Title: Method and apparatus for identifying words entered on dtmf pushbuttons
Inventor: RISKIN BERNARD N
IPC: H04M11/06
Filed: 1988-11-24
Granted: 1992-02-18
Abstract: METHOD AND APPARATUS FOR IDENTIFYING WORDS ENTERED  ON DTMF PUSHBUTTONS     ABSTRACT OF THE DISCLOSURE         The identity of a word entered on DTMF (Dual Tone Multi-Frequency)  pushbuttons  is  determined  by  identifying  letters according to their frequency in groups of 2s and 3s and up to n-letter groups.  Initially, a sender will type a word on a DTMF pushbutton pad.  Since each button represents three (3) possible letters, or four in the case of 7 (PQRS) and 9 (WXYZ), the system will look up the possible meanings for the word from an internal memory which includes a dictionary.  If the word does not exist in the dictionary, then the system will search against a Forward and a Reverse Dictionary to guess at the identity of fragments from the beginning and ending of the word.  Then it will guess the identity of each letter according to its relative frequency in groups of 3s known as Trigrams, or in groups of 2s known as Digrams.   The Trigrams are preferably arranged in five (5) files to identify the first, second, third and final letters of a word as well as any non-specified middle location.  The system can be extended to any letter grouping of size n where n is two or more.  Once identified, the word is stored as part of a message and then transmitted as ASCII digital information over a packet data network to a remote receiver where digital to voice synthesis converts the message into audio.  According to a simplified alternative embodiment, the words are guessed not letter-by-letter but word-by-word from a data bank in which words are stored according to the length, numeric equivalent and relative frequency.  Other delivery methods include alphanumeric pagers, FAX, E-Mail, telex, computer printed output, telegrams and cables.

Abstract: ABSTRACT Apparatus for accurately and more safely monitoring blood and bodily fluids in a patient. In one embodiment, at least one load cell supports a container for receiving various sizes of sponges that hold such fluids. The sponges may be sorted into the container utilizing a sorting grid located above or forming a part of the container, and photoelectric or other sensors detect the number of sponges placed into the container via each opening in the grid. The load cells and sensors are connected to controller circuitry which counts, tracks and displays the number of each size of sponges in the container and the weight of fluid in the sponges. The weighing apparatus may be connected to a computer that is programed to read information from the weighing apparatus and from its own keyboard to calculate, update, store, display and print values corresponding to amounts of suction products, urine, crystalloids, irrigation, miscellaneous blood products including whole blood, fresh frozen plasma, packed red blood cells, platelets, cryoprecipitates and stimates introduced to or removed from the patient. The processor of the weighing apparatus may be adapted to perform the computer's functions in order to reduce the size of the apparatus. Alternatively, a computer without a weighing apparatus may be used to account for the values mentioned above, in which case the operator manually enters information relating to numbers and weights of sponges.
