摘要： An apparatus for detecting the presence of multiple items includes a platform upon which one or more items may be placed and a detector positioned with respect to the platform to receive an image of a profile of the one or more items on the platform. The detector is configured and arranged to generate a signal corresponding to the profile. The signal indicates whether multiple items are on the platform. The detector may be, for example, a moving point detector, a linear detector, or a two-dimensional array detector. This apparatus can be used in conjunction with an inventory control device, such as an automated library check-out device, to prevent the unauthorized removal of inventory items.

摘要： The present invention overcomes the problems discussed above by providing a linearizer apparatus for providing a linear ramp modulation for a voltage control oscillator (VCO), including voltage controlled oscillator means (VCO) having input and output terminals, and means for producing the output signal at its output terminal at the output frequency such that the output frequency corresponds to the voltage of a modulated tuning signal applied to the input terminal. A signal division means is coupled to the output of the VCO for producing a divided signal. A glass bulk acoustic delay means is coupled to the signal division means for producing a delayed signal. A first comparison signal generator means is coupled to the divided signal and the delayed signal for producing an IF signal which is proportional to the VCO output signal non-linearities. A reference oscillator means is provided for producing a reference signal. A second comparison signal generator means is coupled to the reference signal and the IF signal for producing an error signal. Finally, a summing means is coupled to a modulation waveform generator means and the error signal for producing a modulated tuning signal which is input to the VCO to frequency modulate the VCO.

摘要： Supplying pulsed current to a load involves repeatedly driving an electrical load between successive active and idle states via a regulator that includes a switched mode power supply. The regulator receives input current from a direct current power source and provides output current to at least an energy storage device in the idle states of the electrical load. The energy storage device is coupled to the load and the regulator. Output current is provided from both the regulator and the energy storage device to the electrical load in the active states of the electrical load. A storage capacity of the energy storage device is selected so that a duty cycle of the input current is greater than a duty cycle of the output current.

摘要： Non-networked radio frequency identification (RFID) systems and methods are described that use RFID tags to exchange information between non-networked RFID readers. The RFID tags may store information about conditions the RFID-tagged items have encountered while being processed. RFID readers may dynamically update the information stored on the RFID tags as the RFID-tagged items are processed at nodes. An RFID tag may include a processor that dynamically determines process control instructions based on the information.

摘要： Techniques for detecting radio-frequency identification (RFID) tags are disclosed. For example, an exit control system is described that detects unauthorized removal of articles from a protected facility. A series of antennas are setup to produce interrogation corridors located near the exit of the protected area. RFID tags are attached to the articles to be protected. Each tag includes information that uniquely identifies the article to which it is affixed and status information as to whether the articles removal from the facility is authorized. The RF reader outputs RF signals through the antennas to create electromagnetic fields within the interrogation corridors. The reader outputs RF power from a single port to the multiple antennas via a splitter/combiner. In this way, a single RF reader with only one transmitter/receiver port simultaneously interrogates multiple antennas. A variety of techniques are described by which the reader can detect the removal of an unauthorized article.
