Abstract:
An adjustable filter for suppressing radio frequency emission is disclosed. The adjustable filter comprises a ferrite material inductively coupled to a signal carrier, the signal carrier having current at a first frequency and a second frequency, and a signal carrier having an adjustable inductance for adjusting the electrical characteristics of the signal carrier. Adjusting the electrical characteristics of the signal carrier reduces saturation of the ferrite material at the first frequency, thereby allowing the ferrite material to suppress current at the second frequency, where the second frequency is higher than the first frequency.
Abstract:
Digital cameras, systems, and methods for implementing a demo mode are disclosed. An exemplary method of demonstrating a digital camera to a user may comprise activating a demo mode that displays demonstrative camera display images. The method may also comprise suspending the demo mode so that a user can try various camera settings. The method may also comprise, after a time-out, resetting the camera settings to a default state.
Abstract:
A device includes a rechargeable battery and a USB interface including a USB_ID pin. A charging device is connected to the device via the USB interface. A battery charging circuit in the device receives a charge via the USB_ID pin from the charging device, and the battery charging circuit charges the battery with the received charge.
Abstract:
A camera interface module is disclosed. The camera interface module has a first connector on one side configured to couple with a camera dock. The camera interface module has a second smaller connector on a second side configured to couple to a camera. The camera interface module has a standard input/output (I/O) connector and a power jack on a third side.
