A system for location of animals and/or objects in an environment includes a signal processing and signal generation system consisting of electromagnetic tags on animals (or other objects) in an environment (typically a three dimension outdoor natural environment) where the animals or objects are physically present at arbitrary locations, and an electro-magnetic signal generating, signal receiving, and signal processing system that can move through or in relation to the environment. The system can compute the location and identity of the animals or objects based on signals received from their associated tags, including the calculated location of the ID tags, which function as 'Reader-Locators.' The calculated location is enhanced by information about the environment provided by maps, satellite photos, GPS, GIS and/or other data specific to the probability of the location of the animals or objects within certain regions of the environment. The system includes a physical and electromagnetic modeling operation that is interactive with the environmental information derived from the actual environment, either historically or in 'real-time' as the monitoring process occurs.

System for location in environment and identification tag

The electronic identification system provides two-way communications between reader and tags using alternating magnetic fields established by the reader and tag. Communication is accomplished by utilizing either a one-step or a two-step modulation process in which the information to be communicated either modulates an alternating magnetic field directly or modulates a periodic signal which modulates an alternating magnetic field. The coil in the reader that is used to establish an alternating magnetic field is transformer-coupled through capacitors to a push-pull driving circuit consisting of four field-effect transistors connected in a bridge arrangement. The coil, capacitors, and coupling circuitry are maintained in a tuned condition by continually adjusting either the driving frequency, the coil inductance, or the capacitor capacitance during communications. A tag utilizes a coil to couple with the reader's alternating magnetic field and a capacitor to resonate the coil, thereby extracting power from the field more efficiently. Transformer coupling of the coil and capacitor is utilized for improved impedance matching. The coil, capacitor, and coupling circuitry can be maintained in a tuned condition by continually adjusting either the coil inductance, or the capacitor capacitance during communications. Certain configurations of the system may require that tuning maintenance be discontinued during the transmission of data.

Electronic identification system with improved sensitivity

The Source-Dependent Instrument is a signal processing and signal generation system that uses one or more signal event generators that can be functionally activated and controlled by the analysis of an external input signal. These output generators and signal processors can be set to re-synthesize aspects of the input or synthesize a more complex or perceptually shifted output based on the input.

Source-dependent acoustic, musical and/or other instrument processing and feedback system

An improved radio frequency identification (RFID) tag and related reader system and process are provided, wherein the RFID tag includes an on-board battery for enhanced signal transmission range, relatively rapid signal transmission speed, and optimized completion of a data transaction between the tag and a reader. The RFID tag further includes a power management system for activating the tag battery on an as-needed basis, and for thereupon enabling limited portions of the tag circuitry as required for a specific communication protocol, thereby conserving battery power and prolonging battery service life. In one preferred form, the battery is integrated with an antenna structure of single or dual mode with respect to frequency or type. This combination battery-antenna may be designed for recharging from a source of ambient energy.

Semi-active RFID tag and related processes

An enhanced identification appliance, such as a wristband, bracelet, patch, headband, neckband, ankleband, legband, card, sticker, or other wearable appliance, may have a biometric, chemical, optical, heat, pressure, humidity, electromagnetic, and/or acoustic sensor, various opto-electronics and/or various security features such as tamper-evident and tamper-resistant features. The sensors may obtain wearer-related information such as a fingerprint, retina, iris, blood, DNA, genetic data, voice pattern, temperature and other characteristic. Security features include a fastener on the identification appliance, which indicates whether the appliance has been attached to a wearer and if so, enables circuit functions. If one tampers with the appliance, circuit functions may be disabled, certain data erased, and/or evidence of tampering made apparent. The appliance may monitor the location or determine the identity of vehicle passengers for an airplane, train, boat, bus, etc. Alternatively, the identification band may contain a person's immigration status.
