組合可在傳送信號320上產生一信號，其模仿由上文參看 圖12之傳送斋來論述的傳送調變信號224產生的傳送調 變〇 本迤明之例示性貫施例包括對接收器件之電流及取的調 變及對接收天線之阻抗的調變以實現反向鏈路發信號。參 看圖13 A及圖12兩者，在接收器件之電力汲取變化時，負 載感測電路216偵測傳送天線上之所得電力變化，且由此 等變化可產生接收信號235。 在圖13A至圖13C之實施例中，可藉由修改開關S1A及 S2A之狀態來改變經由傳送器之電流汲取。在圖l3A中， 140360.doc •20· 201001869 開關S1A及開關S2A均斷開而產生一「DC斷開狀態」且實 質上自傳送天線204移除負載。此減少傳送器所看到之電 流。 在圖13B中，開關S1A閉合且開關S2A斷開，從而產生接 收天線304之「DC短路狀態」。因此，可使用圖ub中之狀 態來增加在傳送器中所看到之電流。 在圖13C中，開關S1A斷開且開關S2A閉合而產生一正常 接收模式（在本文中亦被稱作「DC操作狀態」），其中電力 可由DC輸出信號322供應且可偵測到傳送信號32〇。在圖 13C所不之狀態下，接收器接收一正常電力量，因此消耗 比DC斷開狀態或DC短路狀態時多或少的來自傳送天線之 電力。 反向鏈路發信號可藉由DC操作狀態（圖13C)與DC短路狀 態（圖13B)之間的切換來實現。反向鏈路發信號亦可藉由 DC操作狀態（圖13C)與dc斷開狀態（圖13A)之間的切換來 實現。 圖14A至圖14C展示在各種狀態下之替代接收電路的一 部分的簡圖以說明接收器與傳送器之間的訊息傳遞。 圖14A至圖14C皆展示相同電路元件，+同之處為各個 開關之狀態。接收天線3〇4包括一特性電扣，特性電感 L1驅動節點350。節點mo經由電容器及開關仙來選擇

整流器318連接至開關S2B，開關S2B串聯連接於電阻器 R2及接地端。整流器318亦連接至開關S3；^開關S3B之另 一側將D C電力信號3 2 2供應至一接收器件（未圖示）以對該 接收器件供電、對電池充電，或其組合。 在圖13A至圖l3C中，藉由經由開關S1B選擇性地將接收 天線304耦合至接地端來改變該接收天線之Dc阻抗。相對 照地，在圖！4A至圖14C之實施例中，可藉由修改開關 SIB、S2B及S3B之狀態以改變接收天線3〇42AC阻抗來修 改天線之阻抗以產生反向鏈路發信號。在圖14A至圖 中，可藉由電容器C2來調諧接收天線3〇4之諧振頻率。因 此，可藉由使用開關S1B經由電容器C1來選擇性地耦合接 收天線304(基本上將諧振電路改變至將在與傳送天線最佳 耦合的範圍外的不同頻率）來改變接收天線^々的八匚阻抗。 若接收天線304之諧振頻率接近於傳送天線之諧振頻率， 且接收天線304處於傳送天線之近場中，則可形成一耦合 模式’其中接收器可自輕射場1 〇6汲取顯著電力。 在圓14A中，開關S1B閉合，此將天線去諧且產生一 「AC覆蓋狀態」，該「Ac覆蓋狀態」基本上「覆蓋」接收 天線304使之免於被傳送天線2〇4偵測到，因為接收天線不 在傳送天線之頻率處諧振。由於接收天線將不處於耦合模 式下，所以開關S2B及S3B之狀態對於本論述而言並非特 140360.doc -22- 201001869 別重要。 在圖14Β中，開關S1B斷開，開關S2B閉合，且開關㈣ 斷開，從而產生接收天線304之「經調諧假負載狀態」。因 為開關S輯開，所以電容器〇不影響譜振電路，且與電 容器C2組合之接收天線304將處於可與傳送天線之譜振頻 率匹配的一譜振頻率下。開關S3B斷開與開關S2B閉合之 組合為整流器產生一相對高電流假負載，其將經由接收天 f κ 線304沒取更多電力，此可由傳送天線感測到。另外，可 债測到傳送信號320，因為接收天線處於自傳送天線接收 電力的狀態下。 在圖14C中，開關S1B斷開，開關S2B斷開，且開關㈣ 閉合，從而產生接收天線3〇4之「經調諧操作狀態」。因為 開關s1B斷開，所以電容器C1不影㈣振電路，且與電容 HC2組合之接收天線3〇4將處於可與傳送天線之諧振頻率 匹配的-諧振頻率下。開關S2B斷開與開關_閉合之組

期間接收器應不執行反向鏈路發信號。此外，若兩個接收 益件試圖同時執行反向鏈路發信號，則衝突可發生，此將 使傳送器難以（若非不可能）解碼適當反向鏈路信號。 在本文所描述之例示性實施例中，發信號類似於具有 140360.doc •24- 201001869 開始位元、-資料位元組、一同位位元及一停止位元的通 用非同步接收傳送（UART)串列通信協定。當然：，任何串

該耦合模式區中時，傳送器將保持在低電力狀態下（如圖 15A所說明）且在每個循環週期41〇重複同步脈衝42〇。同步 脈衝420在前向鏈路週期424期間將包括—NDq，且傳送器 在監聽週期426期間將監聽答覆。若未接收到答覆，則傳 送器停機，直至用於下一個循環週期41〇之同步脈衝42〇的 時間為止。 在將新接收器件引入至該耦合模式區時，該接收器件最 初開啟且監聽一同步脈衝420。該新接收器件可將同步脈
