Definitions

  • the present invention relates to multifunction communications access systems and devices. More specifically the present invention relates to Cellular Telephones with enhanced capabilities to enable more flexible communications, including control interfacing. These systems and devices also have the ability to employ alphanumeric data entry and transmission for a wide variety of applications and to interface with multiple communications networks.
  • Cellular telephones have achieved widespread use primarily in automobiles but also as portables, transportables and hand-held portables. The greater acceptance in automobile use in part is attributable to the limited battery life of hand held cellular telephones, and to the weight and bulk of portables.
  • a hand held cellular telephone only will run for 5 to 15 hours in standby mode, and for 30 to 40 minutes talk time with a standard Nickel Metal Hydride battery. Additional bulky batteries can extend these times considerably.
  • a battery recharger is a very necessary part of the cellular telephone take along equipment even on relatively short trips away from the office or home.
  • Some cellular telephones on the market have pager-like features such as a vibration alert mechanism, but still have a short standby battery life, because these phones still operate on a standard cell system.
  • a typical paging device can run for nominally 1000 hours using a AAA 1.5v penlight battery with 650 mAH capacity. It uses a Frequency Shift Key carrier spaced at 25kHz with POCSAG digital code at 512bps.
  • buttons are arranged in four horizontal rows and three vertical rows. This arrangement is sometimes 16 buttons, or more on sophisticated designs, without departing from the concept of this technique, it is helpful to consider the arrangement as now commonly used to facilitate an explanation and further, to demonstrate the manifest simplicity and applicability to the production of a number of discrete information signals far exceeding the number of "push buttons" provided on the hand-set.
  • buttons With the existing arrangement, for example, the four horizontal rows of push buttons include 1-2-3, 4-5-6, 7-8- 9, and *-0-#, respectively, Figure 9.
  • the three vertical rows include 1-4-7-*, 2-5-8-0, and 3-6-9-#, respectively.
  • the buttons further include letters of the alphabet with the exception of the letters Q and Z. In this embodiment of the invention, the period ".” and the letters Q and Z are assigned to the "1" button in the order listed.
  • the first of six data entry techniques described is the Count Along the Button Entry Mode (CAB) which was first disclosed in U.S. patent No 4,427,848. This particular CAB mode was designed as the fastest means of data entry with the fewest number of key strokes.
  • the # key will invoke the "enter numbers only” feature.
  • the "2" through “9” keys are assigned to transmit the numbers and letters printed thereon.
  • the "1” key is assigned the “.”, “Q” and “Z” codes.
  • the "0” key is assigned the ",” “go to features levels", "space” and “shift upper/lower case” codes.
  • the numbers are entered directly, after selecting the # key.
  • the three letters that are on each key are sequenced on a key-by-key basis, and not for the entire key pad as is common with other modes.
  • the letters are selected by successive key depressions.
  • the first, second or third letter of each key are accessed by pressing one, two, or three strokes on that particular key.
  • the selected letter on the particular key is sent as soon as any other key is depressed. For example, two strokes on the "2" key will select the letter "B". However, the letter "B" is not sent until another key is depressed.
  • This mode is fast and easy to use and competes with most other modes since the user only needs to select the letter without depressing a separate "enter” key. Transmission of the letter occurs automatically when the user begins selecting the next letter.
  • the # or the * key may still be used as the "enter” key.
  • the first desired letter of the particular key is first selected by successive sequential strokes followed by a stroke of the # key to send the first desired letter. Although depressing any other key also will send the letter, the first letter of that key will be selected for the next transmission. Since the selected letter is sent after another key is depressed, direct audio response may be cumbersome and confusing. In preferred embodiments of this mode, audio response is relative to one or more words rather than to each letter, when it is used.
  • the data entry mode referred to as the Modified Count Along the Button Data Entry Mode is next described. It was first disclosed in U.S. patent No 4,427,848. In this mode, for example, the * key is used to sequence the letters in a manner similar to that described above. The # key will invoke the "enter numbers only" feature. Sequential strokes of the * key will sequence the letters.
  • the data entry technique is similar to the previously described mode. Numbers are entered directly after selecting the # key. Sequencing the letters is performed by successive strokes of the * key. Pressing one stroke of the * key causes the first letter on each number key to be ready for transmission when a number key is depressed. A second sequential stroke of the * key will sequence the key pad to the second letter position. A third sequential stroke of the * key will sequence the keypad to the third letter position. Another stroke of the * key will sequence the keypad to a fourth position or back to the first position. Any number of keys may be pressed between strokes of the * key. Each stroke of a number key will transmit the letter that corresponds to the number of sequential strokes of the * key that have been pressed at that time. Selecting the # key will reset the letter sequencer to its first position along with changing to the "enter number only" mode. This allows the # key to be used as a letter sequencer reset should the user wish to quickly return to the first position.
