  • Patent number: 8224064
    Abstract: A biometrics system captures and processes a handprint image using a structured light illumination to create a 2D representation equivalent of a rolled inked handprint. The biometrics system includes an enclosure with a scan volume for placement of the hand. A reference plane with a backdrop pattern forms one side of the scan volume. The backdrop pattern is preferably a random noise pattern and the coordinates of the backdrop pattern are predetermined at system provisioning. The biometrics system further includes at least one projection unit for projecting a structured light pattern onto a hand positioned in the scan volume on or in front of the backdrop pattern and at least two cameras for capturing a plurality of images of the hand, wherein each of the plurality of images includes at least a portion of the hand and the backdrop pattern.

  • Patent number: 7146843
    Abstract: The present invention relates to Deadweight Pressure Testers used for the calibration of air pressure transducers. An air pressure transducer, which is to be calibrated, is set in parallel with the deadweight tester. Air is slowly pumped into the cylinder and the pressure inlet of the said pressure transducer to be calibrated. The air, which enters the cylinder under pressure, exerts a force on the cylindrical piston, thereby lifting the piston and balancing it against the air pressure. This force is balanced by the weights loaded on the top of the cylindrical piston. When the air pressure and the weights balance, the air pressure is known from the weights and the diameter of the cylindrical piston. A thin rubber seal allows for low friction and low air loss providing greater accuracy in measurements.

  • Patent number: 5485833
    Abstract: Breath Exposure Synchronizer senses respiratory activity and indicates when it is the proper time to expose X-ray film to prevent blurring of radiographs due to voluntary motion of breathing. It indicates inhalation, when the breath is held, exhalation, and acts as a monitor to detect breathing in humans and animals.When used with Magnetic Resonance Imaging, it has the advantage of having no electrical connections to the patient. Electrical currents can be induced in electrical connections by the radio frequency magnetic fields used during imaging that can be harmful.Breathing is detected by a single use nasal cannula sensor.

  • Patent number: 5485850
    Abstract: A monitor that provides data obtained from the detection of very low positive, negative, or differential pressures, and can be used to control devices in health care and industry. An example of its use in health care is as a respiration monitor providing data that can be used to control devices associated with breathing while providing constant surveillance of the fundamental characteristics of air-breathing humans and animals. In industry it can act as a monitor that provides data by sensing very low pressures (negative, positive or differential) at intervals that can be used to detect positioning of low weight parts or act as a touch sensor for robotic equipment. Monitor detects pressure intervals by use of a vane type capacitance sensor capable of detecting pressures as low as 0.001 ounce per square inch. Monitor uses a micro-controller to control devices from data, obtained from sensor, by storing programs that govern, in predetermined manner, the operation of devices.

  • Patent number: 5074299
    Abstract: A monitor for controlling the flow of respiratory gases to only occur and be maintained as long as a human user of the monitor inhales. The monitor can function by sensing inhalation or exhalation by either use of a nasal cannula or a pneumatic breathing belt that detects body movements due to breating by the human user.

  • Patent number: 5052400
    Abstract: An inhalation sensor which uses a non-metallic diaphragm that is metallized on one side, pre-stressed, and used as one plate of a variable capacitance pressure tranducer to sense the inhalation and exhalation of air from the nostrils and/or mouth of a patient. The inhalation sensor is used for inhalation therapy by triggering a prescribed dose of therapeutic gas when inhalation takes place. The inhalation sensor can also be used as a monitor to detect apnea (the absence of breathing).

  • Patent number: 5038771
    Abstract: A method and apparatus for sensing when inspiration takes place during breathing cycles of air-breathing animals, including humans, that triggers a dose of respiratory gas to be inhaled when inhalation begins. The dose of the respiratory gas determined by the length of the previous breath, whereby it follows from the foregoing that the dose of respiratory gas is automatically adjusted to the rate of breathing of the air-breathing animals, including humans.

  • Patent number: 5024219
    Abstract: A triggered dose oxygenator using an optoelectronic inhalation sensor to trigger a dose of breathable gas, including oxygen, from one of four possible sources of supply to a human user when the user of the triggered dose oxygenator inhales. The four possible sources of supply are: a large tank of breathable gas, a small tank of breathable gas on a wheeled portable cart, a wall outlet supplied from a bulk storage system of breathable gas, and an oxygen concentrator supplying oxygen from ambient air.

  • Patent number: 5005571
    Abstract: A mouth nose mask used in combination with an inhalation therapy and/or breathing monitoring apparatus, the mask is mounted on the face of a patient independently of a nasal cannula and over the cannula without impeding its function. The mask makes it possible for the cannula to carry out a dual function of providing inhalation therapy and breathing monitoring both through the nasal passages of the patient and oral cavity of the patient. The mask has no connections to the inhalation therapy and breathing monitoring apparatus and is worn over the nasal cannula. In use, the treatment gaseous fluid is delivered to a patient through the nasal passages in communication with the nasal cannula. The mask provides for diversion of some of the oral inhalation air to the nasal cannula to sense inhalation in the event that the upper nasal passages of the patient are blocked.

  • Patent number: 4878502
    Abstract: Breathing sensor that monitors the inhalation and exhalation of air by sensing the flow of air from a patient's nostrils or by expansion and contraction of the chest, abdomen, side or back. The respiration sensing is changed to an electrical signal that indicates and provides an output signal for monitoring the breathing function. The sensor comprises a housing with a tubular passage containing a ball, a tube connection, a light source, means for detection when the ball interrupts the light source, and an electronic circuit that provides a breathing indicator and output voltage suitable for use in monitoring the patient's breathing.

  • Patent number: 4602643
    Abstract: A respiration monitor comprising a sensing unit which senses the expansion and contraction of the chest, abdomen, side or back, by pneumatic means. Expansion of the chest is changed into a positive flow of air (pressure). Contraction of the chest is changed into a negative flow of air (vacuum). The sensor in the form of a belt with minimum space maintaining tapes is worn by the patient and connected to an appropriate monitor by means of tubing. The minimum space maintaining tapes allows the patient freedom of movement and prevents such body movements from affecting the operation of the sensor.
