Abstract: The subject invention relates to a system for reading from and for writing data into electronic tags which may be associated with objects which are moving with respect to an interrogator, or may be located in fixed positions in the path of a moving interrogator. The interrogator, which is stationary if the tag is moving, sends a continuous RF signal to the remote tag. The tag backscatter-modulates the received RF signal with data temporarily or permanently stored in the tag, including, for example, data associated with the object to which the tag is attached, for example, its identity or contents. 
     The system of this invention uses a very efficient encoding technique for the data which is backscatter-modulated by the tag and received by the interrogator. The backscatter-modulated signals are made up of signals of first and second frequencies f₁ and 2f₁, respectively, where the second frequency 2f₁ is twice the first frequency f₁, and where one of the two binary bits ONE and ZERO is represented by one-half period of a signal of the first frequency followed by one period of the second frequency, and the other of the two binary bits is represented by one period of a signal of the second frequency followed by one-half period of a signal of the first frequency. The signals also contain FRAME MARKERS made up of five periods of frequency 2f₁ followed by one-half period of frequency f₁. 
     The WRITE-by-RF signals sent to the tag by the interrogator are made up of pulses of three different frequencies, one being frequency f₂, the next 2f₂ and the third 4f₂. Either a ZERO or a ONE can be one period of pulses of either 2f₂ or 4f₂ with the other bit being the other frequency, and with the FRAME MARKER being one period of frequency f₂. The MODE signal is four periods of frequency f₂.

Abstract: 2.1 A known apparatus does not take account of the influence of an excess pressure control valve, which is present up to the operating point of the excess pressure control valve, with the result that the apparatus is inaccurate. 2.2 The new apparatus therefore has the features that, in the case of a known pressure control valve, a diaphragm chamber (13) is connected to the gas-filled tank space (1) during the rest position of the piston (3) via a conduit (8 or 16) and can be hermetically sealed during the movement of the piston (3) by a shut-off valve (15) in this conduit (8) and acts as a gas spring in relation to the movement of the diaphragm. 2.3 As a result, the new apparatus makes possible measurement of the fuel level irrespective of the pressures prevailing in the gas-filled tank space before the measurement. A preferred embodiment makes it possible to avoid the induction of fuel vapour into the intake pipe of the internal combustion engine during the measurement, which previously led to a change in the air/fuel ratio and excluded short measuring times. The new apparatus makes possible a test of the tightness of the fuel tank, for example in the context of on-board diagnosis. <IMAGE>

Abstract: An electronic apparatus having a TFT LCD (37) includes a detector (41, 47) for detecting whether or not display data in a video RAM (25) is rewritten. When a rewrite operation of display data is detected, a display controller reads out display data from the video RAM, and supplies the readout display data to the TFT LCD. When data on a memory plane for storing display data, which is being displayed on the TFT LCD, is rewritten, the display controller (24) reads out display data from the video RAM, and supplies the readout display data to the TFT LCD. When display data to be written in the video RAM is the same as the already stored display data, the display controller does not supply the display data from the video RAM to the TFT LCD. When no access to VRAM is made, the display controller is set in a sleep state.

Abstract: Disclosed is a method of controlling an industrial process. This process has a plurality of states and is controlled by a client-server multi-processor control system operating in a windowed, multi-tasking, multi-thread environment. The control method starts by detecting an anomalous state of the industrial process and displaying a modal alert event box corresponding to the anomalous state of the industrial process. The process further generates an alerts pending indication in maximized applications window which displays as long as any alerts corresponding to anomalous states remain unresolved. In further embodiments, the process generates a pending alerts window listing all unresolved alerts corresponding to anomalous states of the industrial process; and an alert detail window corresponding to the unresolved anomalous state of the physical system.
