TL;DR: A force sensing touchpad as discussed by the authors comprises a substantially rigid touch surface, a substantial rigid frame, a plurality of spring structures formed integrally with the touch surface and mechanically connected to the reference frame, and a circuit for deriving force information.
Abstract: A force sensing touchpad comprises a substantially rigid touch surface; a substantially rigid frame; a plurality of spring structures formed integrally with the touch surface and mechanically connected to the reference frame; and a circuit for deriving force information from capacitances proportional to the distances between predetermined portions of the touch surface and portions of the frame in response to a force applied to the touch surfaces.

TL;DR: It is shown that a multi-graph can be realized as a rigid linkage of rigid bodies in n-space if and only if it contains n(n + 1)2 edge disjoint spanning trees.

TL;DR: In this paper, the relationship between forces and displacements at the ends of a member with elastically restrained ends is derived in matrix form and the force components, in terms of the end displacements, are arranged in a matrix form.
Abstract: Frames with semi-rigid connections are investigated. Relationships between forces and displacements at the ends of a member with elastically restrained ends are derived. The force components, in terms of the end displacements, are arranged in matrix form. Stiffness matrices of a member with elastic restraint at the ends are presented, in the form of the stiffness matrices for members with rigid connections, modified by a correction matrix whose elements are functions of parameters, designated as fixity factors of the member. A formula for the force components at the ends of all the members of a frame is established. The matrix operations involved are conveniently performed by any digital computer, and problems ranging from rigid frames to pin-connected trusses can be solved by the same systematic approach. Several numerical examples are solved.
