INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The field to which the present invention pertains is an antenna relating to a small portable communication device, particularly a portable communication device using a primary block and an exciter as a method of providing an antenna. [Prior Art] A small portable communication device that is an accessory for a larger portable communication device (such as a mobile phone) does communicate wirelessly with such a larger portable communication device in many cases. There are many kinds of communication technologies today, one of which is Bluetooth technology (B1Uet〇〇thTM); however, there are other technologies, such as Ultra Wide Band (UWB). If the wireless communication device is small in size, the antenna must be extremely small, as is the case with many devices that use short-range high-frequency single communication, such as devices based on the Bluetooth protocol. Examples of standard Bluetooth devices are streaming audio headsets and headsets, hands-free devices, music players, and cameras, all using μ buds to communicate with, for example, mobile phones. Therefore, usually these devices must be small in size and must be able to operate in a specific bandwidth, in which case the Bluetooth bandwidth is about 2.45 GHz or more. Most of the antennas of these small portable communication devices are placed close to the body and the human body reports that it is easy to absorb the radio energy and cause the antenna to be de-tuned. Therefore, the antennas close to the human body are mostly inferior. This is a very common problem for wireless devices like headset microphones. 122947.doc 200835052 In order to overcome this problem, the past solutions include directional antennas, such as planar inverted F antennas (7) coffee wwrted F Ant_a, and test EP i 416 as proposed another solution, basin reveals A loop antenna disposed around the four sides of the circuit board. , antenna), the energy of this antenna is guided by the human heart (4). If the small portable communication device can be attached to one of the user's body, these methods will be very feasible 'because the radiant energy will be able to diverge from the body at any time. However, these small portable communication devices may not be designed to be attached to the body - but may be attached to the body in a manner that is attached to the rope and then placed on the neck. At this time, there may be any random orientation between the small portable communication device and the body, that is, if the orientation between the small portable communication device and the antenna is incorrect, the radiant energy will be directly directed to the human body and absorbed thereby, Will lose communication with other devices you want to contact.
針對較大型可攜帶式通訊裝置之天線，US 6580397 揭示 了另一種解決方法：其敘述一種天線系統位於外殼内之行 動電話，其天線是以行動電話之屏蔽、外殼或底座之形式 作為第一天線元件並向第二天線元件饋送，而第二天線元 件位於天線之一端作為平衡體（counterpoise)，且位於行動 電話主要機身之中。 EP 1424747亦揭示了另一種天線。此文件中之天線係設 置於掀蓋式行動電話（即具有兩分離機身部份、兩者之間 122947.doc 200835052 以鉸鏈連接之行動電話類型）中。其中第—天線元件位於 第一機身部份，且佈線於其機身主要部份上；第二天線元 件以平衡體之形式位於鉸鏈位置；第三天線元件位於第^ 機身部份’且佈線於其機身主要部份上；在此，第二天: 元件亦以電連接至第一與第三天線元件。 因此對於小型且以隨機形式配掛在身上之設備來說，天 線不再應是指向型，因此出現了另—種解決方式。