The ECU includes a CPU and an interface that receives a signal from a detection unit that outputs a signal indicating whether the charging connector is connected to the inlet and whether the charging connector is for DC or AC. The CPU uses the signal received by the interface to determine whether the charging connector connected to the inlet is for AC / DC (S112), and after it is determined whether the charging connector is for AC / DC, the CPU unlocks a lock device according to different conditions depending on whether the charging connector is determined to be for AC or DC (S116-8).

Description

[Technical field]

[0001] The present disclosure relates to a control device for a locking device, and more particularly to a control device for a locking device that fixes a charging connector of a power supply device to an inlet of a vehicle. [Background technology]

[0002] Conventionally, there has been a technique for appropriately controlling a locking mechanism according to the type of charging connector attached to a vehicle inlet (see, for example, Patent Document 1). In this technique, an ECU acquires a pilot signal CPLT and a connector connection signal PISW, and determines the type of charging connector when the charging connector is attached. If the ECU has a function corresponding to the type of the attached charging connector, the ECU controls the charging connector to a locked state and executes control corresponding to the attached charging connector. If the ECU does not have a function corresponding to the type of the attached charging connector, the ECU maintains the unlocked state of the charging connector.

[0003] [Patent Document 1] JP 2023-59944 A Summary of the Invention [Problem to be solved by the invention]

[0004] Fig. 5 is a timing chart relating to conventional connector connection. With reference to Fig. 5, in the technology of Patent Document 1, when the charging connector is connected, the charging connector is controlled to a locked state, and then the type of the charging connector is identified by a pilot signal CPLT. In the case of AC charging, when an unlocking operation is performed, the charging connector is controlled to an unlocked state, and in the case of DC charging, the charging connector is not controlled to an unlocked state even if an unlocking operation is performed. However, until identification of the type of the charging connector is completed, regardless of whether or not charging is AC, there is a possibility that the charging connector cannot be set to an unlocked state.

[0005] This disclosure has been made to solve the above-mentioned problems, and its purpose is to provide a control device for a locking device that is capable of unlocking the locking device of a charging connector even when determination of the type of charging connector has not been completed. [Means for solving the problem]

[0006] The control device of a locking device according to the present disclosure is a control device of a locking device that fixes a charging connector of a power supply device to an inlet of a vehicle. The control device includes a processor and a receiving unit that receives a signal from a detection unit that outputs a signal indicating whether the charging connector is connected to the inlet and whether the charging connector is for DC or AC. The processor determines whether the charging connector connected to the inlet is for AC or DC using the signal received by the receiving unit, and after it is determined that the charging connector is for AC or DC, the processor sets the locking device to an unlocked state according to a condition that differs depending on whether it is determined to be for AC or DC, whereas before it is determined that the charging connector is for AC or DC, the processor sets the locking device to an unlocked state according to the condition for AC.

[0007] According to this configuration, it is possible to provide a control device for a locking device that can set the locking device of the charging connector to an unlocked state even when determination of the type of the charging connector has not been completed.

[0008] When it is determined that the charging connector is for DC, if the charging connector is in an unlocked state, the processor may set the lock device to a locked state.

[0009] Conventional DC charging connectors are locked when connection confirmation is performed. The locked state is maintained until charging is started. However, according to the above-described configuration, even if the charging connector is a DC charging connector, it may be unlocked after connection confirmation. According to such a configuration, when the charging connector is determined to be for DC use, the charging connector is again locked. As a result, charging can be started after the charging connector is locked.

[0010] The processor may be configured to place the locking device in a locked state in response to an operation for placing the locking device in a locked state when it is determined that the charging connector is for AC power.

[0011] According to this configuration, when the charging connector is an AC connector, the locking device can be set to the locked state in response to an operation to set the charging connector to the locked state. Effect of the Invention

[0012] According to this disclosure, it is possible to provide a control device for a locking device that is capable of setting the locking device of a charging connector to an unlocked state even when determination of the type of the charging connector has not been completed.

[0014] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and their description will not be repeated.

[0015] The configuration of an electric vehicle (hereinafter, referred to as vehicle) 200 according to this embodiment will be described below. Fig. 1 is a diagram showing an example of the configuration of vehicle 200. Vehicle 200 includes electric vehicles capable of receiving and transmitting electric power to and from electric devices external to vehicle 200, such as plug-in hybrid vehicles and electric vehicles. In Fig. 1, for example, it is assumed that vehicle 200 is parked in a parking space in which power supply equipment 10 is installed.

