Abstract: Energy conversion is provided. An energy conversion device can include one or more power delivery interfaces. The energy conversion device can include a pre-charge circuit configured to charge a capacitor to an operating voltage. The energy conversion device can include a user accessible interface configured to provide energy to the pre-charge circuit. The pre-charge circuit can charge the capacitor associated with the one or more power delivery interfaces. The user-accessible interfaces can include a direct current (DC) input. The user-accessible interfaces can include an alternating current (AC) input.

Abstract: A barcode-reading device can send barcode images to a remote server for decoding. A decoder on the remote server can process the images and attempt to decode any barcodes in the images. Once the decoder on the remote server has successfully decoded a barcode, the remote server can send the decoded data back to the barcode-reading device and/or to a host computing device that is communicatively coupled to the barcode-reading device. If the barcode-reading device receives the decoded data, the barcode-reading device can forward the decoded data to the host computing device. In some embodiments, a barcode-reading device can send all captured images to the remote server. Alternatively, a barcode-reading device can send only some captured images to the remote server. In some embodiments, a barcode-reading device can be configured to perform one or more preliminary processing operations on an image before sending the image to the remote server.

Abstract: Embodiments are directed to a method of performing incremental block based backups for volume and sub-file level backups by providing a change block tracking driver component, maintaining a context of the change block tracking driver as a driver context using a single bitmap that represents the volume being tracked, and maintaining the bitmap as the only element to track changes across the volume backups and multiple application backups involving different sub-file level backups.
