20100276999 | SPRING-POWERED EMERGENCY ELECTRICAL SUPPLY - An emergency power system for operation during loss of power on power mains comprises a spring-driven energy storage unit (ESU) and a generator. The ESU enters a generator mode responsive to a power outage state of a power sensor, during which mode unwinding of the spring drive powers the generator. After power is restored to the mains, a preferred embodiment automatically rewinds the spring using the generator as a motor. | 11-04-2010 |
20100284747 | WATER-FILLED BUILDING BLOCK FOR TEMPORARY LEVEE - A hollow block in the form of a rectangular parallelepiped when filled with water, is joined with a plurality of similar water-filled blocks to form a flood barrier. Two opposite sides of each block have connection features that connect with features on the first and third sides of adjacent blocks to form a wall of connected blocks. Top and bottom walls of each block each have an inter-tier connection feature that mates with a block in each adjacent top or bottom wall. Each block includes on each of its top and bottom walls, inter-tier connection features structured to mate with an inter-tier connection feature of a similar block in the adjacent tier. | 11-11-2010 |
20110019939 | BAG FOR HANDHELD ELECTRONIC DEVICE - A bag for enclosing a handheld electronic device (HED) comprises a flexible sheet material such as a flexible or stretchy fabric. The material is formed into a bag having a main body and a mouth. The mouth has a periphery smaller than the periphery of the main body. The mouth can elastically stretch to allow passage of the HED. First and second loops are attached to and project from the bag adjacent to the mouth to allow a user to support the bag with thumb and forefinger while inserting the HED. In one embodiment, an elastic structure comprises the periphery of the mouth. The unstretched length of such an elastic structure may be adjusted to compensate for the size of the HED. | 01-27-2011 |
20110318104 | TEMPORARY WATER BARRIER STRUCTURE - A structure for forming a barrier for an adjacent level of water comprises a plurality of “A” panels and a plurality of “X” panels. The A panels have at least two slots each extending from one of first and second long edges of the A panel to a slot terminus between the two edges. The X panels each have at least two slots each extending from an intersection with one of first and second edges of the X panel to a slot terminus between the two edges. Placing the X panels in a crossed and interlocked relationship with the A panels forms four sides of at least one cell. A container filled with water is within each of the cells. The container is formed of flexible material impervious to water and defining a closed volume having an unstressed shape approximating that of the cell's four sides. | 12-29-2011 |
20120229324 | HUMAN PRESENCE DETECTOR SUITABLE FOR CONCEALMENT AND USING A SHAPED MICROWAVE BEAM - A presence detector unit (PDU) of the type relying on microwave radiation provides a signal indicating movement within a defined space when such movement occurs. A source of microwave radiation within a housing projects a beam of microwave radiation directed through a side of the housing to suffuse at least a portion of the defined space. A detector within the housing senses changes in microwave radiation reflected back toward the detector. An adjustable beam occlusion structure is supported by the housing and blocks a portion of the microwave radiation emanating from the source and through the side of the housing. | 09-13-2012 |

20090067087 | APPARATUSES AND METHODS FOR PRE-ERASING DURING MANUFACTURE OF MAGNETIC TAPE - The present invention relates to direct current (“DC”) pre-erasing servo channels of a magnetic tape prior to writing servo data in a servo channel. The present invention particularly relates to those servo recordings which were written with a uni-polar current waveform. The DC pre-erase is performed using a uni-polar direct current of a polarity that is opposite to the polarity of the direct current used to write the servo data. This pre-erase may be done with one or more heads. Also, as will be described, the pre-erase of a servo channel and writing to a servo channel may be done by making two passes over a single head or by using two or more heads to perform both steps. Also, it is within the scope of the present invention to have the heads mounted on a single mount or have the heads on separate mounts and on separate tape decks. | 03-12-2009 |
20090147399 | MAGNETIC MEDIA FORMATTED WITH AN INTEGRATED THIN FILM SUBGAP SUBPOLE STRUCTURE FOR ARBITRARY GAP PATTERN MAGNETIC RECORDING HEAD - An arbitrary gap thin film magnetic recording head is fabricated by forming a substrate based on traditional vertical planar thin film head wafer technology which is designed to produce an integrated subgap and subpole substrate structure. The wafer is then processed into row bars to reveal, in a plane parallel to the transducing direction of the medium, the subgap and subpoles at the surface of the row bar and to bring the structure to a certain coil depth or gap depth. A flat or cylindrical contour may be utilized. | 06-11-2009 |