In the case of an antenna for a larger portable communication device, US Pat. No. 6,580,397 discloses another solution: it describes a mobile phone in which the antenna system is located in the casing, and the antenna is in the form of a shield, casing or base of the mobile phone as the first day. The line element feeds the second antenna element, and the second antenna element is located at one end of the antenna as a counterpoise and is located in the main body of the mobile phone. Another antenna is also disclosed in EP 1424747. The antenna in this document is placed in a flip-type mobile phone (that is, a type of mobile phone with two separate fuselage sections, which are hingedly connected between the two. 122947.doc 200835052). Wherein the first antenna element is located in the first body portion and is wired on the main part of the body; the second antenna element is located in the hinge position in the form of a balance body; and the third antenna element is located in the second body part And wiring on the main part of the fuselage; here, the second day: the component is also electrically connected to the first and third antenna elements. Therefore, for a small device that is attached to the body in a random form, the antenna should no longer be a pointing type, so another solution has emerged.

為解決此問題，基於本發明之立論基礎，對於且有内部 天線之小型可攜帶式通訊裝置而言，通常稱為天線之元件 僅產生出設備中一部份之輻射能，而其他影響此幅射能之 凡件為設備中其他較大型之導電元件，例如底座及裝有零 組件之電路板。這些較大型之元件（以下稱為主要區塊）將 以電容耦合及(或)電感耦合之方式耦合至這些天線元件。 因此’通常被視為天線之天線元件實際上卻是作為這些主 要區塊的激勵器。因此本發明即針對此提供一種具有此激 勵器及主要區塊組合的小型可攜帶式通訊裝置，於足夠寬 廣之頻率範圍内提供更全向性之輻射能，且即使貼近使用 者身體亦不受影響也能夠更有效率地運作。 圖2顯示一個適合裝置於圖i小型可攜帶式通訊裝置的激 勵器之透視圖。 天線激勵器元件（18)在此係由導電材料做成之導線所形 成。該導線具有第一（26)與第二（28)饋送端，用以連接至 無線電通訊設備與接地，其中第一饋送端（26)位於激勵器 (18)之輸入部份（2〇)，其呈直線且連接於繞組部份（22)之第 一圈（29)。繞組部份（22)由許多導線形成之導線圈（29， 30，32)以中心軸（36)為中心捲繞所組成，而輸入部份（2〇) 與該中心軸（3 6)平行延伸一小段距離。因此輸入部份（2〇) 實質上係連接於繞組部份（22)之右邊角度。 圖2中所示之具體實施例，導線圈（29，3〇，32)係呈螺 旋狀’因此繞組部份（22)之結構係由數個以中心軸（36)為 122947.doc -14- 200835052 中心逐漸向上捲繞之導線圈所形成。圖2中 為三，9’30’32)，然應瞭解導線圈之圈數可能會變 動。取，-圈_與前—圈或稱倒數第二圈⑽相接觸， 且距離第饋适端（26)最遠，而其他圈之間皆有_間隙之 距離。如此’卩中心轴（36)之方向來看，繞組部份之高产 1M取^於導線圈之圈數、導線之截面積及導線圈間之^ 隙。高度D1亦為繞組部份（22)之第一圈（29)與最後一圈 (30)之間的第一距離。另最後一圈（3〇)的大部份與前一圈 (32)之間亦有間隙。繞組部份（22)所有導線圈（29，3〇，^) 與中心軸（36)之距離至少為第二距離d2。如圖2之具體實 施例，由於其係一螺旋狀結構，各導線圈（29，3〇，32)與 中心轴（36)之距離皆為D2。另外，最後一圈（3〇)之末端以 約90度之角度與轉回部份（24)相連接，然後與中心軸平行 地朝第一圈（29)之方向直線經過其轉回。最後一圈（3〇)與 倒數第二圈（32)相接觸之區域或點（34)在此位於最後—圈 (30)與轉回部份（24)相連接之處。另，圖2中轉回部份（24) 係經過繞組部份（22)之内側而轉回，惟亦可選擇經由外側 轉回。轉回部份（24)除與最後一圈（30)有接觸外，其與其 他任何導線圈皆無接觸。 轉回部份（24)最後結束於饋送平面（38)上，該平面與中 心轴（36)呈垂直，且位於距離轉回部份（24)與繞組部份（22) 相連接最遠之位置。位於轉回部份（24)末端之第二饋送端 (28)，其與第一饋送端（26)同樣位於該平面（3 8)上。 如此向三維方向延展之結構’使得天線元件（18)沿中心 122947.doc -15- 200835052 軸（36)之方向於繞組部份（22)之頂端形成低阻抗端，而同 樣沿中心軸（36)之反方向於輸入部份（2〇)及轉回部份（24)形 成另一反向的低阻抗端。典型的低阻抗端在此約為5〇歐姆 (Ω)。此天線元件於繞組部份（22)沿中心軸（36)向外放射方 向亦形成一高阻抗，其中繞組部份在此係指兩個低阻抗端 之中間部份。另，第一距離D1與第二距離D2決定了此元 件（18)之實質三維元件容積。根據本發明，這些方式皆是 為了增強具有本發明中此元件（18)之天線的性能。 在此應瞭解圖2之激勵器僅為適合之激勵器的範例，亦 可考慮以其他型態與配置完成。然其仍應為三維之型態， 且最好具有兩個反向的低阻抗端而其中間具有高阻抗。 圖3係以圖形顯示依據本發明理論之小型可攜帶式通訊 裝置（14)中之天線。該裝置（14)具有一外殼（4〇)(以虛線之 圓柱狀表示）裝入所有的天線元件。該外殼（4〇)當然也可以 是其他形狀例如箱型。激勵器（18)在此位於裝置（14)的中 央’亦顯示出激勵器之中心軸（3 6)。第一主要區塊（42)與 第二主要區塊（44)沿中心轴（36)方向分別位於激勵器（18)之 相反兩侧’意即兩者（42，44)各朝向一低阻抗端，且沿中 心軸（36)方向與激勵器（18)呈一直線。各主要區塊（42，44) 與激勵器（1 8)之間皆有一間隙，而這些間隙於圖3中顯得較 大，此係為了清楚顯示出該間隙之存在而如此表示，然應 瞭解’主要區塊（42，44)與激勵器（is)之間的間隙實際上 通常要小的多，以在它們之間得到更佳的耦合效果。第一 主要區塊（42)在此以圓柱狀為例，第二主要區塊（44)以矩 122947.doc -16- 200835052 形平板狀為例，然應瞭解它們可以為任何適當的形狀，只 要是向三維方向延展即可。在示範的具體實施例中，第二 主要區塊（44)係由一電路板所構成，其具有一片位於電路 板中間的接地面（46)以及一無線電通訊設備（48)，而第一 主要區塊（42)係由電池所構成。應瞭解電路板除具有無線 電通訊設備（48)以外，仍可具有許多其他設備，然在此係 省略之以便說明本發明。 主要區塊（42，44)係由許多通常用來操作該裝置（14)之 導電零件所組成；舉例來說，這些零件可能是内部組件 (電子的、機械的、電池、印刷電路板（Printed circuit Board，PCB)等等）’但亦可使用其他像屏蔽、外殼及底座 之導電零件等零件。因此兩主要區塊之内部組件皆可以分 別使用金屬外殼覆蓋住。此外，至少其中之一的主要區塊 可能具有實質三維容積，其一部份在一垂直於中心軸（36) 之平面上朝向並覆蓋激勵器（18)之低阻抗端。並應調整主 要區塊之一或兩者之維度，使其能在期望涵蓋之頻寬中操 作。此動作通常透過適當地選擇寬度、長度及高度來完 成。若兩主要區塊皆被調整維度以在頻寬中操作，為提供 更寬之頻寬涵蓋率’更可以在不同頻率下調整兩者以得到 最佳運作效果。 激勵器（18)中第—及第二饋送端之—端連接至無線電通 訊設備（48)，另一端則連接至接地（46);二者中由哪一端 連接至哪一設備皆可。 圖3中，二主要區塊（42，4句間透過一連接裝置（50)互相 122947.doc -17- 200835052 連接在一起，而此連接裝置（50)可以是位於伸縮薄膜上之 導體，且最好為可調式，以使之可調整至高阻抗。舉例而 吕，可將連接裝置之阻抗調至約3〇〇歐姆（Ω)，如此相較於 電缆通常之阻抗50歐姆（Ω)即為高阻抗，此時將使該阻抗 为為通第連接阻抗之六倍或以上。若使用導體為連接裝 置，為使主要區塊之間互相隔離，在此可使用相當於期望 頻率波長之四分之一的長度，如此期望頻率通常即會為所 涵蓋頻覓之中心頻率。