Abstract: A stylus pen that can be used as an input device to a digitizer associated with a computer screen on a computing device, such as a computer, mobile device, tablet, etc. The stylus pen can include an end cap that has multiple pressure thresholds for implementing different user-input commands. To detect the pressure being applied to the end cap, the cap is movable relative to a stylus pen body so as to move a plunger in proximity or contact with a mechanical switch. The mechanical switch is a single-action switch that is converted to a dual-action switch by using the electrical conductivity of the switch to detect an electrical coupling between a plunger and the switch. The electrical coupling can be in the form of a capacitive coupling or a direct electrical connection. Further pressure can be detected through actuation of the mechanical switch.

Abstract: The described technology includes a fluid force sensor interface between a pressure sensor, such as a barometric pressure sensor disposed inside a sensor housing with an aperture, and a container with an interior cavity exposed to the ambient environmental fluid pressure. The interior cavity of the container may equalize with the pressure of the ambient fluid environment, and may cooperate with the aperture on the sensor housing to create at least a partial fluid seal. A force member may transmit an applied outside force to deform the container, and the interior cavity therein, to reduce the volume of the interior cavity and thus increase pressure inside the interior cavity. The fluid force sensor may measure the applied force by sensing an increase in pressure inside the interior cavity. After the outside applied force has been removed, the pressure inside the interior cavity may equalize with the ambient fluid pressure.

Abstract: A contact to provide an electrical connection between two circuit boards, such as a rigid circuit board and a flexible circuit board installed in a container, such as an electronic stylus or a cellular telephone. The contact head generally has the shape of an inverted spoon, which allows the contact head to slide smoothly onto a desired electrical contact pad on the flexible circuit board. The contact has a unitary design, including a spring, which reduces the likelihood of damage to the flexible circuit board or to the contact when the rigid circuit board is installed in the electronic stylus. The spring design reduces the likelihood that the contact will be bent when the rigid circuit board is installed, and also allows the contact to be balanced, which is advantageous for wave-soldering operations. The contact also has a pick surface, which is useful in vacuum pick-and-place operations.
