Abstract: A ladder stabilizing system including a pair of mounting assemblies coupled to a lower end of a ladder. Further provided are a pair of stabilizing mechanisms slidably engaged with respect to the mounting assemblies. A pair of feet are pivotally coupled to an associated stabilizing mechanism at a lower end thereof. The feet are adapted to pivot within a plane common to a plane defined by the vertical members of the ladder. Also included is a ladder shoe accessory comprising an elongated member having a rectangular configuration with a lower face and an upper face with a pair of elongated side faces integrally coupled between side edges of the lower face and upper face thereby defining an elongated slot. The upper face further has an elongated slit formed therein and extended between a pair of open ends of the ladder shoe accessory. The feet are adapted to be situated within the elongated slot of the first shoe accessory.

Abstract: A first electrical connector of an interface is provided on a floating plug assembly mounted on one component of a physiological instrument. A second electrical connector of the interface is mounted in a socket assembly constructed in another component that can be coupled to the first component by relative linear translation. Guides located in the socket assembly capture fingers on the plug assembly as the plug assembly is inserted in the socket assembly. The guides orient the plug assembly so that the first connector is correctly aligned with the second connector. The connectors are automatically joined as the first component is coupled to the second component.

Abstract: A mechanical connector (10) for securing together an electrocardiogram monitor (12) and a defibrillator (14). The connector includes a tongue (16) disposed on a side surface (18) of the ECG monitor and a set of angle flanges (22) disposed on the defibrillator. A keyway (52) extends lengthwise at a rearward portion of a channel (36) between the tongue (16) and the side surface (18). A key (50) fits within the keyway (52) when the tongue (16) is slid within the set of angle flanges (22). The key (50) prevents the defibrillator from being fully coupled with an ECG monitor that lacks the corresponding keyway.
