Title: Method and apparatus for monitoring the pelvic floor muscles
Inventor: BEN LEVY
IPC: A63B23/20
Filed: 2014-10-28
Abstract: Differentiating between strain and contraction of the pelvic floor muscle, PFM, of a subject comprises using an orientation sensor 112, e.g. accelerometer, geomagnetic field sensor, magnetometer or gyroscope sensor, provided within a vaginal probe 110. In one embodiment data is received from the sensor located within the vaginal canal. A processor 123 is utilised to determine from the data a direction of rotation of the probe during a measurement period. When the probe rotates in the cranial-ventral direction an output is generated indicating there has been a contraction of the PFM. When the probe has rotated in the caudal-dorsal direction an output is generated indicating there has been a strain of the PFM. In another embodiment the probe comprises a transmitter 113. An internal and external calibration period may be used to calculate noise within the subject and within the device respectively. The probe may comprise a force sensor 114 to detect compressive force acting on the probe.

Title: Rail head profiling device
Inventor: Zizwani Mhango
IPC: G01N27/83
Filed: 2015-02-05
Abstract: A rail track measuring device may use a plurality of Hall Effect sensors 2 arranged in horizontal and vertical axes around a rail 3. The arrays act to determine the distance between themselves and the rail by measuring the corresponding magnetic flux density. Due to the curved profile of the rail 3 the values differ, they are sent to a processor (not shown) and software plots the position of the measured values [Fig 3, 1 and 3]. A profile of a train wheel [Figure 3, 2] may be superimposed on the plotted value [Figure 3, 3] to determine contact points between the rail and wheel. It is thus possible to determine if safety warnings should be issued relating to rail wear. Rail head and side wear can also be determined.

Title: Perpendicular spin transfer torque (STT) memory cell with double MgO interface and CoFeB layer for enhancement of perpendicular magnetic anisotropy
Inventor: SANGMUN OH
IPC: H01L43/10
Filed: 2016-03-11
Abstract: A perpendicular magnetization anisotropy (PMA) spin transfer torque (STT) magnetic tunnel junction (MTJ or TMR) forming a Magnetoresistive random access memory (MRAM) device. The STT-MTJ device has a CoFeB alloy free layer 104 located between the Magnesium Oxide MgO tunnel barrier layer 106 and a further upper MgO capping layer 130, and a CoFeB (Cobalt Iron Boron) alloy enhancement layer 140 between the MgO capping layer and a non-magnetic Tantalum (Ta) cap 150. The STT-MTJ device further comprises a ferromagnetic reference layer 102 (preferably comprising CoFeB), and an insulating tunnel oxide barrier layer 106 between the reference and free layers. The reference 102 and fixed free layers 104 have a fixed or programmable (switchable) perpendicular magnetization anisotropy PMA (respectively). The CoFeB alloy free layer has high Iron, Fe content (>25% atomic concentration) to induce perpendicular magnetic anisotropy (PMA) at the interfaces with the MgO layers. To avoid creating unnecessary PMA in the enhancement layer due to its interface with the MgO capping layer, the enhancement layer has low Iron Fe content (<4% atomic concentration). After all of the layers have been deposited on a substrate, the structure is annealed to crystallize the MgO. The CoFeB alloy enhancement layer inhibits diffusion of Ta from the Ta cap layer into the MgO capping layer and creates good crystallinity of the MgO by providing CoFeB at the MgO interface.

Filed: 2016-09-19
Abstract: An attenuated total reflection (ATR) objective 30 for use in a scanner includes first 32 and second 31 optical elements and an input port 35. The input port 35 receives an input collimated light beam 39, usually produced by a quantum cascade laser, that is focused to a point 38a on a planar face 34 of the first element 32 by the second element 31 such that substantially all the incident portion is reflected by the planar face and no portion of the beam 39 strikes the planar face 34 at an angle steeper than the critical angle by using a mask 33 to block the middle portion of beam 39. The second optical element 31 generates an output collimated light beam from light reflected from the planar face with a central ray that is coincident with the central ray of the input beam. A light beam converter (65, 66, fig 6) receives the first output collimated light beam and generates the input collimated light beam therefrom in response to an orientation signal. The light may be mid-infrared light and the second element 31 may focus the light by refraction (i.e. lenses) or reflection (i.e. mirrors (41, 43, fig 4)).
