Abstract: A multi-rate commodity metering system comprises an electronic key containing an EEPROM, and a meter for metering the commodity and having a receptacle for receiving the key. The meter also contains a real-time clock. The key can operate as a programming device and a meter-reading device. When the key is initially inserted into the meter, it starts a billing period, eg a quarter, and if necessary programs the meter with the times for switching between rates and the prices per unit of the commodity for each rate. Towards the end of the billing period, the meter reading is entered into the key with the time and date to which it relates and a visible and/or audible warning is produced to remind the customer to remove the key and take it to the commodity supplier's premises so that the supplier can read out the meter reading from the key. If the customer fails to do this within a certain time, the supply of the commodity is cut off, although an emergency supply can be obtained for a further predetermined time if necessary.

Abstract: According to a method and apparatus for detecting defective printed matter in a printing press, each pixel data of a printed matter serving as a reference is stored as reference image data. Each pixel data of printed matter serving as a test object is input as test image data. Corresponding pixel data of the reference image data and the test image data are compared with each other to detect defective printed matter. A change in tone is recognized by accumulating and comparing the reference image data and the test image data in units of predetermined areas. The reference image data is automatically updated and stored on the basis of new test image data upon recognition of the change in tone.

Abstract: Apparatus and a method for generating a multi-level halftone image (104) from a digitally sampled continuous tone image (101). The apparatus includes a control circuit (140), a preference matrix (150) having as its matrix elements addresses of a plurality of look-up tables (160) and a plurality of look-up tables (160) in the form of a look-up table stack (155). Generally, the control circuit (140) instructs the preference matrix (150) to select a look-up table (160) from the look-up table stack (155) in a pre-defined manner. The selected table (160) is used to convert an intensity value (102) into a multi-level pixel value (106) in the halftone image (104). To accomplish the conversion, each look-up table (160) contains a quantized one-dimensional transfer function (165') having as an input the magnitude of the intensity value (102). The magnitude is mapped into an output level by the transfer function as one of a plurality of available levels. The output level is assigned a pixel location in a halftone cell (103). The look-up table selection is repeated for each element of the preference matrix (150) and the magnitude of each intensity value (102) is mapped into the halftone cell (103) to generate a multi-level halftone image (104).

A control circuit 11 is arranged to modify the DSCR (7), acquisition circuit (8) and memory interface (9) in dependence on the type of data detected. The arrangement is such that the detector is set to decode data of one type, for example teletext, and if no valid data is detected within a given period, for example four television frames, the control circuit (11) causes the decoder to attempt to decode data of the other type (VPS).