另亦可選擇透過一或多個線圈來作 為連接裝置。根據另一變化型態中，主要區塊間亦可無此 連接裝置。如此，激勵器（18)與兩主要區塊（42，44)即一 同有效地成為裝置（14)之天線。 如上述所說明有關主要區塊（42，4句與激勵器（18)之間 之定向，因主要區塊之間有低阻抗存在，將使其很容易受 到激勵器之激勵。而激勵器對於兩位置相近之主要區塊 (42，44)，主要透過繞組部份短路的最後一圈以及激勵器 (18)輸入及轉回部伤於近場區（near fieid regi〇n)進行孝馬 合，而能使整個天線達到期望之阻抗。因二主要區塊 (42，44)中至少其一與激勵器（18)兩者皆為三維結構，所 產生之天線靠近使用者身體時較不會影響其效能；另，此 結構亦可使天線涵蓋更寬之頻寬，則能夠提供一個即使於 靠近使用者身體時亦具有極佳射頻（radi〇 frequency，RF) 效能之完整的小型射頻無線裝置。由於此天線可涵蓋寬廣 之頻寬，且其輻射係全向性的，因此除藍芽標準外亦很適 合使用於超寬頻。 122947.doc -18- 200835052 圖4以圖形顯示依據本發明之第二具體實施例的一小型 可攜帶式通訊裝置（14’）。第二具體實施例與第一具體實施 例相類似，主要差異在於外殼（4〇，）内僅使用一個主要區塊 (44)來提供天線，並以一導體(52)取代第二主要區塊，該 導體朝向激勵器（18)低阻抗端並與其排列成一直線，且延 展至激勵器(18)低阻抗端之全部。導體（52)之中心點通過 激勵器(18)之中心軸(36)亦排列成一直線，如此即能有利 於導體（52)與激勵器（18)之導電（意即相接觸）。另，導電之 接觸點位於繞組部份之最後一圈。此外，亦可選擇以任何 前述第-具體實施例中之相關方式，使導體連接至主要區 塊（44)。惟應瞭解並不需要真正連接，只要「浮動式」連 接即可。 操作過程中，此導體將改善單獨主要區塊之效能，亦使 得裝置之體積更趨微小。 目5顯示根據第一具體實施例所產生天線的效率E與身體 _ 距離D之關係圖，其中效率£以分貝_為單位表示，距離 ㈣毫米（mm)為單位表示。如圖所示'，天線於靠近身體時 之效能相當好，自由空間效能亦極佳。 此天線可具有很大的頻寬，能夠涵蓋例如1.8至10.6 GHz 之頻率，其於整個頻寬下的效能亦極佳。 此天線元件亦非常簡易，可以低廉之成本製造，並可裝 置於小型可攜帶式通訊設備中。 本發月可以有許多變化之方式。根據所需頻率及頻寬， 可改變上述導線之長度、導線截面積、導線圈之圈數以及 122947.doc -19、 200835052 第一與第二距離。然而，通常導線減去最後一圈後之長 度’將隨期望涵蓋之頻寬所變化。具體實施例中之繞組部 伤呈螺叙狀（思即導線圈呈環形地圍繞著中心轴），惟亦可 為其他形狀如橢圓形及矩形。上述之主要區塊係沿中心軸 方向與激勵器叙合，然應瞭解該主要區塊之-或兩者亦可 與位於繞組部份之橫向侧邊耦合，意即以垂直於中心軸之 角度與激勵器_合。有鑑於上述與前述對於本發明之變化In order to solve this problem, based on the basis of the invention, for a small portable communication device having an internal antenna, an element generally called an antenna generates only a part of the radiant energy of the device, and the other affects the frame. The components of the energy are the other large conductive components in the device, such as the base and the circuit board with the components. These larger components (hereinafter referred to as primary blocks) will be coupled to these antenna elements in capacitive coupling and/or inductive coupling. Therefore, the antenna elements that are generally considered to be antennas actually act as exciters for these main blocks. Therefore, the present invention is directed to a small portable communication device having the combination of the exciter and the main block, which provides more omnidirectional radiant energy in a wide enough frequency range, and is not close to the user's body. Impact can also work more efficiently. Figure 2 shows a perspective view of an actuator suitable for use in the small portable communication device of Figure 1. The antenna exciter element (18) is here formed of a wire made of a conductive material. The wire has first (26) and second (28) feed ends for connection to a radio communication device and ground, wherein the first feed end (26) is located at an input portion (2〇) of the exciter (18), It is in a straight line and is connected to the first turn (29) of the winding portion (22). The winding portion (22) is composed of a plurality of wire forming guide coils (29, 30, 32) wound around the central axis (36), and the input portion (2〇) is parallel to the central axis (36) Extend a short distance. Therefore, the input portion (2〇) is substantially connected to the right angle of the winding portion (22). In the embodiment shown in Figure 2, the conducting coils (29, 3, 32) are helically shaped. Thus the winding portion (22) is constructed from a number of central axes (36) of 122947.doc -14 - 200835052 The center is formed by a winding coil that is gradually wound up. In Figure 2, three, 9'30'32), it should be understood that the number of turns of the lead coil may change. Take, -circle_ is in contact with the front-circle or the second-to-last circle (10), and is farthest from the feed-forward (26), and there is a gap between the other circles. Thus, the high-yield 1M of the