[0016] As shown in FIG. 1, a vehicle 200 includes an ECU (Electronic Control Unit) 100, an inlet 202, a power conversion device 204, a locking mechanism 206, a battery 214, an inverter 216, and a motor generator (MG) 218.

[0017] The motor generator 218 is, for example, a three-phase AC rotating electric machine, and has a function as an electric motor (motor) and a function as a generator. That is, the motor generator 218 exchanges electric power with the inverter 216.

[0018] For example, when driving the vehicle 200, the motor generator 218 applies a rotational force to the drive wheels 222 using the electric power supplied from the inverter 216. The drive wheels 222 rotate by the rotational force applied by the motor generator 218, and drive the vehicle 200. Note that the number of motor generators 218 is not limited to one, and a configuration in which a plurality of motor generators 218 are provided may be adopted.

[0019] The inverter 216 converts power bidirectionally between the motor generator 218 and the battery 214 in response to a control signal from the ECU 100. For example, when the motor generator 218 is driven, the inverter 216 converts DC power of the battery 214 into AC power and supplies it to the motor generator 218. Furthermore, for example, when the motor generator 218 is generating power, the inverter 216 converts AC power (regenerative power) generated in the motor generator 218 into DC power and supplies it to the battery 214. Note that a converter that adjusts the voltage of the inverter 216 and the voltage of the battery 214 may be provided between the inverter 216 and the battery 214.

[0020] The battery 214 is, for example, a rechargeable power storage element, and is typically a secondary battery such as a nickel-metal hydride battery or a lithium-ion battery having a solid or liquid electrolyte. Alternatively, the battery 214 may be any power storage device capable of storing power, and for example, a large-capacity capacitor may be used instead of the battery 214.

[0021] The battery 214 is externally charged using power supplied from the power supply facility 10. External charging includes AC charging using DC power supplied by converting AC power supplied from the external facility (power supply facility 10) to the inlet 202 in the power conversion device 204, and DC charging using DC power supplied from the power supply facility 10 to the inlet 202 without passing through the power conversion device 204.

[0022] The inlet 202 is provided on the exterior of the vehicle 200 together with a cover such as a lid (not shown), and is configured to allow various connectors, which will be described later, to be attached thereto. The inlet 202 can receive a supply of electric power used to charge the battery 214 from an external facility.

[0023] Inlet 202 has a shape that allows it to be attached to either charging connector 17 used for AC charging or charging connector 18 used for DC charging. Inlet 202 is provided with AC connection portions 202a and 202b, DC connection portions 202f and 202g, and communication portions 202c to 202e.

[0024] When AC charging connector 17 of power supply equipment 10 is attached to inlet 202, the AC connection portion (see FIG. 2) of AC charging connector 17 is electrically connected to AC connection portions 202a, 202b of inlet 202, and the communication portion (see FIG. 2) of AC charging connector 17 is connected to communication portions 202c to 202e of inlet 202.

[0025] When the DC charging connector 18 of the power supply equipment 10 is attached to the inlet 202, an AC connection portion (not shown) of the DC charging connector 18 is electrically connected to the AC connection portions 202a, 202b of the inlet 202, and a communication portion (not shown) of the DC charging connector 18 is connected to communication portions 202c to 202e of the inlet 202.

[0026] Power conversion device 204 performs power conversion between battery 214 and inlet 202 in response to a control signal from ECU 100. For example, when AC charging is performed on battery 214 with AC charging connector 17 attached to inlet 202, power conversion device 204 converts AC power supplied from AC charging connector 17 into DC power and charges battery 214 with the converted DC power.

[0027] Lock mechanism 206 restricts removal of the connector attached to inlet 202 to set the connector to a state (locked state) fixed to inlet 202, or releases the restriction on removal of the connector to set the connector to a state (unlocked state) allowing removal of the connector from inlet 202. Lock mechanism 206 is provided with an actuator that, for example, moves a member to a position that restricts movement of the connector attached to inlet 202 to set the locked state, or moves the member to a position that allows movement of the connector attached to inlet 202 to set the unlocked state. That is, lock mechanism 206 switches from one of the locked state and the unlocked state to the other state in response to a control signal from ECU 100.

