Some aspects include a ski binding system using a controllable solenoid. In some aspects, microprocessor-based control releases binding electronically based on input from sensors located in binding, ski and/or boot, as well as in other equipment or clothing connected to them or to skier, or binding releases when a mechanical threshold is overcome. In some aspects, sensor data are recorded for analysis of system performance and for adjustment and improvement of system parameters based on data analytics. ## Claims ### Claim 1 Apparatus for use in releasably retaining a boot plate to a ski, the boot plate comprising a material attracted by a magnetic field, the apparatus comprising: a binding plate attachable to the ski, the binding plate including a surface to receive the boot plate and an electromagnet to receive electrical power and provide a magnetic force in response thereto to attract the boot plate to the surface of the binding plate, wherein the binding plate comprises a toe plate and a heel plate spaced apart from the toe plate, wherein the toe plate includes the electromagnet and wherein the heel plates includes an electromagnet to receive electrical power and provide a negating magnetic force in response thereto to release the boot plate from the surface of the binding plate. ### Claim 2 (depends on 1) The apparatus of claim 1 further comprising a control system coupled to the electromagnet. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the surface of the binding plate includes a raised portion. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the binding plate includes a plurality of electromagnets to receive electrical power and provide a magnetic force in response thereto to attract the boot plate to the surface of the binding plate. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the surface of the binding plate includes a plurality of raised portions. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the surface of the toe plate defines one of the plurality of raised portions and wherein the surface of the heel plate defines another of the plurality of raised portions. ### Claim 7 Apparatus comprising: a boot plate comprising a material attracted by a magnetic field; a binding plate attachable to a ski, the binding plate including a surface to receive the boot plate and an electromagnet to receive electrical power and provide a negating magnetic force in response thereto to release the boot plate from the surface of the binding plate, wherein the surface of the binding plate includes a raised portion and wherein the boot plate defines an indentation to receive the raised portion. ### Claim 8 (depends on 7) The apparatus of claim 7 further comprising a control system coupled to the electromagnet. ### Claim 9 (depends on 7) The apparatus of claim 7, wherein the boot plate comprises a ferromagnetic material. ### Claim 10 A snow sport boot binding comprising: a boot plate comprising a material attracted by a magnetic field; and a binding plate attachable to a ski, the binding plate including a surface to receive the boot plate and an electromagnet to receive electrical power and provide a negating magnetic force in response thereto to release the boot plate from the surface of the binding plate; wherein the surface of the binding plate includes a plurality of raised portions and wherein the boot plate defines a plurality of indentations to receive the plurality of raised portions.
