing orientation of the battery to be housed in the housing part. This provides a guiding indication easy to view and understand, allowing a smooth, correct connection between the battery and the apparatus body through the connectors.Type: GrantFiled: April 11, 2005Date of Patent: March 20, 2007Assignee: Brother Kogyo Kabushiki KaishaInventor: Hakudai Kondo
