Abstract: An apparatus for generating vertically separated atom clouds. The apparatus comprises an optical system comprising an arrangement of lenses and optics. The optical system is configured to trap and cool atoms to form a cold atom cloud; select the hyperfine level of the atoms; trap atoms of the cold atom cloud in a standing wave optical lattice; and vertically split the cold atom cloud into a high cold atom cloud and a low cold atom cloud. The splitting comprises splitting the cold atom cloud into two clouds by launching atoms of the cold atom cloud in opposite directions to form a high cold atom cloud and a low cold atom cloud, and catching the low cold atom cloud up to reach the same velocity as the high cold atom cloud.

Abstract: A single arm laser system comprising a first in-phase quadrature modulator, IQM. The first IQM is configured to receive a single frequency fibred laser beam from a frequency locked laser seed, generate a first single side-band frequency based on a carrier frequency of the single frequency fibred laser beam and suppress the carrier frequency, and output a first fibre laser beam having a single side-band suppressed carrier frequency. The single arm laser system also comprises a second IQM in line with the first IQM. The second IQM is configured to receive the first fibre laser beam from the first IQM, generate a second single side-band frequency based on the first single side-band frequency and maintain the first single side-band frequency as the carrier frequency, and output a second fibre laser beam having the first and second single side band frequencies.

Abstract: The method of managing media files remotely on a portable electronic device having the touch screen display includes storing a composite media file index that lists all media files, and their attributes, whether stored on the portable electronic device or accessible at a remote computing device. The method continues by rendering a graphical user interface for a media manager application, operable to access the stored media file index, on the touch screen display. At least one activation touch event is then detected on the touch screen display, and in response to the at least one activation touch event, a group of media files having shared attributes are displayed within the graphical user interface, and at least one media file is identified for download from the remote computing device. The at least one media file is then downloaded during synchronization of the portable electronic device to the remote computing device.

Abstract: A portable electronic device that has a housing, a moveable touchscreen display constrained by the housing, the touchscreen display including a touch-sensitive input surface overlying a display device, a single mechanical switch disposed between a back surface of the touchscreen display and a base of the housing, and operational components including a processor within the housing and connected to the touchscreen display and the single mechanical switch. The touchscreen display moves relative to the base in response to application of sufficient force to the touchscreen display resulting in actuation of the single mechanical switch. A method of controlling the portable electronic device includes providing a graphical user interface for user interaction, receiving input from the touchscreen display and the single mechanical switch, and providing output to the display device responsive to receipt of a combination of the input from the touchscreen display and the single mechanical switch.
