Abstract: A data processing apparatus for performing rounding on an input value to produce a rounded form output value includes floor calculation circuitry that receives the input value in redundant-representation and generates two candidates of a floor of the input value in non-redundant representation. Ceiling calculation circuitry receives the input value in redundant-representation and generates two candidates of a ceiling of the input value in non-redundant representation.

Abstract: A service provider system remembers feedback by a user when the user selects an offer, a presented option, or other content from a page or display on a user device. The user is then taken to a new page or screen with details about the offer, option, or other content. When the user goes back to the original page or screen, the page is revised based on the user feedback. For example, a dialog box may pop up over the selected offer to ask the user whether the user accepted the offer or is not interested in the offer. If so, the offer disappears and subsequent pages may not show the selected offer again.

Abstract: A data processing apparatus is provided to perform a digit-recurrence division operation to determine a quotient as a result of dividing a dividend by a divisor. Scaling circuitry scales the dividend and the divisor by a factor to produce a scaled dividend and a scaled divisor. Digit recurrence circuitry performs one or more iterations of the digit-recurrence division operation on the scaled dividend and the scaled divisor, with each iteration producing a digit of the quotient and a remainder value. The remainder value is provided as an input to the digit recurrence circuitry for a subsequent iteration. Initialisation circuitry performs a first iteration of the one or more iterations and provides the digit of the quotient after the first iteration. The initialisation circuitry receives, as an input, an intermediate value produced by the scaling circuitry while scaling the dividend.

Abstract: A broccoli banding machine having an electric DC motor drive actuated by an interrupted optical beam is disclosed. The banding machine includes a plate with a central aperture defining a depending cylinder. The depending cone has a light beam looking across the cylinder which when interrupted keeps arms having band engaging fingers in the band expanded position. Both arms and fingers are mounted above the supporting plate where access and view of arms by the banding and packing worker is provided at all times. Upon gathering broccoli to a bouquet with both hands, the worker places the stalks of the gathered bouquet into the cylinder, interrupting the light beam. Upon such interruption, the arms at the band engaging fingers are cycled into the bunched stalks, the contracted band released to the stalk, the bouquet at the stalks removed from the vicinity of the fingers, and a new rubber band placed upon the centrally disposed fingers.
