20140182378 | ENERGY HARVESTER POWERED ACCELEROMETER - A sensor may include a base, a resonator centered over the base, and an accelerometer disposed in a base of the resonator. The resonator may be configured to harvest energy from vibratory motion of a host device and includes a slot disposed on a center rectangular plane of the sensor. The sensor may include a circuit arrangement disposed on the accelerometer and in the slot on the center rectangular plane of the sensor. A piezoelectric element may be mounted on the resonator and electrically coupled with the circuit arrangement. The piezoelectric element may be configured to convert vibratory energy of the resonator to electrical energy. An optional antenna may be coupled with the circuit arrangement and configured to wirelessly transmit data from the sensor to a receiving station. | 07-03-2014 |
20140184024 | MONOLITHIC ENERGY HARVESTING SYSTEM, APPARATUS, AND METHOD - An energy harvesting device utilizing a monolithic, mesoscale, single-degree-of-freedom inertial based resonator in which the support structure, beam-spring, and proof mass are a single component without joints, bonds, or fasteners. Frequency tuning features include holes in the proof mass in which mass can be added to change the devices resonance frequency as well as levers which add curvature to the beam-spring system and adjust system stiffness. Robustness is increase by designing the resonator to exhibit nonlinear behavior such that its power density is maximized for low vibration amplitudes and minimized for high amplitudes. The device structural resonance modes are designed to be much higher than the resonators proof mass-spring resonance frequency. Electromechanical transducers are used to convert the resonators mechanical energy to electrical energy. Electrical circuitry is included to extract and condition the electrical charge. | 07-03-2014 |
20150241463 | VIBRATION SENSOR - A sensor may include a base, an accelerometer rigidly coupled with the base and centered over said base, a circuit arrangement electrically coupled with the accelerometer, and a battery rigidly held in contact with the circuit arrangement and centered over said accelerometer and said base. The base is configured to be secured to a host structure, and the circuit arrangement is configured to receive signals from the accelerometer. | 08-27-2015 |

20100145942 | SYSTEMS AND METHOD FOR MAPPING LARGE OBJECT DATA CONTENT IN A DATABASE TABLE TO A WORK AREA - According to some embodiments, a programming language in an application server may include access to different database server implementations, wherein the programming language accesses content of database tables via work areas derived from the database tables. A database table, having columns to store content, each column being associated with a column type, may be mapped to a work area such that, at a database server, each column in the database table is mapped to a corresponding component of the work area, the corresponding component having a default component type based on the column type of the associated column in the database table. It may be determined that a particular column in the database table is to store large object data content, and, in response to the determination, a new mapping to a work area may be defined such that the particular column maps to a corresponding component having a component type other than the default component type. | 06-10-2010 |
20120096050 | SYSTEMS AND METHODS FOR MAPPING LARGE OBJECT DATA CONTENT IN A DATABASE TABLE TO A WORK AREA - According to some embodiments, a programming language in an application server may access different database server implementations, wherein the programming language accesses content of database tables via work areas derived from the database tables. A database table may be mapped to a work area such that each column in the database table is mapped to a corresponding component of the work area (having a default component type based on the column type of the associated column). It may be determined that a particular column in the database table is to store large object data content, and a new mapping to a work area may be defined such that a particular column maps to a corresponding component having a component type other than the default component type. | 04-19-2012 |
20130159247 | CHANGE DATA CAPTURING DURING AN UPGRADE - In one general aspect, a computer system can include instructions stored on a non-transitory computer-readable storage medium. The computer system can include a logging table generator configured to generate a logging table corresponding with an original table targeted for an upgrade, and a control table generator configured to generate a control table configured to store a version identifier for changes logged in the logging table. The computer system can include a change recorder configured to receive an indicator of a change to a record of the original table during execution of at least a portion of the upgrade of the original table, and a key recorder configured to store in the logging table a primary key identifying the record of the original table and the version identifier stored in the control table. | 06-20-2013 |
