20090009136 | RECHARGEABLE BATTERY WITH INTERNAL DISCHARGER - To shift a rechargeable battery into a lower load state that is ideal with regard to storage and aging, it is proposed that a Zener diode connected in series with a resistor and a switch. The rechargeable battery voltage, which corresponds to the predetermined, lower load state, is selected as the breakdown voltage of the Zener diode. On being started manually, the rechargeable battery is shifted to a lower load state, if the current load state is higher than the predetermined, lower load state. A digital version by means of a manually switched-on digital circuit is also proposed. | 01-08-2009 |
20090021897 | ASSEMBLY WITH A HOUSING - An assembly with a housing, having a storage cell with two electrical poles, in which the storage cell is retained in the housing, with two electric lines, and each line is connected to one of the electrical poles, and the two lines are extended to two electrical contacts, having a protection device, which is disposed in the current flow of at least one of the two lines, and the protection device is disposed outside the storage cell in the housing, and the protection device protects the storage cell against overheating and/or excess current. | 01-22-2009 |
20110042117 | ENERGY STORAGE MODULE AND POWER TOOL COMPRISING AT LEAST ONE ENERGY STORAGE MODULE - The invention is based on an energy storage module, in particular a battery pack for supplying power to a power tool. According to the invention, a plurality of cells are interconnected electrically for energy storage. It is proposed that the cells are electrochemical storage cells having a flexible cell casing that is dimensionally unstable. The invention further relates to a power tool having at least one such energy storage module. | 02-24-2011 |
20110052944 | DEVICE FOR HEATING A RECHARGEABLE BATTERY, CHARGER, AND ACCESSORY ELEMENT - The invention relates to a method for heating a rechargeable battery in which the rechargeable battery is supplied with voltage in such a way that the current flowing in the rechargeable battery heats the rechargeable battery without essentially charging the rechargeable battery. The invention also relates to a charger for carrying out the method. | 03-03-2011 |
20120022808 | METHOD AND DEVICE FOR OVERLOAD DETECTION IN BATTERY-OPERATED DEVICES HAVING AN ELECTRIC MOTOR - In a method for detecting an overload situation in a battery-operated device having an electric motor, a load current of the electric motor is ascertained and used to deduce a thermal overload of the battery in such a manner, that, starting out from a static temperature limit, a temporally variable, maximum permissible temperature limit for the battery is calculated using a specifiable function dependent on the ascertained load current. The calculated, variable temperature limit is compared to a current, measured temperature of the battery, and a thermal overload of the battery is deduced from the result of the comparison. | 01-26-2012 |

20100050003 | MONITOR POWER MANAGEMENT - A method of performing power down of a computer monitor when a video signal is no longer present and apparatus which performs the method schedules an automatic power conservation mode after a given period of time unless an inhibiting power sustain command embedded in the video signal is received. The power sustain command is placed in the regular video signal at a regular interval. The frequency of the command may be made shorter than the power-off timeout in order to maintain the power-on state of the monitor. Multiple time lapse thresholds may be set to permit multiple power conservation modes. This method may be implemented without making hardware changes in retrofitting a monitor. | 02-25-2010 |

20090022409 | Motion encoding of still images - The present invention is directed to a method and apparatus for encoding a series of still images. The first image is captured and stored, then for each subsequent image of the series, that image is captured and compared to the first image or the previous image and difference information between the first or previous image and each subsequent image of the series is stored, resulting in one output file that contains the base image and difference information for each subsequent image, thereby reducing the amount of storage needed to store a series of images. | 01-22-2009 |

20130103506 | System for Digital Yearbook with Advertising - A customized digital yearbook system includes advertisements that are inserted into each of the individual customized yearbooks. Preferably, a fee is paid by the advertisers for keeping the advertisements in the individual customized yearbooks for a period of time, which is renewable. If not renewed, in some embodiments, a new advertiser pays a fee and the advertisements are replaced with new advertisements from the new advertiser(s). | 04-25-2013 |
20140046778 | System for Digital Yearbook with Advertising - A system and method for providing advertisement in a digital yearbook includes a server and a user device for presenting media content on a display. Yearbook data is accessible by the user device and includes text and graphics pertaining to an organization and at least one advertisement. If/when the user device is connected to a network, the user device checks for a replacement advertisement and if there exists the replacement advertisement, the user device replaces one of the at least one advertisements with the replacement advertisement before the user device accesses the yearbook data. The user device presents the yearbook data and one or more of the group consisting of at least one advertisement and the replacement advertisement on the display. | 02-13-2014 |
