Patent Title
Sensor incorporating multiferroic materials for detecting both electric and magnetic fields

Patent Number & Issued Date
9,470,733
ctober 18 2016

Inventor Names
Baglio* Salvatore, Andò* Bruno, Bulsara Adi Ratan, Beninato Angela, Emery Teresa

Abstract
A sensor for detecting both magnetic fields and electric fields can include at least one Sawyer-Tower (ST) circuit that can incorporate a multiferroic capacitor. An odd number of ST circuits coupled together in a ring configuration, so that for each ST circuit, the output of one ST circuit is an input to another of the ST circuits. The multiferroic capacitors can include a multiferroic layer that can be deposed on a substrate. For each multiferroic capacitor, the deposition process can cause an inherent amount of impurities in the multiferroic layer. The number of said odd number of ST circuits to be coupled together is chosen according to the amount of impurities, to "forgive" the impurities. The higher the level of impurities in the multiferroic layers, that more ST circuits that are required in the ring to achieve the same sensor sensitivity. BDFO can be chosen for the multiferroic material.

Patent Title
Method and apparatus for obtaining cardiovascular information by measuring between two extremities

Patent Number & Issued Date
US 9,510,761 B2
December 6, 2016

Inventor Names
Ramon Pallàs Areny, Ramon Casanella Alonso, Joan Gómez Clapers

Abstract
A method and an apparatus for obtaining information on a cardiovascular system beat by beat and continuously which are based exclusively on measurements between two limbs and effected with a pair of distal electrodes on each limb. The measurement is made by causing an alternating current to flow between one electrode of each limb and measuring the potential difference between the other two electrodes, one also on each limb. This potential difference has a low frequency component which is an electrocardiogram (ECG) and another component having a frequency of the injected alternating current and from which an impedance plethysmogram (IPG) is extracted. The cardiovascular information is determined by measuring the time interval between any predefined characteristic element of the ECG and one of the IPG.

Abstract
A method of drilling a well is disclosed. A first estimate is obtained of a location of the well with respect to a reference well at a selected depth. A magnetic measurement is related to a residual magnetic charge distribution in the reference well. An expected value of the magnetic measurement at the selected depth is determined from the residual magnetic charge distribution. A second estimate is obtained of the location of the well using the first estimate of the location, the obtained magnetic measurement and the expected value of the magnetic measurement. A drilling parameter of the well is altered using the second estimate of the location.

*indicates IMS member

Abstract
A needle-free transdermal transport device for transferring a substance across a surface of a biological body includes a reservoir for storing the substance, a nozzle in fluid communication with the reservoir and a controllable electromagnetic actuator in communication with the reservoir. The actuator, referred to as a Lorentz force actuator, includes a stationary magnet assembly and a moving coil assembly. The coil assembly moves a piston having an end portion positioned within the reservoir. The actuator receives an electrical input and generates in response a corresponding force acting on the piston and causing a needle-free transfer of the substance between the reservoir and the biological body. The magnitude, direction and duration of the force are dynamically controlled (e.g., servo-controlled) by the electrical input and can be altered during the course of an actuation cycle. Beneficially, the actuator can be moved in different directions according to the electrical input.

Patent Title
Time synchronization and controlled asynchronization of remote trigger signals

Patent Number & Issued Date
US9331842
May 3, 2016

Inventor Names
Robert H. Flake*
*indicates IMS member

Abstract
A mechanism is disclosed for transmitting pulses onto respective cables so that the pulses arrive at the remote ends of the respective cables in synchronized (or controllably asynchronized) fashion. First, the round-trip time of flight of each cable is measured using speedy delivery pulses, i.e., pulses whose leading edges have exponential shape. Second, a calculation is performed to determine the input delay(s) between the pulses that would produce desired output delay(s). For example, it may be desirable that the pulses arrive at the respective remote ends at the same time, in which case the desired output delay(s) is (are) zero. Third, the same speedy delivery pulses are transmitted onto the respective cables so that the interpulse delay(s) conform to the computed input delay(s). Thus, the desired output delay(s) are achieved at the remote ends of the cables.

Patent Title
Three-Dimensaional Holographical Imaging

Patent Number & Issued Date
Australian 2013337368
September 22, 2016

Inventor Names
Mohammad Tayeb Ghasr*, and Reza Zoughi*
*indicates IMS member

Abstract
A holographic imaging system including a transmission line coupled to an antenna at one end and to a signal source at another end. The antenna defines an aperture through which a signal generated by the signal source is transmitted incident to an object located remotely from the aperture and through which a signal reflected from the object is received by the antenna aperture. A standing wave probe phase-referenced to the antenna aperture samples the reflected signal. A detector connected to the standing wave probe receives the sampled reflected signal and provides an output signal that represents a real-valued signal proportional to an in-phase component of the reflected signal from the object. A processor executes an imaging algorithm for generating a multi-dimen sional profile representative of the object based on the output signal from the detector.
