As shown, the remote control device 10 includes a face cover panel 18 provided with an opening 22, which is generally rectangular for inserting a push button 25, and a generally rectangular shape for inserting the push button 25. Base panel with multiple pushbutton openings 24 that are rectangular
14 upper housing members 12 are provided,
Push button 25 protruding from its upper surface 34
A body panel 26 made of a flexible material, having a conductive switch 38 on an upper surface 40 thereof, and a printed circuit board 36 having an operation circuit 42 (FIG. 7) mounted on the back side thereof, and a lower housing member 16 And a cover 44 of a battery compartment 45 (FIG. 7) for accommodating a battery 46 (FIG. 10) for the operation circuit 42 of the remote control device 10, and an infrared transmitting lens 31.

Base panel 14 of upper housing member 12 is horizontal 14
Note the complete alignment of the row and four row of pushbutton openings 24. However, not all of these openings (holes) 24 accept pushbuttons 25. This will be apparent due to the smaller number of pushbutton openings 22 provided on the face cover panel 18. Similarly, the body panel 26 is initially sized 14 across the upper surface 34.
It has a row, four rows of fully arranged pushbuttons 25.

Although the printed circuit board 36 may be provided with more conductive switches 38 than the illustrated remote controller 10 or necessary, the conductive switches aligned with each push button 25. Has 38. The provision of the auxiliary push button opening 24 in the base panel 14 allows the remote control device 10 to be improved by adding the auxiliary push button 25 to perform a number of other functions on demand. .

This mechanism of upper housing member 12 and lower housing member 16, panels 14 and 18, and circuit board 36 provide the desired additional functionality.
It is possible to improve the remote control device 10 by including an additional circuit in the operation circuit 42 and adding the push button 25. In this regard, face cover panel 18
Is easy to remove to improve the remote control device 10 by adjusting the number of push buttons 25 and their associated switches 38.

The structural simplicity of push button 25, base panel 14 and face cover panel 18 is illustrated in FIGS. As shown in FIG. 3, the body panel 26 has a plurality of raised push buttons 25. Each square button 25 has a recess (space) 48 on the underside 49 of each button 25 and is internally adapted to engage one of the conductive switches 38 on the circuit board 36. It is equipped with (puck) 50. As shown in FIG. 4, the push button 25 made of a flexible material and the panel 26 make it easy to cut out the unnecessary button 25 with scissors or other cutting device.

As shown in FIG. 6, when the body panel 26 and the base panel portion 14 are combined, the face cover panel
18 is mounted on the tip of the base panel 14, and the circuit board 36 is mounted in the housing member 12.

FIG. 7 shows an operation circuit 42 of the remote control device 10 including a battery 46 (FIG. 10) mounted in a compartment 45 for supplying power to the circuit 42 and a lithium battery 52 for backing up a static RAM 54.
It is shown. The central processing unit (CPU) 56 is coupled to the RAM 54 via a latch 58. Three LEDs, LED1, LED2 and LED
3 is a circuit 42 for communicating information with the controlled device
Is coupled with. All elements of circuit 42 are mounted on circuit board 36, which is mounted within upper housing member 12. Further, the LED 4 is coupled to the CPU 56 for transmitting information to the user of the remote control device 10, as will be described in detail below.

A schematic block circuit diagram of the operation circuit 42 is shown in FIG. 8, which includes a CPU 56 and an infrared light emitting diode C.
LED1, LED2 and LED3 coupled with PU56,
CPU56 serial input / output port 60 and CPU
It includes a RAM 54 coupled to 56 and backed up by a lithium battery 52, and a keyboard 61 with 4 × 14 keys coupled to a CPU 56. Four AAA batteries 46 are also shown therein.

9A and 9B are detailed circuit diagrams of the operation circuit 42. The operation circuit 42 includes a central process unit 56, a latch 58, a RAM 54, LED1, LED2, LED3 and L.
Includes ED4 and.

The operation circuit 42 further includes several sub-circuits 62. One of these subcircuits 62 (FIG. 9B) includes a keyboard 61 having pushbuttons 25 each connected to a CPU 63 shown in FIG. 9B,
This will be referred to as a keyboard circuit 62. Figure
The X mark shown in 9B indicates each push button 25, and when one of these push buttons X is pressed, the current flows through the register in one column. For example, when button 25 'is pressed, current will flow through register 64 in column 138 leading to button (key) 25'. By this operation, the voltage of the supply line VCC supplied to the CPU 56 of the microprocessor rises.

