Abstract: A portable data device employs an integrated circuit having a signal processor that receives a power signal from an external source via a power node. A decoupling device is placed between the power node and the signal processor. An energy reservoir is placed in parallel with the signal processor, which acts in concert with the decoupling device to isolate the effects of the signal processor from the rest of the integrated circuit.

Abstract: Reliable communication is provided by a radio frequency identification system comprising at least one of an interrogator (102) and a transponder (104). The interrogator (102) transmits a plurality of interrogator frames (106) and receives at least one of a plurality of transponder frames (114). The transponder (104) transmits the plurality of transponder frames (114) and receives at least one of the plurality of interrogator frames (106). Each frame in the plurality of interrogator frames and the plurality of transponder frames includes an initialization sequence (108 and 116), at least one information sequence of a first predetermined length (110 and 118), and a check sequence of a second predetermined length (112 and 120) for each information sequence.

Abstract translation: 可靠通信由包括询问器（102）和应答器（104）中的至少一个的射频识别系统提供。 询问器（102）发送多个询问器帧（106）并接收多个应答器帧（114）中的至少一个。 应答器（104）传送多个应答器框架（114）并接收多个询问器框架（106）中的至少一个。 多个询问器帧和多个应答器帧中的每个帧包括初始化序列（108和116），第一预定长度（110和118）的至少一个信息序列和第二预定长度的校验序列（ 112和120）。
