Filed:

Jul 2, 2004

Appl. No.:

10/884429

Inventors:

John C. Greene - Allen TX, US
Krishna Doddamane - Dallas TX, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H03M007/12

US Classification:

341 70, 342 42

Abstract:

A method and apparatus for accurately decoding a Manchester data stream having transition time distortion and noise spikes. Briefly, in an embodiment using a protocol where a falling edge at the mid-point of a bit represents a “1” bit and a rising edge at the mid-point represents a “0” bit, the coded data can be accurately determined by comparing the time period tpfrom the start of the bit to the first falling edge and the time period tpfrom the last rising edge to the end point of the bit. If tpis less than tp, the bit represents a bit value of “0” and if tpis less than tp, the bit represents a bit value of “1”.

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H04J 15/00

US Classification:

370241, 375340

Abstract:

Circuitry and method for receiving and decoding a data stream without a preamble transmitted from the transmitting device. The invention includes circuitry in the receiver or interrogation unit for generating a simulated preamble signal that is provided to the input of an averaging circuit and a comparator. The averaging circuitry then averages the simulated preamble signal and the actual received data signal to avoid loss of messages and information data at the front end of the received signal from a transponder.

John Clay Greene - Allen TX, US

Assignee:

Maxim Integrated Products, Inc. - Sunnyvale CA

International Classification:

G08B 21/00

US Classification:

340 101, 340 102, 340 103, 3405721, 342 42, 342 44, 342454

Abstract:

Embodiments of the present invention provide RFID systems having a centralized frequency source and controller. The centralized frequency source generates a reference signal, having a frequency below the RF band of interest, which is transmitted to a plurality of reader nodes. The centralized controller generates and transmits data to the plurality of reader nodes. At each reader node, the reference signal is converted to an RF carrier signal that is modulated and transmitted within corresponding read field of the reader node. This modulated RF carrier signal may interrogate and communicate with one or more RFID tags within this read field. The RF carrier signal may also be held constant to enable communication from RFID tags to the reader node, which is subsequently transmitted back to the centralized controller or processor.

International Classification:

H02J 7/00
H02J 7/02

Abstract:

A charging energy control system may include an implantable medical device (IMD) and an external charger. The IMD receives charging energy to recharge the battery during a charging energy acceptance period and rejects the charging energy during an actual charging energy rejection period. The external charger transmits the charging energy to the IMD in order to recharge the battery. The external charger may include a charging controller configured to determine the charging energy rejection period, and regulate the charging energy during which the charging controller predicts a predicted charging energy rejection period of the IMD based on the actual recharging energy rejection period. The charging controller is configured to cease or reduce transmission of the charging energy during a charging energy conservation period that is at least a portion of the predicted charging energy rejection period.