  • Another data entry mode is referred to as the Relevant Character Data Entry Mode and was first disclosed in U.S. patent No 4,427,848.
  • This mode can be used as a default mode since it offers a simple (Quickey ) method of alphanumeric data entry for short messages.
  • the # key will invoke the "enter numbers only” feature.
  • a short stroke (e.g. under 240 milliseconds) of the * key will invoke the "enter letters only” feature.
  • a long stroke (e.g. 240 milliseconds or longer) of the * key will cancel the last character that was entered in the buffer. Successive long strokes of the * key will cancel the entire last word, sentence or the entire buffer memory.
  • the "2” through “9” keys can transmit the number and letters that are printed on them.
  • the "1” key is assigned the period “.” and the letters “Q,” and “Z” in that order.
  • the "0” (OPER) key is assigned in addition to "0" any or all of the following: "space between words,” “go to command feature level,” and "verify last character”.
  • the numbers are entered directly after selecting the # key.
  • Letters are sequenced on each key by selecting a combination of short and long key strokes.
  • the operating system measures periods of inactivity following a short key stroke and will interpret them as a long key stroke. This will be referred to for the remainder of this discussion as a computer signal.
  • a long key stroke or computer signal enters the letter, while a short key will shift the selector to the next letter. For instance, two short strokes followed by a long stroke or signal on the "2" key will transmit the letter "C.” One long stroke or computer signal on the "2" key will send the letter "A. " The sequencer is set back to the first position each time a long stroke or key is engaged.
  • the Twin Depression Technique makes use of some properties of the tones generated by a touch tone keyboard. This technique was disclosed in U.S. patent No 3,381,276 and in U.S. patent No 3,647,973.
  • a touch-tone keyboard for example, is such that for any button pushed or otherwise actuated a Dual Tone Multiple Frequency (DTMF) is produced at the output.
  • DTMF Dual Tone Multiple Frequency
  • the frequencies developed can be considered to correspond to row and column numbers.
  • Al represents the frequency component common to first horizontal row, A2 the second horizontal row, A3 the third horizontal row and A4 the fourth horizontal row.
  • Bl represents the frequency component common to the first vertical column, B2 the second vertical column, and B3 the third vertical column.
  • push-button 1 when push-button 1 is depressed, frequency components Al and Bl are simultaneously produced.
  • Frequency component Al appears in the first horizontal row
  • frequency component Bl appears in the first vertical column.
  • the intersection of the first horizontal row with the first vertical column is push-button 1.
  • Simple computer control consistent herewith merely requires simultaneous depression or other actuation of two or more buttons in rows or columns. More particularly, it has been found that with the conventional touch-tone telephone handset, simultaneous depression of two or more buttons in any given row causes but a single discrete frequency component to appear at the output of the telephone handset. For example, if two push buttons corresponding respectively to the numerals 5 and 8 were simultaneously depressed, or otherwise actuated, only frequency component B2 would appear on the output of the telephone handset and thus be transmitted along the interconnection line. Frequency components A2 and A3 would not be present. When two push buttons corresponding respectively to numerals 2 and 3 are simultaneously depressed, the frequency component Al appears while frequency components B2 and B3 do not appear.
  • This procedure provides a technique which, as mentioned above, utilizes this capability to produce both command or control as well as alphanumeric data input signals to a computer.
  • any given piece of data whether it be alphabetical or numeric or in any language, and any given instruction or command signal can be represented by an instantaneous single output signal produced by the proper twin depression or other actuation of two or more of the push buttons existing on a standard push-button or "Touch- Tone" telephone handset.
  • the single output signal may consist of only one signal or frequency component according to the above example.
  • the single output signal may consist of two frequency components which, while harmonic in nature, are instantaneous.
  • a "reverse" logic also may be used wherein a signal output of one frequency component represents data information and a signal output of two frequency components represents command information.
  • This single signal technique permits a user of the system to perform only one operation for each piece of data and for each command given to a computer. Furthermore, this technique can yield a virtually unlimited number of single or multiple discrete output signals which can be produced merely by varying the number and particular button or buttons depressed or actuated.
  • a further data entry technique is the Straight Pass Through Data Entry Mode disclosed in the Comput-A-Talk
  • This particular mode is designed to be plug compatible with most conventional audio response systems using the Touch-Tone telephone as the input keyboard.
  • This data entry method permits the pass through of the 12 dual tone signals generated by pressing a Touch-Tone key.
  • the additional four available DTMF harmonic tones when a fourth column of keys is used are converted to ASCII A, B, C and D respectively.
  • the raw Touch-Tone signals are passed through without any translation.