[0028] ECU 100 incorporates a CPU (Central Processing Unit) 101, a memory (including, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), etc.) 102, and an interface 103, and outputs signals from interface 103 so that vehicle 200 is in a desired state based on information such as maps and programs stored in memory 102 and information received by interface 103 from various sensors, thereby controlling various devices (for example, power conversion device 204, lock mechanism 206, or inverter 216). Note that the various controls performed by ECU 100 are not limited to processing by software, and it is also possible to configure dedicated hardware (electronic circuits) and perform the processing.

[0029] Furthermore, when a connector (AC charging connector 17, DC charging connector 18) is attached to inlet 202, ECU 100 executes a communication process to receive predetermined information from a device on the connector side (power supply equipment 10) via interface 103. The predetermined information includes, for example, information about power that can be exchanged between power supply equipment 10 and battery 214 (such as a connector connection signal PISW, which will be described later).

[0030] For example, when AC charging connector 17 is attached to inlet 202, ECU 100 receives predetermined information via interface 103 from power supply equipment 10 (more specifically, AC charging connector 17) including information indicating that the communication unit of AC charging connector 17 is connected to communication units 202c, 202d, and 202e of inlet 202, and information indicating that the power exchanged between the attached AC charging connector 17 and inlet 202 is AC power, and information indicating that the power exchanged between AC charging connector 17 and inlet 202 is charging power for charging battery 214.

[0031] Alternatively, for example, when a DC charging connector 18 is attached to inlet 202, ECU 100 connects the communication unit of the DC charging connector 18 to communication units 202c, 202d, and 202f of inlet 202, and receives predetermined information from power supply equipment 10 (more specifically, DC charging connector 18) via interface 103, the information including information indicating that the power exchanged between the DC charging connector 18 attached from power supply equipment 10 and inlet 202 is direct current power, and information indicating that the power exchanged between the DC charging connector 18 and inlet 202 is charging power.

[0032] When AC charging connector 17 of power supply equipment 10 is attached to inlet 202 of vehicle 200, power supply equipment 10 supplies AC power to inlet 202. The AC power supplied to inlet 202 is converted to DC power by power conversion device 204. The converted DC power is supplied to battery 214, and battery 214 is charged.

[0033] When the DC charging connector 18 of the power supply equipment 10 is attached to the inlet 202 of the vehicle 200, the power supply equipment 10 supplies DC power to the inlet 202. The DC power supplied to the inlet 202 is supplied to the battery 214 without passing through the power conversion device 204, and the battery 214 is charged.

[0034] 2, a circuit configuration in power supply equipment 10 and vehicle 200 will be described using an example in which an AC charging connector 17 is attached to inlet 202. Fig. 2 is a diagram showing an example of a circuit configuration in power supply equipment 10 and vehicle 200.

[0035] The power supply equipment 10 includes power supply relays K1 and K2, a power supply control device 10a, and an oscillator circuit 10b. When the power supply relays K1 and K2 are in an open state, the power supply path is interrupted. When the power supply relays K1 and K2 are in a closed state, power can be supplied from the AC power source of the power supply equipment 10 to the vehicle 200 via the AC charging connector 17 and the inlet 202.

[0036] The oscillator circuit 10b outputs a pilot signal CPLT to the ECU 100 via the AC charging connector 17 and the inlet 202. The potential of the pilot signal CPLT is manipulated by the ECU 100, and the pilot signal CPLT is used as a signal for remotely operating the power supply relays K1 and K2 from the ECU 100.

[0037] The power supply control device 10a controls the power supply relays K1 and K2 based on the potential of the pilot signal CPLT. The pilot signal CPLT is also used as a signal for notifying the ECU 100 of the rated current during AC charging from the oscillator circuit 10b.

[0038] The power supply control device 10a includes a CPU, a memory, etc. The power supply control device 10a detects the potential of a pilot signal CPLT output by the oscillation circuit 10b, and controls the operation of the oscillation circuit 10b based on the detected potential of the pilot signal CPLT.

[0039] When no connector is connected to the inlet 202, the power supply control device 10a controls the operation of the oscillation circuit 10b so that the battery is at V0 (for example, +12 V) and a non-oscillating pilot signal CPLT is output.

