Abstract: A method for maintaining incremental backups of a file. The method includes identifying a target file to be backed up. The method also includes comparing the target file to a one or more previously backed up files, in order to identify differences of the target file from a corresponding previously backed up file. The method also includes generating a delta version of the target file that records the identified differences from the previously backed up file.

Abstract: A wireless hands-free mobile audio device is provided for wirelessly connecting an electronic device with at least one headphone speaker for transmitting audio signals therethrough, essentially transforming any set of headphones into a wireless headset. The mobile audio device comprises a housing having a wireless interface for connecting with the electronic device, and an audio output port for transmitting audio signals received by the mobile audio device from the electronic device to at least one earpiece or speaker connected thereto. The mobile audio device can also include a pre-attached earpiece component in addition to the separate audio output port permitting use of the device either by attaching a standard set of headphone to the housing or attaching a singular earpiece for use with the pre-attached earpiece component where audio signals are simultaneously transmitted to the pre-attached earpiece and the audio output port.

Abstract: A speaker device for hands-free operation of a mobile device includes a first assembly operable for wireless communication with a mobile device, and a second assembly with a receptacle for docking at least a portion of the first assembly. The first assembly includes a first speaker and a first microphone, while the second assembly includes a second speaker. When the first assembly is docked in the receptacle of the second assembly, the mobile device is connected in wireless communication with the second speaker, and when the first assembly is removed from the second assembly, the mobile device is connected in wireless communication with the first speaker.

Abstract: A portable power charger having an internal rechargeable battery is provided with a power connection port than can act in a power input mode when the charger is connected with an external power source via the power connection port and in a power output mode when at least one electronic device is connected to the charger via the power connection port. The power charger may be connected with both an external power source and an electronic device via the power connection port at the same time, wherein the charge supplied from the external power source recharges the charger and any electronic device connected to the charger. The charger also can automatically turn on if a connector cable is connected to the power connection port with either an external power supply or an electronic device connected at the other end of the cable to supply or draw power through the cable.

Abstract: A portable charger is provided for charging one or more electronic devices simultaneously from a rechargeable internal battery. To accommodate multiple electronic devices, a portable charger unit is combined with multiple connectors for connecting to more than one electronic device, as necessary. For example, the charger unit can include at least one power output for connection to electronic devices via connectors or charging cables, including a squid connector providing multiple connection interfaces adaptable to a variety of electronic devices. Alternatively, the charger unit can include two or more connector cables connected to the charger unit and stored within the charger housing for connection to electronic devices when needed. An adapter unit is provided for connection to the charger unit for recharging the internal battery of the charger unit.

Abstract: Systems and methods for simultaneously providing local data backup and online data backup. A local backup device is programmed with an application, which allows a user to connect a client device to the local backup device and to an online backup service so that data backup can be done simultaneously to the local backup device and to the online backup service.

Abstract: A locating device for attaching a fixture level on a wall is disclosed. The device includes an elongated body having a rear side. A first trammel is slidingly mounted on the elongated body and includes a first marker extending from the first trammel in a direction away from the rear side of the body. A second trammel is also slidingly mounted on the elongated body and includes a second marker extending from the second trammel in a direction away from the rear side of the body. A first securing device is attached to the first trammel to secure it in a desired position. A second securing device is attached to the second trammel to secure it in a desired position. A level is mounted to the elongated body and has a predetermined orientation relative to an imaginary line connecting the first marker and the second marker. A side of the elongated body may include graduated markings which can be used as a guide to position the trammels.