  • the straight pass through technique does convert the Touch-Tone signals into bona fide ASCII codes.
  • 128 is added to the ASCII value transmitted from the system to a computer.
  • a short depression of the "1" key transmits an ASCII "1" (Decimal 49) while a long depression of the "1" key transmits an 8 bit binary number corresponding to ASCII "1" + 128 (or 177 decimal).
  • the straight pass through technique converts the Touch-Tone signals (#, *, 0-9) into bona fide ASCII equivalents of the #, *, 0-9.
  • the final data entry technique described is the Delayed Depression Data Entry Mode and is the subject of patent 3,618,038.
  • This mode allows the user to transmit most of the 128 characters defined by the ASCII standard including all of the numbers, the upper and lower case letters, and 30 punctuation marks and symbols.
  • the # key will invoke the "enter numbers only" feature.
  • a short stroke of the * key will cause the device to give a verbal verification of the last character that was entered.
  • Successive long strokes of the * key will cancel the last character, word, sentence or entire memory buffer.
  • the keyboard assignments will depend on the portion of the ASCII code that has been chosen for transmitting. Each key is assigned ten different characters. Numbers are entered directly after selecting a long # key stroke.
  • Letters, punctuation, and numbers are chosen by pressing long strokes on the "1" through “9” buttons.
  • a long stroke of the "1", “2,” and “3” choose respectively the upper case first, second and third letters of each such additional numeric key.
  • a long stroke of the "4", "5" and “6” keys select respectively the lower case first, second, and third letters of each subsequent key.
  • a long stroke of the "7", "8” and “9” will each assign a different punctuation and special character set to the keyboard.
  • Long depression of keys "0" through “9” may be used at any time during data entry, to select a different character or function set for transmission of desired data by short depressions of keys “0" through “9.”
  • the value that is transmitted by any short key depression will be defined by the last long key depression.
  • the present invention combines the features and functions of a cellular telephone and a Radio Paging Device.
  • the two personal communication functions are combined in a manner such that a signal that may not be integral to the current cellular call processing is used to activate power to the cellular telephone circuitry and enable it to receive an incoming telephone call.
  • Any signal can be used, however the preferred embodiment is a signal derived from an established communications signaling standard, which can be detected with a low power receiver.
  • An example of this is a radio common carrier signal that is used to activate a paging device.
  • Other examples of types of signals that may be used in this invention for call processing are D channel ISDN and DTMF signals similar to those used for call waiting and caller ID.
  • the advantage gained is that the cellular telephone circuitry does not draw as much power in standby mode in order to detect incoming calls.
  • This invention results in longer battery life and in the ability to use smaller and less costly batteries than those currently used to power cellular telephones.
  • the weight and size of a cellular telephone may also be reduced.
  • a cellular phone user may receive multiple messages when it is inconvenient to answer a phone call.
  • the user may be made aware of an incoming call or message without the use of an audible device.

  • the telephone number of the incoming caller can be stored in a rapid redial memory for one touch callback at the users option.
  • the rapid redial memory can be in the cellular telephone itself or elsewhere within the network, such as in the central equipment.
  • the telephone number can be automatically detected by means for identification of incoming telephone calls such as "Caller ID" or can be input by the caller.
  • the telephone can also include callback circuitry for automated initiation of a return call upon actuation of the telephone after a call is received if the cellular telephone was dormant or upon the user terminating the current phone if the incoming call was received when the user telephone was already activated and a call was in progress.
  • Any keypad is capable of sending alphanumeric symbols using a system as shown in Tsakanikas 4,427,848, which relates to a Telephonic Alphanumeric Data Transmission
  • Messages can be originated on the current invention or on any device with a ten, twelve, or sixteen button keypad.
  • the current invention or any electronic device with the appropriate circuitry can receive messages that originated from a keypad when a receiver/translator, as taught in the above noted Tsakanikas patent, is present at an appropriate place in the communications network.
  • This translation function may or may not be in the receiving device itself. This means that the invention will be able to send messages to similar devices or to paging only devices. This could be, but is not required to be, via a radio common carrier.
  • Messages can also be transmitted from device to device via the mobile carriers.
  • a message may further be encoded so that it is recognized by the receiving device to be a control signal.
  • This control signal may be, but is not limited to be, a command to the receiving device to change its mode of operation, to store program information in its memory, or to relinquish control to the originating device.
  • One embodiment of the invention is to form the housing of the current invention in the shape of a gun, with the message display or displays being situated on the device gun barrel and the keypad being situated on the device gun handle.

  • a single click of the "trigger" of the Comput-A-Gun is used to enter data and commands to the device memory and a double click may be used to send a message.
  • Further embodiments of the invention include interfaces to other communication devices and computing equipment.