Thus, as will be described below, the wake-up circuit is used to "wake up" the CPU 56 whenever the button 25 is pressed, ie to provide energy to the CPU 56.
It will increase the voltage on the VCC line which serves to initiate the switch-on process at 70.

Keyboard circuit 62 and wake-up circuit
In addition to 70, the subcircuit includes a reset circuit 74 and a write protect circuit 78.

When the voltage on the VCC line rises, the signal goes to capacitor 1
It passes through 02 and reaches the base of the transistor 104 of the wake-up circuit 70. As a result, the transistor 104 is turned on, and the transistor 106 is also turned on. The actuation of transistors 104 and 106 raises the voltage on the VCC line to a maximum allowable DC voltage of about 5 1/2 volts. The voltage of the VCC line is 5
When it reaches 1/2 volt, the CPU 56 starts operating.

When activated, CPU 56 sets a signal on ALE line 108, which passes through resistor 110 and is filtered by capacitor 102. When the ALE signal is set, it creates a voltage at the base of transistor 104,
The transistor 104 is kept on and the transistor 106 is also kept on to keep the CPU 56 in the run state.
The CPU 56 naturally turns off by executing a HALT instruction to stop the ALE signal, turning off the transistors 104 and 106, eliminating power to the CPU 56 via the VCC line.

Note that the wake-up circuit 70 is activated by pressing the key (button) 25 or by an input signal at the serial port 3 coupled to the input port 112 of the CPU 56.

The aforementioned circuit elements are wake-up circuits for activating the operation circuit 42 of the remote control device 10.
Form 70. This circuit 70 is a substrate static protection diode (substrate static-p) in a CMOS chip coupled to a keyboard 61.
rotection diode) 114 is used. Due to this arrangement, when the key (push button) 25 is pressed, the power supply current (source cur
rent) is supplied.

The RAM 54 is connected to the lithium battery 52 and draws about 20 nanoamps from the battery 52 when the remote control device 10 is not in use, which gives the remote control device 10 a life of 5 to 10 years. The backup capacitor 116 is coupled to the RAM 54 and
Has a discharge time of 10 minutes (at 20 nanoamps),
It provides sufficient time to replace the battery 52 without destroying the instructions and data stored in RAM 54 (if needed). Capacitor 116 is continuously charged by battery 46 via diode 117 when remote control device 10 is operating, and is charged by battery 52 via diode 118 at other times.

After CPU56 powers up, that is, wakes up, C
The PU 56 uses each horizontal line 121 that leads to the keyboard 61 to detect which button, for example button 25 ', has been pressed.
To 128 are sequentially forced to be low, and the other lines are polled to scan the horizontal lines 121 to 128. For example, when push button 25 'is pressed, a row impressed on horizontal line 121 causes a row on vertical line 138 and a horizontal line 128.
To the low state.

CPU56 first sets horizontal line 121 low, then horizontal line 121
Starting from 122, the scan of another horizontal line with a low voltage is started, and the CPU 56 detects the horizontal line 128, which is the low voltage horizontal line as in the above example, so that the CPU 56 can detect the horizontal line 12.
Know that button 25 'has been pressed at the intersection of 8 and vertical line 138.

If, after setting horizontal line 121, CPU 56 has not found a low on another horizontal line, for example horizontal line 128, horizontal line 121 is returned to its previous value and horizontal line 122
Is set low and scanning continues until a row of low lines is detected to identify which button 25 was pressed.

When the CPU 56 determines which push button 25 was pressed, the CPU 56 can know which function will be performed.

Keyboard circuit 62 has eight horizontal lines 121 to 128
And register 64 and current directing (dire
cting) diode 114 and unique to include only eight vertical lines 131 to 138 arranged across horizontal lines 121 to 128 and configured to have only eight switch positions. Is designed to.

All memory cycles used must engage latch 58. Because the CPU 56 has its data bus on lines 141 to 148 in the lower 8
The address bus of bit (multiple) (mul)
Because it is tiplex).

9 lines 108 and 141 to 1 from CPU 56 to latch 58
48 groups are in touch. One of those lines
108 transmits the ALE signal. Eight lines 141-148 between the latch 58 and the CPU 56 are multiplexed data and address bus lines. These lines have a lower 8-bit address bus. A series of multiplex lines is identified by reference numeral 150. Further, the five lines 151 to 155 have an upper 5-bit address bus, and have a total of 13-bit addresses.