winding portion is taken from the number of turns of the lead coil, the cross-sectional area of the wire, and the gap between the conductive coils. The height D1 is also the first distance between the first turn (29) of the winding portion (22) and the last turn (30). There is also a gap between the majority of the last lap (3 〇) and the previous lap (32). All of the winding coils (29, 3〇, ^) of the winding portion (22) are at least a second distance d2 from the central axis (36). As shown in the specific embodiment of Fig. 2, since each of them is a spiral structure, the distance between each of the guide coils (29, 3, 32) and the central axis (36) is D2. Further, the end of the last turn (3 turns) is connected to the turn-back portion (24) at an angle of about 90 degrees, and then linearly passes back to the first circle (29) in parallel with the central axis. The area or point (34) where the last lap (3 〇) is in contact with the penultimate lap (32) is here where the last lap (30) is connected to the reversal portion (24). In addition, the reversal portion (24) in Fig. 2 is turned back through the inner side of the winding portion (22), but may alternatively be turned back via the outer side. The return portion (24) has no contact with any other guide coil except for contact with the last lap (30). The turn-back portion (24) finally ends on the feed plane (38) which is perpendicular to the central axis (36) and is located furthest away from the turn-back portion (24) and the winding portion (22). position. A second feed end (28) at the end of the return portion (24) is located on the plane (38) as well as the first feed end (26). The structure thus extending in three dimensions causes the antenna element (18) to form a low impedance end at the top end of the winding portion (22) in the direction of the center 122947.doc -15-200835052 axis (36), and also along the central axis (36). The opposite direction of the input portion (2〇) and the return portion (24) form another inverted low impedance end. A typical low impedance end is here approximately 5 ohms (Ω). The antenna element also forms a high impedance in the outward direction of the winding portion (22) along the central axis (36), wherein the winding portion is referred to herein as the intermediate portion of the two low impedance terminals. In addition, the first distance D1 and the second distance D2 determine the substantial three-dimensional element volume of the element (18). In accordance with the present invention, these approaches are all intended to enhance the performance of an antenna having the component (18) of the present invention. It should be understood here that the exciter of Figure 2 is only an example of a suitable exciter, and may be considered in other types and configurations. It should still be in a three-dimensional form, and preferably has two inverted low impedance ends with high impedance in between. Figure 3 is a graphical representation of an antenna in a small portable communication device (14) in accordance with the teachings of the present invention. The device (14) has a housing (4 〇) (shown in a dashed line) that fits all of the antenna elements. The outer casing (4 turns) may of course also be of other shapes such as a box type. The actuator (18) is here also located at the center of the device (14) and also shows the central axis of the actuator (36). The first main block (42) and the second main block (44) are respectively located on opposite sides of the exciter (18) along the central axis (36), meaning that both (42, 44) are oriented toward a low impedance. The end is in line with the exciter (18) in the direction of the central axis (36). There is a gap between each main block (42, 44) and the exciter (18), and these gaps appear larger in Figure 3, which is so shown in order to clearly show the existence of the gap, but it should be understood The gap between the main block (42, 44) and the exciter (is) is actually much smaller in order to get a better coupling effect between them. The first main block (42) is exemplified by a cylindrical shape, and the second main block (44) is exemplified by a flat plate shape of a moment 122947.doc -16-200835052, but it should be understood that they may be any suitable shape. As long as it is extended in three dimensions. In the exemplary embodiment, the second primary block (44) is comprised of a circuit board having a ground plane (46) intermediate the circuit board and a radio communication device (48), and the first primary The block (42) is composed of a battery. It should be understood that the circuit board can have many other devices in addition to the radio communication device (48), which are omitted herein to illustrate the present invention. The main block (42, 44) consists of a number of conductive parts commonly used to operate the device (14); for example, these parts may be internal components (electronic, mechanical, battery, printed circuit board (Printed) Circuit Board, PCB), etc. 'But other parts such as shields, housings and conductive parts of the base can also be used. Therefore, the internal components of the two main blocks can be covered with a metal casing. Furthermore, at least one of the main blocks may have a substantial three-dimensional volume with a portion facing and covering the low impedance end of the exciter (18) in a plane perpendicular to the central axis (36). The dimensions of one or both of the main blocks should be adjusted to operate within the bandwidth that is expected to be covered. This action is usually done by appropriately selecting the width, length and height. If both main blocks are dimensioned to operate in the bandwidth, to provide a wider bandwidth coverage, the two can be adjusted at different frequencies for best performance. The first and second feed terminals of the exciter (18) are connected to the radio communication device (48), and the other end is connected to the ground (46); which of the two ends is connected to which device. In Figure 3, two main blocks (42, 4 sentences are connected to each other through a connecting device (50) 122947.doc -17-200835052, and the connecting device (50) may be a conductor on the stretch film, and It is preferably adjustable so that it can be adjusted to high impedance. For example, the impedance of the connecting device can be adjusted to about 3 ohms (Ω), which is 50 ohms (Ω) compared to the usual impedance of the cable. For high impedance, the impedance will be six times or more of the connection impedance. If a conductor is used as the connection device, in order to isolate the main blocks from each other, the wavelength corresponding to the desired frequency can be used. The length of one part, such that the desired frequency will usually be the center frequency of the frequency covered. Alternatively, one or more coils may be selected as the connecting means. According to another variation, the main blocks may also be There is no such connection device. Thus, the exciter (18) and the two main blocks (42, 44) are effectively together become the antenna of the device (14). As described above, the main block (42, 4 sentences and exciter) (18) orientation between the main areas The presence of a low impedance will make it very susceptible to excitation by the exciter. The exciter is for the main block (42, 44) where the two