Abstract: A robotic surgical arm including a receiver configured to receive wireless communications from a robotic surgical instrument attached to the robotic surgical arm and a shield including a plurality of fingers each having a common shape and a connector being in contact with each of the fingers. When the connector is electrically connected to ground, the shape, dimensions and arrangement of the fingers causes attenuation of the transmission of electric fields through the shield.

Abstract: Magnetic positioning systems and methods for use in a robotic surgical system are provided. A multi-axis magnetic field source generates a magnetic field by simultaneously exciting a plurality of axes of the multi-axis magnetic field source with respective source signals that are orthogonal to each other over a period, T. A multi-axis magnetic field sensor detects the generated magnetic field. The detected magnetic field is analysed over an analysis interval which is at least as long as the period, T, to resolve the detected magnetic field into components which are due to the plurality of source signals. The components are used to determine one or both of the position and the orientation of the multi-axis magnetic field sensor relative to the multi-axis magnetic field source.

Abstract: Systems and methods are disclosed for autonomously soothing babies. An example method may include receiving a first sound input from a microphone, processing the first sound input, determining a baby status based at least in part on the first sound input, determining an output action based at least in part on the baby status; and implementing the output action at the children's apparatus.

Abstract: A device for detecting an incident light distribution. The device has an array of light sensors, and a shadow casting element spaced above the light sensor array, with the shadow casting element between the incident light to be modeled and the sensor array. A processor interprets a cast shadow detected by the light sensor array thereby to derive information relating to the directional distribution of the incident light.

Abstract: We describe an electric toaster or grill for toasting or grilling foodstuffs and the like, comprising: at least one electric heating element for toasting or grilling a foodstuff; and a browning sensor located to receive an air flow from said toasted or grilled foodstuff said air flow entraining particulates from said toasting or grilling; wherein the browning sensor comprises: preferably an electrically conductive chamber or cage including an aperture to enable said air flow including said entrained particulates to pass through the chamber or cage; an ion emitter comprising a heatable electrical conductor; a heating circuit to pass an electrical current through said heatable electrical conductor to heat said electrical conductor to generate ions from said the particulates entrained in said air flow; an ion current sensing electrode to receive said ions from generated from said particulates; a bias circuit to electrically bias one of said heatable electrical conductor and said ion current screening electrode w
