  • Customizable Mechanically Programmable RFID Tags
    Publication number: 20090058599
    Abstract: A system and method to track a status an item, or steps in a process, via one or more mechanical modifications to an RFID tag. In one embodiment, a plurality of tearable strips are attached to the tag, each strip having an electrical conductor. Each tearable strip may receive a visual or tactile indicia, such as text, a color code, a graphic symbol, or a tactile indicator (such as Braille) to assign a meaning to the strip, where the meaning is associated with the status or condition of the item, or the stage, step, or status or the process. By tearing some strips or all strips, a desired bit pattern may be programmed into a register of the RFID tag. The bit pattern may reflect the status or condition of the item, or the stage, step, or status of a process.

  • Methods and systems for the negotiation of a population of RFID tags with improved security
    Patent number: 7497384
    Abstract: Methods and systems for the negotiation of a population of RFID tags with improved security is provided. In one aspect, tags are singulated without using information that directly identifies the tags in the tag population. A key is generated to identify each RFID tag of the population of RFID tags. The generated key does not include bits identifying an item with which the particular RFID tag is associated. An algorithm is operated to identify one or more tags in the population of RFIDs tags using the generated keys. In another aspect, frequency hopping and/or spread spectrum techniques are used to provide improved security while negotiating tags. In another aspect, the reader causes the tags to scroll series of bits back to the reader for each bit sent to the tags to provide improved security.

  • Monitoring scan mirror motion in electro-optical readers and image projectors
    Patent number: 7497578
    Abstract: Crosstalk between a drive coil and a primary feedback coil is eliminated by positioning a secondary feedback coil in proximity with the drive coil for contamination by the crosstalk to the same extent as the primary feedback coil, and by processing feedback signals generated by the feedback coils to cancel the crosstalk. The drive coil is used to oscillate a scan mirror employed in an image projection arrangement or an electro-optical reader.

  • System and method for authenticating a battery
    Patent number: 7498766
    Abstract: Described is a system and method for authenticating a power source. The system comprises a battery including a first encryption engine storing a first key, and a battery charger including a microcontroller and a second encryption engine storing a second key. When the microcontroller detects a coupling of the battery to the charger, the microcontroller issues a challenge to the first encryption engine and the second encryption engine. The first encryption engine generates a first response as a function of the challenge, the first key and a predefined algorithm, and the second encryption engine generates a second response as a function of the challenge, the second key and the predefined algorithm. The microcontroller compares the first and second responses to authenticate the battery.

  • Thermal Management within Mobile RFID Readers through the Application of Temperature Governed Variable Non-Emissive Intervals
    Publication number: 20090052105
    Abstract: A thermal management system and method to control temperature in an RFID reader is described herein. In particular, by inserting variable periods of inactivity (or latency) at the beginning or at the end of each read cycle, proportional to an instantaneous temperature value of the RFID reader, over-heating and damage of RFID reader electronics is prevented. The RFID reader includes a thermal sensor and determines when the high power RF electronics is enabled. If the RFID reader is in an over-heated condition, it can be turned OFF and during this period any requests received on an interface to the RFID reader to perform a read of tag(s) are not processed.

  • Software method utilizing caller ID for maintaining connectivity during communications over distinct wireless networks by mobile computer terminals
    Patent number: 7492755
    Abstract: A method of maintaining communications between a mobile, wireless terminal and a base station of a wireless local area network is performed by determining at the base station, that communications between the base station and the terminal over a first channel on the wireless local area network has been impeded; and placing a telephone call to the terminal over a separate, distinct, second channel on a public switched telephone network. The caller ID of the incoming call is then used to verify the authenticity of the base station. Further communications continue over the second channel on the telephone network.