Inverting OR gate 156 with one output line 158 and two input lines 160 and 162 together with ground line 164
It is coupled between PU56 and RAM54. Line 1
58 defines an output means for the RAM 54.

Therefore, when the CPU56 wants to read,
Activate either of the two input lines 160 or 162 leading to R gate 156. Line 160 is a PSEN line that tells RAM 54 that data can be received, and line 162 is R
A read output line (read output) telling the AM54 that the CPU reads the information stored in the RAM54.
line). The OR gate 156 combines the two lines and their function at line 158. In other words, the CPU 56 has a RAM to RAM 54 via the OR gate 156.
They say they want to lead the information accumulated in 54.

Circuit 42 also includes a write protect circuit that has a dual job of also being a low battery indicator circuit. Circuit 78 includes a resistor 170, a transistor 171, two resistors 172 and 173, and a Zener diode 174 connected as shown.
Is included.

A write enable line (wirte enable line) 176 is connected between the transistor 171 and the CPU 56.

When the CPU 56 wants to write information to the RAM 54, it places an address on the address bus lines 141 to 148 and 151 to 155, and lowers the lines 141 to 148.
Latch the bit address bus using ALE line 108 58
Strike to the data bus line 141-1
Place information at 48 and then bring write enable line 176 low.

When write enable line 176 goes low, the collector 180 of transistor 171 (write enable for RAM54) prevents line 178 leading to RAM54 from going low unless transistor 171 is turned on by a battery voltage greater than 4.3 volts. , Keep write protect of RAM. This condition is also created when battery 48 is low. The write enable line 176 also functions as a low battery detector. This is because a check is made to know whether writing to the RAM 54 will be executed when the program is executed. If not, this indicates a weak battery and the signal is sent to the user by blinking the red LED, LED4, five times.

LED4 includes one unit red LED and green LED, both
Emits a yellow light when the LED is in the on state, LED4
Note that is a three-color LED. Such three colors L
The ED4 facilitates communication of the remote control device 10 to its user by means of colors, numbers and optical blink sequences.

A clock circuit 182 including a crystal oscillator is coupled to the CPU 56.

The three serial ports 1 to 3 are coupled to the CPU 56, and include a port 1 which is a transmitting port, a port 2 which is a ground, and a port 3 which is a receiving port. Serial port 1 is horizontal line 12
The data is sequentially transmitted to the serial port 1 from the RAM 54 through the horizontal line 121 in the form of high and low by the CPU 56. Code data and / or RAM54
When it is desired to update the instructions therein, the input data is sequentially received by the serial port 3 and transmitted to the input port 112.

Three infrared emitting LEDs, LED1, LED2 and LED3, are connected in circuit 42 as shown.

Reset circuit 74 is connected as shown and includes two resistors and one capacitor coupled between the VCC line and reset line 184.

As explained in detail in the description relating to FIGS. 11 to 14,
The manufacturer of the remote control device 10 using known methods or the methods described herein with respect to FIGS. 12A-13C may be TVs, VCRs, CDs, cable converters or other devices controlled by a remote infrared transmitter. It would be to decode infrared codes that operate the various elements of the equipment.

Such an infrared code is deciphered, its data code and the instructions that generate it (Fig. 14).

(FIG. 10) and the remote control device 10 is programmed as described below.

Note that circuit 42 has no ROM, and all instruction code and code data is stored directly in RAM 54. This structure allows infinite upgrades within the field via serial ports 1, 2 and 3.

FIG. 10 shows the CPU 56 of the operation circuit 42 coupled to the special connector 204 adapted to be received by the CPU 56 of the operation circuit 42, which disables the CPU 56 and allows the RAM 54 to be programmed by the program computer 200. FIG. 3 is a perspective view of a program computer 200 installed. In essence, this function tristates the CPU 56, writes the RAM 54 to the initial instruction code, including the code for the serial port driver, in RAM 54, and then successively and in succession to other instruction codes and code data. By placing the RAM 54 in the address space of the computer 200 that writes To this end, the program computer
The 200 has data related to serial driver instructions and stored infrared codes for operating multiple electrical appliances such as televisions, VCRs and the like. A signal from the program computer 200 via the connector 204 disables the input and output of the CPU, and after the operation circuit 42 is mounted on the remote control device 10, the instruction code and data from the program computer are quickly transferred to the RAM 54, Moreover, input is made efficiently.

