US Patent:

6888502, May 3, 2005

Filed:

Mar 5, 2002

Appl. No.:

10/093202

Inventors:

Michael L. Beigel - Encinitas CA, US
John R. Tuttle - Boulder CO, US
H. Clark Bell - Chatsworth CA, US

Assignee:

Precision Dynamics Corporation - San Fernando CA

International Classification:

H01Q001/38

US Classification:

343700MS, 343718, 3405727

Abstract:

An identification appliance, such as a wristband, bracelet, patch, headband, necklace, card, sticker, or other wearable appliance, has an improved patch or microstrip antenna. The microstrip antenna comprises a conductive patch layer, a conductive ground layer and a dielectric layer in between the conductive layers. The microstrip antenna is mounted to or disposed in the identification appliance, where preferably the ground layer is closest to the user and the patch layer is furthest from the user. Electronic circuits may be located in the dielectric layer, on a surface of a conductive layer, or on another part of the identification appliance. Connecting holes through the dielectric layer may allow circuits to be connected to a conductive layer or layers. This improved antenna resolves detuning and communication degradation problems.

International Classification:

G06K 19/06

US Classification:

235492, 235486, 235375

Abstract:

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.

Appl. No.:

11/458459

Inventors:

Michael L. Beigel - Encinitas CA, US
John R. Tuttle - Boulder CO, US

Assignee:

Precision Dynamics Corporation - San Fernando CA

International Classification:

G08B 13/14

US Classification:

3405721, 3405727, 340 1033

Abstract:

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.

Assignee:

Precision Dynamics Corporation

International Classification:

G05B019/00
H04Q001/00

US Classification:

340/010420, 340/005610

Abstract:

An identification appliance such as a wristband, headband, armband, ankleband, or legband which has a wireless communication circuit to communicate with a system, network, or device. The identification appliance preferably communicates with a Bluetooth local network and may issue or receive commands or data including voice data. An example command is to expand privileges given to the user of the identification appliance, such as entrance into a restricted area. The information appliance may broadcast its location via a Global Positioning System and have voice activation or speech recognition. The appliance may provide information about the authorized bearer such as his name, address, phone number, passport number, driver's license data, social security number, credit card information, fingerprint data, biometric voice characteristics, retinal characteristics, medical data and so on.
