A foot switch (1, 26) for use with a medical device (16, 27, 28) comprises an interface (10) for a communications link between the foot switch (1, 26) and a control unit (12) of the device (16, 27, 28) and comprises at least one pedal (2, 3) for operating the foot switch (1, 26) using a foot. An operation sensor (17) captures an operation of the foot switch (1, 26) for switching a function of the medical device (16, 27, 28). The control unit (12) assigns the function to the pedal (2, 3) via the interface (10) and the assigned function is displayed on the foot switch (1, 26) by a multicolor LED (4, 5).

A door leading edge sensor has a door leading edge elastic member which is attached to a front end portion of a door in a door closing direction and includes a cavity extending in a direction intersecting with the closing direction; a linear pressure sensitive sensor is attached to the door leading edge elastic member and is disposed along the extending direction of the cavity. The pressure sensitive sensor has an insulator tube having such an elasticity as to be deformed in accordance with an elastic deformation of the door leading edge elastic member and has plural conductive members fixed to an inner surface of the insulator tube. The plural conductive members are in a non-contact state when the insulator tube is not deformed and are in contact with each other when the insulator tube is deformed.

A pressure-sensitive sensor, includes a hollow tubular member including an elastic insulating material; and n electrode wires (n being an integer of not less than 3) arranged away from one another and held inside the tubular member, wherein when an external pressure is applied to the tubular member, the tubular member elastically deforms such that at least two of the n electrode wires contact with each other, and wherein the n electrode wires extend linearly and parallel to a central axis of the tubular member.

The present disclosure provides a method, including acquiring information related to foot gesture features, and sending the acquired information related to the foot gesture features to an electronic device for a foot gesture detection. The foot gesture features include foot pointing direction(s), foot touch state(s), foot tilt angle(s), and foot movement levels. A button pad device that can be placed in shoe sole or insole for effective foot touch state detection is also disclosed. The disclosure also provides a method for cursor control using foot touch state, foot pointing angle, foot tilt angle from a foot gesture feature information acquisition device.

The disclosed apparatus, system and method may include at least a phacoemulsification surgical console having a customizable non-linear custom phacoemulsification mode. The apparatus, system and method may include an ultrasonic delivery tip; a foot pedal; and non-transitory computing code resident on a computing memory associated with a computing processor which, when executed by the processor, causes to be executed the steps of: receiving a percentage actuation of the foot pedal; calculating, including from a non-linear algorithm, a percentage actuation for the ultrasonic delivery tip corresponded to the received percentage foot pedal actuation; and dictating the calculated percentage actuation for the ultrasonic delivery tip actuation to the ultrasonic delivery tip.