After the remote control device 10 has been used for some time and the RAM 54 needs to be updated with the instruction code and the data relating to the new product equipment on the market, the remote control device 10 has a new 9 to 3 pin (9 to 5 volt). Signal Coupling / Conversion Assembly 206

It includes a final catch-all category, which is called random because there is no ready-made distinguishable pattern of 0's and 0's.

In addition to these schemes, there are also transmitters that emit different continuous frequencies (CW) for each key, as is typically illustrated in Figure 11h.

Finally, some advanced transmitters do not use the carrier frequency at all, but instead send a stream of pulses encoded in the space between each infrared pulse as illustrated in Figure 11i.

Most transmission data modulation schemes have a higher level of data organization (organizati), which can also be called a keyboard encoding scheme that sends different data depending on the transmitter and the key pressed.

How to Match a Remote Control to Your Equipment The remote control 10 is suitable for most remote control TVs, VTRs,
You can control the cable converter and the CD player, but for that purpose, the user needs to do the input operation to match each device. The easiest way to do this is to step-and-set the remote control 10. You only have to do this once for each device you own.

To step and set the device 10, 1. First, press DO and Enter.

2. To instruct the device 10 which device to match, press the device selection button described below.

VCR1 Cable TV VCR2 CD 3. Aim the device 10 at the target device and try various function buttons to see if the device responds properly. Make sure you are close enough to the device and there is nothing to block along the way. Device 10
The light (LED4) at the tip of the LED always lights up in green when an infrared code is generated, or does not light at all unless a specific button code is generated.

4. If your device does not respond properly or at all, press DO1 to change device 10 to send the next infrared cordset in the built-in library, or change the previous cordset. Change device 10 by pressing DO2 to send.

5. When using DO1 or DO2 to step the setting of device 10 back and forth, the light blinks yellow with each step. The light will always flash red to inform you when you return to the starting settings for device 10.

6. DO to step through the entire code set
Use 1 and DO2 and keep trying those features until your device responds properly. The device 10 is then set to send the proper infrared code for operating your equipment.

7. When the device 10 appears to match properly, either press DO or press one of the instrument selection buttons to return the DO1 and DO2 buttons to normal function.

8. If your device responds to device 10, but some buttons malfunction, just continue.
Some devices react to the infrared code of other brand devices.

9. If you try all the codes in the device 10 internal library and your device does not respond, the cause is probably the code data that generates the infrared code for your device operation. This is because they have not entered.

Keyboard 61 Look at the keyboard. There are four button groups.

1. The device selection button tells the device 10 which device should be controlled.

VCR1 cable TV VCR2 CD 2. Basic function button is for your TV, VC
Used to control R, cable and CD. They operate much like a typical old remote control with buttons such as:

3. The extended function buttons can perform any special function of your device, such as color control, image control, tint control, etc. These buttons are identified by the letters below.

ACCEGBDFH4. The DO button executes the very powerful DO command described below.

Special functions In addition to the basic functions such as channel up and down, volume up and down that most TV remote controllers have, there will be special functions such as the following.

Color Up / Down Image Up / Down Color Up / Down Sleep Your VCR remote control may have the following additional special features.

Frame feed Channel up / down Your cable converter remote may have the following features:

Channel Recall Delete Your CD player remote control may have the following special features.

Repeat track programming Once you have matched the device 10 to your TV, VCR, cable converter, or CD player, you can use the device 10 to control all functions that were controlled by the old remote control device. You will notice that it also has some extra features that your old remote couldn't.

This device 10 can control a wide range of devices in this way, so there is no room to attach to the device 10 all possible function buttons of all remote controls. As an alternative, there are eight extended function buttons below, labeled A to H. Your T
To discover what these eight buttons control for V, VCR, cable converters, and CD players, do the following:

1. Get a pen and paper.

2. Press DO and then the buttons on device 10 (TV, VCR1, VCR2, cable, CD) to learn about special features.

3. Device 10 blinks "red" and "green" eight times. Write "R" each time it flashes red. Write "G" each time it flashes green. After writing, for example:

RRRGRRRG This is the "blink code" for your device. If it fails the first time, press the DO and device buttons again.

4. The same "R" and "G" that I wrote down after looking at Table 1
Find the sequence.

5. Read the special features chart next to the blink code. The A to H buttons tell you what functions control your device.

For example, your TV feature chart might look like this:

A: Color up C: Image up B: Color down D: Image down 6. To color up in this example, press the TV button (of course, if device 10 is already set to TV,
You don't have to press the TV button again, but it does not matter if you do). Then press A.

7. Press B to decrease color.