[0040] Specifically, the oscillation circuit 10b includes, for example, a switch S1 and a resistor R1. One end of the resistor R1 is connected to the switch S1. The other end of the resistor R1 is connected to one end of a signal line L1. The other end of the signal line L1 is electrically connected to the communication unit 202e when the AC charging connector 17 is attached to the inlet 202. The switch S1 is configured to connect the resistor R1 to either one of the +12V power supply of the power supply control device 10a and the oscillation device of the power supply control device 10a. When no connector is connected to the inlet 202, the power supply control device 10a controls the switch S1 so that the +12V power supply and the resistor R1 are in a conductive state. Therefore, the oscillation circuit 10b outputs a pilot signal CPLT having a potential of +12V and not oscillating to the signal line L1.

[0041] When a connector is connected to the inlet 202, the power supply control device 10a controls the operation of the oscillation circuit 10b so that a pilot signal CPLT that oscillates at a specified frequency and duty cycle is output.

[0042] Specifically, for example, when the AC charging connector 17 is connected, the resistor R1 and a resistor R3 (described later) on the vehicle 200 side are brought into a conductive state, and the potential of the pilot signal CPLT drops to V1, which is lower than V0. Therefore, the power supply control device 10a controls the switch S1 so that the oscillator device and the resistor R1 are brought into a conductive state. Therefore, the oscillator circuit 10b outputs to the signal line L1 a pilot signal CPLT whose upper limit value of potential is V1 and which oscillates at a specified frequency and duty cycle.

[0043] The duty cycle of the pilot signal CPLT is preset according to the rated current. The ECU 100 can obtain the rated current of the power supply equipment 10 by using the duty cycle of the pilot signal CPLT received by the interface 103 via the communication unit 202e.

[0044] When the upper limit value of the potential of the pilot signal CPLT drops to V2 (<V1), the power supply control device 10a controls the power supply relays K1 and K2 to be in a closed state. As a result, power from the AC power supply is supplied to the inlet 202 via the AC charging connector 17. The upper limit value of the potential of the pilot signal CPLT drops to V2, for example, when a switch S2 (described later) becomes conductive.

[0045] The AC charging connector 17 includes resistors R4, RC, and a switch S3. One end of the switch S3 is connected to the ground wire L3. The other end of the switch S3 is connected to one end of the resistor RC. The resistor R4 is connected in parallel with the switch S3. The other end of the resistor RC is connected to the signal line L2. The signal line L2 is electrically connected to the communication unit 202d when the AC charging connector 17 is attached to the inlet 202.

[0046] The switch S3 is interlocked with a push button provided on the AC charging connector 17. When the push button is not pressed, the switch S3 is in a closed state. When the push button is pressed, the switch S3 is in an open state.

[0047] One end of a resistor R5 is connected to the communication unit 202d, and the other end of the resistor R5 is connected to the power supply Vsmp. The ECU 100 is configured to be able to acquire the potential between the resistor R5 and the communication unit 202d. A connection detection circuit for detecting the connection state between the AC charging connector 17 and the inlet 202 is constituted by the resistors RC, R4, R5, the switch S3, and the power supply Vsmp.

[0048] When the AC charging connector 17 is attached to the inlet 202, a signal of a potential (V3) determined by the voltage of the power supply Vsmp and the resistance value of the resistor R5 is generated on the signal line L2 as the connector connection signal PISW.

[0049] When an AC charging connector 17 is attached to the inlet 202 and the push button is not operated, a signal of a potential (V4) determined by the voltage of the power supply Vsmp and resistors R5 and RC is generated on the signal line L2 as a connector connection signal PISW.

[0050] When the push button is operated with the AC charging connector 17 attached to the inlet 202, a signal of a potential (V5) determined by the voltage of the power supply Vsmp and resistors R4, R5, and RC is generated on the signal line L2 as the connector connection signal PISW.

[0051] Therefore, by acquiring the potential of the connector connection signal PISW, ECU 100 can detect the connection state between AC charging connector 17 and inlet 202. Furthermore, at least resistance RC is different between AC charging connector 17 and DC charging connector 18. Therefore, ECU 100 can acquire the type of the connected connector from the potential of connector connection signal PISW when the connector is connected to inlet 202.

