Claim Text:
1. A medical cart, comprising: a cart base assembly including a support platform, a first pressure-sensitive foot panel having a first contact switch, a second pressure-sensitive foot panel having a second contact switch, and a support structure positioning the first and second foot panels generally below the support platform, wherein the first foot panel includes a resilient cover having a first contact surface, and the first contact switch underlies a portion of the first contact surface, wherein the resilient cover is a single piece of resilient material covering the first and second switches, wherein the resilient material includes a non-contact portion between the first and second foot panels, and a portion having a second contact surface overlying the second contact switch, and wherein the support structure positions the first contact surface in a forward-facing direction that faces away from the support platform, and the second contact surface in a forward-facing direction that faces away from the support platform; a work platform; a height adjustment assembly carrying the work platform above the cart base assembly, wherein the height adjustment assembly includes a linear actuator for vertically lifting the work platform relative to the support platform; and a controller operably coupled to the linear actuator and the contact switch, wherein the controller is configured to: detect for operator foot contact at the first contact surface via the first contact switch, and raise the work platform via the linear actuator when operator foot contact is detected via the first contact switch, detect for operator foot contact at the second contact surface via the second contact switch, and lower the work platform via the linear actuator when operator foot contact is detected via the second contact switch.
