  • Patent number: 10348871
    Abstract: Disclosed here are systems and methods which enable high-bandwidth communication between a mobile device and an accessory. The high-bandwidth communication uses electromagnetic waves in the extremely high frequency range between 30 GHz and 300 GHz inclusive, also known as millimeter waves. The millimeter waves travel through at least the chassis of the accessory and the chassis of the mobile device without significant scattering and attenuation. The properties of the materials through which the millimeter waves travel determine the attenuation of the millimeter waves. Disclosed here are various materials, and their thicknesses, which form a transmission stack through which the millimeter waves can travel unimpeded. In effect, the transmission stack acts as a dielectric member which facilitates the transmission of the millimeter waves, while attenuating transmission of waves outside of the extremely high frequency range.

  • Patent number: 9976923
    Abstract: A pressure sensor comprises an operating circuit and a pressure-measuring cell comprising a counter body, a measurement membrane, which is arranged on the counter body and can be deformed by a pressure to be measured, and a capacitive transducer, which has at least one membrane electrode arranged on the measurement membrane and at least one counter-body electrode arranged on the counter body. The capacitance between the membrane electrode and the counter-body electrode depends on a pressure-dependent deformation of the measurement membrane, wherein at least the membrane electrode has a temperature-dependent impedance. The operating circuit is designed to sense at least one capacitance between the at least one counter-body electrode and the at least one membrane electrode and to provide a pressure measurement value on the basis of at least one capacitance and to determine the impedance of the membrane electrode—particularly, the ohmic portion of the impedance of the membrane electrode.

  • Patent number: 9400582
    Abstract: Electronic devices may use touch pads that have touch sensor arrays, force sensors, and actuators for providing tactile feedback. A touch pad may be mounted in a computer housing. The touch pad may have a rectangular planar touch pad member that has a glass layer covered with ink and contains a capacitive touch sensor array. Force sensors may be mounted under each of the four corners of the rectangular planar touch pad member. The force sensors may be used to measure how much force is applied to the surface of the planar touch pad member by a user. Processed force sensor signals may indicate the presence of button activity such as press and release events. In response to detected button activity or other activity in the device, actuator drive signals may be generated for controlling the actuator. The user may supply settings to adjust signal processing and tactile feedback parameters.

It further contains electrically actuatable selection means, by means of which one of the measuring capacitors can be selected in such a way that only the selected measuring capacitor contributes to the measurement, whereas the other measuring capacitors do not. As a result, the total capacitance of the measuring circuit is reduced and its sensitivity is increased.
