The frustum includes a central axis with the antenna tiles disposed around the central axis of the frustum and sloping away therefrom. Each antenna tile includes opposite ends, with one end narrower than the other end. A planar array of antenna elements is disposed on each antenna tile in which the antenna elements of each array are configured to operate as a phased array. A control system connects to the planar arrays of antenna elements in which the control system is configured to selectively activate and deactivate each of the planar arrays.

Abstract: In some examples, a printing system comprises a controller to determine, during a print operation, first status information that relates to a condition of a first nozzle set of the print head, and second status information that relates to a condition of a second nozzle set of the print head. In response to determining from the first status information that a number of malfunctioning nozzles in the first nozzle set does not exceed a first threshold value and determining from the second status information that a number of redundant nozzles in the second nozzle set exceeds a second threshold value, the controller is to cause the second nozzle set including the redundant nozzles of the print head to be operated in place of the first nozzle set to continue the print operation.

Abstract: Certain examples described herein relate to printing systems and methods of operating the same. In an example of a printing system, a nozzle diagnostic mechanism obtains information relating to a condition of a first nozzle set of a print head following a first period of an established printing operation, and a nozzle compensator receives information relating to the condition of the first nozzle set from the nozzle diagnostic mechanism. Based on the received information, the nozzle compensator then causes a second nozzle set of the print head to be operated in place of the first nozzle set of the print head during a second period of the established printing operation. In an example of a method of operating a printing system, status information that relates to a condition of a first nozzle set of a print head is determined during a print production operation.

Abstract: An antenna system is provided. The antenna system includes a planar array of antenna elements configured to operate as an array having a plurality of receive (Rx) antenna elements for receiving a signal in a first frequency band and a plurality of transmit (Tx) antenna elements for transmitting a signal in a second frequency band. The Rx antenna elements and the Tx antenna elements are interleaved in a pattern such that total Tx power leakage is distributed among the plurality of Rx antenna elements. Furthermore, each Rx antenna element is provided with a high dynamic range amplifier (HDRA) for amplifying a receive signal and filtering any Tx power leakage at each Rx antenna element.

Abstract: A method and system of conducting an on-line auction of specific products of a product type so that winning bid amounts among the specific products will vary, a wide range of types of buyers will bid and the quantity offered is affected by the number of bidders. The system fixes a set time frame in which all bidding for all specific products of the product type is to occur. For a specific product of the product type a number of bids is fixed sufficient to trigger an end to bidding and offering an additional specific product of the product type. For each specific product a number is randomly selected and used to fix the starting price of the specific product. Bidders are advised the starting price for the specific product, the fixed number of bids for each specific product offered and the set time frame.
