Methods and apparatus to monitor and/or adjust operations of doors are disclosed. An apparatus includes processor circuitry to execute instructions to: monitor a position of a door panel associated with a door system; detect when a beam from a photo-eye sensor associated with the door system is in an unexpected non-triggered state based on the position of the door panel; and generate an alert or notification indicating a significance of the beam in the unexpected non-triggered state.

Methods and apparatus to monitor and/or adjust operations of doors

A door system includes a panel to translate along a normal path between an open position and a closed position in front of a doorway in a wall. The door system further includes a first track to support the panel from an upper portion of the panel, and a second track to extend along the normal path proximate a lower portion of the panel. The door system also includes a spring to urge the panel toward the second track to maintain the panel in the normal path.

Insulated doors with restorable breakaway sections

A door includes a panel assembly including a leading panel and a trailing panel. The leading panel is to be in substantially coplanar alignment with the trailing panel when the panel assembly is in a normal configuration. The leading panel is to be angularly displaced out of coplanar alignment with the trailing panel when the panel assembly is in a dislodged configuration. The door further includes a tension member to connect the leading panel to the trailing panel. The tension member is to resiliently urge the leading panel and the trailing panel toward each other in a horizontal direction. The tension member is to resiliently urge the panel assembly toward the normal configuration when the panel assembly is in the dislodged configuration.

Example seals for insulated doors are disclosed. An example seal for a door includes a first mounting rail and a second mounting rail spaced apart from the first mounting rail. The example seal further includes a flexible sheet extending between the first mounting rail and the second mounting rail. The flexible sheet is to be biased away from the first and second mounting rails to sealingly engage the door when the door is in a closed position.

A medical crutch having a number of bends in the frame for redistributing the amount of pressure applied to a user's hand, arm, and axilla. The frame has a first jog outwardly sidewards relative to a user's body and a second jog outwardly forward relative to the user's body. The frame may attach an adjustable handle, forearm rest and underarm support, among other attachments. The frame is adapted to fit all average sizes by adjusting the positions of the attachments.
