An image capture apparatus has a combined electronic camera and swipe scanner. The electronic camera has an optical system and detector array for remote capturing of a first image. The swipe scanner has an optical system and detector array for swipe capturing of a second image. The image capture apparatus further has a data storage arranged to store the first image and the second image in association with each other. The electronic camera may be a moderate resolution color camera, and the swipe scanner may have a grey-scale detector array capable of scanning an object at a higher resolution than the camera. A display is provided so that both images can be viewed separately in association with each other, or combined into a combination image, which has color information from the camera to colorize higher resolution pixels from the scanner.

In a wireless network containing battery powered stations, one station is designated as a control point (CP). Each of the remaining stations has two operating modes: an active mode in which it receives and transmits messages, and an inactive or sleep mode which incurs reduced power consumption. The Control Point periodically transmits a beacon signal, and each station switches to its active mode to receive at least some of these beacon signals. A beacon signal may indicate that data is available for transmission to a particular station (from another station), in which case that particular station then broadcasts a message to indicate that it is awake and can receive messages. A beacon signal also indicates whether a broadcast period is in progress, and time to elapse until a next possible broadcast period will commence; if the Control Point has previously received and stored any broadcast messages it will re-broadcast them during the next following broadcast period and the remaining stations will react by remaining in active mode for the duration of that period.