[0052] The vehicle 200 further includes a resistance circuit 110. The resistance circuit 110 is a circuit for manipulating the potential of the pilot signal CPLT generated in the signal line L1. The resistance circuit 110 includes resistors R2 and R3 and a switch S2.

[0053] One end of the resistor R2 is connected to the ground line L3 via the switch S2. The other end of the resistor R2 is connected to the signal line L1 from which the pilot signal CPLT is generated. The resistor R3 is connected between the signal line L1 and the ground line L3. That is, one end of the resistor R3 is connected to the ground line L3. The other end of the resistor R3 is connected to the signal line L1. The switch S2 is turned on / off in response to a control signal from the ECU 100.

[0054] When the AC charging connector 17 is attached to the inlet 202 and the switch S2 is in the off state (disconnected state), the potential of the pilot signal CPLT becomes a potential V1 determined by the resistors R1 and R3. When the AC charging connector 17 is attached to the inlet 202 and the switch S2 is in the on state (conducting state), the potential of the pilot signal CPLT becomes a potential V2 determined by the resistors R1, R2, and R3.

[0055] When an AC charging connector 17 is attached to inlet 202, ECU 100 switches switch S2 on / off to change the potential of pilot signal CPLT, thereby requesting power feeding equipment 10 to start and stop power feeding.

[0056] Specifically, the ECU 100 requests the power supply equipment 10 to supply power, for example, by turning on the switch S2 and changing the potential of the pilot signal CPLT from V1 to V2. Also, the ECU 100 requests the power supply equipment 10 to stop supplying power, for example, by turning off the switch S2 and changing the potential of the pilot signal CPLT from V2 to V1.

[0057] When the switch S2 is turned on and the power supply relays K1, K2 are closed by the power supply control device 10a, AC power is supplied from the power supply equipment 10 to the power conversion device 204 via the inlet 202. After completing a predetermined charging preparation process, the ECU 100 operates the power conversion device 204 to convert the AC power into DC power and charge the battery 214.

[0058] Conventionally, as described above, the charging connector is controlled to the locked state when AC charging connector 17 or DC charging connector 18 is connected, and then the type of charging connector is identified by pilot signal CPLT. In the case of AC charging, charging connector 17 is controlled to the unlocked state when an unlocking operation is performed, and in the case of DC charging, charging connector 18 is not controlled to the unlocked state even if an unlocking operation is performed. However, until identification of the type of charging connector is completed, regardless of whether charging is AC or not, there is a possibility that the charging connector cannot be put into the unlocked state.

[0059] Therefore, ECU 100 determines whether the charging connector connected to the inlet is for AC or DC using the signal received by the receiving unit, and after it has been determined that the charging connector is for AC or DC, ECU 100 sets locking mechanism 206 to an unlocked state according to conditions that differ depending on whether the charging connector is determined to be for AC or DC, whereas before it is determined that the charging connector is for AC or DC, ECU 100 sets locking mechanism 206 to an unlocked state according to the conditions for AC.

[0060] This allows lock mechanism 206 of the charging connector to be placed in an unlocked state even if the determination of the type of the charging connector has not been completed.

[0061] 3 is a flowchart showing the flow of the release condition allocation process, which is executed by CPU 101 of ECU 100 at predetermined intervals from a higher-level process.

[0062] CPU 101 determines whether or not a charging connector is connected to inlet 202 (step S111). If it determines that the charging connector is not connected (NO in step S111), CPU 101 returns the process to be executed to a higher-level process. On the other hand, if it determines that the charging connector is connected (YES in step S111), CPU 101 determines whether or not the determination of whether the charging connector is for AC or DC has been completed (step S112).

[0063] When it is determined that the AC / DC determination is not completed (NO in step S112), the CPU 101 determines whether communication with the power supply equipment 10 is performed by HLC (High Level Communication) communication (step S113). HLC communication is communication compatible with ISO15118, and is digital communication for bidirectional information exchange between the vehicle 200 and the power supply equipment 10. The HLC communication signal is superimposed on the pilot signal CPLT and transmitted and received between the ECU 100 and the power supply control device 10a.