positions are close, the last turn that is mainly short-circuited through the winding part and the exciter (18). The input and the return part are injured in the near field (near fieid regi〇n) for the filial horse, so that the entire antenna can reach the desired impedance. Because at least one of the two main blocks (42, 44) and the exciter (18) Both are three-dimensional structures, and the resulting antenna is less likely to affect its performance when it is close to the user's body. In addition, the structure allows the antenna to cover a wider bandwidth, thereby providing a user closer to the user. The body also has a complete small radio frequency wireless device with excellent radio frequency (RF) performance. Because this antenna can cover a wide bandwidth and its radiation system is omnidirectional, it is also very high in addition to the Bluetooth standard. Suitable for use in ultra-wideband. 122947.doc -18- 200835052 Figure 4 graphically shows a small portable communication device (14') in accordance with a second embodiment of the present invention. Second embodiment and first implementation Case Similarly, the main difference is that only one main block (44) is used in the outer casing (4〇) to provide the antenna, and the second main block is replaced by a conductor (52) facing the low impedance end of the exciter (18). And arranged in a straight line, and extended to the low impedance end of the exciter (18). The center point of the conductor (52) is also arranged in a straight line through the central axis (36) of the exciter (18), thus facilitating the conductor (52) conductive (ie, in contact with the exciter (18). In addition, the conductive contact point is located at the last turn of the winding portion. Alternatively, it may be selected in any of the foregoing-specific embodiments. , connecting the conductor to the main block (44). However, you should understand that you don't need a real connection, just a "floating" connection. During operation, this conductor will improve the performance of the individual main blocks and make the device smaller. Item 5 shows a graph of the efficiency E of the antenna generated according to the first embodiment and the body_distance D, wherein the efficiency is expressed in units of decibels, expressed in units of distance (four) millimeters (mm). As shown in the figure, the antenna is quite effective when it is close to the body, and the free space performance is also excellent. This antenna can have a large bandwidth and can cover frequencies such as 1.8 to 10.6 GHz, which is also excellent in overall bandwidth. The antenna element is also very simple, can be manufactured at low cost, and can be installed in a small portable communication device. There are many ways to change this month. Depending on the desired frequency and bandwidth, the length of the wire, the cross-sectional area of the wire, the number of turns of the conductive coil, and the first and second distances of 122947.doc -19, 200835052 can be changed. However, usually the length of the wire after subtracting the last lap will vary depending on the bandwidth desired to be covered. In the embodiment, the winding portion is spirally shaped (the coil is circularly surrounding the central axis), but may be other shapes such as an ellipse and a rectangle. The main block described above is merged with the exciter along the central axis direction. However, it should be understood that the main block or both may be coupled to the lateral sides of the winding portion, that is, at an angle perpendicular to the central axis. Combined with the exciter. In view of the above and the foregoing changes to the present invention
