Abstract: A transtelephonic process and storage apparatus (10) for use with a blood sugar monitor or like standalone monitoring apparatus having an output port to download acquired digital data signals is disclosed. The apparatus (10) has a memory (18), a controlling (14), a transducer (17) and an output (12), wherein the downloaded acquired digital is converted into audio transmission signals by the transducer (17), and the audio transmission signal is stored in memory (18) for delayed transmission over a telephone network.

Abstract: A method synchronous parallel transmission of digital signals over a telephone line is disclosed. The method includes the steps of generating a synchronization signal having at least two frequencies (6 and 7), simultaneously generating data signals having at least two separate frequencies from the digital signals, converting the synchronization signal and the data signals into audio signals having frequencies corresponding to frequencies of the synchronization signal and the data signals to be transmitted over the telephone line and transmitting at least three frequencies of the audio signals simultaneously over the telephone line.

Abstract: A hand held, portable and multipurpose medical device for biological signals acquisition, display and storage. The device includes a multipurpose computerized apparatus (2) which is primarily used for computer games as well as a biological signals acquisition module (1) which uses a plurality of biological sensors (6). A cartridge (4) used in conjunction with the computerized apparatus is pre-programmed and includes a read only memory (ROM) for storage of the program and a random access memory (RAM) for storage of acquired data. The acquired data in one form is an ECG and the apparatus simultaneously acquires and displays the ECG waveform in “real time”. Multiple memories in the apparatus are used for storage of the acquired ECG and to enable output to a printer (8) for hard copy or to a PC for analysis and reporting.

Abstract: A diagnostic medical device which monitors physiological parameters during sleep is disclosed. The device includes mask means (2) adapted to fit over the nose and mouth of a patient being monitored, and an acquisition unit (5) is adapted to be removeably fitted to the mask means (2). The mask means (2) has inlet means (3) to allow the patient to breath, sensor means (8) which monitor physiological conditions and which provide physiological signals thereto for storage or real time data transmission to external devices.

Abstract: A physiological monitoring apparatus comprising a cellular phone handset connected to a cellular phone network is disclosed. The handset includes a removable battery container (12) having a physiological monitoring device (14) contained therein as well as a battery power source (13). The battery power source (13) provides power for the operation of the handset (11) as well as providing power for the physiological monitoring device (14). The battery container (12) has detectors (15) located on its outer surface, communicating with the physiological monitoring device (14) through apertres in the battery container (12). Acoustic coupling means (18) are adapted to couple tones produced by the physiological monitoring device (14) with a sound microphone of the cellular phone handset. The physiological monitoring device (14) is activated by placing it against the chest of a patient and the cellular phone handset is used to connect to a remote monitoring station via the cellular phone network.

Abstract: A nonwoven textile fabric comprising a batt of nonwoven filaments and having at least a portion of the filaments extending outwardly from one face of the batt to form a raised pile. In one embodiment at least a portion of the filaments are fused together on one side of the batt forming a fused face, and the raised pile extends outwardly from the fused face. In another embodiment, the batt has a fused face on each side thereof and the raised pile extends outwardly from one of these fused faces. In still another embodiment, the batt has a single fused face and the raised pile extends outwardly from the side of the batt opposite the fused face. The textile fabrics are also disclosed with an adhesive and/or a backcoating layer on the side opposite the raised pile. Method and apparatus for the production of the nonwoven textile fabrics are also disclosed which employ needle punching the nonwoven batt with forked needles to provide the raised pile.

Abstract: A method and apparatus are provided permitting shifting from rolling a thermoplastic web upon one roll to rolling the thermoplastic web upon another roll by overlapping the web connected to one roll and the web connected to the other roll, severing the overlapped webs, and forming a seam between the overlapped ends of the webs.

Abstract: A nonwoven fabric is produced from a batt of staple fibers by passing the unneedled batt of staple fibers to at least two needling zones, each needling zone having a plurality of needles which move in a reciprocating motion having a first needling direction and a second needling direction, the needles in a first needling zone having barbs which catch staple fibers of the batt primarily when the needles move only in the first needling direction and the needles in a second needling zone having barbs which catch staple fibers of the batt when the needles move in both the first needling direction and the second needling direction.

Abstract: A nonwoven fabric is produced by forming a batt of fibers which are oriented primarily transverse relative to the direction of movement of the batt, stretching said batt longitudinally relative to the direction of movement of the batt, and needling the stretched batt. Also apparatus suitable for the production of the novel fabric is disclosed.

Abstract: A nonwoven fabric is produced by forming a batt comprising staple fibers oriented primarily in the fill direction, drafting the batt in the warp direction in a first warp-drafting zone, needling the drafted batt, drafting the needled batt in the warp direction in a second warp-drafting zone, and drafting the warp-drafted, needled batt in the fill direction in a fill-drafting zone. A fabric, apparatus for producing the fabric, and a method for fusing a nonwoven batt are provided.

Abstract: Nonwoven fabric is fed at a first rate into the bite between a first shredding element and a stationary working surface. The first shredding element has a plurality of projections which penetrate the fabric and at least substantially shred the fabric as the first shredding element is moved past the working surface at a second rate substantially greater than said first rate. The at least substantially shredded fabric then passes between the first shredding element and a second shredding element, the latter being driven at a third rate substantially different from said second rate to effect additional shredding and to separate the resulting staple fibers. A forced draft fan pulls air past the fabric as the fabric is being worked, to maintain the fabric temperature below the fusion temperature of the fibers.
