Abstract: A substantially pocket-sized portable control device for a digital camera, comprising: a camera interface unit, a display unit for displaying images received from the digital camera, a control unit for defining control parameters for sending to the digital camera, and a user interface, for obtaining user input for applying settings to the control unit. The device allows screen-based data input (e.g. via stylus). Conveniently the device is a cellular telephone or a personal digital assistant.

Abstract: An image capture apparatus creates multiple exposure images by combining raw sensor output data prior to other image processing. The apparatus consists of a sensor for capturing current raw image data and an image combiner. The image combiner forms a multiple exposure image by linearly combining stored raw image data with current raw image data from the sensor.

Abstract: A local net area network, or LAN, configuration is provided with a multiple generic LAN channel architecture which can be logically and dynamically changed. The configuration control can be applied to each module of the network and to each port of a module of a LAN hub. The architecture provides multiple LAN protocols to be used simultaneously, as needed, through protocol specific functions. Industry standard protocol such as: token bus, token ring, and fiber distributed data interface (FDDI), can be implemented using the generic channel architecture and its characteristics providing respective network functions. The architecture also provides a digital collision detection method and provides information necessary for precise network statistics monitoring. The token passing ring architecture provides a logical ring formation within the generic channel. A token passing bus architecture uses modified Ethernet.TM.

Abstract: A method and apparatus for providing secure communication on open networks. Each port of the network is provided with a security entity which monitors the communication between one port to the other. End stations connected to the ports communicate with other end stations by transmitting data to the port and receiving data from the port. The data is sent out in data packets with a destination address and a source address. Each port has its own unique address. The security entity checks data packets coming into the port for a destination address. The destination address of incoming data packets is compared with the port address of the affiliated port. Also, outgoing data packets from an end station to a port are also monitored by the security entity. The security entity compares the destination and source address of the data packet with the affiliated port address.
