    Abstract: A host device for use with a removable peripheral apparatus having a microphone, and to the biasing circuitry for said microphone. The host device may have a device connector for forming a mating connection with a respective peripheral connector. A source of bias is arranged to supply an electrical bias to a device microphone contact of the device connector via a biasing path. A capacitor is connected between a reference voltage node and a capacitor node of the biasing path. A first switch is located between the capacitor node and the device microphone contact. Detection circuitry detects disconnection of the peripheral connector and device connector; and control circuitry controls the switch to disable the biasing path.

  • Publication number: 20160113771
    Abstract: A femoral head resurfacing implant is described comprising an external articulating surface and an internal fixation surface. A stem projects from the center of the internal fixation surface. The internal fixation surface comprises a top surface, surrounding and substantially orthogonal to a long axis of the stem, a chamfer surface extending downwardly and outwardly from the top surface and a side surface extending substantially parallel to the long axis of the stem. At least one projection is arranged on the internal fixation surface to provide a predetermined gap between the top surface and/or chamfer surface and a resected head onto which the implant is to be fitted. Furthermore, the side surface constitutes or comprises a cement containment feature configured to restrict or eliminate outflow of cement from the predetermined gap.

  • Patent number: 9300212
    Abstract: Methods and apparatus for control of DC-DC converters, especially in valley current mode. The DC-DC converter is operable so that a low side supply switch may be turned off, before the high side supply switch is turned on. During the period when both switches are off the current loop control remains active and the change in inductor (L) current is emulated. One embodiment uses a current sensor for lossless current sensing and emulates the change in inductor current by holding the value of the output of the current sensor (ISNS) at the time that the low side switch turns off and adding an emulated ramp signal (VISLP) until the inductor current reaches zero. Embodiment employing a pulse-skip mode of operation based on a minimum conduction time are also disclosed. The invention enables a seamless transition from Continuous Conduction Mode the Discontinuous Conduction Mode and Pulse Skipping and provide converters that are efficient at low current loads.

  • Publication number: 20150190236
    Abstract: A knee prosthesis comprises a femoral component for securement to a femur, the femoral component defining medial and lateral condyles and an intercondylar groove; and a tibial component for securement to a tibia, the tibial component having respective bearing surfaces shaped to engage with said condyles both when the knee, in use, is extended and also over a range of flexion. The femoral and tibial components together comprise interengaging means, for stabilising against antero-posterior relative movement of the femoral and tibial components. One of the condyles and the respective bearing surface of the tibial component are at least partially congruent, at least at angles of flexion below a predetermined angle. The other bearing surface is incongruent with the other condyle in at least the antero-posterior direction so as to allow for antero-posterior movement of the femoral component relative to the bearing surfaces of the tibial component.

  • Publication number: 20150099949
    Abstract: Methods and systems are presented for displaying physiological information with a physiological monitor. A physiological parameter, for example oxygen saturation, is computed from a received physiological signal, for example a PPG signal. At least one metric associated with the received physiological signal is determined, for example a statistical measure of uncertainty associated with the determined physiological parameter. Display parameters are determined, for example a width parameter, based on the metrics and a trace of the computed physiological parameter for a subject is displayed. In some embodiments, the width of the displayed trace may be varied based on the width parameter. In some embodiments, additional or alternative characteristics of the displayed trace may be varied based on respective display parameters.
