Abstract: A panoramic optical device includes a quadric reflector, a mirror, and a set of one or more optical elements. The quadric reflector has a conical shape, which tapers from a wide base to an apex. The apex includes an aperture. The mirror is positioned within the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror reflects environmental light that is reflected by the quadric reflector into the aperture or reflecting light emitting from the aperture onto the quadric reflector. The set of one or more optical elements are positioned at least partially within a volumetric region of the quadric reflector. The one or more optical elements focus light passing through the aperture.

Abstract: A stereographic image associated with a panoramic camera can be identified. The panoramic camera can include of a set of lenses and an image sensor. A pixel degradation curve associated with the image and/or the hardware of the panoramic camera can be determined, as can a sensor geometry of an image sensor used by the panoramic camera. A fixed smoothing function based on the pixel degradation curve and/or the sensor geometry can be created. The fixed smoothing function can be applied to a stereographic image to modify the image so it includes substantially uniform image detail per image region.

Abstract: A system (20) of targeted broadcasting in a cellular communication system during an event can include at least one mobile unit (25) having stored therein scheduling information relating to an event, a designated location for the event, and a designated group channel for monitoring such event. The mobile unit can further be programmed to monitor (67) for the event in a designated location and on a designated group channel during a predetermined time window and receive (71) a targeted message during the event on the designated group channel if a current location of the mobile unit matches the designated location stored. The mobile unit can be programmed to transmit at least one group call message response in response to receiving the group call message only when the mobile unit is in the designated location. The system can further include fixed network equipment (26) that transmits data related to the event.
