Infusion controlling apparatus and method

Abstract: Portable electronic medical apparatus for controlling the flow rate of a fluid for medically treating a patient may receive flow rate information representing sequences of up to 20 flow rates and their durations from an individual and from an electronic data processor, and operate continuously without the presence of an operator for in the range of 40 hours. Upon the incorporation of an infusion pump into the apparatus, the desired regimen of treatment may be accomplished; and through a keyboard input for the apparatus, an operator may in certain respects modify a regimen which is being carried out. Safety features in the apparatus include: a frequency detector for monitoring the frequency of a clocking signal for the apparatus; the selective testing of output signals of the apparatus, the portable power supply for the apparatus and the frequency detector against stored predetermined standards; and the provision of warning signals to an operator to indicate divergences from such standards. Additionally, fail safe signals for the apparatus are coupled to relay circuitry to interrupt the output of the apparatus if a central processing unit for the apparatus enters undesired modes of operation.

Resonance Raman spectroscopy in biochemistry and biology.

Abstract: Resonance Raman (RR) spectroscopy provides detailed information on the vibrational and electronic properties of biochemical and biological chromophores. The analysis of RR spectra, using for example model compounds or a group frequency approach, enables us to form an accurate structural picture of the chromophore in its natural biological site. Moreover, the insight gained into the electronic states of a biological chromophore can be crucial to our understanding of its function. Thus the RR technique represents a powerful means of eliciting precise structural and electronic data from a coloured species and of focusing upon key aspects of its function. It has even been possible to obtain RR spectra from some natural chromophores in vivo, giving spectra detailed and informative enough to please a spectroscopist from a system complex enough to satisfy a biologist.

Three phase line-addressable serial-parallel-serial storage array

Abstract: Disclosed is an electronic data storage of the type wherein data is entered and read out serially. In a conventional serial-parallel-serial configuration, data is serially entered into an input register and then transferred and stored in parallel through the main section of the storage until data is transferred in parallel to the output register from which the data is read serially. In a conventional line-addressable configuration, data is entered into and read from columns of shift registers where each column is addressable. The disclosed array combines the conventional serial-parallel-serial and the line-addressable structures into one array. By utilizing three phase clock lines and an inhibit line for each cell, the disclosed structure can be fabricated with two levels of gate electrodes.

Line-addressable serial-parallel-serial array

Abstract: Disclosed is an electronic data storage of the type wherein data is entered and read out serially. In a conventional serial-parallel-serial configuration, data is serially entered into an input register and then transferred and stored in parallel through the main section of the storage until data is transferred in parallel to the output register from which the data is read serially. In a conventional line-addressable configuration, data is entered into and read from columns of shift registers where each column is addressable. The disclosed array combines the conventional serial-parallel-serial and the line-addressable structures into one array. This permits serial data to be read one row at a time as well as one column at a time.

The microscale sensing array

Abstract: A moored self-recording instrument designed to measure the fine scale temperature and velocity vector variability of the ocean in a vertical plane containing the mean velocity vector is described. (Since the conception, design, and naming of the microscale sensing array (MSA) the scale designation of phenomenon with wave lengths in the range (0) 1 to (0) 10 m has been changed from ‘mieroscale’ to ‘fine scale.’) The structure holds 16 water velocity sensors (propellors) and 14 water temperature sensors (thermistors). These sensors are mounted along two vertical masts, each 8 m long, separated horizontally by a 20-m spar. The whole structure is rigid, buoyed by two aluminum spheres, each 1 m in diameter, providing a net buoyancy for the instrument of about 386 kg. Contained within the spheres are an electronic data acquisition system, a magnetic tape recorder, primary batteries, a compass, and accelerometers to measure roll and pitch attitude. A separate cylindrical housing contains a pressure transducer and preamplifiers to sense depth. Provision is made to measure MSA translational motion by means of an acoustic transceiver and remote transponders. Instrument life is primarily dependent upon tape storage (53 million bits) and data sampling rate, which is easily preset to various continuous or burst modes. Maximum allowable operating depth is presently 900 m. The MSA has been deployed four times in the main thermocline southeast of Bermuda and once in the New England Continental Shelf bottom boundary layer.

Control of electronic display and print elements - using coding, transfer and display elements to generate required currents from duty cycle set by micro-processor

Abstract: A device for controlling electronic display and print elements for data output of electronic data acquisition equipment, non-automatic printers, cash registers, measurement printers and teletypes is designed for more economical generation of the current levels required for the display and print functions. The devices used for coding, transfer, and display of the output characters are also used to generate the required current levels. Luminescent or laser elements of a display and print matrix are driven intermittently by columns by a pulse train whose duty cycle is set by a microprocessor to one of two levels corresp. to display or print operations.

Fire protection walls for rooms or storage cabinets - using substance which has high latent heat and exhibits supercooling

Abstract: Wall for protecting rooms or cabinets from fire, includes a layer (a) which high thermal capacity. Layer (a) contains a pure crystalline substance (a1) which, after melting, undergoes supercooling; and substance (a1) has a transformation temp. (t1) from the solid to the liq. phase which is below the safety temp. (tx) of the room or cabinet being protected from fire. Substance (a1) is pref. housed in numerous individual containers, each surrounded by a layer (b) of thermal insulation. The containers are pref. arranged in a row in the direction of heat transfer. Used e.g. for the protection from fire of electronic data stores; safety rooms for humans in burning houses; or bankers for protection against atomic explosions.

Fluid dispenser digital electronic data system - has pulse generator coupled to dispenser giving enable pulse for liquid batch dispensed

Abstract: Data system for use in a fluid dispenser for producing an output signal corresponding in direct proportion to the accumulative cost of the fluid dispensed dependent upon a variable preset signal representative of a price for each unit volume of fluid actually dispensed comprises pulse generator coupled to the dispenser for generating an enabling pulse for each predetermined fraction of a unit quantity of liquid dispensed. An oscillator is operable between an idle condition and an activated condition in response to a disabling pulse and the enabling pulse respectively, for generating an idle signal and a burst of pulses; Presettable switch is manually movable through several positions for generating continuously a coded signal of varying weight proportional to the selected price for each unit volume of fluid; Registry mean are connected to the presettable switch to receive the coded signal and to the oscillator to receive the burst of pulses for producing the disabling pulse when the number of oscillator burst of pulses is equal to the coded signal; Counting means including dividing means are connected to the oscillator to receive the number of burst of pulses for dividing the number of pulses by the predetermined fraction of a unit quantity to generate an output signal proportional to the accumulated cost of the increment of fluid dispensed.