[0064] In HLC communication, the determination of AC / DC may take time due to some factor. If it is determined that HLC communication is being performed (YES in step S113), CPU 101 sets the release condition for unlocking lock mechanism 206 to the release condition for AC, regardless of DC charging or AC charging (step S114). On the other hand, if it is determined that HLC communication is not being performed (NO in step S113) or after step S114, CPU 101 returns the processing to be executed to the upper level processing. In this case, since it is not HLC communication, the determination of AC / DC is immediately completed, and it is determined that the determination of AC / DC is completed in step S112 of the following execution cycle.

[0065] When it is determined that the AC / DC determination is complete (YES in step S112), CPU 101 determines whether or not AC charging has been determined (step S116). When it is determined that AC charging has been determined (YES in step S116), CPU 101 sets the release condition to the release condition for AC (step S117). On the other hand, when it is determined that charging is not AC charging, that is, charging is determined to be DC charging (NO in step S116), CPU 101 sets the release condition to the release condition for DC (step S118). After step S117 or step S118, CPU 101 returns the process to be executed to the upper process.

[0066] Fig. 4 is a timing chart relating to connector connection in the case of HLC communication. Referring to Fig. 4, until the determination for AC / DC is completed, the charging connector is unlocked in accordance with the release condition for AC (for example, a condition that a door unlock operation has been performed) regardless of whether charging is AC or DC. After the determination for AC / DC is completed, in the case of AC charging, charging connector 17 for AC is locked in response to a lock operation (door lock operation in the figure) and is unlocked in accordance with the release condition for AC, whereas in the case of DC charging, charging connector 18 for DC is locked when the determination is completed and then unlocked in accordance with the release condition for DC (for example, a condition that charging has been stopped).

[0067] [Variations] (1) In the embodiment described above, in step S113 in Fig. 3, it is determined whether communication with power supply equipment 10 is performed by HLC communication. However, the present invention is not limited to HLC communication, and any other communication method may be used as long as it takes a longer time to determine whether the charging connector is for AC or DC compared to pilot signal CPLT.

[0068] (2) In the embodiment described above, the type of connector is a Combined Charging System (CCS), as shown in the diagram of inlet 202 in Fig. 1. However, the type of connector is not limited to this, and may be any other type as long as it is a type that combines AC and DC.

[0069] (3) The above disclosure can be considered as disclosure of a control device such as vehicle 200 or ECU 100, or a control method or control program executed by these.

[0070] [summary] (1) As shown in Figures 1 to 3, ECU 100 is a control device for locking mechanism 206 that fixes charging connectors 17, 18 of power supply equipment 10 to inlet 202 of vehicle 200. As shown in Figures 1 and 2, ECU 100 includes a CPU 101 and an interface 103 that receives a signal from a detection unit (the circuit shown in Figure 2) that outputs a signal indicating whether charging connectors 17, 18 are connected to inlet 202 and whether the charging connector is for DC or AC. As shown in Figures 3 and 4, CPU 101 determines whether the charging connector connected to inlet 202 is for AC or DC using a signal received by interface 103 (for example, step S112), and after it has been determined that the charging connector is for AC or DC, it unlocks the locking device according to different conditions depending on whether it has been determined that the charging connector is for AC or DC (for example, steps S116 to S118). On the other hand, before it is determined that the charging connector is for AC or DC, it unlocks the locking device according to the conditions for AC (for example, steps S113 and S114).

[0071] This allows lock mechanism 206 of the charging connector to be placed in an unlocked state even if the determination of the type of the charging connector has not been completed.

[0072] (2) As shown in FIG. 4, when charging connector 18 is determined to be for DC use and charging connector 18 is in an unlocked state, CPU 101 may set the lock device to a locked state.

[0073] Thus, when the charging connector is determined to be for DC use, the charging connector is again placed in the locked state, so that charging can be started after the charging connector is placed in the locked state.

[0074] (3) As shown in FIG. 4, when it is determined that the charging connector is for AC, CPU 101 may set lock mechanism 206 to the locked state in response to an operation for setting lock mechanism 206 to the locked state.

[0075] As a result, when the charging connector is for AC use, the locking mechanism 206 can be set to the locked state in response to an operation to set the charging connector to the locked state.

[0076] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the disclosure is defined by the claims, not by the description of the embodiments described above, and is intended to include all modifications within the meaning and scope of the claims.
